Abstract: DNA sequences which function specifically in the synthesis of 2,4-diacetylphloroglucinol (Phl) are described. The sequences include phl genes which encode phl gene proteins and coding and regulatory sequences for production of Phl as well as sequences containing phl genes, which sequences have the capability of conferring or enhancing Phl biosynthetic capability in bacterial strains. The transformed strains are useful as biocontrol agents against fungal pathogens.

Description: SEQUENCES FOR PRODUCTION OF 2,4-DIACETYLPHLOROGLUCINOL AND METHODS FIELD OF THE INVENTION The present invention relates to materials and methods for improved control of plant pathogens. More particularly, the present invention relates to the identification, isolation, cloning, and sequencing of genetic elements which confer or enhance the ability of an organism to produce the antibiotic 2,4- diacetylphloroglucinol, and uses thereof, particularly the use to transform an organism to introduce or enhance 2,4- diacetylphloroglucinol biosynthetic capability. BACKGROUND OF THE INVENTION Rhizobacteria are plant-associated bacteria, derived from many genera, that have the ability to colonize roots aggressively (Schroth and Hancock, Ann . Rev. Microbiol . 35:453-576 (1981)). Plant growth-promoting rhizobacteria (PGPR) also are able to improve plant growth either through direct effects, on the plant (Lugtenberg et al., Curr. Opin . Biotechnol . 2:457-464 (1991)) or by suppressing soilborne plant pathogens (0'Sullivan and O'Gara, Microbiol . Rev. 56:662-676 (1992); Weller, Ann. J?ev. Phytopathol . 26:379-407 (1988)). PGPR when applied to soil, seeds or seed pieces, colonize the surface or inside of roots and channels in the rhizosphere that allow physical access to the root. Thus, they are ideally positioned to limit the establishment or spread of pathogens on the roots. Bacteria introduced for the purpose of suppressing soilborne plant pathogens may interact with pathogens directly through one or more mechanisms of antagonism including competition, parasitism and predation, and antibiosis, or they may function indirectly to limit the initiation or spread of disease by triggering systemic defense responses in the host plant. It has become increasingly clear over the past decade that antibiosis, the inhibition or destruction of one organism by a metabolic product of another, has a dominant role in the control of several important fungal root and seed pathogens by bacterial biocontrol agents, and especially by fluorescent Pseudomonas species (Weller and Thomashow, pp. 173- 180 in Pest Management : Biologically Based Technologies, R. D. Lumsden and J. L. Vaughn, eds. (1993)). Pseudomonas is one of comparatively few bacterial genera capable of synthesizing an array of compounds with broad-spectrum antibiotic activity, and many of the most efficient bacterial biocontrol agents are fluorescent Pseudomonas strains. Antibiotics produced by strains of fluorescent Pseudomonas spp. with biocontrol activity include pyoluteorin and pyrrolnitrin, implicated in control of damping-off diseases of cotton caused by Pythium ultimum and Rhizoctonia solani (Howell et al.. Phytopathology 69:480-482 (1979) and Phytopathology 70:712-715 (1980)); oomycin A, also involved in suppression of damping-off of cotton caused by P. ultimum (Gutterson, Crit . Rev. Biotechnol . 10:69-91 (1990)); 2,4-diacetylphloroglucinol, involved in control of take-all disease of wheat caused by Gae mannomyces graminiε var. tritici (Harrison et al.. Soil Biol . Biochem. 25:215-221 (1993); Keel et al., Λfol. Plant-Microbe Interact . 5:4-13 (1992); Vincent et al., Appl . Environ . Microbiol . 57:2928-2934 (1991)); and phenazine-1-carboxylic acid and its derivatives, active in suppression of take-all (Tho ashow et al., J. Bacteriol . 170:3499- 3508 (1988); Pierson et al., Mol . Plant-Microbe Interact . 5:330- 339 (1992)). Of these pathogens, Gaeumannomyces graminis and J_hi_rocto.πia species are particularly problematic because there are no satisfactory seed treatments for their control. Rhizoctonia and Pythium species are important because they can infect and causing damping-off and root rot diseases in a wide variety of crop plants. For these reasons, biocontrol agents active against these pathogens are of substantial interest to agriculture. Whereas most individual biocontrol agents function acceptably only within fairly limited circumstances, biologically active plant-associated microorganisms in the aggregate have almost unlimited genetic biodiversity and are adapted to a wide range of environments. Thus, biocontrol agents that can both antagonize plant pathogens and compete successfully with the indigenous rhizosphere microflora of diverse crops or agroecosystems, are desirable. One proposed approach to obtain such biocontrol agents is to identify genetic elements that can confer or enhance the antifungal activities of rhizosphere colonists indigenous to and highly competitive in the plant and ecological environments where biological control is needed, and use these elements to genetically engineer strains of biocontrol agents. It is preferred that the biocontrol agents combine the ability to control the growth of one or more fungal pathogens with other desirable attributes such as adaptation to a particular host plant or environment or the ability to rapidly achieve peak growth rates. The antibiotic 2,4-diacetylphloroglucinol (Phi) is a phenolic compound of possible polyketide origin with antifungal, antibacterial, antiviral, antihelminthic and phytotoxic properties. Phi is produced by fluorescent pseudomonads that suppress root diseases caused by a variety of soilborne plant pathogens of crops around the world. These include root rot of wheat caused by Fusarium oxysporum, black root rot of tobacco caused by Thielaviopsis basicola (Keel et al.. Symbiosis 9:327-341 (1990); damping-off of sugar beet caused by Pythium ultimum (Fenton et al., Appl . Environ . Microbiol . 58:3873-3878 (1992)); damping-off of cotton caused by P . ultimum and Rhizoctonia solani (Kraus et al.. Phytopathology 82:264-271 (1992)), blotch of wheat caused by Septoria tritici (Levy et al.. Plant Pathol . 41:335-341 (1992)), and take-all of wheat caused by Gaeumannomyces graminis (Harrison et al., supra; Keel et al., (1992) supra; Vincent et al., supra). Strains that produce Phi therefore have considerable agricultural significance. Three classes of DNA clones have been reported to affect Phi production. The first class contains genes including gacA (Laville et al., Proσ. Natl . Acad. Sci . USA 89:1562-1566 (1992)), 2emA (PCT Application WO 94/01561; Corbell et al., Λfol. Ecol . 3:608 (1994)) and rpoS (Sarniguet et al., Mol . Ecol . 3:607 (1994)), the products of which function as global regulators of a variety of secondary metabolic pathways including that for the synthesis of Phi, thereby indirectly influencing Phi production. The second class includes DΝA sequences of unknown function encoded on the plasmids pME3128 (Keel et al., 1992, supra) and pME3090 (Maurhofer et al.. Phytopathology 82:190-195 (1992)) from strain CHA0. The former complemented the Tn5 Phi " mutant CHA625 to Phl + and the latter was selected for its ability to cause overproduction of pyoluteorin when introduced into wild-type CHA0; it subsequently was found also to increase Phi production by about 50%. Neither of these loci has been implicated directly in Phi synthesis, nor reported to be able to confer Phi production to strains deficient in this capacity. A third class of DNA sequences known to influence Phi production includes those reported by Vincent et al., supra; Fenton et al., supra, and Hara, et al. (Hara et al., pp. 247-249 in Improving Plant Productivity with Rhizobacteria , Ryder, Stephens and Bowen, eds. (1994)) that are capable of transferring Phi biosynthetic capability. Vincent et al., supra, described a locus from P. fluorescens (formerly aureofaciens ) Q2-87 (Pierson and Weller, Phytopathology 84:940-947 (1994)) that, when disrupted with the transposon Tn5, resulted in the mutant Q2-87: :Tn5-l, which was unable to synthesize Phi. Either of two cosmid clones designated pMON5117 and pMON5118 and isolated from genomic DNA of strain Q2-87 restored antifungal activity and Phi production to Q2-87: :Tn5-l. Mobilization of pMON5118 into two Phl-nonproducing strains conferred the ability to synthesize Phi and increased their antagonistic activity in vitro against Gaeutπani-ojπyσes graminis, Pythium ultimum, and Rhizoctonia solani . Vincent et al. did not provide any information as to whether a particular portion of the cloned fragment was required, or if the transferred sequences functioned indirectly as a global regulator or specifically to encode enzymes that catalyze the synthesis of Phi. Fenton et al., supra, reported that pCU203, containing a 6-kb fragment of DNA cloned from P. fluorescens F113, partially restored Phi production to a Phi" Tn5 mutant of F113 and transferred Phi biosynthetic capability only to M114, one of eight nonproducer strains into which it was introduced. Strains Fll3(pCU203) and M114(pCU203) were more inhibitory to P. ultimum in vitro and increased sugarbeet seedling emergence in soil relative to the parental strains. The 6-kb fragment carried monoacetylphloroglucinol transacetylase activity (Shanahan et al.. Anal . Chem. 272:271-277 (1993)). Fenton et al. did not indicate that a particular portion of the cloned fragment was required, or if the transferred sequences functioned indirectly as a global regulator or specifically to encode enzymes that catalyze the synthesis of Phi. Shanahan et al. likewise did not specify what portion of the 6-kb fragment was required for the transacetylase reaction, nor did they indicate or suggest that the fragment contains genetic information suf_ .cient to encode the full complement of enzymes required to catalyze Phi biosynthesis. Neither Shanahan et al. nor Fenton et al. have demonstrated that the transacetylase activity is required for or participates in the Phi biosynthetic pathway in F113. Hara et al., supra, reported that all of eight strains of Phl- nonproducing strains of fluorescent Pseudomonas spp., when transformed with the plasmid pPHL5122 containing a 7-kb fragment of DNA from Q2-87, produced Phi, and that the overall severity of take-all was reduced on seedlings of wheat treated with strains that contained the cloned Phi locus as compared to those treated with unmodified parental strains. Hara et al. did not indicate whether a particular portion of the cloned fragment was required, or suggest any particular biological function, e.g., catalytic or regulatory, for the transferred sequences. SUMMARY OF THE INVENTION The present invention comprises DNA sequences in isolated and purified form which function specifically in the biosynthesis of 2,4-diacetylphloroglucinol (Phi) and which can effect the production of 2,4-diacetylphloroglucinol (Phi). By effecting production of Phi, is meant that, a DNA sequence of the invention (1) is capable of conferring the ability to produce Phi in a Phl- nonproducing bacterial strain transformed with the sequence; (2) is capable of enhancing Phi production in a Phi-producing bacterial strain transformed with the sequence, or (3) is capable of both conferring and enhancing Phi production. In effecting production of Phi, a sequence of the invention may function in the biosynthesis of Phi, the regulation of the biosynthesis of Phi, the export of Phi from the producing cell, the modulation of Phi production or activity, or all of the foregoing. Sequences which function specifically in the biosynthesis of Phi include those encoding catalytic enzymes and regulatory proteins specific for the Phi biosynthetic pathway, proteins that export Phi, and sequences that modulate Phi production or activity. The genetic elements containing the Phi locus are illustrated in FIG. 1, and the sequence data are given in SEQ ID NO: 3. As discussed in detail below, biosynthetic, bioregulator, export, and modulator elements are contained within the locus. The present invention also encompasses sequences shorter than SEQ. ID NO:3 which have the ability to effect Phi production. The present invention further comprises DNA sequences in isolated and purified form for phlA, phlB , phlC, phlD, phlE, phlF, and phlR genes, which genes function in the production of Phi. The aforenamed genes encode proteins, which proteins function in the production (synthesis, regulation of synthesis or modulation) of Phi in bacteria. Genomic sequences encoding particular phi gene biosynthetic proteins are specifically exemplified herein. DNA sequences which hybridize specifically to phi biosynthetic gene coding sequences or to their components under standard conditions and which encode phi gene proteins which function in the biosynthesis of Phi are also encompassed by the present invention. DNA sequences which function to regulate the biosynthesis of Phi include regulatory and coding sequences which influence expression of the Phi biosynthetic sequences and Phi biosynthetic capability. In particular, a DNA sequence is described which encodes a repressor of Phi biosynthesis, which protein has the function of repressing (stopping) the expression of phi biosynthetic genes in bacteria that can otherwise synthesize Phi. Truncation of the repressor sequences resulted in loss of regulation of the phi biosynthetic sequences, and overproduction of Phi. The modification of these regulatory and coding sequences to modulate Phi production or to enhance the biocontrol capability of the host bacterial strain is also part of the present invention. Genomic sequences encoding a particular phi repressor gene protein, and a truncated derivative thereof, are specifically exemplified herein. DNA sequences that hybridize specifically to the phi repressor gene or its complement under standard conditions and which encode repressor genes that function to modulate or repress expression of phi biosynthetic genes are included in the present invention. The present invention further comprises recombinant nucleic acid molecules containing a sequence of the invention. Such molecules include, for example, recombinant vectors, such as cloning, expression, or transformation vectors, which contain a DNA sequence which affects the production of Phi. The invention encompasses recombinant nucleic acid molecules which contain a bacterial regulatory element operably linked to a DNA sequence of the invention. The bacterial regulatory element may be a promoter from a gene isolated from Pseudomonas, Bacillus, Escherichia coli , or any other bacterium. In one embodiment of the present invention, the bacterial regulatory element is the native promoter of the sequences encoding for the production of Phi. The bacterial regulatory element may be from a gene which is homologous or heterologous to genes of the host bacterial strain. Another aspect of the invention is the provision of cells which are transformed by the above vectors or DNA sequences. A particular use of the invention is the provision of bacteria, bacterial biocontrol agents, or bacterial cells transformed with sequences that confer or enhance the ability of the bacteria or bacterial cell to produce Phi. Using the sequences of the invention, biocontrol agents can be produced which combine the ability to control growth of a plant pathogen and to compete aggressively in colonization of the plant rhizosphere. Further, the sequences of the invention contribute to the production of biocontrol agents which are able to inhibit a broad spectrum of plant pathogens. The present invention also comprises methods of conferring or enhancing Phi biosynthetic capability in a host bacterial strain by transforming the host strain with the recombinant DNA sequences of the present invention. In a particular embodiment of the present invention, the transformed host strain is rendered active or more effective against fungal plant pathogens such as Gaeumannomyces graminis, Rhizoctonia εolani , and species of the genera Pythium and Fusarium. The present invention also comprises methods of conferring or enhancing Phi biosynthetic capability in a host bacterial strain by introducing the DNA sequence into the genome of a host bacterial strain. In the preferred embodiments of the invention, the host bacterial strain may be a pseudomonad, particularly strains of the species Pseudomonas fluorescens . The present invention further comprises DNA sequences in isolated and purified form that can be used as probes or oligonucleotide primers for the identification of phi genes or functional equivalents thereof in bacterial strains and the use of such probes or primers to isolate Dϊ_. sequences encoding phi genes or functional equivalents thereof. The DNA sequences that specifically hybridize to the probes or primers and which encode functional phi genes are encompassed by the present invention. Further, because bacterial strains that contain phi genes are of potential value as biocontrol agents, the use of any portion of the DNA sequences that confer or enhance Phi biosynthetic capability to identify other strains of bacteria with potential Phi biosynthetic capability is included in the present invention. Accordingly, it is one object of the present invention to provide DNA sequences and genes that confer or enhance Phi biosynthetic capability in bacterial strains. It is another object of the present invention to provide gene constructs comprising DNA sequences which have the function of conferring or enhancing Phi biosynthetic capability in bacterial strains. It is another object of the present invention to provide transformation vectors comprising phi gene constructs, which vectors are effective for stably introducing phi gene constructs into bacteria. It is a further object of the invention to provide transgenic bacterial strains wherein the capability to produce Phi has been conferred or enhanced as a result of the introduction of phi gene constructs. It is another object of the invention to provide transgenic bacterial strains enhanced in biocontrol activity against fungal pathogens, wherein the enhancement results from introduction of phi gene constructs. It is a further object of the present invention to provide DNA sequences for use as probes or primers in the identification of strains of bacteria with potential biocontrol activity. Further, DNA sequences and genes are provided as probes and primers for the isolation of homologous genes from related and unrelated hosts. Using such sequences facilitates the identification of genes and the hosts strains harboring them for protection of plants against fungal pathogens. It is a further object of the present invention to provide DNA sequences and genes which encode proteins that function in the production of Phi, including DNA sequences and genes which encode modified proteins that modulate the production of Phi in bacterial strains. Such modifications may alter the activity of regulatory genes, the expression of phi genes encoding biosynthetic proteins, and the biocontrol activity of host bacterial strains. According to the present invention, the above objectives may be carried out by the isolation and use of DNA sequences that confer or enhance the production of 2,4-diacetylphloroglucinol in bacterial strains. The isolation of these genes and associated regulatory sequences is important for several reasons. First, in bacterial strains they confer or enhance the production of Phi, which is able to inhibit a wide range of fungal plant pathogens including Gaeumannomyces graminis, Rhizoctonia solani, and species of the genera Pythium and Fusarium. Secondly, they can function as probes and primers to screen for and identify naturally- occurring strains of bacteria with Phi biosynthetic capability. The use of bacterial strains transformed with DNA sequences that confer or enhance the production of Phi, or of Phi-producing strains identified by use of probes or primers derived from such sequences, provides an environmentally safe and effective method for control of these pathogens. Examples of the sequences conferring Phi biosynthetic capability of the present have been deposited. Accordingly, the sequences conferring or enhancing Phi biosynthetic capability include the exemplified or deposited DNA sequences as well as the fragments derived from the exemplified or deposited sequences. By fragment is intended a DNA sequence which is capable of functioning to confer or modulate Phi biosynthetic capability or to identify the potential for such capability in bacteria. The present invention further includes portions of such DNA fragments which function specifically in the synthesis of Phi but may not in themselves be sufficient to effect the production of PHL in transformed cells. Other objects and advantages of this invention will become readily apparent from the ensuing description. DEFINITIONS As used in the present application, the following terms have the meaning set out below: Promoter or regulator DNA sequence: An untranslated DNA sequence which assists in, enhances, or otherwise affects the transcription, translation, or expression of an associated structural DNA sequence which codes for a protein or other DNA product. The promoter DNA sequence is usually located at the 5' end of a translated DNA sequence, typically between 20 and 100 nucleotides to the 5' end of the starting site for translation. Structural or coding DNA sequence: A DNA sequence that is translated or transcribed in an organism to produce an RNA, a protein, or other DNA product. Associated with/operably linked: Two DNA sequences which are "associated" or "operably linked" are related physically or functionally. For example, a promoter or regulator DNA sequence is said to be "associated with" a DNA sequence that codes for an RNA or a protein if the two sequences are operably linked, or situated such that the regulator DNA sequence will affect the expression level of the coding or structural DNA sequence. Derived from: A first DNA sequence or fragment is said to be "derived from" a second DNA sequence or fragment if the former is physically isolated from the latter, or if the former is isolated by using part or all of the latter as a probe for isolation. Substantial sequence homology: A sequence having substantial functional and structural equivalence between sequences of nucleotides or amino acids. In the case of a nucleotide sequence, a sequence having substantial sequence homology will have at least 70%, preferably 85%, and more preferably 90% homology to a reference nucleotide sequence, as opposed to nonspecific binding, and function specifically in the biosynthesis of Phi. Homologous sequences can be identified in a hybridization experiment. Conditions of high and low stringency are described below. In the case of amino acid sequences, the different sequences have at least 70%, more preferably 80%, and most preferably 90% or more similarity between the polypeptides coded for by the amino acid sequences and function specifically in the biosynthesis of Phi. Locus: A segment of DNA that includes one or more coding or regulator DNA sequences that specifically affect a particular phenotypic trait. Transformed cell: A cell or an ancestor of a cell that contains DNA introduced by the hand by any means known to the art, including but not limited to transformation, conjugation, and electroporation.

Proposed biosynthetic pathway for 2,4- diacetylphloroglucinol, adapted from D. E. Metzler, BIOCHEMISTRY, The Chemical Reactions of Living Cells . Chain building is thought to be initiated by the condensation of an acyl thioester "starter" unit with a malonyl "extender" unit to yield C0 2 plus a 4 C acetoacetyl intermediate which is then further elongated by sequential condensation reactions with additional acetyl groups donated by malonyl extender units. Monoacetylacetylphloroglucinol (MAPG) could then be formed as shown. The conversion of MAPG to 2,4-diacetylphloroglucinol (Phi) by an enzyme designated MAPG acetyltransferase has been demonstrated in vitro by P. fluorescens F113 by Shanahan et al. Whether Phi also may arise directly by cyclization of a ketodecanoyl thioester intermediate is not known. Figure 5. Similarity of PhlC to the thiolase portion of sterol carrier protein x (SCPx) .

DETAILED DESCRIPTION OF THE INVENTION The present invention provides DNA sequences in isolated and purified form which function specifically in the biosynthesis of 2,4-diacetylphloroglucinol (Phi) and which can effect the production of Phi by conferring or enhancing the ability of an organism to produce Phi. Manipulation of these genetic elements, either separately or in combination, can be used to introduce or enhance biosynthetic capability in organisms transformed with the sequences. In particular, we have identified, cloned, and sequenced DNA sequences from Pseudomonas fluorescens Q2-87 and used the sequences to introduce Phi biosynthetic capability in Phl- nonproducing bacterial strains. We also have determined that strains of Pseudomonas capable of producing Phi, when transformed with these sequences, are enhanced in Phi production. Further, bacterial biocontrol agents transformed with these sequences produce Phi and are enhanced in their biocontrol activity. The present disclosure is the first report of the cloning, sequencing and reproducible mediation of transgenic Phi production by phi genes of Pseudomonas . The phi genes include genomic sequences which encode phi gene proteins and coding and regulatory sequences which direct and regulate the transcriptional and translational expression of the phi-coding sequences. As defined herein, "phi gene proteins" refers to proteins having the ability to function in the production of 2,4-diacetylphloroglucinol in bacteria synthesizing phi gene proteins. The phi locus is that segment of DNA that encompasses the coding and associated regulator DNA sequences that specifically encode the ability to confer or enhance Phi production.

A truncated genomic DNA sequence (from pMON5122) is given in SEQ ID NO:4. The degeneracy of the genetic code is well known to the art; therefore, synonymous coding sequences with one or more codon substitutions can be readily determined by one of ordinary skill in the art.

This sequence encompasses that of SEQ ID NO:2 and 1094 contiguous bases which include regulatory sequences and a portion of the phlF open reading frame initiating at base 5781 and terminating at base 6170. The truncated phlF protein is 130 amino acids in length. Its DNA coding and amino acid sequences are given in SEQ ID NO:19 and SEQ ID NO:20, respectively. When transformed into bacterial strains, the sequences present in SEQ ID NO:4 confer or enhance Phi production. The DNA sequence of SEQ ID NO:4 is contained within a Sa2I-2-coRI fragment of 6586 bp in the plasmid pPHL5122, which was deposited under terms of the Budapest Treaty June 21, 1995, in the Agricultural Research Culture Collection (NRRL), 1815 North University Street, Peoria, Illinois, and has been designated NRRL accession number B-21476. Nucleotide and amino acid sequences having substantial sequence homology to the exemplified or deposited sequences are encompassed in this invention. Sequences for Phi Production Genomic sequences capable of inducing Phi production may transfer either gene(s) that encode biosynthetic enzymes or a positive regulatory element that can activate the expression of unassociated and unexpressed (cryptic) genes indigenous to the host strain. Examples of cryptic genes that have been activated by introduction of positive regulatory elements include those for the synthesis of Phi and HCN. Mutations in genes encoding positive regulators typically have a complex phenotype because the functional gene product is unavailable to activate the expression of other genes, including those for the production of Phi and HCN. We found no evidence that Phi production in the transformed strains could be explained by introduction of a positive global activator of gene expression. We have found that DNA sequences encompassing production of Phi are contained within a DNA fragment encompassing five genes, phlACBD and phlR (Figure 1), and that the coding sequences of these genes predict proteins with catalytic activities consistent with roles in the biosynthesis of Phi. Of the DNA fragments from P. fluorescens Q2-87 implicated by Vincent et al. in the production of the Phi, only the fragment designated pMON5122 was able to transfer Phi biosynthetic capability to the Phl-nonproducing strain P . fluorescens M4-80R (Example 1; Table 1). Fragments smaller than that in pMON5122 were unable to transfer Phi biosynthetic activity, suggesting that essential sequences had been deleted, and fragments larger than pMON5122 also failed to confer biosynthetic capability, suggesting that they contained negative regulator sequences. The cloned fragment from pMON5122 was transferred to the plasmid pVSP41, a vector which is stably maintained in Pseudomonas in the absence of antibiotic selection, and introduced into five Phl-nonproducing strains and into Q2-87. Derivatives of all of Phl-nonproducing strains containing pPHL5122 produced Phi but were unaltered in other phenotypes including production of HCN. Phi production by Q2-87(pPHL5122) was enhanced over that by Q2-87 alone or that by Q2-87(pVSP41) , the vector-bearing strain (Example 1, Table 2) . Q2-87: :Tn5-l, shown by Vincent, et al. to be defective in Phi production, contains the transposon Tn5 within a genomic copy of the sequences cloned on pPHL5122. Phenotypic characterization Q2- 87::Tn5-l revealed that it remained HCN + . Field studies of strains containing the cloned sequences that confer or enhance Phi production will require that introduced genes be stably incorporated into the chromosome of the host strain. As illustrated in Example 1, below, we used the ini- transposon vector pUT mini-Tn5 Km (de Lorenzo and Timmis, Meth . in Enzymol . 235:386-405 (1994)) to transfer sequences from pMON5122 to the chromosomes of rhizosphere pseudomonads including strains Q69c-80, Q65c-80, and the phenazine antibiotic-producing strains 2-79 and 30-84. Other materials for stable introduction are known to those in the art and are encompassed by this invention. To confirm insertion of the mini-Tn5 vector, the kanamycin- resistant transposition derivatives of Q69c-80 were characterized. Results from Southern hybridization indicated that single copies of the Phi genes had transposed to different sites in individual derivatives, and all of the derivatives initially produced Phi in vitro. Quantities of Phi sometimes were over twenty-fold greater than produced by Q69c-80(pPHL5122) (Example 1; Table 3), and Phi usually was not detectable in cultures of strain Q2-87 grown under comparable conditions. The reproducibility of transfer and the specificity of the affected phenotype in these studies indicate that sequences present on pMON5122 include genes encoding a Phi biosynthetic pathway, rather than a global activator of Phi synthesis. The portion of pMON5122 active in Phi production was defined by mutagenesis with the transposon Tn3HoHol (Stachel et al., EMBO J. 4:891-898.(1885)). The site and orientation of each insertion were determined (Example 2; Figure 2), and the effect on Phi production and expression of the tra,- sposon-encoded lacZ gene were evaluated after introduction of the mutated plasmids into the Phl- nonproducing strain M4-80R. All insertions which resulted in expression of lacZ , except three, were similarly oriented, only the Lac + insertions 2 and 3 at the right end and insertion 38 at the left end of the cloned fragment had the opposite orientation (Example 3; Figure 2). Insertions resulting in reduction or loss of Phi production, spanned approximately 5 kb of the 6.5 kb fragment and delineated at least two similarly oriented transcriptional/translational units (Example 2; Figure 2, Table 4). These results show that not all of the sequences present on pMON5122 are necessary for Phi production. As shown in Example 2 below, whereas all insertions up to and including number 18 that were Phi " also also failed to produce the red pigment, insertions downstream of number 18 exhibited different phenotypes. Most of these insertions had no effect on Phi synthesis (Table 4) and transformants containing the mutated plasmids had the characteristic red color. However, insertion derivatives 20, 25, and 33 exhibited a level of Phi production that was intermediate between the positive and negative controls, remained inhibitory to C. michiganensis subsp. michiganensis in vitro (Table 4), and failed to exhibit red pigmentation. The region containing insertions 20, 25 and 33 is designated Red" in Figures 1 and 2 and is considered to provide a function that enhances, but is not required for Phi production in M4-80R. Subclones spanning the ca. 5-kb region were generated (Figure 3) and submitted to the Nucleic Acid Sequencing Facility, Iowa State University, for sequence determination. Using the Genetics Computer Group (GCG) package as supported by the Washington State University VADMS facility, we have identified six large complete open reading frames, designated phlA , phlB , phlC, phlD, phlE , and (in the opposite orientation) phlR within this region (Figure 1). The fragment containing phlA through phlD encoded on one DNA strand, with phlR on the other strand, contains genes necessary to confer or enhance Phi production, and phlD is required for the synthesis of Phi. A larger fragment encompassing the above plus the adjacent phlE gene can confer or enhance Phi production and includes an additional gene, the product of which enhances the synthesis, activity, and/or export of Phi. The function of this gene is not required for Phi production in transformed M4-80R, but such function may be necessary for Phi production or export in other bacterial host strains. DNA sequences for production of Phi encode catalytic proteins The enzymatic steps required for Phi synthesis in bacteria are unknown, but can be anticipated based on knowledge that the structure of Phi is consistent with synthesis via a polyketide mechanism (Figure 4). Similarities also are known to exist between fatty acid and polyketide synthases, β-ketoacyl synthases (FAS), thiolases, and polyketide synthases (PKS) in bacteria, and the stilbene and chalcone synthase (STS/CHS) enzymes from plants. Synthesis of both polyketides and fatty acids is known to initiate by condensation of an acetyl starter unit with malonyl-ACP; this step generally is catalyzed by a β-ketoacyl synthase separate from the one(s) that catalyze subsequent chain elongation via condensation reactions that sequentially add C 2 units from malonyl thioesters to the growing chain. In bacterial FAS, separate acetyl and malonyl transferases are required, as is a transferase for chain termination. PKS in Streptomyces resembles FAS in that ACP-linked residues are implicated as building units based on the presence in PKS loci of an ACP gene. A significant difference between CHS and the FAS and PKS β-ketoacyl synthases is that CHS requires neither ACP nor specific transferases; malonyl-CoA units are added to a coumaroyl-CoA starter unit. Based on these precedents, it is reasonable that Phi synthesis minimally will require a chain-initiating β-ketoacyl synthase; a malonyl condensing enzyme, and a cyclase for ring closure. Depending on the mechanism of transfer, and acyl carrier protein may also be required. Analysis of the protein sequences encoded by SEQ ID N0:1 and comparison to other protein sequences revealed conserved structural motifs and similarities to known proteins that are consistent with predicted functions in Phi biosynthesis via the polyketide pathway. Motifs conserved (mismatch-^l) within PhlA include the short chain alcohol dehydrogenase family signature, the ornithine/diaminopimelic acid/arginine decarboxylase family 2 signature, and a phosphopantetheine attachment site (Example 4). These motifs suggest that PhlA may function either in the provision of substrates for PhlD and/or as an acyl carrier. A partially conserved (mismatch=l) thiolase signature sequence within the PhlR protein sequence indicates similarity to type II thiolases that catalyze the thiolysis of acetoacetyl-coA and are involved in pathways such as poly-β-hydroxybutyrate synthesis and steroid biogenesis which resemble the Phi pathway (Figure 4) in their dependence on condensation reactions involving short-chain acyl thioesters. Analysis of the PhlC protein sequence and comparison to other protein sequences revealed significant similarity to the N- terminal portion of mammalian peroxisomal sterol carrier protein X (SCPx) (Example 4; Figure 5). This portion of SCPx has 3- oxoacyl-CoA thiolase activity, and is hypothesized to supply acetyl-CoA for anabolic reactions in cells well-supplied with energy. By analogy to SCPx, the PhlC product may provide a source of CoA starter units for the synthesis of Phi. Alternatively, because thiolases share conserved residues in their condensing domains with β-ketoacyl synthases and chalcone synthases, the similarity we have detected between PhlC and SCPx may indicate activity in chain elongation reactions analogous to those that occur in fatty acid and polyketide biosynthesis. PhlD is required for Phi production, and the PhlD protein revealed a highly significant similarity to members of the chalcone synthase/stilbene synthase (CHS/STS) family of enzymes from higher plants. PhlD contained regions with extensive similarity to the active site and signature sequence domains of CHS/STS enzymes (Example 4; Figure 6) but had surprisingly little similarity to prokaryotic β-ketoacyl synthases, including those that catalyze similar condensing reactions (e.g., polyketide synthesis by actinomycetes) in bacteria. It is, to our knowledge, the first prokaryotic protein to show such extensive similarity to the CHS/STS protein family. Acylphloroglucinols have been recovered as by-products of chalcone synthesis in vitro , suggesting that PhlD may be sufficient to catalyze the condensation and/or cyclization reactions required for synthesis of monoacetylphloroglucinol (Figure 4). Based on results from mutagenesis (Example 2), phenotypic characterization of transformants (Example 1) containing DNA fragments that confer or enhance Phi biosynthetic capability, and sequence analysis of the predicted protein sequences encoded within these fragments (Example 4), the segment of DNA containing phlACBD and phlR comprises the minimum known to date to be required for production of Phi. Contiguous sequences modulate Phi production Mutagenesis of pMON5122 with Tn3HoHol revealed a locus designated Red and located adjacent x.o those sequences present in SEQ ID NO:l. The Red locus was not itself required for Phi production, but M480-R(pMON5122) , containing certain mutations in Red were less inhibitory in vitro (Table 4). The Red locus therefore had the capacity to enhance Phi production or activity, perhaps by facilitating Phi export, in strains transformed with a DNA segment that includes phlACBD and phlR . The DNA sequences within the Red locus were found to contain an open reading frame encoding a protein designated PhlE with significant similarity to Staphylococcus aureus norA protein, which contributes to fluoroquinone resistance. NorA and other such proteins are members of a very large superfamily of transmembrane solute facilitators; among the most well-known representatives of the drug efflux subfamily are the tetracycline resistance proteins. PhlE retained conserved structural features of these integral membrane permeases (Figure 7), including a central hydrophilic loop bordered on either side by six hydrophobic -helices. The results of phenotypic analysis of mutations in the Red region, combined with knowledge of the predicted structure of the PhlE protein are consistent with PhlE functioning in the export of Phi. Such export would reduce the intracellular Phi concentration, and may represent a mechanism of resistance by which bacteria producing Phi avoid autointoxication. A seventh open reading frame designated phlF was identified upstream of and oriented divergently from phlABCDE. This open reading frame is present in truncated form in pPHL5122. The DNA sequences including phlABCDE, phlR , the intervening sequences (which are likely to contain promoters based on their position and AT-richness) and the truncated phlF gene are included in SEQ ID NO:4. In pPHL5122 this DNA fragment was capable of conferring or enhancing Phi production in all strains of Pseudomonas into which it was introduced (Example 1). The DNA sequence consisting of phlABCDE, phlR , the intervening sequences containing the putative promoter region, and the complete phlF gene are given in SEQ ID NO:3. The PhlF protein sequence was similar to those of tetracycline repressor protein, and other known repressors, particularly within a conserved helix-turn-helix domain (Figure 8) which is a characteristic feature of such DNA-binding repressors. It is known that the tetracycline repressor controls expression of the terR resistance gene, and that repressor gene deletions resulting in truncation of the carboxy-terminal end of the repressor protein can result in overexpression of the resistance protein. By analogy, the very high levels of Phi production by transformed derivatives of P. fluorescens Q69c-80 containing a construct consisting of the truncated phlF and the phlACBDE and phlR genes (Table 3) support the argument that the phlF gene is a repressor of phi gene expression. That pMON5120, containing an intact phlF gene, does not transfer Phi biosynthetic capability (Table 1) further strengthens the argument. Those skilled in the art will also be aware that it will be possible to improve the effectiveness of a Phi-producing biological control strain by modulating the level of expression or activity of that strain • s Phi biosynthetic genes. This can be accomplished by genetic manipulation of cloned genes such as phlE and phlF, followed by introduction into the genome. In strains that already produce Phi, the altered genes may be introduced to replace the native genes by homologous recombination, or may be introduced at a separate location. An example of the latter is the introduction by transposition (according to the method given in Example 1) of a heterologous promoter operably linked to the truncated phlF gene. The truncated PhlF protein competes with the intact protein, relieving the repression caused by the native protein and permitting increased Phi production. The level of competition, and hence, the level of Phi overproduction, is controlled by the strength of the heterologous promoter relative to the native phlF promoter. Such promoters are readily available to those skilled in the art, and a possible means of fusing them to genes such as the truncated phlF gene, involves the use of the overlap extension polymerase chain reaction strategy (Horton et al.. Gene 77:61 (1989)). Alternatively, the truncated phlF gene, under control of its native promoter or a heterologous promoter, is substituted by homologous recombination for the genomic phlF gene, again effecting increased Phi production. Another aspect of the invention is genetically engineered recombinant nucleic acid molecules, i.e., non-naturally occurring nucleic acid molecules, preferably DNA, containing a portion encoding a phi gene protein or a functional phi gene homolog, which has the function of conferring or enhancing Phi production in bacteria expressing phi genes or functional homologs thereof. A recombinant DNA molecule refers to a hybrid DNA sequence comprising at least two DNA sequences, the first sequence not normally being found together in nature with the second. Such molecules can be obtained by manipulation of genetic material using restriction enzymes, ligases, and similar recombinant techniques as described by, for example, Sambrook et al., (Molecular Cloning, second edition. Cold Spring Harbor Laboratory, Plainview, NY; (1989)), Ausubel et al.. Current Protocols in Molecular Biology, Current Protocols (1989), and DNA Cloning: A Practical Approach , Volumes I and II (ed. D. N. Glover) IREL Press, Oxford, 1985. Examples include recombinant vectors, such as cloning or expression vectors which contain DNA sequences encoding phi gene proteins which are in a 5' to 3' (sense) orientation or in a 3' to 5' (antisense) orientation. "Recombinant," as used in the present application, does not refer to naturally-occurring genetic recombinations. The recombinant DNA sequences of the present invention may originate from Pseudomonas or from organisms of a different taxonomic classification. The recombinant DNA sequences of the present invention may further comprise one or more regulatory DNA sequences operably linked to the structural DNA sequences above. Such regulatory sequences include promoter sequences, leader sequences, and other DNA sequences which may affect the expression of the regulatory DNA sequences, as well as those fragments of a regulator DNA sequence that are able to act with such effect. Bacterial regulatory elements known in the art include any bacterial regulatory element that is known to function as a promoter, enhancer, ribosome binding site, and/or any other regulatory control mechanism of the associated coding sequence. Bacterial regulatory elements include hybrid regulatory regions comprising mixtures of parts of regulatory elements from different sources. For example the trp-lac ( tac ) promoter combines the -35 region of the E. coli tryptophan operon with the -10 region of the E. coli lac operon promoter and functions effectively in Pseudomonas (Bagdasarian et al., Gene 26:273-282 (1983)). An associated coding DNA sequence is one that is adjacent or adjoining 3' to the regulatory elements and which codes for a protein when transcribed and translated. Bacterial regulatory elements can be isolated from commercially available vectors, bacterial regulatory elements known in the art, and bacterial regulatory elements identified by using promoterless marker- containing transposons or promoter selection vectors. As used herein, a nucleic acid molecule can be a DNA molecule, an RNA molecule or a DNA-RNA hybrid molecule. A non-naturally occurring nucleic acid molecule is one which does not occur in nature. A non-naturally-occurring nucleic acid molecule, includes, for example, DNA sequences, in isolated and purified form; a recombinant nucleic acid molecule having a heterologous region, that is, an identifiable segment of DNA that is not covalently linked to the Phi gene coding sequences in nature; or such a non-naturally occurring molecule may be constructed of parts which have been chemically synthesized; or a synthetic sequence having codons different than the native gene. Parts from heterologous sources may be joined by any means known to the art, e.g., by ligation in vitro. Alternatively, parts may be joined in an in vivo process such as by recombination, but such recombination will be directed by the hand of man and the desired result will be identified by man. The Use of Phi Sequences for Plant Pathogen Control It is an aspect of the present invention that improved biological control strains can be generated following the introduction of genes that confer Phi biosynthetic capability into a variety of bacterial isolates from nature. This approach represents a method for the generation of potentially effective biocontrol strains adapted to a variety of crop plants or ecosystems. It is a further aspect of the present invention that Phi- producing biological control strains can be rendered more effective by the introduction of genes described herein that enhance Phi biosynthetic capability. In another embodiment of the present invention, biocontrol agents are provided which are able to inhibit the growth of fungal pathogens, such as Gaeumannomyces gra inis , Rhizoctonia solani , and species of the genera Pythium and Fusarium. These biocontrol agents may be bacteria, plant cells or animal cells transformed with the recombinant DNA sequences above, but are preferably bacterial strains, and more preferably Gram negative bacteria, such as those of the genus Pseudomonas . Most preferred as biocontrol agents are strains of the species Pseudomonas fluorescens. Another embodiment of the present invention provides methods of inhibiting the growth of fungal pathogens, such as Gaeumannomyces graminis , Rhizoctonia solani , and species of the genera Pythium and Fusarium. In the methods of the present invention, the DNA sequences that confer or enhance Phi production can be introduced into the genome of a bacterial strain which may not ordinarily be effective as an inhibitor of fungal pathogens, resulting in an effective biocontrol strain. DNA in the form of plasmids can be transferred from one bacterium to another by a sexual process termed conjugation. Plasmids that mediate conjugal transfer contain genes that code for the synthesis of pili. These pili are hollow filaments that join the plasmid-bearing (donor) bacterium with another bacterium (recipient), and through which replicated copies of the plasmid pass from the donor to the recipient. This procedure occurs naturally and is utilized in the laboratory as a method of transferring genes between bacteria. For some strains of Pseudomonas , conjugal transfer is the preferred method of transfer because these bacteria are not readily transformed with isolated and purified DNA. Most of the plasmids commonly used as vectors for conjugal transfer in the laboratory do not themselves cause conjugation, but are transmissible and can be mobilized when conjugation is mediated by a coresident conjugative plasmid. Transmissible plasmids may have a broad host range (i.e., able to replicate in a variety of bacterial hosts) or a narrow host range (i.e., replication is limited to E. coli ) . Examples of broad host range transmissible plasmids suitable for genetic analysis in Gram- negative soil bacteria are provided in Transformation of Plants and Soil Microorganisms, K. Wang, A. Herrero-Estrella, and M. Van Montagu, Eds., Cambridge University Press, Cambridge (1995). Broad host range transmissible plasmids may be stably maintained in Pseudomonas in the absence of selection (e.g., pPHL5122) or more usually maintained only in the presence of an antibiotic, resistance to which is encoded on the plasmid (e.g., pMON5122). Plasmids that are stably maintained under selection are suitable as vectors in vitro (Tables 1 and 2), but are unacceptable when the cloned DNA they carry must be functionally evaluated in an environment such as soil where it is not possible to maintain continuous antibiotic selection. Stably maintained transmissible plasmids are appropriate for use as vectors under contained conditions such as the growth chamber where persistence of the plasmid in the host is desired, and there is no danger of gene escape into the environment (Table 5). Bacteria harboring transmissible vectors containing cloned DNA may not be released into natural environments, however, because the possibility exists for uncontrolled mobilization of recombinant DNA mediated by conjugative plasmids indigenous to native soil microorganisms. Stable insertion of cloned phi genes into bacterial strains in a manner suitable for environmental release may be accomplished by homologous recombination or by transposition. When mediated by recombination, a selectable marker is first introduced into or adjacent to the Phi DNA in such a way that phi gene functions are not disrupted. The marked phi genes are cloned into a fragment of chromosomal DNA containing the target site of insertion such that the sequences containing the marker gene and the phi genes are flanked on either side by target site sequences of no less than 500 bp, and preferrably of at least 1 kb. The entire recombinant fragment is introduced into the target strain on a transmissible plasmid, and transformants are selected that retain the Phi gene marker, but not that of the vector. Transposons provide an alternative means to the generation of stable chromosomal insertions. Sequences containing phi genes are cloned within a transposable element which contains a selectable marker and is carried on a transmissible plasmid. Transposition functions are provided by genes encoded on a plasmid not maintained in the target strain; this may be the plasmid carrying the transposable element (Herrero et al., J. Bacteriol . 172:6557- 6567 (1990); de Lorenzo et al., supra) or a separate plasmid (Barry, Gene 71:75-84 (1988)). The construction of a transposable element containing phi genes is described in Example 1, and an example of its use in in situ assessment of phi gene activity is given in Example 8. In another embodiment of the present invention, methods are provided for producing Phi which is effective in inhibiting the growth of fungal pathogens including Gaeumannomyces graminis, Rhizoctonia solani , and species of the genera Pythium and Fusarium. This method comprises introducing the recombinant sequences of the present invention into the genome of of a bacterium, allowing the transformed bacteria to produce Phi, and extracting the antibiotic from cultures of the transformed agent. The present invention encompasses the preparation of antifungal formulations in which one or more transformed bacterial strains is used as an active ingredient. The present invention further encompasses the preparation of antifungal formulations in which the active ingredient is Phi produced by the transformed bacterial agent of the present invention. Formulations in which the active ingredient is a bacterial biocontrol agent or the antibiotic Phi produced by such agent may be applied in any manner known for seed and soil treatment with such preparations. Other uses To identify phi genes from other bacterial species, preferably species of the genus Pseudomonas , genomic DNA from a culture of the bacteria is isolated as described below. The isolated DNA is cut with one or more restriction enzymes, cloned in an appropriate vector such as a cosmid vector to generate a library, and DNA from colonies containing clones from the library is blotted onto a nylon membrane such as Nytran. The blots are probed with an oligonucleotide probe containing a phi gene or portion thereof greater than 9 nucleic acids in length, and preferably greater than about 18 nucleic acids in length. Probes to specific structural features of the Phi proteins are preferred as they provide a means to isolate phi genes with similar structural domains. Most preferred are probes including the catalytic and signature domains of phlD, which is required for production of Phi. Probes may be based on the sequence of either strand of the DNA comprising the motif, and can be degenerate (i.e., a mixture of all possible coding sequences for a given amino acid sequence). General methods for designing and preparing such probes are provided, for example, in Ausubel et al., supra, and Guide to Molecular Cloning Techniques, 1987, S. L. Berger and A. R. Kimmel, eds.. Academic Press, New York. These oligonucleotides are useful for phi gene isolation, either through their use as probes capable of hybridizing to phi complementary sequences or as primers for various polymerase chain reaction cloning strategies. Hybridization procedures and techniques are well known to those skilled in the art and are described in Ausubel, supra, and in Guide to Molecular Cloning Techniques , 1987, S. L. Berger and A. R. Kimmel, eds.. Academic Press, New York. If desired, a mixture of different oligonucleotide probes may be used for the screening of the recombinant library. Conditions of high stringency for detecting a phi gene include hybridization at about 42°C and about 50% formamide; and sequential washes at 65°C in 2X SSC-1% SDS and 0.1 X SSC. Lower stringency conditions can be achieved by one or more of the following: hybrdiziation at 42°C without formamide, washing at 42°C, and washing in 6X SSC-1% SDS followed by 6X SSC-0.1% SDS. Oligonucleotides derived from phi gene sequences can also be used as primers in PCR cloning strategies. PCR methods are well known in the art and described, for example, in PCR Technology, H. A. Erlich, ed., Stockton Press, London, 1989; PCR Protocols: A Guide to Methods and Applications , M. A. Innes, D. H. Gelfand, J. J. Snitsky, and T. J. White, eds. (1990), and Ausubel et al., supra. P. fluorescens contains one genomic region encoding Phi proteins. The conserved regions in the phi genes are useful in the design of primers to mediate the recovery of functional phi homolog genes in other bacteria, particularly members of the genus Pseudomonas . Such primers are designed to amplify only sequences flanked by the oligonucleotides in genes having sequence identity to phi genes. Once a clone encoding a putative phi gene is identified, it is then determined whether the candidate gene is capable of producing a functional Phi homolog protein. A functional Phi homolog protein is one encoded by DNA from a source other than P. fluorescens Q2-87 which can, when substituted for the homologous phi gene protein from strain Q2-87, function in place of that Q2- 87 phi gene protein. Assays based on the functional substitution of one protein for another are termed complementation assays and, in bacteria, generally are conducted in a strain in which the gene to be complemented is inactived by mutation, and the gene to be tested for complementation activity is introduced on a plasmid. Thus, in Table 1 the mutant Q2-87::Tn5-l was complemented with the plasmid pMON5122, and in Example 7, Q2-87::Tn5-l was not complemented with a BamHI-C2aI fragment from phlD. The availability of the P. fluorescens nucleic acid molecules encoding phi gene proteins makes accessible phi gene sequences encoding phi gene proteins or functional homologs from other bacterial strains. The phi gene sequences or portions thereof are used as oligonucleotide probes to hybridize to the additional genomic sequences by hybridization under standard conditions. Sequences which hybridize specifically to a phi gene coding sequence or its complement and which encode a Phi functional homolog protein are encompassed by the invention. Such oligonucleotides are prepared by standard methods and assembled by procedures known to those in the art. The length of the probe employed must be sufficient to hybridize to homologous regions of DNA wherein hybridization is due to at least about 70% homology, as opposed to nonspecific binding. It is well known in the biological arts that certain amino acid substitutions can be made in protein sequences without affecting the function of the protein. Generally, conservative animo acid substitutions or substitutions of similar amino acids are tolerated without affecting protein function. Similar amino acids can be those that are similar in size and/or charge properties, for example, aspartate and glutamate and isoleucine and valine are both pairs of similar amino acids. Si ilarity between amino acid pairs has been assessed in the art in a number of ways. For example, Dayhoff et al. (1978) in Atlas of Protein Sequence and Structure , Vol. 5, Supplement 3, Chapter 22, pages 345-352, which is incorporated by reference herein, provides frequency tables for amino acid substitutions which can be employed as a measure of amino acid similarity. Dayhoff's frequency tables are based on comparisons of amino acid sequences for proteins having the same function from a variety of evolutionarily different sources. The amino acid sequence of the protein may or may not be identical with the amino acid sequence which occurs naturally in bacteria. The identity of phi genes can be confirmed by their ability to produce a functional Phi homolog protein as defined above. In addition, artificially induced mutations can be included so long as they do not destroy activity. A "mutated Phi protein" refers to protein which has the same activity as its unmutated predecessor, but which is derived by mutation of a DNA encoding a Phi protein. By "derived from mutation" is meant both direct physical derivation from a DNA encoding the starting material Phi gene protein using, for example, site specific mutagenesis or indirect derivation by synthesis of DNA having a sequence related to, but deliberately different from, that of the Phi gene. As means for constructing oligonucleotides of the required length are available, such DNAs can be constructed wholly or partially from their individual constituent nucleotides. Genetically engineered means that the result has been directed by the hand of man. A bacterium genetically engineered to contain a particular DNA molecule is one into which the DNA has been introduced by any means known to the art, including but not limited to transformation, conjugation, electroporation, particle bombardment, and the like. A genetically engineered nucleic acid molecule, such as a genetically engineered DNA molecule, is one which is the product of molecular biological process including but not limited to DNA ligation, in vitro mutagenesis or the like. The DNA sequences of the invention are useful to prepare DNA expression molecules by cloning the sequence in any suitable expression vector that is capable of introducing a foreign gene into a heterologous bacterial host. The recombinant vector is constructed so that the coding sequence is located in the vector with the appropriate control sequence and operationally associated therewith, that is, the positioning and orientation of the phi gene DNA coding sequence with respect to the control sequences is such that the coding sequence is transcribed under the control of the control sequences (i.e., by RNA polymerase which attaches to the DNA molecule at the control sequences). The control sequences may be ligated to the coding sequence prior to insertion into a vector. Alternatively, the coding sequence can be cloned directly into an expression vector which already contains the control sequence and an appropriate restriction site downstream from the control sequence. The vector should be selected so as to have a promoter operable in the host cell into which the vector is to be inserted (that is, the promoter should be recognized by the RNA polymerase of the host cell). In addition, the vector should have a region which codes for a ribosome binding site positioned between the promoter and the site at which the DNA sequence is inserted so as to be operatively associated with the phi gene coding sequence once inserted. The vector should be selected to provide a region which codes for a ribosomal binding site recognized by the ribosomes of the host cell into which the vector is to be inserted.

The genetic region that carries all the information necessary to direct Phi biosynthesis is identified by cloning DNA segments from a Phi-producing strain such as Q2-87 into a suitable broad host range vector such as pRK415 (carries a tetracycline resistance marker) that can be maintained in transformed Pseudomonas strains, and introducing the cloned DNA segments into a rifampicin-resistant mutant of the Phl-nonproducer P. fluorescens M4-80R via a triparental mating (Thomashow and Weller, J. Baσteriol. 170:3499-3508 (1988). The transformed derivatives were then screened for (1) the presence of a soluble red pigment, the presence of which is correlated with production of Phi; (2) the ability to inhibit in vitro the growth of the indicator bacterium Clavibacter michiganensis subsp. michiganensis ; and (3) production of Phi as determined directly by extraction and analysis by thin layer chromatography. For triparental matings, overnight cultures (in 5 ml LB with appropriate antibiotic selection) of the donor Escherichia coli strain DH5 carrying plasmids with inserted Q2-87 DNA, and the helper E. coli strain HB101 (pRK2013) (provides functions required for DNA transfer by bacterial conjugation) were centrifuged and resuspended in 500 μl of fresh LB broth. 25 μl of each of these cultures was spotted onto Millipore filter papers (1cm 2 ) and mixed; after incubation for 2 hours at 37° C, 30 μl of the recipient strain P. fluorescens M4-80R, (10ml LB culture grown overnight at 28° C, centrifuged, and resuspended as above) was added. Filters were incubated overnight at 28° C and the resulting cell mass was resuspended in 1 ml of sterile distilled water. Aliquots of 200 μl of this suspension were spread on LB plates containing rifampicin and tetracycline. Rifampicin and tetracycline resistant transformants obtained from triparental matings were evaluated for production of red pigment visually after growth on Yeast Malt (YM) broth or King's Medium B (King, et. al., J. Lab. Clin . Med. 44:301-307 (1954)), after incubation at 28°C for 4 to 7 days. A spontaneous, tetracycline-resistant mutant of Clavibacter michiganensis subsp. michiganensis was used to assess inhibition in vitro. Inhibition of C. m . michiganensis by Phi was ana yzed as follows: 100 μl of a 48-hour old-culture of the indicator organism in water agar (3ml) was overlayed on YM plates with appropriate antibiotic. These plates were incubated for 4 to 6 h to let the agar solidify and allow initial growth of C. m. michiganensis . Strains to be tested for Phi production were spotted onto these plates using a toothpick. Strains were assayed in sets of three per plate and each set was analyzed in triplicate. Each plate also included the positive control strain M4-80R (pMON5122) and the negative control strain, M4-80R (pRK415). The diameter of the zones of inhibition was measured after two to four days and the values were compared statistically among sets by an analysis of variance (ANOVA) ; the set means were compared by a least significant different test (LSD) when significant differences among sets was indicated by the ANOVA (Fisher's protected LSD). For extraction of Phi and monoaσetylphloroglucinol (MAPG) , a possible Phi precursor, cultures were grown for 4 to 7 days either in liquid YM medium or on YM plates. The cells were removed by centrifugation and the antibiotic was extracted from the cell pellet as described by Keel et al. (1992) except that the final extract was dissolved in 100% methanol. The samples were chromatographed on Uniplate™ Silica Gel GHLF TLC plates (Alltech Associates Inc. Deerfield, II) in a solvent system of chloroform:acetone 9:1 (v/v) . Spots were visualized by UV absorption at 254nm. For example, the plasmid pMON5118 and its deletion derivatives, described by Vincent et al. (Appl. Environ. Microbiol. 57:2928-2934 (1991), were introduced into P . fluorescens strain M4-80R by triparental mating. Strain M4-80R carrying any of the plasmids pMON5116, pMON5117, pMON5118, pMON5120 and pMON5123 did not produce the red pigment and did not inhibit C. m. michiganensis . Neither Phi nor MAPG could be isolated from any of these strains. On the other hand, strain M4-80R (pMON5122) showed red pigment production, inhibited C. m . michiganensis , and both Phi and MAPG were isolated from broth as well as agar cultures of this strain (Table 1). Thus, only plasmid pMON5122 was able to transfer Phi biosynthetic capability to strain M4-80R. The fact that larger fragments (pMON5120, pMON5118 and pMON5117) carrying DNA sequences flanking the fragment in pMON5122 were unable to transfer Phi synthesis may indicate that they carry negative regulator sequences. Table 1 Plasmids Q2-87::Tn5 M480R Phi Red HCN Phi Red HCN pigment pigment __________ _ _ _ _ _ _ pMON5117 + 3 5 - 0 0 pMON5120 + 3 5 - 0 0 -P- pMON5122 + 4 5 + 4 0 pMON5123 + N.D. 5 - 0 0 B. To determine whether the fragment from pMON5122 was able to confer or enhance Phi biosynthetic capability in a wide range of P. fluorescens strains, it was cloned as a Hindlll-EcoRI fragment into pVSP41, a plasmid that can be maintained in Pseudomonas strains without antibiotic selection. This construction, called pPHL5122, was introduced into 6 Pseudomonas strains by triparental matings as described above, and the production of Phi by the transformed strains was assessed by production of red pigment and extraction of Phi from broth cultures as described above. Plasmid pPHL5122 directed Phi synthesis in all of the six transformed recipients. Strains that did not already produce Phi acquired ability to produce the antibiotic. Strains that already produced Phi, i.e., Q2-87, showed an increase in antibiotic production (e.g. Q2-87(pPHL5122) , Table 2). pPHL5122 also transferred Phi biosynthetic capability to seven other Phi nonproducing recipient strains into which it was introduced as indicated by the presence of the red pigment. Thus, pPHL5122 conferred or enhanced Phi biosynthesis in all strains into which it was introduced. To determine whether the locus contained on pMON5122 specifically directed Phi production, or if it also affected the production of other secondary metabolites as would be expected of a global regulatory gene, HCN production was assayed in Q2-87, Q2-87::Tn5 (a mutant described by Vincent et al. with a Tn5 transposon that inactivates the genomic homologue of the genes cloned in pPHL5122), and the seven transconjugant derivative strains into which pPHL5122 (or pMON5122) was introduced. Strains were grown on modified KMB medium containing 4.4g/L glycine (Pierson and Thomashow, Mol . Plant-Microbe Interact . 5:330-339 (1992)). HCN indicator paper was taped to the lid of the plates and the plates were sealed with Parafilm and incubated for 2 to 4 days at 28° C. HCN indicator paper was prepared by soaking Whatmann 3MM filter paper in a solution of 2% sodium carbonate and 0.5% picric acid and air drying. HCN production was detected by the yellow to red color change of the indicator paper. P . fluorescens strain CHAO, which produces copious amounts of HCN, was used as positive control and strain M4R-80, which does not produce HClv was included as a negative control. Four of the recipient strains (M4-80R, M7z-80, Q26a-80, and Q29z-80) did not produce HCN, whereas three others (M23dz-80, Q69c-80R2, and Q2-87) were HCN + (Table 2). Both Q2-87 and Q2- 87::Tn5 produced similar amounts of HCN as detected by the conversion of the yellow HCN indicator paper to red color, indicating that the Tn5 insertion specifically inactivated production of Phi. Further, HCN production was not coordinately transferred with Phi biosynthesis in the HCN-nonproducing strains upon introduction of pPHL5122, nor was the amount of HCN produced by strain M23dz-80 detectably changed by plasmid pPHL5122. However, HCN production was slightly reduced in Q69c-80 (pVSP 41) and Q69c-80 (pPHL5122) and markedly lessened in Q2-87 (pPHL5122) (Table 2). As expected, pPHL5122 also conferred the Red phenotype characteristic of Phi biosynthesis; otherwise, the appearance of the transgenic strains was unchanged. These results indicate that the fragment contained on pPHL5122 does not mediate global activation of genes involved in secondary metabolism. -*J C. We have used the mini-transposon vector pUT mini-Tn5 Km described by de Lorenzo, et al., supra, to introduce Phi biosynthetic genes from pMON5122 into the chromosomes of rhizosphere pseudomonads including strains Q69c-80, Q65c-80, and the PCA-producing strains 2-79 and 30-84. The findIII-£coRI fragment from pMON5122 was cloned into the plasmid vector pUCNotl such that NotI restriction sites were added at either end of the fragment, and the fragment was then excised by digestion with NotI and ligated into the NotI site in the vector pUT::Km. This site is located between two IS-terminal sequences that also flank a transposable miniTn5 element carrying a kanamycin resistance gene, and pUT::Km also carries a transposase gene adjacent to but outside of the mobile DΝA segment (Herrero et al, J. Bacteriol . 172:6557-6567 (1990)). The resulting plasmid, pUT::Km-Phl, can only replicate in bacterial strains that provide an R6K-specified π protein not produced by recipient strains of Pseudomonas . Transfer of the plasmid pUT::Km-Phl from the donor strain E. coli S17-lλpir, into the Pseudomonas recipient strains Q69c-80, Q65c-80, 2-79 and 30-84 was by conjugation. The donor strain, which provides the necessary conjugation factors, was grown overnight with shaking at 37° C in 5 ml of LB broth amended with ampicillin and kanamycin (each 100 μg/ml) . Each rifampicin- resistant recipient pseudomonad was grown overnight in 5 ml of LB broth without antibiotics. The cultures were centrifuged at 6,000 rpm for 5 min and resuspended in 1 ml of fresh LB broth. For each recipient strain, thirty μl of the donor was spotted onto a membrane filter placed on an LB plate, and then 20 μl of cell suspension of one recipient strain was added and the two were mixed. These plates were incubated at 27° C overnight, and then the bacterial growth on each filter was suspended in 1 ml of sterile distilled water, centrifuged, and resuspended in 1 ml of sterile distilled water. The washed cells were diluted 10-fold, and 100 μl of each dilution was plated on M9 minimal medium (0.3 g KH 2 P0 4 , 0.5 g sodium chloride, 1.0 g ammonium chloride, 1 ml calcium chloride (50 mM), 1 ml MgS0 4 '7H 2 0 (1 M) ) amended with 100 μg/ml of kanamycin (MΘ^ K ...) and incubated at 27 ° C for 3 days. By selecting for kanamycin-resistant transconjugants from this mating, strains were obtained in which the mini-Tn5 element containing phi genes and the kanamycin resistance gene had transposed into the Pseudomonas genome. Twenty kanamycin-resistant transposition derivatives of Q69c- 80 have been evaluated for the presence of phi genes and for Phi production. Strain Q69c-80: :mTn5PHL20 was deposited under terms of the Budapest Treaty June 21, 1995, in the Agricultural Research Culture Collection (NRRL), 1815 North University Street, Peoria, Illinois, and has been assigned accession number NRRL B-21474. Southern blot analysis (Photogene Nucleic Acid Detection System, BRL®, Life Technologies, Inc., Gaitherburg, MD 20898, USA) was carried out to confirm insertion of the Phi biosynthetic locus and reveal the insertion pattern of the locus on the chromosome of P. fluorescens Q69c-80. For Southern hybridization, genomic DNA was prepared as described by Ausubel et al., supra. Cultures were grown overnight in 1.5 ml of LB broth, the bacterial cells were centrifuged and resuspended in a lysis solution (561 μl T^E- t buffer, 15 μl of 20% SDS, and 12 μl of 5 mg/ml Pronase®) and incubated at 37°C for 1 h. One hundred two microliters of 5 M NaCl was added and mixed thoroughly. Eighty microliters of CTAB/NaCl solution was added and mixed, and the suspension was incubated at 65 ° C for 10 min. The DNA was extracted sequentially with equal volumes of phenol/chloroform/isoamyl alcohol (25:24:1) and with chloroform /isoamyl alcohol (24:1). The DNA was precipitated with 60% volume of isopropanol and washed with 70% ethanol before resuspending in T^ j buffer. Genomic DNA from each of the 20 derivatives was digested with Sail (first experiment) or I?σoRV (second experiment). Digested DNA was separated by electrophoresis on a 0.7% agarose gel, and transferred and bound to a nylon membrane (Magnagraph®, Micron Separations Inc., Westboro, MA 01581, USA) by known methods. Eight hundred microliters (5 mg/ml) of salmon sperm DNA (Sigma, St. Louis, MO 63178, USA) was boiled for 10 min and diluted into 40 ml of hybridization solution (lx HPB, 1% SDS). The membrane and the hybridization solution were introduced into a sealable plastic bag and incubated for 2 to 4 h at 65°C. A DNA probe consisting of the excised and purified fragment from pMON5122 labeled as directed by the manufacturer with the BioNick Labeling System (Gibco BRL, Life Technologies, Inc., Gaitherburg, MD 20898, USA) was boiled for 10 min, added to the plastic bag, and incubated overnight at 65 * C. After hybridization, the membrane was washed twice in 100 ml of a solution (5x SSC, 0.5% SDS) at 65° C for 5 min per wash, once with 100 ml of a solution (O.lx SSC, 1% SDS) at 65° C for 30 min, once in 100 ml of 2x SSC at room temperature for 5 min, and then incubated in 100 ml of blocking solution (Tris-buffered saline (TBS)-Tween 20, 3% BSA) for 1 h at 65° C. Seven microliters of streptavidin-alkaline phosphatase (SA-AP) was diluted into 7 ml of TBS-Tween 20 (1:1000 dilution) , and the resultant solution was poured on the membrane and incubated at room temperature for 10 min with repeated pipetting. The membrane was washed twice in 100 ml of TBS-Tween 20 at room temperature for 15 min each time and in 100 ml of the BRL final wash buffer at room temperature for 1 h. The membrane was briefly blotted to remove excess liquid and placed on a plastic development sheet. One milliliter of the development reagent was dropped near the membrane on the plastic development sheet and immediately covered with another plastic sheet to spread the reagent evenly under conditions of reduced light. After 30 min, a piece of film was placed over the membrane, exposed for 2-4 h and developed. Results from Southern hybridization indicated that single copies of the Phi genes had transposed to unique sites in the individual derivatives. All of the derivatives initially produced Phi in vitro as indicated by the presence of the soluble red pigment described above. Phi production was quantified by using High Pressure Liquid Chromatography (HPLC). Pseudomonads were grown with shaking (200 rpm) in 15 ml culture tubes with 4.0 ml yeast malt broth for 60 h at room temperature. Cultures were acidified with 125 μl of 3.0 N HC1, and extracted twice with 10 ml ethyl acetate (90% extraction efficiency) . The organic phase contained Phi and MAPG and was evaporated to dryness and suspended in 3.0 ml of 35% (v/v) of acetonitrile (ACN) ;water both containing 0.1% trifluoroacetic acid (TFA) . Crude extracts were filtered through 0.20 μm syringe filters, followed by C-18 reverse phase HPLC (Waters NOVA-PAK C-18 Radial-PAK cartridge, 4μm, 8 x 100 mm) . The Waters HPLC system consisted of a 710B WISP, 510 pumps, and 680 automated gradient controller, with a 990 photo-diode array detector. HPLC solvent conditions were at a flow rate of 1.0 ml/min, with a 2 min initial condition at 10% ACN/water/0.1%TFA, followed by a 20 min linear gradient to 100% ACN/0.1% TFA. HPLC gradient profiles were monitored at the spectral peak maxima characteristic for Phi in the designated solvent system (270 nm, 330 nm) . Phi eluted at a retention time of 17.02 min at approximately 78% ACN/0.1% TFA. Standard curves were run using complementary Phl-nonproducing strains, where cultures spiked with known concentrations of standard were subjected to the same extraction procedure described above. Seven point, extracted, standard curves were completely linear and reproducible yielding correlation coefficients ranging from 0.9997-0.9994.

Quantities of Phi sometimes were over twenty-fold greater than produced by Q69c-80(pPHL5122) , and Phi usually was not detectable in cultures of strain Q2-87 grown under comparable conditions (data not shown) . These results suggest that expression of the transposed genes is deregulated, a hypothesis supported by DNA sequence data indicating that phlF, a putative repressor of Phi synthesis, is truncated and probably unable to repress phi gene expression in constructs containing the sequences shown in SEQ ID NO:4. Example 2. Generation and characterization of mutants to delineate the size of the fragment capable of conferring Phi biosynthetic capability. A restriction map of the DNA fragment cloned into pMON5122 was generated using the following restriction enzymes: BamHI, BstEII, Clal, UcoRI, EcoRV, Hindlll, PstI, PvuII, and Sa2l. This map revealed the cloned fragment to be 6.5 kb in size, and thus substantially smaller than the 9.5 kb value that was reported by Vincent et. al., supra. The relative positions of restriction sites were, however, sufficiently similar to those reported by Vincent et al. to suggest that Vincent's size estimate was in error, rather than that the maps were of two entirely different DNA segments. That portion of the cloned fragment that is necessary to direct Phi biosynthesis was determined by mutating pMON5122 with the transposon Tn3HoHol (Stachel et. al.. The EMBO J. 4:891-898 (1985)). Insertions of TnJHoHol were obtained by transforming E. coli strain HBl01(pHoHo/pSShe) with pMON5122. Transformants containing all three plasmids were subsequently mated with E. coli containing the conjugal helper plasmid pRK2013 and E. coli C2110, a nalidixic acid-resistant, po2A-deficient recipient strain which does not support replication of pHoHo and pSShe. Donor, helper and recipient strains were spotted onto Millipore filters (1cm 2 ) and incubated at 37° C for 6 hours. The growth on the filters was suspended in 1 ml of sterile distilled water and 200 μl of this suspension was spread on LB agar containing tetracycline (to select for pMON5122), ampicillin (to select for those plasmids containing the transposed Tn3HoHol element) and nalidixic acid (selects strain C2110). Transconjugants resistant to all three antibiotics were isolated in 18 sets of 48 on a grid. The site and orientation of insertion of the transposon in each pMON5122 derivative was analyzed by digestion of isolated plasmid DNA with i.σoRI, and in triple digests with -Jindlll, BamHI and i?σoRI. Of 846 mutants that were analyzed, 19% contained transposon insertions within the cloned fragment. Duplicate insertions giving rise to identical restriction fragments were obtained with high frequency in the left half of the fragment, whereas few insertions were obtained within the right end. In all, 43 unique insertions were analyzed further. Those plasmids containing insertions within the cloned fragment then were introduced by triparental mating into M4-80R and tested for the ability to direct Phi biosynthesis by TLC and by the C. michiganensis subsp. michiganensis inhibition bioassay described in Example 1. The bioassay method (detection limit 250 ng) was more sensitive than TLC (detection limit about 1 μg) and therefore was chosen for evaluation of the effect of the various insertions on Phi synthesis by strain M4-80R carrying the mutated plasmids. In Table 4, the value given for each insertion represents the percent decrease or increase in the size of the zone of inhibition on bioassay plates, relative to the positive control strain M4- 80R(pMON5122) within one assay set. An assay set consisted of positive and negative controls and three different insertion derivatives of M4-80R(pMON5122) . For each insertion, statistical comparisons were made only within assay sets by analysis of variance and Fisher's protected least significant difference test at p=0.05. ** indicates not significantly different from the positive control within the same assay set. * indicates % reduction of inhibition was intermediate between the positive and negative control (p=0.05) and the phenotype was Red " . M represents the average value for the negative control across all assay sets.

Insertion derivatives 8 and 9, which map to approximately the same site but contain Tn3HoHol in opposite orientations, enabled levels of C. m. michiganensis inhibition that were not significantly different from those of M4- 80R(pMON5122) , the positive control. Insertion derivative 8 was, however, Lac + indicating no break in transcription. Insertion derivatives 34 through 39 at the left end of the fragment shown in Fig. 2 were not significantly less inhibitory than the positive control. Thus, only the sequences within the 5-kb region at the right end of the fragment were required for inhibition of the indicator organism and for production of Phi. Strain M4-80R containing the various pMON5122: :Tn3 HoHol derivatives also was evaluated visually for the presence of the red pigment after 4-7 days in YM broth or on KMB agar plates. Whereas all insertions up to and including number 18 that were Phi were also Red , insertions downstream of number 18 exhibited other phenotypes. Most of these insertions had no effect on the presence of the red indicator pigment. However, insertion derivatives 20, 25, and 33 were Red " and had a level of inhibition of C. m. michiganensis intermediate between the positive and negative controls (Figure 2, Table 4). The region encompassing these insertions was therefore designated "Red" in Figures 1, 2, and 3. While not required for Phi production, it clearly is involved in Phi production or activity. Example 3. Determination of size, orientation and number of potential transcriptional units within the fragment required for Phi biosynthesis. The M4-80R(pMON5122: :Tn3HoHol) derivatives described in Example 2 were evaluated for expression of the lacZ gene carried on the transposon Tn3HoHol to determine the presence, number, size, and orientation of the transcriptional units within the mutated sequences. Expression of the lacZ gene in each derivative was detected by the development of blue colored colonies on LB medium containing 5-bromo-4-chloro-3-indolyl-β-D-galactoside (X- gal) . Results of this analysis are indicated in Figure 2. In strain M4-80R, all insertions which resulted in expression of lacZ, except three, were oriented in the same direction; only the Lac + insertions 2 and 3 at the right end and insertion 38 at the left end of the locus were oriented in the opposite direction. These results indicate the presence of at least two divergent transcriptional units. The long unit running from right to left continues past the region strictly necessary for the biosynthesis of Phi and into the Red region. The smaller unit running from left to right also extends beyond the fragment present in pMON5122. Reporter derivative strains of Q2-87: :Tn3HoHol-15 and Q2-87: :Tn3HoHol-40 were generated by introducing two of the Tn3HoHol insertions (15 and 40) into the Q2-87 chromosome by a process called marker exchange, which occurs due to spontaneous recombination between the sequences on the plasmid flanking the Tn3HoHol insertion and homologous sequences in the chromosome. In practice, such process is directed by the hand of man and the desired result is identified by man. Strain M4-80R carrying pMON5122: :Tn3HoHol derivatives 15 and 40 were inoculated into LB broth without tetracycline; after incubation overnight at room temperature, 100 μl of the culture was transferred to fresh LB broth. After a second such transfer, serial dilutions of the culture were prepared and 200 μl of each was plated on LB agar containing (X-gal). Cells in which homologous recombination had taken place gave rise to blue colonies, and could no longer grow on LB agar containing tetracycline. The reporter lacZ gene introduced into Phi locus in the chromosome of Q2-87 provides a simple means of monitoring Phi gene expression either visually, as colony color on LB agar containing X-gal, or quantitatively, with a β-galactosidase assay readily accessible to those in the art. Example 4. Analysis of the region including the Phi biosynthetic genes. Figure 1 depicts the genetic organization of the 7-kb region which encompasses the entire region known to be involved in Phi production. A variety of subclones were prepared as double- stranded templates for automated sequencing by digestion of the 6.5-kb fragment from pMON5122 with various restriction endonucleases, either singly or in combination, followed by ligation with the cloning vector pIC19H (Marsh, et. al.. Gene 32:481-485 (1984)) (Figure 3). A fragment of DNA which overlaps the right end of the pMON5122 fragment also was cloned from pMON5120 to determine the end point of phlF (Figure 3). Sequences were determined at the Nucleic Acid Research Facility at Iowa State University with an ABI automated sequencer. Sequence analysis was performed with the University of Wisconsin Genetics Computer Group (GCG) software (Staden, et. al.. Program Manual for the GCG package. Version 7.2 (Incremental Release - Documentation Updates), October 1992, 575 Science Drive, Madison, Wisconsin, USA 53711 (1992)). The program MAP was used to predict potential open reading frames in the sequence which was further supported by the results of the program CODONPREFERENCE using the Pseudomonas codon preference table. The program TRANSLATE was used to translate the open reading frames into protein sequences. The coordinates of the open reading frames in SEQ ID NO:3 are as follows: transcribed from right to left transcribed from right to left transcribed from right to left transcribed from right to left transcribed from right to left transcribed from left to right transcribed from left to right The coordinates of the truncated phlF open reading frame in SEQ ID NO:4 are as follows: phlF (truncated) 5781-6170; transcribed from left to right Protein sequences were compared to known proteins from all organisms within the NCBI database using the program BLAST (Altschul et. al., J. Mol . Biol . 215:403-410 (1990)). The predicted proteins were analyzed for the presence of characteristic sequence motifs using the program MOTIFS and the PROSITE database (Bairoch, Nucleic Acids Res . 19:2241-2245 (1991)). This analysis has led so far to the genetic organization of the fragment shown in Figure 1 as well as potential functions for some of the predicted proteins. The significance of the similarity of a predicted protein to known proteins is determined by calculating the binary comparison score (Z-score), which is measured in standard deviations. To have significant similarity the score must be 3 or greater. A value of 6 or greater corresponds to a probability of about 10" 9 that the degree of similarity seen in the two sequences arose by chance. Values in this range suggest a common origin by divergent evolution but do not rule out convergent evolution. When a score is greater than 9 the degree of similarity is considered to be too great to have arisen by chance or for the proteins to have evolved convergently so the sequences are considered to be homologous. phlA predicted PhlA, a protein of 264 amino acids that has no similarity to any proteins in the database but that shows partial conservation (mismatch=l) of a short chain alcohol dehydrogenase family signature, an ornithine/diaminopimelic acid/arginine decarboxylase family signature and a phosphopantetheine attachment site.

In PhlA this serine is replaced by threonine which has a similar reactive hydroxyl moiety. Symbols: | - represents identical residue; : - represents conservative replacement; . - represents semi-conservative replacements based on the similarity scores assigned in a PAM120 matrix. Short chain alcohol dehydrogenases catalyze the reversible oxidation of an alcohol to an aldehyde and are involved in many types of biosynthetic reactions. For example, in bacteria, acetoacetyl- CoA reductase (a member of the short-chain alcohol dehydrogenase family) in Zooglea ramigera and Alcaligenes eutrophus (Persson, et. al., Eur. J. Biochem. 200:537-543(1991)) is involved in the biosynthesis of poly-β-hydroxybutyrate. Ornithine, arginine and diaminopimelic acid decarboxylases are enzymes that act in the biosynthesis of polyamines and lysine, respectively. Phosphopantetheine is the prosthetic groups of acyl carrier proteins (ACP) in some multienzyme complexes where it serves as a "swinging arm" for the attachment of activated fatty and amino acid groups. phlB predicted protein PhlB, of 236 amino acids. PhlB did not show similarity to any known protein in the database nor did it show conservation of any common protein signatures. PhlB therefore may be a unique, as yet unidentified protein. phlC predicted PhlC, a protein of 389 amino acids with 27.9% identity and 49.7% similarity to the N-terminal portion of mammalian peroxisomal sterol carrier protein X (SCPx) ; the Z score for the two is 15; i.e., it is homologous to SCP-X. The 400 N- terminal amino acids of SCPx function as a 3-oxoacyl-CoA thiolase (Seedorf et. al., J. Biol . Chem. 269:21277-21283 (1993)); a hypothetical substrate binding site containing a cysteine residue and a glycine-rich C-terminal domain are conserved (Figure 5; Ossendorp et. al., Eur. J. Biochem. 201:233-39 (1991)). Putative substrate binding site: * Rat SCPx 78 SLGLTGIPIINVNNNCSTGST II • I • II • I PhlC 73 ALGISPAPTFMSTANCTSSSV * - marks the reactive cysteine residue.

The thiolase domain of SCPx efficiently catalyzes the thiolytic cleavage of a wide variety of 3-oxoacyl-CoA substrates, with preference for medium-length substrates; it is hypothesized to supply acetyl-CoA for anabolic reactions when cells are well- supplied with energy (Seedorf et. al., J. Biol . Chem. 269:21277- 21283 (1993)). Thus, PhlC may provide a source of starter units for the synthesis of Phi. Alternatively, thiolases share conserved residues in their condensing domains with β-ketoacyl synthases and chalcone synthases (M. Siggard-Andersen. Protein Seg. Data Anal . 3:325-335 (1993)), and the similarity we have detected between PhlC and SCPx may be consistent with activity analogous to chain elongation in fatty acid and polyketide synthesis. phlD predicted a protein, PhlD, of 349 amino acids with 27.9% identity and 48.0% similarity to members of the chalcone synthase/stilbene synthase (CHS/STS) family of enzymes from higher plants. Randomized binary comparisons of the amino acid sequences of PhlD and CHS from tomato gave a Z-score of 19.5. Thus, PhlD is homologous to chalcone synthases from plants. PhlD contained regions with extensive similarity to the active site and signature sequence domains of CHS/STS enzymes (Figure 6), but had surprisingly little similarity to prokaryotic /?-ketoacyl synthases, including those that catalyze similar condensing reactions (e.g., polyketide synthesis by actinomycetes) in bacteria. It is, to our knowledge, the first prokaryotic protein to show such extensive similarity to the CHS/STS protein family. These observations, and the apparent functional and biochemical parallels between plant defense by Phi-producing plant-associated microorganisms and plant self-defense mediated by phytoalexins (products of CHS/STS enzymes), provoke speculation as to possible gene exchange between plants and their bacterial colonists or more likely, a common evolutionary origin for these two mechanisms of defense. Chalcone synthases function as polyketide synthases to catalyze condensation reactions. For example, the CHS from Lycopersicon esculentum catalyzes the sequential addition of 3 acetyl units from malonyl-CoA to the phenylpropanoid ring of 4- coumaroyi-CoA and cyclization of the enzyme-bound intermediate to form naringenin chalcone, the central intermediate in the biosynthesis of many flavonoids. CHS accepts aliphatic-CoA esters as starter molecules, and acylphloroglucinols have been recovered as by-products of chalcone synthesis in vitro. This suggests that PhlD may be sufficient to catalyze the condensation and/or cyclization reactions required for MAPG synthesis (Figure 4). phlE predicted PhlE, a protein of 423 amino acids, that had 24.1% identity and 49.7% similarity to Staphylococcus aureus norA protein, a multidrug efflux transporter that contributes to fluoroquinone resistance. The Z score for the two proteins was 10.8. NorA and other such proteins are members of a very large superfamily of transmembrane solute facilitators that extends throughout prokaryotes, cyanobacteria, lower eukaryotes and higher plants and animals. Transporters specific for simple sugars, oligosaccharides, organic acids, organophosphate esters and drugs have been identified; among the most well-known representatives of the drug efflux subfamily are the tetracycline-H* antiporters driven by proton motive force. PhlE retained conserved structural features of these integral membrane permeases (Figure 7), including a central hydrophilic loop bordered on either side by six hydrophobic -helices. The region designated Red based on the results of Tn3HoHol mutagenesis (see Example 2) includes phlE. The homology between PhlE and known multidrug efflux proteins suggests that PhlE may function to export Phi from the cell, where it can react with media constituents or oxygen to produce the red pigment. That export occurs under native conditions is indicated by the fact that Phi is recovered in significant quantity from culture media (Table 3). Phloroglucinol (unacetylated) can condense with the coniferaldehyde moiety of lignin compounds from plants to give a reddish color; the reactive group here is the carbonyl of the aldehyde. Such reactive carbonyl groups may be present on compounds naturally present in media, or may be produced in media by growth of the Phi-producing bacteria. phlR predicted protein PhlR, of 418 amino acids. PhlR did not show similarity to any known proteins in the database but showed partial conservation (mismatch=l) of the thiolases 3 signature sequence. Thiolases signature 3 Consensus (A)(I)x(G)x C x G x G x(G) I I I I I I I I I I I PhlA K I F G G C E G K G V G * - marks the active site cysteine residue involved in deprotonation in the condensation reaction. Symbols: | - represents identical residue; : - represents conservative replacement; . - represents semi-conservative replacements based on the similarity scores assigned in a PAM120 matrix. Type II thiolases are involved in the thiolysis of acetoacetyl-CoA and in biosynthetic pathways such as poly-β- hydroxybutyrate synthesis and steroid biogenesis. phlF predicted PhlF, a protein of 202 amino acids with 23% identity and 47% similarity to tetracycline repressor protein. Conservation was concentrated within a helix-turn-helix (HTH) domain typical of known DNA-binding regulatory proteins such as λ cro and repressor proteins, phage 434 cro and repressor proteins, lac repressor, catabolite reactive protein (CRP), and E. coli tetracycline repressor protein. The HTH score obtained by using the Helix-Turn-Helix program in the EGCG package (Rice, P., Computer Group, European Molecular Biology Laboratory, PostFach 10-2209, 69012 Heidelberg, Germany) was higher for PhlF than were the scores for λ cro and repressor proteins and the phage 434 cro and repressor proteins. This score is a measure of the probability that the amino acid sequence predicts a functional DNA-binding domain, and strongly supports a role for PhlF in the regulation of gene expression. It is known that deletions of the TnIO and class E tetJ? tetracycline repressor genes resulting in truncation of the carboxy-terminal end of the encoded repressor proteins are derepressed in expression of the tetracycline resistance protein. The very high levels of Phi produced by transformed derivatives of P. fluorescens Q69c-80 containing a single chromosomal copy of a fragment including the truncated phlF gene and the phlACBDE and phlR genes (Table 3) argues that the phlF gene is a repressor of phi gene expression, and that truncation of PhlF permits derepressed synthesis of Phi in a manner analogous to that reported in the tetracycline resistance operon. The fact that pMON5120, containing the intact phlF gene, does not transfer Phi biosynthetic capability to the nonproducer strain M4-80R further strengthens this argument. Subcloning experiments are performed with the objective of determining whether the intact phlF gene is sufficient to repress expression of phi biosynthetic genes. The phlF gene is cloned in its entirety from pMON5120 on an EcoRV fragment, BamHI adapters are ligated to the ends, and the fragment is cloned into the BamHI site in pRK415, a broad host-range vector that can be maintained in Pseudomonas strains. This construction is introduced into Q2- 87: :Tn3HoHol-15 and Q2-87: :Tn3HoHol-40, reporter strains in which Tn3HoHol transposon insertions 15 (in phlD) 40 (in phlA ) have been introduced into the chromosome of Q2-87 by marker exchange (homologous recombination) . The BamHI fragment is sufficient to repress expression of phlA and phlD, as indicated by loss of blue colony color on media containing the chromogenic substrate X-gal, or by failure to detect β-galactosidase activity in a standard enzyme assay known to those skilled in the art. In contrast, introduction of pRK415 alone causes no change in colony color. Most of the proteins predicted by each of the phi genes showed similarities to proteins with known functions. However, since the pathway for synthesis of Phi in Pseudomonas is at present unknown, and because the identified sequence similarities are to proteins other than those known to catalyze polyketide biosynthetic reactions in bacteria (such as actinomycetes) , the actual role of the predicted proteins in Phi synthesis is yet to be determined. The cloned genes described herein permit fundamental studies on the mechanism of Phi biosynthesis in Pseudomonas spp. by providing information and materials for the generation of clones to express individual phi genes and to analyze the activities and roles of their products in the biosynthesis of Phi. Example 5. The native promoters for phlF and for phlA, phlB , phlC , phlO and phlR are contained within SEQ ID NO:4. The majority of the Tn3HoHol insertions in M4- 80R(pMON5122: :Tn3HoHol) derivative strains that were Lac + were oriented from right to left; only insertions 2, 3 and 38 were oriented from right to left (Figure 2). The lac promoter in the vector pRK415 is located distal to the left end of the cloned fragment as shown in Figure 2 and could direct expression of the lacZ gene only in M4-80R(pMON5122: :Tn3HoHol-38) . Expression of the lacZ genes in the remaining Tn3HoHol insertions therefore must be driven from promoters other than those in the vector. There were two sets of such insertions, one including those numbered 4, 5, 6, 8, 10, 14, 15, 16, 18, 19, 20, 21, 23, 24, 27, 28, 31, 32, 34, 37, and 39 in Figure 2, and the other including insertions 2 and 3. As these two sets of insertions are divergently oriented, the cloned fragment illustrated in Figure 2 must contain at least two divergently oriented transcriptional units and two promoters situated between phlA and phlF that are the native promoters of these genes. That this region carried promoter sequences was supported by the nature of its sequence. There were few or no open reading frames, and the sequence was very high in the bases A and T, which is characteristic of promoter sequences. Example 6. Cloning of the phlD gene and expression of its gene product. a. Cloning of phlD. The phlD gene is cloned as follows based on results of sequence analysis: the 5' end of phlD is cloned as a Accl-Sall fragment into pIC19H cut with C2al and Sa2l. The remaining 3' portion of the phlD is then introduced into the Sail site to regenerate the entire phlD gene in plasmid pPHLD. The cloned fragment from pPHLD is isolated as a i-iπdlll fragment and cloned into pTrcHis expression vectors A, B, and C (Invitrogen) to express the PhlD protein for assays of enzyme activity. The fragment is also cloned into the broad host range vector pRK415, and the resulting construction is introduced into Q2-87:Tn5-l by triparental mating to determine if it is sufficient to complement the mutation in the chromosomal phlD gene. The transconjugant so generated is tested for Phi biosynthesis by production of red pigment, bioassay, and extraction of Phi and MAPG. b. Expression of phlD and assay of enzymatic activity of expressed protein. For the preparation of active enzyme, the cells are grown, expression is induced, and the protein is isolated according to manufacturer's instructions. To assay enzyme activity, mix 15 μl of the isolated enzyme, 75 μl of buffer (0.2 M Hepes/KOH (Ph 7.0), ImM EDTA) , 5 μl of starter unit (e.g., 4-acetoacetyl-CoA or acetyl-CoA (lnmol)), and 5 μl of extender unit (e.g., [2-14C]malonyl-CoA (1.5nmol, 0.78GBq/mmol, Amersham Corp.). Incubate 30 min at 37°C; stop reaction by two sequential extractions with 0.15 ml of ethyl acetate. The solvent is removed by evaporation under vacuum (Speedvac), and the residue is dissolved in 10 μl ethyl acetate and analyzed by TLC in 15% acetic acid. Negative control samples spiked with Phi and/or MAPG are used to quantitate the efficiency of recovery (Lanz et al., J. Biol . Chem. 266:9971-9976 (1991)). Detection is by scintillation counting of samples scraped from the TLC plate. Cerulenin binds to the active site cysteine of condensing enzymes and is known to inhibit the activity of chalcone synthases. For cerulenin inhibition assays, cerulenin is dissolved in ethylene glycol monomethyl ether. Reactions mixes (as above) are pre-incubated with this solution for 10 min at 25°C before starting the reaction by adding substrates. Example 7. Intact phlD is necessary for Phi synthesis. The Tn5 insertion in Q2-87:Tn5-l is located with phlD; this mutation completely eliminates production of Phi as well as MAPG, suggesting that phlD is essential for the production of Phi. The BamHI-CIal fragment that encodes the 293 amino acids at the 3' end of the 349 amino acid PhlD protein was cloned into pIC19H, excised as J-indlll fragment, cloned in both orientations into the broad- host range vector pRK415 and introduced into Q2-87:Tn5-l and into strain M4-80R by triparental mating. In either orientation the cloned fragment was unable to complement the mutation in Q2-87:Tn5-l and did not direct Phi synthesis in M4-80R. Thus, intact PhlD is necessary for Phi synthesis. Example 8. Improvement of biocontrol capability of strains transformed with DNA sequences that confer of enhance Phi production. a. Preparation of Gaeumannomyces graminis var. tritici inoculated soil. Isolates of G. g. tritici were started from single ascospores from the roots of diseased wheat plants. The isolates were maintained on fifth-strength potato dextrose agar (PDA) (Duffy and Weller, Phytopathology 84:1407-1415 (1994)). To prepare G. g. tritici inoculum, an isolate was grown for 5-7 days on PDA in petri plates and then transferred as mycelium and accompanying agar medium to a 1-liter flask containing autoclaved oat kernels. Two hundred fifty cc of oat kernels per flask plus 125 ml of water were autoclaved at 121° C for 90 min on each of two consecutive days. The flasks were incubated at 25° C until the fungus colonized the oat kernels (about 3 wk) . The oats were shaken once during the incubation period. After colonization, the oat kernels were removed from the flasks, dried and stored. The inoculum was pulverized using a Waring blendor and sieved to obtain particles 0.25-0.5 mm in size. G. g. tritici inoculum was added to either steamed Ritzville silt loam or raw Puget silt loam (Pierson and Weller, Phytopathology 84:940-947 (1994)). b. Preparation of bacterial treated seeds. Wheat seeds were surface-sterilized by immersion in a 2.6% solution of sodium hypochlorite for 2 min followed by a 10 min rinse under a stream of water and a final rinse of sterile water. Seeds were dried in a stream of sterile air. Wild-type strains (Q2-87, Q65c-80, and Q69c-80), strains transformed with Phi biosynthetic genes carried on the plasmid pVSP41 [(Q2-87(pPHL5122) , Qc65(pPHl5122) , and Q69c- 80(pPHL5122) ] , strains bearing only the plasmid vector [Q65c- 80(pVSP41) and Q69c-80(pVSP41) ] and strain Q69c-80 transformed by Phi biosynthetic genes carried on a mini-transposon (Q69c- 80: :mTn5PHL12, Q69c-80: :mTn5PHL15 and Q69c-80: :mTn5PHL20) were cultured individually into 250-ml flasks containing 25 ml of nutrient broth yeast extract broth (Bacto-nutrient broth, 8 g; Bacto-yeast extract, 2 g; K 2 HP0 4 , 2 g KH 2 P0 4 , 0.5 g; MgS0 4 7H-0, 0.25 g; glucose, 5 g; H 2 0, 1000 ml) Vidaver, (Appl . Microbiol . 15:1523- 1524 (1967)) for 72 hr, centrifuged at 5,000 rpm for 10 min at 4°C, and suspended in 3 ml of 0.5% (w/w) of methylcellulose. Six grams of the surface-sterilized seeds were poured into the bacteria-methylcellulose mixture, shaken and then dried under a stream of sterile air. Seeds became coated with populations ranging from 4.0-9.0 log cfu/seed depending on the strain. A wide variety of microbiological media (both solid and liquid) can be substituted to culture the bacteria and a wide variety of compounds can be substituted to formulate the bacteria and to apply them to the seeds (PCT Application WO 94/01561). c. Growth chamber test using bacteria-treated seeds. Tests of bacterial strains and controls (nontreated seed or seed treated with methylcellulose) were conducted similar to tests reported by Ownley et al. {Phytopathology 82:178-184 (1992)). The test used plastic tubes (2.5-cm diameter x 16.5-cm long) held upright in plastic racks. The bottom of each tube was plugged with cotton and filled with a 6.5-cm-deep layer of sterile vermiculite overlaid with 10 g of soil amended with G. g. tritici oat kernel inoculum. Two wheat seeds treated with a bacterial strain or control seeds were sown per tube and covered with vermiculite. Each tube received 10 ml of water. The cones were incubated at 15-18° C for 3-4 weeks with a dark/light cycle of 12 hr and watered twice per week with 5 ml of dilute (1:3, v/v) Hoagland's solution (macroelements only) (Hoagland and Arnon, J. Cal . Agr. Exp. Stat . Circ. 347 (1950)). Each treatment was replicated five times, and each replicate consisted of a row of 10 separate tubes (20 individual plants). Treatments were arranged in racks in a randomized complete block design. After incubation, seedlings were removed from the soil, washed with water and evaluated on the basis of overall take-all severity and the number of root lesions using the following criteria. Overall take-all severity was measured on a scale of 0 (no disease) to 8 (plant nearly dead) as described by Ownley et al., {Phytopathology 82:178-184 (1992)). The severity of root disease (root disease index) was measured on the sections of the roots 3 cm or greater from the seed using a scale of 0-4, where 0 •= no take-all lesions, 1 - up to 25% of the roots infected, 2 = 26%-50% of the roots infected, 3 = 51%-75% of the roots infected and 4 = over 75% of roots infected. Disease rating was compared statistically among treatments by an analysis of variance (ANOVA) . Treatment means were compared by a least significant differences test (LSD) when significant differences among treatments was indicated by the ANOVA (Fisher's protected LSD) . Differences among treatments were determine based on a probability level of P=0.05. Table 5 shows the enhanced biocontrol of take-all achieved by insertion of the DNA sequences that code for Phi production. For example, strain Q2-87 (pPHL5122) had a significantly lower root disease index score than Q2-87. Strain Q65c-80(pPHL5122) had a significantly lower overall disease severity rating than Q65c-80 or Q65c-80(pVSP41) . Strain Q69c- 80(pPHL5122) had a significantly lower overall disease severity rating than the wild-type strain Q69c-80 or Q69c-80(PVSP41) . There was no soil x treatment interaction, therefore data from the raw Puget silt loam and pasteurized Ritzville silt loam were pooled. Table 5 Means in the same column followed by the same letter are not significantly different at P = 0.05 according to Fishers' protected least significant difference test (LSD) . Table 6 shows that DNA sequences that code for Phi production, when stably inserted into the genome of the recipient strain, conferred on the recipient strain the ability to suppress take-all at a substantially lower bacterial dose on the seed as compared to the wild-type strain. For example, strains Q69c-80: :mTn5PHLH2, Q69c-80: :mTn5PHLH5 and Q69c-80: :mTn5PHL20 applied at doses that were approximately 10,000-fold, 10,000-fold and 100-fold less, respectively than the dose of the wild-type strain Q69c-80 provided the same level of take-all suppression as Q69c-80. This is important because each 10-fold reduction in the dose of the bacterial treatment results in a substantial reduction in the cost of the biocontrol treatment to the farmer. There was no soil x treatment interaction, therefore data for the raw Puget silt loam and pasteurized Ritzville silt loam were pooled. Table 6 Means in the same column followed by the same letter are not significantly different at P = 0.05 according to Fishers' protected least significant difference test (LSD) . Example 9. Field testing of strains transformed with DNA sequences that confer of enhance Phi production. a. Preparation of bacterial treated seeds. Wild-type strains Q2-87, Q65c-80, and Q69c-80), strains transformed with Phi biosynthetic genes carried on the plasmid pVSP41 [ (Q2- 87(pPHL5122) , Qc65(pPHl5122) , and Q69c-80(pPHL5122) ], strains bearing only the plasmid vector [Q65c-80(pVSP41) and Q69c- 80(pVSP41)] and strain Q69c-80 transformed by Phi biosynthetic genes carried on a mini-transposon Q69c-80: :mTn5PHL15 and Q69c- 80: :mTn5PHL20) are propagated for 48-72 hr individually on agar plates of King's Medium B (Proteose peptone, 20 g; K 2 HP0 4 , 1.5 g; MgS0 4 7H-0, 1.5 g; glycerol, 10 g; aσar, 17 g; H 2 0, 1000 ml) (King et al., J. Lab. Clin . Med. 44:301-- J7 (1954)). The bacteria are scraped from the plates and suspended in 1.0% methylcellulose. Bacteria are mixed with seed at a rate of approximately one petri plate of bacteria and 4.0 ml of methylcellulose per 20 g of seed. Coated seeds are air dried and contain approximately 4.0-8.5 log cfu/seed depending on the strain. A wide variety of microbiological media (both solid and liquid) can be substituted to culture the bacteria and a wide variety of compounds can be substitute to formulate the bacteria and apply them to the seeds (see PCT Application WO 94/01561). Strains are tested in fields in which G. g. tritici is introduced as oat kernel inoculum. Treatments are arranged in a highly modified randomized complete block design as described by Pierson and Weller (supra). Seed treatments and control treatments each are sown in three 3.1-m rows. G. g. tritici , as whole oat kernel inoculum is introduced into the furrow immediately before the seed is sown by hand. Controls include methylcellulose-treated seed with G. g. tritici inoculum in the furrow, nontreated seed with G. g. tritici in the furrow, and nontreated seed without G. g. tritici . Strains also are tested in fields that are naturally infested with G. g. tritici . In such tests, controls consist only of nontreated seed and methylcellulose treated seed. The severity of take-all is assessed on the basis of plant height, the number of heads, the amount of root disease and the grain yield. Example 10. Use of strains transformed with DNA sequences that confer or enhance Phi production to suppress take-all in commercial wheat fields. Bacterial strains transformed with Phl-biosynthetic sequences are cultured as described in Examples 8 and 9 or by any commercial method of bacterial mass rearing and are applied to wheat seed directly or introduced into the seed furrow, for example as a spray at log 6-9 cfu/ml, at the time of planting in fields infested with G. g. var tritici in order to suppress take-all. Field preparation and seeding follows standard commercial practices and uses standard commercial equipment. The effectiveness of the bacterial treatment is determined as described in Example 9. Example 11. Use of strains transformed with DNA sequences that confer or enhance Phi production to suppress pathogens of wheat and barley in fields. Bacterial strains transformed with Phl-biosynthetic sequences, cultured as described in Examples 8 and 9, are applied to wheat or barley seed directly or introduced into the seed furrow at the time of planting in field infested with any wheat pathogen, for example, those belonging to the genera Gaeumannomyces, Pythium, Fusarium, Rhizoctonia, Tilletia, Urocystis, Cephalosporium, Mi crodochi rn , Typhul a. Example 12. Use of strains transformed with DNA sequences that confer or enhance Phi production to suppress pathogens that cause seed rot, damping-off, blights, root rots, wilts and crown rots of crops grown from seeds, cuttings or seedpieces. Bacterial strains transformed with Phl-biosynthetic sequences are cultured as described in Examples 8 and 9 and applied to seeds, cuttings, and seedpieces of crops infected with any pathogens, for example belonging to the genera Fusarium, Rhizoctonia, Pythium, Phytophthora , Verticillium, Septoria,, that cause seed rot, damping-off, blights, root rots, wilts and crown rots.
