     REFERENCE TO SEQUENCE LISTING SUBMITTED ELECTRONICALLY 
     The official copy of the sequence listing is submitted electronically via EFS-Web as an ASCII-formatted sequence listing with a file named “BCS199002WO_ST25.txt” created on Mar. 16, 2020, and having a size of 272 kilobytes, and is filed concurrently with the specification. The sequence listing contained in this ASCII-formatted document is part of the specification and is herein incorporated by reference in its entirety. 
     BACKGROUND OF THE INVENTION 
     Within the zone surrounding a plant&#39;s roots is a region called the rhizosphere. In the rhizosphere, bacteria, fungi, and other organisms compete for nutrients and for binding to the root structures of the plant. Both detrimental and beneficial bacteria and fungi can occupy the rhizosphere. The bacteria, fungi, and the root system of the plant can all be influenced by the actions of peptides, enzymes, and other proteins in the rhizosphere. Augmentation of soil or treatment of plants with certain of these peptides, enzymes, or other proteins would have beneficial effects on the overall populations of beneficial soil bacteria and fungi, create a healthier overall soil environment for plant growth, improve plant growth, and provide for the protection of plants against certain bacterial and fungal pathogens. However, previous attempts to introduce peptides, enzymes, and other proteins into soil to induce such beneficial effects on plants have been hampered by the low survival of enzymes, proteins, and peptides in soil. Additionally, the prevalence of proteases naturally present in the soil can lead to degradation of the proteins in the soil. The environment around the roots of a plant (the rhizosphere) is a unique mixture of bacteria, fungi, nutrients, and roots that has different qualities than that of native soil. The symbiotic relationship between these organisms is unique, and could be altered for the better with inclusion of exogenous proteins. The high concentration of fungi and bacteria in the rhizosphere causes even greater degradation of proteins due to abnormally high levels of proteases and other elements detrimental to proteins in the soil. In addition, enzymes and other proteins introduced into soil can dissipate away from plant roots quickly. 
     Thus, there exists a need in the art for a method for effectively delivering peptides, enzymes, and other proteins to plants (e.g., to plant root systems) and for extending the period of time during which such molecules remain active. Furthermore, there exists a need in the art for a method of selectively targeting such peptides, enzymes, and proteins to the rhizosphere and to plant leaves and plant roots in particular.

     Definitions 
     When the articles “a”, “an”, “one”, “the”, and “said” are used herein, they mean “at least one” or “one or more” unless otherwise indicated. 
     The term “ Bacillus cereus  family member” as used herein refers to any  Bacillus  species that is capable of producing an exosporium. Thus, the  Bacillus cereus  family of bacteria includes the species  Bacillus anthracis, Bacillus cereus, Bacillus thuringiensis, Bacillus mycoides, Bacillus pseudomycoides, Bacillus samanii, Bacillus gaemokensis, Bacillus weihenstephensis , and  Bacillus toyoiensis. Bacillus cereus  family members are also referred to in the art as “ Bacillus cereus  senso lato.” 
     The terms “comprising,” “including” and “having” are intended to be inclusive and mean that there may be additional elements other than the listed elements. 
     The term “free enzyme” as used herein refers to an enzyme preparation that is substantially free of intact cells. The term “free enzyme” includes, but is not limited to, crude cell extracts containing an enzyme, partially purified, substantially purified, or purified enzyme. Free enzymes can optionally be immobilized on a chemical matrix or support to allow for controlled release of the enzyme. The term “immobilizing” as used herein in reference to immobilizing an enzyme on a matrix or support refers to the binding of the enzyme to the matrix or support such that the enzyme is maintained on the matrix or support or released from the support over a controlled period of time, instead of dissipating into the environment in an uncontrolled manner. Illustrative matrices and supports include, but are not limited to, charcoal, biochar, nanocarbon, agarose, an alginate, cellulose, a cellulose derivative, silica, plastic, stainless steel, glass, polystyrene, a ceramic, dolomite, a clay, diatomaceous earth, talc, a polymer, a gum, a water-dispersable material, and combinations of any thereof. 
     The term “foliar” used herein with respect to the application of enzymes or recombinant microorganisms to plants means that the enzyme or recombinant microorganism is applied to one or more aerial portions of the plant, including stems, leaves, fruits, flowers, or other exposed aerial portions of the plant. 
     The term “fusion protein” as used herein refers to a protein having a polypeptide sequence that comprises sequences derived from two or more separate proteins. A fusion protein can be generated by joining together a nucleic acid molecule that encodes all or part of a first polypeptide with a nucleic acid molecule that encodes all or part of a second polypeptide to create a nucleic acid sequence which, when expressed, yields a single polypeptide having functional properties derived from each of the original proteins. 
     The term “germination rate” as used herein refers to the number of seeds that germinate during a particular time period. For example, a germination rate of 85% indicates that 85 out of 100 seeds germinate during a given time period. 
     The term “inactivate” or “inactivation” as used herein in reference to the inactivation of spores of a recombinant  Bacillus cereus  family member means that the spores are unable to germinate, or that the spores can germinate, but are damaged such that germination does not result in a living bacterium. The terms “partially inactivate” or “partial inactivation” mean that a percentage of the spores are inactivated, but that some spores retain the ability to germinate and return to a live, replicating state. The term “genetic inactivation” refers to inactivation of spores a recombinant  Bacillus cereus  family member by a mutation of the spore&#39;s DNA that results in complete or partial inactivation of the spore. The terms “physical inactivation” and “chemical inactivation” refer to inactivation of spores using any physical or chemical means, e.g., by heat treatment, gamma irradiation, x-ray irradiation, UV-A irradiation, UV-B irradiation, or treatment with a solvent such as glutaraldehyde, formaldehyde, hydrogen peroxide, acetic acid, bleach, chloroform, phenol, or any combination thereof. 
     The terms “native sequence”, “native amino acid sequence”, “wild-type sequence”, and “wild-type amino acid sequence” are used interchangeably herein to refer to an amino acid sequence as it exists in a naturally occurring protein. 
     A “plant growth medium” includes any material that is capable of supporting the growth of a plant. 
     The terms “promoting plant growth” and “stimulating plant growth” are used interchangeably herein, and refer to the ability to enhance or increase at least one of the plant&#39;s height, weight, leaf size, root size, fruit size, shoot size or stem size, and/or the ability to increase protein yield from the plant, and/or to increase crop yield, and/or to improve plant vigor. For example, this may relate to increased length and/or fresh and/or dry weights of roots and/or shoots of treated plants or crops compared to untreated plants or crops. 
     Increased yield of a plant, in particular of an agricultural, silvicultural and/or ornamental plant, means that the yield of a product of the respective plant is increased by a measurable amount over the yield of the same product of the plant produced under the same conditions, but without the application of the compositions disclosed herein. 
     Improved plant vigor includes the following: (a) improved vitality of the plant, (b) improved quality of the plant and/or of the plant products, e.g., enhanced protein content, (c) improved visual appearance, (d) delay of senescence, (e) enhanced root growth and/or more developed root system (e.g., determined by the dry mass of the root), (f) enhanced nodulation, in particular rhizobial nodulation, (g) longer panicles, (h) bigger leaf blade, (i) less dead basal leaves, (j) increased chlorophyll content, (k) prolonged photosynthetically active period, (l) increased or improved plant stand density, (m) less plant verse (lodging), (n) increased plant weight, (o) increased plant height, (p) tillering increase, (q) stronger and/or more productive tillers, (r) less non-productive tillers, (s) enhanced photosynthetic activity and/or enhanced pigment content and thus greener leaf color, (t) earlier and/or improved germination, (u) improved and/or more uniform and/or earlier emergence, (v) increased shoot growth, (w) earlier flowering, (x) earlier fruiting, (y) earlier grain maturity, (z) less fertilizers needed, (aa) less seeds needed. 
     The term “recombinant” as used in reference to the bacteria described herein encompasses bacteria having any genetic modification as compared to wild-type bacteria of the same type, including bacteria that have been modified to delete of a gene or a portion of a gene (e.g., bacteria that have a “knock-out” of a gene), as well as bacteria that have been modified to express an exogenous peptide or protein. 
     The term “rhizosphere” is used interchangeably with “root zone” to denote that segment of the soil that surrounds the roots of a plant and is influenced by them. 
     The term “synergistically effective amount” as used herein refers an amount of a first substance (e.g., a first enzyme) that when used in combination with a second substance (e.g., a second enzyme) produces a biological effect that is greater than the sum of the biological effects of each of the respective first and second substances when used alone. 
     The term “targeting sequence” as used herein refers to a polypeptide sequence that, when present as part of a longer polypeptide or a protein, results in the localization of the longer polypeptide or the protein to a specific subcellular location. The targeting sequences described herein result in localization of proteins to the exosporium of a  Bacillus cereus  family member.

     DETAILED DESCRIPTION OF THE INVENTION 
     I. Fusion Proteins for Expression in  Bacillus Cereus  Family Members 
     The present invention relates to fusion proteins comprising a targeting sequence, exosporium protein, or exosporium protein fragment that targets the fusion protein to the exosporium of a recombinant  Bacillus cereus  family member. The fusion proteins further comprise an enzyme having serine protease activity. When expressed in  Bacillus cereus  family member bacteria, these fusion proteins are targeted to the exosporium layer of the spore and are physically oriented such that the serine protease is displayed on the outside of the spore. 
     This  Bacillus  exosporium display (BEMD) system can be used to deliver the serine protease to plants (e.g., to plant foliage, fruits, flowers, stems, or roots) or to a plant growth medium such as soil. Enzymes and proteins delivered to the soil or another plant growth medium in this manner persist and exhibit activity in the soil for extended periods of time. Introduction of recombinant  Bacillus cereus  family member bacteria expressing the fusion proteins described herein into soil or the rhizosphere of a plant leads to a beneficial enhancement of plant growth and/or to control pests, such as nematodes, in many different soil conditions. The use of the BEMD to create these enzymes allows them to continue to exert their beneficial results to the plant and the rhizosphere over the first months of a plant&#39;s life. 
     In addition, as is described further hereinbelow, the BEMD system can be modified such that the exosporium of the recombinant  Bacillus cereus  family member can be removed from the spore, generating exosporium fragments containing the fusion proteins. The exosporium fragments can also be used to deliver the serine proteases to plants in a cell-free preparation. 
     A. Targeting Sequences, Exosporium Proteins, and Exosporium Protein Fragments for Targeting Enzymes Having Serine Protease Activity to the Exosporium of a  Bacillus cereus  Family Member 
     For ease of reference, descriptions of the amino acid sequences for the targeting sequences, exosporium proteins, and exosporium protein fragments that can be used for targeting of enzymes or proteins (e.g., enzymes having serine protease activity) to the exosporium of a  Bacillus cereus  family members, are provided in Table 1 together with their SEQ ID NOs.

       Bacillus  is a genus of rod-shaped bacteria. The  Bacillus cereus  family of bacteria includes any  Bacillus  species that is capable of producing an exosporium. Thus, the  Bacillus cereus  family of bacteria includes the species  Bacillus anthracis, Bacillus cereus, Bacillus thuringiensis, Bacillus mycoides, Bacillus pseudomycoides, Bacillus samanii, Bacillus gaemokensis, Bacillus weihenstephensis , and  Bacillus toyoiensis . Under stressful environmental conditions,  Bacillus cereus  family bacteria undergo sporulation and form oval endospores that can stay dormant for extended periods of time. The outermost layer of the endospores is known as the exosporium and comprises a basal layer surrounded by an external nap of hair-like projections. Filaments on the hair-like nap are predominantly formed by the collagen-like glycoprotein BclA, while the basal layer is comprised of a number of different proteins. Another collagen-related protein, BclB, is also present in the exosporium and exposed on endospores of  Bacillus cereus  family members. BclA, the major constituent of the surface nap, has been shown to be attached to the exosporium with its amino-terminus (N-terminus) positioned at the basal layer and its carboxy-terminus (C-terminus) extending outward from the spore. 
     The scientific literature describes the  Bacillus cereus  “family” or “group” as a subgroup within the genus  Bacillus . See Priest et al., “Population Structure and Evolution of the  Bacillus cereus  Group,” J. Bacteriology, 2004, vol. 186. no. 23, pp. 7959-7970; Peng et al., “The Regulation of Exosporium-Related Genes in  Bacillus thuringiensis ,” Nature Scientific Reports, 2016, vol. 6, no. 19005, pp. 1-12. Peng et al. states:
         Spores of the  B. cereus  group are complex, multilayered structures. The nucleoid containing core is enclosed within a peptidoglycan cortex, which is surrounded by the spore coat. Spores of all the  B. cereus  group species are encircled by an additional loose-fitting layer called the exosporium, which is not present on other species such as  Bacillus subtilis , for which the coat constitutes the outermost layer of the mature spore. The exosporium is a balloon-like layer that acts as the outer permeability barrier of the spore and contributes to spore survival and virulence.       

     It was previously discovered that certain sequences from the N-terminal regions of BclA and BclB could be used to target a peptide or protein to the exosporium of a  Bacillus cereus  family member endospore (see U.S. Patent Application Publication Nos. 2010/0233124 and 2011/0281316, and Thompson et al., “Targeting of the BclA and BclB Proteins to the  Bacillus anthracis  Spore Surface”, Molecular Microbiology 70(2):421-34 (2008)). It was also found that the BetA/BAS3290 protein of  Bacillus anthracis  localized to the exosporium. Further targeting sequences, as well as exosporium proteins and fragments of exosporium proteins, that can be incorporated into a fusion protein and used to target a peptide or protein of interest to the exosporium of a recombinant  Bacillus cereus  family member are described in U.S. Patent Application Publication Nos. 2016/0031948 and 2016/0108096, which are incorporated by reference herein in their entirety. 
     In particular, amino acids 20-35 of BclA from  Bacillus anthracis  Sterne strain have been found to be sufficient for targeting to the exosporium. A sequence alignment of amino acids 1-41 of BclA (SEQ ID NO: 1) with the corresponding N-terminal regions of several other  Bacillus cereus  family exosporium proteins and  Bacillus cereus  family proteins having related sequences is shown in  FIGS. 1A and 1B . As can be seen from  FIGS. 1A and 1B , there is a region of high homology among all of the proteins in the region corresponding to amino acids 20-41 of BclA. However, in these sequences, the amino acids corresponding to amino acids 36-41 of BclA contain secondary structure and are not necessary for fusion protein localization to the exosporium. The conserved targeting sequence region of BclA (amino acids 20-35 of SEQ ID NO: 1) is shown in bold in  FIGS. 1A and 1B . A more highly conserved region spanning amino acids 25-35 of BclA within the targeting sequence is underlined in the sequences in  FIGS. 1A and 1B , and is the recognition sequence for ExsFA/BxpB/ExsFB and homologs, which direct and assemble the described proteins on the surface of the exosporium. The amino acid sequences of SEQ ID NOs. 3, 5, and 7 in  FIG. 1A  are amino acids 1-33 of  Bacillus anthracis  Sterne strain BetA/BAS3290, a methionine followed by amino acids 2-43 of  Bacillus anthracis  Sterne strain BAS4623, and amino acids 1-34 of  Bacillus anthracis  Sterne strain BclB, respectively. (For BAS4623, it was found that replacing the valine present at position 1 in the native protein with a methionine resulted in better expression.) As can be seen from  FIG. 1A , each of these sequences contains a conserved region corresponding to amino acids 20-35 of BclA (SEQ ID NO: 1; shown in bold), and a more highly conserved region corresponding to amino acids 25-35 of BclA (underlined). 
     Additional proteins from  Bacillus cereus  family members also contain the conserved targeting region.

Al Hakam hypothetical protein BALH_2230, SEQ ID NO: 67 is amino acids 1-33 of  B. cereus  ATCC 14579 triple helix repeat-containing collagen, SEQ ID NO: 69 is amino acids 1-44 of  B. cereus  collagen triple helix repeat, SEQ ID NO: 71 is amino acids 1-38 of  B. cereus  ATCC 14579 triple helix repeat-containing collagen, SEQ ID NO: 73 is amino acids 1-30 of  B. cereus  E33L hypothetical protein BCZK1835, SEQ ID NO: 75 is amino acids 1-48 of  B. weihenstephanensis  KBAB4 triple helix repeat-containing collagen, SEQ ID NO: 77 is amino acids 1-30 of  B. cereus  ATCC 14579 triple helix repeat-containing collagen, SEQ ID NO: 79 is amino acids 1-39 of  B. cereus  ATCC 14579 hypothetical protein BC4725, SEQ ID NO: 81 is amino acids 1-44 of  B. cereus  E33L hypothetical protein BCZK4476, SEQ ID NO: 83 is amino acids 1-40 of  B. anthracis  str. ‘Ames Ancestor’ triple helix repeat-containing collagen, SEQ ID NO: 85 is amino acids 1-34 of  B. thuringiensis  serovar konkukian str. 97-27 BclA protein, SEQ ID NO: 87 is amino acids 1-34 of  B. cereus  ATCC 10987 conserved hypothetical protein, SEQ ID NO: 89 is amino acids 1-34 of  B. cereus  ATCC 14579 triple helix repeat-containing collagen, SEQ ID NO: 91 is amino acids 1-99 of  B. cereus  exosporium leader peptide partial sequence, and SEQ ID NO: 93 is amino acids 1-136 of  B. weihenstephanensis  hypothetical protein ER45_27600. As shown in  FIGS. 1A and 1B , each of the N-terminal regions of these proteins contains a region that is conserved with amino acids 20-35 of BclA (SEQ ID NO: 1), and a more highly conserved region corresponding to amino acids 25-35 of BclA. 
     Amino acids 1-41 of BclA from  B. thuringiensis  (SEQ ID NO: 204) and amino acids 1-41 of BclA from  B. anthracis  (SEQ ID NO: 206) are identical to SEQ ID NO: 2 and are thus not depicted in  FIG. 1 . 
     Any portion of BclA which includes amino acids 20-35 can be used as to target a fusion protein to the exosporium. In addition, full-length exosporium proteins or exosporium protein fragments can be used for targeting the fusion proteins to the exosporium. Thus, full-length BclA or a fragment of BclA that includes amino acids 20-35 can be used for targeting to the exosporium. For example, full length BclA (SEQ ID NO: 2, 204, or 206) or a midsized fragment of BclA that lacks the carboxy-terminus such as SEQ ID NO: 95 or 207 (amino acids 1-196 of BclA) or 205 (amino acids 1-166 of BclA) can be used to target the fusion proteins to the exosporium. Midsized fragments such as the fragments of SEQ ID NO: 95, 205, and 207 have less secondary structure than full length BclA and have been found to be suitable for use as a targeting sequence. The targeting sequence can also comprise much shorter portions of BclA which include amino acids 20-35, such as SEQ ID NO: 1 (amino acids 1-41 of BclA), amino acids 1-35 of SEQ ID NO: 1, amino acids 20-35 of SEQ ID NO: 1, or SEQ ID NO: 96 (a methionine residue linked to amino acids 20-35 of BclA). Even shorter fragments of BclA which include only some of amino acids 20-35 also exhibit the ability to target fusion proteins to the exosporium. For example, the targeting sequence can comprise amino acids 22-31 of SEQ ID NO: 1, amino acids 22-33 of SEQ ID NO: 1, or amino acids 20-31 of SEQ ID NO: 1.

     Furthermore, it has been found that sequences shorter than amino acids 20-35 of BclA can be used to target a fusion protein to the exosporium of a recombinant  Bacillus cereus  family member. In particular, amino acids 20-33 of BclA, amino acids 20-31 of BclA, amino acids 21-33 of BclA, or amino acids 23-31 of BclA can be used to target a fusion protein to the exosporium of a recombinant  Bacillus cereus  family member. Thus, the targeting sequence can consist of amino acids 20-33 of SEQ ID NO: 1, amino acids 20-31 of SEQ ID NO: 1, amino acids 21-33 of SEQ ID NO: 1, or amino acids 23-31 of SEQ ID NO: 1. The corresponding regions of any of the SEQ ID NOs. shown in  FIGS. 1A and 1B  can also be used to target a fusion protein to the exosporium of a recombinant  Bacillus cereus  family member. By “corresponding regions,” it is meant that when the sequences are aligned with SEQ ID NO: 1, as shown in  FIGS. 1A and 1B , the regions of the other amino acid sequences that align with the amino acids of SEQ ID NO: are the “corresponding regions” of those sequences. Thus, for example, amino acids 12-25 of SEQ ID NO: 3, amino acids 23-36 of SEQ ID NO: 5, amino acids 13-26 of SEQ ID NO: 7, etc., can be used to target a fusion protein to the exosporium of a recombinant  Bacillus cereus  family member, since these regions align with amino acids 20-33 of SEQ ID NO: 1 as shown in  FIG. 1A . 
     Even shorter regions within amino acids 20-35 of BclA can also be used for targeting a fusion protein to the exosporium of a recombinant  Bacillus cereus  family member. In particular, any amino acid sequence that includes amino acids 25-30 of SEQ ID NO: 1 or the corresponding amino acids from any of the sequences shown in  FIGS. 1A and 1B  can be used. A skilled person will recognize that starting with amino acids 25-30 of SEQ ID NO: 1 or the corresponding region of any of the sequences shown in  FIGS. 1A and 1B , additional amino acids can be added to the amino-terminus, the carboxy terminus, or both the amino- and carboxy termini to create a targeting sequence that will be effective for targeting a fusion protein to the exosporium of a recombinant  Bacillus cereus  family member. 
     In addition, it can readily be seen from the sequence alignment in  FIGS. 1A  and 1B of the &#39;661 Publication that while amino acids 20-35 of BclA are conserved, and amino acids 25-35 are more conserved, some degree of variation can occur in this region without affecting the ability of the targeting sequence to target a protein to the exosporium.  FIGS. 1A and 1B  of the &#39;661 Publication list the percent identity of each of the corresponding amino acids of each sequence to amino acids 20-35 of BclA (“20-35% Identity”) and to amino acids 25-35 of BclA (“25-35% Identity”). Thus, for example, as compared to amino acids 20-35 of BclA, the corresponding amino acids of BetA/BAS3290 are about 81.3% identical, the corresponding amino acids of BAS4623 are about 50.0% identical, the corresponding amino acids of BclB are about 43.8% identical, the corresponding amino acids of BAS1882 are about 62.5% identical, the corresponding amino acids of the KBAB4 2280 gene product are about 81.3% identical, and the corresponding amino acids of the KBAB4 3572 gene product are about 81.3% identical. The sequence identities over this region for the remaining sequences are listed in  FIGS. 1A and 1B . 
     With respect to amino acids 25-35 of BclA, the corresponding amino acids of BetA/BAS3290 are about 90.9% identical, the corresponding amino acids of BAS4623 are about 72.7% identical, the corresponding amino acids of BclB are about 54.5% identical, the corresponding amino acids of BAS1882 are about 72.7% identical, the corresponding amino acids of the KBAB4 2280 gene product are about 90.9% identical, and the corresponding amino acids of the KBAB4 3572 gene product are about 81.8% identical. The sequence identities over this region for the remaining sequences are listed in  FIGS. 1A and 1B . 
     Thus, the targeting sequence can comprise an amino acid sequence having at least about 43% identity with amino acids 20-35 of SEQ ID NO: 1, wherein the identity with amino acids 25-35 is at least about 54%. Alternatively, the targeting sequence consists of an amino acid sequence consisting of 16 amino acids and having at least about 43% identity with amino acids 20-35 of SEQ ID NO: 1, wherein the identity with amino acids 25-35 is at least about 54%.

     The skilled person will recognize that variants of the above sequences can also be used as targeting sequences, so long as the targeting sequence comprises amino acids 20-35 of BclA, the corresponding amino acids of BetA/BAS3290, BAS4263, BclB, BAS1882, the KBAB4 2280 gene product, or the KBAB 3572 gene product, or a sequence comprising any of the above noted sequence identities to amino acids 20-35 and 25-35 of BclA is present. 
     Certain  Bacillus cereus  family exosporium proteins which lack regions having homology to amino acids 25-35 of BclA can also be used to target a peptide or protein to the exosporium of a  Bacillus cereus  family member. In particular, the fusion proteins can comprise an exosporium protein comprising SEQ ID NO: 108 ( B. mycoides  InhA), an exosporium protein comprising SEQ ID NO: 109 ( B. anthracis  Sterne BAS1141 (ExsY)), an exosporium protein comprising SEQ ID NO: 110 ( B. anthracis  Sterne BAS1144 (BxpB/ExsFA)), an exosporium protein comprising SEQ ID NO: 111 ( B. anthracis  Sterne BAS1145 (CotY)), an exosporium protein comprising SEQ ID NO: 112 ( B. anthracis  Sterne BAS1140), an exosporium protein comprising SEQ ID NO: 113 ( B. anthracis  H9401 ExsFB), an exosporium protein comprising SEQ ID NO: 114 ( B. thuringiensis  HD74 InhA1), an exosporium protein comprising SEQ ID NO: 115 ( B. cereus  ATCC 10876 ExsJ), an exosporium protein comprising SEQ ID NO: 116 ( B. cereus  ExsH), an exosporium protein comprising SEQ ID NO: 117 ( B. anthracis  Ames YjcA), an exosporium protein comprising SEQ ID NO: 118 ( B. anthracis  YjcB), an exosporium protein comprising SEQ ID NO: 119 ( B. anthracis  Sterne BclC), an exosporium protein comprising SEQ ID NO: 120 ( Bacillus thuringiensis  serovar konkukian str. 97-27 acid phosphatase), an exosporium protein comprising SEQ ID NO: 121 ( B. thuringiensis  HD74 InhA2), an exosporium protein comprising SEQ ID NO: 122 ( B. mycoides  InhA3), or an exosporium protein comprising SEQ ID NO: 203 ( B. anthracis  CotY variant). Inclusion of an exosporium protein comprising any of SEQ ID NOs: 108-122 or 203 in the fusion proteins described herein will result in targeting to the exosporium of a  B. cereus  family member. 
     Moreover, exosporium proteins having a high degree of sequence identity with any of the full-length exosporium proteins or the exosporium protein fragments described above can also be used to target a peptide or protein to the exosporium of a  Bacillus cereus  family member.

     The fusion protein can comprise an exosporium protein having at least 98% identity with any one of SEQ ID NOs: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94, 95, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 122, and 203. 
     The fusion protein can comprise an exosporium protein having at least 99% identity with any one of SEQ ID NOs: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94, 95, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 122, and 203. 
     The fusion protein can comprise an exosporium protein having 100% identity with any one of SEQ ID NOs: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94, 95, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 122, and 203. 
     The targeting sequence, exosporium protein or exosporium protein fragment of the present invention may also be described in terms of a motif that provides the targeting function.  FIGS. 1A and 1B  show a sequence alignment of the amino-terminal region of BclA (SEQ ID NO: 1) with the corresponding amino-terminal regions of a number of other  Bacillus cereus  family member exosporium proteins. As can be seen from  FIG. 1 , there is a conserved motif at amino acids 20-35 of BclA (shown in bold in  FIG. 1 ), with a more highly conserved motif at amino acids 25-35 of BclA (shown in bold and underlined in  FIG. 1 ). This more highly conserved region is the recognition sequence for ExsFA/BxpB/ExsFB and homologs, which direct and assemble the described exosporium proteins on the surface of the exosporium. 
     Furthermore, while amino acids 20-35 of BclA are conserved, and amino acids 25-35 are more conserved, some degree of variation can occur in this region without affecting the ability of the targeting sequence to target a protein to the exosporium.  FIG. 1  lists the percent identity of the corresponding amino acids of each sequence to amino acids 20-35 of BclA (“20-35% Identity”) and to amino acids 25-35 of BclA (“25-35% Identity”). Sequences having a targeting sequence identity as low as 43.8% with amino acids 20-35 of BclA (SEQ ID NO: 1), wherein the identity with amino acids 25-35 of BclA is 54.5%, retain the ability to target fusion proteins to the exosporium.

Table 58 shows the enzyme levels of phosphatidylcholine-specific phospholipase C gene (PC-PLC) and lipase on  Bacillus cereus  family member spores expressing fusion proteins containing these enzymes and various targeting sequences.

     These data show that targeting of a protein of interest (e.g., an enzyme) to the exosporium proteins can be achieved using targeting sequences having 50-68.8% identity to amino acids 20-35 of BclA (SEQ ID NO: 1), wherein the identity to amino acids 25-35 of BclA is 63.6% to 81.8%. Such motif is present in a targeting sequence, exosporium protein, or exosporium protein fragment that targets the fusion protein to the exosporium of the recombinant  Bacillus  bacterium and comprises the sequence X 1 -X 2 -X 3 -X 4 -X 5 -X 6 -X 7 -X 8 -X 9 -X 10 -X 11 -X 12 -X 13 -X 14 -X 15 -X 16 , wherein: 
     X 1  is any amino acid or absent; 
     X 2  is phenylalanine (F), leucine (L), isoleucine (I), or methionine (M); 
     X 3  is any amino acid; 
     X 4  is proline (P) or serine (S); 
     X 5  is any amino acid; 
     X 6  is leucine (L), asparagine (N), serine (S), or isoleucine (I); 
     X 7  is valine (V) or isoleucine (I); 
     X 8  is glycine (G); 
     X 9  is proline (P); 
     X 10  is threonine (T) or proline (P); 
     X 11  is leucine (L) or phenylalanine (F); 
     X 12  is proline (P); 
     X 13  is any amino acid; 
     X 14  is any amino acid; 
     X 15  is proline (P), glutamine (Q), or threonine (T); and 
     X 16  is proline (P), threonine (T), or serine (S). 
     Any of the targeting sequences, exosporuim proteins, or exosporium protein fragments can be used to target any protein or peptide of interest, including the proteins having serine protease activity described herein, to the exosporium of a recombinant  Bacillus cereus  family member. 
     For example, any of the targeting sequences, exosporium proteins, or exosporium protein fragments (e.g., any of SEQ ID NOs: 203-207) can be used to target a protein or peptide of interest (e.g., an enzyme having the serine protease activity of SEQ ID NO: 210, 211, or 212) to the exosporium of a recombinant  Bacillus cereus  family member. 
     During sporulation of a recombinant  Bacillus cereus  family member expressing any of the fusion proteins described herein, the targeting motif, exosporium protein, or exosporium protein fragment is recognized by the spore exosporium assembly machinery and directed to the exosporium, resulting in display of the protein or peptide of interest portion of the fusion protein (e.g., the enzyme having serine protease activity) on the outside of the spore. 
     The use of different targeting sequences allows for control of the expression level of the fusion protein on the surface of the  Bacillus cereus  family member spore. Use of certain of the targeting sequences described herein will result in a higher level of expression of the fusion protein, whereas use of others of the targeting sequences will result in lower levels of expression of the fusion protein on the surface of the spore. 
     In any of the fusion proteins described herein, the targeting sequence, exosporium protein, or exosporium protein fragment can comprise the amino acid sequence GXT at its carboxy terminus, wherein X is any amino acid. 
     In any of the fusion proteins described herein, the targeting sequence, exosporium protein, or exosporium protein fragment, can comprise an alanine residue at the position of the targeting sequence that corresponds to amino acid 20 of SEQ ID NO: 1. 
     In any of the fusion proteins described herein, the targeting sequence, exosporium protein, or exosporium protein fragment can further comprise a methionine, serine, or threonine residue at the amino acid position immediately preceding the first amino acid of the targeting sequence, exosporium protein, or exosporium protein fragment or at the position of the targeting sequence that corresponds to amino acid 20 of SEQ ID NO: 1. 
     B. Serine Protease Proteins 
     The fusion proteins can comprise an enzyme having serine protease activity. 
     Serine proteases are one of the largest and mostly widely distributed class of proteases. Serine proteases cleave peptide bonds at serine residues within a specific recognition site in a protein. These proteases are frequently used by bacteria for nutrient scavenging in the environment. Serine proteases have also been show to exhibit nematicidal activity through digestion of intestinal tissue in nematodes. Studies of  Bacillus firmus  strain DS-1, which shows nematicidal activity against  Meloidogyne incognita  and soybean cyst nematode, revealed that the serine protease produced by that strain has serine protease activity and degraded the intestinal tissues of nematodes. Geng, C., et al., “A Novel Serine Protease, Sep1, from  Bacillus firmus  DS-1 Has Nematicidal Activity and Degrades Multiple Intestinal-Associated Nematode Proteins”, Scientific Reports, 2016, vol. 6, no. 25012. 
     Other studies have shown that serine proteases have activity against pathogens such as fungal plant pathogens and oomycetes, such as  Pythium . See Dunne et al., “Overproduction of an Inducible Extracellular Serine Protease Improves Biological Control of  Pythium ultimum  by  Stenotrophomonas maltophilia  strain W81,” Microbiology, 2000, vol. 146, pp. 2069-2078, and Yen, Y., et al., “An Antifungal Protease Produced by  Pseudomonas aeruginosa  M-1001 with Shrimp and Crab Shell Powder as a Carbon Source,” Enzyme and Microbial Technology, 2006, vol. 39, pp. 311-317. 
     In Table 2, SEQ ID NOs: 210-212 are amino acid sequences for wild-type enzymes and a variant enzyme that exhibit or are predicted to exhibit serine protease activity. Thus, for example, SEQ ID NOs: 210 and 211 provide the amino acid sequence for wild-type serine protease enzymes from two different  Bacillus firmus  strains and have 98% sequence similarity. SEQ ID NO: 212 provides the amino acid sequence for the same enzyme as in SEQ ID NO: 210, except for a deletion of amino acids 181-240 of SEQ ID NO: 210, such that SEQ ID NOs: 210 and 212 have 81% sequence similarity. The catalytic residues referenced in Geng, et al., 2016, above, are maintained in the variant serine protease amino acid sequence of SEQ ID NO: 212.

     Signal Peptides 
     When a fusion protein comprises an enzyme whose native sequence includes a signal peptide, the enzyme can be used without the signal peptide. Alternatively, the native signal peptide (or another signal peptide) can optionally be included at the amino terminus of the enzyme, immediately preceding the first amino acid of the enzyme sequence. 
     In addition, a signal peptide can optionally be included at the amino terminus of the enzymes whose native sequences do not include a signal peptide.

In yet another embodiment, the serine protease can be Sep1 from another  Bacillus firmus  strain, such as SEQ ID NO: 211. 
     For serine protease enzymes described herein, sequence identity is determined by aligning the entire length of the sequences in such a way as to obtain optimal matching so that the minimal number of edit operations (e.g., inserts, deletions and substitutions) are needed in order to transform the one sequence into an exact copy of the other sequence being aligned. The Needleman-Wünsch Global Alignmment of Protein Sequences, which is an algorithm that is available through the U.S National Library of Medicine&#39;s National Center for Biotechnology Information (“NCBI”) website, is one example of such analysis. 
     Alternatively or in addition, the enzyme having serine protease activity can comprise an amino acid sequence having at least 70% identity to any one of SEQ ID NOs: 210-211.

     The enzyme having serine protease activity can comprise an amino acid sequence having 100% identity to any one of SEQ ID NOs: 210-211. 
     For example, the enzyme can comprise SEQ ID NOs: 210-211. 
     Alternatively, the enzyme can consist of SEQ ID NOs: 210-211. 
     Additionally, or alternatively, the enzyme having serine protease activity can comprise an amino acid sequence having at least one amino acid deletion relative to the sequence of a wild-type serine protease enzyme from a  Bacillus firmus  bacterium, wherein the amino acid deletion retains the catalytic residues of the wild-type enzyme and results in the same or increased serine protease activity as compared to the serine protease activity of the wild-type serine protease enzyme under the same conditions. In one embodiment the wild-type serine protease enzyme is Sep1 from  Bacillus firmus  DS-1. See Geng, et al., 2016, above. 
     In one embodiment, the enzyme has increased serine protease activity as compared to the serine protease activity of the wild-type serine protease enzyme under the same conditions. 
     For example, the amino acid sequence of the enzyme can comprise SEQ ID NO: 212. 
     Alternatively or in addition, the enzyme having serine protease activity can comprise an amino acid sequence having at least 70% identity to SEQ ID NO: 212. 
     For example, the enzyme having serine protease activity can comprise an amino acid sequence having at least 75% identity to SEQ ID NO: 212.

     Alternatively, the enzyme can consist of SEQ ID NO: 212. 
     In addition, the enzyme having serine protease activity and having 70%, 75%, 80%, 85%, 90%, 95%, 98%, or 99% sequence identity to SEQ ID NO: 212 maintains the deletion in SEQ ID NO: 212 (of amino acid 181-240 of SEQ ID NO: 211). 
     Optional Inclusion of Signal Peptides in the Fusion Proteins 
     In any of the fusion proteins described herein, the enzyme having serine protease activity can further comprise a signal peptide. 
     Where the signal peptide is present, it is preferably present at the amino terminus of the enzyme having serine protease activity. 
     The signal peptide preferably immediately precedes the first amino acid of the enzyme having serine protease activity. 
     Where the fusion protein comprises a signal peptide, the signal peptide can be present at the amino terminus of the enzyme having serine protease activity. 
     D. Methods for Making the Fusion Proteins 
     Any of the fusion proteins described herein can be made using standard cloning and molecular biology methods known in the art. For example, a gene encoding a protein or peptide of interest (e.g., an enzyme having serine protease activity) can be amplified by polymerase chain reaction (PCR) and ligated to DNA coding for any of the targeting sequences, exosporium proteins, or exosporium protein fragments described herein, to form a DNA molecule that encodes the fusion protein. The DNA molecule encoding the fusion protein can be cloned into any suitable vector, for example a plasmid vector. The vector suitably comprises a multiple cloning site into which the DNA molecule encoding the fusion protein can be easily inserted. The vector also suitably contains a selectable marker, such as an antibiotic resistance gene, such that bacteria transformed, transfected, or mated with the vector can be readily identified and isolated. Where the vector is a plasmid, the plasmid suitably also comprises an origin of replication. Alternatively, DNA coding for the fusion protein can be integrated into the chromosomal DNA of the  B. cereus  family member or spore-forming bacterium host. 
     E. Tags, Markers, and Linkers that can be Included in the Fusion Proteins 
     Any of the fusion proteins described herein can also comprise additional polypeptide sequences that are not part of the targeting sequence, exosporium protein, exosporium protein fragment, or the enzyme having serine protease activity. For example, the fusion protein can include tags or markers to facilitate purification or visualization of the fusion protein (e.g., a polyhistidine tag or a fluorescent protein such as GFP or YFP) or visualization of recombinant  Bacillus cereus  family member spores expressing the fusion protein. 
     Expression of fusion proteins on the exosporium of a  Bacillus cereus  family member using the targeting sequences, exosporium proteins, and exosporium protein fragments described herein is enhanced due to a lack of secondary structure in the amino-termini of these sequences, which allows for native folding of the fused proteins and retention of activity. Proper folding can be further enhanced by the inclusion of a short amino acid linker between the targeting sequence, exosporium protein, exosporium protein fragment, spore coat protein, and the enzyme having serine protease activity. 
     Thus, any of the fusion proteins described herein can comprise an amino acid linker between the targeting sequence, the exosporium protein, or the exosporium protein fragment and the enzyme having serine protease activity. 
     The linker can comprise a polyalanine linker or a polyglycine linker. A linker comprising a mixture of both alanine and glycine residues can also be used. Examples of polyalanine linkers are provided as SEQ ID NOs: 208 and 209. 
     For example, in a fusion protein where the targeting sequence comprises SEQ ID NO: 1, a fusion protein can have one of the following structures: 
     No linker: SEQ ID NO: 1-POI 
     Alanine Linker: SEQ ID NO: 1-A n -POI 
     Glycine Linker: SEQ ID NO: 1-G n -POI 
     Mixed Alanine and Glycine Linker: SEQ ID NO: 1-(A/G) n -POI where A n , G n , and (A/G) n  are any number of alanines, any number of glycines, or any number of a mixture of alanines and glycines, respectively. For example, n can be 1 to 25, and is preferably 6 to 10. Where the linker comprises a mixture of alanine and glycine residues, any combination of glycine and alanine residues can be used. In the above structures, “POI” stands for “protein of interest” and represents the enzyme having serine protease activity. 
     Alternatively or in addition, the linker can comprise a protease recognition site. Inclusion of a protease recognition site allows for targeted removal, upon exposure to a protease that recognizes the protease recognition site, of the enzyme having serine protease activity. 
     Where the fusion protein comprises both a linker and signal peptide, the linker would typically be amino-terminal to the signal peptide. For example, where the fusion protein comprises SEQ ID NO: 96, a polyalanine linker, a signal sequence, and the serine protease of SEQ ID NO: 210, these elements would typically be arranged in the following order within the fusion protein, going from the amino-terminus of the fusion protein to the carboxy-terminus: SEQ ID NO: 96-A n -signal sequence-SEQ ID NO: 210. 
     II. Recombinant  Bacillus cereus  Family Members Hosts for Expression of the Fusion Proteins 
     The invention further relates to recombinant  Bacillus cereus  family members that express a fusion protein. The fusion protein can be any of the fusion proteins described in Section I above. 
     The recombinant  Bacillus cereus  family member can comprise any  Bacillus  species that is capable of producing an exosporium. For example, the recombinant  Bacillus cereus  family member can comprise  Bacillus anthracis, Bacillus cereus, Bacillus thuringiensis, Bacillus mycoides, Bacillus pseudomycoides, Bacillus samanii, Bacillus gaemokensis, Bacillus weihenstephensis, Bacillus toyoiensis , or a combination of any thereof. The recombinant  Bacillus cereus  family member suitably comprises  Bacillus thuringiensis  or  Bacillus mycoides.    
     To generate a recombinant  Bacillus cereus  family member expressing a fusion protein, any  Bacillus cereus  family member can be conjugated, transduced, or transformed with a vector encoding the fusion protein using standard methods known in the art (e.g., by electroporation). The bacteria can then be screened to identify transformants by any method known in the art. For example, where the vector includes an antibiotic resistance gene, the bacteria can be screened for antibiotic resistance. Alternatively, DNA encoding the fusion protein can be integrated into the chromosomal DNA of a  B. cereus  family member host. The recombinant  Bacillus cereus  family member can then exposed to conditions which will induce sporulation. Suitable conditions for inducing sporulation are known in the art. For example, the recombinant  Bacillus cereus  family member can be plated onto agar plates, and incubated at a temperature of about 30° C. for several days (e.g., 3 days). 
     Thus, the recombinant  Bacillus cereus  family member can be in the form of a spore. 
     Inactivated strains, non-toxic strains, or genetically manipulated strains of any of the above species can also suitably be used. For example, a  Bacillus thuringiensis  that lacks the Cry toxin can be used. Alternatively or in addition, once the recombinant  B. cereus  family member spores expressing the fusion protein have been generated, they can be inactivated to prevent further germination once in use. Any method for inactivating bacterial spores that is known in the art can be used. Suitable methods include, without limitation, heat treatment, gamma irradiation, x-ray irradiation, UV-A irradiation, UV-B irradiation, chemical treatment (e.g., treatment with glutaraldehyde, formaldehyde, hydrogen peroxide, acetic acid, bleach, or any combination thereof), or a combination thereof. Alternatively, spores derived from nontoxigenic strains, or genetically or physically inactivated strains, can be used. 
     Thus, the recombinant  Bacillus cereus  family member can be in the form of a spore, wherein the spore is inactivated. 
     The recombinant  Bacillus cereus  family member can coexpress two or more of any of the fusion proteins described herein. For example, the recombinant  Bacillus cereus  family member can coexpress at least one fusion protein that comprises SEQ ID NO: 210 together with a fusion protein that comprises SEQ ID NO: 212. 
     Many  Bacillus cereus  family member strains have inherent beneficial attributes. For example, some strains have plant-growth promoting effects. Other strains are endophytic. Some strains are both endophytic and have plant-growth promoting effects. 
     Thus, any of the recombinant  Bacillus cereus  family members described herein can comprise a plant-growth promoting strain of bacteria, an endophytic strain of bacteria, or a strain of bacteria that is both plant-growth promoting and endophytic. 
     The plant-growth promoting strain of bacteria can comprise a strain of bacteria that produces an insecticidal toxin (e.g., a Cry toxin), produces a fungicidal compound (e.g., a β-1,3-glucanase, a chitosanase, a lyticase, or a combination of any thereof), produces a nematocidal compound (e.g., a Cry toxin), produces a bacteriocidal compound, is resistant to one or more antibiotics, comprises one or more freely replicating plasmids, binds to plant roots, colonizes plant roots, forms biofilms, solubilizes nutrients, secretes organic acids, or any combination thereof. 
     The recombinant  Bacillus cereus  family member can comprises an endophytic strain of bacteria. 
     The recombinant  Bacillus cereus  family member can comprise an inactivating mutation in its BclA gene, its CotE gene, or its CotO gene (e.g., a knock-out of the BclA gene, CotE gene, or CotO gene). For example, the recombinant  Bacillus cereus  family member can comprise an inactivating mutation in its BclA gene (e.g., a knock-out of the BclA gene). It has been found that expression of fusion proteins in a recombinant  Bacillus cereus  family member having such a mutation results in increased expression levels of the fusion protein. 
     Compositions of the present invention include cultures, such as whole broth cultures, of the strains described herein. The term culture refers to a population of cells growing in the absence of other species in a predetermined culture media under controlled laboratory or manufacturing conditions. Biologically pure cultures of the recombinant  Bacillus cereus  family members of the present invention may be obtained according to methods well known in the art. 
     Conventional large-scale microbial culture processes include submerged fermentation, solid state fermentation, or liquid surface culture. During the fermentation, as nutrients are depleted, cells begin the transition from growth phase to sporulation phase, such that the final product of fermentation is largely spores, metabolites and residual fermentation medium. Sporulation is part of the natural life cycle of  Bacillus cereus  family members and is generally initiated by the cell in response to stressful environmental conditions, such as nutrient limitation. Fermentation is configured to obtain high levels of colony forming units and to promote sporulation. The bacterial cells, spores and metabolites in culture media resulting from fermentation may be used directly or concentrated by conventional industrial methods, such as centrifugation or filtration such as tangential-flow filtration or depth filtration, and evaporation. 
     Compositions of the present invention include the products of the microbial culture processes described herein. In embodiments in which submerged fermentation is used as the culture process, the product is referred to as a “fermentation broth” or a “whole broth culture.” Such broth may be concentrated, as described above. The concentrated fermentation broth may be washed, for example, via a diafiltration process, to remove residual fermentation broth and metabolites. The term “broth concentrate,” as used herein, refers to fermentation broth that has been concentrated by conventional industrial methods, as described above, but remains in liquid form. The term “fermentation product,” as used herein, refers to fermentation broth or whole broth culture, broth concentrate and/or dried fermentation broth or broth concentrate. 
     The fermentation broth or broth concentrate can be dried with or without the addition of carriers using conventional drying processes or methods such as spray drying, freeze drying, tray drying, fluidized-bed drying, drum drying, or evaporation. The term “fermentation product,” as used herein, refers to fermentation broth or whole broth culture, broth concentrate and/or dried fermentation broth or broth concentrate. 
     The resulting dry products may be further processed, such as by milling or granulation, to achieve a specific particle size or physical format. Carriers, described below, may also be added post-drying. 
     Cell-free preparations of fermentation broth of the strains of the present invention can be obtained by any means known in the art, such as extraction, centrifugation and/or filtration of fermentation broth. Those of skill in the art will appreciate that so-called cell-free preparations may not be devoid of cells but rather are largely cell-free or essentially cell-free, depending on the technique used (e.g., speed of centrifugation) to remove the cells. The resulting cell-free preparation may be dried and/or formulated with components that aid in its application to plants or to plant growth media. Concentration methods and drying techniques described above for fermentation broth are also applicable to cell-free preparations. 
     As described further below in Section IV, the recombinant  Bacillus cereus  family member can comprise a mutation or other modification that allows for collection of exosporium fragments comprising the fusion proteins from spores of the recombinant  Bacillus cereus  family member. 
     III. Promoters for Expression of Fusion Proteins in Recombinant  Bacillus cereus  Family Members 
     The DNA encoding the fusion proteins used in the recombinant  Bacillus cereus  family members, exosporium fragments, formulations, plant seeds, and methods, described herein is suitably under the control of a sporulation promoter which will cause expression of the fusion protein on the exosporium of a  B. cereus  family member endospore (e.g., a native bclA promoter from a  B. cereus  family member). 
     Thus, any of the fusion proteins described above in Section I can be expressed in the recombinant  Bacillus cereus  family member under the control of a sporulation promoter that is native to the targeting sequence, exosporium protein, or exosporium protein fragment of the fusion protein, or a portion of such a promoter. 
     Any of the fusion proteins can be expressed under the control of a high-expression sporulation promoter. 
     The high-expression sporulation promoter can comprise a sigma-K sporulation-specific polymerase promoter sequence. 
     For ease of reference, illustrative nucleotide sequences for promoters that can be used to express any of the fusion proteins in a recombinant  Bacillus cereus  family member are provided in Table 3 below, together with their SEQ ID NOs. Table 3 also provides illustrative minimal promoter sequences for many of the promoters. In Table 3, sigma-K sporulation-specific polymerase promoter sequences in the promoters are indicated by bold and underlined text. Several of the sequences have multiple sigma K sequences that overlap with one another. The overlaps are indicated by double underlining in the table. The promoter sequences are immediately upstream of the start codon for each of the indicated genes. In other words, in the sequences shown in Table 3 below, the last nucleotide of the promoter sequence immediately precedes the first nucleotide of the start codon for the coding region of the gene encoding the indicated protein.

     The sigma-K sporulation-specific polymerase promoter sequences in the promoter sequences shown in Table 3 result in high expression levels of the fusion protein during late sporulation. The consensus sequence for the sigma-K sporulation-specific polymerase promoter sequence is CATANNNTN (SEQ ID NO: 200); however, this sequence can comprise up to two mutations and still be functional. The sigma-K sporulation-specific polymerase promoter sequence is generally found upstream of the ribosome binding site (RBS). 
     Promoters having a high degree of sequence identity to any of the sequences shown above in Table 3 can also be used to express the fusion proteins. 
     For example, the fusion protein can be expressed under the control of a promoter comprising a nucleic acid sequence having at least 80% identity with a nucleic acid sequence of any one of SEQ ID NOs: 37-42 and 123-191. 
     The fusion protein can be expressed under the control of a promoter comprising a nucleic acid sequence having at least 85% identity with a nucleic acid sequence of any one of SEQ ID NOs: 37-42 and 123-191. 
     The fusion protein can be expressed under the control of a promoter comprising a nucleic acid sequence having at least 90% identity with a nucleic acid sequence of any one of SEQ ID NOs: 37-42 and 123-191. 
     The fusion protein can be expressed under the control of a promoter comprising a nucleic acid sequence having at least 95% identity with a nucleic acid sequence of any one of SEQ ID NOs: 37-42 and 123-191. 
     The fusion protein can be expressed under the control of a promoter comprising a nucleic acid sequence having at least 98% identity with a nucleic acid sequence of any one of SEQ ID NOs: 37-42 and 123-191. 
     The fusion protein can be expressed under the control of a promoter comprising a nucleic acid sequence having at least 99% identity with a nucleic acid sequence of any one of SEQ ID NOs: 37-42 and 123-191. 
     The fusion protein can be expressed under the control of a promoter comprising a nucleic acid sequence having 100% identity with a nucleic acid sequence of any one of SEQ ID NOs: 37-42 and 123-191. 
     For example, fusion protein can be expressed under the control of a BclA promoter (e.g., SEQ ID NO: 149, 150, 175, 189, or 190), a CotY promoter (e.g., SEQ ID NO: 41, 42, or 181), an ExsY promoter (e.g., SEQ ID NO: 37, 38, or 180), or a rhamnose promoter (e.g., SEQ ID NO: 185), or a promoter having a high degree of sequence identity to any of these promoters. 
     Thus, for example, the fusion protein can be expressed under the control of a promoter comprising a nucleic acid sequence having at least 80% identity with a nucleic acid sequence of any one of SEQ ID NOs: 37, 38, 41, 42, 149, 150, 175, 180, 181, 185, 189, or 190. 
     The fusion protein can be expressed under the control of a promoter comprising a nucleic acid sequence having at least 85% identity with a nucleic acid sequence of any one of SEQ ID NOs: 37, 38, 41, 42, 149, 150, 175, 180, 181, 185, 189, or 190. 
     The fusion protein can be expressed under the control of a promoter comprising a nucleic acid sequence having at least 90% identity with a nucleic acid sequence of any one of SEQ ID NOs: 37, 38, 41, 42, 149, 150, 175, 180, 181, 185, 189, or 190. 
     The fusion protein can be expressed under the control of a promoter comprising a nucleic acid sequence having at least 95% identity with a nucleic acid sequence of any one of SEQ ID NOs: 37, 38, 41, 42, 149, 150, 175, 180, 181, 185, 189, or 190. 
     The fusion protein can be expressed under the control of a promoter comprising a nucleic acid sequence having at least 98% identity with a nucleic acid sequence of any one of SEQ ID NOs: 37, 38, 41, 42, 149, 150, 175, 180, 181, 185, 189, or 190. 
     The fusion protein can be expressed under the control of a promoter comprising a nucleic acid sequence having at least 99% identity with a nucleic acid sequence of any one of SEQ ID NOs: 37, 38, 41, 42, 149, 150, 175, 180, 181, 185, 189, or 190. 
     The fusion protein can be expressed under the control of a promoter comprising a nucleic acid sequence having 100% identity with a nucleic acid sequence of any one of SEQ ID NOs: 37, 38, 41, 42, 149, 150, 175, 180, 181, 185, 189, or 190. 
     The fusion protein can be expressed under the control of a promoter comprising a sigma-K sporulation specific polymerase promoter sequence, wherein the sigma-K sporulation-specific polymerase promoter sequence or sequences have 100% identity with the corresponding nucleotides of any of SEQ ID NOs: 37-42 and 123-191. 
     The fusion proteins can be expressed under the control of a promoter that is native to the targeting sequence, exosporium protein, or exosporium protein fragment of the fusion protein. Thus, for example, where the targeting sequence is derived from BclA, the fusion protein can be expressed under the control of a native BclA promoter (e.g., SEQ ID NO: 149, 150, 175, 189 or 190). 
     Table 3 also provides illustrative minimal promoter sequences. The fusion proteins can be expressed under any of these minimal promoter sequences. 
     Furthermore, the fusion protein can be expressed under a portion of any of the promoters listed above in Table 3, so long as the portion of the promoter includes a sigma-K sporulation-specific polymerase promoter sequence. For example, the fusion protein can be expressed under a promoter region that comprises the first 25, 50, 100, 150, 200, 250, or 300 nucleotides upstream of the start codon, so long as that region comprises a sigma-K sporulation-specific polymerase promoter sequence. 
     IV. Mutations and Other Genetic Alterations to Recombinant  Bacillus cereus  Family Members that Allow for Collection of Free Exosporium and Exosporium Fragments Derived from Such Recombinant  Bacillus cereus  Family Members 
     As is described further hereinbelow, the recombinant  Bacillus cereus  family members that express fusion proteins comprising a protein or peptide of interest (e.g., an enzyme having serine protease activity) and a targeting sequence, an exosporium protein, or an exosporium protein fragment that targets the fusion protein to the exosporium of the recombinant  Bacillus cereus  family member can be used for various purposes, including delivering the proteins or peptides of interest plants, seeds, a plant growth medium, or an area surrounding a seed or a plant (e.g., via soil drench, foliar application, or as a seed treatment). However, in some cases, the presence of the living microorganisms may not be desirable, and instead, it would be desirable to separate the living spore from the fusion proteins in the exosporium on the outside surface of the spore. For example, in some applications it will be desirable to increase enzyme activity without concern for spore integrity. In such situations, use of exosporium fragments that have been separated from the spores may be preferred over the use of living microorganisms having the enzyme on their exosporium. 
     In addition, for some uses, it may be desirable to reduce the density of the product. In such instances, it would be desirable to separate the dense spore from the exosporium (containing the fusion proteins). Furthermore, under some circumstances the presence of live spores would lead to potential for bacterial growth in a product, which would be undesirable for some applications. 
     Mutations or other genetic alterations (e.g., overexpression of a protein) can be introduced into the recombinant  Bacillus cereus  family members that allow free exosporium to be separated from spores of the recombinant  Bacillus cereus  family member. This separation process yields exosporium fragments that contain the fusion proteins but that are substantially free of the spores themselves. By “substantially free of spores” it is meant that once the free exosporium is separated from the spores, a preparation is obtained that contains less than 5% by volume of spores, preferably less than 3% by volume of spores, even more preferably less than 1% by volume of spores, and most preferably contains no spores or if spores are present, they are undetectable. These exosporium fragments can be used in place of the recombinant  Bacillus cereus  family members themselves in any of the formulations, plant seeds, and methods described herein. 
     Exosporium fragments derived from spores of a recombinant  Bacillus cereus  family member can be used in any of the formulations, plant seeds, and methods described herein. The recombinant  Bacillus cereus  family member expresses any of the fusion proteins described herein. The recombinant  Bacillus cereus  family member also comprises a mutation or expresses a protein, wherein the expression of the protein is increased as compared to the expression of the protein in a wild-type  Bacillus cereus  family member under the same conditions. The mutation or the increased expression of the protein results in  Bacillus cereus  family member spores having an exosporium that is easier to remove from the spore as compared to the exosporium of a wild-type spore. 
     The recombinant  Bacillus cereus  family member: (i) can comprise a mutation in a CotE gene; (ii) can express an ExsY protein, wherein the expression of the ExsY protein is increased as compared to the expression of the ExsY protein in a wild-type  Bacillus cereus  family member under the same conditions, and wherein the ExsY protein comprises a carboxy-terminal tag comprising a globular protein; (iii) can express a BclB protein, wherein the expression of the BclB protein is increased as compared to the expression of the BclB protein in a wild-type  Bacillus cereus  family member under the same conditions; (iv) can express a YjcB protein, wherein the expression of the YjcB protein is increased as compared to the expression of the YjcB protein in a wild-type  Bacillus cereus  family member under the same conditions; (v) can comprise a mutation in an ExsY gene; (vi) can comprise a mutation in a CotY gene; (vii) can comprise a mutation in an ExsA gene; or (viii) can comprise a mutation in a CotO gene. 
     The recombinant  Bacillus cereus  family member can comprise a mutation in the CotE gene, such as a knock-out of the CotE gene or a dominant negative form of the CotE gene. The mutation in the CotE gene can partially or completely inhibit the ability of CotE to attach the exosporium to the spore. 
     The recombinant  Bacillus cereus  family member can express an ExsY protein. The ExsY protein comprises a carboxy-terminal tag comprising a globular protein (e.g., a green fluorescent protein (GFP) or a variant thereof), and the expression of the ExsY protein is increased as compared to the expression of the ExsY protein in a wild-type  Bacillus cereus  family member under the same conditions. The globular protein can have a molecular weight of between 25 kDa and 100 kDa. Expression of the ExsY protein comprising the carboxy-terminal tag comprising a globular protein can inhibit binding of the ExsY protein to its targets in the exosporium. 
     The recombinant  Bacillus cereus  family member can express a BclB protein. Expression of the BclB protein can result in the formation of a fragile exosporium. The expression of the BclB protein can be increased as compared to the expression of the BclB protein in a wild-type  Bacillus cereus  family member under the same conditions. 
     The recombinant  Bacillus cereus  family member can express a YjcB protein. Expression of the YjcB protein can cause the exosporium to form in pieces rather than in a complete structure. The expression of the YjcB protein can be increased as compared to the expression of the YjcB protein in a wild-type  Bacillus cereus  family member under the same conditions. 
     The recombinant  Bacillus cereus  family member can comprise a mutation an ExsY gene, such as a knock-out of the ExsY gene. The mutation in the ExsY gene can partially or completely inhibit the ability of ExsY to complete the formation of the exosporium or attach the exosporium to the spore. 
     The recombinant  Bacillus cereus  family member can comprise a mutation a CotY gene, such as a knock-out of the CotY gene. The mutation in the CotY gene can result in the formation of a fragile exosporium. 
     The recombinant  Bacillus cereus  family member can comprise a mutation an ExsA gene, such as a knock-out of the ExsA gene. The mutation in the ExsA gene can result in the formation of a fragile exosporium. 
     The recombinant  Bacillus cereus  family member can comprise a mutation a CotO gene, such as a knock-out of the CotO gene or a dominant negative form of the CotO gene. The mutation in the CotO gene can cause the exosporium to form in strips. 
     For ease of reference, descriptions of illustrative sequences for CotE, ExsY, BclB, YjcB, CotY, ExsA, and CotO are provided in Table 4 below.

     Exosporium fragments can be prepared from any of these recombinant  Bacillus cereus  family members and used for various purposes as described further herein below. Where the recombinant  Bacillus cereus  family member expresses a fusion protein, the exosporium fragments will comprise the fusion proteins. Upon purification of the exosporium fragments that contain the fusion proteins from the spores, a cell-free protein preparation is obtained in which the fusion proteins are stabilized and supported through covalent bonds to the exosporium fragments. 
     To remove the exosporium from spores of the recombinant  Bacillus cereus  family members that have mutations or other genetic alterations that allow for collection of free exosporium, a suspension or fermentation broth of the spores can be subjected to centrifugation or filtration to produce fragments of exosporium that are separated from the spores. Where the recombinant  Bacillus cereus  family member expresses a fusion protein, the exosporium fragments will comprise the fusion protein. 
     A suspension or fermentation broth comprising the spores can be subjected to centrifugation, followed by collection of the supernatant. The supernatant comprises the fragments of the exosporium and is substantially free of spores. 
     Alternatively, a suspension or fermentation broth comprising the spores can be subjected to filtration, followed by collection of the filtrate. The filtrate comprises the fragments of the exosporium and is substantially free of spores. 
     The suspension or fermentation broth of spores can be agitated or mechanically disrupted prior to centrifugation or filtration. 
     The exosporium fragments can also be separated from the spores by gradient centrifugation, affinity purification, or by allowing the spores to settle out of the suspension. 
     Due to the strong covalent bonds between the fusion proteins and the exosporium fragments, the fusion proteins become resistant to heat. The heat resistance of the fusion proteins bound to the exosporium fragments allows them to be used for applications that require heat-resistant proteins or enzymes. 
     Exosporium fragments derived from a recombinant  Bacillus cereus  family member are provided. 
     The exosporium fragments can be derived from any of the recombinant  Bacillus cereus  family members that comprise any of the mutations or other genetic alterations described herein that allow for collection of free exosporium. 
     The exosporium fragments can comprise any of the fusion proteins described above in Section I. 
     V. Formulations 
     A formulation is provided. The formulation comprises any of the recombinant  Bacillus cereus  family members described herein. The formulation further comprises an agriculturally acceptable carrier. 
     Another formulation is provided. The formulation comprises exosporium fragments derived from any of the recombinant  Bacillus cereus  family members described herein. The formulation further comprises an agriculturally acceptable carrier. 
     VI. Treated Seeds 
     A treated plant seed is provided. The plant seed can be treated with any of the recombinant  Bacillus cereus  family members described herein. The recombinant  Bacillus cereus  family member can express any of the fusion proteins described herein. 
     Another treated plant seed is provided. The plant seed can be treated with any of the exosporium fragments described herein. The exosporium fragments can be derived from any of the  Bacillus cereus  family members described herein. The exosporium fragments can comprise any of the fusion proteins described herein. 
     Yet another treated plant seed is provided. The plant seed can be treated with any of the formulations described herein. 
     In any of the treated plant seeds, the plant seed can be coated with the recombinant  Bacillus cereus  family member, the exosporium fragments, or the formulation. 
     The recombinant  Bacillus cereus  family members, exosporium fragments, or formulations can used as seed treatments, e.g., seed coatings or dressings. Seed coating or dressing formulations may be in the form of a liquid carrier formulation, a slurry formulation, or a powder formulation. 
     Seed coating or dressing formulations can be applied with conventional additives that are provided to make the seed treatment have sticky qualities to stick to and coat the seeds. Suitable additives comprise: talcs, graphites, gums, stabilizing polymers, coating polymers, finishing polymers, slip agents for seed flow and plantability, cosmetic agents, and cellulosic materials such as carboxymethyl cellulose and the like. 
     The seed treatments formulations can further comprise colorant agents and/or other additives. 
     The seed treatment formulations(s) may be applied to seeds in a suitable carrier such as water or a powder. The seeds can then be allowed to dry and planted in conventional fashion. The recombinant  Bacillus cereus  family members or exosporium fragments can be applied directly to the seed as a solution or in combination with other commercially available additives. For example, the recombinant  Bacillus cereus  family members or exosporium fragments can be applied in combination with seedling-acceptable carrier(s) (e.g., a liquid carrier or a solid carrier). 
     Solutions containing the recombinant  Bacillus cereus  family members or exosporium fragments can be sprayed or otherwise applied to the seed (e.g., in a seed slurry or a seed soak). 
     Solid or dry materials containing recombinant  Bacillus cereus  family members or exosporium fragments are also useful to promote effective seedling germination, growth, and protection during early seedling establishment. 
     The recombinant  Bacillus cereus  family members or exosporium fragments can be used with a solubilizing carrier such as water, a buffer (e.g., citrate or phosphate buffer), other treating agents (e.g., alcohol or another solvent), and/or any soluble agent. 
     In addition, small amounts of drying agent enhancers, such as lower alcohols, etc. can be used in seed coating formulations. 
     Surfactants, emulsifiers and preservatives can also be added at relatively low (e.g., about 0.5% w/v or less) levels in order to enhance the stability of the seed coating product. 
     Seeds can be treated using a variety of methods including, but not limited to, pouring, pumping, drizzling, or spraying an aqueous solution containing the recombinant  Bacillus cereus  family members or exosporium fragments on or over a seed; or spraying or applying the recombinant  Bacillus cereus  family members or exosporium fragments onto a layer of seeds either with or without the use of a conveyor system. 
     Mixing devices useful for seed treatment include but are not limited to tumblers, mixing basins, mixing drums, and fluid application devices that include basins or drums used to contain the seed while coating. 
     After seed treatment, the seed may be air-dried or a stream of dry air may be optionally used to aid in the drying of the seed coatings. 
     Seed treatments containing the recombinant  Bacillus cereus  family members or exosporium fragments can be applied using any commercially available seed treatment machinery or can also be applied using any acceptable non-commercial method(s) such as the use of syringes or any other seed treatment device.

Suitable genetically modified seeds include those of cole crops, vegetables, fruits, trees, fiber crops, oil crops, tuber crops, coffee, flowers, legume, cereals, as well as other plants of the monocotyledonous and dicotyledonous species. Preferably, the genetically modified seeds include peanut, tobacco, grasses, wheat, barley, rye, sorghum, rice, rapeseed, sugarbeet, sunflower, tomato, pepper, bean, lettuce, potato, and carrot. Most preferably, the genetically modified seeds include cotton, soybean, and corn (sweet, field, seed, or popcorn). 
     Particularly useful transgenic plants which may be treated according to the invention are plants containing transformation events, or a combination of transformation events, that are listed for example in the databases from various national or regional regulatory agencies (see for example http://gmoinfo.jrc.it/gmp_browse.aspx and http://www.agbios.com/dbase.php). 
     Having described the invention in detail, it will be apparent that modifications and variations are possible without departing from the scope of the invention defined in the appended claims. 
     Examples 
     The following non-limiting examples are provided to further illustrate the present invention. 
     Example 1. Construction of a  Bacillus cereus  Family Member Displaying a Serine Protease or Serine Protease Variant 
     To construct a  Bacillus cereus  family member displaying the serine protease of SEQ ID NO: 210 or SEQ ID NO: 211 or the serine protease variant of SEQ ID NO: 212, the pSUPER plasmid was generated through fusion of the pUC57 plasmid (containing an ampicillin resistance cassette and a ColE1 origin of replication) with the pBC16-1 plasmid from  Bacillus cereus  (containing a tetracycline resistance gene, repU replication gene and oriU origin of replication). This 5.8 kb plasmid can replicate in both  E. coli  and  Bacillus  spp. and can be selected by conferring resistance to ρ3-lactam antibiotics in  E. coli  and resistance to tetracycline in  Bacillus  spp. The basal pSUPER plasmid was modified by insertion of a PCR-generated fragment that fused the BclA promoter (SEQ ID NO: 149), a start codon, amino acids 20-35 of BclA (amino acids 20-35 of SEQ ID NO: 1) and an alanine linker sequence in frame with SEQ ID NO: 210, SEQ ID NO: 211, or SEQ ID NO: 212, resulting in a plasmid termed pSUPER-BclA 20-35-SEQ ID NO: 210, pSUPER-BclA 20-35-SEQ ID NO: 211, or pSUPER-BclA 20-35-SEQ ID NO: 212, respectively. This construct was transformed into  E. coli  and plated on Lysogeny broth plates plus ampicillin (100 μg/mL) to obtain single colonies. Individual colonies were used to inoculate Lysogeny broth plus ampicillin and incubated overnight at 37° C., 300 rpm. Plasmids from resulting cultures were extracted using a commercial plasmid purification kit. DNA concentrations of these plasmid extracts were determined via spectrophotometry, and obtained plasmids subjected to analytical digests with appropriate combinations of restriction enzymes. The resulting digestion patterns were visualized by agarose gel electrophoresis to investigate plasmid size and presence of distinct plasmid features. Relevant sections, such as the SEQ ID NO: 210, SEQ ID NO: 211 or SEQ ID NO: 212 expression cassette, of the purified pSUPER derivatives were further investigated by Sanger sequencing. 
     Additionally and alternatively, a derivative plasmid of the pSUPER plasmids described above was created as follows. The pBC fragment (pBC16-1-derived section of pSUPER including BclA/serine protease variant expression cassette and tetracycline resistance) of the pSUPER plasmids described above was amplified by PCR and subsequently circularized by blunt-end ligation. 
     pSUPER, verified as described above, and pBC plasmid ligations were introduced by electroporation into  Bacillus thuringiensis  BT013A. Single transformed colonies were isolated by plating on nutrient broth plates containing tetracycline (10 μg/mL). Individual positive colonies were used to inoculate brain heart infusion broth containing tetracycline (10 μg/mL) and incubated overnight at 30° C., 300 rpm. Genomic DNA of resulting cultures was purified and relevant sections of the pSUPER plasmid or the pBC plasmid were re-sequenced to confirm genetic purity of the cloned sequences and, for pBC, the correct ligation site. Verified colonies were grown overnight in brain heart infusion broth with 10 μg/mL tetracycline and induced to sporulate through incubation in a yeast extract-based media at 30° C. for 48 hours. Short names for BT013A carrying the above-described plasmids are described in Table 5, below. 
       Bacillus thuringiensis  BT013A was deposited with the United States Department of Agriculture (USDA) Agricultural Research Service (ARS), having the address 1815 North University Street, Peoria, Ill. 61604, U.S.A., on Mar. 10, 2014, and assigned accession number NRRL B-50924.  Bacillus thuringiensis  BT013A is also known as  Bacillus thuringiensis  4Q7. 
     Example 2. Construction and Purification of Exosporium Fragments from a  Bacillus cereus  Family Member Expressing Serine Protease Variant 
     Knock Out (KO) Mutants: 
     To make exsY knockout (KO) mutant strains of  Bacillus thuringiensis  BT013A, the plasmid pKOKI shuttle and integration vector was constructed that contained the pUC57 backbone, which is able to replicate in  E. coli , as well as the origin of replication and the erythromycin resistance cassette from pE194. This construct is able to replicate in both  E. coli  and  Bacillus  spp. A construct was made that contained the 1 kb DNA region that corresponded to the upstream region of the exsY gene and a 1 kb region that corresponded to the downstream region of the gene exsY, both of which were PCR amplified from  Bacillus thuringiensis  BT013A. For each construct, the two 1 kb regions were then spliced together using homologous recombination with overlapping regions to each other and with the pKOKI plasmid, respectively. This plasmid construct was verified by digestion and DNA sequencing. Clones were screened for erythromycin resistance. 
     Clones were passaged under high temperature (40° C.) in brain heart infusion broth. Individual colonies were toothpicked onto LB agar plates containing erythromycin 5 μg/mL, grown at 30° C., and screened for the presence of the pKOKI plasmid integrated into the chromosome by colony PCR. Colonies that had an integration event were continued through passaging to screen for single colonies that lost erythromycin resistance (signifying loss of the plasmid by recombination and removal of the exsY gene). Verified deletions were confirmed by PCR amplification and sequencing of the target region of the chromosome. Finally, the PCR-amplified, circularized pBC section of the pSUPER-BclA 20-35 SEQ ID NO: 210 plasmid, pSUPER-BclA 20-35 SEQ ID NO: 211 plasmid or pSUPER-BclA 20-35 SEQ ID NO: 212 plasmid (described above in Example 1) was transformed into this exsY mutant strain of BT013A. 
     For each esxYKO mutant expressing the serine protease of SEQ ID NO: 210 or 211 or the serine protease variant of SEQ ID NO: 212, an overnight culture was grown in BHI media at 30° C., 300 rpm, in baffled flasks with antibiotic selection. One milliliter of this overnight culture was inoculated into a yeast extract-based media (50 mL) in a baffled flask and grown at 30° C. for 2 days. An aliquot of spores was removed and the spores were agitated by vortexing. The spores were collected via centrifugation at 8,000×g for 10 minutes, and supernatant containing the exosporium fragments was filtered through a 0.22 μm filter to remove any residual spores. No spores were found in the filtrate. 
     Short names for BT013AexsYKO carrying the above-described plasmids are described in Table 5, below. 
     Example 3. Use of an Expression Cassette Comprising a Non-Antibiotic Selectable Marker to Express the Serine Protease Variant on the Surface of  Bacillus cerus  Family Member Spores 
     SEQ ID NO: 212 was cloned into a derivative of the pSUPER plasmid described in Example 1. In this derivative, the tetracycline resistance marker had previously been exchanged with a non-antibiotic selectable marker. The pBC fragment of this derivative pSUPER plasmid was created as described in Example 1. The resulting pBC ligation, referred to as pBCnam212, was introduced using electroporation into a  Bacillus thuringiensis  BT013A derivative strain that had been modified to support the use of the non-antibiotic selectable marker. Single colonies of transformations were obtained by plating on suitable selection media on petri plates. Individual colonies were used to inoculate a suitable selection media and incubated overnight at 30° C., 300 rpm. Genomic DNA of resulting cultures was purified and the pBC plasmid re-sequenced to verify genetic purity. Verified colonies were grown overnight in suitable selection media and induced to sporulate through incubation in a yeast extract-based media at 30° C. for 48 hours.

     Example 4. Soybean Growth Room Studies 
     To measure plant growth and development, a growth room assay was conducted. Seeds of two soybean varieties were treated with the whole broth from BT013A-pBCnam212 or the exosporium fragment preparation from BT013AexsYKO-pBC212 along with a chemical base treatment having fungicidal and other pesticidal activities. Control seeds were treated with the chemical base only. Whole broth and the exosporium fragment preparation, respectively, were applied at a rate of 3.6 fluid ounces per cwt, which, for the whole broth was equivalent to 3.8×10 4  colony forming units (“CFU”)/seed. (The same volume of the exosporium fragment preparation as whole broth was applied to seeds to achieve a comparable application rate to that of the whole broth, as very little liquid is lost during the centrifugation and filtration processes that are used to separate exosporium fragments from cells.) To set up the growth room assay, top soil was mixed with sand at a volume ratio of 2:1 inside a cement mixer until homogenous. The soil mixture was then added to small pots (3.5″ L×3.5″ W×4″ D), which were placed into plastic trays, with nine pots per tray. Trays were moved to the growth room trial location. After 48 hours, 50 mL of water was evenly added to each pot. Subsequently, two seed were planted per pot to a depth of 1″ and covered with dry soil mixture. In total, 16 seeds were planted per replicate. Each seed treatment was tested in three replicates per variety. The resulting trays were placed on shelves under high-intensity lights set to a 13-hour light/11-hour dark schedule. Watering was done as needed. No fertilizer was used. The trays were rotated every two days to minimize position effects. Data was gathered from each germinated plant. 
     Height measurements were taken to the corresponding leaf node at the two plant growth milestones cotyledon elongation and unifoliate emergence. These measurements were taken when approximately 50% of the control plants exhibited the corresponding milestone growth stage. Leaf surface area percentage was taken at the unifoliate emergence milestone utilizing the mobile application Canopeo developed at Oklahoma State University (Stillwater, Okla.; (https://appcenter.okstate.edu/content/canopeo). This application utilizes a digital photograph to determine the percentage of the recorded area occupied by plant material. Once the plants were at the second trifoliate growth stage, they were removed from their inserts and dirt adhered to the root structure was removed using water. Post removal of surplus water by padding with paper towels the fresh root biomass was recorded. In each case, results from plants treated with the serine protease construct in addition to the chemical base were normalized to plants in each trial that had received only the chemical base treatment. Table 6 shows the percent increase as compared to the seeds treated with the chemical base only. Results indicate that both treatments enhance plant growth in some manner.

     Example 5. Use of a Recombinant  Bacillus cereus  Family Member Displaying a Serine Protease Variant to Control Soybean Cyst Nematodes 
     Seed were treated with either an insecticide/fungicide (chemical) base or the same chemical base plus 234.8 mL/100 kg of the whole broth culture of BT013A-pBCnam212, which is equivalent to 1×10 10  colony forming units (of the recombinant cell expressing the serine protease variant) (“CFU”)/100 kg seed. Both treatments were planted into a sandy loam soil. Ten days post emergence, soybean plants were inoculated with 2,000 second stage juvenile soybean cyst nematodes ( Heterodera glycine ). Plants were harvested four weeks later and cysts were removed and collected using a system of sieves, centrifugation, and a sucrose solution. Cysts were then crushed to release the eggs which were enumerated by taking three sub-samples from the total solution collected from each of ten plants from each treatment. The Sep1-treated seed showed a reduction in both the total number of nematode eggs and the number of eggs per gram of root, which was calculated by a dry weight of each plants root system post cyst extraction, as shown in Table 7, below. The average eggs/gram root was decreased by over 50% in the Sep1-treated seed.

     Additional experiments were conducted, as above, to test the activity of a whole broth culture of BT013A-pBCnam212 and exosporium fragments of BT013AexsYKO-pBC212, preparation of which is described in Examples 3 and 2, above. All seeds were treated with (i) an insecticide/fungicide (chemical) base as shown in Table 8; (ii) the chemical base of Table 8 with a commercial nematicide (applied at 0.25 mg ai/seed); or (iii) the chemical base of Table 8 and 234.8 mL/100 kg of either the whole broth culture or the exosporium fragment preparation, both expressing the serine protease variant. The concentration of each whole broth culture was 5×10 6  CFU/mL. As noted above, the same volume of the exosporium fragment preparation as whole broth was applied to seeds to achieve a comparable application rate to that of the whole broth, as very little liquid is lost during the centrifugation and filtration processes that are used to separate exosporium fragments from cells. The eggs/gram of root was calculated utilizing the dry weight of the root systems from each sampled plant (as represented in Table 9). Both serine protease constructs performed similarly to the commercial nematicide with regards to reducing the number of SCN eggs recovered per gram of root (˜40%) and increasing root volume (most likely related to reduced nematode pressure).

     Example 6. Use of a Recombinant  Bacillus cereus  Family Member Displaying a Serine Protease Variant or Purified Exosporium to Stimulate Plant Growth in Soybeans 
     Field trials were conducted in soy to test the plant growth promotion capabilities of the whole broth culture of BT013A-pBCnam212 and exosporium fragments of BT013AexsYKO-pBC212, preparation of which is described in Examples 3 and 2, above. The whole broth culture or exosporium fragment preparation, each displaying the serine protease variant of SEQ ID NO: 212, was applied to soybean seed along with a chemical base treatment having fungicidal and pesticidal activities. The whole broth was applied at a rate of 1×10 10  colony forming units (“CFU”)/100 kg seed, which is 234 mL per 100 kg seeds. The same volume of the exosporium fragment preparation as the whole broth was applied to seeds to achieve a comparable application rate to that of the whole broth, as very little liquid is lost during the centrifugation and filtration processes that are used to separate exosporium fragments from cells. Such treated soybean seeds were planted and grown during the normal season until harvest. Table 10, below, shows how the above constructs performed in ten trials, each consisting of four replicates, compared to seeds treated only with the chemical base.

     Example 7. Use of a Recombinant  Bacillus cereus  Family Member Displaying a Serine Protease Variant to Control Soybean Cyst Nematodes, Root Knot Nematodes and Lesion Nematodes—Field Trials 
       Heterodera glyciens  (SCN) Experiment 
     Seed were treated with a commercial insecticide/fungicide base alone or with one of three test treatments including two commercial seed applied nematicides and exosporium fragments from BT013AexsYKO-pBC212, referred to as the “Serine Protease Construct” in the tables below. Application rates for the exosporium fragments are provided in terms of CFU/seed and volume/100 kg seed. This is because when the exosporium fragment preparation is separated from the whole broth from which it was derived, very little liquid is lost during the centrifugation and filtration processes that are used to separate exosporium fragments from cells, so the CFU/seed provides another application rate that is useful when comparing results to other experiments. A total of 140 seed per treatment (Table 1) were hand planted in small strip micro-plots. Four reps (35 seed each) per treatment were arranged in a randomized complete block design. Just prior to planting, five soil core samples (30 cm deep each discarding the top 10 cm) were taken and utilized to create a composite sample for each micro-plot and analyzed to determine the natural SCN population. The average number of SCN juveniles per micro-plot ranged from 402 to 556/100 cc of soil (Table 12). After emergence, each plant was inoculated with a mixture containing 6,200 SCN eggs and juveniles and plants were latter thinned to exactly 30 per micro-plot at the V2 development stage. At 10 weeks (70 DAP), five plants were dug up per plot. Soil was collected and composited from around the root zone of each of the plants and used to determine a count of nematodes/100 cm 3  of soil. The harvested roots were processed (cysts collected, roots dried and weighed) to determine cysts/gram of root. Finally, cysts were crushed and eggs were collected to compare the total eggs recovered/plot. As shown in Table 12, the assessment of the average initial natural population of SCN was similar across all four treatments and the serine protease construct performed similarly (slightly better numerically) to the two commercial nematicides with regards to reducing nematode counts on the roots and in the surrounding soil.

     Micro-plots were created in buried containers (16″ diameter) with fumigated confirmed nematode free soil at planting. Two separate experiments were conducted, one with RKN (Table 13) and one with a combination of RKN and SCN (Table 14). Seed of a different variety but with the same treatment list from the previous experiment (Table 11) were hand planted (two per micro-plot) with eight micro-plots/reps per treatment for each trial arranged in a randomized complete block design. Half of micro-plots (32) were inoculated with RKN eggs and the other half with a mix of RKN and SCN eggs between the VC and VE development stages. Thirty days after inoculation, four mico-plots per treatment/per experiment were taken down and the two plants recovered were given a composite qualitative gall rating (0-best to 6-worst). Soil samples were also collected from around the harvested plants to create 4 individual composite samples which were analyzed for nematodes per 100 cm 3  of soil. The remaining micro-plots were then harvested 30 days later (60 days after inoculation). The same procedures were used to perform gall ratings on all remaining plants and finally the dug roots were composited and analyzed to determine RKN per gram of root in the first experiment and RKN and SCN per gram of root in the co-inoculate experiment. As shown in Table 13 and Table 14, the serine protease construct performed as good (or better) than the two commercial nematicides with regards to reducing both RKN and SCN populations in both the soil and on the roots of treated plants.

       Pratylenchus —Lesion Nematode Experiments 
     Seed were treated with a commercial insecticide/fungicide base alone or with one of three test treatments including two commercial seed applied nematicides and exosporium fragments from BT013AexsYKO-pBC212, referred to as the “Serine Protease Construct” in the tables below. Seeds treated as described in Table 8 were hand planted and germinated in small pots in a greenhouse and at the VI development stage eight plants per treatment were inoculated with 100 Lesion ( Pratylenchus ) juveniles. Inoculated plants (and the surrounding soil) were transplanted to a field (which was tested and showed no natural lesion population) in a randomized complete block design. Eight weeks later core soil samples were taken from around each test plant to determine the number of nematodes per 100 cm 3  of soil. After soil sampling the individual plants were dug up and 25 g of root tissue was collected from the root tips of each plant. Root tissue was then individually analyzed using a Baermann Funnel procedure to determine the number of Lesion nematodes per gram of root (Table 15). As shown in Table 15, the two commercial nematicides and the serine protease construct had a similar impact on  Pratylenchus  (root lesion) nematodes both in the roots and in the soil surrounding treated plants as compared to the control.

     Example 8. Protease Assays 
     To determine and compare activities of the full length (SEQ ID NOs: 210 and 211) and variant (SEQ ID NO: 212) serine protease enzymes expressed on the exosporium of  Bacillus  spores, a protease assay was performed using a commercial protease kit (Sigma-Aldrich PF0100), which detects a diverse range of proteases, such as serine, cysteine, metallo and aspartic proteases. 
     1 mL of sporulated cultures of BT013A wildtype (7.90×10 7  CFU/mL), BT013A-pBC210, BT013A-pBC211 (each at 4.34×10 7  CFU/mL) and BT013A-pSuper212 (3.40×10 7  CFU/mL) were spun at 8,000×g for 10 min and the supernatant removed. 
     Cells were washed with 1 mL Butterfield&#39;s phosphate buffer, spun again at 8,000×g for 10 minutes, and the supernatant removed. Cell pellets were resuspended in 50 μL (20× concentration) Butterfield&#39;s phosphate buffer. 10 μL of each sample was used for the assay. 
     The assay was performed according to manufacturer&#39;s instructions. Briefly, 10 μL of the three cultures or 10 μL of various concentrations of trypsin, the positive control, were mixed with 20 μL incubation buffer and 20 μL of FITC casein substrate. Each assay was performed in triplicate using the same starting concentrated cell culture. A blank was also prepared by substituting Butterfield&#39;s phosphate buffer as the sample. Samples were incubated in the dark at 37° C. for 4 hr, then 150 μL of 0.6N TCA was added to stop the reaction. Samples were incubated in the dark at 37° C. for an additional 30 min. Samples were centrifuged at 10,000×g for 10 min to pellet precipitate. 10 μL of supernatant was mixed with 1 mL assay buffer and 200 μL was transferred in duplicate to a 96-well black flat bottom assay plate. Fluorescence was measured with excitation at 485 nm and emission at 535 nm. Duplicate values from the plate were averaged and those values used to calculate the average and standard deviation of the triplicate samples. The average of the blank samples was subtracted from the average of the samples containing spores.  FIG. 2  shows the average of triplicate samples with error bars representing the standard deviation. This assay shows that the tested whole broth cultures have protease activity, with additional activity derived from the expressed serine protease of SEQ ID NO: 210 and SEQ ID NO: 212, given the differences in activity between the whole broth from the recombinant  Bacillus cereus  family members expressing the serine protease of SEQ ID NO: 210 and the variant serine protease of SEQ ID NO: 212 and the whole broth from wildtype BT013A. 
     Example 9. Stability of Free and Bound Protein as Measured in Serine Protease Assays 
     Experiments were conducted to compare the stability of serine protease variant enzymes bound to the exosporium of BT013A and of free enzymes. Enzyme solutions were prepared by growing the strains of interest to sporulation (24 hr 30° C. 250 rpm colony inoculated BHI; 48 hr 30° C. 250 rpm 2% seed culture inoculated yeast extract-based media), followed by multiple filtration steps of this whole broth. Strains of interest are BT013AexsYKO-pBC212 (a strain expressing variant serine protease on exosporium fragments) and BT013AexsYKO (a mutant strain without a plasmid that results in exosporium fragments). Whole broth contains the cells of the above two strains and both chromosomally generated endogenous proteins that are secreted and also displayed on the exosporium and plasmid generated serine protease enzymes that are only displayed on the exosporium. The plasmid generated protein in most cases stays on the exosporium, which we refer to as bound protein, and some fall off the exosporium, which we refer to as free. In order to test the stability of the protein in the bound versus free forms, filtration steps were used to separate bound protein versus free. 
     Cells of the strains of interest shed their exosporium layer (due to the ExsY knock-out), resulting in a whole broth that contained exosporium fragments. Whole broth samples were pelleted at 8000×g 10 mins 25° C., pellet discarded, and supernatant flowed through a 0.22 μm filter to remove all cells. The cell free supernatant represents both exosporium bound and free proteins and is referred to as “processed strip”. The processed strip was then filtered through a 50 kd filter, retentate saved, representing the bound protein on strips of the exosporium. The 50 kd filtrate was then filtered through a 3 kd filter, retentate saved, representing the free protein. In order to represent the bound protein stability and the free protein stability as these would occur in the supernatant from a whole broth culture of BT013AexsYKO-pBC212, the background proteins that would be present prior to the filtration were added back to the filtered free and bound protein fractions. To accomplish this, to the exosporium-bound protein (i.e., the 50 kd protein retentate) from the culture of BT013AexsYKO-pBC212 was added a 3 kd retentate from a culture of BT013AexsYKO, normalized to the CFU concentration of the starting whole broth culture for the BT013AexsYKO. Conversely, to the 3kd protein retentate from the culture of BT013AexsYKO-pBC212 was added a 50kd retentate from a culture of BT013AexsYKO, normalized to the CFU concentration of the starting whole broth culture for the BT013AexsYKO. The “Bound” enzymes solutions in the following studies contained 50kd BT013AexsYKO-pBC212+3kd BT013AexsYKO. The “Free” enzyme solutions in the following studies contained 3kd BT013AexsYKO-pBC212+50kd BT013AexsYKO. 
     The temperature stability of Bound and Free enzyme solutions was determined by incubating the crude enzyme solutions described above at different temperatures. The Bound and Free enzyme solutions (50 ml) in test tubes were incubated at specified temperatures (22° C.-80° C.) for 2 hours and stored at 4° C. until used. Protease activities were measured as described below and the percent residual activity was calculated by comparing protease activity of enzymes incubated in different temperature to the activity at 22° C. This experiment was done in triplicate. 
     Sep1 protease activity was determine using synthetic peptide substrate (Ala-Ala-Pro-Phe). The peptide substrate is fused with nitro phenyl at the C-terminus and succinyl group at the N-terminus. The peptide shows absorbance maxima at 320 nm before protease cleavage and shifts to 390 nm following the cleavage. The assay mixture consisted of 10 μl of 2.5 mg/mL peptide substrate in 240 μl of 50 mM Hepes buffer pH 7.5, containing 5 mM CaCl 2 . The substrate and the buffer were pre-incubated at room temperature, followed by the addition of 25 μl of the enzyme solution. The rate of enzymatic activity was monitored in the spectrophotometer as continuous increase of OD at 390 nm. The rate of the enzymatic activity was determined by measuring the initial slope of the curve. Results are shown in  FIG. 3 . This data shows that the bound serine protease enzyme is more stable than the free enzyme. 
     Example 10. Comparison of Activity of Exosporium Fragments in Serine Protease Assays 
     Whole broth cultures of BT013AExsYKO (9.79×10 7  CFU/ml), BT013AExsYKO-pBC210 (7.06×10 7  CFU/ml) and BT013AExsYKO-pBC212 (7.06×10 7  CFU/ml) were grown as described in Example 2 to the CFU concentrations designated after each strain. Exosporium fragment filtrates were generated as described in Example 2, and equal volumes of each were tested as follows. Enzyme activity was determine using synthetic peptide substrate (Ala-Ala-Pro-Phe). The peptide substrate is fused with nitro phenyl at the C-terminus and succinyl group at the N-terminus. The peptide shows absorbance maxima at 320 nm before protease cleavage and shifts to 390 nm following the cleavage. The assay mixture consisted of L of 2.5 mg/mL peptide substrate in 240 μL of 50 mM Hepes buffer pH 7.5, containing 5 mM CaCl 2 . The substrate and the buffer were pre-incubated at room temperature, followed by the addition of 25 μL of the enzyme solution. Results are shown in  FIG. 4 . This data shows that both whole broth cultures have enzymatic activity and BT013AExsYKO-pBC212 has slightly higher activity than does BT013AExsYKO-pBC210. Without wishing to be bound by any theory, Applicant hypothesizes that the recombinant  Bacillus cereus  family member with the variant serine protease (SEQ ID NO: 212) has greater biological activity than the recombinant  Bacillus cereus  family member with the full-length serine protease (SEQ ID NO: 210). 
     Example 11—Use of a Recombinant  Bacillus cereus  Family Member Displaying a Serine Protease or a Serine Protease Variant to Control Soybean Cyst Nematodes 
     All seeds were treated with (i) an insecticide/fungicide base, as shown in Table 16, (ii) the base shown in Table 16 with a commercial nematicide (applied at 0.25 mg ai/seed), or (iii) the base shown in Table 16 and whole broth cultures or exosporium fragment preparations prepared as described in Examples 1 and 2, as listed in Table 17. All biological treatments were applied at 234.8 mL/100 kg of soybean seed. CFU concentrations (CFU/mL) provided in Table 17 below represent CFU of whole broth cultures that were applied to seed or of whole broth cultures from which exosporium fragments were prepared, as described in Example 2. 
     Single seeds from each treatment were planted into individual pots of a sandy loam soil and inoculated with ˜1,500 vermiform  Heterodera glycines  (SCN) eggs seven days after planting. Four weeks later plants and cysts were harvested and utilized to compare the relative cysts/gram of root. The two biological treatments not transformed with a serine protease construct, whole broth culture of BT013A and exosporium fragment preparation of a culture of BT013AexsYKO, had a similar number of cysts as the base treatment, while the four biological treatments containing a serine protease construct had a reduction in cysts similar to the commercial nematicide ( FIG. 5 ).
