DETAILED DESCRIPTION
In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here.
Certain aspects described herein relate to modifying a eukaryotic cell by providing at least one exogenous cellular component. In an embodiment, the exogenous cellular component includes at least one of an exogenous mitochondria, exogenous mitochondrial DNA, DNA of the cell nucleus, or exogenous cell nucleus to the eukaryotic cell. In an embodiment, at least one of the exogenous mitochondria, exogenous mitochondrial DNA, or exogenous cell nucleus is derived from a maternally genetically related cell.
Mitochondria are controlled by a dual genome system (particularly in humans) with cooperation between endogenous mitochondrial genes and mitochondrial genes translocated to the nucleus over the course of evolution. See, for example, Cummins, Human Rep. Update vol. 7, no. 2, pp. 217-228 (2001), which is incorporated herein by reference. Mitochondria likely play a role in aging, apoptosis, metabolism, and many diseases. The mitochondrial genome is highly compact, with little tolerance for mutations. Id. Thus, the ability to construct cells, cell systems, or animal embryos with maternally genetically related mitochondria, mitochondrial DNA, or cell nucleus, will provide powerful tools for biological tissue generation, regeneration, and alleviation of a subject from diseases.
The function of mitochondria by both genes of the nucleus and mitochondrial genes can result in conflict, under certain conditions. Id. For example, genome imprinting occurs where certain genes influencing placental and embryonic development are expressed or suppressed according to whether they pass through paternal or maternal gametogenesis. Id.
The complete mitochondrial sequence is known for more than 58 chordate and 29 non-chordate species. Id. The genome is generally a closed circular molecule with little redundancy, although linear forms with telomere-like terminations are known. Id. Mitochondrial DNA is generally tightly linked to the electron transport system and is vulnerable to damage since certain components mutate up to 100 times more rapidly than DNA of the cell nucleus. Id.
It has been published that cell lines can be constructed devoid of endogenous mitochondrial DNA (mtDNA), and re-populated with xenogenic mitochondrial lineages, which demonstrates that survival of mitochondrial genotypes is dependent on the nucleus background. Id. Furthermore, it has been published that rat mtDNA can restore translation but not respiration in mtDNA-depleted mouse cell lines. Id. Thus, the cell functions more efficiently when there is compatibility between the DNA of the nucleus and mitochondrial genes of the cell.
Ordinarily, cells contain only one type of mitochondrial DNA. It has been published that following cytoplasmic transfer or transfer of a cell nucleus in animal cells, multiple different types of mitochondrial DNA or mismatching of mitochondrial DNA and DNA of the nucleus can result. See, for example, Spikings, et al. Hum. Rep. Update vol. 12, no. 4, pp. 401-415 (2006), which is incorporated herein by reference.
For example, mitochondrial cristae are the site of the electron transfer chain, the last stage in cellular respiration where oxidative phosphorylation takes place. Id. This aerobic process allows further metabolism of the products of anaerobic glycolysis and the citric acid cycle to produce carbon dioxide and water, with the subsequent release of 32 molecules of ATP. Id. The components of the electron transfer chain are encoded by both chromosomal and mitochondrial DNA (mtDNA), with all components being required for efficient function.
In an embodiment, the eukaryotic cell includes a cybrid formed by the genome of the nucleus from one source (e.g., endogenous) and the mitochondrial genome from another source (e.g., from a maternally genetically related cell). For example, Rho-zero cells (cells devoid of mitochondrial DNA) can be repopulated with exogenous mitochondrial DNA, resulting in transmitochondrial cybrids. Id. Alternatively, cells can be fused or chemically combined, resulting in cybrid or hybrid cells.
It has been published that genome of the nucleus and mitochondrial genomes interact and communicate in eukaryotic cells. See, for example, Poyton and McEwen, Ann. Rev. Biochem.; Abstract; vol. 65, pp. 563-607 (1996), which is incorporated herein by reference. For example, the genome of the nucleus encodes essential subunit polypeptides utilized in mitochondrial proteins, and is important for several reasons, including the regulation of oxidative energy production. Secondly, they collaborate in the synthesis and assembly of the proteins, which requires the bidirectional flow of information between the nucleus and the mitochondria. Id. In other published examples, the genome of the nucleus encodes proteins that account for about 90% of the protein mass of the mitochondria, including in all four mitochondrial compartments (inner and outer mitochondrial membranes, matrix, and intermembrane space). Id. By contrast, the mitochondrial genome specifies only a few proteins, which reside mainly in the inner mitochondrial membrane. Id. The mitochondrial genome also encodes RNA molecules that co-assemble with proteins encoded in the nucleus. Id.
It has been published that mitochondrial gene products are components of multimeric protein complexes that contain nucleus-encoded components as well. Id. For example, components common to all eukaryotic cells that utilize components encoded by both DNA of the nucleus, as well as mitochondrial DNA include coenzyme Q cytochrome c reductase, cytochrome c oxidase, F1F0 ATPase, and the mitochondrial ribosome. Id. In some eukaryotic cells, NADH dehydrogenase, small and large ribosomal subunits, RNase-P, and RNA splicing enzymes include chimeric components, as well. Id.
With regard to regulation of biosynthesis of mitochondrial proteins, trans-acting genes of the nucleus serve to modulate either the level of expression of mitochondrial genes or in the assembly of respiratory proteins. Id. In certain instances, trans-acting genes of the nucleus serve to modulate either the level of expression of the mitochondrial genome as a whole, or the expression of individual genes on the mitochondrial genome. Id. Furthermore, communication from the genome of the nucleus to the mitochondria involves proteins that are translated in the cytosol and imported into the mitochondria. Id. Communication from the mitochondria to the nucleus likely involves metabolic signals and one or more signal transduction pathways that function across the inner mitochondrial membrane. Id.
It has also been published that mitochondrial gene expression involves interactions between nucleus-coded gene products and the mitochondrial genome or its gene products at several junctions. For example, transcription of mitochondrial gene expression requires interaction with nucleus-coded gene products, RNA processing, and translation utilize various nucleus-coded gene products. Id.
In another example, the proteins encoded by nucleus genes are translated on cytosolic ribosomes (or ribosomes bound to the outer mitochondrial membrane), and are imported by the mitochondria posttranslationally, whereas proteins encoded by mitochondrial genes are translated on endogenous mitochondrial ribosomes that are bound to the matrix side of the inner membrane, and are inserted into it cotranslationally. Id.
It has been published that the genome of the nucleus exerts influence over mitochondrial gene expression as well as the import, export, and assembly pathways required for biogenesis of functional mitochondria. Id.
Thus, supplementation or complementation by mitochondrial replacement, mitochondrial DNA replacement, cell nucleus replacement, or nucleocytoplasmic replacement provides a basis for therapy for cells whose respiration ability is compromised (e.g., due to aging or disease). In certain instances, at least one of mitochondria, mitochondrial DNA, cell nucleus, or nucleocytoplasm is provided to a eukaryotic cell from a maternally genetically related cell. In some cases, the mitochondria, mitochondrial DNA, cell nucleus, or nucleocytoplasm is provided by way of a carrier (e.g., platelet, lipid, polymeric vehicle, etc.).

PROPHETIC EXAMPLES
Example 1
Modification of Mesenchymal Stem Cells with Maternally Genetically Related Mitochondria
A method is described for modifying mesenchymal stem cells with mitochondria from maternally genetically related donor cells prior to autologous transplantation of the stem cells into a subject with amyotrophic lateral sclerosis (ALS). Autologous mesenchymal stem cell transplantation into the spinal cord is being used as a treatment option to attenuate neurodegeneration in individuals with ALS (Mazzini, et al. Exp. Neurology; Abstract; 223:229-237 (2010), which is incorporated herein by reference). Impaired mitochondrial function is a potential causal factor in neuronal dysfunction and degeneration in adult neurodegenerative diseases and is exemplified by reduced mitochondrial gene copy numbers and increased mitochondrial DNA gene deletions in surviving spinal neurons of individuals with ALS (Keeney & Bennett, Mol. Neurodegener. 5:21 (2010), which is incorporated herein by reference). Modifying mesenchymal stem cells with mitochondria from healthy maternally genetically related cells prior to autologous transplantation provides a means for improving mitochondrial function.
Platelets are used as a minimally invasive source of donor mitochondria. In addition, platelets lack DNA of the nucleus and are capable of transferring mitochondria to target cells through cellular fusion (Bacman & Moraes Methods Cell Biol. 80:503-524 (2007), which is incorporated herein by reference). Blood is drawn from a maternally genetically related subject into sterile acid citrate dextrose anticoagulant and centrifuged twice at 200×g for 15 min to pellet red and white blood cells; the resultant platelet-rich plasma is used as the source of platelets. Platelets are isolated by centrifugation of the platelet-rich plasma at 1,400×g for 10 min, and washed twice in washing solution 1 (12.72 mM sodium citrate, 2.99 mM glucose, 9.41 mM NaCl, 0.55 mM EDTA), and washed once in washing solution 2 (1 mM Tris-HCl, 2.99 mM glucose, 15.38 mM NaCl, 0.55 mM EDTA, pH 7.4).
Mitochondria are isolated from the platelets by cell lysis, followed by differential centrifugation (Silvagno, et al. PLoS ONE 5(1):e8670 (2010), which is incorporated herein by reference). Briefly, the platelets are resuspended in a hypotonic lysis buffer (10 mM Tris-HCl, pH 7.4 and 1% protease inhibitor solution) and incubated on ice for 30 minutes. The platelets are lysed by five passages through an insulin syringe needle to generate a total cell extract. The total cell extract is layered on a linear 30-50% sucrose gradient and centrifuged at 134,000×g for 120 minutes in a Beckman SW40 Ti rotor. The resulting particulate bands are diluted in 0.29 M sucrose and pelleted by centrifugation at 100,000×g for 60 minutes.
Alternatively, mitochondria are isolated from lysed platelets using a commercially available mitochondria isolation kit (e.g. Mitochondria Isolation Kit for Cultured Cells, MitoSciences, Eugene, Oreg.). The donor mitochondria isolated from the maternally genetically related cells are analyzed for presence or absence of specific mitochondrial properties prior to insertion of the donor mitochondria into mesenchymal stem cells. Mitochondrial DNA in intact mitochondria can be screened for mutations using specific peptide nucleic acid (PNA) oligomers conjugated to a membrane permeable reagent such as, for example, triphenylphosphonium (see, e.g., Muratovska, et al. Nucleic Acids Res. 29:1852-1863 (2001), which is incorporated herein by reference). A PNA oligomer is designed with a DNA sequence complimentary to a specific mitochondrial sequence, either normal or mutated, and used to assess whether a specific mitochondria contains DNA with that specific sequence.
For this analysis, PNA oligomers are conjugated to triphenylphosphonium by pretreating the PNA with 10 mM HEPES, 1 mM EDTA, and 250 nM 2-mercaptoethanol for 1 hour at 40° C. followed by incubation with iodobutyltriphenylphosphonium in HEPES/EDTA/ethanol for an additional 4 hours. The conjugated PNA is purified using reverse phase HPLC. The PNA is further conjugated to a fluorescent dye, such as FITC, TRITC, and/or BODIPY® derivatives, and/or quantum dots (see, e.g., Dahan Histochem. Cell Biol.; Abstract; 125:451-456 (2006), which is incorporated herein by reference). Relative binding of the fluorescent PNA to the complementary site within the mitochondrial DNA is assessed using either fluorescence microscopy, or fluorescence activated cell sorting. Additional PNA probes are used as negative and positive controls of DNA binding to ensure that the assay system is working. The analysis of donor mitochondria can be compared with that of the recipient mitochondria and/or published information regarding mitochondrial DNA to ensure that the donor mitochondria are healthy.
Autologous mesenchymal stem cells are isolated from the bone marrow of the ALS patient. Bone marrow is collected by aseptic aspiration from the posterior iliac crest using standard procedures. Ex vivo expansion of mesenchymal stem cells is carried out essentially as described by Pittenger, et al. Science, Abstract; 284:143-147 (1999), which is incorporated herein by reference). Briefly, the bone marrow is diluted in four volumes of Minimum Essential Medium Alpha Medium containing 10% fetal bovine serum and centrifuged at 900×g for 15 minutes. The cells are washed in phosphate-buffered saline and plated into an expansion medium containing Dulbecco's Minimum Essential Medium supplemented with 40% MCDB-201, 10% fetal bovine serum, insulin-transferrin-sodium selenite supplement, linoleic acid-bovine serum albumin, 10−8 M dexamethasone, 10−4 M ascorbic acid 2-phosphate, 50 U/ml penicillin/streptomycin, 10 ng/ml human platelet-derived growth factor-BB, and 10 ng/ml human epithelial growth factor. The cells are expanded over several passages prior to transplantation.
Donor mitochondria isolated from the maternally genetically related cells are inserted into cells with existing endogenous mitochondrial DNA, creating a heteroplasmic state. Alternatively, donor mitochondria are inserted into cells lacking endogenous mitochondrial DNA. Cells lacking mitochondrial DNA, termed ρ0 cells, are generated by sustained treatment of cells with a toxin, e.g., ethidium bromide, at a concentration that blocks mitochondrial DNA replication with only minimal effect on DNA of the nucleus (see, e.g., U.S. Pat. No. 5,888,498; Yoon & Koob, Nucleic Acids Res. 31:1407-1415 (2003), which are incorporated herein by reference). Briefly, the mesenchymal stem cells isolated from a patient with ALS are exposed to 5 μg/ml ethidium bromide for 4 weeks in high-glucose medium supplemented with 50 μg/ml uridine and 0.1 mg/ml sodium pyruvate. At the end of 4 weeks, clonal ρ0 cells are isolated by clonal dilution of the ethidium bromide treated cells. PCR with mitochondrial DNA specific primers as well as enzyme assays for cyanide-inhibitable oxygen utilization and complex I or cytochrome c oxidase activity are used to verify the ρ0 state of a clonal population. ρ0 cells can also be generated using other mitochondrial toxins including ditercalinium, rhodamine 6G, dideoxycytidine, streptozotocin (Inoue et al. J. Biol. Chem. 272:15510-15515 (1997); Bacman & Moraes, Methods Cell Biol. 80:503-524 (2007), which are incorporated herein by reference).
The donor mitochondria from the maternally genetically related cells are transferred into the mesenchymal stem cells using cellular fusion in which a cell containing mitochondrial DNA, e.g., a donor platelet, is fused with a cell lacking mitochondrial DNA, e.g., ρ0 mesenchymal stem cells (see, e.g. Bacman & Moraes, Methods Cell Biol. 80:503-524 (2007); Kagawa & Hayashi Gene Ther. 4:6-10 (1997); Pye et al. Nucleic Acids Res. 34:e95 (2006) which are incorporated herein by reference). Fusion is carried out by incubating the two cell populations in the presence of polyethylene glycol (PEG). The ρ0 mesenchymal stem cells are combined with the donor platelets for several hours in growth medium, allowing cell-cell contacts to be made. The medium is completely removed, and PEG 1450 is added to the cells for a brief 30 to 60 second period at which time the PEG is removed and the cells washed. The cells are cultured under selection conditions such that only the fused cells survive.
The modified mesenchymal stem cells are suspended in 1-2 ml of autologous cerebrospinal fluid and injected at multiple sites using a micrometric pump injector into the anterior horns of spinal cord of the ALS patient.
Example 2
Modification of Myoblast Cells with Maternally Genetically Related Mitochondrial DNA
A method is described for modifying myoblast cells with mitochondria from maternally genetically related donor cells prior to autologous transplantation of the myoblast cells into a subject with heart failure. Autologous myoblast cell transplantation into cardiac tissue has been tested as a treatment option for individuals with congestive heart failure and myocardial infarction, as a means for replacing irreversibly damaged cardiomyocytes (see, e.g., Opie and Dib, Nat. Clin. Pract. Cardiovasc. Med. 3 Suppl 1:S42-5 (2006), which is incorporated herein by reference). Impaired mitochondrial function associated with aging is a potential causal factor in the decline in cardiac muscle function (see, e.g., Marin-Garcia, et al. Cardiovasc. Drugs Ther.; Abstract; 20:477-491 (2006), which is incorporated herein by reference). Modifying myoblast cells with mitochondria from healthy maternally genetically related cells prior to autologous transplantation provides a means for improving mitochondrial function.
Lymphocytes are used as a minimally invasive source of donor mitochondria (Choo-Kang et al. Diabetes 51:2317-2320 (2002), which is incorporated herein by reference). Blood is drawn from a maternally genetically related subject using standard procedures. Ideally the donor is younger than the intended recipient. Lymphocytes are isolated from the blood by centrifugation through Ficoll-Hypaque Plus (Amersham Biosciences, Piscataway, N.J.) and incubated for 3 hours at 37° C. in RPMI 1640 medium supplemented with 10% fetal bovine serum (FBS), 50 units/ml penicillin and 50 mg/ml streptomycin. After 3 hours, the non-adherent lymphocytes are removed and further cultured in fresh medium for an additional 48 hours.
Mitochondria are isolated from the lymphocytes by cell lysis, followed by differential centrifugation (Carpentieri & Sordahl, Cancer Res. 40:221-224 (1980), which is incorporated herein by reference). Briefly, the lymphocytes are lysed in 0.25 M sucrose, 5 mM Tri-HCl, 5 mM EGTA, and 0.5% bovine serum albumin using a tight fitting Teflon® pestle attached to a motor rotating at approximately 6000 rpm, a tissue homogenizer (e.g. Tekmar Tissumizer, Tekmar Co. Cincinnati Ohio), or a Dounce homogenizer. The homogenate is centrifuged at 480×g for 10 minutes to remove nuclei and heavier cellular debris. The supernatant is then centrifuged at 10,000×g for 10 minutes to generate a mitochondrial pellet. Alternatively, mitochondria are isolated from lymphocytes using a commercially available mitochondria isolation kit (e.g. Mitochondria Isolation Kit for Cultured Cells, MitoSciences, Eugene, Oreg.).
To isolate mitochondrial DNA, the isolated mitochondria derived from the lymphocytes of a maternally genetically related donor are incubated in 4000 Kunitz units of DNase I at 37° C. for 1 hour to eliminate any residual DNA of the nucleus. The treated mitochondria are subsequently washed through a series of sucrose gradients to remove the DNase I activity. Following DNase I treatment, the mitochondrial DNA is extracted from the mitochondria by digesting the mitochondrial membrane for 3 hours at 50° C. with 10 mg/ml proteinase K in 100 mM NaCl, 10 mM EDTA, 50 mM Tris-HCl, pH 7.4 and 1% SDS. The mitochondrial DNA is further extracted with phenol and chloroform and precipitated with ethanol.
The mitochondrial DNA isolated from the lymphocytes of a maternally genetically related donor is screened for “normalcy” using complete sequence analysis of the mitochondrial genome (see, e.g., Choo-Kang et al. Diabetes 51:2317-2320 (2002), which is incorporated herein by reference). Briefly, 28 to 30 overlapping primers evenly spaced along the mitochondrial DNA template are used for polymerase chain reaction (PCR) amplification across the entire 16-17 kilobase mitochondrial DNA genome. The overlapping PCR fragments are sequenced using an ABI Prism 377 DNA Sequencer (from Applied Biosystems, Foster City, Calif.). The resulting sequence is compared pair-wise using the BLAST2 sequence alignment tool and reference or wild-type sequence information contained in the National Center for Biotechnology Information (NCBI) databases and/or the MITOMAP database (see e.g. Altschul, et al. J. Mol. Biol. 215:403-410 (1990); Ruiz-Pesini et al. Nucleic Acids Res. 35:D823-D828 (2007), each of which is incorporated herein by reference).
The complete mitochondrial DNA sequences of a number of mammalian species including human, mouse, rat, dog, cat, cow, sheep and horse are available in the NCBI databases. In addition, specific information regarding polymorphisms and mutations of the human mitochondrial genome can be accessed through the MITOMAP database.
Myoblast cells for autologous transplantation are derived from skeletal muscle biopsy samples taken from the subject with heart failure (see, e.g. Dib, et al. Circulation 112:1748-1755 (2005), which is incorporated herein by reference). The skeletal muscle biopsy sample is trimmed of connective tissue, minced into a slurry, and digested at 37° C. with trypsin/EDTA (0.5 mg/ml trypsin, 0.53 mmol/L EDTA) and collagenase (0.5 mg/ml) to release the myoblast cells. The myoblast cells are plated and grown in myoblast basal growth medium (SkBM Basal Medium, Lonza, Basel Switzerland), containing 15% fetal bovine serum, recombinant human epidermal growth factor (10 ng/ml), and dexamethasone (3.9 ug/ml). The myoblast cells are expanded for 11 to 13 doublings prior to harvest.
Mitochondrial DNA is introduced into the myoblast cells using protein-mediated transfection (see, e.g., Keeney, et al. Hum. Gene Ther., Abstract; 20:897-907 (2009), which is incorporated herein by reference). Briefly, the mitochondrial DNA isolated from the mitochondria of the maternally genetically related cells is combined with recombinant fusion protein complex containing mitochondrial transcription factor A (TFAM) engineered to include an N-terminal, 11-arginine protein transduction domain followed by a mitochondrial localization signal (MTD). The recombinant MDT-TFAM protein complex binds the donor mitochondrial DNA and is used to selectively import the DNA into the mitochondria of the myoblast cells. MDT-TFAM is combined in 2 to 3 fold excess with the donor mitochondrial DNA in a buffer designed to stabilize long DNA templates such as, for example, 85 mM potassium acetate, 25 mM Tricine (pH 8.7), 8% glycerol, 1% DMS) and 1.1 mM magnesium acetate and incubated for 30 minutes at 37° C. The MDT-TFAM-mitochondrial DNA solution is diluted in the myoblast basal growth medium described above and applied to the myoblast cells for 4 hours at 37° C.
Alternatively, the donor mitochondrial DNA can be introduced into the mitochondria of the myoblast cells using a mitochondrial leader sequence peptide that is recognized by the mitochondrial protein import machinery. For example, the mitochondrial DNA can be linked to the pre-sequence peptide of the nucleus encoded cytochrome c oxidase (COX) subunit VIII, (U.S. Patent Application 2004/0192627 A1, which is incorporated herein by reference). The mitochondrial DNA is conjugated to the pre-sequence peptide using pGeneGRIPTM-PNA dependent chemistry (from, e.g., Genlantis, San Diego, Calif.). The PNA is designed to hybridize with a portion of the mitochondrial DNA as well as the pre-sequence peptide of COX subunit VIII. In this manner, the pre-sequence peptide is linked to the mitochondrial DNA and can facilitate import of the DNA into the mitochondria.
The mitochondrial DNA is imported into myoblast cells that have been pretreated with a mitochondrial toxin as described in Example 1 to generate ρ0 myoblast cells. Alternatively, the mitochondrial DNA is imported into untreated myoblast cells to dilute the endogenous dysfunctional mitochondrial DNA with healthy mitochondrial DNA.
For transplantation, the autologous myoblast cells modified with mitochondrial DNA from the maternally genetically related cells are injected into the infarcted area of the recipient's heart. One to four, doses of 1 to 30×107 cells are injected in 3 to 30 injections of 0.1 ml each in a non-overlapping pattern in the area of infarction on the epicardial surface. Transplantation of autologous myoblast cells modified with donor mitochondrial DNA can be performed during concurrent coronary artery bypass grafting (CABG) or left ventricular assist device (LVAD) implantation.

Treatment of Cytoplasmic Male Sterility in Zea mays Using Mitochondria from Maternally Genetically Related Cells
A method is described for treating cytoplasmic male sterility in Zea mays (maize) using mitochondria isolated from maternally genetically related cells. Cytoplasmic male sterility is characterized by the inability of an otherwise normal plant to develop functional anthers, pollen, or male gametes, resulting in total or partial male sterility. Cytoplasmic male sterility is associated with a variety of mitochondrial DNA arrangements arising from low frequency, illegitimate recombination, or nonhomologous end joining activity within the mitochondrial genome, resulting in aberrant open reading frames comprised of chimeric sequences. (See, e.g., Mackenzie & McIntosh, Plant Cell, 11:571-585, (1999); Kubo & Newton, Mitochondrion; Abstract; 8:5-14 (2008), each of which is incorporated herein by reference). In order to restore male fertility in a deficient genotype of Zea mays, mitochondria from maternally genetically related cells isolated from a genotype of Zea mays exhibiting normal fertility are introduced into developing Zea mays embryos.
Mitochondria for microinjection into Zea mays embryos are isolated from seedlings of a maternally genetically related genotype. Briefly, one hundred grams of seedlings are placed in a grinding buffer (e.g., 0.35 M sorbitol, 50 mM Tris pH 7.6, 5 mM EDTA, 0.2% bovine serum albumin, 1.0% polyvinylpropyline, 0.025% spermine, 0.025% spermidine, 0.125% betamercaptoethanol) and homogenized in a blender on high for 3×15 seconds. Homogenate is filtered through cheesecloth and centrifuged at 3,000×g for 10 minutes. The resulting supernatant is centrifuged at 16,000×g for 30 minutes. The pellet is gently resuspended in a wash buffer (e.g., 0.35 M sorbitol, 50 mM Tris pH 7.6, 0.1% bovine serum albumin) and recentrifuged at 16,000×g. The pellet is resuspended in wash buffer with the addition of 25 mM MgCl2 and treated with 100 ug/ml DNase I for 30-60 minutes on ice to remove contaminating DNA of the nucleus. The suspension is centrifuged at 2,000×g and the resulting supernatant centrifuged at 16,000×g. The pellet is resuspended in wash buffer and overlayed onto a Percoll gradient and centrifuged at 12,000×g for 1 hour. The mitochondria are collected at the 23:40 interface, washed with buffer, and centrifuged at 20,000×g for 30 minutes. The pellet containing purified mitochondria is resuspended in wash buffer and either used immediately to extract DNA or RNA or it is frozen at −20° C. in a 1:1 mixture of wash buffer and 50% glycerol.
The mitochondrial DNA isolated from the maternally genetically related cells is isolated using a cesium gradient. Briefly, the mitochondria are resuspended in a lysis buffer (e.g., 1.0% Sarkosyl, 50 mM Tris pH 8.0, 25 mM EDTA, 10 mg/ml proteinase K) and digested at 37° C. for 1 hour. Cesium chloride (100% w/v) is dissolved into the digest and ethidium bromide added to 0.2 mg/ml. The solution is centrifuged at 55,000 rpm for 20 hours. An ethidium bromide stained band containing the mitochondrial DNA is removed and the DNA precipitated with ethanol.
The mitochondrial DNA from the maternally genetically related cells is assessed for “normalcy” using a shotgun sequencing approach (see, e.g., Allen, et al., Genetics 177:1173-1192 (2007), which is incorporated herein by reference). The purified mitochondrial DNA is fragmented, ligated into a plasmid cloning vector and transfected into an Escherichia coli host strain (e.g., DH10B-T1) to generate a sequencing library. The fragments of mitochondrial DNA are isolated and sequenced using an ABI Prism 377 DNA Sequencer (from Applied Biosystems, Foster City, Calif.). Sequence associated with the plasmid cloning vector is subtracted and over-lapping mitochondrial DNA sequences are pieced together to generate a complete mitochondrial genome sequence. The resulting mitochondrial genomic sequence from the maternally genetically related genotype is compared with that of other fertile strains of Zea mays (e.g., NA and NB) using a sequence alignment tool (e.g., Multalin; Corpet, Nucl. Acids Res., 16:10881-10890, 1988, which is incorporated herein by reference).
Fertilized embryos for use in microinjection are isolated from Zea mays plants grown to maturity. Methods to isolate plant embryos are known in the art (see e.g., U.S. Pat. No. 6,300,543, which is incorporated herein by reference). Maize plants with silks 6-10 cm in length are pollinated by hand and the plants are placed in a growth chamber for at least 16 hours to allow fertilization to occur. Ovaries are isolated by removing husks and silks from the cobs and cutting the cobs transversely in 3 cm segments. The segments are sterilized for 10 minutes in 70% ethanol and rinsed in deionized water. Ovaries are then removed and mounted for sectioning.
Specimen blocks for use in the microtome are surface sterilized in 70% ethanol for 10 minutes, and the alcohol is evaporated in a laminar flow hood. A thin layer of adhesive, “Quik Set 404” (available from Locktite Corp., Newington, Conn.), is used to immobilize the ovaries with their adiaxial surface up. The blocks with attached ovaries are placed in a Vibratome (available from Technical Products International., St. Louis, Mo.), and sectioned at a thickness of 200-400 μm. Microscopic inspection of the sections is used to identify 250 μm to 300 μm slices containing embryo sacs. Sections containing embryo sacs are collected and placed on a modified Murashige-Skoggs medium with 0.4 mg/L L-asparagine, 0.1 mg/L 6-benzylaminopurine (BAP) and 15% sucrose, pH 5.8. Media and culture conditions for plant embryos are known in the art (see e.g., Hecht et al., Physiol. Plant 127: 803-816 (2001), which is incorporated herein by reference).
Zygotes contained in intact embryo sacs are microinjected with the mitochondrial isolated from the maternally genetically related strain. For microinjection, one to six picoliters of solution containing 200-2000 mitochondria is microinjected into single oocytes using a Stemi SV11 Stereomicroscope (available from Carl Zeiss Microimaging, Inc., Thornwood, N.Y.) equipped with Narishige micromanipulators and a PL-100 pico-injector (micromanipulators and injector are available from Tritech Research, Los Angeles, Calif.). Embryo sacs are cultured at 25°C. in the dark on modified Murashige-Skoggs medium with 0.4 mg/L L-asparagine, 0.1 mg/L 6-benzylaminopurine (BAP) and 15% sucrose, pH 5.8.
In order to grow plants from the microinjected zygotes, the embryo sacs are transferred to media lacking BAP, and cultured in vitro. Embryo sacs are cultured in Murashige-Skoggs medium with 0.4 mg/L L-asparagine and 10% sucrose, pH 5.8 for 5 days at 25° C. in the dark, and then transferred to the same medium containing only 3% sucrose for another 5 days. When young shoots are approximately 1.5 cm long, they are exposed to light. After the embryos have grown into plantlets in vitro, they are planted in sterilized soil or vermiculite and grown to maturity in a greenhouse. The resulting plants are assessed for the presence of anthers, pollen and/or male gametes as indicators of recovery of male fertility. Various methods for determining viability of pollen and/or male gametes have been described (see, e.g., Dumas & Mogensen, Plant Cell, 5:1337-1348 (1993) which is incorporated herein by reference).
