Title:	Preventing or delaying chill injury response in plants
Abstract:	Provided are methods and compositions for preventing or delaying a chill injury response of a plant or plant part that exhibits a chill injury response. The methods comprise exposing the plant or plant part to one or more bacteria, one or more enzymes, and/or an enzymatic extract isolated from one or more bacteria. The one or more bacteria, one or more enzymes, and/or the enzymatic extract isolated from one or more bacteria are exposed to the plant or plant part in a quantity sufficient to prevent or delay the chill injury response of the plant or plant part.

Application Number:	14/773,811
Patent Claims:	1. A method for delaying a chill injury response of a plant or plant part that exhibits a chill injury response comprising exposing the plant or plant part to one or more bacteria, wherein the one or more bacteria are exposed to the plant or plant part in a quantity sufficient to prevent or delay the chill injury response of the plant or plant part, where the plant or plant part is stored at a temperature of about 4 to 7.degree. C. prior to, during, or after exposure to the one or more bacteria, and wherein the one or more bacteria are selected from the group consisting of Rhodococcus spp., Brevibacterium ketoglutamicum, Pseudomonas chloraphis, and combinations thereof. 2. The method of claim 1, wherein the plant or plant part is selected from the group consisting of a fruit, a vegetable, and a flower. 3. The method of claim 1, wherein the Rhodococcus spp. includes Rhodococcus rhodochrous DAP96253 strain, Rhodococcus rhodochrous DAP 96622 strain, Rhodococcus erythropolis, or combinations thereof. 4. The method of claim 1, wherein the one or more bacteria are induced to produce one or more enzymes by exposure to an inducing agent selected from the group consisting of urea, methyl carbamate, cobalt, asparagine, asparagine derivatives, glutamine, glutamine derivatives, and combinations thereof. 5. The method of claim 1, wherein the one or more bacteria are stabilized with a stabilizing agent. 6. The method of claim 5, wherein the stabilizing agent is trehalose. 7. The method of claim 1, wherein the one or more bacteria are fixed with glutaraldehyde and cross-linked. 8. The method of claim 7, wherein the glutaraldehyde-fixed bacteria are formulated into a spray. 9. The method of claim 1, wherein the one or more bacteria are provided in liquid form and the liquid is sprayed onto or near the plant or plant part. 10. The method of claim 9, wherein the liquid further comprises a liquid carrier. 11. The method of claim 10, wherein the liquid carrier is selected from the group consisting of an aromatic hydrocarbon, a substituted naphthalene, a phthalic acid ester, an aliphatic hydrocarbon, an alcohol, and a glycol. 12. The method of claim 1, wherein the one or more bacteria are provided in solid form and the solid is dusted onto or near the plant or plant part. 13. The method of claim 12, wherein the solid further comprises a solid carrier. 14. The method of claim 13, wherein the solid carrier is selected from the group consisting of a dust, a wettable powder, a water dispersible granule, and a mineral filler. 15. The method of claim 14, wherein the mineral filler is selected from the group consisting of a calcite, a silica, a talc, a kaolin, a montmorillonite, and an attapulgite. 16. The method of claim 12, wherein the one or more bacteria further comprises a hydrophobic fatty acid polyester coating, wherein the hydrophobic fatty acid polyester coating makes the one or more bacteria water resistant. 17. The method of claim 16, wherein the hydrophobic fatty acid polyester coating is a long chain fatty acid polyester derived from sucrose, sorbitol, sorbinose, glycerol, or raffinose. 18. The method of claim 1, further comprising exposing the plant or plant part to one or more exogenous enzymes, wherein the one or more exogenous enzymes are exposed to the plant or plant part in a quantity sufficient to prevent or delay the chill injury response of the plant or plant part. 19. The method of claim 18, wherein the one or more exogenous enzymes are selected from the group consisting of nitrile hydratase, amidase, asparaginase, ACC deaminase, cyanoalanine synthase-like enzyme, alkane monooxygenase, ammonium monooxygenase, methane monooxygenase, toluene dioxygenase, cyanidase, and combination thereof.
