Compositions and methods for improving tomato production
The present invention provides both compositions comprising Methylobacterium and compositions comprising Methylobacterium that are depleted of substances that promote growth of resident microorganisms on a tomato plant or seed. Also provided are methods for improving tomato production, methods of making the compositions, and methods of treating a tomato plant, plant part, or seed with the compositions comprising Methylobacterium.
1. A method for improving tomato production, said method comprising: (i) treating a tomato plant, a part thereof, or a tomato seed by spraying, coating, partially coating, immersing, and/or imbibing the plant, plant part or seed with a composition comprising the Methylobacterium strain NLS0017 which has been deposited under NRRL B-50931 or the Methylobacterium strain NLS0066 which has been deposited under NRRL B-50940, wherein the composition comprising the Methylobacterium strain NLS0017 or NLS0066 has a Methylobacterium titer of at least 1×10 6 colony forming units per gram (CFU/gm) or at least 1×10 6 CFU per milliliter (CFU/mL); and (ii) growing the treated tomato plant, plant part, or the treated seed to produce a plant;
wherein said tomato plant or tomato plant grown from said seed exhibits a trait improvement selected from the group consisting of an increased rate of root growth, leaf growth, seedling growth, seed production, fruit production, scion production, rootstock production, and increased total biomass when compared to an untreated control tomato plant or a control tomato plant grown from an untreated seed, thereby improving tomato production.
2. The method of claim 1 , wherein said composition comprises Methylobacterium at a titer of about 1×10 6 CFU/gm to about 1×10 14 CFU/gm for a solid composition or at a titer of about 1×10 6 CFU/mL to about 1×10 11 CFU/mL for a liquid composition.
3. The method of claim 1 , wherein said composition coats or partially coats said tomato plant or a part thereof, or said seed.
4. The method of claim 1 , wherein the method further comprises: (iii) harvesting seedlings, rootstock, scions, fruit, or seed from said tomato plant or tomato plant grown from said seed.
5. The method of claim 1 , wherein the composition comprises an agriculturally acceptable adjuvant and/or excipient.
6. The method of claim 1 , wherein said composition is applied to said tomato plant, part thereof, or seed in a hydroponic solution.
7. The method of claim 1 , wherein said composition is depleted of substances that promote growth of resident microorganisms on said plant or seed.
8. A tomato plant part or tomato seed that is coated or partially coated with a composition comprising the Methylobacterium strain NLS0017 which has been deposited under NRRL B-50931 or the Methylobacterium strain NLS0066 which has been deposited under NRRL B-50940, wherein the composition is a solid composition comprising the Methylobacterium at a titer of at least 1×10 6 CFU/gm.
9. A tomato plant part or tomato seed that is coated or partially coated with a composition comprising the Methylobacterium strain NLS0017 which has been deposited under NRRL B-50931 or the Methylobacterium strain NLS0066 which has been deposited under NRRL B-50940, wherein the composition is a liquid composition comprising the Methylobacterium at a titer of at least 1×10 6 CFU/mL.
