Abstract

Microbial strains, compositions, and methods of use thereof to enhance the growth and/or yield of a plant are provided. Also provided are materials and methods for presenting, inhibiting, or treating the development of plant pathogens or phytopathogenic diseases. The disclosure also provides non-naturally occurring plant and derivatives thereof such as plants artificially infected with a microbial strain of the invention.

First claim

What is claimed is:

1. A coated plant seed having a coating comprising a carrier and an endophyte, wherein the endophyte comprises microbial strain SGI-003-H11, deposited as NRRL B-50483.

2. The coated plant seed of claim 1 , further comprising an agriculturally effective amount of a compound selected from the group consisting of a fertilizer, an acaricide, a bactericide, a fungicide, an insecticide, a microbicide, a nematicide and a pesticide.

3. The coated plant seed of claim 1 , wherein said composition is a seed coating formulation.

4. The coated plant seed of claim 1 , wherein said composition is prepared as a formulation selected from the group consisting of an emulsion, a colloid, a dust, a granule, a pellet, a powder, a spray and a solution.

5. The coated plant seed of claim 1 , wherein said plant seed is a corn plant seed or a wheat plant seed.

6. The plant seed of claim 1 , wherein the microbial strain SGI-003-H11 comprises a nucleotide sequence that exhibits at least 90% identity to SEQ ID NO:1.

7. The plant seed of claim 1 , wherein the microbial strain SGI-003-H11 comprises a nucleotide sequence that exhibits at least 99% identity to SEQ ID NO:1.

8. The plant seed of claim 1 , wherein the microbial strain SGI-003-H11 comprises the nucleotide sequence comprising SEQ ID NO:1.

9. A method for producing the coated plant seed of claim 1 , said method comprising a step of exposing or contacting said plant seed with said microbial strain SGI-003-H11, deposited as NRRL B-50483, wherein the coated plant seed is produced.

10. A method for inhibiting or treating the development of a pathogenic disease of a plant caused by a plant pathogen, said method comprising growing a plant from the coated seed of claim 1 .

11. The method according to claim 10 , wherein said plant pathogen is selected from the group consisting of Colletotrichum, Monographella, Penicillium , and Stagnospora organisms.

12. The method according to claim 10 , wherein said plant pathogen is selected from the group consisting of Colletotrichum graminicola, Monographella nivalis, Penicillium sp., or Stagnospora noduruin.

13. The method according to claim 10 , wherein said microbial strain is additionally applied to soil or a plant or plant part thereof grown from said coated seed.
