Isolated complex endophyte compositions and methods for improved plant traits
This invention relates to methods and materials for providing a benefit to a plant by associating the plant with a complex endophyte comprising a host fungus further comprising a component bacterium, including benefits to a plant derived from a seed or other plant element treated with a complex endophyte. For example, this invention provides purified complex endophytes, purified complex endophyte components such as bacteria or fungi, synthetic combinations comprising said complex endophytes and/or components, and methods of making and using the same.
1. A synthetic composition, comprising a plant element heterologously associated with an endophytic component, wherein said endophyte comprises a nucleic acid sequence at least 97% identical to SEQ ID NO: 333, and wherein said endophyte is capable of providing a trait of agronomic importance to said plant element.
2. The synthetic composition of claim 1 , wherein said trait of agronomic importance is selected from the group consisting of: germination rate, emergence rate, shoot biomass, seedling root length, seedling shoot length, seedling mass, root surface area, enhanced nutrient use efficiency, and yield.
3. The synthetic composition of claim 2 , wherein the trait of agronomic importance is improved under normal watering conditions.
4. The synthetic composition of claim 2 , wherein the trait of agronomic importance is improved under normal watering conditions.
5. The synthetic composition of claim 1 , wherein said synthetic composition further comprises an agronomic formulation that further comprises one or more of the following: a stabilizer, or a preservative, or a carrier, or a surfactant, or an anticomplex agent, fungicide, nematicide, bactericide, insecticide, and herbicide, or any combination thereof.
6. The synthetic composition of claim 1 , wherein said endophyte is present in an amount of at least 10 2 CFU per plant element.
7. The synthetic composition of claim 1 , wherein said plant element is selected from the group consisting of: whole plant, seedling, meristematic tissue, ground tissue, vascular tissue, dermal tissue, seed, leaf, root, shoot, stem, flower, fruit, stolon, bulb, tuber, corm, keikis, and bud.
8. The synthetic composition of claim 1 , wherein said plant element is from a plant selected from the group consisting of: wheat, soybean, maize, cotton, canola, barley, sorghum, millet, rice, rapeseed, alfalfa, tomato, sugarbeet, sorghum, almond, walnut, apple, peanut, strawberry, lettuce, orange, potato, banana, sugarcane, potato, cassava, mango, guava, palm, onions, olives, peppers, tea, yams, cacao, sunflower, asparagus, carrot, coconut, lemon, lime, barley, watermelon, cabbage, cucumber, grape, and turfgrass.
9. A method of inoculating a plant with a synthetic composition, comprising contacting a plant element of said plant with a formulation comprising a heterologous endophyte, wherein said endophyte comprises a nucleic acid sequence at least 97% identical to SEQ ID NO: 333, and wherein the endophyte is heterologously disposed to the plant element in an amount effective to improve a trait of agronomic compared to a reference plantgrown under the same conditions.
10. The method of claim 9 , wherein said trait of agronomic importance is selected from the group consisting of: germination rate, emergence rate, shoot biomass, seedling root length, seedling shoot length, seedling mass, root surface area, enhanced nutrient use efficiency, and yield.
11. The method of claim 10 , wherein the trait of agronomic importance is improved under normal watering conditions.
12. The method of claim 10 , wherein the trait of agronomic importance is improved under conditions of water limitation.
13. The method of claim 9 , wherein said synthetic composition further comprises an agronomic formulation that further comprises one or more of the following: a stabilizer, or a preservative, or a carrier, or a surfactant, or an anticomplex agent, fungicide, nematicide, bactericide, insecticide, and herbicide, or any combination thereof.
14. The method of claim 9 , wherein said endophyte is present in an amount of at least 10 2 CFU per plant element.
15. The method of claim 9 , wherein said plant element is selected from the group consisting of: whole plant, seedling, meristematic tissue, ground tissue, vascular tissue, dermal tissue, seed, leaf, root, shoot, stem, flower, fruit, stolon, bulb, tuber, corm, keikis, and bud.
16. The method of claim 9 , wherein said plant element is from a plant selected from the group consisting of: wheat, soybean, maize, cotton, canola, barley, sorghum, millet, rice, rapeseed, alfalfa, tomato, sugarbeet, sorghum, almond, walnut, apple, peanut, strawberry, lettuce, orange, potato, banana, sugarcane, potato, cassava, mango, guava, palm, onions, olives, peppers, tea, yams, cacao, sunflower, asparagus, carrot, coconut, lemon, lime, barley, watermelon, cabbage, cucumber, grape, and turfgrass.
