Abstract

Materials and methods for improving plant traits and for providing plant benefits are provided. In some embodiments, the materials, and methods employing the same, can comprise endophytes.

First claim

1 .- 146 . (canceled)

147 . A treatment formulation and a purified microbial population, wherein the purified microbial population comprises a first endophyte comprising a nucleic acid sequence having 97% identity or greater to SEQ ID NOs: 3576 or 3623, and wherein the treatment formulation comprises a mineral carrier.

148 . The treatment formulation of claim 147 , further comprising a second endophyte, wherein the second endophyte is of the genus Kosakonia.

149 . The treatment formulation of claim 1 , wherein the second endophyte comprises a nucleic acid sequence comprising SEQ ID NO: 3115.

150 . The treatment formulation of claim 147 , further comprising at least one member selected from the group consisting of an agriculturally compatible carrier, a tackifier, a microbial stabilizer, a fungicide, an antibacterial agent, an herbicide, a nematicide, an insecticide, a plant growth regulator, a rodenticide, and a nutrient.

151 . A synthetic combination comprising a plurality of plant elements and a purified microbial population comprises a first endophyte comprising a nucleic acid sequence having 97% identity or greater to SEQ ID NOs: 3576 or 3623.

152 . The synthetic combination of claim 151 , wherein the benefit is selected from the group consisting of increased root biomass, increased root length, increased height, increased shoot length, increased leaf number, increased water use efficiency, increased overall biomass, increase grain yield, increased photosynthesis rate, increased heat tolerance, increased salt tolerance, increased resistance to nematode stress, increased resistance to a fungal pathogen, increased resistance to a bacterial pathogen, increased resistance to a viral pathogen, a detectable modulation in the level of a metabolite, and a detectable modulation in the proteome relative to a reference plant.

153 . The synthetic combination of claim 151 , wherein the first endophyte is present in an amount of at least about 100 CFU or spores per plant element.

154 . The synthetic combination of claim 151 , wherein the plant element is seeds and the first endophyte is associated with the seeds as a coating on the surface of the seeds.

155 . The synthetic combination of claim 151 , wherein the plant element is seedlings and the first endophyte is contacted with the seedlings as a spray applied to one or more leaves and/or one or more roots of the seedlings.

156 . The synthetic combination of claim 151 , wherein the first endophytes are present in an at least 300 CFU, at least 1,000 CFU, at least 3,000 CFU, at least 10,000 CFU, at least 30,000 CFU, at least 100,000 CFU, at least 300,000 CFU, or at least 1,000,000 CFU per seed.

157 . The synthetic combination of claim 151 , wherein the agricultural plant is a dicot selected from the group consisting of soybean, canola, rapeseed, cotton, alfalfa, cassava, potato, tomato, pea, chick pea, lentil, flax, or pepper.

158 . The synthetic combination of claim 151 , wherein the agricultural plant is a monocot selected from the group consisting corn, wheat, barley and rice.

159 . The synthetic combination of claim 151 , further comprising a second endophyte, wherein the second endophyte is of the genus Kosakonia.

160 . The synthetic combination of claim 159 , wherein the second endophyte comprises a nucleic acid sequence comprising SEQ ID NO: 3115.

161 . The synthetic combination of claim 151 , comprising at least one member selected from the group consisting of an agriculturally compatible carrier, a tackifier, a microbial stabilizer, a fungicide, an antibacterial agent, an herbicide, a nematicide, an insecticide, a plant growth regulator, a rodenticide, and a nutrient.
