Methods of use of seed-origin endophyte populations
First Claim
1. A method of treating seeds of a cereal agricultural plant, comprising mechanically or manually contacting a plurality of seeds with a composition comprising a purified bacterial population that comprises a seed bacterial endophyte that is capable of producing an auxin or acetoin, and has a 16S nucleic acid sequence that is at least 97% identical to a 16S nucleic acid sequence selected from the group consisting of SEQ ID NO:
- 521, 533, 560, 710, 856, 1447, 530, 536, 588, and 658, and the endophyte is heterologously disposed to the seed in an amount effective to colonize the plant and to increase germination efficiency of the treated seed as compared to a reference seed sowed under the same conditions.

Abstract
This application relates to methods and materials for providing a benefit to a seed or seedling of an agricultural plant (e.g., an agricultural grass plant), or the agricultural plant derived from the seed or seedling. For example, this application provides purified bacterial populations that include novel seed-origin bacterial endophytes, and synthetic combinations of seeds and/or seedlings (e.g., cereal seeds and/or seedlings) with heterologous seed-derived bacterial endophytes.

11. A method of treating seeds of a cereal agricultural plant, comprising mechanically or manually contacting a plurality of seeds with a composition comprising a purified bacterial population that comprises a first bacterial endophyte and a second bacterial endophyte, wherein the first bacterial endophyte and second bacterial endophyte have a 16S nucleic acid sequence that is at least 97% identical to a 16S nucleic acid sequence selected from the group consisting of SEQ ID NO:
- 521, 533, 560, 588, 658 and 856, and is capable of producing an auxin or acetoin, wherein the first bacterial endophyte and second bacterial endophyte have different 16S nucleic acid sequence, wherein the first and second endophytes are heterologously disposed to the seed in an amount effective to colonize the plant and to increase germination efficiency of the treated seed as compared to a reference seed sowed under the same conditions.
