Cultural practices, such as tillage, often have widespread impacts on phytobiomes. No-till has been increasingly adopted by wheat growers in the dryland cropping areas of inland Pacific Northwest United States to reduce soil erosion and decrease fuel labor inputs, yet there are limited data how conversion no-till plant-associated bacteria this highly productive system. To address knowledge gap, we evaluated bacterial communities bulk rhizosphere two locations (Idaho Washington) for 2 years, comparing long-term plots adjacent under conventional tillage. In study, members phylum Proteobacteria were relatively more abundant soil, while Acidobacteria Gemmatimonadetes than rhizosphere. Bacteroidetes frequent conservation general, families affected position sample (rhizosphere versus soil) tillage practices. Families generally regarded copiotrophic (Oxalobacteriaceae, Pseudomonadaceae, Cytophagaceae) both years. On contrary, oligotrophic Gaiellaceae those within varied between These results suggest that influenced plant proximity but specific differences not consistent may vary among
