The rhizosphere environment selects a particular microbial community that arises from the one present in bulk soil due to the release of particular compounds in exudates and different opportunities for microbial colonization. During plant-microorganism coevolution, microbial functions supporting plant health and productivity have developed, of which most are described in cultured plant-associated bacteria. This review discusses the state of the art concerning the ecology of the hitherto-uncultured bacteria of the rhizosphere environment, focusing on Acidobacteria, Verrucomicrobia and Planctomycetes. Furthermore, a strategy is proposed to recover bacterial isolates from these taxa from the rhizosphere environment.
根际环境会选择一个特定的微生物群落，该群落源于由于根系分泌物中特定化合物的释放以及微生物定殖的不同机会而存在于大块土壤中的微生物群落。在植物与微生物的共同进化过程中，支持植物健康和生产力的微生物功能得以发展，其中大多数已在培养的植物相关细菌中得到描述。本综述讨论了根际环境中迄今未培养细菌的生态学现状，重点关注酸杆菌门、疣微菌门和浮霉菌门。此外，还提出了一种从根际环境中分离这些类群细菌的策略。
