In the domain Bacteria , one of largest, most diverse and environmentally ubiquitous phylogenetic groups, Candidatus Patescibacteria (also known as candidate phyla radiation/CPR), remains poorly characterized, leaving a major knowledge gap in microbial ecology. We recently discovered novel cross-domain symbiosis between Ca .

The rhizosphere of Phaseolus vulgaris L. cultivars hosts a similar bacterial community in local agricultural soils

This study aimed to investigate the impact of various common beans ( Phaseolus vulgaris L.) cultivars on bacterial communities in rhizosphere under local agricultural conditions. Even though differences cultivation history and physicochemical properties nearby agriculture plots, community bulk soil was quite similar more diverse than that rhizosphere. The closely between Black Bayo bean but differs from Pinto Saltillo collected a different season. A shared group within across specific taxa responding uniquely each cultivar suggests balance responses plant cultivars. Nevertheless, composition substantially influenced by pre-existing community, whose diversity remained consistently studied field These findings provide comprehensive characterization limited range domesticated agronomic soils can be expanded guide appropriate interventions.
