| Summary: | Rhizosphere microbial communities exert critical roles in plant health, nutrient cycling, and the fertility of the soil. Despite this, the origin and acquisition of rhizosphere microbes is not fully understood. In this study, we investigated the diversity and potential origin of the microbial communities on Colobanthus quitensis (Cq) and Deschampsia antarctica(Da). Microbial communities form the rhizoshere of Da exhibited decreased richness and diversity in comparison with Cq and Da.Cq. In contrast, fungal diversity was strongly associated with plant species, where the rhizospehre of Da exhibited greater diversity than that of Cq. We also found that species turnover is mostly determined by environmental and geographic filters, and to a lesser extent, to biotic filters. Morover, our analyses showed that the likely origin of rhizosphere bacteria is local soils that contribute to homogenize rhizosphere community composition among different plant species growing on the same sites. The observed pattern is ... |
