Comparative analysis of rhizosphere microbiomes of cultivated and wild rice under contrasting field water regimes.

ABSTRACT: Asian cultivated rice (Oryza sativa L.) is domesticated from the common wild rice (Oryza rufipogon Griff.). However, the increasing water stress caused by climate change in recent years has become a major threat to rice growth and yield. To explore the adaptive changes of rhizosphere microbiomes in annual cultivated and perennial wild rice under different water limitation conditions, we conducted metagenomic sequencing analysis on rice rhizosphere soil samples from natural environments with varying water conditions. In particular, the genus Pseudomonas plays a dominant role in the rhizosphere microbiome of wild rice under non-irrigated condition. For archaea, we found that, compared to non-irrigated condition, submergence condition enriched methanogenic Methanosarci
