TL;DR: Dynamic changes observed during microbiome acquisition, as well as steady-state compositions of spatial compartments, support a multistep model for root microbiome assembly from soil wherein the rhizoplane plays a selective gating role.

TL;DR: The results reveal that drought stress, in addition to its well-characterized effects on plant physiology, also results in restructuring of root microbial communities and suggest the possibility that constituents of the altered plant microbiota might contribute to plant survival under extreme environmental conditions.

TL;DR: Dense temporal sampling of 1,510 samples from root spatial compartments is used to characterize the bacterial and archaeal components of the root-associated microbiota of field grown rice over the course of 3 consecutive growing seasons, as well as 2 sites in diverse geographic regions and shows that shifts in the microbiome are correlated with rates of developmental transitions rather than age alone.

TL;DR: In this paper, a detailed temporal characterization of root-associated microbiomes of rice plants during drought stress and recovery was performed, showing that root communities remained compositionally altered after rewatering, with prolonged droughts leading to decreased resilience.

TL;DR: It is shown that continuous monoculture of the major food crop rice under flooded conditions is associated with a pronounced shift in soil bacterial and archaeal microbiota structure towards a more consistent composition, thereby domesticating microbiota of previously uncultivated sites.
