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: Contrary to what has been described for other bacteria, the P. aeruginosa core genome is constituted by a high proportion of genes and that its pan-genome is thus relatively small, considering the high degree of genomic conservation between isolates of P.aeruginose from diverse environments, including human tissues.

TL;DR: In this article, the authors characterized the dsDNA viral diversity in biochar-amended agricultural soils at the preplanting and harvesting stages of a tomato growing season via paired total metagenomes and viromes.
