TL;DR: The pyrosequencing of the bacterial 16S ribosomal RNA gene of more than 600 Arabidopsis thaliana plants is reported to test the hypotheses that the root rhizosphere and endophytic compartment microbiota of plants grown under controlled conditions in natural soils are sufficiently dependent on the host to remain consistent across different soil types and developmental stages.

TL;DR: It is established that biosynthesis of, and signaling dependent on, the foliar defense phytohormone salicylic acid is required to assemble a normal root microbiome, and selection from the available microbial communities to sculpt the root microbiome.

TL;DR: This large-scale field experiment disentangle the effects of genotype, environment, age and year of harvest on bacterial communities associated with leaves and roots of Boechera stricta (Brassicaceae), a perennial wild mustard to demonstrate how genotype-by-environment interactions contribute to the complexity of microbiome assembly in natural environments.

TL;DR: This work sequenced 484 genomes of bacterial isolates from roots of Brassicaceae, poplar, and maize and validated candidates from two sets of plant-associated genes, including one involved in plant colonization and the other serving in microbe–microbe competition between plant and microbe.

TL;DR: Plant genetic effects were significant amid the large effects of plant age on the rhizosphere microbiome, regardless of the specific community of each field, and despite microbiome responses to climate events.
