Journal ArticleDOI
Drought and host selection influence bacterial community dynamics in the grass root microbiome.
TL;DR: It is shown that there is a strong correlation between host phylogenetic distance and the microbiome dissimilarity within root tissues, and that drought weakens this correlation by inducing conserved shifts in bacterial community composition.
Journal ArticleDOI
Drought delays development of the sorghum root microbiome and enriches for monoderm bacteria

TL;DR: It is demonstrated that under drought, roots increase the production of many metabolites, and that monoderms inhabiting the drought-treated rhizosphere exhibit increased activity of transporters connected with some of these same compounds.
Journal ArticleDOI
Transcriptomic analysis of field-droughted sorghum from seedling to maturity reveals biotic and metabolic responses.

TL;DR: A large-scale depletion in the expression of genes critical to arbuscular mycorrhizal (AM) symbiosis is discovered, with a corresponding drop in AM fungal mass in the plants’ roots.
