How does host genotype affect plant #microbiomes? @maggieRwagner explores a new #PLOSBiology study showing how host genotype leads to differential gene expression & fitness in bacteria of the #barley #rhizosphere. Primer: https://plos.io/3xYne3n Paper: https://plos.io/4aQX4Oy

Barley plants fine-tune their root microbial communities through sugary secretions
The custom community of beneficial microbes improve the plants’ growth

Different types of #barley recruit distinct communities of soil #microbes to grow around their roots by releasing a custom mix of sugars and other compounds, according to a new study.

Plants secrete #RootExudates into the #rhizosphere to attract microbes. @albapacmo &co show that #barley genotype exerts multi-level selective pressure on soil #Pseudomonas, affecting abundance, genotype & gene expression @JohnInnesCentre #PLOSBiology https://plos.io/4aQX4Oy

Uncovering the dominant role of root metabolism in shaping #rhizosphere metabolome under drought in tropical rainforest plants: Gina Hildebrand et al. https://www.sciencedirect.com/science/article/abs/pii/S0048969723043127

"as roots respond to drought, their microbial communities adapt, reinforcing the #DroughtTolerance of the plant. These species-specific interactions systematically change with the root #metabolome under drought conditions."
