Alleviation of water-deficit inhibition of plant growth by rhizosphere microbiota conditioning.

ABSTRACT: Rhizosphere microbiota conditioning is a promising strategy to enhance plant growth. We conditioned the rhizosphere microbiota of Brassica juncea to water deficit to assess its impact on plant growth. In a glasshouse, plants were first grown under well-watered conditions, then exposed to moderate (MD, pF = 2.3) or extreme (ED, pF = 3.5) water deficits. We extracted and inoculated the rhizosphere microbiota to new plants and repeated this process 10 times. Control plants were kept well-watered. We monitored changes in plant phenotypes and in rhizosphere microbial communities (bacteria and eukaryotes). The initial water-deficit growth inhibition of plants was successfully alleviated by 19.3% in MD and 29.4% in ED after conditioning (MD: from -35.6% to -16.3%; ED: from -56.8% to -27.4%). This
