Profiling, isolation and characterisation of beneficial microbes from the seed microbiomes of drought tolerant wheat

Abstract Climate change is predicted to increase the incidence and severity of drought conditions, posing a significant challenge for agriculture globally. Plant microbiomes have been demonstrated to aid crop species in the mitigation of drought stress. The study investigated the differences between...
