The Endophytic Root Microbiome Is Different in Healthy and Ralstonia solanacearum-Infected Plants and Is Regulated by a Consortium Containing Beneficial Endophytic Bacteria

Abstract

Bacterial wilt disease causes heavy yield losses in many crops. Endophytic microbiomes play important roles in control of plant diseases. However, the role of the endophytic root microbiome in controlling bacterial wilt disease is poorly understood. Here, differences in endophytic root microbiomes and network structures between healthy and diseased tobacco plants are reported. A synthetic microbial consortium containing beneficial endophytic bacteria was used to regulate the endophytic microbiome and attenuate bacterial wilt disease. The results could be generally used to guide control of bacterial wilt disease.
