Inoculation of plant growth-promoting bacteria attenuates the negative effects of drought on sorghum.

Microbial inoculants are suitable cost-effective technology to help plants endure drought. For the development of commercial inoculants, screening of efficient plant growth-promoting bacteria (PGPB) is a crucial step. The aim of this study was to evaluate the performance of PGPB to modulate drought resistance in Sorghum bicolor.
