“…The PGPR applications, in general, substantially enhanced the dry matter accumulation in root and shoot and whole plants, N and P in root and shoot, respectively, Withaferin-A concentration in roots and total withanolide content in plants relative to control. Among all PGPR, B. sonorensis, however, had significantly maximum beneficial impact on all the measured biological factors such as height, girth, root and shoot dry weight of plants and withanolide concentration [178]. The increase in the plants' activity was attributed to inoculation of B. sonorensis, which possessed several PGP activities such as P solubilisation, IAA secretion, siderophore, amylase, ammonia and HCN production.…”
