Inoculation of endophytic bacteria on host and non-host plants-Effects on plant growth and Ni uptake

► Inoculation of endophytic bacteria, Pseudomonas sp. A3R3 increased the biomass of Brassica juncea and Ni content of Alyssum serpyllifolium. ► Pseudomonas sp. A3R3 showed the potential to produce plant growth promoting substances and plant polymer hydrolyzing enzyme. ► This strain also exhibited high level of colonization in the tissue interior of both plant species.
