Isolation of salt-tolerant Pseudomonas strains with potential for alleviation of salt stress in peanut plant (Arachis hypogaea L.)

Plant growth-promoting rhizobacteria (PGPR) is a promising solution to improve plant growth under salt stress. Among PGPR, Pseudomonas genus of bacteria that possesses variety mechanisms in promoting and inducing resistance biological as well non-biological This study aimed isolate the from salty-contaminated rhizosphere root collecting at Nam Dinh, also investigate their functions peanut seedlings salty conditions. Nine were isolated, but only seven them identified by Pseudomonas-specific primers. Two those isolates, ND06 ND09, chosen based on characteristics such production indole-3-acetic acid (IAA), phosphate solubilization, nitrogen fixation. In addition, both two strains carried coding gene for 1-aminocyclopropane-1-carboxylate (ACC) deaminase which plays an important role supporting plants withstand various stress Especially, ND09 strain improved parameters normal conditions; while presented enhancement not These results suggest may be used agent eco-friendly agricultural practices future.
