title: Soybean growth-promotion by Pseudomonas sp. strain VS1 under salt stress.
abstract: In the present study, we employ Pseudomonas sp. strain VS1 showed in vitro plant growth-promotion characteristics and promoted soybean seed emergence under salt stress. Strain produced indole 3-acetic acid in the presence of salt stresses that exhibited high numbers of lateral root as compared to control. Bacterial strain exhibited growth in DF salt medium amended with 1-aminocyclopropane-1-carboxylate through ACC deaminase activity. Bacterial-treated soybean seeds were subjected to salt stress and significantly enhanced emergence at 7 days after seeding. Strain untreated soybean plants had a 33% seed germination when 200 mM NaCl was applied at 0 DAS and the root length was significantly decreased compared to the strain treated plants (LSD0.05 = 0.21). Most importantly, the application of 200 mM NaCl at 0 DAS resulted in only a 9% of lateral root in untreated plants as compared to strain treated plants.
