Abstract : Salinity stress is one of the major abiotic stresses, which deleteriously affects plant growth development and crop productivity; various approaches have been done to ameliorate the adverse effect of salinity stress such as seed priming, Augmentation of various exogenic materials and development of the transgenic plants, etc. The current study was to investigate the isolated and identified mangrove endophytic bacteria from Avicennia marina from the red sea Jeddah coastal region of Saudi Arabia and explore its alleviating effects against salinity stress in mung bean (Vigna radiata). The isolate was identified as Bacillus halotolerans YMK021. The potential of this endophytic bacteria was exploited to alleviate the salinity stress in crop plant mung bean (Vigna radiata). Five different NaCl concentrations (150 -550mM) were examined with or without YMK021 in the Mung bean plant, in response to salinity stress the plant treated with YMK021 showed a significant response towards the oxidative damage that occurs during stress by producing antioxidants such as POD, CAT, and PPO. The other parameters like water use efficiency (WUE), stomatal conductance (GS), transpiration rate (E), photosynthetic rate (A), and morphological parameters compared to control and the plant contains only NaCl. The study concludes that the application of endophytic bacteria from the halophytes like mangroves can confer the glycophytic crop or any other crop plant a similar salt-resistance potential and boost the plant growth and crop productivity.
