Abstract
Salinity is a major abiotic stress that negatively impacts plant health and soil microbiota. ACC (1-aminocyclopropane carboxylic acid) deaminase producing microorganisms act as natural stress busters that protect plants from different kinds of stresses. The study focused on the isolation of potent, indigenous, multi-trait ACC deaminase producers. The shortlisted ACC deaminase producers were checked for their ability to promote growth of Cajanus cajan, and mitigate stress under laboratory conditions followed by validation of their potency in naturally saline field conditions. Physiological stress markers were assessed to evaluate the impact of salinity in plants treated with ACC deaminase producer, compared to controls. Further, the contribution of ACC deaminase in stress mitigation was demonstrated by using a chemical inhibitor for ethylene biosynthesis. This study presents a polyphasic approach, transitioning from the rhizospheric soil to the laboratory to validation in the field, and puts forth a promising eco-friendly alternative for sustainable agriculture.
