Halophilic rhizobacteria promote growth, physiology and salinity tolerance in <i>Sesamum indicum</i> L. grown under salt stress.

ABSTRACT:

Introduction

Salt stress is a major global issue that negatively affects plant growth and physiological processes. Plant growth-promoting rhizobacteria (PGPR) are known to alleviate salt stress and promote plant growth. This study aimed to isolate and characterize salt-tolerant PGPR from salinity-affected soils in Tamil Nadu, India, and assess their potential to enhance growth and salt tolerance in sesame (Sesamum indicum L.).

Methods

Salt-tolerant PGPR were isolated and screened for plant growth-promoting traits. One isolate, designated PAS1, demonstrated significant capabilities, including the production of indole-3-acetic acid (IAA; 48.56 μg ml^-1), siderophore production (89.20 ± 0.65%), phosphate solubilization (7.8 mm zone of clearance), ammonia, and h
