Functional role of Pseudomonas rhizobacteria in enhancing plant growth under stress-adaptive agricultural systems

Abstract

This study explores the functional traits of Pseudomonas spp. isolated from rhizospheric soils and their potential as plant growth-promoting rhizobacteria (PGPR). Four isolates were selected and characterized based on morphological, physiological, and biochemical parameters. The results demonstrated their tolerance to various abiotic stresses, resistance to heavy metals and pesticides, and ability to produce plant-beneficial compounds, including siderophores, hydrogen cyanide, and indole-3-acetic acid. Although certain PGPR traits were absent, the overall profile indicates the potential utility of these isolates in sustainable agriculture and stress-prone environments.
