Utilization of Indigenous Endophytic Microbes for Induction of Systemic Resistance (ISR) in Soybean (Glycine Max (L) Merril) Against Challenge Inoculation with F. oxysporum

Abstract

Present study was carried out to investigate the effects of indigenous endophytic microorganisms Pseudomonas sp., Bacillus sp., Burkholderia sp. Streptomyces sp., Actinoplanes sp., Alternaria sp., and Fusarium sp. on induction of systemic resistance (ISR) against challenge inoculation with Rhizoctonia solani in soybean (Glycine max (L) Merril). It was observed that treatment with endophytes significantly (p<0.05) elevated the levels of marker biochemicals viz., phenols, peroxidase (PO), phenylalanine ammonia-lyase (PAL), polyphenoloxidase (PPO), b-1, 3-glucanase and chitinase involved in ISR in soybean. The significant increments were recorded in protein content. Thus; present studies indicate that utilization of indigenous endophytes may exert more favorable effects on plant health which ultimately will enhance crop productivity.
