Microbial endophytes are known to induce systemic resistance in host plant. 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
elevated the levels of marker biochemicals viz., phenols, peroxidase (PO), phenylalanine ammonialyase
(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.
