Plant β-1,3-glucanases are pathogenesis-related (PR) enzymes that hydrolyze β-1,3-glucans in fungal cell walls, compromising their structural integrity and inhibiting pathogen growth. These enzymes, along with phytoalexins, constitute key components of plant–pathogen interactions. In this study, the role of β-1,3-glucanase in elicitor-induced defense responses was investigated in resistant (Jaki-9812, Gulak-1), moderately resistant (AKG-46), and susceptible (Chafa-1) cultivars of chickpea (Cicer arietinum L.) against Fusarium oxysporum. Enzyme activity was assayed spectrophotometrically using laminarin as substrate. Results demonstrated rapid induction of β-1,3-glucanase activity in resistant cultivars within 5 hours post-elicitation, peaking at 40–45 hours. Fusarium conidial suspension was the most effective elicitor, followed by reduced glutathione (abiotic) and fungal cell wall elicitor. Tissue-specific expression was highest in cotyledons and roots, and lowest in epicotyls. The study concludes that β-1,3-glucanase activity, along with salicylic acid accumulation, serves as a biochemical marker for disease resistance and plays a vital role in systemic acquired resistance (SAR) in chickpea.
