Abstract:
There was an increase in the activity of peroxidase, catalase, Phenylalanine ammonia lyasetotal phenols, and total free amino acids in all the genotypes when inoculated with M. phaseolina. Whereas, there was decrease in the activity of total sugar, reducing sugar and non-reducing sugar in all the chickpea genotypes upon inoculation with M. phaseolina. Highest enzymatic activity and sugar content was recorded in moderately resistant genotypes viz., Phule G 12107, NDG 13-21 and IPC 2010-112 compared to susceptible genotype GNG 2228and highly susceptible genotype L550. The enhanced biochemical activities during plant pathogen interaction triggers the defense related enzymes such as lignin, suberin, wall-bound phenolics, flavonoids, lignin, induction of hypersensitive reaction (HR) etc., which resulted in cell strengthening and enhances resistance to pathogen. The depletion of sugars during host-parasite interaction might be due to increased utilization of sugars by the fungi for energy and synthetic reactions involved in multiplication of the pathogen.
