Abstract
Biochemical changes in the leaves of mungbean yellow mosaic virus (MYMV) resistant (ML-267) and suceptible (ML-5) varieties have indicated that the MYMV infection results in malfunctioning of polyphenol metabolism by increasing total sugars, free amino acids, total phenols in both the varieties, whereas ortho-dihydroxy phenol and flavonols only in the resistant variety as compared to their respective healthy ones. Polyphenol oxidase activity increased in resistant variety wheras it decreased in susceptible one with infection. Phenylalanine ammonia-lyase, tyrosine ammonia-lyase, and peroxidase activity decreased with MYMV infection in both the varieties.
