Abstract
Changes in different biochemical parameters like total phenolic content,
protein pattern, polyphenol oxidase, peroxidase and isozymes of peroxidase were
compared in sterility mosaic resistant (Hy3C) and susceptible (Type-21) pigeonpea
varieties at different growth stages both under inoculated and uninoculated conditions.
Resistant variety was characterized by the presence of specific isoperoxidase and proteins
but only little difference was recorded between resistant and susceptible variety with
respect to preformed or induced total phenolics and peroxidase activity. The activity of
polyphenol oxidase increased substantially in susceptible variety following infection. Role
of these changes is discussed in relation to disease resistance.
