Variation of Nitrate Reductase Activity in Rumex Maritimus Linn. During Infection With Ustilago Parletoreii F.A.Wald

Abstract

The present study deals with the variation of nitrate reductase activity in Rumex maritmus Linn. during infection with smut fungus, Ustilago parletoreii F.A.Wald. It is an annual herb growing wild in different marshy places of Manipur, India. The leaves are cooked as vegetable curry items by the local people. The plant is often infected with smut fungus mostly at the midrib and soft portion of the stem (shoot). During the infection with smut fungus Ustilago parletoreii, different enzymatic activities changes were taken placed. There is a fluctuation of nitrate reductase activities amongst the degree of diseases response during infection of plant by this fungus. The maximum activity was found in the pre-sporulation stage of infected plants and chilling spores.
