Description Biochemical changes in sorghum cultivars naturally infected with maize mosaic virus were
investigated. Virus infection reduced plant biomass ranging from 10-53% among different cultivars. Total
chlorophyll content in infected leaves was reduced. Reduction in nitrate reductase activity varied from 23-72%
in the infected leaves of different cultivars but nitrate reductase activity in the stems of infected plants was
significantly higher than in those of healthy plants. The relationship between plant biomass and leaf
chlorophyll concentration was positive and that between plant biomass and stem nitrate reductase activity
was negative. The relationship between plant biomass and stem N concentration was negative. Concentration
of soluble sugars in leaves and stems of infected plants was increased. N concentration in the infected leaves
was lower than in the healthy leaves but the N concentration in infected stems was higher. Electrophoretic
analysis of soluble leaf proteins revealed the presence of two polypeptides of 21 and 22 kD in the infected but
not in the healthy leaves and these were found to be not of viral origin by electro-blot immunoassay.
