Abstract: Estimation of alteration in protein content due to the infection of Fusarium solani causing wilt disease was carried out in various plant parts of Cyamopsis tetragonoloba. The infection of Fusarium solani is characterized by yellowing of lower leaves and stunting or dwarfing of plant growth. Symptomatic seeds carried white fungal growth of the pathogen. Estimations of protein content and its related enzyme were carried out in leaves, stem and seeds of healthy and infected counter plant parts. The alteration in protein contents were recorded in plant parts. Protein content was higher in case of healthy plant parts 0.296, 0.236 and 0.290 mg/gm in leaves, stem and seeds respectively while in wilt infected counterparts viz. leaves, stem and seeds it was 0.172, 0.132 and 0.206 mg/g. Protease activity was higher in case of wilt infected plant parts 0.017, 0.007 and 0.008 units/ sec/mg of fresh weight of tissue of leaves, stem and seeds whereas it was 0.008, 0.005 and 0.006 units/ sec/mg of fresh weight of tissue in healthy counterparts.
