Abstract:

Bipolaris maydis is a phytopathogen of maize that causes maydis leaf blight or Southern corn leaf blight disease. The Biploaris maydis produce extracellular enzymes that degrade cellulose, pectin, amylose and amylopectin of the plant cell wall and helps in invasion and virulence of the phytopathogen in the infected tissue. Variations among the seven isolates of Bipolaris maydis were found for extracellular enzymatic activity in solid medium and the amylase activity showed the highest activity index. E15 isolate of Bipolaris maydis showed the highest amylase, pectinase and esterase activity, whereas, E27 isolate showed highest cellulase activity index as compared to other isolates. The results indicated the possible role of cell wall degrading enzymes in the aggressiveness, virulence and increase the disease incidence of the maydis leaf blight of maize.
