Characterization of Cell Wall Degrading Enzymes of Rhizoctonia solani AG-3 from Tobacco Target Spot

Article Preview

Abstract:

Rhizoctonia solani Kühn is a causal pathogen responsible for many types of plant disease worldwide and a major soilborne fungal pathogen that severely impairs yield and quality of tobacco worldwide. Activities, pathogenicity of the cell wall-degrading enzymes produced by the Rhizoctonia solani from tobacco target spot disease both in liquid medium and in tobacco tissue were studied. The result showed that R. solani from tobacco can produce pectinase and cellulase both in vitro and vivo, and the activity of PG and PMG was the highest in vitro. The activity of Cx and β-glucosidase was the highest in vivo, and enzyme production ability of strong pathogenicity strains is stronger than the weak pathogenicity strains in vitro.
