The pathogenicity of phytopathogenic fungi is primarily associated with plant cell walldegrading enzymes (PCWDE). These enzymes include pectinases, xylanases, cellulases, amylases and cutinases. Rhizoctonia solani AG-1 IA is considered an important plant pathogen affecting a wide range of host crops of global importance. Knowing the dynamics and control of this pathogen is of utmost importance for the agricultural sector. On the other hand, there is a very large focus on the study of these enzymes because of their ability to degrade plant biomass for biofuel production. Thus, if EDPCP produced by R. solani AG-1 IA are efficient in the hydrolysis of plant biomass, these may be used or associated with biotechnological processes aimed at producing new products. Consequently, it is proposed to sequence the genes for these enzymes, and to analyze these nucleotide sequences in different hosts. In this case, it should be possible to correlate molecular differences between the enzymes produced by R. solani AG-1 IA, following infection of different hosts and to determine whether the enzymes show difference from other similar microbial enzymes.
