Abstract:

This paper presents a comprehensive study on identifying the number of genes encoding different classes of plant cell wall degrading enzymes in the genomes of pathogenic and nonpathogenic fungi. Plant pathogenic fungi secrete extracellular enzymes that are able to degrade the plant cell walls of their host plants. These plant cell wall degrading enzymes are so necessary for penetration of the cell wall barriers, as well as for generation of simple molecules that can be assimilated for growth. Initially, BLAST was exerted to compare pathogenic (M.grisea, F.graminearum) and non?pathogenic fungi (N.crassa, A.nidulans) and the top hits of them were acquired. Then SignalP were performed to verify whether these PCWDEs would be secreted by the fungi.Consequently, we conclude that some significant biological differences of PCWDEs can be discovered between pathogenic and nonpathogenic fungi.
