Abstract:

In order to know the distribution and structural features of hypothetical chitin-binding protein in Magnaporthe grisea database, which would may a good foundation on further research in the encode genes function. In this paper, bioinformatics approaches were used to analysis the domains, subcellular localization EST and phylogenetic tree construction of putative chitin binding proteins (CBP) in the genome of Magnaporthe oryzae, and predicted the gene expression characteristics in different developmental stages and different tissue. In total, 23 putative CBP family proteins were retrieved from the genome, which distributed inequable in seven chromosomes, the majority of CBP were localized in the extracellular. The expression of CBP in different developmental stages and different tissues were different in Magnaporthe oryzae. The chitin binding proteins interlaced between different species fungi, the evolutionary relationship was complicated between them.
