Genome-wide characterization of the chitinase gene family in wild apple (Malus sieversii) and domesticated apple (Malus domestica) reveals its role in resistance to Valsa mali.

ABSTRACT: Chitinases are responsible for catalyzing the hydrolysis of chitin and contribute to plant defense against fungal pathogens by degrading fungal chitin. In this study, genome-wide identification of the chitinase gene family of wild apple (Malus sieversii) and domesticated apple (Malus domestica) was conducted, and the expression profile was analyzed in response to Valsa mali infection. A total of 36 and 47 chitinase genes belonging to the glycosyl hydrolase 18 (GH18) and 19 (GH19) families were identified in the genomes of M. sieversii and M. domestica, respectively. These genes were classified into five classes based on their phylogenetic relationships and conserved catalytic domains. The genes were randomly distributed on the chromosomes and exhibited ex
