Comprehensive Analysis of the Chitinase Family Genes in Tomato (Solanum lycopersicum).

ABSTRACT: Chitinase catalyzes the hydrolysis of chitin β-1,4 linkages. However, plants cannot produce chitin, suggesting that plant chitinases do not have the same function as animals. This study investigated the chitinase gene family in tomato and divided into eight groups via phylogenetic analyses with Arabidopsis and rice members. Conserved gene structures and motif arrangements indicated their functional relevance with each group. These genes were nonrandomly distributed across the tomato chromosomes, and tandem duplication contributed to the expansion of this gene family. Synteny analysis also established orthology relationships and functional linkages between Arabidopsis and tomato chitinase genes. Several positive selection sites were identified, which may contribute to the func
