Genome-wide analysis of chalcone synthase (CHS) family from eggplant (Solanum melongena L.) in flavonoid biosynthetic pathway and expression pattern in response to heat stress

In this study, a genome-wide analysis about SmCHS genes family in eggplant was performed. The CHS protein biochemical characteristics, phylogenetic relationships, gene structures, cis -regulatory elements, regulatory network and functional predictions of the family members were examined. It is revealed that SmCHS genes family have conservation gene structure and functional diversification. CHS play important roles to anthocyanin biosynthesis pathway, exhibited two or more expression patterns and execute multiple functions to regulate anthocyanin content in eggplant peel under heat stress. This work will make eggplant for further research of functions, regulation and evolution of the CHS family.
