Abstract

Abstract: In order to understand the characteristics of the β-ketoacyl-CoA synthase（KCS）gene family in the Capsicum annuum genome deeply，all KCS gene family members were identified by using the bioinformatics methods，hereafter，the genes chromosomal location，phylogenetic relationship，gene structure，protein conserved motifs，tissue expression pattern and response to high temperature，low temperature and NaCl stress were analyzed. The results showed that a total of 22 KCS genes were identified and distributed on 9 chromosomes. Phylogenetic analysis indicated that the CaKCS were divided into 4 groups，and each of them included different numbers of genes which contained 0–3 introns and 6–14 conserved motifs. Each gene in the KCS family has different expression patterns，and the CaKCS could be repressed or activated by high temperature，low temperature and NaCl treatment.

Key words: pepper, KCS gene family, gene expression
