Abstract In order to understand the bioinformatics function of pepper CAMTA gene family，explore its gene expression characteristics under abiotic stress，and provide a basis for development of pepper CAMTA gene function and breeding of stress resistance，this study gained pepper CAMTA family members on PlantTFDB website，and analyzed the gene structure，domains，protein tertiary structure，evolutionary relationship，cis-acting element，hormon treatment, and abiotic stress expression．The results showed that there were 5 CAMTA members in pepper，all containing CG-1 conserved structure domains；mainly distributed on 4 chromosomes．There were obvious differences between their gene sizes．The numbers of amino acid were between 89-1 023，and exon numbers were between 1-13．Phylogenetic tree analysis showed that pepper CAMTA gene family could be divided into 3 groups，and the genetic relationship between amino acid sequence of pepper CAMTA and that of tomato was most closely．Results of gene expression analysis showed that the pepper CAMTA gene family had played a role in signal transduction and tissue development process after stress．
