Chalcone isomerase (CHI) is a key enzyme involved in anthocyanin metabolism. Previous research on CHI has mainly focused on cDNA cloning and gene expression. In the current study, the 1425-bp potato CHI promoter (PCP) was isolated from four potato cultivars (Heijingang, Zhongshu 7, Désirée, and Favorita) using PCR and DNA sequencing. The PCP contained many cis-regulatory elements (CREs) related to anthocyanin metabolism, tissue specificity, light response, stress, and hormone induction.
