Identification and characterization of DFR gene family and cloning of candidate genes for anthocyanin biosynthesis in pepper (Capsicum annuum L.).

ABSTRACT: Dihydroflavonol-4 reductase (DFR) is a key enzyme in plant anthocyanin synthesis and can affect the synthesis of anthocyanin. In order to explore the role of DFR in anthocyanin synthesis of capsicum, the sequence of the DFR gene family was downloaded from the Arabidopsis genome database. The study showed the presence of nine members of the DFR gene family in pepper, which are primarily localized in the cytoplasm and chloroplasts. The majority of these proteins exhibit hydrophilic characteristics, with their secondary structure predominantly consisting of α-helices and random coils. Furthermore, these genes can be categorized into four distinct subfamilies, with the gene structure and conserved motifs of CaDFR members within the same subfamily providing robust support for this classificatio
