ABSTRACT
The WD40 superfamily plays an important role in a wide range of developmental and physiological processes. It is a large gene family in eukaryotes. Unfortunately, the research on the WD40 superfamily genes in Cerasus humilis has not been reported. 198 ChWD40s were identified and analyzed in the present study, along with evolutionary relationships, gene structure, chromosome distribution, and collinearity. Then, 5 pairs of tandem duplication and 17 pairs of segmental duplication were found. Based on RNA-Seq data analysis, we screened 31 candidate genes whose expression was up-regulated during the four developmental stages of fruit peel. In addition, we also demonstrated that ChWD40-140, namely ChTTG1, located in the nucleus, cytoplasm, and cytomembrane, has transcriptional activation activity and can form homodimers. ChTTG1 is involved in anthocyanin biosynthesis through heterologous overexpression in Arabidopsis. These research results provide a reference for a comprehensive analysis of the functions of WD40 in the future.
