摘要：AbstractAnthocyanin is abundant in a few vegetables, including eggplant. It protects plants from abiotic stress and benefits human health, making the research of anthocyanin biosynthesis increasingly important. Flowering time is an important reference for judging reproduction and adaptability, which can guide plant production. In this study,SmbHLH13from eggplant was identified. Yeast one-hybrid and dual-luciferase assays showed thatSmbHLH13binded and activated the expression of structural genesSmCHSandSmF3Hin anthocyanin biosynthesis and it also was bound to the promoter of the key geneSmFTin flowering.Furthermore, genetic transformation ofArabidopsisrevealed that overexpression ofSmbHLH13enhanced anthocyanin accumulation and delayed flowering. These results demonstrated thatSmbHLH13might promote anthocyanin accumulation through positive regulation ofSmCHSandSmF3H. Moreover,SmbHLH13might have a role in delaying eggplant flowering.
