Transcriptome and Anthocyanin Profile Analysis Reveals That Exogenous Ethylene Regulates Anthocyanin Biosynthesis in Grape Berries

Anthocyanins are important phenolic compounds in grape skins, affecting the color, oxida- tion resistance, and aging ability of red wine. In recent years, global warming has had a negative effect on anthocyanin biosynthesis in grape berries. Ethylene serves as a crucial phytohormone regulating the development and ripening processes of fruit; however, the specific molecular mechanism and the regulatory network between ethylene signaling and the anthocyanin biosynthesis pathway remain...
