Functional Descriptions
- VvBBX44 and VvMYBA1 form a regulatory feedback loop to balance anthocyanin biosynthesis in grape.
- The expression of VvMYBA1 increased earlier than that of VvBBX44 during berry skin development, and exogenous anthocyanin treatment increased VvBBX44 expression.
- VvMYBA1 directly activates VvUFGT and VvBBX44 expression. Although VvBBX44 does not physically interact with VvMYBA1, these two proteins form a feedback regulatory loop to balance anthocyanin biosynthesis in grapevine.
- Our study highlights the regulatory roles of VvBBX44 and VvMYBA1 in anthocyanin biosynthesis and sheds light on a feedback regulatory loop that balances this process in grapes.
- A regulatory gene, VvMYBA1, which could activate anthocyanin biosynthesis in a transient assay, was recently shown not to be transcribed in white berries due to the presence of a retrotransposon in the promoter.
- Color recovery in berries of grape (Vitis vinifera L.) ‘Benitaka’, a bud sport of ‘Italia’, is caused by a novel allele at the VvMybA1 locus.
- Expression analysis of VvMybA1 and genes in the anthocyanin biosynthesis pathway.
- Found that the VvMybA1 locus of ‘Benitaka’ is heterozygous for the VvMybA1a allele (non-functional) and a novel VvMybA1BEN allele, and that VvMybA1BEN restored VvMybA1 transcripts.
- These findings suggest that the expression of VvMybA1 is essential for the coloring of grape berry skin.
