Transcriptomic analysis identifies VvMYB90 and VvNAC92 as key regulators mediating anthocyanin biosynthesis and fruit color differentiation in three grape cultivars

Key Points

• VvMYB90 and VvNAC92 regulate anthocyanin biosynthesis and fruit coloration, enhancing grape diversity.
• Transcriptomic analysis revealed differential expression of VvMYB90 and VvNAC92 in three grape cultivars.
• This analysis leveraged RNA sequencing to identify key regulators influencing color and compound profiles.
• Findings suggest that targeted breeding could enhance color quality in grape varieties, impacting winemaking.
