DgMYB4 orchestrates anthocyanin modification and acyl-glucose donor biosynthesis in Delphinium grandiflorum.
The results support a model in which DgMYB4 contributes to coordinated regulation of core anthocyanin biosynthesis, downstream modification, and acyl-glucose donor-related processes and identify DgMYB4 as an important candidate regulator linking anthocyanin accumulation with downstream structural modification in Delphi...
