Functional analysis of a pomegranate [Punica granatum L.] MYB transcription factor involved in the regulation of anthocyanin biosynthesis

ABSTRACT

Background: pomegranate fruit [Punica granatum L.] is a rich source of anthocyanin pigments resulting in vibrant colours and anti-oxidant contents. Although the intensity and pattern of anthocyanin biosynthesis in fruit are strongly influenced by R2R3-MYB transcription factors, little is known about the regulation and role of MYB in anthocyanin pathway of pomegranate
