A Myb transcription factor, PgMyb308-like, enhances the level of shikimate, aromatic amino acids, and lignins, but represses the synthesis of flavonoids and hydrolyzable tannins, in pomegranate (Punica granatum L.)
We cloned and characterized a subgroup S4 R2R3 Myb transcription factor, PgMyb308-like. Overexpressing PgMyb308-like in pomegranate hairy roots. Transcriptome analysis of PgMyb308-like-overexpressing hairy roots revealed reprogramming of cell wall-related genes, while overexpression of PgMyb308-like in Arabidopsis thaliana plants uncovered its distinct role in a different genetic and metabolic background. The results suggest that PgMyb308-like activates genes in the shikimate pathway and lignin biosynthesis, but suppresses those involved in the production of HTs and flavonoids. Overall design: Examination of 3-month old transgnic pomegranate hairy roots
