Herbaceous peony PlACLB2 positively regulates red petal formation by promoting anthocyanin accumulation.

ABSTRACT: ATP-citrate lyase (ACL) gene catalyzes the formation of acetyl-CoA to provide intermediate precursors for many secondary metabolites, and also plays an important role in anthocyanin biosynthesis of plants. Herbaceous peony (Paeonia lactiflora Pall.) is an international cut flower known for its rich flower colors, however, the function of the ACL gene in flower color regulation is still unclear. Here, double-colored P. lactiflora 'Hebao Jinlian' were used to study the molecular mechanism of red petal, and acetyl-CoA and anthocyanin biosynthesis related PlACLB2, PlCHS, PlDFR, PlANS, and PlbHLH1 genes were initially found to highly expressed in the red outer-petals. The expression pattern of PlACLB2 was consistent with the
