- Abstract:
The synthesis of anthocyanins in higher plants involves many enzymatic
steps. Here we describe the isolation and characterization of a cDNA,
ant17, which encodes a protein that has 73% amino acid sequence identity
with the candi gene product of Antirrhinum majus and 48% with that of the
maize a2 gene. This protein may therefore be involved in the synthesis of
anthocyanins in the steps after the action of dihydroflavonol 4-reductase.
This is consistent with the absence of ant17 expression in the regulatory
anthocyanin mutants of petunia an1, an2 and an11. Furthermore, ant17 is
predominantly expressed in corollas and anthers and is induced by
gibberellic acid.
