摘要：

In the genome of the model legume Lotus japonicus, dihydroflavonol 4-reductase (DFR), which is the first committed enzyme of the anthocyanin and proanthocyanidin (PA) pathways, is encoded as a tandemly arrayed five-gene family. Expression analysis revealed that both organ specificity and stress responsiveness differ among the DFRs. To elucidate the regulatory mechanisms underlying the expression of DFRs, we investigated the transcriptional control of each member of the DFR multigene family. Ectopic expression of a combination of the transcription factors MYB, bHLH, and WDR showed that only the DFR2 promoter was activated, indicating that each member of the DFR gene family is regulated independently.
