A VIVIPAROUS1-like transcription factor, PvALF, is known to activate storage protein genes through the RY element in their promoters in maturing common bean seeds. This element also exists in the promoter of the gene for a cysteine proteinase, EP-C1, which is expressed in a germination-specific manner. We show that the EP-C1 gene expression is suppressed through interaction of PvALF with the RY element in the EP-C1 promoter.

Keywords: Keywords: Germination — Phaseolus vulgaris — Proteinase — PvALF — VIVIPAROUS1.; Abbreviations: CaMV, cauliflower mosaic virus; DAI, days after imbibition started; GUS, glucuronidase.
