The soybean vegetative storage protein genes VspA and VspB encode vacuolar glycoprotein acid phosphatases. Transcription of the Vsp is synergistically activated by jasmonic acid or methyl jasmonate (MeJA) and soluble sugars. The action of these modulators is mediated by two different DNA domains in the VspB promoter. In this study, we present new data regarding VspB regulation by sucrose and inorganic phosphate, which suggest a common mechanism of transcriptional control for Vsp and other sugar… CONTINUE READING
