Schematic structure of HMW glutenin gene promoter and the strategy of cloning. The regulatory elements were indicated by boxes, E: E motif, N: N motif, PE: partial HMW enhancer, EN: complete HMW enhancer, TA: TATA box. The specific primers (HGPF and HGPxR) for amplifying x-type HMW glutenin gene promoter and their target region are marked. The deletion of regulatory element partial enhancer in y-type HMW glutenin gene promoter of some species is also indicated by broken lines.
