In germinating wheat embryos, gl-OXO accumulation is localized in cell wall. It has been confirmed that this enzyme locally provides H2O2 to catalyze peroxide-mediated cross-linking of cell wall components in terminal cellular dif ferentiation and plays an important role in enabling cells to retain their meris tematic and organogenic capacity. Using tail-PCR and DNA sequencing techniques, we isolated Germin-like Protein 3 promoter sequence(1 654 bp), from common wheat cultivar (yumai 18) genome. No GGGCGGG sequence exiting in promoter implies tha t germin-like protein 3 is not "house-keeping" protein. The presence of TGTCTC, an auxin response element and localizing at upstream -258, indicates that this p romoter is auxin-inducible. The TATA box situates in upstream -27^-32 and 5’-UTR consists of 95 bp.
