Abstract: The GluB-4 promoter was amplified from Oryza sativa genome by polymerase chain reaction and cloned into pGEM-T Easy vector. Sequence analysis showed that the obtained promoter fragment 1560 nucleotides and showed homology of 99.8% with the reported GluB-4 promoter. Also, the obtained promoter fragment includes TATA-box, CAAT-box and the two cis-regulatory elements, GCN4 motif and Skn-1 motif, which are necessary to mediate endosperm expression of the GluB-4 glutelin gene. The plant expression vector pCGB4P was constructed by the GluB-4 promoter.

Key words: Oryza sativa, GluB-4 gene, Promoter, Glutelin
