摘要: GluB-4是水稻种子谷蛋白的编码基因,在种子成熟过程中,由GluB-4启动子调控,在胚乳中特异地表达。以水稻基因组DNA为模板,通过PCR扩增技术得到GluB-4启动子片段,序列分析结果表明:获得的启动子片段的大小为1560 bp,与已报道的该启动子序列相比较,其核苷酸序列同源性为99.8%。该启动子区域含有TATA-box,CAAT-box,GCN4基序,Skn-1基序等胚乳特异表达启动子所必需的正调控元件,同时还含有高水平转录调控因子5UTR Py-rich stretch序列。利用该启动子构建了植物种子特异表达载体pCGB4P,为进一步的研究工作奠定了基础。

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
