Abstract: Based on previous transcriptome data,a root-specific expression gene of common wild rice(Oryza rufipogon Griff.)was screened,and the promoter sequence was cloned and designated as OrRSGp. It was 896 bp in length and contained main functional elements such as CAAT-box and TATA-box,MeJA-responsiveness and some elements involved in defense and stress responsiveness. It was fused with the β-glucuronidas(gus)reporter gene and transformed into Arabidopsis thaliana. GUS histochemical staining and quantitative analysis showed that OrRSGp regulated gene gus specific expression in roots.

Key words: common wild rice, promoter, root tissue-specific expression
