    Abstract:
    To use different types of promoters in transgenic rice research, the 5'-upstream regulation region of rice Rubisco small subunit gene (rbcS) was cloned from a Chinese cultivar Wuyunjing 8, and its sequences were confirmed by comparison with the known genome sequences of both japonica and indica rice. The cloned rbcS promoter was fused to the 5'-upstream of GUS (beta-glucuronidase) coding region in a binary vector, and introduced into rice by Agrogacterium-mediated transformation. The integration of the rbcS-GUS fusion gene in transgenic rice was confirmed by PCR analysis. The results of both histochemical staining and quantitative analysis of GUS activity showed that the expression level of GUS fusion gene was significantly stronger in leaf blade and sheath than in other organs of transgenic rice plants, and the GUS activity was restricted to the mesophyll cells of leaf tissue, which showed that the rice rbcS promoter could control not only the tissue- but also the cell-specific expression of foreign genes in transgenic rice. The present results also demonstrated that light induction had a significant effect on the enhancement of transgene's expression when regulated by the rice rbcS promoter in transgenic rice. Our results showed that the rice rbcS promoter might be very useful for the expression of target genes in transgenic rice, with particularly high efficiency in leaf tissues.
