Abstract

RUS1 was one of the disease resistance gene analogs obtained from Setaria italica Beauv. Semi-quantitative RT-PCR analysis result showed that RUS1 gene could be induced by Uromyces setariae-italicae and had relation to the resistance response of Setaria italica Beauv. against Uromyces setariae-italicae infection. Promoter sequence of RUS1 was obtained by the method of Genome Walking, and its length was 675 bp. RUS1 promoter and pCAMBIA1300 vector were fused to construct RUS1∷GUS vector. GUS histochemical staining result showed that promoter could activate gene expression. RUS1 gene (including the promoter sequence) was obtained through PCR amplification and then fused with pCAMBIA1300 vector to construct pCAMBIA1300∶RUS1 plant expressing vector. The research laid a foundation for gene functional identification of RUS1.

Key words： Setaria italica; RUS1; semi-quantitative RT-PCR; GUS histochemical staining; plant expressing vector
