摘要
[ Objective ] This study aimed to investigate the expression of IPT gene directed by GmSARK promoter in Arabidopsis. ~ Method J IPT gene and C.m- SARK promoter were respectively cloned to construct plant expression vector and transform Arabidopsis. Tl transgenie plant lines were detected by PPT （ phosphino- thricin） herbicide selection and treated under drought and dark conditions for semi-quantitive RT-PCR analysis. E Result] GmSARK： ：IPT fusion gene was success- fully cloned and the plant expression vector p3301-GmSARK-IlYF was constructed. RT-PCR analysis showed that the target gene was expressed in T1 transgeuie plant lines at the mRNA level. [ Conclusion] This study laid the foundation for further investigating the roles of IPT gene directed by GmSARK promoter in plant stress resistance.
