大豆GmPM31基因启动子响应高温高湿胁迫的功能分析
Functional Analysis of Soybean GmPM31 Gene Promoter Involvement in Response to High Temperature and Humidity Stress
摘要
Abstract
[Objective]To study the function of GmPM31 promoter on seed vigor formation in response to high temperature and high humidity stress,and to lay a foundation for comprehensively unravelling the function of soybean small heat shock proteins involved in the response to high temperature and high humidity stress.[Method]Homozygous T3 transgenic Arabidopsis thaliana with GmPM31 promoter was treated with high temperature and high humidity stress(40℃/100%relative humidity),and wild-type A.thaliana was used as control to detect its tolerance and stomatal opening.Analysis of GUS gene expression driven by the soybean GmPM31 promoter by GUS histochemical staining and quantitative real-time PCR.The seed vigor was detected by 2,3,5-triphenyltetrazolium chloride(TTC)staining.[Result]Compared with the control group,the tolerance of GmPM31-transgenic promotor A.thaliana to high temperature and high humidity increased.The activity of GUS increased,and they were expressed in the leaves,roots and flowers,and germination rate and vigor increased.[Conclusion]GmPM31 promoter improve the resistance of seeds to high temperature and high humidity stress and the ability to resist deterioration.关键词
