For the analysis of LsGRP1 promoter expression profile, the activity assay of the GUS gene driven by LsGRP1 promoter will be detected in a agroinfiltration assay and in a Arabidopsis transformant. There are three aims in this year: (1) To measure the activity of LsGRP1 promoter in different tissues, organs and developmental stages. (2) To detect the stress responses of LsGRP1 promoter under the treatments of abiotic/biotic factors, signaling molecule and plant hormones. (3) To identify the expression level of LsGRP1 promoter in different kinds of plant species. This study will provide the information about the usage of LsGRP1 promoter in molecular breeding and plant disease control.啟動子病原誘導性單子葉植物分子育種promoterpathogen-induciblemonocotyledonmolecular breeding植物病原誘導性防禦基因啟動子特性分析及應用研究
