水稻 CesA4 基因启动子与 GUS 基因融合表达

Objective: To study the localization of rice CesA4 gene in rice tissues and organs fusing with GUS reporter gene. Methods: The rice CesA4 promoter was cloned. The expressions of the rice CesA4 gene promoters and the GUS gene were detected by GUS staining.Results: The cloning of rice CesA4 promoter gene was successful. It was found that the rice CesA4 gene expressed in rice fibers of roots, stems, leaves, sheath and spike. Conclusion: It is a simple and effective way that rice CesA4 gene expression in rice was located by the fusion the gene promoter and the GUS gene.
