摘要:

采用重复漂洗 离心法分离纯化了杜仲橡胶颗粒,SDS_PAGE分析发现杜仲橡胶颗粒含有十几种蛋白,其中以56ku、30ku 2种蛋白的丰度较高,分别称之为EuRPP56 和EuRPP30 。对杜仲雌雄株的比较表明,杜仲雌株叶片、雌株树皮及果皮中橡胶颗粒蛋白均是EuRPP30 含量高于EuRPP56 ,而雄株叶片、雄株树皮中正相反。进一步分离纯化了杜仲橡胶颗粒中丰度较高的30ku蛋白,并制备了该蛋白的抗体。免疫细胞化学分析结果表明,在叶片的含胶细胞中有阳性反应,而其它细胞无阳性反应。以上工作为研究杜仲胶粒结合蛋白功能以及阐明杜仲胶生物合成机制奠定基础

Abstract:

Rubber particles were isolated from Eucommia ulmoides by repeated centrifuging and washing. The results of SDS-PAGE analysis showed that more than 10 proteins associated with E. ulmoides rubber particles, among which 56 ku and 30 ku proteins were more in abundance, we named them EuRPP56 and EuRPP30. The expression of rubber particle proteins was not the same in male and female. In female EuRPP30 was more abundant than EuRPP56 , while in male, EuRPP56 was more abundant than EuRPP30. EuRPP30 was prepared and purified. We raised the antibody against EuRPP30. Immunofluorecent experiments showed that the gutta_containing cells could be stained. These works laid the foundation for studying the function of the rubber particle binding proteins as well as probing into the mechanism of E. ulmoides rubber biosynthesis.
