摘要: 为了探讨花椰菜细胞质雄性不育机理,利用比较蛋白质组学研究技术,对花椰菜细胞质雄性不育系(CMS)、保持系花粉母细胞减数分裂期、双-三核期及花粉粒时期的蛋白质组差异作了比较,发现CMS在花粉败育期(双-三核期)蛋白质组呈现明显变化,CMS中有4个蛋白质斑点(斑点1,9,19,20)缺失,有7个蛋白质斑点(斑点4,6,7,8,15,17,18)表达量明显减少,有10个蛋白质斑点(斑点2,3,5,10,11,12,13,14,16,21)表达量增加。差异蛋白斑点的质谱分析表明,CMS中的差异蛋白其功能涉及信号转导、能量代谢、蛋白质合成、光合作用与植物的防御与抗性等。该研究结果对于花椰菜不育机理探讨及保持系的选择均有一定参考意义。

Abstract: In order to investigate the mechanism of cytoplasmic male sterility in Cauliflower,we analyzed the proteomic altered with pollen mother cells(PMC) at different developmental stages(meiosis stage of PMC,double-three nucleus stage and pollen grain stage) of cytoplasmic male sterility line(CMS) and corresponding maintainer line in cauliflowers. The results showed that proteomic altered was observed in CMS compared with maintainer line,especially in double-three nucleus stage. 4 protein spots(spot 1,9,19,20) were lost and 7 protein spots were showed decreased and 10 protein spots were increased in protein abundance in CMS,respectively,10 protein spots were identified using MS/MS and NCBI database searching. The results demonstrated that these proteins were involved in a wide range of signal transduction,energy metabolism,protein biosynthesis,photosynthesis and resistance reaction. These experimental results may be used in male sterility mechanism investigation and maintainer line selection in cauliflowers.
