Although it is known that in most angiosperms mitosis in early endosperm development is syncytial and synchronized, it is unclear how the synchronization is regulated. We showed previously that APC11, also named ZYGI, in Arabidopsis activates zygote division by interaction and degradation of cyclin B1. Here, we report that the mutation in APC11/ZYG1 led to unsynchronized mitosis and over-accumulation of cyclin B1-GUS in the endosperm. Mutations in two other APC subunits showed similar defects. Transgenic expression of stable cyclin B1 in the endosperm also caused unsynchronized mitosis. Further, downregulation of APC11 generated multi-nucleate somatic cells with unsynchronized mitotic division. Together, our results suggest that APC/C-mediated cyclin B1 degradation is critical for cell cycle synchronization.

As the starting point of a new life cycle,activation of the first division of the zygote is a critical event in both plants and animals. Due to poor accessibility of plant zygotes,it has remained poorly understood how this process is regulated. Through genetic analyses in Arabidopsis we identified a zygote-arrest 1(zyg1) mutant that exhibited zygote-lethality and over-accumulation of cyclin-GUS phenotypes. Map-based cloning showed that ZYG1 encodes the anaphase promoting complex/cyclosome(APC/C) subunit 11(APC11). live-cell imaging showed that APC11 is expressed in both egg and sperm cells,and that expression continued in zygotes and during early embryogenesis. Using an APC11-GFP fusion construct,we showed that APC11-GFP expression persisted throughout the mitotic cell cycle,and localized to cell plates during cytokinesis. Expression of non-degradable cyclin under the control of a zygote-specific DD45 promoter led to a zyg1-like zygote-lethal phenotype. Biochemical studies showed that APC11 is able to ubiquitinate cyclin,thus promoting cyclin degradation. These results together suggest that APC11-mediated cyclin degradation in Arabidopsis is critical for the first division of the zygote.

采用简单的液体模型,得到了容量因子k′与溶质溶剂的分子参数之间的理论关系。从这个理论方程可知不同表面积硅胶上的两种线性关系,即:不同溶质在不同表面积硅胶上k′值对数之间线性关系及溶质k′值的对数和表面积的对数之间线性关系。我们用不同表面积YWG-5微粒硅胶,用自制的高压液相色谱仪,以庚烷做冲洗剂,测定了芳烃卤代物、芳香醚、芳香酯等溶质的k′值。实验得到的线性关系与理论预测是一致的。
