Abstract

Flowering plant genomes lack flagellar and cytoplasmic dyneins as well as the proteins that make up the dynactin complex. The mechanisms for organizing the Golgi apparatus, establishing spindle poles, and moving nuclei, vesicles, and chromosomes in flowering plants must be fundamentally different from those in other systems where these processes are dependent upon dynein and dynactin.

摘要

开花植物的基因组缺乏鞭毛动力蛋白和细胞质动力蛋白，以及构成动力蛋白激活蛋白复合体的蛋白质。在开花植物中，组织高尔基体、建立纺锤极以及移动细胞核、囊泡和染色体的机制，必然与其他系统中的机制存在根本差异，在其他系统中，这些过程依赖于动力蛋白和动力蛋白激活蛋白复合体。
