摘要：

The first mitotic division of the haploid microspore in the pathway of pollen development is a striking example of an asymmetric division that leads to different fates in the daughter cells. Recently, new insight into microspore polarity and cell-fate determination in pollen has been obtained in Arabidopsis by applying cell-fate markers in conjunction with a mutational approach. These studies suggest that development into a vegetative cell is the default programme, but that this is repressed in the generative cell as a result of division asymmetry. Gametophytic mutants that affect cell division, division asymmetry and cell fate have highlighted the importance of asymmetrically localized factors in microspore polarity and cell-fate determination in pollen.
