摘要：
Anther/pollen development is a highly programmed process in flowering plants. However, the molecular mechanism of regulating anther/pollen development is still largely unclear so far. Here, we report a cotton WRKY transcription factor (GhWRKY22) that functions in anther/pollen development. Quantitative RT-PCR and GUS activity analyses revealed that GhWRKY22 is predominantly expressed in the late developing anther/pollen of cotton. The transgenic Arabidopsis plants expressing GhWRKY22 displayed the male fertility defect with the fewer viable pollen grains. Expression of the genes involved in ja...
