The advances of the studies on the molecular mechanism of rapeseed male sterility in three aspects of nuclear male sterility,cytoplasmic male sterility and the relations between organelle genome and cytoplasmic male sterility were reviewed.It was considered that rapeseed cytoplasmic male sterility was caused by the mosaic genes generated from the rearrangement of mitochondrial genes and was able to change the expressive pattern and function of their downstream genes,while rapeseed nuclear male sterility was caused the variati...
