We present a review of literature on the genetics of pollen-part mutations created in plants with a gametophytic self-incompatibility system. Plants carrying a pollen-part mutation produce pollen with an altered self-incompatibility response but have styles that display a normal response. Pollen-part mutants in the Fabaceae and Onagraceae have a simple loss-of-function mutation at the S locus and this is also believed to be true of pollen-part mutants from the Rosaceae. In the Solanaceae, pollen-part mutations are more complex and are frequently associated with a duplicated S allele. This suggests that pollen-part mutations, at least in the Solanaceae, can also result from gain-of-function mutations. Some solanaceous plants with a pollen-part mutation apparently lack duplicated S alleles suggesting that the mutant phenotypes arise from lesions at the S locus. These studies are discussed in the context of current self-incompatibility models. |
