Incompatibility in angiosperms
WebJan 1, 2024 · The self-incompatibility (SI) system with the broadest taxonomic distribution in angiosperms is based on multiple S-locus F-box genes (SLFs) tightly linked to an S-RNase termed type-1. Multiple SLFs collaborate to detoxify nonself S-RNases while being unable to detoxify self S-RNases. WebIncompatibility in angiosperms is distinguished from other outbreeding mechanisms, but in fungi the distinction between separation of the sexes (dioecy) and incompatibility is a fine one. An incompatibility system is operating when all mating groups have the attributes and potentialities of both sexes. The most satisfactory method of ...
