WebAbstract As a major agent of rapid speciation, interspecific hybridization has played an important role in plant evolution. When hybridization involves species that exhibit self … WebSelf-incompatibility (SI) refers to all genetic mechanisms in flowering plants that prevent self-fertilization through the recognition and rejection of self-pollen by the style of a flower ( DeNettancourt, 1977 ). SI is generally classified into two types: heteromorphic and homomorphic SI.

WebSelf-incompatibility (SI) mechanisms prevent self-fertilization in flowering plants based on specific discrimination between self- and non-self pollen. Since this trait promotes outcrossing and avoids inbreeding it is a widespread mechanism of controlling sexual plant reproduction. Growers and breeders have effectively exploited SI as a tool for … WebThe crucifer family is particularly well suited for investigating the breakdown of SI in interspecific hybrid progenies of self-incompatible species, not only because of the prevalence of interspecific hybridization events in this family, but also because the crucifer SI system is well characterized. england ccc
