The distribution of unilateral cross-incompatibility in Solanum seems to parallel that of self-incompatibility. The widespread occurrence of self-incompatibility (SI) in angiosperms is outlined by Nettancourt (1977).

WebJan 3, 2024 · Some species of angiosperms can avoid self-fertilization through self-incompatibility (Bateman 1952). In plants with self-incompatibility, the process by which the sperm meets the egg is interrupted at some stage if pollen grains have a genotype that is the same as the parent (e.g. Schopfer et al. 1999). This prevents selfing – and also ...

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.
