Web1 day ago · Self-incompatibility (SI) systems are non-homologous molecular mechanisms that prevent inbreeding and promote outcrossing in flowering plants. 44 Three of the domains associated with maximum height in angiosperms are components of the most well-characterized SI system (e.g., Figure 5 B, “PF00954 – S-locus glycoprotein domain”). Webdegree, secondary self-incompatibility, have subsequently arisen in certain members of these predominantly self-compatible groups. 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).
