Web25 Apr 2016 · Self‐incompatibility (SI) is a complex trait that enforces outcrossing in plant populations. SI generally involves tight linkage of genes coding for the proteins that … Web1 Jun 2003 · Self-incompatibility (SI) is by far the most common of these, and is found in ca. 60% of flowering plants. SI is a genetically controlled pollen-pistil recognition system that provides a barrier to fertilization by self and self-related pollen in hermaphrodite (usually co-sexual) flowering plants.

http://faculty.agron.iastate.edu/madan/Gametophytic%20system.pdf WebSelf-compatibility ( SC) is the absence of genetic mechanisms which prevent self-fertilization resulting in plants that can reproduce successfully via both self-pollen and pollen from other individuals. Approximately one half of angiosperm species are SI, [1] the remainder being SC. tim hortons thickson

SI is controlled by genes at the S-locus. The S-LOCUS RECEPTOR KINASE ( SRK) gene encodes a serine/threonine kinase localized in the plasma membrane of the stigma epidermis ( Stein et al., 1996 ). tim hortons thessalon ontario
