Incompatibility in plants
WebAbstract. Self-incompatibility systems in flowering plants have, over the last sixty years, been repeatedly compared and classified into a remarkably consistent plan which has stood the test of time. Probably the most constant part of the plan has been the genetic control of the pollen into two distinct classes: Gametophytic, with the S gene ... WebAdaptation to local conditions likely plays an important role in plant diversity and speciation. A fuller understanding of the role of adaptation in speciation requires connecting particular molecular events with selection occurring at individual, population, or community levels. Here I discuss five areas in which we understand the molecular basis of adaptation and …

WebSelf-incompatibility 992 is found in various plants, but is most extensively studied in Brassica plants. The S multiple allele system determines self-incompatibility of Brassicaceae plants; incompatibility occurs when the phenotype of the pollen S gene matches that of the stigma S gene.
WebSelf-incompatibility in plants. Self-incompatibility (SI) is a general name for several genetic mechanisms in angiosperms, which prevent self-fertilization and thus encourage outcrossing.In plants with SI, when a pollen grain produced in a plant reaches a stigma of the same plant or another plant with a similar genotype, the process of pollen …
