Self-incompatibility (SI) is a general name for several genetic mechanisms in angiosperms, which prevent self-fertilization and thus encourage outcross and should not be confused with genetically controlled physical or temporal mechanisms that prevent self-pollination, such as heterostyly and sequential hermaphroditism (dichogamy).

Self-incompatibility (SI) is a genetic mechanism which prevents self-fertilisation via the recognition and rejection of self pollen. In the self-incompatible species Papaver rhoeas L., rejection of incompatible pollen is achieved through interaction of the female and male S-determinants, PrsS and PrpS, respectively.
These S RNases have been demonstrated to confer self-incompatibility through transformation experiments (Lee et al., ; Murfett et al., ). In Papaver, the stigmatic S gene encodes a small protein (Foote et al., ) that triggers a Ca 2+ -based signal transduction cascade resulting in the S -specific inhibition of incompatible pollen.

To date, the mechanism generating the allelic diversity of this gene is largely unknown. Natural populations offer a good opportunity to address this question because they likely contain different alleles that share Cited by: Introduction.
Self‐incompatibility (SI) is a genetic system that prevents self‐fertilization in many angiosperm species (East, ; Brewbaker, ).Evolutionary transitions from SI to self‐compatibility (SC) are thought to have occurred frequently (Stebbins, ; Igic et al., ).Theoretical investigations show that SC mutants that lack functional Cited by: 7.

Programmed cell death (or PCD) is the death of a cell in any form, mediated by an intracellular program, and is also referred to as Cellular Suicide. PCD is carried out in a biological process, which usually confers advantage during an organism's example, the differentiation of fingers and toes in a developing human embryo occurs because cells between the fingers.

The cytoskeleton is a key regulator of morphogenesis, sexual reproduction, and cellular responses to extracellular stimuli. Changes in the cellular architecture are often assumed to require actin-binding proteins as stimulus-response modulators, because many of these proteins are regulated directly by binding to intracellular second messengers or signaling .The population genetics of situations involving such interacting genes, where recombinants suffer reduced fitness, predicts that the invasion of the population by the second mutation will be affected by the recombination frequency between the two loci as well as its advantage in the presence of the first one (Charlesworth and Charlesworth b Cited by:
