Gametophytic Self-Incompatibility Reexamined

Science, 1983
The conventional hypothesis of gametophytic self-incompatibility in the angiosperms involves one to four multiallelic incompatibility loci and the positive inhibition of incompatible pollen tubes. However, this concept does not accommodate recent experimental data indicating that there may be many loci. An alternative hypothesis which incorporates many

SELF-INCOMPATIBILITY IN PLANTS

Annual Review of Plant Biology, 2005
Sexual reproduction in many flowering plants involves self-incompatibility ( SI self-incompatibility ), which is one of the most important systems to prevent inbreeding. In many species, the self-/nonself-recognition of SI is controlled by a single polymorphic locus, the S-locus.

Species Selection Maintains Self-Incompatibility

Science, 2010
Incompatible Self-Compatibility Macroevolutionary processes driving species differences in diversification rates are important in explaining the variation we see in nature, but the extent of this process and how much the traits within a single species can drive changes in the diversification rate are unknown.

Self-incompatibility in flowering plants

Current Opinion in Genetics & Development, 1995
Fertilization in flowering plants begins with a pollen grain bearing the male gametes landing on the female stigma. Several mechanisms enable the stigma to discriminate between the different types of pollen that it may receive, of which the best studied is self-incompatibility.

Stability of self-incompatibility systems

Theoretical and Applied Genetics, 1987
Multi-locus self-incompatibility systems offer few obvious adaptive advantages to the species possessing them. However, the gametophytic system's independent gene action allows the separate genes in a two gene system to behave as if they were individually not involved in a systematic disruption of panmixia.

Quantitatively determined self-incompatibility

Theoretical and Applied Genetics, 1989
It has been reported that incomplete self-incompatibility could be determined in Borago officinalis by many genes. Simple ten-gene models for such enforced cross-fertilization have been developed and their properties examined by computer simulation.

Self-incompatibility inRibes

Euphytica, 1970
Seven species ofRibes were studied; all of them proved to be self-incompatible. They were found to have hollow styles and incompatible pollen tubes were not inhibited until they reached the ovary. The extent to which self-pollen tubes penetrated the ovary before being arrested varied with different species.

Genetic regulation of self‐incompatibility

Critical Reviews in Plant Sciences, 1993
Abstract Self‐incompatibility is a cell‐cell recognition system in higher plants that is based on the ability of the pistil to discriminate “self‐pollen from “non‐self"‐pollen. In the simplest systems, this recognition response is controlled by a single locus — the S‐locus — with multiple alleles. Pollination of a pistil with pollen bearing an S‐allele
