Theoretical and Applied Genetics, 1993 Unilateral pollen-pistil incompatibility within the Brassicaceae has been re-examined in a series of interspecific and intergeneric crosses using 13 self-compatible (SC, Sc) species and 12 self-incompatible (SI) species from ten tribes.

Gametophytic Self-Incompatibility Reexamined
Science, 1983The 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

Stability of self-incompatibility systems
Theoretical and Applied Genetics, 1987Multi-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.

Self-incompatibility in flowering plants
Current Opinion in Genetics & Development, 1995Fertilization 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.

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.

Self-incompatibility in Antirrhinum
1992Self-incompatibility (SI) systems have been reported in almost half of the families of all flowering plants (de Nettancourt, 1977). Most commonly, SI is regulated by a single multiallelic locus, with the compatibility of the pollen with respect to the stigma being controlled by the haploid nucleus (East, 1940).

Publisher Summary This chapter discusses the self-incompatibility. Self-incompatibility is an elaborated breeding system for securing outcrossing and maximum recombination in the angiosperms. It is classified into heteromorphic and homomorphic types with respect to flower morphology.

Self-incompatibility (SI) has been widely investigated at both molecular and cellular levels in pear. This trait is controlled by a single multi-allelic locus encoding at least two components from the pollen and the pistil. The stylar-S determinant is an S-glycoprotein (S-RNase) that can inhibit pollen tube growth in a self-pistil, and induces a series

Self-incompatibility in the Commelinaceae
Annals of Botany, 1981This paper reports on a survey of self-incompatibility in 1 10 species of 22 genera in the family Commelinaceae. Genera from both tribes, Tradescantieae and Commelineae are included. Fifty-five species were found to be self-incompatible, 50 species self-compatible, and five species comprised individuals which were self-incompatible and individuals ...

Self-Incompatibility in the Grasses
2008The grasses are amongst the most important families of plants. The family includes major food crops and pastures and they dominate many natural ecosystems. Self-incompatibility (SI) is common in the grasses and is under the control of two unlinked loci, S and Z.
