S-RNase Evolution in Self-Incompatibility: Phylogenomic Insights into Synteny with Class I T2 RNase Genes.

Plant Physiology
S-RNases are essential in the gametophytic self-incompatibility (GSI) system of many flowering plants, where they act as stylar-S determinants. Despite their prominence, the syntenic genomic origin and evolutionary trajectory of S-RNase genes in eudicots

Gametophytic self-incompatibility in eudicots

2017
The S-RNase based gametophytic self-incompatibility (GSI) system is a genetic mechanism present in Solanaceae, Plantaginaceae, Rosaceae, and Rubiaceae, that prevents self-fertilization. This system emerged before the split between Asteridae and Rosidae, about 120 million years ago (MYa), and thus, it is expected to be present in many self-incompatible (

A gene action model to explain gametophytic self-incompatibility

Euphytica, 1966
Gametophytic self-incompatibility in flowering plants can be explained in terms of recent concepts of gene action. The S alleles may be assumed to be regulators which produce monomers of a dimer repressor controlling a high rate of growth operon in the pollen tube.

Molecular Genetics of Gametophytic Self-incompatibility in Solanaceae

1992
Self-incompatibility exhibited by members of the Solanaceae family is of gametophytic type and, in the simplest case, is controlled by a single multiallelic locus called the S-locus. (For a comprehensive treatise on the self-incompatibility system refer to the monograph by de Nettancourt, 1977.) Fertilization is blocked when the S-allele carried by the

Molecular genetics of gametophytic self-incompatibility in Petunia hybrida

1994
The most famous, if not necessarily the first, description of gametophytic self-incompatibility in Petunia was given by Charles Darwin (1876), who noted: ... for protected flowers, with their own pollen placed on the stigma, never yielded nearly a full complement of seed; whilst those left uncovered produced fine capsules, showing that pollen from ...

[Progress in study on signal transduction of gametophytic self-incompatibility].

Yi chuan = Hereditas, 2008
In nature, most self-incompatible flowering plants (angiosperms) show gametophytic self-incompatibility. Although gametophytic self-incompatibility functions can ultimately prevent self-fertilization, flowering plants have adopted different signal transduction pathways to reject self pollen.
