Confirmation of a Gametophytic Self-Incompatibility in Oryza longistaminata [PDF]
Oryza longistaminata, a wild species of African origin, has been reported to exhibit self-incompatibility (SI). However, the genetic pattern of its SI remained unknown.

The different mechanisms of gametophytic self–incompatibility [PDF]
Self–incompatibility (SI) involves the recognition and rejection of self or genetically identical pollen. Gametophytic SI is probably the most widespread of the SI systems and, so far, two completely different SI mechanisms, which appear to have evolved separately, have been identified.

Convergent evolution at the gametophytic self-incompatibility system in Malus and Prunus. [PDF]
S-RNase-based gametophytic self-incompatibility (GSI) has evolved once before the split of the Asteridae and Rosidae. This conclusion is based on the phylogenetic history of the S-RNase that determines pistil specificity.

PLC-Mediated Signaling Pathway in Pollen Tubes Regulates the Gametophytic Self-incompatibility of Pyrus Species [PDF]
Among the Rosaceae species, the gametophytic self-incompatibility (GSI) is controlled by a single multi-allelic S locus, which is composed of the pistil-S and pollen-S genes.

LOSS OF GAMETOPHYTIC SELF-INCOMPATIBILITY WITH EVOLUTION OF INBREEDING DEPRESSION [PDF]
Gametophytic self-incompatibility (SI) in plants is a widespread mechanism preventing self-fertilization and the ensuing inbreeding depression, but it often evolves to self-compatibility. We analyze genetic mechanisms for the breakdown of gametophytic SI, incorporating a dynamic model for the evolution of inbreeding depression allowing for partial ...

Cytoskeleton, Transglutaminase and Gametophytic Self-Incompatibility in the Malinae (Rosaceae). [PDF]
Self-incompatibility (SI) is a complex process, one out of several mechanisms that prevent plants from self-fertilizing to maintain and increase the genetic variability. This process leads to the rejection of the male gametophyte and requires the co-participation of numerous molecules.

A Novel Multivariate Approach to Phenotyping and Association Mapping of Multi-Locus Gametophytic Self-Incompatibility Reveals S, Z, and Other Loci in a Perennial Ryegrass (Poaceae) Population [PDF]
Self-incompatibility (SI) is a mechanism that many flowering plants employ to prevent fertilisation by self- and self-like pollen ensuring heterozygosity and hybrid vigour.

Predicting Specificities Under the Non-self Gametophytic Self-Incompatibility Recognition Model [PDF]
Non-self gametophytic self-incompatibility (GSI) recognition system is characterized by the presence of multiple F-box genes tandemly located in the S-locus, that regulate pollen specificity.

Gametophytic Self-Incompatibility Systems. [PDF]
is one of the mechanisms that have evolved to encourage outbreeding in flowering plants and is defined as “the inability of a fertile hermaphrodite seed plant to produce zygotes after self-pollination” (de Nettancourt, 1977). The effectiveness of SI in promoting outbreeding is believed to be one of the most important factors that ensured the evolu ...
