The different mechanisms of gametophytic self-incompatibility. [PDF]

Philos Trans R Soc Lond B Biol Sci, 2003
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.

Segregation Distortion for Male Parents in High Density Genetic Maps from Reciprocal Crosses between Two Self-Incompatible Cultivars Confirms a Gametophytic System for Self-Incompatibility in Citrus

Agriculture, 2021
Self-incompatibility is an important evolutionary feature in angiosperms and has major implications for breeding strategies in horticultural crops.

The evolutionary history of plant T2/S-type ribonucleases [PDF]

PeerJ, 2017
A growing number of T2/S-RNases are being discovered in plant genomes. Members of this protein family have a variety of known functions, but the vast majority are still uncharacterized.

Expression of self-incompatibility in Coffea canephora genotypes grown in the western Amazon

Pesquisa Agropecuária Brasileira, 2022
The objective of this work was to characterize the expression of gametophytic self-incompatibility in a Coffea canephora breeding population, to assist in the management and development of new cultivars.

Different Flowering Strategies Ensure Reproductive Success in Two Coexisting Self-Incompatible Orchids. [PDF]

Ecol Evol
This study compares the reproductive strategies of two self‐incompatible orchids, Pholidota articulata (mass‐flowering) and Coelogyne prolifera (steady‐state flowering). Despite differences in pollinator visitation and pollinia transfer efficiency—higher in P. articulata—both species achieved similar natural fruit set rates over 3 years.

Bud pollination and other techniques are ineffective in breaking late-acting self-incompatibility in Ceiba chodatii (Malvaceae - Bombacoideae)

Acta Botânica Brasílica, 2021
There are two homomorphic self-incompatibility (SI) mechanisms among flowering plants - gametophytic self-incompatibility (GSI) and sporophytic self-incompatibility (SSI).

Breakdown of gametophytic self‐incompatibility in subdivided populations [PDF]

Evolution, 2018
AbstractMany hermaphroditic flowering plants species possess a genetic self-incompatibility (SI) system that prevents self-fertilization and is typically controlled by a single multiallelic locus, the S-locus. The conditions under which SI can be stably maintained in single isolated populations are well known and depend chiefly on the level of ...

Toward in vitro fertilization in Brachiaria spp. [PDF]

, 2010
Brachiaria are forage grasses widely cultivated in tropical areas. In vitro pollination was applied to accessions of Brachiaria spp. by placing pollen of non-dehiscent anthers on a solid medium near isolated ovaries.

Fruit Quality Traits and Self- (In)compatibility Allele Status of Some Apricot (<i>Prunus armeniaca</i> L.) Seedlings Obtained by Cross-Breeding. [PDF]

Food Sci Nutr
Hybrid genotypes 6, 3, 8, and 39 having high fruit weight, an important character in table apricots, and hybrid genotypes 34, 35, 47, and 68 having high SSC, an important feature in dried apricots, were determined to be self‐compatible. Although hybrid genotype 3 was self‐incompatible, it attracted attention with its red fruit color and weight.

Two Self-Incompatibility Sites Occur Simultaneously in the Same Acianthera Species (Orchidaceae, Pleurothallidinae)

Plants, 2020
In most species of Pleurothallidinae, the self-incompatibility site occurs in the stylar canal inside the column, which is typical of gametophytic self-incompatibility (GSI).
