Inferences on specificity recognition at the Malus×domestica gametophytic self-incompatibility system. [PDF]

Sci Rep, 2018
In Malus × domestica (Rosaceae) the product of each SFBB gene (the pollen component of the gametophytic self-incompatibility (GSI) system) of a S-haplotype (the combination of pistil and pollen genes that are linked) interacts with a sub-set of non-self ...

Protein Profiling of Pollen–Pistil Interactions in Almond (Prunus dulcis) and Identification of a Transcription Regulator Presumably Involved in Self-Incompatibility

Agronomy, 2022
The cultivated almond displays a gametophytic self-incompatibility system, which avoids self-fertilization, and it is controlled by a multi-allelic locus (S-locus) containing two genes specifically expressed in pistil (S-RNase) and pollen (SFB).

Intra- and inter-specific reproductive barriers in the tomato clade

Frontiers in Plant Science, 2023
Tomato (Solanum lycopersicum L.) domestication and later introduction into Europe resulted in a genetic bottleneck that reduced genetic variation.

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.

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

Evolution, 2018
Abstract Many 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 ...

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.

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).

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).

Self-incompatibility (S) genotypes of cultivated sweet cherries – An overview update 2020 [PDF]

, 2020
The fertility in sweet cherry is determined by a gametophytic self-incompatibility system, controlled by a multi-allelic S locus who prevents self-pollination.
