The identification of the Rosa S-locus and implications on the evolution of the Rosaceae gametophytic self-incompatibility systems. [PDF]

Sci Rep, 2021
In Rosaceae species, two gametophytic self-incompatibility (GSI) mechanisms are described, the Prunus self-recognition system and the Maleae (Malus/Pyrus/Sorbus) non-self- recognition system.

Gametophytic self-incompatibility in Andean capuli (Prunus serotina subsp. capuli): allelic diversity at the S-RNase locus influences normal pollen-tube formation during fertilization. [PDF]

PeerJ, 2020
Capuli (Prunus serotina subsp. capuli) is a tree species that is widely distributed in the northern Andes. In Prunus, fruit set and productivity appears to be limited by gametophytic self-incompatibility (GSI) which is controlled by the S-Locus.

Balancing selection and the crossing of fitness valleys in structured populations: diversification in the gametophytic self-incompatibility system

bioRxiv, 2021
The self-incompatibility locus (S-locus) of flowering plants displays a striking allelic diversity. How such a diversity has emerged remains unclear.

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 ...

Characterisation of the Gillenia S-locus provides insight into evolution of the nonself-recognition self-incompatibility system in apple [PDF]

Scientific Reports
Self-incompatibility (SI) in plants has evolved independently multiple times and S-RNase-based gametophytic self-incompatibility (GSI) is most common.

Lack of S-RNase-Based Gametophytic Self-Incompatibility in Orchids Suggests That This System Evolved after the Monocot-Eudicot Split. [PDF]

Front Plant Sci, 2017
Self-incompatibility (SI) is found in approximately 40% of flowering plant species and at least 100 families. Although orchids belong to the largest angiosperm family, only 10% of orchid species present SI and have gametophytic SI (GSI).

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

Evolution, 2018
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.

Molecular mechanism of the S-RNase-based gametophytic self-incompatibility in fruit trees of Rosaceae. [PDF]

Breed Sci, 2016
Self-incompatibility (SI) is a major obstacle for stable fruit production in fruit trees of Rosaceae. SI of Rosaceae is controlled by the S locus on which at least two genes, pistil S and pollen S, are located.

Molecular Research Progress on Gametophytic Self-Incompatibility in Rosaceae Species

Horticulturae
Self-incompatibility (SI) is a complex mechanism that prevents plants from self-fertilizing to preserve and promote genetic variability. The angiosperm species have developed two different SI systems, the sporophytic (SSI) and the gametophytic (GSI ...

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.
