Independent S-locus mutations caused self-fertility in Arabidopsis thaliana. [PDF]
PLoS Genetics, 2009 A common yet poorly understood evolutionary transition among flowering plants is a switch from outbreeding to an inbreeding mode of mating. The model plant Arabidopsis thaliana evolved to an inbreeding state through the loss of self-incompatibility, a ...

Segmental Translocation Contributed to the Origin of the Brassica S-locus
Horticultural Plant Journal, 2020 Self-incompatibility (SI), which has recurred during the evolution of plants, is one of the most important cross-pollination mating systems. Three S-loci have been reported in Brassicaceae, namely, Arabidopsis lyrata (Al), Brassica (Br), and ...

Genetic architecture and evolution of the S locus supergene in Primula vulgaris [PDF]
Nature Plants, 2016 Darwin’s studies on heterostyly in Primula described two floral morphs, pin and thrum, with reciprocal anther and stigma heights that promote insect-mediated cross-pollination.

Selecting an appropriate method for expressing S locus F-box-S2 recombinant protein
Biotechnology Reports, 2017 A single locus (S locus) including at least two linked genes (female and male determinants) genetically controls the gametophytic self-incompatibility (GSI) in apple, which has evolved to avoid self-fertilization.

Variation among S-locus haplotypes and among stylar RNases in almond. [PDF]
Sci Rep, 2020 AbstractIn many plant species, self-incompatibility systems limit self-pollination and mating among relatives. This helps maintain genetic diversity in natural populations but imposes constraints in agriculture and plant breeding. In almond [Prunus dulcis (Mill.) D.A.

Genetic Components of Self-Incompatibility in Brassica Vegetables
Horticulturae, 2023 Brassica vegetables are very important to human beings. Self-incompatibility (SI) is a common phenomenon in Brassica. Breeding by SI lines is an important way to utilize heterosis of Brassica vegetables. It is believed that the SI inheritance in Brassica

Secondary evolution of a self-incompatibility locus in the Brassicaceae genus Leavenworthia. [PDF]
PLoS Biology, 2013 Self-incompatibility (SI) is the flowering plant reproductive system in which self pollen tube growth is inhibited, thereby preventing self-fertilization. SI has evolved independently in several different flowering plant lineages.

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.

Origin of Allelic Diversity in Antirrhinum S Locus RNases [PDF]
The Plant Cell, 1996 In many plant species, self-incompatibility (SI) is genetically controlled by a single multiallelic S locus. Previous analysis of S alleles in the Solanaceae, in which S locus ribonucleases (S RNases) are responsible for stylar expression of SI, has demonstrated that allelic diversity predated speciation within this family.

Nature Communications, 2023 Breakdown of self-incompatibility has frequently been attributed to loss-of-function mutations of alleles at the locus responsible for recognition of self-pollen (i.e. the S-locus). However, other potential causes have rarely been tested.
