Examination of S-Locus Regulated Differential Expression in Primula vulgaris Floral Development. [PDF]
Recent findings on the molecular basis of heteromorphic self-incompatibility in Primula have shown that the controlling self-incompatibility (S)-locus is not allelic, but is instead a small hemizygous region of only a few genes in the thrum genotype. How these genes alter the development of floral morphology and the specificity of self-incompatibility ...

The Prunus Self-Incompatibility Locus (S locus) Is Seldom Rearranged [PDF]
Self-incompatibility enables flowering plants to discriminate between self- and non-selfpollen. In Prunus, the 2 genes determining specificity are the S-RNase (the female determinant that is a glycoprotein with ribonuclease activity) and the SFB (the male determinant, a protein with an F-box motif). In all Prunus S haplotypes characterized so far, with

Regulation of the S-locus receptor kinase and self-incompatibility in Arabidopsis thaliana. [PDF]
AbstractIntraspecific mate selectivity often is enforced by self-incompatibility (SI), a barrier to self-pollination that inhibits productive pollen-pistil interactions. In the Brassicaceae, SI specificity is determined by two highly-polymorphic proteins: the stigmatic S-locus receptor kinase (SRK) and its pollen coat-localized ligand, the S-locus ...

Isolation of a second S-locus-related cDNA from Brassica oleracea: genetic relationships between the S locus and two related loci. [PDF]
Abstract Self-incompatibility in Brassica oleracea is controlled by the highly polymorphic S locus. Isolation and subsequent characterization of the S-locus-glycoprotein (SLG) gene, which encodes the S-locus-specific glycoprotein (SLSG), has revealed the presence of a self-incompatibility multigene family.

The effect of sheltered load on reproduction in Solanum carolinense, a species with variable self-incompatibility [PDF]
In previous studies, we have investigated the strength of self-incompatibility (SI) in Solanum carolinense, a highly successful weed with a fully functional SI system that inhabits early successional and other disturbed habitats.

Molecular characterization of DNA sequences from the Primula vulgaris S-locus [PDF]
Primula species provide possibly the best known examples of heteromorphic flower development and this breeding system has attracted considerable attention, including that of Charles Darwin. However, despite considerable recent advances in molecular genetics, nothing is known about the molecular basis of floral heteromorphy.

A nonS-locus F-box gene breaks self-incompatibility in diploid potatoes
Diploid potatoes are typically self-incompatible, complicating efforts to breed diploid cultivars. Here the authors report map-based cloning of the S-locus inhibitor (Sli) gene in potato which encodes a non S-locus F-box protein that is expressed in ...

Primula vulgaris (primrose) genome assembly, annotation and gene expression, with comparative genomics on the heterostyly supergene [PDF]
Primula vulgaris (primrose) exhibits heterostyly: plants produce self-incompatible pin- or thrum-form flowers, with anthers and stigma at reciprocal heights. Darwin concluded that this arrangement promotes insect-mediated cross-pollination; later studies

QTL analysis of heterostyly in Primula sieboldii and its application for morph identification in wild populations [PDF]
Background and Aims Primula sieboldii is a perennial clonal herb that is distributed around the Sea of Japan and is endangered in Japan. Its breeding system is characterized by heteromorphic self-incompatibility, and the morph ratio within a population ...
