The Prunus self-incompatibility locus (S locus) is seldom rearranged.
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 the exception of Prunus armeniaca S(2) hap...
متن کاملHistorical inferences from the self-incompatibility locus
Ancient polymorphism preserved at the self-incompatibility locus facilitates investigation of historical occurrences far older than extant species. We outline two ways in which studies of the S-locus can provide insights into patterns of speciation. First, we review evidence concerning the prevalence of founder events in speciation. A dramatic population size reduction is expected to reduce seq...
متن کاملSelf-incompatibility (S) locus region of the mutated S6-haplotype of sour cherry (Prunus cerasus) contains a functional pollen S allele and a non-functional pistil S allele.
This study characterizes the S6m-haplotype, a mutated S6-haplotype with an altered HindIII cut site, of sour cherry (Prunus cerasus). Inheritance and pollination studies of S-haplotypes from reciprocal crosses between 'Erdi Botermo' (EB; S4S6mSa) and 'Rheinische Schattenmorelle' (RS; S6SaSbSc) revealed that the S6m-haplotype conferred unilateral incompatibility with a non-functional pistil comp...
متن کاملRecombination at Prunus S-locus region SLFL1 gene.
In Prunus, the self-incompatibility (S-) locus region is <70 kb. Two genes--the S-RNase, which encodes the functional female recognition component, and the SFB gene, which encodes the pollen recognition component--must co-evolve as a genetic unit to maintain functional incompatibility. Therefore, recombination must be severely repressed at the S-locus. Levels of recombination at genes in the vi...
متن کاملRegulation of the S-Locus Receptor Kinase and Self-Incompatibility in Arabidopsis thaliana
Intraspecific 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 cysteine-rich protein (SCR). Arabidopsis thaliana is se...
