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 کاملSLFL Genes Participate in the Ubiquitination and Degradation Reaction of S-RNase in Self-compatible Peach
It has been proved that the gametophytic self-incompatibility (GSI), mainly exists in Rosaceae and Solanaceae, is controlled by S genes, which are two tightly linked genes located at highly polymorphic S-locus: the S-RNase for pistil specificity and the F-box gene (SFB/SLF) for pollen specificity, respectively. However, the roles of those genes in SI of peach are still a subject of extensive de...

this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...
15 صفحه اولHistorical 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 کاملS-RNase-mediated self-incompatibility.
The Solanaceae, Rosaceae, and Scrophulariaceae families all possess an RNase-mediated self-incompatibility mechanism through which their pistils can recognize and reject self-pollen to prevent inbreeding. The highly polymorphic S-locus controls the self-incompatibility interaction, and the S-locus of the Solanaceae has been shown to be a multi-gene complex in excess of 1.3 Mb. To date, the func...
