Self-incompatibility: How to Stay Incompatible
نویسنده
چکیده
Plant self-incompatibility is controlled by different genes for the recognition reactions of pollen and stigmas, yet correct association of the two genes have been maintained in two Brassica species.

Discrimination and preliminary selection of self-compatible progenies among controlled crosses in almond using Sf specific primer
Self-incompatibility in almond and Prunus species is an important trait that prevents self-fertilization. Selfincompatibility in almond is controlled gametophytically by the multiallelic S-locus. Present study was done in order to identification and preliminary selection of self compatible progenies resulted from controlled crosses in almond using specific primer SfF/SfR. Some important morphol...
متن کاملInfuence of pollen source and pollination Time on Furit set of Ferragness Self-incompatibility Almond
Different experiments have showed that interruption in pollination is an important problem in most almond orchards.Asmost of the almond cultivars are self-incompatible,pollination cannot be performed desirably and as a result a failure in almond yield is occurred.Thus under this circumstance,determination of selective cultivars compatibility and choosing appropriate pollinizers are so important...
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...

A M O N G the mechanisms restricting the flow of genes between discrete populations of plants, unilateral incompatibility (UI) is unique in that one of the reciprocal crossing combinations succeeds whereas the other fails. The term unilateral incompatibility is generally restricted to a phenomenon thought to be closely related to self-incompatibility (SI), for it occurs in matings of self-ferti...
