The gametophytic self-incompatibility locus has been thought to be a nonrecombining genomic region. Inferences have been made, however, about the functional importance of different parts of the S-locus, based on differences in the levels of variability along the gene, and this is valid only if recombination occurs. It is thus important to test whether recombination occurs within and near the S-locus. Several recent attempts to test this have reached conflicting conclusions. In this study, we examine a large data set on sequence variation at the S-locus in several species with gametophytic self-incompatibility systems, in the Solanaceae, Rosaceae and Scrophulariaceae. We use the longest sequences available to test for recombination based on linkage disequilibrium between polymorphic sites in the S-locus. The relationship between linkage disequilibrium and physical distance between the sites suggests rare intragenic exchange in the evolutionary history of four species of Solanaceae and two species of Rosaceae.
