TI  - Genomic organization of the Papaver rhoeas self-incompatibility S(1) locus.
PG  - 131-9
AB  - The self-incompatibility (SI) response in Papaver rhoeas depends upon the cognate 
      interaction between a pollen-expressed receptor and a stigmatically expressed 
      ligand. The genes encoding these components are situated within the S-locus. In 
      order for SI to be maintained, the genes encoded by the S-locus must be 
      co-inherited with no recombination between them. Several hypotheses, including 
      sequence heterogeneity and chromosomal position, have been put forward to explain 
      the maintenance of the S-locus in the SI systems of the Brassicaceae and the 
      Solanaceae. A region of the Papaver rhoeas genome encompassing part of the 
      self-incompatibility S(1) locus has been cloned and sequenced. The clone contains 
      the gene encoding the stigmatic component of the response, but does not contain a 
      putative pollen S-gene. The sequence surrounding the S(1) gene contains several 
      diverse repetitive DNA elements. As such, the P. rhoeas S-locus bears 
      similarities to the S-loci of other SI systems. An attempt to localize the P. 
      rhoeas S-locus using fluorescence in situ hybridization (FISH) has also been 
      made. The potential relevance of the findings to mechanisms of recombination 
      suppression is discussed.
