Description:
Plant self-incompatibility (SI) systems are unique among self/nonself recognition systems in being based on the recognition of self rather than nonself. SI in crucifer species is controlled by highly polymorphic and co-evolving genes linked in a complex. Self recognition is based on allele-specific interactions between stigma receptors and pollen ligands that result in the arrest of pollen tube development. Commonalities and differences between SI and other self/nonself discrimination systems are discussed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nasrallah, June B -- New York, N.Y. -- Science. 2002 Apr 12;296(5566):305-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant Biology, Cornell University, Ithaca, NY 14853, USA. jbn2@cornell.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11951033" target="_blank"〉PubMed〈/a〉
