Description:
We report the cloning of Style2.1, the major quantitative trait locus responsible for a key floral attribute (style length) associated with the evolution of self-pollination in cultivated tomatoes. The gene encodes a putative transcription factor that regulates cell elongation in developing styles. The transition from cross-pollination to self-pollination was accompanied, not by a change in the STYLE2.1 protein, but rather by a mutation in the Style2.1 promoter that results in a down-regulation of Style2.1 expression during flower development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Kai-Yi -- Cong, Bin -- Wing, Rod -- Vrebalov, Julia -- Tanksley, Steven D -- New York, N.Y. -- Science. 2007 Oct 26;318(5850):643-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant Breeding and Genetics, Cornell University, Ithaca, NY 14853, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17962563" target="_blank"〉PubMed〈/a〉
