Description:
Plants with a winter growth habit flower earlier when exposed for several weeks to cold temperatures, a process called vernalization. We report here the positional cloning of the wheat vernalization gene VRN2, a dominant repressor of flowering that is down-regulated by vernalization. Loss of function of VRN2, whether by natural mutations or deletions, resulted in spring lines, which do not require vernalization to flower. Reduction of the RNA level of VRN2 by RNA interference accelerated the flowering time of transgenic winter-wheat plants by more than a month.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4737501/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4737501/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yan, Liuling -- Loukoianov, Artem -- Blechl, Ann -- Tranquilli, Gabriela -- Ramakrishna, Wusirika -- SanMiguel, Phillip -- Bennetzen, Jeffrey L -- Echenique, Viviana -- Dubcovsky, Jorge -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2004 Mar 12;303(5664):1640-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Agronomy and Range Science, University of California, Davis, CA 95616, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15016992" target="_blank"〉PubMed〈/a〉
