Description:
Large segmental duplications cover much of the Arabidopsis thaliana genome. Little is known about their origins. We show that they are primarily due to at least four different large-scale duplication events that occurred 100 to 200 million years ago, a formative period in the diversification of the angiosperms. A better understanding of the complex structural history of angiosperm genomes is necessary to make full use of Arabidopsis as a genetic model for other plant species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vision, T J -- Brown, D G -- Tanksley, S D -- New York, N.Y. -- Science. 2000 Dec 15;290(5499):2114-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉USDA-ARS Center for Agricultural Bioinformatics, 604 Rhodes Hall, Cornell University, Ithaca, NY 14853, USA. tv23@cornell.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11118139" target="_blank"〉PubMed〈/a〉
