Description:
Artemisinin is a plant natural product produced by Artemisia annua and the active ingredient in the most effective treatment for malaria. Efforts to eradicate malaria are increasing demand for an affordable, high-quality, robust supply of artemisinin. We performed deep sequencing on the transcriptome of A. annua to identify genes and markers for fast-track breeding. Extensive genetic variation enabled us to build a detailed genetic map with nine linkage groups. Replicated field trials resulted in a quantitative trait loci (QTL) map that accounts for a significant amount of the variation in key traits controlling artemisinin yield. Enrichment for positive QTLs in parents of new high-yielding hybrids confirms that the knowledge and tools to convert A. annua into a robust crop are now available.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Graham, Ian A -- Besser, Katrin -- Blumer, Susan -- Branigan, Caroline A -- Czechowski, Tomasz -- Elias, Luisa -- Guterman, Inna -- Harvey, David -- Isaac, Peter G -- Khan, Awais M -- Larson, Tony R -- Li, Yi -- Pawson, Tanya -- Penfield, Teresa -- Rae, Anne M -- Rathbone, Deborah A -- Reid, Sonja -- Ross, Joe -- Smallwood, Margaret F -- Segura, Vincent -- Townsend, Theresa -- Vyas, Darshna -- Winzer, Thilo -- Bowles, Dianna -- New York, N.Y. -- Science. 2010 Jan 15;327(5963):328-31. doi: 10.1126/science.1182612.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for Novel Agricultural Products, Department of Biology, University of York, York YO10 5YW, UK. iag1@york.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20075252" target="_blank"〉PubMed〈/a〉
