Description:
We sequenced and annotated the genome of the filamentous fungus Fusarium graminearum, a major pathogen of cultivated cereals. Very few repetitive sequences were detected, and the process of repeat-induced point mutation, in which duplicated sequences are subject to extensive mutation, may partially account for the reduced repeat content and apparent low number of paralogous (ancestrally duplicated) genes. A second strain of F. graminearum contained more than 10,000 single-nucleotide polymorphisms, which were frequently located near telomeres and within other discrete chromosomal segments. Many highly polymorphic regions contained sets of genes implicated in plant-fungus interactions and were unusually divergent, with higher rates of recombination. These regions of genome innovation may result from selection due to interactions of F. graminearum with its plant hosts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cuomo, Christina A -- Guldener, Ulrich -- Xu, Jin-Rong -- Trail, Frances -- Turgeon, B Gillian -- Di Pietro, Antonio -- Walton, Jonathan D -- Ma, Li-Jun -- Baker, Scott E -- Rep, Martijn -- Adam, Gerhard -- Antoniw, John -- Baldwin, Thomas -- Calvo, Sarah -- Chang, Yueh-Long -- Decaprio, David -- Gale, Liane R -- Gnerre, Sante -- Goswami, Rubella S -- Hammond-Kosack, Kim -- Harris, Linda J -- Hilburn, Karen -- Kennell, John C -- Kroken, Scott -- Magnuson, Jon K -- Mannhaupt, Gertrud -- Mauceli, Evan -- Mewes, Hans-Werner -- Mitterbauer, Rudolf -- Muehlbauer, Gary -- Munsterkotter, Martin -- Nelson, David -- O'donnell, Kerry -- Ouellet, Therese -- Qi, Weihong -- Quesneville, Hadi -- Roncero, M Isabel G -- Seong, Kye-Yong -- Tetko, Igor V -- Urban, Martin -- Waalwijk, Cees -- Ward, Todd J -- Yao, Jiqiang -- Birren, Bruce W -- Kistler, H Corby -- U54 HG003067/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2007 Sep 7;317(5843):1400-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Broad Institute of the Massachusetts Institute of Technology and Harvard, Cambridge, MA 02142, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17823352" target="_blank"〉PubMed〈/a〉
