Description:
A major challenge of biology is understanding the relationship between molecular genetic variation and variation in quantitative traits, including fitness. This relationship determines our ability to predict phenotypes from genotypes and to understand how evolutionary forces shape variation within and between species. Previous efforts to dissect the genotype-phenotype map were based on incomplete genotypic information. Here, we describe the Drosophila melanogaster Genetic Reference Panel (DGRP), a community resource for analysis of population genomics and quantitative traits. The DGRP consists of fully sequenced inbred lines derived from a natural population. Population genomic analyses reveal reduced polymorphism in centromeric autosomal regions and the X chromosome, evidence for positive and negative selection, and rapid evolution of the X chromosome. Many variants in novel genes, most at low frequency, are associated with quantitative traits and explain a large fraction of the phenotypic variance. The DGRP facilitates genotype-phenotype mapping using the power of Drosophila genetics.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3683990/" 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/PMC3683990/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mackay, Trudy F C -- Richards, Stephen -- Stone, Eric A -- Barbadilla, Antonio -- Ayroles, Julien F -- Zhu, Dianhui -- Casillas, Sonia -- Han, Yi -- Magwire, Michael M -- Cridland, Julie M -- Richardson, Mark F -- Anholt, Robert R H -- Barron, Maite -- Bess, Crystal -- Blankenburg, Kerstin Petra -- Carbone, Mary Anna -- Castellano, David -- Chaboub, Lesley -- Duncan, Laura -- Harris, Zeke -- Javaid, Mehwish -- Jayaseelan, Joy Christina -- Jhangiani, Shalini N -- Jordan, Katherine W -- Lara, Fremiet -- Lawrence, Faye -- Lee, Sandra L -- Librado, Pablo -- Linheiro, Raquel S -- Lyman, Richard F -- Mackey, Aaron J -- Munidasa, Mala -- Muzny, Donna Marie -- Nazareth, Lynne -- Newsham, Irene -- Perales, Lora -- Pu, Ling-Ling -- Qu, Carson -- Ramia, Miquel -- Reid, Jeffrey G -- Rollmann, Stephanie M -- Rozas, Julio -- Saada, Nehad -- Turlapati, Lavanya -- Worley, Kim C -- Wu, Yuan-Qing -- Yamamoto, Akihiko -- Zhu, Yiming -- Bergman, Casey M -- Thornton, Kevin R -- Mittelman, David -- Gibbs, Richard A -- GM 45146/GM/NIGMS NIH HHS/ -- R01 GM 059469/GM/NIGMS NIH HHS/ -- R01 GM 085183/GM/NIGMS NIH HHS/ -- R01 GM045146/GM/NIGMS NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- England -- Nature. 2012 Feb 8;482(7384):173-8. doi: 10.1038/nature10811.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, North Carolina State University, Raleigh, North Carolina 27695, USA. trudy_mackay@ncsu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22318601" target="_blank"〉PubMed〈/a〉
