Description:
Mountain gorillas are an endangered great ape subspecies and a prominent focus for conservation, yet we know little about their genomic diversity and evolutionary past. We sequenced whole genomes from multiple wild individuals and compared the genomes of all four Gorilla subspecies. We found that the two eastern subspecies have experienced a prolonged population decline over the past 100,000 years, resulting in very low genetic diversity and an increased overall burden of deleterious variation. A further recent decline in the mountain gorilla population has led to extensive inbreeding, such that individuals are typically homozygous at 34% of their sequence, leading to the purging of severely deleterious recessive mutations from the population. We discuss the causes of their decline and the consequences for their future survival.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4668944/" 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/PMC4668944/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xue, Yali -- Prado-Martinez, Javier -- Sudmant, Peter H -- Narasimhan, Vagheesh -- Ayub, Qasim -- Szpak, Michal -- Frandsen, Peter -- Chen, Yuan -- Yngvadottir, Bryndis -- Cooper, David N -- de Manuel, Marc -- Hernandez-Rodriguez, Jessica -- Lobon, Irene -- Siegismund, Hans R -- Pagani, Luca -- Quail, Michael A -- Hvilsom, Christina -- Mudakikwa, Antoine -- Eichler, Evan E -- Cranfield, Michael R -- Marques-Bonet, Tomas -- Tyler-Smith, Chris -- Scally, Aylwyn -- 098051/Wellcome Trust/United Kingdom -- 099769/Z/12/Z/Wellcome Trust/United Kingdom -- 260372/European Research Council/International -- HG002385/HG/NHGRI NIH HHS/ -- R01 HG002385/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Apr 10;348(6231):242-5. doi: 10.1126/science.aaa3952.
