Origin and spread of mitochondrial DNA haplogroup U7
Sahakyan, H; Kashani, BH; Tamang, R; Kushniarevich, A; Francis, A; Costa, MD; Pathak, AK; Khachatryan, Z; Sharma, I; van Oven, M; Parik, JHuman mitochondrial DNA haplogroup U is among the initial maternal founders in Southwest Asia and Europe and one that best indicates matrilineal genetic continuity between late Pleistocene huntergatherer groups and present-day populations of Europe. While most haplogroup U subclades are older than 30 thousand years, the comparatively recent coalescence time of the extant variation of haplogroup U7 (~16–19 thous...
A substantial prehistoric European ancestry amongst Ashkenazi maternal lineages
Costa, MD; Pereira, JB; Pala, M; Fernandes, V; Olivieri, A; Achilli, A; Perego, UA; Rychkov, S; Naumova, O; Hatina, J; Woodward, SR; Eng, KKThe origins of Ashkenazi Jews remain highly controversial. Like Judaism, mitochondrial DNA is passed along the maternal line. Its variation in the Ashkenazim is highly distinctive, with four major and numerous minor founders. However, due to their rarity in the general population, these founders have been difficult to trace to a source. Here we show that all four major founders, ~40% of Ashkenazi mtDNA variatio...
Mitochondrial DNA signals of Late Glacial recolonization of Europe from Near Ea...
Pala, M; Olivieri, A; Achilli, A; Accetturo, M; Metspalu, E; Reidla, M; Tamm, E; Karmin, M; Reisberg, T; Hooshiar Kashani, B; Perego, UA; Carossa, VHuman populations, along with those of many other species, are thought to have contracted into a number of refuge areas at the height of the last Ice Age. European populations are believed to be, to a large extent, the descendants of the inhabitants of these refugia, and some extant mtDNA lineages can be traced to refugia in Franco-Cantabria (haplogroups H1, H3, V, and U5b1), the Italian Peninsula (U5b3), and t...
Mitochondrial genomes from modern horses reveal the major haplogroups that unde...
Achilli, A; Olivieri, A; Soares, P; Lancioni, H; Kashani, BH; Perego, UA; Nergadze, SG; Carossa, V; Santagostino, M; Capomaccio, S; Felicetti, MArchaeological and genetic evidence concerning the time and mode of wild horse (Equus ferus) domestication is still debated. High levels of genetic diversity in horse mtDNA have been detected when analyzing the control region; recurrent mutations, however, tend to blur the structure of the phylogenetic tree. Here, we brought the horse mtDNA phylogeny to the highest level of molecular resolution by analyzing 83 ...
