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 ...
Mutation ‘C11994T’ in the mitochondrial ND4 gene is not a cause of low sperm mo...
Pereira, L; Gonçalves, J; Bandelt, H-JIt has recently been suggested that a hitherto unobserved mutation, C11994T, causes oligoasthenozoospermia in men from India but at the same time does not affect systems other than the motility of the sperm. There are good reasons to question this proposition, in view of the worldwide mtDNA database and the Indian record in particular. We have further analyzed the oligoasthenozoospermic samples from a previous ...
Mitochondrial portrait of the Cabo Verde archipelago: the Senegambian outpost o...
Brehm, A; Pereira, L; Bandelt, H-J; Prata, MJ; Amorim, AIn order to study the matrilineal genetic composition in Cabo Verde (Republic of Cape Verde), an archipelago that used to serve as a Portuguese entrepôt of the Atlantic slave trade, we have analysed a total of 292 mtDNAs sampled from the seven inhabited islands for the hypervariable segment I (HVS-I) and some characteristic RFLPs of the coding regions. The different settlement history of the northwestern group ...
Phylogeography of the human mitochondrial haplogroup L3e: a snapshot of African...
Bandelt, H-J; Alves-Silva, J; Guimarães, PEM; Santos, MS; Brehm, A; Pereira, L; Coppa, A; Larruga, JM; Rengo, C; Scozzari, R; Torroni, A; Prata, MJThe mtDNA haplogroup L3e, which is identified by the restriction site +2349 MboI within the Afro-Eurasian superhaplogroup L3 (-3592 HpaI), is omnipresent in Africa but virtually absent in Eurasia (except for neighbouring areas with limited genetic exchange). L3e was hitherto poorly characterised in terms of HVS-I motifs, as the ancestral HVS-I type of L3e cannot be distinguished from the putative HVS-I ancestor...
