The era of reference genomes in conservation genomics
2022
Progress in genome sequencing now enables the large-scale generation of reference genomes. Various international initiatives aim to generate reference genomes representing global biodiversity. These genomes provide unique insights into genomic diversity and architecture, thereby enabling comprehensive analyses of population and functional genomics, and are expected to revolutionize conservation genomics.
Population dynamic of the extinct European aurochs: genetic evidence of a north-south differentiation pattern and no evidence of post-glacial expansi…
2010
International audience; Abstract Background The aurochs ( Bos primigenius ) was a large bovine that ranged over almost the entirety of the Eurasian continent and North Africa. It is the wild ancestor of the modern cattle ( Bos taurus ), and went extinct in 1627 probably as a consequence of human hunting and the progressive reduction of its habitat. To investigate in detail the genetic history of this species and to compare the population dynamics in different European areas, we analysed Bos primigenius remains from various sites across Italy. Results Fourteen samples provided ancient DNA fragments from the mitochondrial hypervariable region. Our data, jointly analysed with previously publis…
Genetic diversity within the R408W phenylketonuria mutation lineages in Europe
2003
The R408W phenylketonuria mutation in Europe has arisen by recurrent mutation in the human phenylalanine hydroxylase (PAH) locus and is associated with two major PAH haplotypes. R408W-2.3 exhibits a west-to-east cline of relative frequency reaching its maximum in the Balto–Slavic region, while R408W-1.8 exhibits an east-to-west cline peaking in Connacht, the most westerly province of Ireland. Spatial autocorrelation analysis has demonstrated that the R408W-2.3 cline, like that of R408W-1.8, is consistent with a pattern likely to have been established by human dispersal. Genetic diversity within wild-type and R408W chromosomes in Europe was assessed through variable number tandem repeat (VNT…
Conservation of the endangered Mediterranean tortoise Testudo hermanni hermanni: The contribution of population genetics and historical demography
2016
International audience; Estimating the genetic variation and demographic trends of species in decline is of major concern in conservation genetics. This study contributes to understanding how historical and anthropogenic factors shape the distribution of current genetic diversity in one of the most endangered reptiles in Western Europe, the Hermann's tortoise Testudo hermanni hermanni. We used 17 microsatellite loci, chosen from a pyrosequencing library specifically developed for the subspecies to genotype eight populations distributed over about 30 sample localities covering almost the entire geographic distribution of the sub-species. The population genetic results reflect a very strong g…
