During meiosis, crossover rates are not randomly distributed along the chromosome and their location may have a strong impact on functioning evolution of genome. To date, broad diversity recombination landscapes among plants has rarely been investigated formal comparative genomic approach is still needed to characterize assess determinants species chromosomes. We gathered genetic maps genomes for 57 flowering plant species, corresponding 665 chromosomes, which we estimated large-scale...
Age-related telomere shortening is considered a hallmark of the ageing process. However, recent cross-sectional study relative length (rTL) in bats failed to detect relationship between rTL and age long-lived genus Myotis (M. myotis M. bechsteinii), suggesting some other factors are responsible for driving dynamics these species. Here, we test if longitudinal data show signatures age-associated attrition differentiate which intrinsic or extrinsic likely drive dynamics. Using quantitative...
During the meiosis of many eukaryote species, crossovers tend to occur within narrow regions called recombination hotspots. In plants, it is generally thought that gene regulatory sequences, especially promoters and 5' 3' untranslated regions, are enriched in hotspots, but this has been characterized a handful species only. We also lack clear description fine-scale variation rates genic little known about hotspot position intensity plants. To address question, we constructed maps from...
Bacteria from the family Flavobacteriaceae often show low susceptibility to antibiotics. With exception of two Chryseobacterium spp. isolates that were positive for florfenicol resistance gene floR, no clinical genes identified by microarray in 36 salmonid fish could grow ≥ 4 mg/L florfenicol. Whole genome sequence analysis floR revealed presence a region contained antimicrobial tet(X) tetracycline gene, streptothricin and chloramphenicol acetyltransferase gene. In silico 377 published...
Abstract During meiosis, crossover rates are not randomly distributed along the chromosome and therefore they locally influence creation of novel genotypes efficacy selection. To date, broad diversity recombination landscapes among plants has rarely been investigated, undermining overall understanding constraints driving evolution frequency distribution. The determinants that shape local rate resulting species chromosomes still need to be assessed in a formal comparative genomic approach. We...
Dispersal influences population and evolutionary dynamics, in a manner that depends on by which dispersal strategies gene flow occurs. In some species, mating partners move exclusively for mating, dispersing genes but not individuals. This is the case many bat of lesser horseshoe (Rhinolophus hipposideros) shows genetic structure at fine spatial scale suggesting restricted dispersal. We investigated how natal shape this species two meta-populations using paternity assignments. Half inferred...
Abstract The study of phylogeography has transitioned from mitochondrial haplotypes to genome-wide analyses, blurring the line between this field and population genomics. Whole-genome sequencing offers opportunity join use both provides density markers necessary investigate genetic linkage recombination along genome. This facilitates unraveling complex demographic histories admixture divergent lineages, as is often case in species evolving recently deglaciated habitats. In study, we...
Abstract During the meiosis of many eukaryote species, crossovers tend to occur within narrow regions called recombination hotspots. In plants, it is generally thought that gene regulatory sequences, especially promoters and 5’-3’ untranslated regions, are enriched in hotspots, but this has been characterized a handful species only. We also lack clear description fine-scale variation rates genic little known about hotspot position intensity plants. To address question we constructed maps...
Invasive species are significant contributors to global changes and constitute a severe threat biodiversity. Yet invasions offer an incredible framework understand how small low-diverse introduced populations adapt novel environmental conditions succeed in colonizing large areas. However, due the insufficient data on origin of first propagule stage invasion, reconstructing species’ invasion history is challenging. Here, we applied genetic clustering methods explicit admixture tests combined...
