However, there is no reason to sup- pose adaptive evolution along the human lineage has been confined to regions under purifying selection in most or all other species, particularly since such regions constitute a small fraction of the genome (Fig.

Analysis of functional variants in mitochondrial DNA of Finnish athletes

Adaptive mtDNA variants are less frequent in the population than the deleterious ones [18, 19], but animal studies have estimated that 26% of nonsynon- ymous substitutions are fixed by adaptive evolution [20].. Some of the rare nonsynonymous variants that were only harbored by endurance athletes (m.3308 T >. Previously, mtDNA mutations with high pathogenic potential have been detected in healthy human individuals in the 1000 Genomes Project and in individuals from the United Kingdom [24, 25].

Detecting fitness epistasis in recently admixed populations with genome-wide data

Comparison of chloroplast genomes of Gynura species: Sequence variation, genome rearrangement and divergence studies

tailieu.vn

The chloroplast genomes of angiosperms generally show slow substitution rates under adaptive evolution [12]. Considering its small size, conserved gene content and simple structure, the chloroplast genome is valid and cost-effective for studying phylogenetic relationships and the evolution of plants in different taxa. In the present study, we sequenced, assembled and an- notated the chloroplast genomes of four Gynura species..

Hecaton: Reliably detecting copy number variation in plant genomes using short read sequencing data

tailieu.vn

CNV comprises a large part of the genetic variation found within plant popu- lations and is thought to play a key role in adaptation and evolution [1]. One clear example of such adaptive evolution is presented by the weed species Amaran- thus palmeri, which rapidly became resistant to a widely used herbicide through amplification of the EPSPS gene, resulting in increased expression [2].
