Significats de directional selection en anglès

We find evidence of strong directional selection at this locus as evidenced by unusually high values of Fst.

This family exhibits the signatures of strong directional selection, with eleven positively selected positions in ligand-binding pockets of enzymes.

Additional advantageous variants in other homoelogs probably either contributed little benefit, or were unavailable in populations subjected to directional selection.

Oryza sativa-infecting isolates showed higher directional selection from host and subsequently tends to lower the genetic diversity in its genome.

Gene family contraction was detected for several components of the olfactory system, accompanied by instances of both directional selection and relaxation.

In contrast, skewed breeding values can displace the mean phenotype from the optimum, causing directional selection in the direction of the skew.

Multilocus surveys of sequence variation can be used to identify targets of directional selection, which are expected to have reduced levels of variation.

Stephanomys evolved in the context of directional selection related to the climatic trend of global cooling causing an increasing proportion of grasslands in southwestern Europe.

We separately performed genome-wide sequence analysis of 52 clinical isolates from 2008 to prospect for loci under recent directional selection.

Outlier loci were described on the basis of the geographic distribution of the T. urartu accessions, identifying a hotspot of directional selection on chromosome 4A.

Such climate-driven influence on the strength of directional selection acting on laying date could favour an adaptive response in this trait, since it is heritable.

Directional selection has acted on key cystatin active sites, suggesting that cystatins coevolve with their host target.
