人类辅助基因流动有助于基因抢救。小种群近亲繁殖率高会降低多样性,降低体能,增加灭绝风险。通过人类干扰引入不相关的个人或生物体可以减少近亲繁殖的程度,改善多样性,从而提高整体健康。 Tags Gene FlowGenetic VariationPopulationTransfer Of Genetic VariantsOrganismsGametesPlant PollenAnimalsNovel Genetic VariantsGene Freq...
Gene flow is an integral element in the evolutionary biology of plant species. Gene flow promotes genetic variability, allows gene migration, and can enable more rapid evolutionary dynamics (Ehrlich and Raven, 1969; Mallory-Smith et al., 2015). Defined as the movement of genes by gametes, dias...
Gene flowSouth AsiaSoutheast AsiaVolant vertebratesGene flow, the exchange of genetic material between populations is an important biological process, which shapes and maintains biodiversity. The successful movement of individuals between populations depends on multiple factors determined by species biology ...
Chlamydiae is a bacterial phylum composed of obligate animal and protist endosymbionts. However, other members of the Planctomycetes–Verrucomicrobia–Chlamydiae superphylum are primarily free living. How Chlamydiae transitioned to an endosymbiotic lifes
Recent advances in sequencing and fluorescence microscopy now allow scientists to probe gene expression at the basic unit of information flow — the single cell. From a systems biology viewpoint, the methods of single-cell imaging and single-cell RNA sequencing (scRNA-seq) hold tremendous promise ...
host adaptation or other types of local adaptation as consequences of reduction of gene flow promoting genetic drift and natural selection1. For example, the causal agent of the white-nose syndrome in bats, the killer of millions of bats in North America since its discovery in 2006, was shown...

One well-studied example involves reduced gene flow associated withinversionevents on whole chromosomes in the North AmericanDrosophilaspeciesD. pseudoobscuraandD. persimilis. These co-occurring species are less than 1 million years diverged and differ by...
Horizontal Gene Transfer (HGT) is beneficial to a cell if the acquired gene confers a useful function, but is detrimental if the gene has no function, if it is incompatible with existing genes, or if it is a selfishly replicating mobile element. If the b
Genetic diversity, genetic structure, and gene flow in plant populations and their influencing factors are important in conservation biology. Cypripedium macranthos is one of the few wild orchids with high ornamental value in northern China. However, over the past decade, excessive collection, trading...
