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 ...
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
such as whole chromosomes or chromosomal regions. 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...
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 ...
2g). For example, GNPDA1 was an eGene in TCM, but not in TEM or in whole memory cells (Fig. 2g). These genes were only detected as eQTLs in specific cell clusters, and we observed that many were not detected in the Database of Immune Cell eQTLs (DICE) data set, which includes ...
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
In cell biology, morpholinos are used to understand early developmental processes. Cilia-generated fluid flow in Kupffer's vesicle is one example, which controls left-right patterning in zebrafish. Fluid flow runs counterclockwise in control-injected embryos, whereas silencing of a gene that regulates...
In the past 40 years, there has been increasing acceptance that variation in levels of gene expression represents a major source of evolutionary novelty. Gene expression divergence is therefore likely to be involved in the emergence of incipient species,
