PHYLOGENOMIC ANALYSES OF ALL SPECIES OF SWORDTAIL FISHES (GENUS XIPHOPHORUS) SHOW THAT HYBRIDIZATION PRECEDED SPECIATION

Phylogenomic analyses of all species of swordtail fishes (genus Xiphophorus) show that hybridization preceded speciation

Abstract Hybridization has been recognized to play important roles in evolution, however studies of the genetic consequence are still lagging behind in vertebrates due Work Benches to the lack of appropriate experimental systems.Fish of the genus Xiphophorus are proposed to have evolved with multiple ancient and ongoing hybridization events.They ha

Modeling the efficiency of filovirus entry into cells in vitro: Effects of SNP mutations in the receptor molecule.

Interaction between filovirus glycoprotein (GP) and the Niemann-Pick C1 (NPC1) protein is essential for Front Panel Escutcheon membrane fusion during virus entry.Some single-nucleotide polymorphism (SNPs) in two surface-exposed loops of NPC1 are known to reduce viral infectivity.However, the dependence of differences in entry efficiency on SNPs rem
