Joint assembly and genetic mapping of the Atlantic horseshoe crab genome reveals ancient whole genome duplication [PDF]
, 2013 Horseshoe crabs are marine arthropods with a fossil record extending back approximately 450 million years. They exhibit remarkable morphological stability over their long evolutionary history, retaining a number of ancestral arthropod traits, and are ...

Constraining Whole-Genome Duplication Events in Geological Time
, 2023 The timing of whole-genome duplication (WGD) events is crucial to understanding their role in evolution and underpins many hypotheses linking WGD to increased diversity and complexity. As such, means of estimating the timing of the WGD events relative to their macroevolutionary outcomes are of considerable importance. Molecular clock methods facilitate

A model for biased fractionation after whole genome duplication [PDF]
BMC Genomics, 2012 Paralog reduction, the loss of duplicate genes after whole genome duplication (WGD) is a pervasive process. Whether this loss proceeds gene by gene or through deletion of multi-gene DNA segments is controversial, as is the question of fractionation bias, namely whether one homeologous chromosome is more vulnerable to gene deletion than the other.As a ...

Molecular cytogenetic differentiation of paralogs of Hox paralogs in duplicated and re-diploidized genome of the North American paddlefish (Polyodon spathula). [PDF]
, 2017 BackgroundAcipenseriformes is a basal lineage of ray-finned fishes and comprise 27 extant species of sturgeons and paddlefishes. They are characterized by several specific genomic features as broad ploidy variation, high chromosome numbers, presence of ...

Pigmentation Pathway Evolution after Whole-Genome Duplication in Fish [PDF]
Genome Biology and Evolution, 2009 Whole-genome duplications (WGDs) have occurred repeatedly in the vertebrate lineage, but their evolutionary significance for phenotypic evolution remains elusive. Here, we have investigated the impact of the fish-specific genome duplication (FSGD) on the evolution of pigmentation pathways in teleost fishes.

Beyond the Whole-Genome Duplication: Phylogenetic Evidence for an Ancient Interspecies Hybridization in the Baker's Yeast Lineage. [PDF]
PLoS Biology, 2015 Whole-genome duplications have shaped the genomes of several vertebrate, plant, and fungal lineages. Earlier studies have focused on establishing when these events occurred and on elucidating their functional and evolutionary consequences, but we still ...

Gene duplicability of core genes is highly consistent across all angiosperms [PDF]
, 2016 Gene duplication is an important mechanism for adding to genomic novelty. Hence, which genes undergo duplication and are preserved following duplication is an important question. It has been observed that gene duplicability, or the ability of genes to be

Whole Genome Duplication in the Genomics Era: The Hidden Gems in Invertebrates? [PDF]
Genome Biol EvolAbstract Whole genome duplication (WGD) events generate potent new genomic resources for rewiring existing genetic regulatory networks. Studying WGDs in vertebrates is of considerable importance to understand vertebrate evolution. Recent studies have shown that different invertebrate lineages, including lophotrochozoans/spiralians and ...
