Inference of Ancient Whole-Genome Duplications and the Evolution of Gene Duplication and Loss Rates.

Molecular biology and evolution, 2019
Gene tree-species tree reconciliation methods have been employed for studying ancient whole-genome duplication (WGD) events across the eukaryotic tree of life.

STRIDE: Species Tree Root Inference from Gene Duplication Events

bioRxiv, 2017
The correct interpretation of a phylogenetic tree is dependent on it being correctly rooted. A gene duplication event at the base of a clade of species is synapamorphic, and thus excludes the root of the species tree from that clade. We present STRIDE, a

Altered patterns of gene duplication and differential gene gain and loss in fungal pathogens

BMC Genomics, 2008
Background Duplication, followed by fixation or random loss of novel genes, contributes to genome evolution. Particular outcomes of duplication events are possibly associated with pathogenic life histories in fungi.

Resolving noise–control conflict by gene duplication

bioRxiv, 2019
Gene duplication promotes adaptive evolution in two principle ways: allowing one duplicate to evolve a new function and resolving adaptive conflicts by splitting ancestral functions between the duplicates.

An Overview of Duplicated Gene Detection Methods: Why the Duplication Mechanism Has to Be Accounted for in Their Choice

Genes, 2020
Gene duplication is an important evolutionary mechanism allowing to provide new genetic material and thus opportunities to acquire new gene functions for an organism, with major implications such as speciation events. Various processes are known to allow

Glyphosate Resistance and EPSPS Gene Duplication: Convergent Evolution in Multiple Plant Species.

Journal of Heredity, 2018
One of the increasingly widespread mechanisms of resistance to the herbicide glyphosate is copy number variation (CNV) of the 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) gene.

Hierarchy and Feedback in the Evolution of the E. coli Transcription Network [PDF]

, 2007
The E.coli transcription network has an essentially feedforward structure, with, however, abundant feedback at the level of self-regulations. Here, we investigate how these properties emerged during evolution.

Distinguish between Duplication of Essential Genes and Duplication of Dispensable Genes [PDF]

, 2020
AbstractWhen a dispensable gene is duplicated (ancestral dispensability), genetic buffering and duplicate compensation together maintain the gene dispensability, whereas duplicate compensation is the only mechanism when an essential gene is duplicated (ancestral essentiality).

Comparative Genomics Reveals Gene Duplication and Evolution in 26 Aurantioideae Species

Horticulturae
Gene duplication, as a prevalent phenomenon in the tree of life, provides a potential substrate for evolution. However, its role in the Aurantioideae remains unclear.

Chromosome mapping of dragline silk genes in the genomes of widow spiders (araneae, theridiidae) [PDF]

, 2010
With its incredible strength and toughness, spider dragline silk is widely lauded for its impressive material properties. Dragline silk is composed of two structural proteins, MaSp1 and MaSp2, which are encoded by members of the spidroin gene family ...
