Gene Complexity and Gene Duplicability [PDF]
Current Biology, 2005 Eukaryotic genes are on average more complex than prokaryotic genes in terms of expression regulation, protein length, and protein-domain structure [1-5]. Eukaryotes are also known to have a higher rate of gene duplication than prokaryotes do [6, 7]. Because gene duplication is the primary source of new genes [], the average gene complexity in a genome

Patterns of gene evolution following duplications and speciations in vertebrates [PDF]
PeerJ, 2020 Background Eukaryotic genes typically form independent evolutionary lineages through either speciation or gene duplication events. Generally, gene copies resulting from speciation events (orthologs) are expected to maintain similarity over time with ...

Frontiers in Cell and Developmental Biology, 2022 The process of gene duplication followed by gene loss or evolution of new functions has been studied extensively, yet the role gene duplication plays in the function and evolution of fertilization proteins is underappreciated.

Phylogenetic analysis reveals an ancient gene duplication as the origin of the MdtABC efflux pump. [PDF]
, 2020 The efflux pumps from the Resistance-Nodulation-Division family, RND, are main contributors to intrinsic antibiotic resistance in Gram-negative bacteria. Among this family, the MdtABC pump is unusual by having two inner membrane components.

Expectations of Duplicate Gene Retention Under the Gene Duplicability Hypothesis
BMC Ecology and Evolution, 2023 Abstract Background Gene duplication is an important process in evolution. What causes some genes to be retained after duplication and others to be lost is a process not well understood. The most prevalent theory is the gene duplicability hypothesis, that something about the function and number of interacting partners (number of subunits of ...

Duplicate Genes Contribute to Variability in Abiotic Stress Resistance in Allopolyploid Wheat
Plants, 2023 Gene duplication is a universal biological phenomenon that drives genomic variation and diversity, plays a crucial role in plant evolution, and contributes to innovations in genetic engineering and crop development.

Gene Dosage and Gene Duplicability [PDF]
Genetics, 2008 Abstract The evolutionary process leading to the fixation of newly duplicated genes is not well understood. It was recently proposed that the fixation of duplicate genes is frequently driven by positive selection for increased gene dosage (i.e., the gene dosage hypothesis), because haploinsufficient genes were reported to have more ...

Phylogenomics: gene duplication, unrecognized paralogy and outgroup choice. [PDF]
PLoS ONE, 2009 Comparative genomics has revealed the ubiquity of gene and genome duplication and subsequent gene loss. In the case of gene duplication and subsequent loss, gene trees can differ from species trees, thus frequent gene duplication poses a challenge for ...
