Evidence for sub-functionalization of tandemly duplicated XPB nucleotide excision repair genes in Arabidopsis thaliana
(2020-09-05)
Plants are continuously exposed to agents that can generate DNA lesions. Nucleotide Excision Repair (NER) is one of the repair pathways employed by plants to protect their genome, including from sunlight. The Xeroderma ...
Convergent evolution of neo-functionalized duplications of ATP1A1 in dendrobatid and grass frogs
(Universidad de los AndesMaestría en Ciencias BiológicasFacultad de CienciasDepartamento de Ciencias Biológicas, 2022-06-17)
Gene duplication followed by adaptive divergence is an important source of molecular novelty and thus evolutionary innovation. Gene duplication followed by neofunctionalization can create a tension between natural selection ...
Subfunctionalization reduces the fitness cost of gene duplication in human by buffering dosage imbalances
(BioMed Central, 2011-12)
Background
Driven essentially by random genetic drift, subfunctionalization has been identified as a possible non-adaptive mechanism for the retention of duplicate genes in small-population species, where widespread ...
The fate of duplicate genes in plantsDestino evolutivo de genes duplicados em plantas
(Universidade Federal de Viçosa, 2016)
A duplicated copy of id2b is an unusual sex-determining candidate gene on the Y chromosome of arapaima (Arapaima gigas)
(2021-12-01)
Arapaima gigas is one of the largest freshwater fish species of high ecological and economic importance. Overfishing and habitat destruction are severe threats to the remaining wild populations. By incorporating a chromosomal ...
Partial cDNA sequence analysis of myosin Va from rainbow trout (Oncorhynchus mykiss) and its relationship to myosin v isoforms from other vertebrates.
(2008-01-01)
Partial cDNA sequences of myosin V from rainbow trout Oncorhynchus mykiss were analyzed and showed high similarity to MVa from other vertebrates. Phylogenetic analysis has shown that events resulting in the formation of ...

Evolução do gene da proteína centromérica Cenp-C em espécies de Drosophila do grupo montium
(Universidade Federal de Minas GeraisBrasilICB - INSTITUTO DE CIÊNCIAS BIOLOGICASPrograma de Pós-Graduação em GenéticaUFMG, 2022-01-28)
The centromere is the region necessary for chromosomal segregation in eukaryotes. In animals and plants, functional centromeres are initiated by the interaction between satellite DNAs and the Cenp-A protein, a variant of ...
Evolutionary History of Arabidopsis thaliana Aminoacyl-tRNA Synthetase Dual-Targeted Proteins
(OXFORD UNIV PRESS, 2011)
Aminoacyl-transfer RNA (tRNA) synthetases (aaRS) are key players in translation and act early in protein synthesis by mediating the attachment of amino acids to their cognate tRNA molecules. In plants, protein synthesis ...
The 5S rDNA family evolves through concerted and birth-and-death evolution in fish genomes: an example from freshwater stingrays
(Biomed Central Ltd., 2011-05-31)
Background: Ribosomal 5S genes are well known for the critical role they play in ribosome folding and functionality. These genes are thought to evolve in a concerted fashion, with high rates of homogenization of gene copies. ...
