Systematic bacterialization of yeast genes identifies a near-universally swappable pathway

open access: yeseLife, 2017
Eukaryotes and prokaryotes last shared a common ancestor ~2 billion years ago, and while many present-day genes in these lineages predate this divergence, the extent to which these genes still perform their ancestral functions is largely unknown. To test

OrthoGNC: A Software for Accurate Identification of Orthologs Based on Gene Neighborhood Conservation

open access: yesGenomics, Proteomics & Bioinformatics, 2017
Orthology relations can be used to transfer annotations from one gene (or protein) to another. Hence, detecting orthology relations has become an important task in the post-genomic era.

Ortholog-Finder: A Tool for Constructing an Ortholog Data Set [PDF]

open access: yesGenome Biology and Evolution, 2016
Orthologs are widely used for phylogenetic analysis of species; however, identifying genuine orthologs among distantly related species is challenging, because genes obtained through horizontal gene transfer (HGT) and out-paralogs derived from gene duplication before speciation are often present among the predicted orthologs.

Gene tree correction guided by orthology [PDF]

open access: yes, 2013
International audienceBackgroundReconciled gene trees yield orthology and paralogy relationships between genes. This information may however contradict other information on orthology and paralogy provided by other footprints of evolution, such as ...

Proteinortho6: pseudo-reciprocal best alignment heuristic for graph-based detection of (co-)orthologs

open access: yesFrontiers in Bioinformatics, 2023
Proteinortho is a widely used tool to predict (co)-orthologous groups of genes for any set of species. It finds application in comparative and functional genomics, phylogenomics, and evolutionary reconstructions.

An Implication in Orthologic

open access: yesInternational Journal of Theoretical Physics, 2005
We involve a certain propositional logic based on ortholattices. We characterize the implicational reduct of such a logic and we show that its algebraic counterpart is the so-called orthosemilattice. Properties of congruences and congruence kernels of these algebras are described.

Protein-Gene Orthology in Baculoviridae: An Exhaustive Analysis to Redefine the Ancestrally Common Coding Sequences

open access: yesViruses, 2023
Baculoviruses are entomopathogens that carry large, double-stranded circular DNA genomes and infect insect larvae of Lepidoptera, Hymenoptera and Diptera, with applications in the biological control of agricultural pests, in the production of recombinant

A Reliable Neighbor-Based Method for Identifying Essential Proteins by Integrating Gene Expressions, Orthology, and Subcellular Localization Information

open access: yesTsinghua Science and Technology, 2016
Essential proteins are those necessary for the survival or reproduction of species and discovering such essential proteins is fundamental for understanding the minimal requirements for cellular life, which is also meaningful to the disease study and drug

Disparate Inventories of Hypoxia Gene Sets Across Corals Align With Inferred Environmental Resilience

open access: yesFrontiers in Marine Science, 2022
Aquatic deoxygenation has been flagged as an overlooked but key factor contributing to mass bleaching-induced coral mortality. During deoxygenation events triggered by coastal nutrient pollution and ocean warming, oxygen supplies lower to concentrations ...
