Phylogenomics of Asgard archaea reveals a unique blend of prokaryotic-like horizontal transfer and eukaryotic-like gene duplication [PDF]

Nature Communications
Asgard archaea hold a pivotal position in the tree of life as the closest known relatives to eukaryotes and are therefore crucial for understanding eukaryogenesis.

Can Introns Stabilize Gene Duplication?

Biology, 2022
Gene duplication is considered one of the most important events that determine the evolution of genomes. However, the neo-duplication condition of a given gene is particularly unstable due to recombination events. Several mechanisms have been proposed to

The Importance of Gene Duplication and Domain Repeat Expansion for the Function and Evolution of Fertilization Proteins

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.

Whole-genome and dispersed duplication, including transposed duplication, jointly advance the evolution of TLP genes in seven representative Poaceae lineages

BMC Genomics, 2023
Background In the evolutionary study of gene families, exploring the duplication mechanisms of gene families helps researchers understand their evolutionary history.

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 ...

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 ...

Acquisition of new function through gene duplication in the metallocarboxypeptidase family

Scientific Reports, 2023
Gene duplication is a key first step in the process of expanding the functionality of a multigene family. In order to better understand the process of gene duplication and its role in the formation of new enzymes, we investigated recent duplication ...

Promoter evolution of mammalian gene duplicates

BMC Biology, 2023
Background Gene duplication is thought to be a central process in evolution to gain new functions. The factors that dictate gene retention following duplication as well paralog gene divergence in sequence, expression and function have been extensively ...

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.
