Multigene families and vestigial sequences [PDF]

Proceedings of the National Academy of Sciences, 1986
Random duplication and deletion events generate complex genomes carrying a large amount of dispensable sequences. We have simulated such events in a computer model. We followed the evolution of a genome carrying at least one copy of each type of gene.

Emergence and Prevalence of an African Swine Fever Virus Variant in Wild Boar Populations in South Korea from 2019 to 2022

Viruses, 2023
African swine fever (ASF), a viral disease caused by the African swine fever virus (ASFV), is associated with high mortality rates in domestic pigs and wild boars. ASF has been spreading since its discovery in wild boars in Korea in October 2019. Genomic

Species-Specific Duplication of Surface Antigen Genes in Paramecium

Microorganisms, 2022
Paramecium is a free-living ciliate that undergoes antigenic variation and still the functions of these variable surface antigen coats in this non-pathogenic ciliate remain elusive.

Pleiotropic fitness effects of a Drosophila odorant-binding protein

G3: Genes, Genomes, Genetics, 2022
Insect odorant-binding proteins (OBPs) are members of a rapidly evolving multigene family traditionally thought to facilitate chemosensation. However, studies on DrosophilaObp56hD.

Antigenicity and adhesiveness of a Plasmodium vivax VIR-E protein from Brazilian isolates

Memorias do Instituto Oswaldo Cruz, 2022
BACKGROUND Plasmodium vivax, the major cause of malaria in Latin America, has a large subtelomeric multigene family called vir. In the P. vivax genome, about 20% of its sequences are vir genes.

Evolution of Guanylate Binding Protein (GBP) Genes in Muroid Rodents (Muridae and Cricetidae) Reveals an Outstanding Pattern of Gain and Loss

Frontiers in Immunology, 2022
Guanylate binding proteins (GBPs) are paramount in the host immunity by providing defense against invading pathogens. Multigene families related to the immune system usually show that the duplicated genes can either undergo deletion, gain new functions ...

Cloning and Characterization of Two Phosphate Transporters from Medicago truncatula Roots: Regulation in Response to Phosphate and to Colonization by Arbuscular Mycorrhizal (AM) Fungi

Molecular Plant-Microbe Interactions, 1998
Most vascular plants can acquire phosphate from the environment either directly, via the roots, or indirectly, via a fungal symbiont that invades the cortical cells of the root. Here we have identified two cDNA clones (MtPT1 and MtPT2) encoding phosphate

Functional relevance of the newly evolved sperm dynein intermediate chain multigene family in Drosophila melanogaster males. [PDF]

, 2012
In many animal species, traits associated with male fitness evolve rapidly. Intersexual conflict and male-male competition have been suggested to drive this rapid evolution.

A new computational approach redefines the subtelomeric vir superfamily of Plasmodium vivax

BMC Genomics, 2013
Background Subtelomeric multigene families of malaria parasites encode virulent determinants. The published genome sequence of Plasmodium vivax revealed the largest subtelomeric multigene family of human malaria parasites, the vir super-family, presently

Cadmium-induced ethylene production and responses in Arabidopsis thaliana rely on ACS2 and ACS6 gene expression [PDF]

, 2014
Background: Anthropogenic activities cause metal pollution worldwide. Plants can absorb and accumulate these metals through their root system, inducing stress as a result of excess metal concentrations inside the plant.
