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.

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

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.

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

Multigene families in African swine fever virus: family 505 [PDF]

Journal of Virology, 1994
Sequencing of restriction fragment EcoRI A-SalI C of African swine fever virus has revealed the existence of a multigene family, designated family 505 because of the average number of amino acids in the proteins, composed of seven homologous and tandemly arranged genes. All the genes of family 505 are expressed during infection.

Molecular Organization and Chromosomal Localization Analysis of 5S rDNA Clusters in Autotetraploids Derived From Carassius auratus Red Var. (♀) × Megalobrama amblycephala (♂)

Frontiers in Genetics, 2019
The autotetraploid fish (4n = 200, RRRR) (abbreviated as 4nRR) resulted from the whole genome duplication of red crucian carp (Carassius auratus red var., 2n = 100, RR) (abbreviated as RCC).

Variant Exported Blood-Stage Proteins Encoded by Plasmodium Multigene Families Are Expressed in Liver Stages Where They Are Exported into the Parasitophorous Vacuole.

PLoS Pathogens, 2016
Many variant proteins encoded by Plasmodium-specific multigene families are exported into red blood cells (RBC). P. falciparum-specific variant proteins encoded by the var, stevor and rifin multigene families are exported onto the surface of infected red
