A multigene family encoding surface glycoproteins in Trypanosoma congolense [PDF]

open access: yesMicrobial Cell, 2017
Trypanosoma congolense, the causative agent of the most important livestock disease in Africa, expresses specific surface proteins involved in its parasitic lifestyle. Unfortunately, the complete repertoire of such molecules is far from being deciphered.

Telemedicine Competencies in Family Medicine Clerkships: A CERA Study [PDF]

open access: yes, 2023
Background: While the Association of American Medical Colleges (AAMC) designated cross-disciplinary telemedicine competencies, curricular implementation is at disparate stages across medical schools and with significant curricular gaps.

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

open access: yesFrontiers 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 ...

Multigene families and vestigial sequences [PDF]

open access: yesProceedings 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.

Architecture, Chromatin and Gene Organization of Toxoplasma gondii Subtelomeres

open access: yesEpigenomes, 2022
Subtelomeres (ST) are chromosome regions that separate telomeres from euchromatin and play relevant roles in various biological processes of the cell. While their functions are conserved, ST structure and genetic compositions are unique to each species ...

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

open access: yesMolecular 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

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

open access: yesViruses, 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

open access: yesMicroorganisms, 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.

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

open access: yesBMC 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

T2prhd: a tool to study the patterns of repeat evolution [PDF]

open access: yes, 2008
BACKGROUND: The models developed to characterize the evolution of multigene families (such as the birth-and-death and the concerted models) have also been applied on the level of sequence repeats inside a gene/protein.
