Genetic and morphological variation of the lanternfish lampanyctodes hectoris (myctophiformes: myctophidae) off Southern Africa
(Taylor and Francis Group, 2001)Genetic and morphological variation within the southern African population of Lampanyctodes hectoris was analysed. A total of 15 enzymes, encoding 22 isozyme loci, was examined (n = 327); seven were polymorphic. The ... -
Genetic association of solute carrier transporter gene variants with metformin response
(Balkan Journal of Medical Genetics, 2021)Type 2 diabetes mellitus (T2DM) is a metabolic disorder characterized by elevated blood glucose levels and is influenced by both genetic and environmental factors. It is treated with various classes of oral antidiabetic ... -
Genetic characterisation of Campylobacter concisus: Strategies for improved genomospecies discrimination
(Elsevier, 2021)Although at least two genetically distinct groups, or genomospecies, have been well documented for Campylobacter concisus, no phenotype has yet been identified for their differentiation and thus formal description as ... -
Genetic characterization of the central variable region in African swine fever virus isolates in the Russian federation from 2013 to 2017
(MDPI, 2022)African swine fever virus (ASFV), classified as genotype II, was introduced into Georgia in 2007, and from there, it spread quickly and extensively across the Caucasus to Russia, Europe and Asia. The molecular epidemiology ... -
Genetic diversity, population structure and marker- trait association for 100-seed weight in international safflower panel using silicodart marker information
(MDPI, 2020)Safflower is an important oilseed crop mainly grown in the arid and semi-arid regions of the world. The aim of this study was to explore phenotypic and genetic diversity, population structure, and marker-trait association ... -
A genetic geomorphic classification system for Southern African palustrine wetlands: Global implications for the management of wetlands in drylands
(Frontiers, 2019)Due to climatic constraints in dryland regions, wetlands usually occur at confluences of flow paths, whether from surface flow, inter-flow or at locations of groundwater discharge. Long-term landscape processes that shape ... -
Genetic heritage of the Baphuthi highlights an over-ethnicized notion of “Bushman” in the Maloti-Drakensberg, southern Africa
(Cell Press, 2023)Using contemporary people as proxies for ancient communities is a contentious but necessary practice in anthropology. In southern Africa, the distinction between the Cape KhoeSan and eastern KhoeSan remains unclear, as ... -
Genetic landscape of the mitochondrial DNA control region in South African populations
(ScienceDirect, 2019)A high-quality dataset of the mitochondrial DNA control region sequences was generated with Sanger and next-generation sequencing. The study was aimed at characterizing the maternal genetic ancestry and analyzing the ... -
Genetic lesions within the 3a gene of SARS-CoV
(BioMed Central, 2005)A series of frameshift mutations within the 3a gene has been observed in culture-derived severe acute respiratory syndrome coronavirus (SARS-CoV). We report here that viral RNA from clinical samples obtained from SARS-CoV ... -
The genetic organisation of a 2,966 basepair DNA fragment of a Single Capsid Nucleopolyhedrovirus isolated from Trichoplusia ni
(Springer Verlag, 2002)In order to investiagte the genomic organization of the Trichoplusia ni Single Capsid Nucleoplyhedrovirus (TnSNPV) , a 2,966 base pairs (bp) genomic fragment was sequenced. The fragment was found to contain five open reading ... -
Genetic polymorphisms and haplotypes of the organic cation transporter 1 gene (SLC22A1) in the Xhosa population of South Africa
(Brazilian Society of Genetics, 2014)Human organic cation transporter 1 is primarily expressed in hepatocytes and mediates the electrogenic transport of various endogenous and exogenous compounds, including clinically important drugs. Genetic polymorphisms ... -
Genetic variation and population structure of Botswana populations as identified with AmpFLSTR Identifiler short tandem repeat (STR) loci
(Nature Publishing Group, 2017-07-28)Population structure was investigated in 990 Botswana individuals according to ethno-linguistics, Bantu and Khoisan, and geography (the nine administrative districts) using the Identifiler autosomal microsatellite markers. ... -
Genetic variation in responses to salt stress in Tunisian populations of Medicago ciliaris
(MDPI, 2022)Soil salinity is one of the most serious environmental factors affecting crop productivity around the world. We used a morpho-physiological approach to investigate the salt responses of four Tunisian natural populations ... -
Genome sequence of an alkaliphilus species isolated from historically contaminated sediments of the gulf of Naples (Mediterranean Sea)
(American Society for Microbiology, 2021)Here, we report the draft genome sequence of a metagenome-assembled genome (MAG) of a new Alkaliphilus bacterium, NP8, of the Clostridiaceae family. This bacterium was isolated from polluted sediment collected from an ... -
Genome sequence of the tsetse fly (glossina morsitans): vector of African trypanosomiasis
(American Association for the Advancement of Science, 2014)Tsetse flies are the sole vectors of human African trypanosomiasis throughout sub-Saharan Africa. Both sexes of adult tsetse feed exclusively on blood and contribute to disease transmission. Notable differences between ... -
Genome sequences of three vaccine strains and two wild-type canine distemper virus strains from a recent disease outbreak in South Africa
(American Society for Microbiology, 2017)Canine distemper virus causes global multihost infectious disease. This report details complete genome sequences of three vaccine and two new wild-type strains. The wild-type strains belong to the South African lineage, ... -
