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, ... -
Genome sequencing of a severe acute respiratory syndrome Coronavirus 2 isolate obtained from a South African patient with Coronavirus disease 2019
(American Society for Microbiology, 2020)As a contribution to the global efforts to track and trace the ongoing coronavirus pandemic, here we present the sequence, phylogenetic analysis, and modeling of nonsynonymous mutations for a severe acute respiratory ... -
Genome-wide SNP identification by high-throughput sequencing and selective mapping allows sequence assembly positioning using a framework genetic linkage map
(BioMed Central, 2010)Determining the position and order of contigs and scaffolds from a genome assembly within an organism’s genome remains a technical challenge in a majority of sequencing projects. In order to exploit contemporary technologies ... -
Genomic association of single nucleotide polymorphisms with blood pressure response to hydrochlorothiazide among south african adults with hypertension
(MDPI, 2020): This study described single nucleotide polymorphisms (SNPs) in hydrochlorothiazideassociated genes and further assessed their correlation with blood pressure control among South African adults living with hypertension. ... -
Genomic characterization of a prophage, Smhb1, that Infects Salinivibrio kushneri BNH isolated from a Namib Desert saline spring
(MDPI, 2021)Recent years have seen the classification and reclassification of many viruses related to the model enterobacterial phage P2. Here, we report the identification of a prophage (Smhb1) that infects Salinivibrio kushneri BNH ... -
Geochemistry and weathering history of the Balfour sandstone formation, Karoo basin, South Africa: Insight to provenance and tectonic setting
