Global population genetic structure and demographic trajectories of the black soldier fly, Hermetia illucens
(BMC, 2021-05-05)Background: The black soldier fly (Hermetia illucens) is the most promising insect candidate for nutrient-recycling through bioconversion of organic waste into biomass, thereby improving sustainability of protein supplies ... -
Unravelling the interaction between the DRD2 and DRD4 genes, personality traits and concussion risk
(BMJ Publishing Group, 2019)Background: Concussion occurs when biomechanical forces transmitted to the head result in neurological deficits. Personality may affect the balance between safe and dangerous play potentially influencing concussion ... -
Expression of a small ubiquitin-like modifier Protease increases drought tolerance in wheat (Triticum aestivum L.)
(Frontiers, 2019-03-08)Post-translation modification of proteins plays a critical role in cellular signaling processes. In recent years, the SUMO (Small Ubiquitin-Like Modifier) class of molecules has emerged as an influential mechanism for ... -
Toward the identification of a phytocannabinoid-like compound in the flowers of a South African medicinal plant (Leonotis leonurus)
(BMC (part of Springer Nature), 2020-11-10)Objective: Current global trends on natural therapeutics suggest an increasing market interest toward the use and discovery of new plant-derived therapeutic compounds, often referred to as traditional medicine (TM). The ... -
Towards the validation of high-throughput sequencing (HTS) for routine plant virus diagnostics: measurement of variation linked to HTS detection of citrus viruses and viroids
(BioMed Central, 2021-03-22)Background: High-throughput sequencing (HTS) has been applied successfully for virus and viroid discovery in many agricultural crops leading to the current drive to apply this technology in routine pathogen detection. ... -
New mitochondrial gene rearrangement in psyttalia concolor, p. humilis and p. lounsburyi (hymenoptera: braconidae), three parasitoid species of economic interest
(MDPI, 2020-12-02)The family Braconidae consists mostly of specialized parasitoids, some of which hold potential in biocontrol of agricultural pests. Psyttalia concolor, Psyttalia humilis and Psyttalia lounsburyi are parasitoids associated ... -
Characterisation of different GLRaV-3 variant infections by determining virus concentration ratios and miRNA expression profiles
(Bundesanstalt fur Zuchtungsforschung an Kulturpflanzen, 2019)Grapevine leafroll disease (GLD) is present in all grape-growing regions of the world and is considered the most significant grapevine viral disease. Grapevine leafroll-associated virus 3 (GLRaV-3) is considered the primary ... -
Mitochondrial genetic variation reveals phylogeographic structure and cryptic diversity in Trioza erytreae
(Nature Research (part of Springer Nature), 2020)Trioza erytreae is the main vector for ‘Candidatus Liberibacter africanus’, the causative agent of African Citrus Greening disease. The insect is widespread in Africa, and has recently disseminated to Southwestern Europe. ... -
DNA methylation and demethylation are regulated by functional DNA methyltransferases and DnTET enzymes in diuraphis noxia
(Frontiers Media, 2020)Aphids are economically important insect pests of crops worldwide. Despite resistant varieties being available, resistance is continuously challenged and eventually broken down, posing a threat to food security. In the ... -
The application of a commercially available citrus-based extract mitigates moderate NaCl-stress in arabidopsis thaliana plants
(MDPI, 2020)Aims: The aim of this study was to assess the effect of BC204 as a plant biostimulant on Arabidopsis thaliana plants under normal and NaCl-stressed conditions. Methods: For this study, ex vitro and in vitro growth experiments ... -
Wheat line “RYNO3936” is associated with delayed water stress-induced leaf senescence and rapid water-deficit stress recovery
(Frontiers Media, 2020)Random mutagenesis was applied to produce a new wheat mutant (RYNO3926) with superior characteristics regarding tolerance to water deficit stress induced at late booting stage. The mutant also displays rapid recovery from ... -
Phylogeography, genetic diversity, and population structure of Nile crocodile populations at the fringes of the southern African distribution
(Public Library of Science, 2018)Nile crocodiles are apex predators widely distributed in sub-Saharan Africa that have been viewed and managed as a single species. A complex picture of broad and fine-scale phylogeographic patterns that includes the ... -
The complete mitochondrial genome and phylogenetic position of the leopard catshark, Poroderma pantherinum
(Taylor & Francis Open, 2018)We present the first mitochondrial genome of a South African endemic catshark, Poroderma pantherinum. The complete mitogenome is 16,686 bp in length, comprising 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and ... -
Modification of cassava root starch phosphorylation enhances starch functional properties
(Frontiers Media, 2018)Cassava (Manihot esculenta Crantz) is a root crop used as a foodstuff and as a starch source in industry. Starch functional properties are influenced by many structural features including the relative amounts of the two ... -
Repression of sex4 and like sex four2 orthologs in potato increases tuber starch bound phosphate with concomitant alterations in starch properties physical
(Frontiers Media, 2018-07-23)To examine the roles of starch phosphatases in potatoes, transgenic lines were produced where orthologs of SEX4 and LIKE SEX FOUR2 (LSF2) were repressed using RNAi constructs. Although repression of either SEX4 or LSF2 ... -
