Genetic diversity and mating systems in a mass-reared black soldier fly (Hermetia illucens) population
(Stellenbosch : Stellenbosch University, 2021-03)ENGLISH ABSTRACT: Black soldier flies are gaining popularity as an alternative source of protein in animal feed. They have a high feed conversion ratio and can be reared on biowaste, reducing the energy input required for ... -
Investigation in South Africa of viruses implicated in a maize lethal necrosis disease outbreak in East Africa
(Stellenbosch : Stellenbosch University, 2021-03)ENGLISH ABSTRACT: Virus diseases of maize (Zea mays) such as maize streak virus (MSV) and the recently identified maize lethal necrosis disease (MLND) may result in severe to complete maize yield losses for individual ... -
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 ... -
The Potential Regulatory Role of microRNA in Methamphetamine Use Disorder (MUD)
(Stellenbosch : Stellenbosch University, 2020-12)ENGLISH ABSTRACT: Methamphetamine (MA) is a psychostimulant affecting the central nervous system. Individuals with methamphetamine use disorder (MUD) present compulsive substance-seeking behaviour and impaired control ... -
Identification of a cellulolytic active fungal strain, isolated from a cigarette waste microenvironment, showing preference for growth on cellulose acetate
(Stellenbosch : Stellenbosch University, 2020-12)ENGLISH ABSTRACT: Globally, environmental pollution such as greenhouse gases and microplastics are ubiquitous throughout nature. Long-term negative environmental effects and bioaccumulation of anthropogenic compounds ... -
Genetic Diversity and Population Structure of the critically endangered freshwater fish species, the Clanwilliam sandfish (Labeo seeberi)
(Stellenbosch : Stellenbosch University, 2020-12)ENGLISH ABSTRACT: Labeo spp. are large freshwater fish found throughout southern Asia, the Middle East and Africa. The genus is characterised by specialised structures around the mouth and lips making it adapted to herbivorous ... -
Analysis of the role of transcription factors in enhancing drought tolerance in sugarcane (Saccharum spp.)
(Stellenbosch : Stellenbosch University, 2020-12)ENGLISH ABSTRACT: Sugarcane is a large perennial grass of the genus Saccharum. Economically, this grass species is an important source of sugar for food purposes and biomass for biofuel production. However, the sustainability ... -
Genetic diversity and spatial patterns of distribution of Citrus greening disease and its vectors in East Africa
(Stellenbosch : Stellenbosch University, 2020-12)ENGLISH ABSTRACT: Citrus spp is an important cash crop supporting millions of households in East Africa. However, the crop faces challenges of infestation by pests and diseases that lead to substantial economic loss. ... -
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 ... -
Characterization of the Sucrose Synthase and class II Trehalose 6-Phosphate Synthase gene families in the moss Physcomitrella patens.
(Stellenbosch : Stellenbosch University, 2020-12)ENGLISH ABSTRACT: Plant sugars have dual functionality, in that they play a role in primary metabolism and partake in signal transduction pathways. As it relates to their signaling function, they relay information to 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 ... -
