Molecular characterisation of apple accessions with respect to aminocyclopropane-1-carboxylic acid synthase gene (ACS1) polymorphism
(Czech Academy of Agricultural Sciences, 2020-02-07)The ARC apple gene bank collection was genotyped for the fruit expressed gene ACS1, in which a short-interspersed element (SINE) in the promoter is known, when homozygous, to correlate with the delayed ethylene production. ... -
Distinct host-immune response toward species related intracellular mycobacterial killing : a transcriptomic study
(Taylor & Francis, 2020)The comparison of the host immune response when challenged with pathogenic and nonpatho- genic species of mycobacteria can provide answers to the unresolved question of how pathogens subvert or inhibit an effective ... -
Hepatic and haemato-biochemical alterations in juvenile Mozambique tilapia (oreochromis mossambicus) on pawpaw (carica papaya) seed meal
(Canadian Center of Science and Education, 2019-06-15)Pawpaw seed meal (PSM) can be used as an antifertility agent in animals, however there is no information on its potential toxicological effect on Mozambique tilapia (O. mossambicus). In this study the effect of PSM on the ... -
Hormonal profile and reproductive parameters of pre-vitellogenic mozambique tilapia (oreochromis mossambicus) on pawpaw (carica papaya) seed meal
(Canadian Center of Science and Education, 2019-06-15)The use of phytochemicals to control precocious maturation and indiscriminate spawning among tilapia species is an important issue in aquaculture. This study investigated the influence of pawpaw (Carica papaya) seed meal ... -
Draft genome sequence of a “candidatus phytoplasma asteris” - related strain (aster yellows, subgroup 16SrI-B) from South Africa
(American Society for Microbiology, 2019-04-25)Here, we report the draft genome sequence of a phytoplasma discovered in grapevine. The genome size is 600,116 nucleotides (nt), with 597 predicted open reading frames. It is most similar to a maize bushy stunt phytoplasma ... -
Defining biotechnological solutions for insect control in sub-Saharan Africa
(Wiley Open Access, 2019)Africa is burdened by food insecurity with nearly a billion people suffering from starvation, undernutrition, and malnutrition. Climate change prediction models forecast changes in rainfall patterns and rising temperature ... -
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 ... -
