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 ... -
Confirmation of the effectiveness and genetic positions of disease resistance loci in ‘Kishmish Vatkana’ (Ren1) and ‘Villard Blanc’ (Ren3 and Rpv3)
(South African Society for Enology and Viticulture, 2018)This study aimed to validate the effectiveness and to genetically characterise the fungal disease resistance genes of ‘Kishmish Vatkana’ and ‘Villard Blanc’ in South Africa using microsatellite (SSR) markers and a ... -
Mutations in glucan, water dikinase affect starch degradation and gametophore development in the moss physcomitrella patens
(Nature Research, 2019)The role of starch degradation in non-vascular plants is poorly understood. To expand our knowledge of this area, we have studied this process in Physcomitrella patens. This has been achieved through examination of the ... -
The structure and function of the global citrus rhizosphere microbiome
(Nature Research (part of Springer Nature), 2018)Citrus is a globally important, perennial fruit crop whose rhizosphere microbiome is thought to play an important role in promoting citrus growth and health. Here, we report a comprehensive analysis of the structural and ... -
Starch trek : the search for yield
(Frontiers Media, 2019)Starch is a plant storage polyglucan that accumulates in plastids. It is composed of two polymers, amylose and amylopectin, with different structures and plays several roles in helping to determine plant yield. In leaves, ... -
Population genetics of Southern Hemisphere tope shark (Galeorhinus galeus) : Intercontinental divergence and constrained gene flow at different geographical scales
(Public Library of Science, 2017)The tope shark (Galeorhinus galeus Linnaeus, 1758) is a temperate, coastal hound shark found in the Atlantic and Indo-Pacific oceans. In this study, the population structure of Galeorhinus galeus was determined across the ... -
A comparative study of selected physical and biochemical traits of wild-type and transgenic sorghum to reveal differences relevant to grain quality
(Frontiers Media, 2017)Transgenic sorghum featuring RNAi suppression of certain kafirins was developed recently, to address the problem of poor protein digestibility in the grain. However, it was not firmly established if other important quality ... -
Monetary value of the impacts of filamentous green algae on commercial agriculture : results from two geographically different case studies
(South African Water Research Commission, 2016-07)This paper presents estimates of the monetary value of the impact of eutrophication (algae) on commercial agriculture in two different catchments in South Africa. A production function approach is applied to estimate the ... -
Microsatellite-based DNA fingerprinting of selected grapevine cultivars
(South African Society for Enology and Viticulture, 2018)Cultivar identification by ampelography is often difficult and is sensitive to environmental conditions, thus it can be problematic to distinguish between closely related cultivars. DNA fingerprinting offers an alternative ... -
Genome of Russian wheat aphid an economically important cereal aphid
(BioMed Central, 2017-12-28)Although the hemipterans ( Aphididae ) are comprised of roughly 50,000 extant insect species, only four have sequenced genomes that are publically available, namely ... -
In silico analysis of the grapefruit sRNAome, transcriptome and gene regulation in response to CTV-CDVd co-infection
(BioMed Central, 2017)Background: Small RNA (sRNA) associated gene regulation has been shown to play a significant role during plant-pathogen interaction. In commercial citrus orchards co-infection of Citrus tristeza virus (CTV) and viroids ... -
The use of high-through put small RNA sequencing reveals differentially expressed microRNAs in response to aster yellows phytoplasma-infection in Vitis vinifera cv. Chardonnay
(Public Library of Science, 2017)Phytoplasmas are cell wall-less plant pathogenic bacteria responsible for major crop losses throughout the world. In grapevine they cause grapevine yellows, a detrimental disease associated with a variety of symptoms. The ... -
Assessing the control potential of aldicarb against grapevine phylloxera
(South African Society for Enology and Viticulture, 1992)Aldicarb 15 G soil treatments in vineyards were evaluated for their phylloxera control potential. A post-harvest application was made on single vines and phylloxera populations on roots were quantified using a washing and ... -
African origin for Madagascan dogs revealed by mtDNA analysis
(Royal Society, 2016)Madagascar was one of the last major land masses to be inhabited by humans. It was initially colonized by Austronesian speaking Indonesians 1500–2000 years ago, but subsequent migration from Africa has resulted in approximately ... -
Species identification and comparative population genetics of four coastal houndsharks based on novel NGS-mined microsatellites
(Wiley Open Access, 2017)The common smooth-hound (Mustelus mustelus) is the topmost bio-economically and recreationally important shark species in southern Africa, western Africa, and Mediterranean Sea. Here, we used the Illumina HiSeq™ 2000 ... -
Involvement of Fenton chemistry in rice straw degradation by the lignocellulolytic bacterium Pantoea ananatis Sd-1
(BioMed Central, 2016)Background: Lignocellulolytic bacteria have revealed to be a promising source for biofuel production, yet the underlying mechanisms are still worth exploring. Our previous study inferred that the highly efficient ... -
Genomic and secretomic insight into lignocellulolytic system of an endophytic bacterium Pantoea ananatis Sd-1
(BioMed Central, 2016)Background: Exploring microorganisms especially bacteria associated with the degradation of lignocellulosic biomass shows great potentials in biofuels production. The rice endophytic bacterium Pantoea ananatis Sd-1 with ... -
Evidence for water deficit-induced mass increases of raffinose family oligosaccharides (RFOs) in the leaves of three Craterostigma resurrection plant species
(Frontiers Media, 2015-07)The leaves of the resurrection plant Craterostigma plantagineum accumulate sucrose during dehydration, via a conversion from the unusual C8 ketose-sugar 2-octulose. However, raffinose family oligosaccharides (RFOs) have ...
