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 ... -
Phylogenomic analysis reveals deep divergence and recombination in an economically important grapevine virus.
(Public Library of Science, 2015)The evolutionary history of the exclusively grapevine (Vitis spp.) infecting, grapevine leafroll-associated virus 3 (GLRaV-3) has not been studied extensively, partly due to limited available sequence data. In this study ... -
Diverse exopolysaccharide producing bacteria isolated from milled sugarcane : implications for cane spoilage and sucrose yield
(Public Library of Science, 2015)Bacterial deterioration of sugarcane during harvesting and processing is correlated with significant loss of sucrose yield and the accumulation of bacterial polysaccharides. Dextran, a homoglucan produced by Leuconostoc ... -
Next-generation sequencing for virus detection : covering all the bases
(BioMed Central, 2016-06)Background: The use of next-generation sequencing has become an established method for virus detection. Efficient study design for accurate detection relies on the optimal amount of data representing a significant portion ... -
Extending the sRNAome of Apple by next-generation sequencing
(Public Library of Science, 2014-04)The global importance of apple as a fruit crop necessitates investigations into molecular aspects of the processes that influence fruit quality and yield, including plant development, fruit ripening and disease resistance. ... -
Abiotic stress-induced accumulation of raffinose in Arabidopsis leaves is mediated by a single raffinose synthase (RS5, At5g40390)
(BioMed Central, 2013)Background: The sucrosylgalactoside oligosaccharide raffinose (Raf, Suc-Gal1) accumulates in Arabidopsis leaves in response to a myriad of abiotic stresses. Whilst galactinol synthases (GolS), the first committed enzyme ... -
High-throughput sequencing reveals small RNAs involved in ASGV infection
(BioMed Central, 2014)Background : Plant small RNAs (sRNAs) associated with virulent virus infections have been reported by previous studies, while the involvement of sRNAs in latent virus infection remains largely uncharacterised. Apple trees ...
