Association analysis of two single-nucleotide polymorphisms of the RELN gene with autism in the South African population
(Mary Ann Liebert, Inc., 2013)BACKGROUND: Autism (MIM209850) is a neurodevelopmental disorder characterized by a triad of impairments, namely impairment in social interaction, impaired communication skills, and restrictive and repetitive behavior. A ... -
Balancing redox cofactor generation and ATP synthesis: key microaerobic responses in thermophilic fermentations
(Wiley, 2013)Geobacillus thermoglucosidasius is a Grampositive, thermophilic bacterium capable of ethanologenic fermentation of both C5 and C6 sugars and may have possible use for commercial bioethanol production [Tang et al., 2009; ... -
Brown rot-type fungal decomposition of sorghum bagasse: variable success and mechanistic implications
(Hindawi Publishing Corporation, 2018)Sweet sorghum is a promising crop for a warming, drying African climate, and basic information is lacking on conversion pathways for its lignocellulosic residues (bagasse). Brown rot wood-decomposer fungi use carbohydra ... -
Capacity to control oxidative stress-induced caspase-like activity determines the level of tolerance to salt stress in two contrasting maize genotypes
(Springer, 2013)The response of two maize (Zea mays L.) genotypes, named GR (salt-tolerant) and SK (salt-sensitive), to salt stress (150 mM NaCl) was investigated under controlled environmental growth conditions. Genotype SK experienced ... -
A decade of plant proteomics and mass spectrometry: Translation of technical advancements to food security and safety issues
(Wiley, 2013)Tremendous progress in plant proteomics driven by mass spectrometry (MS) techniques has been made since 2000 when few proteomics reports were published and plant proteomics was in its infancy. These achievements include ... -
Diversity of dsDNA viruses in a South African hot spring assessed by metagenomics and microscopy
(MDPI, 2017)The current view of virus diversity in terrestrial hot springs is limited to a few sampling sites. To expand our current understanding of hot spring viral community diversity, this study aimed to investigate the first ... -
Factors influencing pigment production by halophilic bacteria and its effect on brine evaporation rates
(Wiley, 2018)The disposal of reject brine, a highly concentrated waste by-product generated by various industrial processes, represents a major economic and environmental challenge. The common practice in dealing with the large ... -
Genetic variation and population structure of Botswana populations as identified with AmpFLSTR Identifiler short tandem repeat (STR) loci
(Nature Publishing Group, 2017-07-28)Population structure was investigated in 990 Botswana individuals according to ethno-linguistics, Bantu and Khoisan, and geography (the nine administrative districts) using the Identifiler autosomal microsatellite markers. ... -
Genome sequences of three vaccine strains and two wild-type canine distemper virus strains from a recent disease outbreak in South Africa
(American Society for Microbiology, 2017)Canine distemper virus causes global multihost infectious disease. This report details complete genome sequences of three vaccine and two new wild-type strains. The wild-type strains belong to the South African lineage, ... -
Identification and profiling of salinity stress-responsive proteins in Sorghum bicolor seedlings
(Elsevier, 2012)Sorghum bicolor, a drought tolerant cereal crop, is not only an important food source in the semi arid/arid regions but also a potential model for studying and gaining a better understanding of the molecular mechanisms ... -
Inhibition of bacteria associated with wound infection by biocompatible green synthesized gold nanoparticles from South African plant extracts
(MDPI, 2017)Unlike conventional physical and chemical methods, the biogenic synthesis of gold nanoparticles (GNPs) is considered a green and non-toxic approach to produce biocompatible GNPs that can be utilized in various biomedical ... -
Inhibition of NOS- like activity in maize alters the expression of genes involved in H2O2 scavenging and glycine betaine biosynthesis
(Nature Publishing Group, 2018)Nitric oxide synthase-like activity contributes to the production of nitric oxide in plants, which controls plant responses to stress. This study investigates if changes in ascorbate peroxidase enzymatic activity and ... -
INPPO actions and recognition as a driving force for progress in plant proteomics: Change of guard, INPPO update, and upcoming activities
(Wiley, 2013)The International Plant Proteomics Organization (INPPO) is a non-profit organization whose members are scientists involved or interested in plant proteomics. Since the publication of the first INPPO highlights in 2012, ... -
Mapping and characterisation of the sorghum cell suspension culture secretome
(Academic Journals, 2011)Here we reported the first secretomic study of sorghum (Sorghum bicolor), a naturally drought tolerant cereal crop. In this study, we used a gel-based proteomic approach in combination with mass spectrometry to separate ... -
Meat trade: need for international standardization?
(Elsevier, 2013)Extensive substitution and undeclared species have been recently detected in meat products in South Africa, Europe and Asia. Here we review the methodologies utilized in the identification of species in red meat products ... -
Modulation of antioxidant enzyme activities and metabolites ratios by nitric oxide in short-term salt stressed soybean root nodules
(Elsevier, 2013)Several abiotic factors cause molecular damage to plants either directly or through the accumulation of reactive oxygen species such as hydrogen peroxide (H2O2). We investigated if application of nitric oxide (NO) donor ... -
Molecular adaptation mechanisms employed by ethanologenic bacteria in response to lignocellulose-derived inhibitory compounds
