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, ... -
One-pot synthesis and characterization of InP/ZnSe semiconductor nanocrystals
(Elsevier, 2013)We report on the one-pot synthesis of InP/ZnSe quantum dots (QDs) using a precursor-based colloidal synthesis in a noncoordinating solvent environment. The structural and optical studies were carried out on the as-prepared ... -
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 ... -
Nitric oxide affects salt-induced changes in free amino acid levels in maize
(Elsevier, 2013)It was assumed that salt-induced redox changes affect amino acid metabolism in maize (Zea mays L.), and this influence may be modified by NO. The applied NaCl treatment reduced the fresh weight of shoots and roots. This ... -
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 ... -
The use of ultraviolet radiation as a non-thermal treatment for the inactivation of alicyclobacillus acidoterrestris spores in water, wash water from a fruit processing plant and grape juice concentrate
(CUT Free State, 2013)Alicyclobacillus acidoterrestris is a non-pathogenic, spore-forming bacterium that can survive the commercial pasteurisation processes commonly used during fruit juice production. Surviving bacterial endospores germinate, ... -
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 ... -
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 ... -
The air quality perceptions of the residents of Bayview, Mossel Bay
(NACA, 2014)Background: In developing countries, it often occurs that little attention is given to air pollution emissions due to a lack of proper town planning, household combustion processes, energy production and the continuous ... -
Genetic polymorphisms and haplotypes of the organic cation transporter 1 gene (SLC22A1) in the Xhosa population of South Africa
(Brazilian Society of Genetics, 2014)Human organic cation transporter 1 is primarily expressed in hepatocytes and mediates the electrogenic transport of various endogenous and exogenous compounds, including clinically important drugs. Genetic polymorphisms ... -
Response of soybean nodules to exogenously applied caffeic acid during NaCl-induced salinity
(Elsevier, 2015)affeic acid acts as an antioxidant to scavenge reactive oxygen species, but its influence on plant responses to abi- otic stresses is only partially understood. Here, we investigated the influence of exogenously applied ... -
Identification and characterization of a heat-inducible Hsp70 gene from Sorghum bicolor which confers tolerance to thermal stress
(Springer, 2015)This study describes the first detailed molecular characterization of the heat shock protein 70 (Hsp70) gene from Sorghum bicolor, MN1618 designated as SbHsp70-1. The full-length cDNA of SbHsp70-1 consists of 2524 bp ... -
Impact of metagenomic DNA extraction procedures on the identifiable endophytic bacterial diversity in Sorghum bicolor (L. Moench)
(Elsevier, 2015)Culture-independent studies rely on the quantity and quality of the extracted environmental metagenomic DNA (mDNA). To fully access the plant tissue microbiome, the extracted plant mDNA should allow optimal PCR applications ... -
The production of hydrogen through the use of a 77 wt% Pd 23 wt% Ag membrane water gas shift Reactor
(Elsevier, 2016)Hydrogen as an energy carrier has the potential to decarbonize the energy sector. This work presents the application of a palladium-silver (PdeAg) membrane-based reactor. The membrane reactor which is made from PdeAg film ... -
GlobalFiler® express DNA amplification kit in South Africa: Extracting the past from the present
