Direct transformation of maize (Zea mays L.) tissue using electroporation and particle bombardment, and regeneration of plantlets.
(1996)Please open electronic version for Abstract. -
Dynamics of the glutathione/glutaredoxin system.
(2014)The glutathione/glutaredoxin system is made up of glutaredoxins, glutathione (GSH) and glutathione reductase (GLR). Glutaredoxins, which are involved in essential cellular functions such as DNA synthesis, iron metabolism ... -
The dynamics of thioredoxin-dependent reactions.
(2014)The thioredoxin system, comprising thioredoxin (Trx), thioredoxin reductase (TrxR) and NADPH, is present in most organisms from prokaryotes to eukaryotes. The system plays a central role in the redox regulation of several ... -
Elucidation of gene function using RNA interference in a cancer cell culture model.
(2011)RNA interference (RNAi), mediated by small interfering RNA (siRNA), has emerged as a powerful tool for elucidating gene function and also holds great potential for the treatment of acquired and inherited diseases. The ... -
The elucidation of the possible mechanism of vancomycin-resistance in selected streptococcal and enterococcal species.
(2005)Three Streptococcal strains: S. milleri P213, S. milleri P35 and S. milleri B200 and three enterococcal strains: E. faecalis 123, E. faecalis 126 and E. faecium were used to test for vancomycin resistance. Two strains were ... -
Estimation of genetic and demographic parameters of extensively raised chicken populations using genome-wide single nucleotides polymorphism (SNP) data.
(2015)Village chicken populations are raised under a farming system that faces a number of challenges such as small flock size, lack of animal performance and pedigree records, lack of proper husbandry and poorly defined and ... -
Estimation of genetic variation and marker identification in black wattle (Acacia mearnsii De Wild) with RAPD fingerprinting.
(2004)No abstract available. -
Fingerprinting of full and half-sib black wattle (Acacia mearnsii) progenies using Random Amplified Polymorphic DNA (RAPD).
(2005)Black wattle (Acacia mearnsii), which belongs to the genus Acacia, is one of the many species of trees or hardwoods grown commercially in South Africa. Black wattle is a species indigenous to Australia and was introduced ... -
Genetic characterization of resistance and virulence genes in Enterococcus species from animal isolates in Durban.
(2018)Misuse of antimicrobials in animal agriculture has given rise to strains of bacteria that are resistant to multiple antibiotics. Enterococci bacteria have emerged among such antibiotic-resistant strains of bacteria and ... -
Genetic diversity of populations of a Southern African millipede, Bicoxidens flavicollis (Diplopoda, Spirostreptida, Spirostreptidae)
(2018)The African millipede genus Bicoxidens is endemic to Southern Africa, inhabiting a variety of regions ranging from woodlands to forests. Nine species are known within the genus but Bicoxidens flavicollis is the most dominant ... -
Genetic evaluation of South African indigenous chickens for disease resistance.
(2015)An alternative standard disease control method would be selective breeding in order to increase disease resistance. To set up marker assisted selection programmes, knowledge of the genetic diversity of the chickens is ... -
Genetic identification of kikuyu grass (Pennisetum clandestinum) cultivars by RAPD and ISSR techniques.
(2015)Kikuyu grass (Pennisetum clandestinum), originally from tropical and subtropical African countries, is one of the most important pasture grasses in the higher rainfall regions of South Africa (of utmost importance in ... -
The glutaredoxin/glutathione post-stress recovery system is dependent on the availability of glutathione in the cell.
(2020)The cellular response to oxidative stress involves three interconnected processes: reactive oxygen species detoxification, adaptation and repair. Glutathionylation is an adaptive response in which glutathione binds to ... -
Identification of tissue specific differential methylation in human body fluids and its potential application in forensics.
(2015)In forensic investigations, human biological traces have great potential to serve as strong evidence in placing a suspect at the scene of a crime. In cases where activities leading to the deposition of an individual’s ... -
Individual identification and parentage analysis of Struthio camelus (ostrich) using microsatellite markers.
(2005)Ostrich (Struthio camelus) breeding is a well-developed industry in South Africa. However, successful genetic management has yet to be implemented. Parentage in colony breeding ostriches is unknown, where for a given ... -
Induction of polyploidy in Eucalyptus species and interspecific hybrids.
(2008)A large sector of the forestry industry of South Africa comprises Eucalyptus species, covering approximately 49% of the forestry plantation area. Polyploidy induction has become an attractive tool to increase yield and ... -
The influence of the leader sequence on antimicrobial activity of Leucocin A, an antilisterial bacteriocin produced by Leuconostoc gelidum UAL187-22.
(2008)Bacteriocin leader pepides are currently receiving much attention due to their possible functions. It is predicted that these leaders prevent cytoplasmic toxicity within the producer organism by rendering the bacteriocin ... -
The inhibition of Fusarium oxysporum f.sp. cubense race 4 by Burkholderia cepacia.
(1997)Inhibition of Fusarium oxysporum f. sp. cubense race 4 by Burkholderia cepacia was evident when grown on various media (TSA, PDA, PSA, YM, KMB, PPM, NYGA, LA) with different carbon sources and under various pH and ... -
An investigation into the heritability of commercially important traits in a sugarcane population under dryland conditions.
(1995)Inheritance studies have previously been undertaken at the South African Sugar Association Experiment Station (SASEX) under irrigated conditions. Since most sugarcane is grown in South Africa under dryland (raingrown) ... -
Investigation into the relationship between leptin genotypes, body condition and carcass traits of Nguni and Hereford cattle.
(2010)Leptin, a 16 (kilo Dalton) kDa hormone secreted predominantly by white adipocytes, regulates reproduction, energy intake and expenditure, and is involved in immune system function. Previous studies have identified associations ...
