Population genetic structure and demographical history of South African abalone, Haliotis midae, in a conservation context
(Stellenbosch : University of Stellenbosch, 2009-03)ENGLISH ABSTRACT: South African abalone, Haliotis midae, has been the subject of major concern regarding its survival and conservation over the last decade or more. Being the only one of five endemic species with commercial ... -
Population genetics of Galeorhinus galeus, Carcharhinus brachyurus and Rhinobatos annulatus- implications for regional fisheries and elasmobranch conservation
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT: Elasmobranchs (sharks, skates and rays) are highly exploited world-wide and more vulnerable than most teleosts due to their life history traits (e.g. late age at maturity, low fecundity and slow growth). ... -
Reproduction of the South African abalone, Haliotis midae
(Stellenbosch : Stellenbosch University, 2011-12)ENGLISH ABSTRACT: Currently, South African aquaculture is dominated by the cultivation of Haliotis midae, which is estimated as the most lucrative sector of the industry, with 934 t being export in 2008, totalling an income ... -
Signatures of selection in natural and cultured Abalone (Haliotis midae) : a population genomics study
(Stellenbosch : Stellenbosch University, 2013-03)ENGLISH ABSTRACT: The South African abalone, Haliotis midae, commonly known as perlemoen, is an economically important gastropod mollusc. Historically, this species maintained a lucrative fisheries sector; however with ... -
Small RNA profiling of grapevine leafroll-associated virus 3 infected grapevine plants
(Stellenbosch : Stellenbosch University, 2016-12)ENGLISH ABSTRACT: One of the most important viral diseases of grapevine worldwide is grapevine leafroll disease (GLD). A number of viruses from the family Closteroviridae have been associated with this disease, though Grapevine ... -
Small RNA profiling of virus-infected apple plants
(Stellenbosch : Stellenbosch University, 2014-12)ENGLISH ABSTRACT: Apple stem grooving virus (ASGV) is globally associated with latent infection in commercial apple trees. Little is known about this plant-‐virus interaction. This study made use of next-‐generation ... -
Tagging and mapping of prominent structural genes on chromosome arm 7DL of common wheat
(Stellenbosch : Stellenbosch University, 2001-12)ENGLISH ABSTRACT: Chromosome arm 7DL of common wheat carries genes for agronomically important traits such as leaf rust, stem rust, Russian wheat aphid and eye spot resistance. Some of these genes occur on introgressed ... -
Trehalose and carbon partitioning in sugarcane
(Stellenbosch : University of Stellenbosch, 2005-12)The current understanding of the regulation of sucrose accumulation is still incomplete even though many scientists have investigated this subject. Components of trehalose metabolism have been implicated in the regulation ... -
Unravelling the mystery of the shark genus Mustelus in southern Africa using a multidisciplinary approach
(Stellenbosch : Stellenbosch University, 2017-12)ENGLISH ABSTRACT: Multidisciplinary approaches have previously offered some alternative innovative ways of addressing classical ecological questions while providing novel insights into behaviour and biology of elasmobranch ... -
Virus induced gene silencing for the study of starch metabolism
(Stellenbosch : University of Stellenbosch, 2010-03)ENGLISH ABSTRACT: Virus Induced Gene Silencing (VIGS) was optimized to allow for the study of starch metabolism. The plastidial inorganic pyrophosphatase gene, for which a mutant has never been identified, was studied ...
