ARC-GCI plant breeding and biotechnology We focus mainly on the development and application of molecular markers for marker assisted breeding in soybean, drybean, peanut and maize. Fingerprinting of maize and sunflower lines are done with fluorescently labeled SSR markers on routine basis utilizing automated electrophoresis with an ABI3130xl genetic analyzer. Other techniques used include AFLP and microsatellite analysis utilizing silverstaining of PAGE gels. SCARs are developed by isolation of bands from the stained gels, amplification, purification and cloning of the fragments.  Sequencing is done in-house.  New primers are developed from sequence information. A study on identification of molecular markers for use in marker assisted selection in soybean was successfully completed with two markers converted from AFLP fragments to SCAR markers, and one RFLP marker linked to root-knot nematode resistance (Meloidogyne javanica). Markers linked to resistance to Meloidogyne incognita were also successfully developed. Markers were also developed for rust resistance in dry bean and several markers are used for marker assisted selection in the breeding program on routine basis.  The different species of root-knot nematode prevalent in South Africa are identified with PCR on a routine basis. Fungal isolates are identified through sequencing analysis. Statistical analysis of molecular data is done with NTSYSpc, STATGRAPHICS, Powermarker, MapManager, MAPMAKER/EXP, MAPMAKER/QTL and QTL Cartographer.

Orbivirus Research Group My research focuses on the moleclar biology of African horse sickness virus, I am specifically interested in aspects relating to virulence and pathogenesis. At the moment I am leading an ivestigation into the mechanisms of release of African horse sickness virus (AHSV) from insect and mammalian cells, proposed to be mediated by nonstructural protein NS3. This involves investigsting the intercellular trafficking, interaction with host cellular components and release of AHSV particles from infected mammalian and insect cells; comparing the regulation of gene expression of parental and reassortant AHSV strains and the effect thereof on mammalian and insect host cells; and characterising the functional domains of ASHV NS3 that determines its subcellular localisation, trafficking and cytotoxicity by using recombinantly expressed NS3 protein as antigen display systems in vaccine development Genetics van Staden, Vida
Evolutionary Genetics Group I am primarily interested in how micro evolutionary processes scale up to result in macro evolutionary patterns. To study this question I use a combination of evolutionary modelling and applying it to data collected from various organisms. In South Africa we use the Ficus microcosm, which includes fig wasps, fungus, nematodes and mites coevolving in the same niche to test hypotheses. My research is primarily concerned with phenotypes (phenomics) – a somewhat neglected field in the “omics” age and the eventual goal is to map genotypic variation to phenotypic variation in this system. Currently we know very little of the genetics of these organisms, but are looking into newer techniques, such as RAD sequencing in order to sequence large parts of their genomes, as well as to quantify genetic variation at the SNP level Genetics Pienaar, Jason

Evolutionary Medicine Unit The Evolutionary Medicine Unit (EMU) uses an integrated and collaborative approach to tackle fundamental questions in molecular and cellular evolution, and applies these advances to our understanding of human disease. Evolutionary biology is experiencing a period of rapid growth with major conceptual and experimental advances being made (see “Do we need an extended evolutionary synthesis” by M Pigliucci, 2007). In addition, the value of using evolutionary principles to investigate disease is becoming apparent (see “The great opportunity: Evolutionary applications to medicine and public health” by RM Nesse and SC Stearns, 2007).Our work crosses the artificial boundaries of traditional disciplines. We use whatever approaches are appropriate, and have been known to develop new ones! Active collaborations with scientists in diverse fields and at other universities make this a highly dynamic, stimulating research group. Researchers with backgrounds in molecular and cell biology, ecology, evolution, biochemistry, bioinformatics, computational biology and medicine may find a home here. EMU occupies a newly renovated laboratory with access to all the basic equipment required for molecular biology research and is affiliated to the Department of Molecular Medicine and Haematology at the University of the Witwatersrand, Johannesburg, South Africa EMU researchers investigate the molecular and cellular basis for evolutionary transitions and increase in biocomplexity, including the origins of the genome, multicellularity and programmed cell death. This is essentially a study of the molecular evolution of cooperation. Insights gained are often applied to our understanding of human disease. The volvocine algae are often used as a model system (for more information see the Volvocales Information Project at; however other organisms, tissues and viruses are used in our projects.

Pest and disease problems on forest trees (FABI) My research interests are focused in the broad area of forest biotechnology. More specifically, my research group studies various aspects of pathogens, particularly fungi that are important to the forestry industries of South Africa and other countries of the world. We are particularly interested in those fungi that cause diseases of trees, degrade timber or that are potentially valuable in various aspects of the pulping process and in the production of industrially valuable compounds. We also have active projects dealing with insect pests in plantations. My research programme falls under the umbrella of the Tree Protection Cooperative Programme (TPCP) that is a cooperative venture between the University of Pretoria and all forestry companies in South Africa including Hans Merensky, Global Forest Products, NCT, CTC, TWK, Sappi, Mondi, Komatiland Forests, Mountain to Ocean, SA Forestry, the Department of Water Affairs and Forestry and the Institute for Commerical Forestry Research. As such, the team bears the responsibility for all forest protection issues in South Africa, covering an area of about 1.5 million hectares of plantation.Some of the fungi of particular interest to our group and that are the subject of intensive study, both at the ecological and molecular level are the notorious tree pathogens Chrysoporthe austroafricana (anamorph Chrysoporthella hodgesiana, ex Cryphonectria cubensis) that causes a serious stem canker disease of Eucalyptus, Diplodia pinea (Sphaeropsis sapinea) that devastates pine plantations after hail and species of Ceratocystis that cause a serious wilt diseases of trees, the pitch canker fungus Fusarium circinatum, Mycosphaerella spp. that infect leaves and needles, Botryosphaeria spp. that cause stem cankers, Cylindrocladium spp. that cause leaf blight , Armillaria root rot, Eucalyptus rust and others. Species of Ophiostoma (a group that includes the Dutch elm disease agent) have also been the subject of investigation for numerous years and are of special interest, not only for their role as tree pathogens but also for their potential value in pulp production and monoterpene bioconversions. Amongst the insects of greatest interest to me are the Sirex wood wasp (Sirex noctilio) and a wide range of bark beetles (Coleoptera: Scolytidae) that infest conifers.I am involved in a wide range of research projects both in South Africa and elsewhere in the world. These include those linked to the TPCP (see the TPCP section of this web site) and funded by the South African Forestry Industry together with various associated Government grants, international projects including those with the Chinese, Norwegian, Australian and Swedish Governments, and projects with forestry companies in Latin America and South East Asia.For further information please refer to website.

Plant heat and disease resistance The plant innate immune response is mediated by resistance genes and involves activation of programmed cell death programs. These responses are essential to ensure continued survival of plants against the onslaught of various pathogens. However, heat-related abrogation of disease resistance is a well established phenomenon, and has been related to changes in defence gene expression. Some of these alterations include decreased salicylic-acid accumulation, PR-protein expression and phenyl-propanoid expression, all events shown to be necessary for the establishment of resistance to recognized pathogens. Furthermore, it has been (Cronje, Weir et al. 2004) shown that induced apoptotic-related events in plants, including perturbations in mitochondria, externalization of phosphatidylserine on the plasma membrane and DNA fragmentation, are negatively correlated with Hsp70, a 70 kDa protein induced by heat shock and involved in thermotolerance and protection against oxidative stress. However, the interaction between these two mutually exclusive events (cell death vs. cell survival) are not understood in plants, and given the complexity of both these processes, it is essential to fully understand these before strategies are devised to transform plants. These net changes occurring in the transcriptome of plants during simultaneous heat treatments and pathogen exposure can be investigated comprehensively with microarrays. Exploring the precise function of the differentially expressed genes analysed by this technique will provide insights into heat-related changes to defence responses. Ultimately, this knowledge will aid the development of strategies to transform/genetically engineer plants that are both heat- and disease resistant. Plant biosciences Walters, John
