  4. Vision To create a world class biotechnology platform to lead research in agriculture in Africa

  5. Mission • To provide excellent biotechnology research and service platforms to enhance food security and promote agriculture in Africa • To provide biotechnology tools in support of all areas of research and development within the mission of the ARC • To create a world class research and innovation environment to attract the best researchers and students • To train the next generation of specialist researchers in cutting edge biotechnologies

  6. The Objectives • To create Service, Development and Research structures in support of and in collaboration with all ARC Institutes and external partners • To address the needs of commercial and emerging agriculture nationally and continentally • To train new researchers and postgraduates at the highest level • To compete at the top level internationally • To have the “best in class” resources for modern biotechnology • To raise funds external funding, nationally and internationally

  7. Service and Research Facilities Model Technology Focus of Unit Key technologies being performed with the sub-platform as services to research groups and pipelines with the ARC and to outside clients Unit Each sub-platform to have a development group responsible for introducing new technology and applications into the core services Core Services Internal Research teams, lead by SR, SpR, PR level scientists. With MSc, PhD and PD level students as the major part of each team. Primarily externally funded with competitive grants Development group Research teams within platform Research teams at Institutes External Research teams, led by SR, SpR, PR level scientists.MSc, PhD and PD level students are the major part of each team. Primarily externally funded with competitive grants

  18. Focused Genotyping

  19. Custom Genotyping

  20. The Rosaceae – Fruits, Nuts and Flowers

  21. RosaceaeBeadChips • RoscaeaeBeadChip • SA and NZ working in collaboration withRosBREED • Using around 9,000 SNPs per species • Apple, Peach, Cherry, Strawberry • SNPs are from founders of major breeding programs and novel cultivars • Optimised for cultivated populations as opposed to wild crosses • Available March 2011

  22. Customize HiScanSQ To Meet Your Needs – Now or Later SPLs: Samples HumanOmniExpress 12 sample BeadChips. Throughput varies by BeadChip For illustration purposes only – consult your rep to discuss your expected sample throughput. Assumptions: 6 Gb/day sequencing output. Manual sample processing: 1 HiScan, 0 Autoloader2.x, 0 Tecan liquid handling robots, 5 day work week; 2 FTEs. Automated sample processing: 5 day work week; 24 hour scanning powered by 1 AutoLoader2.x, 1 Tecan liquid handling robot.

  23. Predictions Cost per data point will continue dramatic reduction for both Arrays and Sequencing Sequencing output will scale quickly Array content and complexity will increase significantly Sample numbers for projects will grow Sequencing and array solutions will continue to co-exist and complement Cost, Complexity and Complementary Solutions

  24. ARC Biotech Platform ImplementationThe First Genomes • First genome sequencing: March 2011 • Apple, pear, aphid, tick, amaranth, heartwater, avian paramyxovirus • (15 apple genomes resequenced in 2010) • First major genotyping experiments, from May 2011 • Apple (RosBREED - USA) • Peach (ARC) • Cattle (ARC) • Sheep (US, ARC)

  25. Agric-Biotech Smart Tools • Rapid characterization of novel genomes (plants, animals, pathogens) • Gene expression and genotyping technologies • Molecular Breeding for rapid crop and animal improvement: • Genome-wide selection • Marker assisted selection • Tissue Culture and micro-propagation of plants • Cis-genesis and Genome Engineering • Reproductive biotechnologies • Vaccines, therapeutic proteins, diagnostics

  26. Impact on Agricultural Research and Development • Faster, better, more selective and more sensitive: • Plant Breeding • Animal Breeding • Cultivar identification (PBR) • Pathogen identification • Diagnostics • Vaccine development • Vaccine quality control and safety • Bringing better crops and animals to farmer at all scales • Bringing novel, cash generating, sustainable products to the market • Increasing food and income security

  27. ARC: BP – the 5 year horizon • By 2015, The ARC Biotech Centre will be a vibrant Agri-Biotech institution – a Centre of Excellence in research, training and services with National and International standing • Regional integration of services and research • Training of new generation of researchers and postgraduates • Implementation of high throughput systems for applied and basic research • Increased funding and collaborative opportunities
