  • Data management system developed by Aarhus University, Denmark in collaboration with BGRI / FAOSits on top of a centralized Crop Problem Dbase – currently holds survey and pathotype data but will be expanded to include trap nursery and molecular diagnostic data. Flexible dbase capable of holding all 3 rust diseases – expansion in progress to incorporate yellow rust data.Toolbox permits: user management (different access / permission levels); on-line data entry; data quality control and publishingOutputs: Series of data-base driven graphical tools. Currently: survey mapping, pathotype frequencies and distributions over time. Additional tools planned for the future. All outputs as iframes so seemelessly embedded in external websites eg Rust SPORE at FAO.Standard data export / exchange permitting direct connection to external applications eg RustMapper at CIMMYT.
  • Transcript of "Tracking the wheat rust pathogens"

    1. 1. Dedication: Sam Kilonso (1964-2012) A man who welcomed everyone with a huge smile and a warm heart. Someone who made a huge contribution to rust surveillance work in Kenya.
    2. 2. Tracking the wheat rust pathogens D. P. Hodson, J. Grønbech-Hansen, P. Lassen, Y. Alemayehu, J. Arista, K. Sonder, P. Kosina, P.Moncada, K. Nazari, R. F. Park, Z. A. Pretorius, L. J. Szabo, T. Fetch and Y. Jin
    3. 3. Outline
    4. 4. Global Rust Monitoring: TheCatalyst – “Ug99” Isolate Ug99 – race TTKSK Unique virulence. Large % of commercial cultivars susceptible Realization that we need a global system to detect and monitor new, virulent races of wheat rusts
    5. 5. What is Ug99? Not a single entity “Ug99 Race group” 8 known members the group of Pgt races sharing almost identical molecular fingerprints to the original Ug99 isolate (race TTKSK). Most races in the group have virulence to Sr31, but Sr31-avirulent progenitors/relatives are also included.
    6. 6. The Surveillance Network  Data poor to an increasingly data rich environment  2007 countries n = 2; 2012 countries n = 27  Contributing surveys cover about 20% of global wheat area2005 2012 An outstanding example of global collaboration
    7. 7. Status: Pathogen Monitoring 1999: race TTKSK “Ug99” identified 2012: 8 members of the Ug99 race group – we know what they are and where they are! Spread throughout Africa and into Asia. Further spread very Ug99 race group is now in 11 countries likely
    8. 8. Changing Pathogen Populations2009/2010 DataRace TTKSK (original “Ug99” [red]) only predominates in EthiopiaOther Ug99 race group races predominate e.g., Sr24 variants
    9. 9. Keeping track of “lots” of dataData management system – The Wheat Rust Toolbox (also South Asia Toolbox) – collaboration with GRRC and SathguruSurveys: 27 countries, 9000+ recordsPathotypes: 21 countries, 1075 isolates

    11. 11. Registered User content –Toolbox Adding valueOn-line data entry (or smartphone / tablet app)Quality controlAutomatic, rich content, country-specific graphical display out (tables, graphs, maps)
    12. 12. Public Information Systems:WWW Rust Tracker.org Aim:  Single source of up-to-date information for all global wheat rust monitoring activities Content:  Country-specific info: 38 countries  Dynamic tools – Wheat Rust Toolbox driven www.rusttracker.cimmyt.org
    13. 13. Rust Tracker.org / Toolbox –Platform for all rustsAll examples show Yellow RustIncreased focus on other rusts

    15. 15. New activities Epidemiological modelling + early warning (Cambridge Uni. / Rothamsted) Expanded focus on other rusts More integrated tools and data sets (Molecular data, trap nursery, Barberry surveys, Screening nursery……) SMS networks – extension / farmer early warning systems (FAO)
    16. 16. Summary Now have a fully operational global disease monitoring system. Surveillance and monitoring network, covering 35 countries and a large proportion of the developing world wheat area Tracked the spread and status of important stem rust races e.g., “Ug99 race group". A robust and functional data management system - the Wheat Rust Toolbox - is now in place. Global collaboration is ensuring that key databases are shared and being integrated into different information platforms.
