Session 2: Scandinavian Partnerships that have Advanced the BGRI
Denmark's investment in the Global Rust Reference Center (GRRC)
Outline • Facilities: People, space, equipment and
ressources • GRRC aims and mission
- Management: surveillance, ’early-warning’, on-line dissemination of results, detection and maintenance of pathogen genetic resources, etc.
- Training: International researchers and students - Research: epidemiology, evolutionary biology, genetics

Wheat rust quarantine facility
Green house & lab space, GRRC, 2012-13 • 5 quarantine zones
(8-12 cabins/zone) • 2 rust labs • 1 molecular lab
Expanding quarantine facilities November 2013
Expanding quarantine facilities March 2014: Two new zones ready (1st April)
Expanding quarantine facilities March 2014: Additional new rust lab ready
N2 storage of live wheat rust isolates ~ 8,500 samples from recent years and ~ 5,000
samples from the past (”Stubbs collection”)

GRRC aims and mission: Global Rust Reference Center (GRRC) established in 2008 on request from CIMMYT, ICARDA and the BGRI Management (surveillance, ’early-warning’, genetic stock isolates) • Getting alive pathogen samples: Quarantine facility which
can recieve live samples of wheat rust from any country year round (in collaboration with national and regional labs)
• Purify and maintain genetic stocks: Keep pathogen genetic ressources to assist resistance breeding and research
• Data management: Establish efficient (online) tools • Training of students and cientists in wheat rust pathology

Research • Understanding pathogen spread and evolution at regional and
global scales, genetics of virulence, host-pathogen interactions at the molecular level, improved tools for assessment of the pathogen (and host) phenotype
The challences for understanding ’global’ spread and dynamics of wheat rust fungi
Improved techniques for assessment of quantitative traits

Conclusions • Global Rust Reference Center is running and expanding –
current emphasis on yellow (stripe) rust and stem rust
• Significant new investments since start in 2008 (Danish & international funding of research, and Aarhus University investments in facilities)
• Isolate stock collections expanding
• Wheat Rust Toolbox provide rapid online dissemination of results => feed into several other “information systems”
• New methodologies for both host and pathogen phenotyping in progress (quantitative level)
• The wheat rusts: Sustained efforts needed – recent improvements may quickly become lost
