The Warrior race group spreads in Europe

New cereal varieties will need less pesticide

Scientists from Aarhus University and commercial breeders and leading foreign research institutions will in partnership develop new varieties of wheat that are resistant to a number of devastating fungal diseases. The project has been granted 17 million Danish kroner from Innovation Fund Denmark.

Yellow rust in Europe: The Warrior race group has spread to new areas in 2014

New results from GRRC show that isolates of the Warrior race group were present in high frequencies at many epidemic sites in Europe in 2014. Isolates of this race group were detected on many varieties of both wheat and triticale, which confirm a high level of aggressiveness of such isolates. New race data for 2014 were uploaded on 23 December…

New article: Sexual structures and recombination of the wheat rust fungus Puccinia striiformis on Berberis vulgaris

An isolate of the basidiomycete Puccinia striiformis, which causes yellow (stripe) rust on wheat, was selfed on the newly discovered alternate host, Berberis vulgaris. This allowed a study of the segregation of molecular markers and virulence in the progeny isolates, and of the development of fungal sexual structures and spore forms.

New article: Origin, Migration Routes and Worldwide Population Genetic Structure of the Wheat Yellow Rust Pathogen Puccinia striiformis f.sp. tritici

This collaborative work between Denmark, France and Pakistan describe the worldwide population structure of wheat yellow rust and identifies the centre of diversity of the pathogen in Himalayan and near Himalayan regions.

Race analysis of Puccinia striiformis at GRRC

Please find reports of the non-European Puccinia striiformis race analyses activities at GRRC 2010 - 2013:

Sampling site focus in 2014 will be selected by staff at ICARDA, CIMMYT and NARCs in Africa and Asia, with a focus on high risk epidemic areas. Since 2011, GRRC also accepted samples of stem rust (Puccinia graminis tritici) as agreed upon with the Borlaug Global Rust Initiative and the phase II of the Durable Rust Resistance in Wheat Project (DRRW). GRRC can only process samples according to available space and resources at any time, and we cannot guarantee to process all samples received. This report deals only with yellow rust. Submission procedures are enclosed at the end of the report, 2012.

RUSTFIGHT - Meeting the new challenges from infectious rust fungi on crop plants

The Danish Research Council for Strategic Research is contributing 19.8m DKK to a new research project to be led by Aarhus University. The results from the project will bring more knowledge to the prevention and control of wheat rust.

The research will be a collaboration between The Global Rust Reference Centre at Aarhus University, University of Copenhagen, Technical University of Denmark, Sejet Planteforædling and leading international institutions.

In the project the scientists will try to decode how and why the fungus starts to develop so aggressively. They will also prepare a list of the genetic codes of the fungus – the so-called effectors – that are responsible for the ability of the fungus to adapt to new wheat varieties. These effectors will be screened and used to develop wheat cultivars with durable rust resistance.

Another ambition is to track down rust resistance in resistant wheat varieties and strains made available from international institutions to Danish plant breeders.

Collaboration with Icarda and Cimmyt

The centre was established in 2008 as a global hub for investigating wheat rust upon the request of the international institutions International Maize and Wheat Improvement Center (CIMMYT), based in Mexico, and International Center for Agricultural Research in the Dry Areas (ICARDA), which is based in Syria. With the new grant the activities at the reference centre will expand markedly.

The Borlaug Global Rust Initiative

The Borlaug Global Rust Initiative (BGRI), founded by the late Dr. N.E. Borlaug, has the overarching objective of systematically reducing the world’s vulnerability to stem, yellow, and leaf rusts of wheat and facilitatingg the evolution of a sustainable international system to contain the threat of wheat rusts and continue the enhancements in productivity required to withstand future global threats to wheat.
