New insights into the spread and evolution of yellow rust at the continental scale

This report presents molecular genotyping and race typing results from the GRRC based on samples of rust infected wheat and triticale collected in 2020 and across four continents, i.e., Europe, Asia, Africa and South America.

This report presents molecular genotyping and race typing results from the GRRC based on samples of rust infected wheat and triticale collected in 2018 and 2019 across four continents, i.e., Europe, Asia, Africa and South America.

This report presents results on Simple Sequence Repeat (SSR) genotyping of samples of Puccinia striiformis from wheat and triticale collected across four continents in 2018, with reference to 2017 results.

In a commentary in Communication Biology, published 4th February 2019, scientists evaluate the risks of re-emergence of wheat stem rust in Europe. In general, the wheat rust “problems” in Europe have been addressed via multiple national initiatives, but in 2018, a new EU H2020 research and innovation program was launched, dealing with all three rust diseases on wheat

In 2017, Argentina faced the worst epidemics of yellow rust since the 1930s. Based on samples collected at 22 epidemic sites in September, the Global Rust Reference Center (GRRC) has identified at least three distinct yellow rust genotypes. Two of these were identical to genotypes first detected in Europe and North Africa in 2015-16.

Unusual and severe epidemics of yellow rust were observed on several continents in 2017. In a number of cases, epidemic sites at different continents were inter-related by prevalence of genetically identical yellow rust genotypes and races.

Up to 2014 wheat stem rust was not considered of major importance in Western Siberia, but severe epidemics in 2015 and 2016 has changed the situation. New research to resolve stem rust epidemiology in the region and additional efforts in breeding for rust resistance is urgently needed.
