First report of virulence to Sr25 in race TKTTF of Puccinia graminis f. sp. tritici causing stem rust on wheat
(American Phytopathological Society (APS), 2017)
Puccinia graminis f. sp. tritici (Pgt) race TKTTF was reported as the dominant race in the wheat stem rust epidemics in Ethiopia during 2014–15. The race and variants hereof have also been recorded elsewhere in Africa, the ...
Microsatellite analysis and urediniospore dispersal simulations support the movement of Puccinia graminis f. sp. tritici from Southern Africa to Australia
(American Phytopathological Society (APS), 2019)
The Australian wheat stem rust (Puccinia graminis f. sp. tritici) population was shaped by the introduction of four exotic incursions into the country. It was previously hypothesized that at least two of these (races ...
Detection of wheat stem rust races TTHSK and PTKTK in the Ug99 race group in Kenya in 2014
(American Phytopathological Society (APS), 2016)
Wheat stem rust, caused by Puccinia graminis f. sp. tritici, causes severe losses in wheat production under epidemic conditions. The detection of isolate Ug99 in east Africa (Pretorius et al. 2000) has raised global concerns ...
MARPLE, a point-of-care, strain-level disease diagnostics and surveillance tool for complex fungal pathogens
(BioMed Central, 2019)
Background: Effective disease management depends on timely and accurate diagnosis to guide control measures. The capacity to distinguish between individuals in a pathogen population with specific properties such as fungicide ...
Pathogenomic analysis of wheat yellow rust lineages detects seasonal variation and host specificity
(Oxford University Press, 2017)
Recent disease outbreaks caused by (re-)emerging plant pathogens have been associated with expansions in pathogen geographic distribution and increased virulence. For example, in the past two decades’ wheat yellow (stripe) ...
Yellow Rust epidemics worldwide were caused by Pathogen Races from divergent genetic lineages
We investigated whether the recent worldwide epidemics of wheat yellow rust were driven by races of few clonal lineage(s) or populations of divergent races. Race phenotyping of 887 genetically diverse Puccinia striiformis ...
