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
(Frontiers, 2017)
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 ...

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 ...

Emergence of virulence to SrTmp in the Ug99 race group of wheat stem rust, Puccinia graminis f. sp. tritici, in Africa
(American Phytopathological Society (APS), 2016)
The Ug99 race (TTKSK) of wheat stem rust was first detected in Uganda in 1998 (Pretorius et al. 2000) and since then seven additional variants have been reported, i.e., TTKSF, TTKST, TTTSK, TTKSP, PTKSK, PTKST, and TTKSF+ ...

First Report of the Ug99 race group of Wheat Stem Rust, Puccinia graminis f. sp. tritici, in Egypt in 2014
(American Phytopathological Society (APS), 2016)
Since the first detection of race TTKSK (Ug99) of Puccinia graminis f. sp. tritici in Uganda in 1998 (Pretorius et al. 2000), it has been a priority to track its further spread to other wheat growing areas. To date, 10 ...
