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 ...

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 ...
Article
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+ ...
Article
Emergence and spread of new races of wheat stem rust fungus: continued threat to food security and prospects of genetic control
(American Phytopathological Society (APS), 2015)
Race Ug99 (TTKSK) of Puccinia graminis f. sp. tritici, detected in Uganda in 1998, has been recognized as a serious threat to food security because it possesses combined virulence to a large number of resistance genes found ...

Report
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 ...
Article
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) ...
Article
Phenotypic and genotypic characterization of Race TKTTF of Puccinia graminis f. sp. tritici that caused a Wheat Stem Rust Epidemic in Southern Ethiopia in 2013–14
(American Phytopathological Society (APS), 2015)
A severe stem rust epidemic occurred in southern Ethiopia during November 2013 to January 2014, with yield losses close to 100% on the most widely grown wheat cultivar, ‘Digalu’. Sixty-four stem rust samples collected from ...
Report
Wheat varietal change and adoption of rust resistant wheat varieties in Ethiopia from 2009/10 to 2013/14
(CIMMYT, 2018)
This study tracks wheat varietal adoption by farmers in Ethiopia from 2009/10 to 2013/14 and was based on two nearly identical national wheat variety adoption studies undertaken by EIAR and the International Maize and Wheat ...
