- First Report of Ug99 Wheat Stem Rust Caused by Puccinia graminis f. sp. tritici in South Asia(American Phytopathological Society, 2024) Patpour, M.; Baidya, S.; Basnet, R.; Justesen, A.F.; Hodson, D.P.; Thapa, D.B.; Hovmoller, M.S.
Publication - 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) Patpour, M.; Hovmoller, M.S.; Hodson, D.P.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 Middle East, and Europe. Here, we report the presence of additional virulence to Sr25 in the TKTTF population, a resistance gene transferred to several Australian and CIMMYT wheat genotypes.
Publication - Potential for re-emergence of wheat stem rust in the United Kingdom(Nature Research, 2018) Lewis, C. M.; Persoons, A.; Bebber, D.; Kigathi, R.; Maintz, J.; Findlay, K.; Bueno Sancho, V.; Corredor-Moreno, P.; Harrington, S.A.; Ngonidzashe Kangara; Berlin, A.; Garcia, R.; German, S.E.; Hanzalova, A.; Hodson, D.P.; Hovmoller, M.S.; Huerta-Espino, J.; Imtiaz, M.; Mirza, J.I.; Justesen, A.F.; Niks, R.; Ali Omrani; Patpour, M.; Pretorius, Z.; Ramin Roohparvar; Sela, H.; Singh, R.P.; Steffenson, B.; Visser, B.; Fenwick, P.; Thomas, J.; Wulff, B.B.H.; Saunders, D.G.O.Wheat stem rust, a devastating disease of wheat and barley caused by the fungal pathogen Puccinia graminis f. sp. tritici, was largely eradicated in Western Europe during the mid-to-late twentieth century. However, isolated outbreaks have occurred in recent years. Here we investigate whether a lack of resistance in modern European varieties, increased presence of its alternate host barberry and changes in climatic conditions could be facilitating its resurgence. We report the first wheat stem rust occurrence in the United Kingdom in nearly 60 years, with only 20% of UK wheat varieties resistant to this strain. Climate changes over the past 25 years also suggest increasingly conducive conditions for infection. Furthermore, we document the first occurrence in decades of P. graminis on barberry in the UK . Our data illustrate that wheat stem rust does occur in the UK and, when climatic conditions are conducive, could severely harm wheat and barley production.
