Abstract: 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 i… Show more

“…7a and Supplementary Fig. 7) showed a very similar overall topology to that reported previously for most of these isolates 27 . The five isolates of the Ug99 lineage, and the thirteen South African and Australian isolates each formed a separate tight clade, consistent with their proposed clonal nature 19-21 .…”

“…for the observed GY reduction (16.31% compared with N 2 ) is the significant increase in LR and SR severity with increasing N supply (Mains, 1917;Huber and Watson, 1974;Ash and Brown, 1991;Lewis et al, 2018). Hence, our results indicated a significant correlation between the rust disease (LR and SR) susceptibility scores and N supply.…”

“…The disease appears after flowering on stems and leaf sheaths, in the form of rust-brown oblong powdering with urediniospore pustules that coalesce in the form of brown stripes and tearing of the epidermis. This disease can reduce winter wheat yields by up to 80% [3]. The Ug99 stem rust emergence in 1999 [4], which overcame the rust resistance of many varieties [5], made it urgent to find sources of resistance and to identify new winter wheat varieties with these genes.…”
