Wheat stem rust, a devastating disease of wheat and barley caused by the fungal pathogen f. sp. , 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 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.
小麦秆锈病是一种由真菌病原体禾柄锈菌小麦专化型引起的对小麦和大麦具有毁灭性的病害，在20世纪中后期在西欧基本被根除。然而，近年来出现了零星的疫情爆发。在这里，我们调查现代欧洲品种缺乏抗性、其替代寄主伏牛花的存在增加以及气候条件的变化是否可能促使其卷土重来。我们报告了英国近60年来首次出现小麦秆锈病，英国只有20%的小麦品种对这种菌株具有抗性。过去25年的气候变化也表明感染条件越来越有利。此外，我们记录了英国数十年来首次在伏牛花上出现禾柄锈菌。我们的数据表明，小麦秆锈病确实在英国发生，并且在气候条件有利时，可能会严重损害小麦和大麦的生产。
