了解土传植物病原体当前和未来的分布对于支持温暖世界中的粮食和纤维生产至关重要。利用全球实地调查和九年实地实验的数据，我们表明，气温升高会增加土传潜在真菌植物病原体的相对丰度。此外，我们提供了这些生物体的全球地图集以及不同气候变化和土地利用情景下的未来分布预测。这些预测显示全球潜在植物病原体的相对丰度总体增加。这项工作增进了我们对潜在真菌植物病原体的全球分布及其对持续气候和土地利用变化的敏感性的了解，这对于减少其发生率和对全球陆地生态系统的影响至关重要。植物病原体威胁粮食安全和生态系统健康。对不同变暖和土地利用情景下潜在真菌植物病原体的预测表明，气候变化下气温升高将导致全球大多数土壤中此类病原体的相对丰度增加。
Understanding the present and future distribution of soil-borne plant pathogens is critical to supporting food and fibre production in a warmer world. Using data from a global field survey and a nine-year field experiment, we show that warmer temperatures increase the relative abundance of soil-borne potential fungal plant pathogens. Moreover, we provide a global atlas of these organisms along with future distribution projections under different climate change and land-use scenarios. These projections show an overall increase in the relative abundance of potential plant pathogens worldwide. This work advances our understanding of the global distribution of potential fungal plant pathogens and their sensitivity to ongoing climate and land-use changes, which is fundamental to reduce their incidence and impacts on terrestrial ecosystems globally.Plant pathogens threaten food security and ecosystem health. Projections of potential fungal plant pathogens under different warming and land-use scenarios indicate that warming temperatures under climate change will lead to increases in the relative abundance of such pathogens in most soils worldwide.
