摘要

白粉病是一种重要的经济疾病，由大约1000种不同的真菌引起。牛痘Erysiphe vaccinii是一种新兴的白粉病，正在影响蓝莓产业。牛痘杆菌曾经局限于北美，现在正在中国、摩洛哥、墨西哥和美国等主要蓝莓种植区迅速蔓延，威胁着数百万人的损失。这项研究通过分析植物标本馆标本（一些超过150年）和世界各地收集的新鲜样本，记录了其最近的全球传播。我们的研究结果通过T-BAS整合到“活的系统发育”中，以简化病原体鉴定并能够对新的疫情做出快速反应。我们确定了50个单倍型，在世界范围内的两个主要引入，并揭示了从通才型到专门型病原体的转变。这项研究提供了对宿主专业化复杂性的见解，并强调了解决这一对蓝莓生产的新兴全球威胁的必要性。

An emerging fungal disease is spreading across the globe and affecting the blueberry industry

Powdery mildew is an economically important disease caused by c. 1000 different fungal species. Erysiphe vaccinii is an emerging powdery mildew species that is impacting the blueberry industry. Once confined to North America, E. vaccinii is now spreading rapidly across major blueberry-growing regions, including China, Morocco, Mexico, and the USA, threatening millions in losses.
This study documents its recent global spread by analyzing both herbarium specimens, some over 150-yr-old, and fresh samples collected world-wide.
Our findings were integrated into a ‘living phylogeny’ via T-BAS to simplify pathogen identification and enable rapid responses to new outbreaks. We identified 50 haplotypes, two primary introductions world-wide, and revealed a shift from a generalist to a specialist pathogen.
This research provides insights into the complexities of host specialization and highlights the need to address this emerging global threat to blueberry production.

期刊介绍： New Phytologist is an international electronic journal published 24 times a year. It is owned by the New Phytologist Foundation, a non-profit-making charitable organization dedicated to promoting plant science. The journal publishes excellent, novel, rigorous, and timely research and scholarship in plant science and its applications. The articles cover topics in five sections: Physiology & Development, Environment, Interaction, Evolution, and Transformative Plant Biotechnology. These sections encompass intracellular processes, global environmental change, and encourage cross-disciplinary approaches. The journal recognizes the use of techniques from molecular and cell biology, functional genomics, modeling, and system-based approaches in plant science. Abstracting and Indexing Information for New Phytologist includes Academic Search, AgBiotech News & Information, Agroforestry Abstracts, Biochemistry & Biophysics Citation Index, Botanical Pesticides, CAB Abstracts®, Environment Index, Global Health, and Plant Breeding Abstracts, and others.
