植物病毒群落结构受生境异质性和寄主植物资源利用特征的影响

摘要寄主植物提供了对病毒至关重要的资源，而植物群落的空间结构会影响病毒定殖和疾病发生的龛位。然而，人们对异质植物群落中植物病毒疾病生态学机制的认识仍存在巨大差距。我们结合高通量测序、网络和元群落方法，检验了植物群落组成的生境异质性是否与病毒传播模式和宿主范围的资源利用特征相对应。大多数病毒表现出栖息地特异性，主要通性病毒和潜在宿主储库将群落连接起来。生境异质性与病毒群落结构之间存在关联，病毒群落结构与宿主范围和传播方式等资源利用特征之间也存在关联。病毒物种分布与病毒性状对生境异质性的反应之间的关系取决于尺度，在更细的空间尺度（地点）上比在更大的空间尺度（生境）上更强。研究结果表明，生境异质性对植物病毒群落的形成有一定影响，病毒群落结构与病毒性状反应之间的关系随观察尺度的变化而变化。植物资源分区造成的病毒群落差异可用于跟踪病毒对宿主的性状反应，这对预测疾病的出现非常重要。

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.
