摘要

植物多样性对生态系统功能的积极影响往往归因于不同植物群落中共生菌的积累和拮抗菌的稀释。虽然植物多样性的增加改变了与资源获取相关的性状，但尚不清楚它是否会减少防御分配，这种减少在根和叶之间是否不同，或在物种之间是否不同。为了回答这些问题，我们在一个19年的生物多样性实验中，评估了植物物种丰富度、植物物种身份及其相互作用对16种植物23个理化叶片和细根防御性状表达的影响。只有单位面积叶质量、叶片和根系干物质含量、根系氮以及与资源获取和防御相关的性状对物种丰富度有一致的响应。然而，物种丰富度促进了这些防御在叶片和细根中的解耦，可能是对不同群落资源限制的响应。物种特异性反应是罕见的，与化学防御和互惠互利合作有关，可能是对物种特异性拮抗剂的稀释和互惠互利积累的反应。总之，我们的研究表明，不同群落的资源限制可能介导了植物防御性状与拮抗剂稀释的关系。

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.
