Abstract

Plants may benefit from more diverse communities of arbuscular mycorrhizal fungi (AMF), as functional complementarity of AMF may allow for increased resource acquisition, and because a high AMF diversity increases the probability of plants matching with an optimal AMF symbiont.
We repeatedly radiolabeled plants and AMF in the glasshouse over c. 9 months to test how AMF species richness (SR) influences the exchange of plant C (¹⁴C) for AMF P (³²P & ³³P) and resulting shoot nutrients and mass from a biodiversity–ecosystem functioning perspective.
Plant P acquisition via AMF increased with sown AMF SR, as did shoot biomass, shoot P, and shoot N. The rate of plant C transferred to AMF for this P (C:P) decreased with sown AMF SR.
Plants in plant communities benefit from inoculation with a variety of AMF species via more favorable resource exchange. Surprisingly, this effect did not differ among functionally distinct communities comprised entirely of either legumes, nonlegume forbs, or C3 grasses.

AMF多样性促进植物群落磷的吸收，降低单位磷的碳成本

植物可能受益于更多样化的丛枝菌根真菌（AMF）群落，因为AMF的功能互补性可能允许增加资源获取，而且因为高AMF多样性增加了植物与最佳AMF共生体匹配的可能性。在9个月的时间里，我们在温室中反复对植物和AMF进行放射性标记，以测试AMF物种丰富度（SR）如何影响植物c （14C）与AMF P (32P &；33P)，从生物多样性-生态系统功能的角度来看，由此产生的植被营养和质量。通过AMF获取的植物磷随着播种AMF SR的增加而增加，地上部生物量、地上部磷和地上部氮也随之增加，植物C向AMF转移的P （C:P）比率随着播种AMF SR的降低而降低。植物群落中的植物通过更有利的资源交换从接种多种AMF物种中获益。令人惊讶的是，这种效应在完全由豆科植物、非豆科植物或C3草组成的功能不同的群落中没有差异。

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.
