Manipulation of soil mycorrhizal fungi Influences floral display traits

Most plants form root hyphal relationships with mycorrhizal fungi, especially arbuscular mycorrhizal fungi (AMF). These associations are known to positively impact plant biomass and competitive ability. However, less is known about how mycorrhizae may impact other ecological interactions, such as those mediated by pollinators.
We performed a meta-regression of studies that manipulated AMF and measured traits related to pollination, including floral display, rewards, visitation, and reproduction, extracting 63 studies with 423 effects.
On average, the presence of mycorrhizae was associated with positive effects on floral traits. Specifically, we found impacts of AMF on floral display, pollinator visitation and reproduction, and a positive but non-significant impact on rewards. Studies manipulating mycorrhizae with fungicide tended to report contrasting results, possibly because fungicide destroys both beneficial and pathogenic microbes.
Our study highlights the potential for relationship..., Literature search, as described in the manuscript's main text's methods section., , ARTICLE INFORMATION

绝大多数植物会与菌根真菌（mycorrhizal fungi），尤其是丛枝菌根真菌（arbuscular mycorrhizal fungi, AMF）形成根内菌丝共生关系。已有研究证实，这类共生关系可正向提升植物生物量与竞争能力。然而，学界对菌根如何影响其他生态互作——例如由传粉者介导的互作——的认知仍较为有限。

我们针对操纵丛枝菌根真菌并测定传粉相关性状的研究开展了元回归（meta-regression）分析，最终纳入包含423个效应量（effect sizes）的63项研究，所测定的性状涵盖花部展示、花部报酬、传粉者访花行为与繁殖表现。

平均而言，菌根的存在与花部性状的正向变化显著相关。具体而言，我们发现丛枝菌根真菌对花部展示、传粉者访花行为及植物繁殖均存在显著影响，而对花部报酬仅呈现正向但未达统计学显著性的效应。使用杀菌剂（fungicide）操纵菌根群落的研究往往得到相悖的结果，这可能是由于杀菌剂会同时杀灭有益与致病微生物。

本研究凸显了植物-菌根共生关系对花部相关性状的潜在调控作用……详见论文正文方法部分所述的文献检索流程。
