摘要

许多植物物种经历了一个漫长的地下阶段，在此期间它们完全依赖菌根真菌提供碳。虽然这种真菌异养策略涵盖了苔类、石松类和蕨类植物，但大多数实证研究都集中在被子植物上。本研究探讨了一种具有真菌异养配子体的早期分化蕨类植物权杖属（蛇舌科）的真菌关联。我们分析了权杖属配子体的萌发模式和真菌关联，并将其与光合孢子体的分布和菌根伴侣进行了比较。高通量测序数据显示，真菌异养配子体始终与Entrophospora目真菌（Glomeromycotina）结合，而光合孢子体主要与来自肾小球科（Glomerales, Glomeromycotina）的真菌结合。因此，配子体表现为空间集群，而不与成体植物联系。这是第一个关于芽孢科（和芽孢目）和真菌异养植物之间联系的文献。权杖菌根群落在生命阶段的剧烈变化可能反映了发育过程中生理需求的变化。进一步的研究是必要的，以确定与Entrophosporaceae的关联是否广泛存在于分枝异养物种中，并阐明这些菌根转移的功能和生理机制。

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.
