Abstract

In arbuscular mycorrhizal (AM) fungi, only c. 370 species have been formally described despite these fungal organisms having coevolved with plants for hundreds of millions of years. In contrast to this, dozens of thousands of species are known for many fungal lineages with shorter evolutionary timescales. This Viewpoint highlights some plausible reasons for these striking discrepancies in species description. These include paralogs of ribosomal genes leading to the misidentification of AM fungal species in phylogenetic analyses and polymorphism in homologous morphological traits. We propose to address issues surrounding AM fungal taxonomy using genome-based approaches that will allow the determination of whether individual AM fungal isolates really belong to the same species.

在丛枝菌根（AM）真菌中，只有约 370 个物种被正式描述，尽管这些真菌生物与植物共同进化了数亿年。与此形成鲜明对比的是，许多进化时间尺度较短的真菌品系却有成千上万个物种。本 "视点 "强调了物种描述中出现这些显著差异的一些合理原因。这些原因包括核糖体基因的同源物导致系统进化分析中对AM真菌物种的错误识别，以及同源物形态特征的多态性。我们建议使用基于基因组的方法来解决围绕上午真菌分类的问题，从而确定各个上午真菌分离物是否真正属于同一物种。

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.
