An accurate understanding of the diversity and distribution of fungal symbioses in land plants is essential for mycorrhizal research. Here we update the seminal work of Wang and Qiu (Mycorrhiza 16:299-363, 2006) with a long-overdue focus on early-diverging land plant lineages, which were considerably under-represented in their survey, by examining the published literature to compile data on the status of fungal symbioses in liverworts, hornworts and lycophytes. Our survey combines data from 84 publications, including recent, post-2006, reports of Mucoromycotina associations in these lineages, to produce a list of at least 591 species with known fungal symbiosis status, 180 of which were included in Wang and Qiu (Mycorrhiza 16:299-363, 2006). Using this up-to-date compilation, we estimate that fewer than 30% of liverwort species engage in symbiosis with fungi belonging to all three mycorrhizal phyla, Mucoromycota, Basidiomycota and Ascomycota, with the last being the most widespread (17%). Fungal symbioses in hornworts (78%) and lycophytes (up to 100%) appear to be more common but involve only members of the two Mucoromycota subphyla Mucoromycotina and Glomeromycotina, with Glomeromycotina prevailing in both plant groups. Our fungal symbiosis occurrence estimates are considerably more conservative than those published previously, but they too may represent overestimates due to currently unavoidable assumptions.

古代陆地植物谱系中真菌共生体的分布和演化


准确了解陆地植物中真菌共生体的多样性和分布对于菌根研究至关重要。在此，我们更新了 Wang 和 Qiu 的开创性工作（Mycorriza 16:299-363, 2006），通过检查已发表的文献汇编有关地钱、金鱼藻和石松植物中真菌共生状况的数据。我们的调查结合了 84 份出版物的数据，包括 2006 年后最近关于这些谱系中毛霉菌亚门关联的报告，产生了至少 591 种已知真菌共生状态的物种清单，其中 180 种包含在 Wang 和 Qiu 中（菌根 16） ：299-363，2006）。根据这份最新的汇编，我们估计只有不到 30% 的地钱物种与属于所有三个菌根门（毛霉菌门、担子菌门和子囊菌门）的真菌共生，其中后者分布最广（17%）。金鱼藻 (78%) 和石松植物 (高达 100%) 中的真菌共生似乎更为常见，但仅涉及毛霉菌亚门毛霉菌亚门和肾小球菌亚门的成员，其中肾小球菌亚门在这两个植物类群中占主导地位。我们对真菌共生发生的估计比之前发表的估计要保守得多，但由于目前不可避免的假设，它们也可能代表了高估。
