在世界上大多数生态系统中，维管植物和菌根真菌之间的共生关系对碳和养分循环至关重要。大多数维管植物物种都与菌根真菌伴侣有关联，这种关联对双方的碳和营养经济都是必不可少的。然而，尽管其重要性显而易见，关于这种共生关系的数据缺乏：对于大多数维管植物物种，菌根类型是未知的。很少有关于多个生境中菌根感染强度水平的数据。我们翻译并数字化了一个关于前苏联维管植物菌根强度的庞大数据集，以前只能作为Ivan a . Selivanov在1976年用俄语发表的博士论文的硬拷贝附录，国际研究界无法获得。我们将植物分类命名法更新到国际植物名称索引，并根据现代国际文献对菌根和生态术语进行了调整。该数据库包含7445条关于菌根感染类型和强度的记录，来自155科的2970种植物，分布在前苏联的154个地点（主要位于现在的俄罗斯、乌克兰和哈萨克斯坦境内），包括广泛的地质、地形和气候梯度。该数据集包括每个菌种位点组合的感染百分比，包括丛枝型、丛枝型、丛枝型、内生菌根型、暗隔型、兰花型和外生菌根型真菌。每条记录都有详细的地理描述。许多记录描述了土壤和寄主植物群落。大多数遗址都是天然的；10个地点位于植物园内。对1291种植物的菌根感染强度在多个植物群落中进行了量化（2-57）。其余物种在单个地点被描述。Selivanov发展了他自己的量化菌根感染强度的方法。这些方法与目前普遍使用的方法是可比较的，但并不完全相同。基于我们自己在两个遥远的地点（高加索[俄罗斯]和阿比斯库[瑞典]）采集的99种植物样本，我们提供了两种方法之间数据转换的简单公式。该数据库的可用性将有助于解答生物地球化学循环、气候变化影响以及植物和真菌共同进化等重要问题。
The symbiosis between vascular plants and mycorrhizal fungi is paramount for carbon and nutrient cycling in most of the world's ecosystems. Most vascular plant species are associated with mycorrhizal fungal partners, and the association is essential for the carbon and nutrition economies of both partners. However, despite its clear importance, data on this symbiosis are lacking: for most vascular plant species, mycorrhizal type is unknown. Very rarely is there data on the levels of mycorrhizal infection intensity in multiple habitats. We translated and digitized a huge data set on vascular plant mycorrhizal intensity throughout the former Soviet Union, previously available only as a hard copy appendix of the doctoral thesis of Ivan A. Selivanov published in Russian in 1976 and not accessible to the international research community. We updated the taxonomic plant nomenclature to the International Plant Name Index and adjusted mycorrhizal and ecological terminology according to the modern international literature. The database contains 7445 records on mycorrhizal infection type and intensity of 2970 plant species from 155 families, in 154 sites, situated across the former Soviet Union (mostly on the territory of the current Russia, Ukraine, and Kazakhstan), comprising together extensive geological, topographic, and climatic gradients. The data set includes percentage infection for each species-site combination for arbuscular, ericoid, arbutoid, endo-mycorrhizal, dark septate, orchid- and ecto-mycorrhizal fungi. Each record has a detailed description of geography. For many records, soils and host plant community are described. Most of the sites are natural; 10 sites are situated in botanical gardens. For 1291 species the intensity of mycorrhizal infection is quantified in multiple plant communities (2-57). The remaining species are described at single sites. Selivanov developed his own methods for quantifying mycorrhizal infection intensity. These methods are comparable, but not identical to, the methodology commonly used today. Based on our own sampling of 99 plant species collected in two distant sites (Caucasus [Russia] and Abisko [Sweden]), we provide a simple equation for data conversion between the two methods. The availability of this database will help to provide answers to important questions concerning biogeochemical cycling, climate change impacts, and co-evolution of plants and fungi.
