非本地树种已被广泛种植或已成为大多数森林景观的归化。目前尚不清楚，如果本地树种的外生菌根真菌（EMF）的多样性和社区从非本地树种的集体不同。或者，EMF物种群落的相似性可能更多地由宿主植物的遗传决定，而不是由植物是本地的还是非本地的。我们研究了这些未知的比较两个属，本地和非本地的栎robur和红栎和本地和非本地的樟子松和黑松在一个35岁的共同花园在波兰。利用分子和形态学的方法，我们确定EMF物种从外生菌根根尖和孢子果收集在单一栽培树地块。结果表明，共鉴定出69种EMF，其中38种为孢子果，18种为外生菌根，13种为孢子果和外生菌根均为外生菌根。观察到的EMF物种都是本地的，通常与泛北极分布范围有关。我们发现，土著Q。鲁伯有一个。120%的总EMF物种丰富度比非本地Q。rubra，而天然樟子松具有ca.总EMF物种丰富度比非本地黑猩猩低25%。因此，跨属，有没有证据表明，本地物种有较高的EMF物种多样性比外来物种。此外，我们发现，更高的相似性，EMF群落之间的两种松之间比两种栎。这些结果支持归化的非本地树木的互惠协会与世界性的和新的真菌。
Non-native tree species have been widely planted or have become naturalized in most forested landscapes. It is not clear if native trees species collectively differ in ectomycorrhizal fungal (EMF) diversity and communities from that of non-native tree species. Alternatively, EMF species community similarity may be more determined by host plant phylogeny than by whether the plant is native or non-native. We examined these unknowns by comparing two genera, native and non-native Quercus robur and Quercus rubra and native and non-native Pinus sylvestris and Pinus nigra in a 35-year-old common garden in Poland. Using molecular and morphological approaches, we identified EMF species from ectomycorrhizal root tips and sporocarps collected in the monoculture tree plots. A total of 69 EMF species were found, with 38 species collected only as sporocarps, 18 only as ectomycorrhizas, and 13 both as ectomycorrhizas and sporocarps. The EMF species observed were all native and commonly associated with a Holarctic range in distribution. We found that native Q. robur had ca. 120% higher total EMF species richness than the non-native Q. rubra, while native P. sylvestris had ca. 25% lower total EMF species richness than non-native P. nigra. Thus, across genera, there was no evidence that native species have higher EMF species diversity than exotic species. In addition, we found a higher similarity in EMF communities between the two Pinus species than between the two Quercus species. These results support the naturalization of non-native trees by means of mutualistic associations with cosmopolitan and novel fungi.
