野火会对外生菌根（EM）真菌群落产生负面影响。然而，在欧亚大陆东部森林中，由于野火造成的社区结构的潜在变化很少得到评估，那里的地表火灾频繁。我们调查了EM真菌群落在aLarixgmelinii为主的森林，在2003年烧毁的泽亚，在俄罗斯远东地区。从燃烧和邻近未燃烧的森林地点共收集了120个土壤样本。对EM真菌根尖进行形态分型，并获得用于真菌鉴定的内部转录间隔区（ITS）序列。我们检测到147个EM真菌操作分类单位，EM真菌丰富度在烧伤现场比未烧伤现场低25%。EM真菌组成的特点是发生的干扰适应真菌（双壳菌属和Wilcoxina）在烧伤部位和后期演替真菌（乳菇属，RussulaandCortinarius）在未烧伤的网站。这些结果表明，火灾后16年，EM真菌群落没有恢复到火灾前的水平，Suillusspecies是该地区EM真菌的优势种。gmelinii，具有更大的丰富度和频率在燃烧的网站。落叶松和Suillus都表现出适应性特征，以迅速殖民火灾干扰的栖息地。欧亚大陆东部常见的频繁的地表火灾可能在落叶松林中发挥重要作用，伴随着与它们密切相关的EM真菌。
Wildfires can negatively affect ectomycorrhizal (EM) fungal communities. However, potential shifts in community structures due to wildfires have rarely been evaluated in the forests of eastern Eurasia, where surface fires are frequent. We investigated EM fungal communities in aLarix gmelinii-dominated forest that burned in 2003 in Zeya, in the Russian Far East. A total of 120 soil samples were collected from burned and adjacent unburned forest sites. The EM fungal root tips were morphotyped and internal transcribed spacer (ITS) sequences were obtained for fungal identification. We detected 147 EM fungal operational taxonomic units, and EM fungal richness was 25% lower at the burned site than at the unburned site. EM fungal composition was characterized by the occurrence of disturbance-adapted fungi (AmphinemaandWilcoxina) at the burned site and late-successional fungi (Lactarius,RussulaandCortinarius) at the unburned site. These findings suggest that the EM fungal communities did not recover to pre-fire levels 16 years after the fire.Suillusspecies were the dominant EM fungi onL. gmelinii, with greater richness and frequency at the burned site. BothLarixandSuillusexhibit adaptive traits to quickly colonize fire-disturbed habitats. Frequent surface fires common to eastern Eurasia are likely to play important roles in maintainingLarixforests, concomitantly with their closely associated EM fungi.
