三江平原的泥炭地可能更容易受到全球变暖的影响，因为它们位于北部泥炭地的最南端边界。与细菌不同，真菌经常被忽视，尽管它们在泥炭地生态系统的物质循环中发挥着重要作用。因此，我们必须加深对泥炭地真菌群落结构和多样性的了解。本研究利用高通量Illumina测序技术对位于北部泥炭地南缘的三江平原三个沼泽地的真菌群落进行了研究。泥炭土是从不同时期发育的三个沼泽中采集的。共获得463,198条真菌ITS序列，这些序列至少分为6个门、21个纲、60多个目、200多个属。三个地点的真菌群落结构不同，以子囊菌门和担子菌门为主。然而，这三个分部之间的任何 α 多样性指数均无显着差异（p > 0.05）。研究发现，土壤年龄和碳（C）积累率以及总碳（TC）、总氮（TN）、C/N比和容重与几种优势真菌类群的丰度密切相关。我们捕获了丰富的真菌群落，并确认了主要的类群是在其他北部泥炭地中经常发现的类群。研究发现，土壤年龄和碳积累率在塑造真菌群落结构方面发挥着重要作用。
Peatlands in the Sanjiang Plain could be more vulnerable to global warming because they are located at the southernmost boundary of northern peatlands. Unlike bacteria, fungi are often overlooked, even though they play important roles in substance circulation in the peatland ecosystems. Accordingly, it is imperative that we deepen our understanding of fungal community structure and diversity in the peatlands. In this study, high-throughput Illumina sequencing was used to study the fungal communities in three fens in the Sanjiang Plain, located at the southern edge of northern peatlands. Peat soil was collected from the three fens which developed during different periods. A total of 463,198 fungal ITS sequences were obtained, and these sequences were classified into at least six phyla, 21 classes, more than 60 orders and over 200 genera. The fungal community structures were distinct in the three sites and were dominated by Ascomycota and Basidiomycota. However, there were no significant differences between these three fens in any α-diversity index (p > 0.05). Soil age and the carbon (C) accumulation rate, as well as total carbon (TC), total nitrogen (TN), C/N ratio, and bulk density were found to be closely related to the abundance of several dominant fungal taxa. We captured a rich fungal community and confirmed that the dominant taxa were those which were frequently detected in other northern peatlands. Soil age and the C accumulation rate were found to play important roles in shaping the fungal community structure.
