放线菌以其产生多种次生代谢物（例如抗生素）的代谢潜力而闻名。放线菌在生物地球化学循环和土壤发育中也发挥着重要作用。然而，关于植被类型对干旱地区土壤放线菌群落结构的影响知之甚少。为此，我们对黑河流域五类生态系统（乔木林、灌木、草甸、荒漠、农田）的放线菌群落进行了分析。利用16S rRNA高通量测序，我们发现了11类放线菌，其中优势类为放线菌（36.2%）、嗜热嗜热菌（28.3%）、酸微菌（19.4%）。所有样本均包含5纲、15目、20科、36属。主要的多面性属是盖氏菌属、Solirubrobacter 属、诺卡氏菌属、分枝杆菌属和假诺卡氏菌属。放线菌群落结构受环境和植被类型影响显着。荒漠生态系统中放线菌群落多样性较高，该生态系统中未分类序列比例最高，代表稀有放线菌。使用 PICRUSt 进行的功能宏基因组预测表明，放线菌在沙漠和耕地生态系统的氮循环中发挥着重要作用。
Actinobacteria are known for their metabolic potential of producing diverse secondary metabolites such as antibiotics. Actinobacteria also playimportant roles in biogeochemical cycling and how soils develop. However, little is known about the effect of the vegetation type on the actinobacterial community structures in soils from arid regions. For these reasons, we have analyzed the actinobacterial communities of five types of ecosystem (tree grove, shrub, meadow, desert, and farm) in the Heihe river basin. Using 16S rRNA high-throughput sequencing, we found 11 classes of Actinobacteria, with dominant classes of Actinobacteria (36.2%), Thermoleophilia (28.3%), Acidimicrobiia (19.4%). Five classes, 15 orders, 20 families and 36 genera were present in all samples. The dominant generalist genera were Gaiella, Solirubrobacter, Nocardioides, Mycobacterium, and Pseudonocardia. The actinobacterial community structures were significantly affected by the environment and vegetation type. The diversity of the actinobacterial community in the desert ecosystem was high, and this ecosystem harbored the highest proportion of unclassified sequences, representing rare Actinobacteria. Functional metagenomic prediction, using PICRUSt, indicated that Actinobacteria play an important role in nitrogen cycling in both desert and cultivated farm ecosystems.
