中文摘要	采集新疆且末地区沙尘暴空气微生物样品,揭示沙尘暴前期、中期和后期真菌组成和群落结构差异,为沙尘暴灾害预警提供依据.利用可培养方法和高通量测序技术,分析新疆且末地区沙尘暴空气真菌的组成和物种多样性.结果表明:(1)可培养空气真菌隶属于子囊菌门,其优势菌属为链格孢属(Alternaria,55.56%);(2)高通量测序技术检测的沙尘暴空气样品中共获得555 548条有效序列,Sobs指数在10-100之间,Shannon指数在1.106-2.903之间,Coverage值在0.999-1之间,表明测序数据信息量充足.序列聚类为257个可操作分类单元,包括6个门121个属.其中,门水平上,优势菌门为子囊菌门(Ascomycota,58.66%)和担子菌门(Basidiomycota,31.03%).优势菌属为链格孢属(Alternaria,21.86%)、栓菌属(Trametes,20.82%)、耐温酵母(Geuhomyces,20.30%);沙尘暴中期空气真菌多样性>沙尘暴前期空气真菌多样性>沙尘暴后期空气真菌多样性;(3)冗余分析结果显示,沙尘暴空气真菌多样性与湿度、气压、经度呈正相关,与海拔、维度、温度呈负相关.本研究表明沙尘暴蕴藏着丰富的微生物资源,不同的环境因子是影响沙尘暴空气微生物群落结构变化的重要因素,结果可为荒漠化治理和开发微生物新资源提供一定理论依据.
英文摘要	Airborne microbial samples of sandstorms in the Qiemo area of Xinjiang were collected to investigate the differences in fungal composition and community structure in the early,middle,and late stages of sandstorms,to provide a basis to determine early warning signals of sandstorms.Using cultivable methods and high-throughput sequencing technology,the composition and species diversity of sand dust air fungi in the Qiemo area of Xinjiang were analyzed.The results showed that(1)the culturable air fungi belonged to the Ascomycete phylum,and the dominant genus was Alternaria(55.56%);(2)a total of 555 548 effective sequences were obtained from the sandstorm air samples by high-throughput sequencing technology.The Sobs index was between 10 and 100,the Shannon index was between 1.106 and 2.903,and the coverage value was between 0.999 and 1.These results indicate that the sequencing data contained sufficient information.Sequence clustering included 257 operable taxa,including six gates and 121 genera.At the phylum level,the dominant phyla were Ascomycota(58.66%)and Basidiomycota(31.03%).The dominant genera were Alternaria(21.86%),Trametes(20.82%),and Guehomyces(20.30%),and the diversity of airborne fungi in the middle stage of sandstorm was higher than that in the early stage of sandstorm as well as in the later stage;(3)Redundancy analysis results showed that humidity,air pressure,and longitude were positively correlated with airborne fungal diversity in sandstorms,and negatively correlated with altitude,latitude,and temperature.In summary,sand and dust storms contain abundant microbial resources.Different environmental factors are important components that affect the composition of the microbial community structure of sand and dust storms.Understanding dust and airborne microorganisms provides a theoretical basis for desertification control and the development of new microbial resources.
