本研究旨在探讨沙漠地区寄主植物种类和生活方式以及环境条件对内生真菌组成的影响。利用核糖体核糖体基因新一代测序技术，对中国地区腾格里沙漠铜鼓脑儿、锡林高乐、瓜州3个地点寄生植物锁阳及其寄主唐古特白刺的内生真菌群落进行了研究。通过多元统计分析，评价不同地理位置内生真菌组成的相似性和差异性。这表明，植物遗传是影响内生真菌组成的决定性因素，即使松材线虫和唐古特木霉紧密生长在一起也是如此。不仅如此，真菌组成也受到当地环境和降雨量的很大影响。然而，真菌种类的分布和丰富度表明，地理距离对真菌组成的表征影响不大。总之，植物种类、寄生或非寄生的生活方式以及当地环境对内生真菌种类的数量和多样性有很大的影响，这对于深入了解寄生植物、寄主和内生真菌在沙漠环境下的微生物生态、共生专一性以及三者之间的关系具有重要的意义。
This study was aimed to investigate whether host plant species and lifestyles, and environmental conditions in the desert affect endophytic fungi composition. Endophytic fungal communities from parasitic plant Cynomorium songaricum and its host Nitraria tangutorum were investigated from three sites including Tonggu Naoer, Xilin Gaole, and Guazhou in Tengger and Badain Jaran Deserts in China using the next-generation sequencing of a ribosomal RNA gene region. Similarity and difference in endophytic fungal composition from different geographic locations were evaluated through multivariate statistical analysis. It showed that plant genetics was a deciding factor affecting endophytic fungal composition even when C. songaricum and N. tangutorum grow together tightly. Not only that, the fungal composition was also greatly affected by the local environment and rainfall. However, the distribution and richness of fungal species indicated that the geographical distance exerted little influence on characterizing the fungal composition. Overall, the findings suggested that plant species, parasitic or non-parasitic lifestyles of the plant, and local environment strongly affected the number and diversity of the endophytic fungal species, which may provide valuable insights into the microbe ecology, symbiosis specificity, and the tripartite relationship among parasitic plant, host, and endophytic fungi, especially under desert environment.
