Halophytes have high species diversity and play important roles in ecosystems. However, endophytic fungi of halophytes in desert ecosystems have been less investigated. In this study, we examined endophytic fungi associated with the stem and root of ten halophytic species colonizing the Gurbantonggut desert. A total of 36 endophytic fungal taxa were obtained, dominated by , , and Pezizomycotina sp.1. The colonization rate and species richness of endophytic fungi varied in the ten plant species, with higher rates in roots than in stems. The endophytic fungal community composition was significantly affected by plant identity and tissue type. Some endophytic fungi showed significant host and tissue preferences. This finding suggests that host identity and tissue type structure endophytic fungal community in a desert ecosystem.
盐生植物具有较高的物种多样性,并在生态系统中发挥着重要作用。然而,沙漠生态系统中盐生植物的内生真菌研究较少。在本研究中,我们调查了古尔班通古特沙漠中十种盐生植物的茎和根相关的内生真菌。共获得36个内生真菌分类单元,主要为、和盘菌亚门菌物1。十种植物中内生真菌的定殖率和物种丰富度各不相同,根部的定殖率高于茎部。内生真菌群落组成受植物种类和组织类型的显著影响。一些内生真菌表现出明显的宿主和组织偏好。这一发现表明,宿主种类和组织类型构成了沙漠生态系统中的内生真菌群落。
