The ability of wild blueberries to adapt to their harsh environment is believed to be closely related to their symbiosis with ericoid mycorrhizal fungi, which produce enzymes capable of organic matter mineralization. Although some of these fungi have been identified and characterized, we still know little about the microbial ecology of wild blueberry. Our study aims to characterize the fungal and bacterial rhizosphere communities of Vaccinium angustifolium (the main species encountered in wild blueberry fields). Our results clearly show that the fungal order Helotiales was the most abundant taxon associated with V. angustifolium. Helotiales contains most of the known ericoid mycorrhizal fungi which are expected to dominate in such a biotope. Furthermore, we found the dominant bacterial order was the nitrogen‐fixing Rhizobiales. The Bradyrhizobium genus, whose members are known to form nodules with legumes, was among the 10 most abundant genera in the bacterial communities. In addition, Bradyrhizobium and Roseiarcus sequences significantly correlated with higher leaf‐nitrogen content. Overall, our data documented fungal and bacterial community structure differences in three wild blueberry production fields.

进入野生蓝莓（Vaccinium angustifolium）的根际微生物群。

野生蓝莓适应其恶劣环境的能力被认为与它们与类胡萝卜素菌根真菌的共生密切相关，后者产生能够使有机物矿化的酶。尽管已鉴定并鉴定了其中一些真菌，但我们对野生蓝莓的微生物生态学仍然知之甚少。我们的研究旨在表征越桔（野蓝莓田中遇到的主要物种）的真菌和细菌根际群落。我们的结果清楚地表明，真菌顺序Helotiales是与V. angustifolium相关的最丰富的分类单元。Helotiales包含大多数已知的类胡萝卜素菌根真菌，这些真菌有望在这种生物群落中占主导地位。此外，我们发现主要的细菌顺序是固氮根瘤菌。该根瘤菌属，其成员是众所周知的形式结节豆类，在细菌群落的10种最丰富的属间。此外，缓生根瘤菌和玫瑰气菌序列与较高的叶氮含量显着相关。总体而言，我们的数据记录了三个野生蓝莓生产领域中真菌和细菌群落结构的差异。
