Forest decline is a worldwide phenomenon affecting many species such as Pinus sylvestris. Although it is driven by multiple stressors, the role of tree associated microorganisms remains still unclear. To reduce this knowledge gap we obtained amplicon sequences of the microbiota inhabiting the rhizosphere soil and root endosphere (bacterial 16S rRNA and fungal ITS2) of decline-affected and asymptomatic P. sylvestris trees in spring and summer. The dataset comprised a total of 384 samples from three mountainous areas which yielded an average of 59,592.3 ± 7,371 and 56,894.3 ± 12,983.5 (spring and summer) bacterial and 74,827.9 ± 12,095.4 and 85,363.9 ± 14,199.3 (spring and summer) fungal raw reads, resulting in 23,982.4 ± 11,312.4 (spring) and 17,921.8 ± 10,802.7 (summer) bacterial and 50,571.1 ± 10,499.5 (spring) and 49,509.4 ± 12,673.8 (summer) fungal quality-filtered sequences. These data and the corresponding metadata could be used to identify pine decline bioindicators, to develop novel diagnosis tools of specific microorganisms and could serve as reference against which to compare other microbial communities.
森林衰退是一种影响许多物种（如欧洲赤松）的全球现象。尽管它是由多种压力因素驱动的，但与树木相关的微生物的作用仍不清楚。为了缩小这一知识差距，我们获取了受衰退影响和无症状的欧洲赤松在春季和夏季根际土壤和根内圈（细菌16S rRNA和真菌ITS2）中微生物群的扩增子序列。该数据集总共包含来自三个山区的384个样本，春季和夏季分别产生平均59,592.3 ± 7,371和56,894.3 ± 12,983.5条细菌原始读数，以及74,827.9 ± 12,095.4和85,363.9 ± 14,199.3条真菌原始读数，最终得到春季23,982.4 ± 11,312.4条和夏季17,921.8 ± 10,802.7条细菌以及春季50,571.1 ± 10,499.5条和夏季49,509.4 ± 12,673.8条真菌经过质量过滤的序列。这些数据和相应的元数据可用于识别松树衰退生物指标，开发特定微生物的新型诊断工具，并可作为与其他微生物群落进行比较的参考。
