Relationships between rhizosphere microbial communities, soil abiotic properties and root trait variation within a pine species

Rhizosphere microbes play important roles in plant performance and ecosystem functioning. It is becoming increasingly clear that rhizosphere communities vary with soil properties and variation in root traits among plant species. However, less is known about whether and how variation in root traits within plant species influences the rhizosphere microbial communities.
We evaluated the intraspecific root traits variation and explored their associations with bacterial and fungal communities in rhizosphere by focusing on an ectomycorrhizal tree species, i.e., Pinus massoniana, in 22 sites in subtropical China.
The first dimension of the principal component analysis on root traits revealed evidence for the ‘conservation’ gradient of the root economics space. Overall, root traits explained more variation in fungal communities than in bacterial communities in the rhizosphere. Functional composition of rhizosphere microbial communities changed significantly along the ‘conservation’ gradient, wi..., , , The data set was obtained from a field observation study in Pinus massoniana forests in subtropical China. The data set includes root traits data, soil properties data, and bacterial and fungal community composition data from the rhizosphere based on high-throughput sequencing.

根际微生物在植物生长表现与生态系统功能中发挥关键作用。现有研究愈发清晰地表明，根际群落随土壤性质以及不同植物物种间根系性状的差异而发生改变。然而，目前学界对植物种内根系性状变异是否以及如何影响根际微生物群落的认知仍较为有限。

本研究以中国亚热带地区22个样地的外生菌根树种马尾松（*Pinus massoniana*）为研究对象，评估了种内根系性状变异，并探讨其与根际细菌、真菌群落的关联关系。

对根系性状开展的主成分分析第一维度，揭示了根系经济空间的‘保守型’梯度特征。总体而言，根际真菌群落的变异较细菌群落更多地可由根系性状所解释。根际微生物群落的功能组成沿‘保守型’梯度发生了显著变化，[原文内容截断]。本数据集来源于中国亚热带地区马尾松林的野外观测研究，包含根系性状数据、土壤性质数据，以及基于高通量测序获得的根际细菌与真菌群落组成数据。
