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

description: 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, with fast-growing copiotrophic bacteria and symbiotic
 ectomycorrhizal fungi were significantly enriched on the ‘acquisition’
 side, while slow-growing oligotrophic bacteria were significantly enriched
 on the ‘conservation’ side of the gradient. Synthesis: Our study
 demonstrates that intraspecific variation in plant roots significantly
 influence rhizosphere microbial communities, which in turn can influence
 plant nutrition and therefore plant performance within the community.
description: 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. GENERAL
