Root traits and soil microorganisms as drivers of plant-soil feedbacks within the sub-arctic tundra meadow

Plant-soil feedback (PSF) can influence the composition of various soil microorganisms (antagonistic and mutualistic), which can have reciprocal effects on plants. At the same time, we do not understand the effects of fine root traits in moderating microbial-driven PSF. We therefore conducted a greenhouse study to aid in understanding the relationship between root traits, soil community composition (PLFAs and high-throughput sequencing data) and plant-soil feedback (PSF). These data therefore include datasets with fine root traits, raw sequence reads from high-throughput sequencing for soil fungi, phospholipid fatty acid data and biomass data after the plant-soil feedback study.

Methods
We conducted a plant-soil feedback study within a greenhouse. Fine root traits and soil microbial community were used in the feedback phase to assess relationship between root traits, soil community composition (PLFAs and high-throughput sequencing data) and plant-soil feedback (PSF).
