Tree species identity is associated with rhizosphere microbiome assembly via root metabolite-mediated feedbacks in subtropical forests

ABSTRACT: This experiment investigates the rhizosphere metabolome of two subtropical tree species (Pinus massoniana and Liquidambar formosana) grown in pure and mixed forest stands. Rhizosphere soil samples were collected from each forest type, and root-associated metabolites were extracted and analyzed using untargeted liquid chromatography–mass spectrometry (LC-MS) in both positive and negative ionization modes. The primary objective is to characterize the metabolic profiles associated with different tree species and neighbor interactions, and to provide a comprehensive metabolite dataset that can be linked to microbial community composition and soil nutrient dynamics. The dataset includes raw LC-MS files, feature tables, and annotated putative metabolite identifications.
