Soil metatranscriptome demonstrates a shift in C, N, and S metabolisms of a grassland ecosystem in response to elevated atmospheric CO₂.

ABSTRACT: Soil organisms play an important role in the equilibrium and cycling of nutrients. Because elevated CO₂ (eCO₂) affects plant metabolism, including rhizodeposition, it directly impacts the soil microbiome and microbial processes. Therefore, eCO₂ directly influences the cycling of different elements in terrestrial ecosystems. Hence, possible changes in the cycles of carbon (C), nitrogen (N), and sulfur (S) were analyzed, alongside the assessment of changes in the composition and structure of the soil microbiome through a functional metatranscriptomics approach (cDNA from mRNA) from soil samples taken at the Giessen free-air CO₂ enrichment (Gi-FACE) experiment. Results showed changes in the expression of C cycle genes under eCO₂ with an i
