Different roles of nitrogen cycling-related functional genes in soil N turnover and N loss in a subtropical forest under N enrichment and precipitation seasonal distribution change

Nitrogen (N) deposition elevation and precipitation regime alteration have emerged as two dominant factors affecting the environment on global scale. How these two environmental change factors together infulence the soil N dynamics and N losses of tropical and subtropical forests are less known. A field experimental platform containing N addition (N), rainfall seasonality change(R), the interaction of N addition and rainfall seasonality change (NR) and a control (C) were perfomed. Soil N contents, N transformation rates, nitrous oxide (N2O) effluxes, soil nitrifying and denitfirying functional gene abundances, and differentially expressed proteins in the nitrogen metabolism pathway were compared among treatments and between wet-dry seasons.

The dataset includes data of four aspects: (1) soil properties, (2) N transformation rates, (3) abundances of nitrifying and denitrifying functional genes, and (4) differentially expressed proteins.
