Fig. 4

Heatmap showing the enrichment of functional genes involved in (a) carbon degradation, (b) nitrogen cycling, (c) sulfur cycling, and (d) other elements such as iron, arsenic, and selenium metabolic pathways among three soil layers. The significance of the changes in gene abundance are evaluated by generalized linear model with a negative binomial distribution using edgeR100 package. P values were obtained from two-sided Likelihood Ratio Tests (LRTs) and adjusted for multiple comparisons using the Benjamini-Hochberg false discovery rate (FDR) procedure. Genes with significant changes in abundance (P < 0.05) are marked with an asterisk (*). LogFC: log2-fold change. The full names of the genes in this figure are listed in Supplementary Data 2. SUR surface layer, SUB subsurface layer, PL permafrost layer. Source data are provided as a Source Data file.
