Fig. 5: Genes involving biogeochemical cycle associated with environmental variables.

From: Bacterial genome size and gene functional diversity negatively correlate with taxonomic diversity along a pH gradient

Fig. 5

a Heatmap showing correlations between environmental variables and genes involving biogeochemical cycling of carbon, nitrogen, phosphorus, sulfur and iron (n = 36 samples). b Seventeen carbon cycle genes positively correlate with soil pH. c Nitrogen cycle genes are positively or negatively correlated with soil pH. d Eight phosphorus cycle genes positively correlate with soil pH, as compared to that two phosphorus cycle genes negatively correlate with soil pH. The diagrams for sulfur and iron cycles can be found in Supplementary Fig. 18. Source data are provided as a Source Data file.
