Fig. 3: Effects of total and available micronutrients (Fe, Mn, Cu, Zn, Mo, Ni) on soil microbial regulated functions involved in C, N, P, and S cycles.
From: Metallic micronutrients are associated with the structure and function of the soil microbiome
a Number of genes involved in microbial C, N, P, and S cycles whose absolute abundances significantly correlated with soil micronutrients by partial correlation. b Number of genes whose absolute abundances significantly correlated with soil chemical properties by partial correlation. The “mean” represented the average number of genes correlated with all micronutrients or soil macronutrient+pH. c Micronutrient-participated microbial pathways for the C cycling. d Micronutrient-participated microbial pathways for the N cycling. e Micronutrient-participated microbial pathways for the P cycling. f Micronutrient-participated microbial pathways for the S cycling. The labels of micronutrients presented in the pathways were strictly filtered if their correlations with the absolute abundance and relative abundance of corresponding genes were both significant (p < 0.05). Labels with red and blue colors presented that negative and positive correlations between micronutrients and gene abundance. The microorganisms containing the genes in the pathways at the phylum and genus level are presented in Table S4.
