From: Various microbial taxa couple arsenic transformation to nitrogen and carbon cycling in paddy soils
Potential coupling metabolism of the N and C with As oxidation and reduction. A Spearman correlation of the abundance/activity of the aioA/arxA genes with those of the narG/napA/nirK/nirS/norB/nosZ/nrfA genes. B Spearman correlation of the abundance/activity of arrA/arsC2 genes with pmoA/mcrA genes. Pairwise Spearman’s correlations of these variables are shown with a color gradient, i.e., red-blue for abundance at the DNA level and yellow-green for transcriptional activity at the RNA level. Asterisks (*) represent p values (*, p < 0.05; **, 0.001 < p < 0.01; ***, p < 0.001)
