Fig. 2: Comparison of the TPM of functional genes involved in all nitrogen metabolism pathways in the rhizomicrobiomes of wild and domesticated rice based on the KEGG functional profiles.

Asterisks indicate significant differences between the two groups (two-sided Welch’s t-test, narG p = 4.89E-08, narH p = 4.75E-08, narI p = 0.429, napA p = 0.0001, napB p = 0.001, narB p = 0.056, NR p = 0.398, nasA p = 1.75E-06, nasB p = 0.629, nirB p = 0.265, nirD p = 6.21E-06, nrfH p = 0.003, nrfA p = 0.325, NIT-6 p = 0.285, nirA p = 0.0004, amoA p = 0201, amoB p = 0.126, amoC p = 0.349, hao p = 0.122, nirK p = 2.88E-09, nirS p = 0.003, norB p = 0.082, norC p = 0.568, nosZ p = 2.90E-06, nifD p = 7.00E-12, nifH p = 3.37E-13, nifK p = 2.28E-17), group wild rice (n = 24) and group domesticated rice (n = 35), data were presented as mean values ± SD; TPM (transcripts per million); Blue arrows indicate that the TPM of genes involved in the pathway is higher in the domesticated rice rhizosphere, and red arrows indicate that the TPM of genes involved in that pathway is higher in the wild rice rhizosphere.
