Gene and transcript copies of nirK, nirS, nosZ (clade I and clade II), and the nosZ I/(nirK+nirS) ratio in patches in the absence or presence of AMF. A Pot expt 1. nirK, nirS, and nosZ (clade I and II) gene copies and the nosZ I/(nirK+nirS) ratio in different patches under −AMF and +AMF treatments (n = 8). Control, soil patch; NSfaba and Sfaba, patches with unsterilized (NS) or sterilized (S) faba bean residues, respectively. B Pot expt 2. nirK, nirS, and nosZ (clade I and II) gene copies and the nosZ I/(nirK+nirS) ratio in patches under −AMF and +AMF treatments at both harvests (n = 5). C Pot expt 2. nirK, nirS, and nosZ (clade I and II) transcript copies and the nosZ I/(nirK+nirS) transcript ratio in patches under −AMF and +AMF treatments at both harvests (n = 5). T1 and T2, first (day 24) and second (day 34) harvests, respectively. Asterisks, significant differences between −AMF and +AMF treatments in each patch type (pot expt 1) or at each harvest (pot expt 2) by two-tailed unpaired t test (*, P < 0.05; **, P < 0.01; ***, P < 0.001)
