Effect of root exudate (RE) on N₂O reduction by Pseudomonas sp. TF716. (a) Time profile of the N₂O concentration in the medium with or without the RE. (b) Comparison of the relative N₂O reduction rates (w/o RE: without RE; RE_TF: RE of tall fescue; RE_M: RE of maize). Different letters indicate a significant difference in each plot (p < 0.05).
