Fig. 2: Effects of methane (CH4) addition on microbial denitrification of three typical paddy soils.
From: Metabolic coupling between soil aerobic methanotrophs and denitrifiers in rice paddy fields
A Variations in nitrous oxide (N2O) emissions; and B Changes in denitrification gene (nirK and nirS) transcript using RNA reverse transcription. The error bar in (A, B) represents the standard error of triplicate samples, and data are presented as mean values ± standard error. Different lowercase letters in (B) indicate significant differences between the soils with different CH4 concentrations (p < 0.05; n = 3; one-way ANOVA followed by two-sided Tukey post hoc test). Exact p values and Source data are provided as a Source Data file.
