Fig. 1

a DNR1 transcript abundance in ZH11 shoots under ambient CO2 (aCO2) and elevated CO2 (eCO2) conditions. Transcript abundance was measured relative to ZH11 under aCO2 (set to 1). Data are mean ± s.e.m. (n = 3 biological replicates). P-value was generated from two-sided Student’s t tests. b DNR1 protein abundance in the shoots of ZH11 and dnr1 under aCO2 and eCO2 conditions. HSP82 serves as a loading control. The red arrow indicates the DNR1 bands. Data are representative of three independent experiments, with similar results. Aboveground biomass (c), N uptake (d), yield (e) and N-use efficiency (f) under aCO2 and eCO2 conditions were measured at maturity. ZH11 and dnr1 indicate japonica variety Zhonghua 11 and its dnr1 mutants, respectively. c–f Data are mean ± s.e.m. (n = 3 biological replicates). P-values were generated from two-way ANOVA. Different letters indicate significant differences among treatments (P < 0.05). Source data are provided as a Source Data file.
