Fig. 1: Indica and japonica subspecies show varied biomass accumulation and nitrogen-use divergence.
From: MYB61 is regulated by GRF4 and promotes nitrogen utilization and biomass production in rice

a–c Boxplots of the mean amount of dry biomass, leaf area, and total N content of indica (Ind) and japonica (Jap) accessions growing under different nitrogen supply at the tillering stage. d Boxplot of the mean increment of biomass for each unit of added nitrogen fertilizer of indica (Ind) and japonica (Jap) accessions growing under different nitrogen supply at the tillering stage. The mean values in (a–d) were obtained from nine individual plants of each accession. Box bounds represent the 25th and 75th percentile, center line represents the median, × indicates the mean, and whiskers represent the 25th percentile − 1.5 * the interquartile range and the 75th percentile + 1.5 * the interquartile range. Statistical significance was calculated with two-tailed Welch’s unpaired t-test and p values are indicated. e, f Correlation analysis of leaf area with dry biomass (e) and with N content (f) based on the data shown in (a–c). N0, N1, and N2 in this figure indicate 0, 96, and 192 (kg/ha) of N, separately. Source data are provided as a Source Data file.
