a
Metabolites that showed significant changes in ZmASR1-OE leaves compared with wild-type leaves (P < 0.05).
b
Metabolites that showed significant decreases in ZmASR1-OE leaves compared with wild-type leaves and/or were correlated to biomass in Arabidopsis (Meyer et al., 2007; Sulpice et al., 2009). Boldface italic type and underlined lightface italic type distinguish metabolites negatively and positively correlated to biomass, respectively, in Arabidopsis (Meyer et al., 2007; Sulpice et al., 2009).
c
Correlations were calculated from residual data (P < 0.05). The original data are in Supplemental Table S8.
