BcGRF8 improves plant growth under both ${\text{NO}}_3^{-}$ -rich and -poor conditions. (A) The phenotypes of 7-day-old WT and BcGRF8-overexpressing seedlings grown vertically on plates with medium containing different concentrations of ${\text{NO}}_3^{-}$ . Bar = 1 cm. (B) The expression levels of BcGRF8 in WT and BcGRF8-overexpressing Arabidopsis seedlings. The values are means ± SDs of three replications. (***P < 0.001 vs. WT). (C) The primary root lengths of 7-day-old plants grown under different ${\text{NO}}_3^{-}$ conditions. The error bars indicate standard deviations (SDs) of biological triplicates (**P < 0.01). (D) The phenotypes of 20-day-old WT and BcGRF8-overexpressing seedlings grown on plates with medium containing different concentrations of ${\text{NO}}_3^{-}$ . (E, F) Shoot (E) and root (F) FWs of 20-day-old seedlings grown under different ${\text{NO}}_3^{-}$ conditions. The values are means ± SDs of three replications. (**P < 0.01 vs. WT).
