CDF3 effects on Arabidopsis plants growth under different N conditions. Phenotypes and biomass measurements of Col-0, cdf3-1, cdf3-2, and CDF3 overexpressor plants (Lines 2.1 and 5.4) on MS medium containing different concentrations of potassium nitrate as sole nitrogen source. Biomass was measured as dry weight per plant. The photographs and biomass measurements were obtained after 12 days after treatment. (A) Shoot and (B) root dry weight (DW) of 12-day-old plants WT (Col-0), and CDF3 gain- and loss-of-function lines grown under different nitrate conditions (1 and 10 mM KNO₃). Values are the mean ± SE of three independent replications each containing 20 plants per genotype. (C) Shoot-root DW ratio. Asterisks indicate significant differences compared with wild-type (Col-0; p < 0.05); analysis of variance Student-Newman-Keuls tests. (D) Representative pictures of the analyzed plants.
