Arabidopsis WT and nia1nia2 double mutant grown in 8-h SDs on soil or in hydroponics. On soil, plants were grown under 120 μmol.m^-2.s^-1 for 10 weeks. In hydroponics, plants were grown under 50 μmol.m^-2.s^-1 for 6 (WT) and 8 weeks (nia1nia2), on the 'standard' or ammonium-free solution. Bar = 20 mm.
