Phenotype of Arabidopsis thaliana (Col-0) after 8 weeks of hydroponic culture in a solution containing 5 mM NO3 (control) or 5 mM NH4+ as the sole nitrogen source. A Visual comparison of plants and magnifications of roots under binocular (insert; scale bars = 1 mm). B Rosette diameter and primary root length. C Dry weight of leaves and roots. Means are given with their SD (n = 10). Asterisks represent statistically significant differences between NO3 versus NH4+-derived tissues (P < 0.05)
