Levels of biosynthetic intermediates and free auxin in Arabidopsis thaliana plants cultivated on NO3 (control) or NH4+ as the only nitrogen source. Content of anthranilate (ANT; A), tryptophan (Trp; B), indole-3-acetamide (IAM; C), indole-3-acetonitrile (IAN; D), indole-3-pyruvic acid (IPyA; E), and indole-3-acetic acid (IAA; F) in leaves and roots. Means are given with their SD (n = 10). Asterisks represent significant differences between NO3 versus NH4+- derived tissues (P < 0.05)
