Transcriptional responses involved in auxin oxidation and conjugation in tissues of Arabidopsis thaliana plants grown on NO3− (control) or NH4+ as the only nitrogen source. Relative transcript levels of dioxygenase of auxin oxidation (DAO1-2; A); Gretchen Hagen 3 (GH3.1-6, 17) in leaves (B) and roots (C); UDP-glucose transferases (UTG74B1, UGT84B1, and UGT74D1; D). Transcript abundance values are normalized to the means of reference gene PP2A. Relative expression was set to 1 in control plants for reference. Means are given with their SD (n = 6). Asterisks represent significant differences between NO3− versus NH4+-derived tissues (P < 0.05)
