    ARF7; AUXIN RESPONSE FACTOR 7; AUXIN-REGULATED TRANSCRIPTIONAL ACTIVATOR 7; AUXIN-RESPONSIVE TRANSCRIPTIONAL ACTIVATOR 7; BIP; BIPOSTO; IAA21; IAA23; IAA25; indole-3-acetic acid inducible 21; indole-3-acetic acid inducible 23; indole-3-acetic acid inducible 25; MASSUGU 1; MSG1; NON-PHOTOTROPHIC HYPOCOTYL; T1M15.130; T1M15_130; TIR5; TRANSPORT INHIBITOR RESPONSE 5
    Summary
    Encodes an auxin-regulated transcriptional activator. Activates expression of IAA1 and IAA9 in the presence of auxin. Mutants affect blue light and gravitropic and auxin mediated growth responses. Together with AUX19, it is involved in the response to ethylene. In the arf7 arf19 double mutant, several auxin-responsive genes (e.g. IAA5, LBD16, LBD29 and LBD33) are no longer upregulated by auxin.
