Functional Description ? help Back to Top
Source	Description
UniProt	Transcription factor that functions in salt stress response. Acts as negative regulator of NHX7/SOS1 and CBL4/SOS3 induction in response to salt stress (PubMed:23809151). In response to auxin, activates the transcription of the auxin-responsive gene IAA19. The IAA19 transcription activation by MYB73 is enhanced by direct interaction between MYB73 and PYL8 (PubMed:24894996). {ECO:0000269\|PubMed:23809151, ECO:0000269\|PubMed:24894996}.
