Source	Description
UniProt	Transcription factor (PubMed:23067202, PubMed:23603962). Represses the expression of protein phosphatases 2C in response to abscisic acid (ABA). Confers resistance to abiotic stresses dependent of ABA (PubMed:18162593, PubMed:9678577). In response to auxin, activates the transcription of the auxin-responsive gene IAA19. The IAA19 transcription activation by MYB44 is enhanced by direct interaction between MYB44 and PYL8 (PubMed:24894996). Transcriptional activator of WRKY70 by direct binding to its promoter region, especially at 5'-TAACNG-3' and 5'-CNGTTA-3' symmetric motifs (PubMed:23067202, PubMed:23603962). Activates salicylic acid (SA)- mediated defenses and subsequent resistance to biotrophic pathogen P.syringae pv. tomato DC3000, but represses jasmonic acid (JA)-mediated defenses responses against the necrotrophic pathogen A.brassicicola (PubMed:23067202). {ECO:0000269\|PubMed:18162593, ECO:0000269\|PubMed:23067202, ECO:0000269\|PubMed:23603962, ECO:0000269\|PubMed:24894996, ECO:0000269\|PubMed:9678577}.

The induction by JA is COI1-dependent (PubMed:23067202). {ECO:0000269\|PubMed:16463103, ECO:0000269\|PubMed:18162593, ECO:0000269\|PubMed:23067202}.
