Functional Description ? help Back to Top
Source	Description
TAIR	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.
UniProt	Auxin response factors (ARFs) are transcriptional factors that bind specifically to the DNA sequence 5'-TGTCTC-3' found in the auxin-responsive promoter elements (AuxREs). Act as a transcriptional activator of several tropic stimulus-induced (TSI) genes, including SAUR50. Formation of heterodimers with Aux/IAA proteins may alter their ability to modulate early auxin response genes expression. Required for differential growth responses of aerial tissues. Involved in ethylene responses. Regulates lateral root formation through direct regulation of LBD16 and/or LBD29. Functionally redundant with ARF19. Mediates embryo axis formation and vascular tissues differentiation. Functionally redundant with ARF5. {ECO:0000269\|PubMed:12036261, ECO:0000269\|PubMed:14973283, ECO:0000269\|PubMed:16371470, ECO:0000269\|PubMed:16461383, ECO:0000269\|PubMed:17259263}.

ARF7 plays a major role in regulating expression of a subset of auxin response genes in leaf mesophyll cells. [PMID: 15923351] Mutations in ARF19 have little effect on their own, but in combination with mutations in NPH4/ARF7, encoding the most closely related ARF, they cause several phenotypes. [PMID: 15960621] ARF7 acts to regulate the auxin-mediated transcription of LATERAL ORGAN BOUNDARIES-DOMAIN16/ASYMMETRIC LEAVES2-LIKE18 (LBD16/ASL18) and/or LBD29/ASL16 in roots. [PMID: 17259263] Reduced upregulation of glycolipid synthase and phospholipase genes in these mutants under Pi-deficient conditions indicates that IAA14 and ARF7/19 affect membrane lipid remodeling at the level of transcription. [PMID: 20043234] Mutations affecting either ARF7 or ARF19 function almost fully blocked manifestation of the sar1-7-dependent ethylene hypersensitivity phenotype. [PMID: 22238449] Brassinosteroids employs auxin signaling components IAA19 and ARF7 to modulate the specific downstream processes. [PMID: 23125315] Data indicate that PIF4 and PIF5 negatively regulate auxin signaling. that PIF4 and PIF5 negatively modulate auxin-mediated phototropism through directly activating IAA19 and IAA29, which physically interact with auxin factor7 (ARF7). [PMID: 23757399] Data indicate that CARBON-METABOLISM INVOLVED (GNC) and GNC-LIKE (GNL)/CYTOKININ-RESPONSIVE GATA FACTOR1 (CGA1) expression is repressed by AUXIN RESPONSE FACTO ARF2 and ARF7. [PMID: 23878229] phosphorylation of ARF7 and ARF19 by BRASSINOSTEROID-insensitive2 (BIN2) can also potentiate auxin signalling output during lateral root organogenesis. [PMID: 24362628] the thermodynamic and structural basis for Arabidopsis thaliana ARF7 PB1 domain self-interaction. [PMID: 25839233] Analyses of the expression pattern of ARF7 and ARF5 targets suggest that this patterning mechanism controls flanking and central zone specification in Arabidopsis LR primordia. [PMID: 25944102] ARF7 and FLP transcription factors jointly form a coherent feed-forward motif that mediates the auxin-responsive PIN3 transcription in planta to steer the early steps of lateral root formation. [PMID: 26578065] Transcription factors AUXIN RESPONSE FACTOR7 (ARF7) and ARF19 mutants showed down-regulated expression of PHOSPHATE STARVATION RESPONSE1 (PHR1) and downstream Pi starvation-induced genes in roots. [PMID: 30026290] Epistatic interaction of NPH4 and IAR2 genes in Arabidopsis roots has been reported. [PMID: 30484609] hydropatterning is dependent on auxin response factor ARF7 [PMID: 30573626]
