Two other ARF genes, NPH4/ARF7 and ARF19, were also induced by senescence, and mutations in these genes enhanced arf2 phenotypes.

In addition, we demonstrated that expression of mIAA14-GR under either the ARF7 or the ARF19 promoter also suppressed LR formation as in the arf7 arf19 double mutants, and that IAA14 interacted with ARF7 and ARF19 in yeasts.

In the yeast two-hybrid system, IAA18 interacts with AUXIN RESPONSE FACTOR 7 (ARF7) and ARF19, transcriptional activators that positively regulate lateral root formation.

Plant Cell Physiol. 2006 Aug;47(8):1095-101. Epub 2006 Jul 18.


We transiently expressed the C-terminal protein-protein interaction domains (CTDs) of Arabidopsis ARFs, MP/ARF5 and NPH4/ARF7, and MSG2/IAA19, fused to fluorescent proteins in HeLa cells, and determined their molecular interactions with fluorescence cross-correlation spectroscopy (FCCS).

Here, interaction assays, expression studies and combinations of multiple loss- and gain-of-function mutants were used to assess the roles of two ARFs, NONPHOTOTROPIC HYPOCOTYL 4 (NPH4/ARF7) and MONOPTEROS (MP/ARF5), in Arabidopsis development.
Finally, we demonstrate antagonistic interaction between ARF and Aux/IAA gene functions in Arabidopsis development.

A synergistic genetic interaction was demonstrated between MYB77 and ARF7 that resulted in a strong reduction in lateral root numbers.

Because IAA20 and IAA30 were early auxin-inducible and were expressed in the root apical meristem, they may have a physiological role in maintaining the stem cell niche of root, by keeping the activity of MP/ARF5 and NPH4/ARF7 at an acceptable level.
