ARFs bind to the cis element 5'-TGTCTC-3' ARFs mediate changes in gene expression in response to auxin. ARF's form heterodimers with IAA/AUX genes. ARF1 enhances mutant phenotypes of ARF2 and may act with ARF2 to control aspects of maturation and senescence.ARF1:LUC and 3xHA:ARF1 proteins have a half-life of ~3-4 hours and their degradation is reduced by proteasome inhibitors. 3xHA:ARF1 degradation is not affected by a pre-treatment with IAA. A nuclear-targeted fusion protein containing the middle region of ARF1 linked to LUC:NLS has a similar half-life to the full-length ARF1:LUC construct. The degradation of 3xHA:ARF1 is not affected in an axr6-3 mutant grown at room temperature, although the degradation of AXR2/IAA7 is slowed under these conditions.no obvious auxin-related growth phenotype arf1-3 arf2-6 double mutant; similar but much stronger phenotype than arf2 single mutants; homozygous double mutant is sterile; large leaves; long, thick and wavy inflorescence stem; abnormal flower morpholoy; delayed flowering; delayed senescence.

The ETTIN gene encodes a protein with homology to DNA binding proteins which bind to auxin response elements. ETT transcript is expressed throughout stage 1 floral meristems and subsequently resolves to a complex pattern within petal, stamen and carpel primordia. ETT probably functions to impart regional identity in floral meristems that affects perianth organ number spacing, stamen formation, and regional differentiation in stamens and the gynoecium. During stage 5, ETT expression appears in a ring at the top of the floral meristem before morphological appearance of the gynoecium, consistent with the proposal that ETT is involved in prepatterning apical and basal boundaries in the gynoecium primordium. It is a target of the ta-siRNA tasiR-ARF. ETT is also a target of AP2; integrateing the functions of AGAMOUS and APETALA2 in floral meristem determinacy.Unusual gynoecium and floral patterning defects, including an increased number of sepals and carpels. very strong allele;homozygotes have flowers with 1-2 extra sepals and petals, 1 less medial stamen and a gynoecium with altered shape and anatomy; locule number on medial stamen is often reduced; gynoecium has a reduced ovary which is covered abaxially by style transmitting tract apically, and style epidermal tissue basally; it appears as if the top of the gynoecium has been pulled down over the surface of the ovary, and the bottom of the gynoecium has been pulled up, creating an elongated internode-like basal stalk; ovule density is not affected but placentae are shortened; ovules appear sterile due to failure of integument growth around egg sac which protrudes out of the ovule tip and appears to lack the full compliment of 8 nuclei; pollen is fertile weak allele; homozygotes have flowers with 1-2 extra sepals and petals, 1 less medial stamen and a gynoecium with altered shape and anatomy; locule number on medial stamen is often reduced; gynoecium has a slightly reduced ovary, with a small basal internode, and the basalization of the adaxial style tissue only on the medial sides of the gynoecium; almost fully female fertile intermediate allele; homozygote has flowers with 1-2 extra sepals and petals, 1 less medial stamen and a gynoecium with altered shape and anatomy; locule number on medial stamen is often reduced; gynoecium has a reduced ovary which is covered abaxially by style transmitting tract apically, and style epidermal tissue basally; it appears as if the top of the gynoecium has been pulled down over the surface of the ovary, and the bottom of the gynoecium has been pulled up, creating an elongated internode-like basal stalk; ovule density is not affected but placentae are shortened; ovules appear sterile due to failure of integument growth around egg sac which protrudes out of the ovule tip and appears to lack the full compliment of 8 nuclei; pollen is fertile. Short internodes, abnormal phyllotaxy, misshapen floral organs, variable floral organ numbers, gynoecium lacks valve tissue, , abnormally positioned ovules. Resembles kanadi homozygous mutants. The gynoecia of double mutants showed severe reduction of the ovary and morphological abnormalities in the apical region that were similar to ett strong allele mutant phenotypes. Occasionally, inflorescences of the double mutant failed to produce any normal flower buds, resulting in pin-like structures that were not found in either stv1 or ett single mutants. Pin-like inflorescences are formed in mp, pid, and pin1 mutants and in wild-type plants treated with polar auxin transport inhibitors. The gynoecial defects of ett-1 mutants, such as reduction in ovary size and increased gynophore elongation, were enhanced by the sty1-1 mutation. A number of double mutant gynoecia were nearly completely valveless, and in those, ovules grew on top of a placental surface. In addition, the apical ends of sty1-1 ett-1 gynoecia were less fused than those of ett-1 and sty1-1, and ovules frequently protruded at the apex. The amount of stylar and stigmatic tissues was reduced compared with ett-1, and the double mutant was sterile. As in ett-1 gynoecia, ectopic tissue of transmitting tract identity was generally present.

The protein interacts with IAA1 (yeast two hybrid) and other auxin response elements such as ER7 and ER9 (yeast one hybrid). ARF19 protein can complement many aspects of the arf7 mutant phenotype and , together with ARF7, 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.The primary roots of the mutant produce as many lateral roots as the wild type.

The ETTIN gene encodes a protein with homology to DNA binding proteins which bind to auxin response elements. ETT transcript is expressed throughout stage 1 floral meristems and subsequently resolves to a complex pattern within petal, stamen and carpel primordia. ETT probably functions to impart regional identity in floral meristems that affects perianth organ number spacing, stamen formation, and regional differentiation in stamens and the gynoecium. During stage 5, ETT expression appears in a ring at the top of the floral meristem before morphological appearance of the gynoecium, consistent with the proposal that ETT is involved in prepatterning apical and basal boundaries in the gynoecium primordium. It is a target of the ta-siRNA tasiR-ARF. ETT is also a target of AP2; integrateing the functions of AGAMOUS and APETALA2 in floral meristem determinacy.Unusual gynoecium and floral patterning defects, including an increased number of sepals and carpels. very strong allele;homozygotes have flowers with 1-2 extra sepals and petals, 1 less medial stamen and a gynoecium with altered shape and anatomy; locule number on medial stamen is often reduced; gynoecium has a reduced ovary which is covered abaxially by style transmitting tract apically, and style epidermal tissue basally; it appears as if the top of the gynoecium has been pulled down over the surface of the ovary, and the bottom of the gynoecium has been pulled up, creating an elongated internode-like basal stalk; ovule density is not affected but placentae are shortened; ovules appear sterile due to failure of integument growth around egg sac which protrudes out of the ovule tip and appears to lack the full compliment of 8 nuclei; pollen is fertile weak allele; homozygotes have flowers with 1-2 extra sepals and petals, 1 less medial stamen and a gynoecium with altered shape and anatomy; locule number on medial stamen is often reduced; gynoecium has a slightly reduced ovary, with a small basal internode, and the basalization of the adaxial style tissue only on the medial sides of the gynoecium; almost fully female fertile intermediate allele; homozygote has flowers with 1-2 extra sepals and petals, 1 less medial stamen and a gynoecium with altered shape and anatomy; locule number on medial stamen is often reduced; gynoecium has a reduced ovary which is covered abaxially by style transmitting tract apically, and style epidermal tissue basally; it appears as if the top of the gynoecium has been pulled down over the surface of the ovary, and the bottom of the gynoecium has been pulled up, creating an elongated internode-like basal stalk; ovule density is not affected but placentae are shortened; ovules appear sterile due to failure of integument growth around egg sac which protrudes out of the ovule tip and appears to lack the full compliment of 8 nuclei; pollen is fertile. Short internodes, abnormal phyllotaxy, misshapen floral organs, variable floral organ numbers, gynoecium lacks valve tissue, , abnormally positioned ovules. Resembles kanadi homozygous mutants. The gynoecia of double mutants showed severe reduction of the ovary and morphological abnormalities in the apical region that were similar to ett strong allele mutant phenotypes. Occasionally, inflorescences of the double mutant failed to produce any normal flower buds, resulting in pin-like structures that were not found in either stv1 or ett single mutants. Pin-like inflorescences are formed in mp, pid, and pin1 mutants and in wild-type plants treated with polar auxin transport inhibitors. The gynoecial defects of ett-1 mutants, such as reduction in ovary size and increased gynophore elongation, were enhanced by the sty1-1 mutation. A number of double mutant gynoecia were nearly completely valveless, and in those, ovules grew on top of a placental surface. In addition, the apical ends of sty1-1 ett-1 gynoecia were less fused than those of ett-1 and sty1-1, and ovules frequently protruded at the apex. The amount of stylar and stigmatic tissues was reduced compared with ett-1, and the double mutant was sterile. As in ett-1 gynoecia, ectopic tissue of transmitting tract identity was generally present.

Adult double mutant plants have thin and short inflorescence stems, and their rosette leaves are small and epinastic. In addition, it has reduced numbers of inflorescence stems, suggesting enhanced apical dominance. By contrast, its flowers appear to be normal, and they fertilize normally. The double mutant mutant displays agravitropic responses in both hypocotyls and roots. When seedlings are grown vertically under dark conditions, the regulation of growth orientation is disrupted in both hypocotyls and roots, with the hypocotyls occasionally growing downward and the roots upward. Also, the roots and hypocotyls of the double mutant show reduced gravitropic curvatures compared with the wild type when vertically dark-grown seedlings are reoriented by 90°. The phenotype of the double mutant is most obvious at its seedling stage, with its most prominent phenotype being severely impaired lateral root formation.
