Molecular basis for AUXIN RESPONSE FACTOR protein interaction and the control of auxin response repression.
In plants, the AUXIN RESPONSE FACTOR (ARF) transcription factor family regulates gene expression in response to auxin. In the absence of auxin, ARF transcription factors are repressed by interaction with AUXIN/INDOLE 3-ACETIC ACID (Aux/IAA) proteins. Although the C termini of ARF and Aux/IAA proteins facilitate their homo- and heterooligomerization, the molecular basis for this interaction rema...
متن کاملThe PB1 domain in auxin response factor and Aux/IAA proteins: a versatile protein interaction module in the auxin response.
An integral part of auxin-regulated gene expression involves the interplay of two types of transcription factors, the DNA binding auxin response factor (ARF) activators and the interacting auxin/indole acetic acid (Aux/IAA) repressors. Insight into the mechanism of how these transcription factors interact with one another has recently been revealed from crystallographic information on ARF5 and ...

متن کاملAuxin Response Factors: output control in auxin biology.
The phytohormone auxin is involved in almost all developmental processes in land plants. Most, if not all, of these processes are mediated by changes in gene expression. Auxin acts on gene expression through a short nuclear pathway that converges upon the activation of a family of DNA-binding transcription factors. These AUXIN RESPONSE FACTORS (ARFs) are thus the effector of auxin response and ...
متن کاملActivation and repression of transcription by auxin-response factors.
Auxin-response factors (ARFs) bind with specificity to TGTCTC auxin-response elements (AuxREs), which are found in promoters of primary/early auxin-response genes. Nine different ARFs have been analyzed for their capacity to activate or repress transcription in transient expression assays employing auxin-responsive GUS reporter genes. One ARF appears to act as a repressor. Four ARFs function as...
