A novel transcription factor called ARF1 is shown to interact with synthetic auxin-response elements and function as a transactivator. ARF1 contains two domains (III and IV) found in another family of auxin response proteins called Aux/IAA, suggesting that regulation of diverse auxin response genes involves related proteins.

An important paper because it demonstrates the potential for multiple pairwise interactions between members of the Aux/IAA and ARF families of proteins. The complexity of auxin response may depend on the large numbers of homo- and heterodimers that can form.
