Scientists find a molecular clue to the complex mystery of auxin signaling in plants

Plants fine-tune the response of their cells to the potent plant hormone auxin by means of large families of proteins that either step on the gas or put on the brake in auxin’s presence. Scientists at Washington University have learned that one of these proteins, a transcription factor, has an interaction region that, like a button magnet, has a positive and negative face. Because of this domain, the protein can bind two other proteins or even chains of proteins arranged back-to-front.
