Movie S1.

Molecular modeling view. The movie represents the crystal structure of TIR1 (Gray), IAA (red), and the DII domain of IAA7 (green). The first sequence shows the best docking probability obtained for RN1 (yellow), RN2 (purple), RN3 (cyan), RN4 (orange) and RN4-8 (pink). The second sequence shows two chosen molecules for RN1 (yellow), RN3 (cyan) and RN4 (orange), corresponding to the best docking conformation, next to the conformation which thermodynamically stabilized TIR1 without the DIIdomain of IAA7.
