Abstract excerpt
The phytohormone auxin is a key developmental signal in plants. So far, only auxin perception has been described to trigger the release of transcription factors termed Auxin Response Factors (ARFs) from their auxin/indole-3-acetic acid (AUX/IAA) repressor proteins. Here, we show that phosphorylation of ARF7 and ARF19 by BRASSINOSTEROID-insensitive2 (BIN2) can also potentiate auxin signalling output during lateral...
