文摘

Auxin binds to TRANSPORT INHIBITOR RESPONSE 1 and AUXIN SIGNALLING F-BOX proteins (TIR1/AFBs) and promotes the degradation of Aux/IAA transcriptional repressors. The proteasome regulator PROTEASOME REGULATOR1 (PTRE1) has now been shown to be required for auxin-mediated repression of 26S proteasome activity, thus providing new insights into the fine-tuning of the homoeostasis of Aux/IAA proteins and auxin signaling.
