Auxins is an essential phytohormone that regulates multiple aspects of plant growth and development. If it exerts a control at the transcriptional level, auxin is also involved in the regulation of translation. The team of Lyubov Ryabova has deciphered the molecular mechanisms of this regulation by revealing the missing link of the signaling pathway involved: the small auxin-activated ROP2 GTPase controls the action of the TOR kinase, a key regulator of translation. This work was published on 28 February 2017 in The EMBO Journal.
