Evidence for the control of Arabidopsis gynoecium morphogenesis by ETTIN via cell wall dynamicsAbstract: ETTIN is an atypical member of the AUXIN RESPONSE FACTOR family of transcription factors, which plays a crucial role in tissue patterning in the Arabidopsis thaliana gynoecium. Though recent insights have provided valuable information on ETT's interactions with other components of auxin signaling, the biophysical mechanisms linking ETT to its ultimate effects on gynoecium morphology were until now unknown.
