Fine-tuning of auxin homeostasis governs the transition from floral stem cell maintenance to gynoecium formation

Abstract

In Arabidopsis, the timing of floral meristem termination is determined by AGAMOUS. Here, the authors show that the CRC transcription factor, itself a direct target of AGAMOUS, coordinates meristem termination with subsequent gynoecium formation partly by repressing TRN2 expression and regulating auxin homeostasis.
