Abstract
Sequestration of AUXIN RESPONSE FACTOR (ARF) transcription factors in cytoplasmic condensates represents a specialized mechanism for modulating cellular auxin responsiveness. In this issue of Developmental Cell, Xuan et al. show that MULTIPLE C2-DOMAIN AND TRANSMEMBRANE REGION PROTEIN (MCTP) proteins stimulate lateral root development by antagonizing ARF7 and ARF19 condensation.
