The seedlings grown on a dialysis membrane-covered agar plate encountered adequate mechanical impedance to the roots showed characteristic ethylene phenotypes. Detailed characterization of this phenotype suggested that ethylene signaling, rather than ethylene production plays a critical role in enhancing the ethylene response. We subsequently demonstrated that the enhanced ethylene response also affects the auxin response in root. Our results provide a new insight into the role of ethylene in changing root morphology during mechanical impedance.
