Phytohormone ethylene plays essential roles in plant growth and development and response to stresses. In dicot Arabidopsis, the ethylene signaling pathway has been well-characterized. Ethylene signal is perceived and transduced through an ethylene receptor-CTR1-EIN2-EIN3/EIL1 pathway. In semiaquatic monocot rice, while ethylene plays essential roles in its adaptive responses to the hypoxia conditions and regulates multiple agronomic traits, its signaling mechanism is largely unclear.
