摘      要：The stress hormone ethylene plays a key role in plant adaptation to adverse environmental conditions.Nitrogen(N)is the most quantitatively required mineral nutrient for plants,and its availability is a major determinant for crop production.Changes in N availability or N forms can alter ethylene biosynthesis and/or signaling.Ethylene serves as an important cellular signal to mediate root system architecture adaptation,N uptake and translocation,ammonium toxicity,anthocyanin accumulation,and premature senescence,thereby adapting plant growth and development to external N status.Here,we review the ethylenemediated morphological and physiological responses and highlight how ethylene transduces the N signals to the adaptive responses.We specifically discuss the N-ethylene relations in rice,an important cereal crop in which ethylene is essential for its hypoxia survival.
