The significance and functions of ethylene in flooding stress tolerance in plants

摘要: Abstract Climate change has increased the global environmental risks, especially impacts of abiotic stresses on agriculture productivity. Among aggravated by climate change, flooding (complete submergence, stagnant flooding, soil waterlogging) been identified as a major stress for plant growth and food production worldwide. Improving crop plants adaptation to conditions is important cope with increasing incidences intensity which could potentially be accomplished through manipulating adaptive physiological molecular processes. Ethylene key hormone in modulating signaling, metabolic responses. Significant progress was made understanding basic mechanisms associated ethylene-mediated responses stress, though our knowledge this field still far from complete. This review provided (a) an overview ethylene biosynthesis, signaling its perception under flood condition plants, emphasis rice; (b) assess functions based available evidences; (c) cross-talks other phytohormones molecules ethylene-induced responses; (d) elucidate role mediated tolerance pathways aim developing tolerant plants. The represents step forward develop resilient exploiting biology functions.
