Abstract

Rice (Oryza sativa) is an aerobic organism, for which oxygen shortage poses a serious problem. Longtime complete submergence leads to damage or even death of the plant. Submergence-tolerant rice adapts to flood (complete submergence) in a long time. Ethylene regulation networks and sugar signaling are involved in the submergence response of rice. This is mainly through the regulation of many key genes such as SUB1A and SK1/2; therefore, the level of abscisic acid (ABA) andgibberellic acid (GA) was regulated. This paper reviews these two signaling pathways, understanding which can help us develop new varieties and improve existing cultivars.

 

Key words: Rice, ethylene regulation networks, sugar signaling, submergence.
