植物的生长发育过程以及对非生物和生物胁迫的适应都受到内源信号小分子的调控。其中，植物激素如气态烯烃、乙烯和活性氧（ROS）在介导许多特异性生长或细胞死亡反应中起重要作用。质外体活性氧由质膜呼吸爆发氧化酶同源蛋白产生，而细胞内活性氧主要产生于线粒体和叶绿体的电子传递链。乙烯在植物体内的积累是由于物理截留或乙烯生物合成的增强。在亚洲地区，水稻是一种必须承受高盐和重金属浓度洪水的主要作物。乙烯和活性氧被认为是介导水稻盐、铬和淹水胁迫的主要信号。这个小审查的重点是（i）什么是已知的乙烯和活性氧水平控制在这些非生物胁迫水稻，（ii）如何这两个信号介导的生长或死亡过程，（iii）反馈机制，反过来又调节乙烯和活性氧信号。
Plant growth and developmental processes as well as abiotic and biotic stress adaptations are regulated by small endogenous signaling molecules. Among these, phytohormones such as the gaseous alkene ethylene and reactive oxygen species (ROS) play an important role in mediating numerous specific growth or cell death responses. While apoplastic ROS are generated by plasma membrane-located respiratory burst oxidase homolog proteins, intracellular ROS are produced mainly in electron transfer chains of mitochondria and chloroplasts. Ethylene accumulates in plants due to physical entrapment or by enhanced ethylene biosynthesis. A major crop that must endure high salt and heavy metal concentrations upon flooding in regions of Asia is rice. Ethylene and ROS have been identified as the major signals that mediate salinity, chromium, and flooding stress in rice. This mini review focuses on (i) what is known about ethylene and ROS level control during these abiotic stresses in rice, (ii) how the two signals mediate growth or death processes, and (iii) feedback mechanisms that in turn regulate ethylene and ROS signaling.
