Soil salinity is one of the most commonly encountered environmental stresses affecting plant growth and crop productivity. Accordingly, plants have evolved a variety of morphological, physiological and biochemical strategies that enable them to adapt to saline growth conditions. For example, it has long been known that salinity-stress increases both the production of the gaseous stress hormone ethylene and the in planta accumulation of reactive oxygen species (ROS). Recently, there has been significant progress in understanding how the fine-tuning of ethylene biosynthesis and signaling transduction can promote salinity tolerance, and how salinity-induced ROS accumulation also acts as a signal in the mediation of salinity tolerance. Furthermore, recent advances have indicated that ethylene signaling modulates salinity responses largely via regulation of ROS-generating and ROS-scavenging mechanisms. This review focuses on these recent advances in understanding the linked roles of ethylene and ROS in salt tolerance.
土壤盐渍化是影响植物生长和作物生产力的最常见环境胁迫之一。因此，植物进化出了多种形态、生理和生化策略，使其能够适应盐渍生长条件。例如，长期以来人们都知道盐胁迫会增加气态胁迫激素乙烯的产生以及活性氧（ROS）在植物体内的积累。最近，在理解乙烯生物合成和信号转导的微调如何促进耐盐性，以及盐诱导的ROS积累如何在耐盐性介导中也作为一种信号方面取得了重大进展。此外，最近的研究进展表明，乙烯信号主要通过调节ROS产生和ROS清除机制来调节盐响应。本综述重点关注在理解乙烯和ROS在耐盐性中的关联作用方面的这些最新进展。
