摘要
THE MIXED BLESSING OF ROS： DON＇T YOU KNOW THAT I＇M TOXIC？Due to plants＇ aerobic metabolism, reactive oxygen species （ROS） continuously accrue in different tissues and organs as a by-product of many metabolic reactions. Despite their toxic activity, plants also rely on ROS as a major form of second messenger to integrate, induce, and/or propagate biotic and abiotic signals and signaling cascades. Being small, short-lived, and rapidly diffusible makes ROS ideal messenger molecules for local biochemi- cal reactions. Hence, a delicate fine-tuning of localized ROS production and signaling events is crucial for many physi- ologic processes.
