Abstract: Plants can accept environment stimulation, specifically modulate gene expression, induce physiological responds, and adapt environment by complicated signal transduction. Reactive oxygen species (ROS) are versatile molecules mediating a variety of cellular responses in plant cells as an important signal molecule. ROS have been implicated as second messengers in several plant hormone responses. In this article, we review the role of ROS in phytohormone signal transduction.
