We investigate how plants regulate ROS production and scavenging in response to environmental stresses, including high temperature, drought, and excess light. We are particularly interested in how ROS and redox signals crosstalk with other signals, such as phytohormones, and integrate with cellular and physiological processes to regulate acclimation and stress tolerance.
