CPSC Lecture with Prof. Christine H. Foyer

Reactive oxygen species (ROS) are important signalling molecules in plants that play a crucial role in plant growth, development and stress responses. ROS production and processing are tightly regulated to regulate cellular redox homeostasis and facilitate oxidative signalling. This talk will cover the considerable progress that has been made in our understanding of ROS sensing and signalling pathways in recent decades, while highlighting the significant gaps that remain in current knowledge. For example, oxidation of the nucleus in response to environmental stresses is a widespread, yet poorly documented, phenomenon. This talk will consider the potential mechanisms of ROS processing in the nucleus, using the example of catalase as an enzyme that can be relocated to different cellular compartments. Recent developments in systemic signalling will be highlighted, together with how they might be used to increase plant resilience to environmental stress.
