Research Topic:                                                                            

Plants have evolved complex signaling mechanisms that allow them to sense and respond to reactive oxygen species (ROS) generated during abiotic stresses.
In particular, chloroplasts naturally generate large amounts of ROS, including singlet oxygen (1O2), during photosynthesis.
This localized 1O2 can damage the chloroplast and can trigger quality control systems that lead to selective chloroplast degradation.
This raises an intriguing question; How do plants sense chloroplast dysfunction and selectively degrade damaged chloroplasts to sustain healthy chloroplast populations?
To answer this question, I am using a forward genetic approach to identify genes and pathways involved in 1O2-mediated chloroplast quality control and selective chloroplast degradation.
