Coordination of genome stability: Novel communication pathways between chloroplasts and other compartments in plant cells

Chloroplasts have their own genomes, as do the nucleus and mitochondria. Coordination between these genomic compartments in plant cells is crucial for plant development and adaptation to the environment. However, little attention has been paid to the coordination of genome stability in the chloroplast and other genomic compartments. Several recent studies have shed light on the regulatory mechanisms governing this coordination, demonstrating the importance of communication between the different genomes to maintain genome stability. Here we review the communication of genome stability between chloroplasts and other compartments in plant cells. We also discuss the challenges and opportunities in this exciting research area.
