Chloroplast DNA repair in plants

Chloroplasts contain their own DNA, which is crucial for the organelle's function and for photosynthesis. However, chloroplast DNA (cpDNA) is susceptible to damage from various stressors, including UV radiation and oxidative stress. Plants possess sophisticated repair mechanisms to maintain the integrity of cpDNA, involving processes such as homologous recombination and base excision repair. The efficiency of these repair mechanisms is vital for chloroplast function and overall plant health. Recent studies have revealed the roles of specific proteins in chloroplast DNA repair, shedding light on potential strategies to enhance plant resilience to environmental stressors by targeting these pathways for crop improvement.
