Abstract: Photosynthesis taking place in chloroplasts is the foundation for the transformation of matter and energy in nature and the cornerstone for the survival and development of human society. Recent studies have shown that chloroplasts are also environmental receptors, capable of converting external environmental changes into internal reactive oxygen species signals. By activating the retrograde signal transduction process from chloroplasts to the nucleus, they regulate nuclear gene expression and mediate stress responses. This report mainly elaborates on the molecular mechanisms of the generation, perception, signal transduction and tolerance of reactive oxygen species in chloroplasts. Plants respond to environmental changes and enhance their adaptability to environmental adversity through a series of complex physiological and biochemical responses.
