Abstract:

Chloroplasts are the key organelles responsible for photosynthesis in plants. As semi-autonomous structures unique to plant cells, their development is regulated by both internal growth and developmental signals as well as external environmental cues. Among these factors, temperature plays a critical role in shaping chloroplast development. It influences various aspects, such as the chloroplast membrane system, morphology, plastid division, and differentiation, ultimately impacting their development and function. This review begins with a concise overview of the structure, function, and developmental processes of chloroplasts in response to temperature fluctuations. It then summarizes research progress on plant leaf color mutants, shedding light on the molecular basis of temperature regulation in chloroplast development. Additionally, the review explores the mechanisms of temperature regulation in chloroplasts across three levels: Transcriptional regulation of chloroplast genes, post-transcriptional regulation of chloroplast genes, and protein synthesis and homeostasis in chloroplast. Finally, it discusses future directions, offering insights into how leaf color-related genes can be leveraged to uncover the mechanisms underlying temperature-responsive chloroplast development, with applications in both research and agricultural practices. In conclusion, this review thoroughly examines how environmental temperature changes affect chloroplast development and physiological functions in crops, while also exploring the broader implications for photosynthesis. By addressing these impacts, it aims to provide theoretical insights and practical guidance for developing molecular breeding strategies that enhance crop adaptability and photosynthetic efficiency in the face of global climate change.
