Rice (Oryza sativa L.) is an important food crop, but its production faces severe challenges due to climate change, especially fluctuations in temperature and light. This study explores the mechanisms by which rice senses and adapts to these environmental changes. High temperatures adversely affect rice growth and yield, so understanding the mechanisms of heat tolerance is of great significance. Studies have identified key genes and pathways involving auxin and abscisic acid (ABA), which play an important role in rice's response to heat stress. In addition, RNA modifications such as 5-methylcytosine (m5C) improve rice's ability to adapt to high temperatures by stabilizing photosynthesis and detoxification systems. The interaction between light and circadian rhythms also significantly affects rice's response to temperature stress, and certain specific genes improve rice's cold tolerance by coordinating these responses. This study integrates current research on the molecular, genetic, and physiological responses of rice to temperature and light stress, and provides potential breeding strategies for cultivating rice varieties with strong stress resistance.
