Abstract: Global warming threatens food security, and rice is vulnerable to high temperatures, especially at reproductive stage. Plants perceive high temperatures and activate downstream responses in different levels, including disruptions in membrane fluidity, protein homeostasis and reactive oxygen species homeostasis. Rice responds to high temperature in different subcellular structures (cell membrane, endoplasmic reticulum, chloroplast) and different physiological and biochemical processes (nucleic acid, protein, metabolism). Natural alleles are more convenient for agricultural production, among which TT1 (Thermotolerance 1), TT2 and TT3 are three indispensable natural alleles conferring rice thermotolerance respectively via cytotoxic protein elimination, calcium signaling-mediated wax metabolism and membrane-chloroplast signaling. Therefore, it is of great significance to mine natural alleles of thermotolerance and clarify the mechanism of thermo-perception and thermo-responses, providing a theoretical basis for breeding thermotolerant varieties in crops.
