Analysis of relative expression levels of candidate genes and starch synthesis or degrading enzymes in high-temperature-sensitive and -tolerant lines under high-temperature stress and normal conditions. Analysis of candidate gene expression of rice in the flowering stage exposed to 42 °C in the growth chamber and sampling at various time points of 0, 5, 10, 15, 20, 25, 30, 35, 40, and 45 days after flowering. There was no significant difference in all genes under normal conditions, but there were significant differences in some genes in the high-temperature-tolerant and -sensitive lines under high-temperature treatment. CNDH11 is a high-temperature-sensitive line, and CNDH75 is a high-temperature-resistant line. * Significantly different at the 0.05 level. ** Significantly different at the 0.01 level
