FIGURE 7

Validation of differential expression of 10 universal genes using qRT-PCR. These genes are related to zeatin (Zm00001d032664), salicylic acid (Zm00001d034346), jasmonic acid (Zm00001d009714), gibberellin (Zm00001d038165), abscisic acid (Zm00001d010445), auxin (Zm00001d045203), ethylene (Zm00001d043247), hormone signal transduction (Zm00001d012660), heat shock protein (Zm00001d028408), and heat shock transcription factor (Zm00001d033987), respectively. T and S represent the heat-tolerant variety and the heat-sensitive variety, respectively. L represents the natural environment and H represents the heat-stressed environment. V9, V12, and VT represent the 9th leaf, 12th leaf, and tasseling stages. Vertical bars represent ± SD of the mean. a, b, c, and d indicate significant difference among different treatments (n = 3, P < 0.05).
