Quantitative RT-PCR of 14 candidate genes under heat stress, chilling stress, and control conditions. A-N: represents the expression pattern of HSFA6B, DREB7, DREB8, PETA, PETB, PETM, ATPA, PGLP1, GOX1, GOX2, GOX3, HSP81.4, Lhcb6 and JAZ6 genes respectively. Transcript levels are normalized to PtACTIN and error bars represent standard error. The control group consisted of three biological samples that were exposure to room temperature under light (25°C, 6 h, 1250 μmolm-2s-1PPFD). Heat stress indicates samples treated at high temperature under light (42°C, 6 h, 1250 μmolm-2s-1PPFD). Chilling stress indicates three biological samples that were treated at low temperature under light (4°C, 6 h, 1250 μmolm-2s-1PPFD) (4°C, 6 h) (‘*’represents P-value < 0.05; ‘**’ represents P-value < 0.01).
