Expression of the COR genes over 24 hours in the cold. Expression of COR6.6, COR15a, COR15b, COR47, COR78. RNAs were the same as those used in Fig. 3. PCR was performed on the ABI7900HT platform. For each gene, seven accessions were analyzed by Q-PCR: 157 AV (Ita-0), 163 AV (Can-0), 166 AV (Cvi-0), 186 AV (Col-0), 229 AV (Rld-2), 231 AV (Rub-1), and 233 AV (Sah-0). Sensitive accessions are in red and tolerant ones in blue. Time points shown are 1 h, 3 h, 6 h and 24 h after transfer to 5°C. Average standard errors in the determination of the expression of the different genes varied between 0.15 Ct and 0.85 Ct.
