Effect of chilling on gene expression in the leaves of two maize hybrids. The 7-day chilling treatment (10 °C day/4 °C night) was applied at about the 6-VL stage. Analyses were performed at the end of the chilling treatment for treated plants or 1 day after the beginning of the treatment for control plants in order to compare plants at the same developmental stage. a Sampling procedure. b Relative expression levels quantified by RT-qPCR. Five genes were used for normalization. Data are means ± se of 3 technical replicates for one experiment; two replicate experiments are shown in Additional file 4: Figure S3. Gene abbreviations: ICE1 (INDUCER OF CBF/DREB EXPRESSION 1), DREB1 (DROUGHT-RESPONSIVE ELEMENT BINDING), CDKA1 (CYCLIN DEPENDENT KINASE A 1), CYCA3 (CYCLIN A 3), KRP1 (CYCLIN-DEPENDENT KINASE INHIBITOR 1), EXPA4 (ALPHA EXPANSIN 4), EXPB2 (BETA EXPANSIN 2), GGR (GERANYLGERANYL REDUCTASE), CAB1 (CHLOROPHYLL A/B BINDING PROTEIN), psbS (CP22 PSII subunit), VDE (VIOLAXANTHIN DE-EPOXIDASE), PEPC (PHOSPHOENOLPYRUVATE CARBOXYLASE), PPDK (PYRUVATE, ORTHOPHOSPHATE DIKINASE) and rbcS (RUBISCO small subunit)
