Transcriptional analysis of Ailsa Craig fruit in response to cold storage. (A) Box plot of relative expression of six classes of DEGs. RPKM at day 0 was set as 1. The number of genes in each group is shown in parentheses. (B) Expression of CBF genes in response to cold storage. Blue bar: day 0, red ripe tomato fruit at harvest; green bar: C8d, 8 d of cold storage; red bar: C7dS1, 7 d of cold storage followed by one day recovery at 20 °C. Significant differences (FDR < 0.05) are denoted by different letters. Error bars indicate means ± SE; three biological replicates.
