Overview of transcriptomes in Ws, CBF2-ox and CBF3-ox plants. (A) Venn diagram representing the total number of differentially expressed genes (DEGs) between CBF2-ox or CBF3-ox and Ws. CBF-ox up-regulated (log2 ≥ 1, FDR ≤ 0.01) or down-regulated (log2 ≤ -1, FDR ≤ 0.01) genes were shown. (B) Hierarchical cluster analysis of the DEGs. The heat-map was drawn with DEGseq of R package. (C) Verification of CBF regulon expression in Ws, CBF2-ox and CBF3-ox plants. Eight genes were selected for comparison of RNA-seq and qRT-PCR results. For RNA-seq data, ∗∗ represents FDR ≤ 0.01. The data of qRT-PCR were the means of three technical replicates ± SD (∗∗P ≤ 0.01; Student’s t-test). Three independent experiments were carried out with similar results.
