Figure 5

Heat-map of 65 differentially expressed genes involved in transcription factor, signal transport, stress kinase, defense/stress response, target protein compound in the cold response and acclimation of Lilium lancifolium . They were differentially expressed between the control 0 h, cold treatments 2 h and 16 h. The bar represents the scale of the expression levels for each gene (log₁₀ RPKM (number of reads per kilobase per million clean reads)) in the cold response and acclimation as indicated by green/red rectangles. Green indicates up-regulation of genes and Red indicates down-regulation and no change is indicated in black. Complete information for each gene list can be found in Additional file 1: Table S1.
