The bioinformatic analysis of the transcriptome data of normal flowering and the CIR treatment. a The PCA analysis of the expression patterns of all the 96 samples at the 4 stages. In the legend, the first character indicated the name of the stage, which was same with Fig. 1a; the second character indicated the name of the group, the normal flowering group and the CIR group were indicated as C and T, respectively; the last character indicated the 4 types of tissue: T, the top of the branch; M, the middle part of the branch, at 1/2 of plant height; B, the basal part of the branch; R, the rhizome of each plant. Three biological replications were conducted. b the H-cluster analysis of the expression patterns of all the 96 samples at the 4 stages. The abbreviations were same as that of Fig. 2a. c The KEGG enrichment analysis. The schematic diagram in the top pattern indicated the different ways of KEGG analysis, which included the comparison between the groups of normal flowering and the CIR treatment, and the comparison within each group. In the schematic diagram, the direction of the arrow indicated the control samples. The numeric characters indicated the number of DEGs
