Transcriptomic analysis of the exogenous WOX peptide treatment on leaves and stems in E. urophylla × E. grandis DH32-29 genotype. (A) Principal coordinate analysis (PCoA) of the transcriptome analysis of leaf and stem after WOX peptide treatment. Each data point refers to one time point of sampling from 5 individual plants. S, stem; L, leaf; con, control/CK; pw5, WOX peptide 5. (B) Sample clustering analysis. (C) Cloud-rain diagram shows discreteness of the FPKM values. The expression values were log2 (FPKM + 1) transformed. (D) Nine-quadrant diagram shows the correlation between different samples. pc, Pearson Correlation. (E) Cluster analysis of DEGs in all samples. (F) DEGs in different combination. D, down-regulated; U, up-regulated
