Hierarchical clustering of gene expression levels determined using RNA-seq at different fiber development stages (a) and in different tissues (b). FPKM values of LuWRKYs were transformed by log10. S1, seedling stage; S2, fir like stage; S3, early fast growing stage; S4, fast growing stage; S5, bud stage; S6, flowering stage; S7, green stage; S8, maturity stage. Upper, middle, and lower third zones of stem, root, and leaf at late fast growing stage are designated SU, SM, SD, R, and L, respectively
