Figure 2.

The phylogenetic relationship, gene structure and motif composition analysis of the LBD gene family in Eucalyptus grandis. (a) The amino acid sequences of the EgLBD proteins were aligned with Clustal X, and the phylogenetic tree was constructed using the neighbour‐joining method in MEGA5; the scale bar represents 0.1 substitutions per amino acid, and the branches of different classes were painted with different colours (the blue branches represents class I, the red branches represents class II). (b) Exon/intron structures of the EgLBD genes, the exons, introns and UTR are represented by the green boxes, black lines and blue boxes, respectively, and the scale bar represents 1 kb. (c) Conserved motif of EgLBD proteins, different motifs are represented by different coloured boxes with number 1–20, and the scale bar represents 50 aa (amino acid).
