The WRKY Transcription Factor Genes in Lotus japonicus

Figure 4

Phylogenetic relationships and gene structure of Lotus japonicus WRKY domains. (a) Multiple alignments of WRKY domain amino acids executed by Clustal W and the phylogenetic tree constructed using MEGA 4.0 by the Neighbor-Joining (NJ) method with 1,000 bootstrap replicates. The red line indicated group IIx member. The percentage bootstrap scores higher than 50% were indicated on the nodes. (b) Exon-intron structures of WRKY domain genes from Lotus japonicus. Exons and introns were represented by green boxes and black lines, respectively. The number indicated introns phases. The sizes of exons and introns can be estimated using the scale at the bottom.
