From: Comparative genomic analysis of the WRKY III gene family in populus, grape, arabidopsis and rice
Phylogenetic relationship of WRKY III proteins and the exon-intron structure of WRKY III genes From Populus, grape, Arabidopsis and rice. Left panel: an unrooted phylogenetic tree constructed using MEGA 6.0 by the N-J method. Clades of WRKY III genes (1–4) are highlighted with different colored backgrounds. Right panel: exon-intron structure. The exons and introns are indicated by green rectangles and thin lines, respectively. The untranslated regions (UTRs) are indicated by thick blue lines
