Gene structure of WRKY in I. trifida. The evolutionary tree of ItfWRKY genes was constructed using MEGA7 and shown on the left. Schematic of exon/intron structure was displayed by the Gene Structure Display Server ( The exons, introns and UTRs are represented by red solid boxes, black lines and blue boxes, respectively
