Fig. 5From: A systematical genome-wide analysis and screening of WRKY transcription factor family engaged in abiotic stress response in sweetpotatoInter-chromosomal relations of IbWRKY genes in sweetpotato chromosomes. 15 chromosomes are indicated by different colors. The gene density is displayed using a heatmap. The synteny IbWRKY gene pairs in different chromosomes are marked with colored curvesBack to article page
