Fig. 5From: Genome-wide identification and analysis of WRKY gene family in maize provide insights into regulatory network in response to abiotic stressesHierarchical clustering of expression profiles of ZmWRKY gene family in 10 tissues. Ten tissues from different developmental stages including endosperm, husk, tassel, leaf, silks, shoot tip, stem, seedling, root and seed were investigated .The expression values were shown as log2 of the RPKM values. The scale bar is shown in the middle and higher expression levels are presented as red colorBack to article page
