Figure 7From: Genome-wide analysis of WRKY gene family in Cucumis sativusPairwise comparisons of the expression profiles of putative orthologous cucumber and Arabidopsis WRKY genes under abiotic stresses. The relative expression of CsWRKY genes was obtained by real-time RT-PCR (indicated by triangles). Data are the means of three replicates with standard errors represented by bars. The CsWRKY expression data were compared with the mean-normalized expression data for their putative orthologous AtWRKY genes from a publicly available Arabidopsis microarray data set (indicated by circles) according to the description in Methods. The relative amount of mRNA (y-axis) was the ratio of treated to untreated sample. The treatment time (h) under the particular abiotic stress is presented on the x-axis. R indicates the correlation coefficient for expression between orthologs under the corresponding abiotic stresses. A distinct positive correlation was detected in most orthologs (A-D), but no obvious correlation was detected in group 3 orthologs (E-F). A negative correlation was detected in a small number of orthologs (G-H).Back to article page
