Transcriptional patterns of the induced WRKY family members in pepper during P. capsici infection. These up-regulated CaWRKY genes can be mainly separated into three subgroups: early response (3 h-up), mid response (24 h-up), and mid-late response (ML-up) genes in (a) CM334 and (b) EC01. The transcriptional patterns of the three subgroup WRKY members in CM334 and EC01 are showed in (c) and (d), respectively. The Z-scores of RNA-seq data sets were used for analysis of gene expression patterns using the ggplot2 package (https://cran.r-project.org/web/packages/ggplot2/)
