Chromosomal location and phylogenetic tree analysis of CaWRKY family members. a All identified 72 WRKYs from Capsicum annuum (CaWRKYs) were mapped to the ‘CM334’ chromosomes in the pepper genome database using BLASTn. The MapInspect software (http://mapinspect.software.informer.com/) was used to map the gene locus on chromosomes. b A multiple alignment of the 72 CaWRKYs and 71 AtWRKYs from Arabidopsis thaliana was performed using ClustalX2 (http://www.clustal.org/clustal2/). The alignment result was used to construct a phylogenetic tree using the neighbor-joining method of PhyML software (http://www.atgc-montpellier.fr/phyml/)
