Phylogenetic tree of the WRKY proteins of pigeonpea (Cajanus cajan). The conserved WRKY domain sequences of pigeonpea WRKY proteins were used to construct multiple sequence alignments using Clustal W. Software MEGA was used to prepare the phylogenetic tree and neighbor-joining method was adopted by 1,000 bootstrap replications. The CcWRKY proteins of pigeonpea are classified into three groups, Group I–III, based on conserved WRKY domain sequences. Yellow colour indicates the Arabidopsis WRKY defense responsive genes used for selection of pigeonpea WRKY defense responsive genes.
