CRY amino acid sequences from 14 diverse plant species were obtained from the NCBI database. The alignment was constructed using ClustalX and the phylogenetic tree was constructed using the neighbor-joining method of MEGA version 4.1 software. Each node corresponds to a number indicating the bootstrap value for 1000 replicates. The scale bar represents 0.05 substitutions per sequence position. PeCRY1 is denoted by a red dot.
