Phylogenetic relationships of canola CIPK proteins were compared with those from other species. The phylogenetic tree was based on the amino acid sequences of CIPK proteins from representative species. Protein sequences were aligned using ClustalX (v1.83) and a maximum parsimony tree was inferred using MEGA5.1. The percentage of replicate trees is shown on the branches and it is calculated in the bootstrap test (1000 replicates) for the associated taxa being clustered together.
