Phylogenetic relationships of the CBL and CIPK genes. a Numbers of gene members from CBL and CIPK families in studied genomes. Red box on branch of species tree represents the whole genome duplication event. PWGD: the ancestral Papilionoideae whole-genome duplication event. The gene number was calculated at the haploid genome level (one set of chromosomes) of each species. 2 × : diploid, 4 × : tetraploid. b The phylogeny of CBL gene family. c The phylogeny of CIPK family. Branches in different colors indicate different taxa groups
