Phylogenetic relations of the kinesins from C. lanatus, A. thaliana and O. sativa. The tree was calculated with MEGA6.06 software using neighbor-joining method. Neighbor joining phylogenetic tree of the kinesin family. This tree summarizes the evolutionary relationships among kinesins in watermelon based on the kinesin sequences from Arabidopsis and rice. The length of the branches is proportional to the amino acid variation rate. Watermelon possess 10 kinesin families, including kinesin-1,4, 5, 7, 8, 10, 11, 12, 13, 14 families. In addition, the kinesin-7 and kinesin-14 families are greatly expanded
