Fig. 3From: Characterization of a novel Helitron family in insect genomes: insights into classification, evolution and horizontal transferPhylogenetic analysis of all copies of Hel1 Helitrons in C. suppressalis (a) and P. xuthus (b). Copies of different exemplars are indicated by distinct colors. The phylogenetic tree was constructed by the neighbor-joining method using MEGA 7.0 softwareBack to article page
