Classification and phylogenetic tree of sequences identified in Macrosiphini tribe. a Classification of the 115 sequences obtained from Acyrthosiphon pisum, 45 from Diuraphis noxia and 23 from Myzus persicae. These 183 sequences, along with 146 elements belonging to the Tc1/mariner superfamily were classified using the UPGM-VM method [19]. References and positions of all these sequences are given in Additional file 3 according to the reading sense indicated by the arrow in the circular tree. Sequences found in A. pisum, D. noxia and M. persicae are given in colour, in green, brown and grey, respectively. Complete sequences are marked by a full black circle and MITEs by an empty circle. b The phylogeny based on amino-acid sequences of the 15 lineages. After a search of the best evolutionary scenario (ProTest 2.4), this tree was generated in MEGA6 with the Maximum likelihood (ML) method, using the WAG + F + I + G model. Only bootstrapping values (1000 replications) higher than 60% are written on the branch. Families and subfamilies are indicated in the right-hand part of the tree. The colored rectangles correspond to the different tribes as in A. Green squares, grey lozenges and brown triangles refer to the aphid species A. pisum, D. noxia and M. persicae, respectively. The designation of unpublished sequences extracted from other species than those of the three aphids includes a point (i.e. Vemar. from Vollenhovia emeryi). Sequences name: Apismar: elements from Acyrthosiphon pisum, Dnomar: elements from Diuraphis noxia and Mpmar: elements from Myzus persicae
