The ABC- B full transporters in Lepidoptera. a The evolution within the ABC-B full transporter family was analyzed with CAFE. Each tip of the tree represents a species mostly of Lepidoptera. The numbers present next to each tip correspond to the number of predicted ABC- B full transporters, while the node numbers correspond to CAFE predictions for ABC-B full transporter family sizes. Color coding of the nodes signifies bootstrap support with > 90 % = Green; 70–90 % =Yellow; <70 % = Red; NA = Gray. b A phylogeny of a subset of ABC- B full transporters was made in order to understand the relationship of these transporters among Lepidoptera and other groups. The majority of P-glycoproteins from Lepidoptera do not show species specific expansions suggesting that an expansion occurred common to all Lepidoptera. In contrast, the clustering of the N. viridula P-glycoproteins suggest a distinct origin for this expansion
