Figure 4From: An Expressed Sequence Tag collection from the male antennae of the Noctuid moth Spodoptera littoralis: a resource for olfactory and pheromone detection researchPhylogenetic tree of candidate odorant-binding proteins from S. littoralis , B. mori and other lepidopterans, including pheromone-binding protein (PBP) and general odorant-binding protein (GOBP) clades. The S. littoralis translated unigenes are shown in bold. Accession numbers are given in additional file 6. The tree was constructed with MEGA4, using the neighbour-joining method. Values indicated at the nodes are boostrap percentages based on 1000 replicates, and nodes with bootstrap values < 70% were collapsed. Bmor, Bombyx mori; Hvir, Heliothis virescens; Msex, Manduca sexta; Pxyl, Plutella xylostella; Sexi, Spodoptera exigua.Back to article page
