Sequences are all published in NCBI. B. tabaci CSP1, CSP2 and CSP3 sequences are from JQ678989-ADG56568, KM078671- KM078679 and KM078694- KM078697, respectively. CSP sequences from Daphnia pulex (DpulCSP1 and DpulCSP2; ABH88167, ABH88166) are used as an outgroup. The triangles indicate the CSP proteins that have been functionally characterized. Black triangles: developmental genes, grey triangles: effector genes, white triangles: olfactory genes.
