نبذة مختصرة : ( A ) Molecular phylogenetic analysis of nAChRs in B . tabaci and other insects. Species codes are Agam = Anopheles gambiae , Amel = Apis mellifera , Bm = Bombyx mori , BT = Bemisia tabaci , Cs = Chilo suppressalis , D = Drosophila melanogaster , Nvit = Nasonia vitripennis , Tcas = Tribolium castaneum . The amino acid sequences of insect nAChRs were aligned using Clustal W. A phylogenetic tree was generated in MEGA 7 using the neighbor-joining method with 1000 bootstrap replicates. ( B ) Gene structures and chromosomal locations of B . tabaci nAChRs. ( C ) Sequences of alternative exons in BTα4 and BTα6 . Amino acids that changed are highlighted. ( D ) A to I editing site in BTα6 . The N-glycosylation site is boxed.
