Genome-wide identification and comparative analysis of Cry toxin receptor families in 7 insect species with a focus on Spodoptera litura
文献摘要:
Cadherin,aminopeptidase N(APN)and alkaline phosphatase(ALP)have been characterized as Cry receptors.In this study,comparative genomic analysis of the 3 recep-tor families was performed in 7 insects.ALPs and APNs are divided into three and eight clades in phylogenetic trees,respectively.ALPs in clade 3 and APNs in clade 1 contain multiple paralogs within each species and most paralogs are located closely in chromo-somes.Drosophila melanogaster has expanded APNs in clade 5 and were lowly expressed in midgut.Cadherins are divided into 16 clades;they may diverge before holometabolous insect speciation except for BtR and Cad89D-like clades.Eight insects from different or-ders containing BtR orthologs are sensitive to Cry 1A or Cry3A,while five species without BtR are insensitive to both toxins.Most APNs in clade 1,several ALPs in clade 3,BtR and Cad89D-like genes were highly or moderately expressed in larval midgut of Spodoptera litura and the other six species,and several members in these clades have been identi-fied as Cry receptors.Expressions of putative S.litura Cry receptors in the midgut after exposing to Bt toxins were also analyzed.
