摘要

The pine sawyer beetle,Monochamus alternatus,is regarded as a notorious forest pest in Asia,vectoring an invasive pathogenic nematode,Bursaphelenchus xylophilus,which is known to cause pine wilt disease.However,little sequence information is available for this vector beetle.This hampered the research on its immune system.Based on the transcriptome ofM.alternatus,we have identified and characterized 194 immunity-related genes in M.alternatus,and compared them with homologues molecules from other species known to exhibit immune responses against invading microbes.The lower number of putative immunity-related genes in M.alternatus were attributed to fewer C-type lectin,serine protease (SP) and anti-microbial peptide (AMP) genes.Phylogenetic analysis revealed that M.alternatus had a unique recognition gene,galectin3,orthologues of which were not identified in Tribolium castaneum,Drosophila melanogastor,Anopheles gambiae and Apis mellifera.This suggested a lineage-specific gene evolution for coleopteran insects.Our study provides the comprehensive sequence resources of the immunity-related genes ofM.alternatus,presenting valuable information for better understanding of the molecular mechanism of innate immunity processes in M.alternatus against B.xylophilus.
