Antimicrobial peptide gene BdPho responds to peptidoglycan infection and mating stimulation in oriental fruit fly, Bactrocera dorsalis (Hendel).

ABSTRACT: Phormicins belong to defensin family, which are important antimicrobial peptides (AMPs) in insects. These AMPs are inducible upon challenging by immune triggers. In the present study, we identified the cDNA of a phormicin gene (BdPho) in the oriental fruit fly, Bactrocera dorsalis (Hendel), a ruinous agricultural pest causing great economic losses to fruits and vegetables. The cDNA of BdPho contains a 282 bp open reading frame encoding 93 amino acid residues, and the predicted molecular weight and isoelectric point of BdPho peptide were 9.83 kDa and 7.54, respectively. Quantitative real-time PCR analyses showed that the transcription level of BdPho was the highest in adult during different developmental stages and was the highest in abdomen among adult tagmata. Moreover, BdPho was highly e
