Peptidoglycan recognition proteins (PGRPs) are important recognition receptors which play a critical role in signal identification and transmission in Toll or immune deficiency (IMD) pathways, particularly when pathogens evade and circumvent reactive oxygen species. Antimicrobial peptides (AMPs) synthesis can be activated by these signals to further eliminate pathogens. In this study, we cloned and characterized three different PGRP genes in Plutella xylostella strains, DBM1Ac-S, DBM1Ac-R and a field strain (DBM[sbnd]F). The results showed that...
