An entomopathogenic bacterium, Xenorhabdus nematophila, is known to depress hemocyte nodule formation of target insects by inhibiting eicosanoid biosynthesis. This study analyzed the inhibitory effect of X. nematophila on the humoral immunity of the target insects and tested its association with the
A 371 bp full-length cDNA (GenBank Accession No. DQ232774) was obtained from housefly Musca domestica by using degenerate primers and subsequent amplification by 5'- and 3'-RACE. The cecropin gene, Mdcec and Mdcec/6His, was cloned into expression pPICZalpha-A vector and was expressed in the
Cecropins belong to the antibacterial peptides family and are induced after injection of bacteria or their cell-wall components. By silkworm cDNA microarray analysis, a novel type of Cecropin family gene was identified as a cDNA up-regulated in early embryo, 1 day after oviposition. The cDNA
