Abstract: | "Diapause hormone (DH) and pheromone biosynthesis activating neuropeptide (PBAN), two important insect neuropeptides, regulate insect development and sex pheromone biosynthesis, respectively. DH-like immunoreactivity has been detected in the suboesophageal ganglion (SG) of pharate adult of Spodoptera exigua (Spe) by using an antiserum against Helicoverpa armigera DH. A full-length of Spe-DH-PBAN cDNA was obtained based on reverse transcription-PCR and rapid amplification of cDNA ends strategies. The open reading frame of this cDNA encodes a 197-amino acid precursor protein that contains DH, PBAN, and three other SG neuropeptides, all of which share a conservative C-terminal pentapeptide motif FXPR/KL (X = G, T or S). Northern blot analysis demonstrates the presence of an 800 bp transcript in the SG. The Spe-DH-PBAN mRNA is detectable at high levels at larval and adult stages, suggesting that Spe-DH-PBAN gene might be correlated with larval development and sex pheromone biosynthesis in moths" |
