Abstract
RNA interference (RNAi) has been recently exploited to determine gene function by degrading specific mRNAs in several eukaryotic organisms. We constructed a double stranded RNA (dsRNA) from a previously cloned Haemaphysalis longicornis serine proteinase (HlSP) gene to test the importance of the function of the HlSP gene product during blood-feeding. Growth of unfed ticks treated with HlSP dsRNA was significantly inhibited compared to that of PBS-treated ticks. This inhibition was supported by the level of HlSP mRNA. HlSP may play a crucial role for blood-feeding in these ticks. This is the first report on gene silencing of a functional serine proteinase in hard ticks.Entities:
