RNA Interference Method for Gene Function Analysis in the Japanese Rhinoceros Beetle .

In the Japanese rhinoceros beetle , various candidate genes required for a specific phenotype of interest are listed by next-generation sequencing analysis. Their functions were investigated using RNA interference (RNAi) method, the only gene function analysis tool for developed so far. The summarized procedure for the RNAi method used for is to synthesize double-stranded RNA (dsRNA), and inject it in larvae or pupae of . Although some dedicated materials or equipment are generally required to inject dsRNA in insects, the advantage of the protocol described here is that it is possible to inject dsRNA in with one syringe.
