Abstract:
The application of the RNA interference (RNAi) mechanism promotes the development of novel approaches toward sustainable crop protection. Compared with traditional double-stranded (ds)RNA delivery systems, nanoparticles offer great advantages in delivering dsRNA to improve RNAi efficiency, thus promoting the development and practice of RNAi-based pest management strategies. Here, we described a transdermal dsRNA delivery system with a nanosized star polycation, and presented a method to improve RNAi efficiency to increase the control effect against aphids. Insect gene functional analysis and pest management can be achieved by this method.

siRNA - Small Interfering RNAs
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...
RNA Interference
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...
