Tools & Techniques: Enhanced dsRNA Uptake in Insects, microRNA Detection at the Single-Cell Level, and More | GenomeWeb

Researchers from the Chinese Academy of Sciences have reported on a new discovery that could help enhance plant-mediated RNAi defense strategies against herbivorous insects.

While oral ingestion of plant-expressed dsRNA can trigger target gene suppression in insects, the insect peritrophic matrix, which prevents large molecules from passing into midgut cells, is a key barrier to the process, according to the investigators.
