UK start-up RNA AgriBio is looking to develop a potential RNA-based bio-insecticide. Former agronomist and founder Trevor Grigg has always been interested in science, so he returned to university to study crop protection, where he came across RNA interference (RNAi). During his PhD studies, he found various papers on how RNAi benefits humans, but less on farming, which got him thinking. Sereene Ghariani explains that RNAi isn’t genetic modification, but temporary gene silencing. By introducing foreign RNA, it gets internalised in cells. The cell takes the RNA sequence, which then breaks down messenger RNA molecules (mRNA) used to make a…
