RNAi crop approved

摘要

FOR the first time, a crop that produces an RNAi-based pesticide has got the green light. The US Environmental Protection Agency has approved a genetically modified corn known as SmartStax Pro. In addition to producing two Bt toxins to kill any western corn rootworm larvae that try to eat it, the plant produces a piece of RNA that shuts down a specific gene inside the larvae, killing them.
