Investing transgenic crops with genetically modified toxins to fight pest resistance [Registered]

One of the most successful strategies in insect pest control is to endow crop plants with genes from the bacterium Bacillus thuringiensis, or Bt for short, which code for proteins that kill pests attempting to eat them. But insect pests are evolving resistance to Bt toxins, which threatens the continued success of this approach. In the recent issue of Nature Biotechnology published online on 9th October, a research team led by UA Professor Bruce Tabashnik reports the discovery that a small modification of the toxins’ structure overcomes the defenses of some major pests that are resistant to the natural, unmodified…
