| Abstract: | Bt crops,one kinds of GM crops that express Cry1Ac or Cry1Ab protein have been commercialized worldwide. They are playing an important role in controlling insect pests. The issue of resistance evolution of the target pests is a key factor influencing the sustainable utilization of Bt crops. Through analyzing the biological characteristics of cadherin-like protein that is the main receptor of Bt Cry1A toxin, and its binding action with Bt toxin, this paper discusses the relation between gene mutation and Bt resistance, and summarizes the research progress achieved in DNA-based approaches for molecular detection of insect resistance. |
