Insect-resistant transgenic plants

摘要

The technology of insect-resistant transgenic plants is expanding very rapidly, with considerable research activity in both the private and public sectors. The only commercialized insect-resistant transgenic plants to data express genes derived from the bacterium Bacillus thuringiensis, but a wide range of genes form higherplants have also been transferred into crop cultivars, especially genes encoding inhibitors of digestive enzymes and lectins. The use of resistance genes form other microorganisms and animals has so far been limited.
