venom and silk genes/proteins are identified. We find that venom genes evolved by sequential duplication, and that the toxic effect of venom is most likely activated by proteases present in the venom. The set of silk genes reveals a highly dynamic gene evolution, new types of silk genes and...
In summary, disulfide-rich spider-venom peptides are promising insecticide leads due to their invertebrate selectivity, stability, ease of production, and in many cases novel pharmacology. Moreover, it should be possible to use transgenes encoding these peptides as insect-resistant plant traits or ...
