Recent highlights in Molecular Biology and Evolution Defensins, as their name implies, are small proteins found in plants and animals that help ward off viral, bacterial or fungal pests. One fascinating question of invertebrate evolution is how these proteins evolved into venoms to attack their prey. Based on structural similarity, it was proposed that scorpion toxins and antimicrobial invertebrate defensins could have a common ancestor. To address how a nontoxic protein develops into a...

Some of the toxins in this cocktail damage only insects, which is why a Tel Aviv University researcher is harnessing them to create a safe and ecologically sound pesticide. Prof. Michael Gurevitz of Tel Aviv University's Department of Plant Sciences has...
