Dr Nicholas Casewell said: «These are the first snake genomes to be sequenced and fully annotated and our results in relation to the king
cobra provide a unique view of the origin and evolution of snake
venom, including revealing multiple genome - level adaptive responses to natural selection in this complex biological weapon system.
The diversification of these toxins correlates directly with their functional importance in prey capture, for example the most pathogenic king
cobra toxin family have undergone massive expansion, while, in contrast,
venom proteins with less important functions do not participate in the evolutionary arms race occurring between snakes and their prey.
Armed with the both the king
cobra and Burmese python genome the team was able to show that, despite previous hypotheses that
venom genes evolve «early» in the lineage leading to snakes,
venom gene families do not duplicate early, in fact the study shows that the rapid and extensive expansion of functionally important
venom toxin families is restricted to the venomous «advanced» snake lineage.
Researchers from LSTM, along with a team of international biologists who have recently sequenced the genome of the king
