Charles Darwin was deeply interested in carnivorous plants and was particularly fascinated by Venus flytrap(Dionaea muscipula)and sundew plants(Drosera spp.)of the Droseraceae family.He was intrigued by fast and slow trap movements in these plants and predicted the existence of a signal that transfers information from sensor to actuator within the trap organ.Based on his request,Sir John Burdon-Sanderson discovered electrical signals in Venus flytrap.Recent success in the transformation of non-model carnivorous plants with a Ca2+sensor has outlined a possible route for the evolution of sensory systems in the carnivorous family Droseraceae.
