VENUS FLY TRAP sodium channel. “While K+ is the most abundant cation in the cytoplasm of plant cells, typically reaching about 100 mM, Na+ is highly toxic even at low-mM cytosolic concentrations. The key to salt tolerance is to sequester the Na+ taken up by the plant to the vacuoles or transfer it to older tissues.” https://lnkd.in/ddvAq4Y View in LinkedIn

CARNIVOROUS PLANT CONDUCTION. "They exhibit rapid trap movements and their traps contain numerous glands. Spontaneous generation of spikes with quite uniform shape, propagating across the recording area, has been observed for all types of sample. In the analysis of the electrical network, higher richer synchronous activity was observed relative to other plant species and organs previously described in the literature." https://lnkd.in/eVTKbBi View in LinkedIn

WIDESPREAD PHENOMENON. "The reader may probably have Mimosa pudica or Venus flytrap in mind as classic examples of electrically mediated leaf closure, but all plants depend in one form or another upon electrical signaling." http://link.springer.com/article/10.1007/s11229-016-1040-1 View in LinkedIn

ALTERNATIVE MECHANISM. "Rapid closure is brought about by a combination of elastic properties and biochemical/biophysical changes in the motor cells. However, unlike animal neuronal action potentials in which Na+/Ca2+ ions carry the depolarizing phase of the action potential, the rapid depolarization component of the Venus flytrap action potential is most likely brought about by the opening of rapid (R-type) anion channels since plants lack the voltage-sensitive cation channels that characterise animal excitability." http://www.sciencedirect.com/science/article/pii/S096098221300849X View in LinkedIn

PLANT CONDUCTION. "The immediate and rapid snapping shut of the trap is a perfect demonstration of a sensory-motor system that involves neither nerves nor muscles. It has been known for some time that the mechanism underlying the closure of the trap involves the generation of very fast electrical depolarizations in the form of action potentials by the cells of the trigger hairs which lead to the rapid closure of the trap."
