THE GREEN FUSE. "Electrical signalling over long distances is an efficient way of achieving cell-to-cell communication in living organisms. In plants, the phloem can be considered as a ‘green cable’ that allows the transmission of action potentials (APs) induced by stimuli such as wounding and cold." (APs = action potentials). https://lnkd.in/dAJcV8P View in LinkedIn

NEUROTRANSMITTERS IN PLANTS. "Plant and animal cells and tissues share a number of ‘neural’ similarities. To name some of them, glutamate, dopamine, serotonin, and other neurotransmitters are found in plants, although their function still needs to be clarified (auxin can be identified as the plant-specific neurotransmitter for the purpose of signaling." http://link.springer.com/article/10.1007/s11229-016-1040-1 View in LinkedIn

HARDWIRED. "Analysis of cell type specificity in signal propagation has revealed the movement of systemic signals through specific cell types, suggesting that a rapid signaling network may be hardwired into the architecture of the plant." But not in a nervous system that animas use. http://www.annualreviews.org/doi/abs/10.1146/annurev-arplant-043015-112130 View in LinkedIn

ACETYLCHOLINE. "These findings demonstrate the ubiquitous expression of ACh and ACh-synthesizing activity among life forms without nervous systems, and support the notion that ACh has been expressed and may be active as a local mediator and modulator of physiological functions since the early beginning of life.” (ACh = acetylcholine). https://lnkd.in/dBN5S9C 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."

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
