ULTRASOUND REFLECTOR. "A carnivorous plant features an ultrasound reflector attractive for mutualistic bats. This reflector enables the bats to easily find and identify the plant’s pitchers. The bats fertilize these Paleotropical plants with feces in exchange for roosts. Such reflectors were convergently acquired in Neotropical bat-pollinated plants." https://lnkd.in/ecwdnWm 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."

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

PLANT ELECTRICITY. "Electrical signals are believed to mediate intracellular, intercellular and interorgan communication within all plant systematic levels, from algae and bryophytes to vascular plants." https://lnkd.in/eVTKbBi View in LinkedIn

PLANT ACTION POTENTIALS. "The majority of cells in different plant species are electrically active and excitable, being able to release and propagate action potentials (APs). These electrical signals even influence principal physiological processes such as photosynthesis and respiration." https://lnkd.in/eVTKbBi View in LinkedIn

"ELECTRICAL PHENOMENA in single plant cells are to a great extent very similar to those occurring in animal cells. All plant cells actively maintain an electrical cell membrane potential difference of −30 to −250 mV between the vacuole or cytosol and the external medium." https://lnkd.in/eVTKbBi View in LinkedIn

UNINTENDED CONSEQUENCES. "Another explanation is that high nucleotide substitution rates are linked to reactive oxygen species (ROS) generated from the increased respiratory rates needed for the oxidative phosphorylation of ADP to ATP upon movement of trapping devices in carnivorous plants." https://lnkd.in/e4xhW7h View in LinkedIn

MASSIVE GENE PROLIFERATION. "The estimated haploid genome size range from 63 Mbp to >3 Gbp indicate that carnivorous plants have undergone dramatic genome evolution. An explanation for such massive proliferation of genome rearrangements, as observed in plastid genomes of Lentibulariaceae members, may be associated with increasingly relaxed functional constraints due to the heterotrophic lifestyle of carnivorous plants." https://lnkd.in/e4xhW7h View in LinkedIn

CARNIVOROUS PLANT GENOMES. "Large variations in ploidy levels and chromosome sizes have been reported within the carnivorous Droseraceae. The genome contents of carnivorous plants seem to be extremely variable, and the larger genomes tend to have many repetitive sequences and transposable elements."
