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

FLORAL SYMMETRY AND SPECIATION. "Changes in petal symmetry, petal reflection and cell shape can change the size of the visual floral display and colour saturation, creating differences in likely visitation by pollinators, thus effecting speciation via reproductive isolation among individuals with differing patterns of gene expression." http://onlinelibrary.wiley.com/doi/10.1111/nph.13198/full View in LinkedIn

GENE MODULE INTERACTIONS. "Finally, different modules of regulatory networks can interact differently across the tree of life. For example, in Pisum sativum conical cells occur only on petals with CYC2 expression and are lost when CYC2 expression is lost, implying a developmental constraint within this network that could be relaxed in other taxa." http://onlinelibrary.wiley.com/doi/10.1111/nph.13198/full View in LinkedIn

GENE LOCATION, TIMING, CONCENTRATION. "For instance, DipsCYC2A and DipsCYC2B both shift ventrally in Lonicera sempervirens, a species with a flower that is more radially symmetrical in form than the ‘typical’ Lonicera flower. Likewise, differential expression levels of MIXTA across Antirrhinum species correlate with changes in morphology that influence pollinator preferences." http://onlinelibrary.wiley.com/doi/10.1111/nph.13198/full View in LinkedIn

IRRITANTS. "AP is induced by non-damaging irritations; in particular, it is induced by electric currents, cooling, touch, some chemical agents, and changes in the light regime." (AP = action potential). http://link.springer.com/article/10.1007/s11120-016-0270-x View in LinkedIn

POLARIZATION. "As in the case of animal APs, ion channels mediate the generation of APs in plants. In addition, another type of long-distance signaling exists in plants: slow wave potentials (SWPs) (aka variation potentials, VPs). Both APs and SWPs (VPs) share the three-fold phase of depolarization–repolarization–hyperpolarization of animal APs." (VPs = variation potentials; APs = action potentials). http://link.springer.com/article/10.1007/s11229-016-1040-1 View in LinkedIn

PATHWAYS. "Electrical signals can propagate along the plasma membrane on short distances in plasmodesmata, and on long distances in a phloem." http://link.springer.com/chapter/10.1007/978-3-319-08807-5_6 View in LinkedIn
