PLANT OLFACTION. "The tendrils of plants are especially sensitive to airborne volatile organic compounds." Parasites such as Dodder make use of this in locating and locking onto prey. https://lnkd.in/eq7X3tN View in LinkedIn

"ELECTROCHEMICAL EXCITATION is caused by ionic fluxes through the cell plasma membrane, creating an electric charge modification in the membrane itself, as well as a differential charge on either side. Plant plasma membranes always maintain a potential, the cell interior being more negative than the exterior, arising mainly from the activity of electrogenic pumps." https://lnkd.in/e6_VTMg View in LinkedIn

PLANT ACTION POTENTIALS. "The existence of electrophysiological mechanisms for information perception, transmission and processing between different plant organs and tissues, allowing the expression of fast and accurate physiological reactions to specific biotic or abiotic stimuli, is expressed by means of real-time detectable action (APs) and variation (VPs) potentials." https://lnkd.in/e6_VTMg View in LinkedIn

CHIRAL MOLECULES are responsible for the characteristic smells are also part of the synthetic chemistry of terpen-4-ol, linalool, tea tree oil, lavender oil, lemon oil and many other essential oils. https://lnkd.in/ecJcdBW View in LinkedIn

PLANT ELECTROPHYSIOLOGY. "While plants have no neurons these cells are capable of making an electrical action potential in response to environmental stimuli, just like mammals." Once an urban myth, now supported by science. https://lnkd.in/ejqmafX View in LinkedIn

LANGUAGE OF SNIFFERS. Rose oxide isomers differ in smell: "1. Floral-green, clean, rose, green, strong; 2. Floral-green, green, herbal, minty, fruity; 3. Herbal-green-floral, smell of hay, green, earthy; 4. Herbal-green-floral, fruity, herbal rose, citrus (bitter rind)." https://lnkd.in/eMTZmZF View in LinkedIn

NERVOUS SYSTEM PROTEINS. "Plants produce several proteins found in the animal neuron nervous system such as acetylcholine esterase, glutamate receptors, GABA receptors, and endocannabinoid signaling components. They also use ATO, NO, and ROS like animals for signalling." https://lnkd.in/eBdU9He) View in LinkedIn

AMBERGRIS (ambra) is the musty scent derived from the digestive tract of the sperm whale, and only the (-) form is prized. https://lnkd.in/e9NBUvg View in LinkedIn

DIFFERENT SYSTEM. Plants "don't have noses or a nervous system, but they still have an olfactory sense, and they can differentiate." https://lnkd.in/ebihGuY View in LinkedIn

JASMINE SMELLS are from methyl dihydrojasmonate (hedione), but only in one chiral form has the intense floral odor. This becomes important when we return to plant olfaction next weekend. https://lnkd.in/e9NBUvg View in LinkedIn
