LARGELY UNKNOWN. "The specific sensory mechanisms available in plants for detecting sound are still unclear. No scientific studies that I am aware of have been conducted on the potential acoustic communicative abilities of plants." http://beheco.oxfordjournals.org/content/24/4/789.full View in LinkedIn

MOLECULAR IMPACT OF SOUND. "Sound waves elicit changes at the molecular and physiological level, including the levels of polyamines and important phytohormones (e.g., indole acetic acid and abscisic acid, the regulation of antioxidant enzymes, the uptake of oxygen, the synthesis of RNA and soluble proteins, and perhaps most importantly, gene expression." http://beheco.oxfordjournals.org/content/24/4/789.full View in LinkedIn

RESPONSE TO SOUND. "Whichever explanation for the origin of acoustic emissions from plants is correct, the fact remains that plants emit sounds and they “hear” them too. Decades of scientific research indicate that plants do respond to sound waves of different frequencies by modifying germination and growth rates." https://lnkd.in/dd33rp7 View in LinkedIn

BEYOND CAVITATION. "Although it remains undisputed that cavitation can induce acoustic emissions, the acoustic signals emitted by plants are so numerous that it always seemed extremely unlikely that each acoustic event was attributable to cavitation alone." http://beheco.oxfordjournals.org/content/24/4/789.full View in LinkedIn

MECHANICAL BOOMING. "Acoustic emissions are generally interpreted as the result of the abrupt release of tension in the water-transport system of plants following cavitation as water is pulled by transpiration from the roots through the xylem to the leaves." http://beheco.oxfordjournals.org/content/24/4/789.full View in LinkedIn

CLASSES OF SIGNALS. "Not only hydraulic and chemical signals, but also electrical signals act on the perception of environmental stimuli and trigger biochemical and physiological changes such as elongation, growth, water transport, displacement of substances in phloem, reduction of turgor pressure, variation of photosynthesis, respiration, and gene expression, mediating the relation between the plant and its external environment." http://link.springer.com/article/10.1007/s11738-015-1950-4 View in LinkedIn

MECHANICAL STIMULI. “The ability to sense and respond to a wide variety of mechanical stimuli—gravity, touch, osmotic pressure, or the resistance of the cell wall—is a critical feature of every plant cell, whether or not it is specialized for mechanotransduction.” https://lnkd.in/dazh-wp View in LinkedIn
