INITIAL SIGNAL that stimulates jasminate synthesis, or the first sniff of trouble by the plant. "JA signaling can be induced by a range of abiotic stresses, including osmotic stress, wounding, drought, and exposure to “elicitors,” which include chitins, oligosaccharides, oligogalaturonides, and extracts from yeast." https://lnkd.in/efDsWiV View in LinkedIn

INTERPLANT WARNING SYSTEM. "Volatile organic compounds like jasmonate can warn nearby plants of a herbivorous predator that is causing damage to a neighbor, and the neighboring plants, even different species, smell the signal and within minutes start to make defensive molecules to ward off the herbivores." https://lnkd.in/eMFZkSs View in LinkedIn

VOLATILES. "When plants are damaged by insects, the amount of volatiles normally released by an intact plant increases significantly. These volatiles are qualitatively and/or quantitatively different from those emitted by undamaged or mechanically wounded plants." https://lnkd.in/eSPYN6W View in LinkedIn

VOLATILES. "C6-volatiles, aldehydes, and alcohols, all products of the HPL pathway, are synthesized rapidly upon wounding. These compounds also act as signaling molecules in the defense response." https://lnkd.in/eSPYN6W View in LinkedIn

TALKING TREES. "Plants may “eavesdrop” on volatile organic compounds (VOCs) released by herbivore-attacked neighbors to activate defenses before being attacked themselves. Transcriptome and signal cascade analyses of VOC-exposed plants suggest that plants eavesdrop to prime direct and indirect defenses and to hone competitive abilities." https://lnkd.in/etuE4VS View in LinkedIn

HOW PLANTS SMELL JASMONATE. The molecular machinery for salicylate acid (same as our aspirin) and jasmonate acid plant hormones from chemoreception to gene induction, with some key pathways shared by animal cells, especially through the stress modulator, NF-kappaB. https://lnkd.in/e4rD_UV View in LinkedIn

AIRBORNE VOLATILE JASMONATE triggers a defense reaction in plants. "Jasmonate, when applied to surfaces of tomato plants, induces the synthesis of a defensive proteinase proteins in the treated plant and in nearby plants as well." A widespread warning of plant damage to all neighbors. https://lnkd.in/ewBJUE3 View in LinkedIn

DEFENSE GENES. "Transcriptional regulation is a central process in plant immunity. The induction or repression of defense genes is orchestrated by signaling networks that are directed by plant hormones of which salicylic acid (SA) and jasmonic acid (JA) are the major players. The SA- and JA-responsive signaling pathways are interdependent and act in complex networks." https://lnkd.in/e4rD_UV View in LinkedIn

JASMONATE SIGNALS IN ARABIDOPSIS. "Mechanical tissue damage inflicted on rosette leave results in large (~10 fold) and rapid (within 5 min) increases in JA and JA-IIe levels in undamaged leaves of the rosette." https://lnkd.in/eKj_2Vj View in LinkedIn

ALTERNATIVE ANATOMY. In plants, damage signals include jasmonate, "peptide or cell wall-derived oligosaccharide fragments as well as wound-induced hydraulic and electrical systems," all without a nervous system. Quite remarkable. https://lnkd.in/eKj_2Vj View in LinkedIn
