Deciphering the role of a mechano-sensitive channel in long distance plant wound signaling
Insect herbivory and mechanical wounding of plants have long known to elicit long distance electrical signals, and these signals have been linked to the activation of defense mechanisms in distal tissues naive to the wounding stimuli. Recently, members in the GLUTAMATE RECEPTOR-LIKE (GLR) family were shown to be necessary for both the electrical signals and the concurrent jasmonic acid defense responses in unwounded leaves in Arabidopsis upon mechanical wounding. I will present new work that adds a mehcano-sensitive channel as a key player in the wound signaling process.
