Glutamate receptors shape plant systemic wound signaling and anti-herbivore defense
Plant Science Research WeeklySystemic immunity, where local plant interactions with microbes or insects trigger enhanced resistance in distant organs, has parallels to the nervous system in animals. In plants, GLUTAMATE RECEPTOR-LIKE (GLR) genes have a pivotal role in long-distance wound signal transmission and the initiation of…
Long-distance turgor pressure changes induce local activation of plant glutamate receptor-like channels
Plant Science Research WeeklyFollowing wounding or herbivory, plants can rapidly transmit signals systemically (over long distances). These systemic signals are thought to enhance plant defenses by preparing distant tissues for imminent attack. Genetic studies have shown that the glutamate receptor-like calcium channel GLR3.3 (a…
