Long-distance turgor pressure changes induce local activation of plant glutamate receptor-like channels
Following 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 calcium-permeable channel activated by glutamate binding) is important for systemic signaling; opening this channel […]
