Title: Two glutamate- and pH-regulated Ca(2+) channels are required for systemic wound signaling in Arabidopsis.
Study confirms the involvement of GLR3.3 in amino acid response in A. thaliana root tip cells, supporting its role as a ligand-gated Ca2+ channel and presents the biochemical and structural characterization of its ligand-binding domain, showing that it works as an amino acid receptor with distinct specificity.
Title: The structural bases for agonist diversity in an Arabidopsis thaliana glutamate receptor-like channel.
GLR3.3 and GLR3.6 function as on switches for the propagation of wound-induced potentials beyond the wounded leaf, while GLR3.5 functions as an off switch that prevents the propagation of wound-induced electrical potentials to distal, non-neighbor leaves.
Title: New roles for the GLUTAMATE RECEPTOR-LIKE 3.3, 3.5, and 3.6 genes as on/off switches of wound-induced systemic electrical signals.
