The identity of the cell files necessary for the leaf-to-leaf transmission of wound signals plants has been debated for decades. In <i>Arabidopsis</i>, wounding initiates the glutamate receptor-like (GLR)-dependent propagation of membrane depolarizations that lead to defense gene activation. Using a vein extraction procedure we found pools of GLR-fusion proteins in endomembranes in phloem sieve elements and/or in xylem contact cells. Strikingly, only double mutants that eliminated GLRs from both ...[more]
