Glutamate Triggers Long-Distance, Calcium-Based Plant Defense Signaling
September 21, 2018, via Science
Did you know that a leaf being eaten by a hungry insect quickly alerts its fellows to the impending danger? New research finds that the amino acid #glutamate is a wound signal released by injured leaves that sets off a #calcium wave propagating to distant tissues and eliciting defense responses.
Video below of glutamate concentration changes in response to damage was acquired using a Nikon SMZ25 stereomicroscope with NIS-Elements software.
