How do plant cells talk to each other using systemic signalling?
Plants transmit signals from cell-to-cell over long distances, sometimes traversing their entire length within minutes. These signals convey information about changes in the environment and/or the presence of pathogens.
As they pass from cell-to-cell, the signals turn “on” different defence and acclimation responses that make the plant more resilient to the stresses that triggered the signal. Cell-to-cell waves of reactive oxygen species, calcium, and electric signals mediate this process. But how they do so is a mystery.
