Researchers have filled two knowledge gaps: The vacuoles of plant cells can be excited and the TPC1 ion channel is involved in this process. The function of this channel, which is also found in humans, has been a mystery so far.

Many plant processes are not different from humans: Cells and tissues in grain plants, including maize also communicate through electrical signals. The shape and frequency of these signals tell a plant different things. ...
