Exciting Plant Vacuoles
06/14/2019![The activity of the TPC1 ion channel in the vacuole membrane (yellow) is essential for the excitability of the vacuole.

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.
