Plant Biology: Proteolytic Release of Damage Signals

Curr Biol. 2019 May 20;29(10):R378-R380. doi: 10.1016/j.cub.2019.04.014.


Plants protect their wounds against pathogen invasion by releasing damage signals that induce immune responses in neighboring cells. A new study shows that a conserved bioactive peptide is released from its cytoplasmic precursor upon wounding by a metacaspase that is activated by calcium influx into the injured cell.
