Volatile communication in plants relies on a KAI2-mediated signalling pathway

Cool paper from my field. In every plant species there’s a hormone receptor sitting there but we don’t know what the hormone is yet! Finding the ligand has become a bit of a holy grail for many researchers. This study finds an endogenous ligand for a divergent homologue of this receptor, not of much consequence to most plant species but still enough to have people turning heads.
