We provide the first evidence of interspecific plant–plant interaction in bryophytes mediated by Volatile Organic Compounds (VOC). We used a model pair of peatland mosses, Sphagnum flexuosum and Hamatocaulis vernicosus. When exposed to VOC of S. flexuosum, shoots of H. vernicosus elongated and emitted six times higher amounts of a compound chemically related to β-cyclocitral, which is employed in stress signalling and allelopathy in vascular plants. The VOCs emission was affected similarly by FR light addition, possibly simulating competition stress. Since the interaction closely resembles that in vascular plants, one might speculate it evolved in a common ancestor of land plants.
