“…6 However, as all studies were carried out on Japanese species, we were interested to know whether there is any chemical difference among species from other areas since it has been shown that different chemotypes do exist in some liverwort species. [7][8][9] Our results…”

“…The compounds we were able to tentatively identify were terpene-related. Apart from (+)-cyclosativene they are known to be produced by other mosses or liverworts [49][50][51][52][53] . Consequently, if the VOCs blend carried information about the genetic identity of S. flexuosum and the information was encoded by VOCs detected in our study, the key part of the cue could be (+)-cyclosativene, one of the unidentified compounds or a specific combination and/or concentration of the detected chemicals.…”

communication between vascular plants through volatile organic compounds (Vocs) impacts on ecosystem functioning. However, nothing is known about that between non-vascular plants. To investigate plant-plant Vocs interaction in bryophytes we exposed rare peatland moss Hamatocaulis vernicosus to Vocs of its common competitor Sphagnum flexuosum in an air-flow system of connected containers under artificial light, supplemented or unsupplemented by far-red (FR) light. When exposed to Vocs 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. This is the first evidence of plant-plant VOCs interaction in non-vascular plants, analogous to that in vascular plants. The findings open new possibilities for understanding the language and evolution of communication in land plants. Interactions are crucial for the survival of individuals in ecological communities 1. Consequently, animals and plants perceive a variety of cues by which they can ascertain what is in the proximity. Until the end of the twentieth century, however, the active sharing of information seemed solely the domain of animals. Plants were viewed as passive, stationary organisms, with only basic interactions with other organisms 2 , apart from pollinators. With the discovery of plant communication 3,4 , it became evident that plants use light 5 , touch 6-9 , vibrations 10 and chemicals 11-13 to communicate in an intricate web of multitrophic interactions that affect functioning of ecosystems. Volatile organic compounds (VOCs) are involved in communication in eukaryotic and prokaryotic organisms including animals and vascular plants 14 , bacteria 15 , brown algae 16 , and fungi 17. These secondary metabolites with low molecular weight and high vapour pressure at ambient temperature can move freely through the air. They are produced in cytosol (organelles or cytoplasm) and are possibly transported outside the cell through lipophilic carriers (in aqueous environments of cytosol and cell wall) and ABC transporters (through lipophilic plasma membrane 18,19). The production of VOCs by plants depends on genetic identity of the individual, life history and health, plant organ, photoperiod, light quality (e.g., red to far-red (R/FR) ratio), symbiotic organisms and other factors 1,20-23. Hence, each organism has a specific VOC blend including compounds unique for the given taxon 24 as well as chemicals with specific ecological meaning (e.g. 25). Species that can detect and decipher the encoded information can use VOCs in interactions, as a source of information. Plant-plant VOC interaction often takes the form of eavesdropping. Plants can estimate the strength of their neighbouring competitors and, accordingly, adjust their growth 26. Parasitic plants can use VOCs to locate their hosts 24. VOCs could even be use...

“…R. hemisphaerica and Mannia subpilosa produce marchantia quinone (26) [34,44]. Marchantin O (24), the monomethyl ether of marchantin C (10), and marchantin P (25) were obtained from R. hemisphaerica [44,46,47] and South American Marchantia chenopoda, respectively [37]. Their structures have been elucidated by analysis of the spectral data including difference NOE of the permethylated and the peracetylated derivatives.…”
