Untargeted metabolomic profiling of Sphagnum fallax reveals novel antimicrobial metabolites.

摘要: Sphagnum mosses dominate peatlands by employing harsh ecosystem tactics to prevent vascular plant growth and microbial degradation of these large carbon stores. Knowledge about Sphagnum-produced metabolites, their structure function, is important better understand the mechanisms, underlying this sequestration phenomenon in face climate variability. It currently unclear which compounds are responsible for inhibition organic matter decomposition mechanisms occurs. Metabolite profiling fallax was performed using two types mass spectrometry (MS) systems 1H nuclear magnetic resonance spectroscopy (1H NMR). Lipidome LC-MS/MS. A total 655 including one hundred fifty-two lipids, were detected NMR LC-MS/MS-329 novel metabolites (31 unknown lipids). Sphagum metabolite profile composed mainly acid-like flavonoid glycoside compounds, that could be acting as potent antimicrobial allowing control its environment. composition comparison against previously known confirmed trend, with seventeen discovered present fallax, majority acids glycosides. Biological activity needs further tested confirm qualities. Three fungal identified providing insights into colonization may benefit Sphagnum. Characterizing provided a baseline acts on environment, relation peatlands, provide key biomarkers predict peatland C store changes (sequestration, emissions) shifts.
