Fig. 2: Structures of LCOs found in fungi.

a The generic structure of LCOs. b LCO structures determined by LC-MS/MS analysis of the butanol phase extract of culture media from fungi with various lifestyles. Red indicates the most abundant LCO structures. (§) indicates when untargeted mass spectrometry (MS) analysis was used. The other structures were detected in targeted MS mode (MRM) (see “Methods” for details of various possible MRM transitions). (*) indicates when more than one strain was analyzed. (n) is the number of residues of chitin oligomers, (R1) is the type of fatty acid, identified as saturated or unsaturated fatty acids. (R2–R6) are chemical substitutions: hydrogen (H), acetyl (Ac), carbamoyl (Cb), fucosyl (Fuc), fucosyl sulfate (FucS), methylfucosyl (MeFuc) and sulfate (S). (ϯ) indicates data published previously9.
