Metabolic response of Gracilaria vermiculophylla analysed by GC/MS.

A: metabolites significantly up-regulated followed by mechanical simulation of herbivory. B: metabolites significantly up-regulated followed by exposure to extracts from previously mechanically wounded algae. Metabolic responses are presented as peak areas normalised to corresponding controls (means±SE, n = 8 (A), or 7 (B)). Suggested structures are from comparisons of MS spectral data with spectra in the NIST library. Metabolites with confirmed structure by comparisons to known standards in bold.1The most intense ion is given (the ion m/z = 73 in not considered in this listing).2Library suggestion are only included if the match and reverse match were more than 790.
