  • I, Increase; D, decrease; N, no significant change in metabolite concentration. Names in brackets precede a match value for an unidentified compound. These names indicate best mass spectral similarity on a scale of 0 to 1,000 (1,000 is identical) to the indicated compound. *, Metabolite showed increase in other environmental stress conditions.
