Supplemental Table S4. Relative quantification of ICHO/ICOOH derivatives in rosette leaves of wild-type (Col-0) and mutant plants.

Rosette leaves of 16-18 plants per genotype (cultivated in two independent experiments) were individually pooled, extracted and the resulting extracts analysed by UPLC/ESI-QTOFMS. Metabolites were quantified using extracted ion chromatograms (for quantifier ions see Table 1). The resulting peak areas were normalized to fresh weight, log2-transformed and centred individually for each independent experiment to the median of the normalized and log2-transformed peak areas of wild-type (Supplemental Table S3). Significance analysis of differences between wild-type and mutant was performed by t-test (two-tailed, unequal variances, **P 10e-03, ***P 10e-04). Significant differences are marked in bold.
