Metabolites detected by LC-QTOF-MS (ESI negative mode) that were significantly different (student t-test, pmyb28myb29 double mutant and wild-type, and relative levels of some other relevant compounds.

aaccuracy of the mass measurement, as represented by the difference between the calculated and the measured accurate mass, expressed in ppm of calculated mass.bratio of the mean mass signal intensities of the compound in both genotypes.csignificance value in Students t-test.dAlkylglucosinolates not identified by comparison to standard but predicted from elemental composition.emasses not detected in the double mutant: ratios have been calculated relative to the noise level.
