Metabolite changes induced by PARP inhibition and detected by GC-MS.

For the GC-MS metabolite profiling samples, a total of ∼10 seedlings from 4 plates were harvested individually for both conditions (+/−3 MB) in each experiment, repeated in three individual experiments (n = 12). The plants were grown in parallel to those for the microarray expression analysis. The metabolite extraction and further processing was done at the “Plateforme Métabolisme-Métabolome (IFR87)” accordingly to (55). Metabolites that were significantly different (t-test, p
