Metabolic changes in <i>A. thaliana</i> roots upon cultivation in hydroponic medium with alkaline pH as identified by GC-MS metabolite profiling.

Polar metabolites were extracted with methanol, derivatized and subjected to GC-MS analysis. Listed are compounds that showed a significant (P<0.05, Student’s t-test) difference (>1.5-fold) in three independent biological experiments. Entries are ordered according to their maximum relative abundance under alkaline conditions; n. i.: not unambiguously identified (no comparison with authentic standard), RI: retention index, R-Match: reverse match (only values above 800 are given).
