Metabolomic analysis of methyl jasmonate treated Brassica rapa leaves by 2-dimensional NMR spectroscopy

The principal component analysis of the J-resolved NMR spectra showed discrimination between control plants and methyl jasmonate treated plants. Methyl jasmonate treatment resulted in a long term accumulation of indole glucosinolate, indole-3-acetic acid and malate conjugated hydroxycinnamates up to 14 days after treatment, which might be important compounds in plant defence responses.
