Table 1 Significantly changed metabolites in tea roots and leaves treated with MSX. U.d. indicated undetected metabolites. FDRs (q-value) were calculated in a hierarchical way according to the metabolites groups

From: Short-term inhibition of glutamine synthetase leads to reprogramming of amino acid and lipid metabolism in roots and leaves of tea plant (Camellia sinensis L.)
