2021-04-22 21:38 Plant metabolomics is more and more used for understanding physiological processes like the cellular responses to various stimuli. For example, in response to sulfur deficiency, the metabolites will be readjusted. It is found that there is a strict relationship between sulfur assimilation, nitrogen, lipid, and purine metabolism and enhanced photorespiration. What's more, metabolomics has been used for studying cold stress response. Metabolic engineering of biochemical pathways for pharmaceuticals production, gene function discovery are other applications of plant metabolomics.
