To utilize plant biomass efficiently, technologies for controlling useful phenotypes such as metabolic profiles in plants are desirable. As a sessile organism, plants are able to sense slight environmental changes and respond to them rapidly. Understanding and application of the plant responses lead to utilize their biomass efficiently. In this study, plant metabolites under artificial environments were analyzed comprehensively to reveal the plant response to light at the metabolite level. Metabolomics of Arabidopsis thaliana grown under red or far-red light revealed that the amounts of polyamine, which is an important metabolite to control their growth, are regulated by light. It was indicated that several useful secondary metabolites in crops were upregulated by a specific wavelength. Moreover, continuous light, never experienced under natural environment, significantly increased the metabolite.
