| Outline of Final Research Achievements |
Chlorogenic acid (CGA) is one of the polyphenol compounds and its health functions are expected because of the high antioxidant capacity. In this study, as we have focused on the CGA accumulation effect in lettuce plants grown under long day condition, and we tried to confirm the environmental factors to induce the higher CGA accumulation in lettuce plants for developing a new cultivation technologies to produce high CGA content lettuce in plant factory system. In the growth cabinet, the combination of continuous lighting, blue light irradiation, high CO2 concentration and root volume restriction treatment could induce the high CGA content, approximately up to 200 mg 100 gFW-1, in young lettuce plants. From results of metabolome analysis, it was shwon that in the case of a young lettuce plants, the CGA accumulation conditions could give a strong stimulus for the shikimic acid pathway on the synthesis and accumulation of CGA.
