Scientists Investigate Metabolic Changes in Genetic Modification of Resveratrol-enriched Rice

April 26, 2017

Resveratrol is a popular antioxidant present in grape skins, which might have helpful benefits for the heart. Thus, scientists developed resveratrol-enriched rice (RR) containing stilbene synthase gene to induce resveratrol production and phosphinothricin-N-acetyltransferase gene to confer herbicide resistance. Min Sung Kim of Incheon National University, South Korea, and a team of researchers evaluated if there are metabolic changes in rice enriched with resveratrol.

They planted the non-RR and RR plants for two seasons in three different areas in South Korea with different climatic conditions. Then they analyzed the principal components of the two rice varieties, which showed that chemical composition was affected more by growing season and location than genetic transformation. Furthermore, statistical analysis revealed that there were no significant differences in the biochemical structures of RR compared with the non-RR plants. The results also showed that herbicide treatment did not affect the chemical composition of RR.
