BIOTEC awarded the US patent for inventing the method to increase the level of aromatic compound in rice

Research team at the Rice Gene Discovery Unit obtained a US patent for the method to increase aromatic fragrance in a rice plant. This invention is based on their discovery that the inhibition of Os2AP gene can result in the production of aromatic compound, 2-acetyl-1-pyrroline (2AP), the major potent flavor component of aromatic rice. The patent was applied in the US in January 2005 and granted on 13 November 2007. This patent has also been filed in Australia, China, the Philippines, Thailand, Japan, Vietnam, India, France and the European Patent Office (EPO).

Inventors of this patent consist of Dr. Apichart Vanavichit, Dr. Somvong Tragoonrung, Dr. Theerayut Toojinda, Dr. Samart Wanchana and Mr. Wintai Kamolsukyunyong.
