March 28, 2008

The research team at Kasetsart University in Thailand that elucidated the compound responsible for aroma in rice and the method to increase the aromatic fragrance has obtained a US patent. 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).

Rice Gene Discovery Unit is a collaborative research unit between BIOTEC and Kasetsart Univerity.
