The bran from polished rice grains can be used to produce rice bran oil (RBO). High oleic (HO) RBO has been generated previously through RNAi down-regulation of OsFAD2-1. HO-RBO has higher oxidative stability and could be directly used in the food industry without hydrogenation, and is hence free of trans fatty acids. | RNAi-mediated down-regulation of the expression of OsFAD2-1 Effect on lipid accumulation and expression of lipid biosynthetic genes in the rice grain
