U.S. Utilizes Gene Technology to Increase Vitamin C Content in Grains
A team of researchers from the University of California, Riverside, USA, discovered that the use of GM technology to produce large amounts of DHAR enzymes in crops can significantly increase the levels of vitamin C contained in grains such as corn. This result is to improve certain daily routines. The nutritional health value of crops provides new tools. In crops, the recycling of vitamin C is mainly controlled by an enzyme called DHAR, which makes it possible to reuse vitamin C in crops. The lack of this enzyme results in the rapid loss of vitamin C in crops. Researchers have speculated that if more DHAR enzymes are produced in the crop, the vitamin C content may increase accordingly. The research team isolated the gene coding for DHAR enzyme from wheat and transcribed the gene in maize. As a result, the content of corn DHAR enzyme increased by up to 100 times. The study also found that the use of this method to cultivate transgenic corn leaves and sub-vitamin C also significantly increased.
