The Fraunhofer Society of Germany released a bulletin on December 8, saying that they have cultivated a transgenic potato containing only amylopectin, which is expected to save production costs for the relevant industries using amylopectin as raw material.
Common potatoes contain two kinds of starch - amylopectin and amylose. Amylopectin is widely used in food industry, paper industry and textile industry. According to the traditional method, to use amylopectin in industry, it is necessary to separate amylopectin from amylopectin in potatoes, which consumes both energy and capital. In Germany, the paper industry and adhesive industry alone need 500000 tons of high-purity amylopectin every year.
The researchers of Fraunhofer Society obtained 2748 transgenic seeds by applying the "directed induction of local genomic mutation technology", and found this new variety from them. This potato has the same appearance as ordinary potatoes, but only the gene responsible for producing amylopectin is active in its genetic genes, while the gene expression for producing amylose is inhibited.
