As reported by the National Intitute of Agrobiological Sciences (NIAS), various genetically modified silks will be produced in Gunma Prefecture starting from around June 2016. The first products are fibroins into which fluorescent proteins are engineered, followed by silks which can be better stained through the incorporation of highly repetitive sequences, and by silks which are engineered to contain spider fibroin.
