The USDA’s Animal and Plant Health Inspection Service (APHIS) has granted deregulation status to Ishihara Sangyo Kaisha’s (ISK) genetically modified (GM) Phalaenopsis orchid ISK-311NR-4, as it has been deemed not to pose an increased plant pest risk relative to non-modified varieties. The orchid has been modified to express the flavonoid 3’ 5’-hydroxylase enzyme from Asiatic dayflower (Commelina communis) responsible for delphinidin-based anthocyanin production, resulting in blue-purple flowers.
