Porphyra is a genus of coldwater seaweeds that grow in cold, shallow seawater. More specifically, it belongs to red algae phylum of laver species (from which comes laverbread), comprising approximately 70 species.[2] It grows in the intertidal zone, typically between the upper intertidal zone and the splash zone in cold waters of temperate oceans. In East Asia, it is used to produce the sea vegetable products nori (in Japan) and gim (in Korea). There are considered to be 60–70 species of Porphyra worldwide[3] and seven around Britain and Ireland, where it has been traditionally used to produce edible sea vegetables on the Irish Sea coast.[4] The species Porphyra purpurea has one of the largest plastid genomes known, with 251 genes.[5]
