A tiny fern has secured the Guinness World Record for having the largest genome of any living organism on Earth. When unravelled, the New Caledonian fork fern speciesgenome would reach about 328 feet, taller than the tower that holds the Big Ben bell and the Statue of Liberty. This is just about the DNA from one of the fern’s cells.species belong to a primordial group of plants that evolved long before the dinosaurs set foot on the Earth.
“To think this innocuous-looking fern boasts 50 times more DNA than humans is a humbling reminder that there’s still so much about the plant kingdom we don’t know, and that record holders aren’t always the showiest on the outside,” said Adam Millward of Guinness World Records.
“It is distinguished by its mainly epiphytic habit and restricted distribution in Oceania and several Pacific Islands.” Subsequently, they measured the amount of dye bound to the DNA within each nucleus, understanding that more dye indicated a larger genome. The analysis revealed that the species T. oblanceolata possessed a groundbreaking genome size of 160.45 Gbp, approximately 7% larger than that of P. japonica , as reported by
