Scientists hope the study of it and other giant genomes will shed light on species resilience. The New Caledonian fork fern (Tmesipteris oblanceolate) possesses the largest genome yet found. ORIANE HIDALGO ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The human genome is made up of 3 billion base pairs of DNA. But that’s nothing compared with the New Caledonian fork fern (Tmesipteris oblanceolate), a leafy, tendrilled plant native to several Pacific islands. Its genome contains an astonishing 160 billion base pairs, making it the largest genome ever discovered, researchers report today in iScience. The finding could help scientists understand how genomes grow so large, and how...
