Tiny Fern from New Caledonia Holds Record for Largest Genome

Scientists have discovered that the New Caledonian fork fern, Tmesipteris oblanceolata, possesses the longest genome of any known living organism, with 416 chromosomes and 168 gigabase pairs of DNA. This genome is 50 times longer than a human's and surpasses the previous record holders in both plant and animal kingdoms. The discovery raises questions about the biological limits and implications of large genomes, highlighting the complexity and diversity of plant DNA.

Tiny Fern Holds Record for Largest Genome on Earth

The New Caledonian fern Tmesipteris oblanceolata has been recognized by Guinness World Records for having the largest genome of any organism, with 160 gigabase pairs of DNA, surpassing the previous record holder, Paris japonica. This discovery challenges previous assumptions about the biological limits of genome size and raises questions about the function and evolutionary significance of such large amounts of DNA.

Tiny Fern Holds Record for World's Largest Genome

The New Caledonian fork fern species Tmesipteris oblanceolata has set a new Guinness World Record for the largest genome of any living organism, with its DNA stretching about 328 feet, 50 times longer than human DNA. This fern's genome surpasses the previous record held by the Japanese plant Paris japonica. Researchers from the Royal Botanic Gardens, Kew, and the Institut Botànic de Barcelona discovered this after a 14-year study, highlighting the fern's ancient lineage predating dinosaurs.

Tiny Fern Sets World Record for Largest Genome

The New Caledonian fork fern, Tmesipteris oblanceolata, has been discovered to have the largest genome of any organism, with over 160 gigabase pairs of DNA, surpassing the previous record held by the Japanese flowering plant Paris japonica. Despite its massive genome, the fern's large cells make it less efficient at photosynthesis and slower growing compared to plants with smaller genomes. This discovery highlights the complexity and diversity of plant genomes and their ecological implications.

Tiny Fern Holds World Record for Largest Genome

The fork fern species Tmesipteris oblanceolata from New Caledonia has the world's largest genome, surpassing the previous record-holder by 7% and being over 50 times the size of the human genome. Despite its small size and unassuming appearance, this fern's genome size poses significant biological and ecological implications, including increased resource demands and slower cellular division. Scientists are still investigating why some organisms have such large genomes, as there is no direct correlation between genome size and organism complexity or physical size.

Tiny Fern Sets World Record for Largest Genome

The New Caledonian fern Tmesipteris oblanceolata has been awarded the Guinness World Record for the largest genome on Earth, with its DNA stretching taller than the Statue of Liberty. The fern's genome is 160 gigabase pairs, over 50 times more than humans. This discovery challenges previous assumptions about the biological limits of genome size and raises questions about the function and evolutionary significance of such large amounts of DNA.

Tiny Fern Holds World Record for Largest Genome

A rare fern from New Caledonia, Tmesipteris oblanceolate, has set a world record for having the largest genome of any living organism, with 160 billion base pairs of DNA. This genome, when unraveled, would stretch to about 100 meters, far surpassing the human genome's 2 meters. Scientists are intrigued by how this tiny plant functions with such an enormous amount of genetic material and hope to learn more about its evolutionary significance and potential impact on extinction risk.
