Researchers have identified it Tmesipteris oblanceolataa fern from New Caledonia, which has the largest recorded genome, surpassing the previous record holder Paris japonica. This discovery, described in the iScience magazine, reveals that this fern contains more than 50 times more DNA than humans and highlights the significant implications that larger genomes have for plant biology … Read more
Last year, Jaume Pellicer led a team of fellow scientists to a forest on Grande Terre, an island east of Australia. They were looking for a fern called Tmesipteris oblanceolata. Being only a few centimeters in size, it was not easy to find on the forest floor. “It’s not noticeable,” says Dr. Pellicer, who works … Read more
A small, seemingly inconspicuous fern that grows alone on a remote island in the Pacific Ocean was crowned the Guinness World Record holder on Friday for having the largest genome of any organism on Earth. The New Caledonian fern, Tmesipteris oblanceolatahas more than 50 times more DNA in the cell nucleus than humans. If the … Read more
Researchers have mapped the entire X and Y chromosomes of several great ape species, revealing significant evolutionary variations, especially in the rapidly evolving Y chromosome. This study, which highlights both stable and dynamic genomic regions, provides new insights into primate and human evolution, as well as the conservation of these endangered species.
