It's In The GenBank - 8

Nature


A very recent discussion of a very recent paper indicates that:

"A small, unassuming fern-like plant has something massive lurking within: the largest genome ever discovered, outstripping the human genome by more than 50 times1.

The plant (Tmesipteris oblanceolata) contains a whopping 160 billion base pairs, the units that make up a strand of DNA. That’s 11 billion more than the previous record holder, the flowering plant Paris japonica, and 30 billion more than the marbled lungfish (Protopterus aethiopicus), which has the largest animal genome. The findings were published today in iScience."

(Biggest genome ever found, emphasis added). Sounds remarkable, but a link to the nucleotides, the base pairs, i.e. the genome is a fundamental courtesy which was not provided.

A reader comment indicates that the genome of "Tmesipteris oblanceolata" (a.k.a. "Tmesipteris truncata") on science related databases does not have any genome of that size .

 Any links to the alleged 1.6 gigabyte genome would be helpful. 

BTW regular readers of Dredd Blog know that we go where 'they do not' (On The Origin Of A Genetic Constant 1, 2, 3, 4, 5, 6, 7, 8, 9, 10; On The Origin Of Another Genetic Constant, 2, 3, 4; It's In The GenBank, 2, 3, 4, 5, 6, 7; On The Origin of Genieology). 

And Dredd Blog always provides links to the official genomes discussed (ibid).

The previous post in this series is here.

  1. I can't find any such thing (of that size) in GenBank (Link).
