Can biologists arrangement the genomes of all the plants and the animals in the world, including this greater bird of paradise in Indonesia?
WASHINGTON, D.C.—When it comes to genome sequencing, visionaries like to bandy about big numbers: There’s the UK Biobank, for example, which promises to yze the genomes of 500,000 individuals, or Iceland’s accomplishment to abstraction the genomes of its absolute beastly population. Yesterday, at a affair actuality organized by the Smithsonian Initiative on Biodiversity Genomics and the Shenzhen, China–based sequencing assertive BGI, a baby accumulation of advisers upped the ante alike more, announcement their absorbed to, eventually, arrangement “all activity on Earth.”
Their plan, which does not yet accept allotment committed to it accurately but could bulk at atomic several billions of dollars, has been dubbed the Earth BioGenome Activity (EBP). Harris Lewin, an evolutionary genomicist at the University of California, Davis, who is allotment of the accumulation that came up with this eyes 2 years ago, says the EBP would booty a aboriginal footfall against its adventurous ambition by absorption on eukaryotes—the accumulation of bacilli that includes all plants, animals, and single-celled bacilli such as amoebas.
That strategy, and the EBP’s all-embracing concept, begin a acceptant admirers at BioGenomics2017, a acquisition this anniversary of conservationists, evolutionary biologists, systematists, and added biologists absorbed in applying genomics to their work. “This is a admirable idea,” says Oliver Ryder, a attention biologist at the San Diego Zoo Institute for Attention Analysis in California. “If we absolutely appetite to accept how activity evolved, genome ysis is activity to be allotment of that.”
Ryder and others drew parallels amid the EBP and the Beastly Genome Project, which began as an ambitious, controversial, and, at the time, technically absurd angle added than 30 years ago. That beforehand accomplishment eventually led not alone to the sequencing of the aboriginal beastly genome, but additionally to absolutely new DNA technologies that are at the centermost of abounding medical frontiers and the base for a $20 billion industry. “People accept abstruse from the beastly genome acquaintance that [sequencing] is a amazing beforehand in biology,” Lewin says.
Many capacity about the EBP are still actuality formed out. But as currently proposed, the aboriginal footfall would be to arrangement in abundant detail the DNA of a affiliate of anniversary eukaryotic ancestors (about 9000 in all) to actualize advertence genomes on par or bigger than the advertence beastly genome. Next would appear sequencing to a bottom bulk a breed from anniversary of the 150,000 to 200,000 genera. Finally, EBP participants would get asperous genomes of the 1.5 actor actual accepted eukaryotic species. These lower resolution genomes could be bigger as bare by comparing them with the ancestors references or by accomplishing added sequencing, says EBP co-organizer Gene Robinson, a behavioral genomics researcher and administrator of the Carl R. Woese Institute for Genomic Analysis at the University of Illinois in Urbana.
In this representation of the timberline of life, there are actual few completed genomes (red curve in close rim) amid called eukaryotes (green), but abounding added amid bacilli (blue) and archaea (purple). Amid the millions of eukaryotic species, there are alike almost few lower resolution genome sequences (blue, ablaze and aphotic gray).
The absolute eukaryotic accomplishment would acceptable bulk about the aforementioned as it did to arrangement that aboriginal beastly genome, appraisal Lewin, Robinson, and EBP co-organizer John Kress, an evolutionary biologist at the Smithsonian National Building of Natural History here. It took about $2.7 billion to apprehend and adjustment the 3 billion bases basic the beastly genome, about $4.8 billion in today’s dollars. With a commensurable bulk of support, the EBP’s eukaryotic assignment ability be done in a decade, its organizers suggest.
Such optimism arises from ever-decreasing DNA sequencing costs—one affair presenter from Complete Genomics, based in Mountain View, California, says his aggregation affairs to be able to almost arrangement accomplished eukaryotic genomes for about $100 aural a year—and improvements in sequencing technology that accomplish accessible college affection genomes, at reasonable prices. “It became credible to me that at a assertive point, it would be accessible to arrangement all activity on Earth,” Lewin says.
Although some may acquisition the multibillion-dollar amount tag adamantine to absolve for advisers not belief humans, the fundamentals of matter, or the mysteries of the universe, the EBP has a arch start, acknowledgment to the assignment of several ysis communities advancing their own aggressive sequencing projects. These accommodate the Genome 10K Project, which seeks to arrangement 10,000 bearcat genomes, one from anniversary genus; i5K, an accomplishment to yze 5000 arthropods; and B10K, which expects to accomplish genomes for all 10,500 bird species. The EBP would advice coordinate, compile, and conceivably armamentarium these efforts. “The [EBP] abstraction is a association of communities,” Lewin says.
There are additionally sequencing commitments from giants in the genomics field, such as China’s BGI, and the Wellcome Trust Sanger Institute in the United Kingdom. But at a planning affair this week, it became bright that cogent challenges anticipate the EBP, alike above funding. Although advisers from Brazil, China, and the United Kingdom said their nations are acquisitive to participate in some way, the 20 bodies in appearance emphasized the charge for the accomplishment to be added international, with developing countries, decidedly those with aerial biodiversity, allowance appearance the project’s final form. They proposed that the EBP could advice advance sequencing and added abstruse experts and capabilities in those regions. The Global Genome Biodiversity Network, which is accumulation lists and images of specimens at museums and added biorepositories about the world, could accumulation abundant of the DNA needed, but alike broader accord is important, says Thomas Gilbert, an evolutionary biologist at the Natural History Building of Denmark in Copenhagen.
The planning accumulation additionally fatigued the charge to advance standards to ensure high-quality genome sequences and to bottle associated advice for anniversary beastly sequenced, such as area it was calm and what it looked like. Getting DNA samples from the agrarian may ultimately be the better challenge—and the better cost, several bodies noted. Not all building specimens crop DNA preserved able-bodied abundant for high-quality genomes. Alike afresh calm and arctic bulb and beastly specimens are not consistently handled accurately for attention their DNA, says Guojie Zhang, an evolutionary biologist at BGI and the University of Copenhagen. And the abridgement of standards could attenuate the project’s ultimate utility, addendum Erich Jarvis, a neurobiologist at The Rockefeller University in New York City: “We could absorb money on an accomplishment for all breed on the planet, but we could accomplish a lot of crap.”
But Lewin is optimistic that won’t happen. After he categorical the EBP in the closing allocution at BioGenomics2017, he was amidst by advisers acquisitive to apperceive what they could do to help. “It’s acceptable to try to accompany calm the tribes,” says Jose Lopez, a biologist from Nova Southeastern University in Fort Lauderdale, Florida, whose “tribe” has army “GIGA,” a activity to arrangement 7000 abyssal invertebrates. “It’s a big endeavor. We charge lots of ability and lots of bodies who can contribute.”
