Registration is now open for the 2019 GP-WRITE & 8TH ANNUAL SC2.0 MEETING
Hosted by the Institute for Systems Genetics at NYU Langone Health

November 11-14

Synthetic genomics is an emerging field driven by the rapidly decreasing cost of gene synthesis, scalable DNA assembly technologies, and the ever-increasing amount of genome sequence data. To date, convergence of these technologies has enabled total genome synthesis projects targeting viral, bacterial and yeast genomes.

This meeting will bring together global leaders in the field of genome writing, focusing on achievements to date, and more importantly, what’s coming up next.  Major topics will include whole genome engineering efforts via bottom-up design and total synthesis, as well as top down, massively parallelized genome editing by designer nucleases.

The Genome Project-write (GP-write) is an open, international research project led by a multi-disciplinary group of scientific leaders who will oversee a reduction in the costs of engineering and testing large genomes in cell lines more than 1,000-fold within ten years.

The Synthetic Yeast Genome Project, Sc2.0, is an international and collaborative effort aiming to design and build the 16 synthetic chromosomes of the world’s first designer eukaryotic cell.

7th international yeast 2.0 and synthetic genomes conference

Synthetic Biology is widely believed to have the potential to make the most profound impact on the way we solve the many grand challenges facing humanity over the next 50 years. Conferences, such as this one, which bring together individuals involved in this field from around the world, are crucial to supercharge the intellectual horsepower required to ‘join the dots’.

The 7th Yeast 2.0 and Synthetic Genomes conference, to be held in the spectacular city of Sydney in November 2018, will provide delegates the opportunity to hear speakers who have made or have the potential to make significant impacts in the synthetic biology world.  Synthetic genomics takes science and technology into a whole new dimension, and will provide the impetus to propel the bioeconomy, to meet the complex needs of a rapidly greying global population.  The conference program will highlight work currently being undertaken in the most crucial areas, and delegates will have ample opportunity to network with colleagues, to exchange ideas and to forge new collaborations.

This conference also acts as a pivotal moment for the international Yeast 2.0 project.  This history-in-the-making project will open-up the possibility of producing energy-rich molecules for renewable biofuels and sustainable industrial chemicals; compounds for the bio-remediation of polluted environments; novel antibiotics, vaccines and personalised medicines; and adequate nutritious and safe food supplies to meet the future demands of a global population of 10 billion people of which two-thirds will be over the age of 60 by 2050.

We invite you to join with us for this very special conference (registration), and look forward to welcoming you to Sydney in November 2018.

6th Annual Sc2.0 Meeting, Singapore

The Synthetic Yeast Genome Project (Sc2.0) is the world’s first synthetic eukaryotic genome project that aims to create a novel, rationalized version of the genome of the yeast species Saccharomyces cerevisiae. In a truly global collaborative effort, research teams across the world have embarked on the challenging but exciting task of building 16 designer synthetic chromosomes encompassing ~ 12 million base pairs of DNA.

From 13-16 June 2017, international synthetic biology communities will convene in Singapore for SB7.0. The Seventh International Meeting for Synthetic Biology where several esteemed members of the Sc2.0 consortium will be speaking. The conference presents an opportune time for members of the Sc2.0 consortium to gather once again to discuss the progress on our concerted efforts on the Synthetic Yeast Genome Project and how we can lend support to one another to forge ahead towards finishing the world’s first synthetic eukaryotic genome together.

Location: National University of Singapore, Kent Ridge Guild House, 9 Kent Ridge Drive, 119241, Singapore

Sc2.0 project hits new milestone: 5 additional chromosomes completed!

The global Sc2.0 team has built five new synthetic yeast chromosomes, meaning that 30 percent of S.cerevisiae’s genetic material has now been swapped out for engineered replacements. This is one of several findings of a package of seven papers published March 10 as the cover story for Science.

An international team of more than 200 authors produced the latest work from the Synthetic Yeast Project (Sc2.0). By the end of this year, this international consortium hopes to have designed and built synthetic versions all 16 chromosomes – the structures that contain DNA – for S. cerevisiae.

Like computer programmers, scientists add swaths of synthetic DNA to – or remove stretches from – human, plant, bacterial or yeast chromosomes in hopes of averting disease, manufacturing medicines, or making food more nutritious. Yeast has long served as an important research model because their cells share many features with human cells, but are simpler and easier to study.

“This work sets the stage for completion of designer, synthetic genomes to address unmet needs in medicine and industry,” says Jef Boeke, the Sc2.0 project director.  “Beyond any one application, the papers confirm that newly created systems and software can answer basic questions about the nature of genetic machinery by reprogramming chromosomes in living cells.”

In March 2014, Sc2.0 successfully assembled the first synthetic yeast chromosome (synthetic chromosome 3 or synIII) comprising 272,871 base pairs, the chemical units that make up the DNA code. The new round of papers consists of an overview and five papers describing the first assembly of synthetic yeast chromosomes synII, synV, synVI, synX, and synXII. A seventh paper provides a first look at the 3D structures of synthetic chromosomes in the cell nucleus which mimic their native counterparts with remarkable fidelity.

Many technologies developed in Sc2.0 serve as the foundation for GP–write, a related initiative aiming to synthesize complete sets of human and plant chromosomes (genomes) in the next ten years. GP-write will hold its next meeting in New York City on May 9-10, 2017; please visit this site for more information.  


Global Production


To begin synthesizing a yeast chromosome, researchers must first plan thousands of changes, some of which empower them to move around pieces of chromosomes in a kind of fast, high-powered evolution. Other changes remove stretches of DNA code found to be unlikely to have a functional role by past efforts. The BioStudio software was developed by a team at Johns Hopkins led by Joel Bader.


With the edits made, the team starts to assemble edited, synthetic DNA sequences into ever larger chunks, which are finally introduced into yeast cells, where cellular machinery finishes building the chromosome. A major innovation captured in the current round of papers involves this last step.


Previously, researchers were required to finish building one piece of a chromosome before they could start work on the next. Sequential requirements are bottlenecks, says Boeke, which slow processes and increase cost. The current round of papers features several efforts to “parallelize” the assembly of synthetic chromosomes.

Labs around the globe each synthesized different pieces in strains of yeast that were then mated (crossed) to quickly yield thriving yeast, not just with an entire synthetic chromosome, but in some instances with more than one. Specifically, a paper led by author Leslie Mitchell, PhD, a post-doctoral fellow from Boeke’s lab at NYU Langone, described the construction of a strain containing three synthetic chromosomes.

“Steps can be accomplished at the same time in many locales and then assembled at the end, like networking laptops to create a global super computer,” says Mitchell.

Along the way, the global team honed a number of innovations and came to understand yeast biology better. A team at Tsinghua University, for instance, led an effort where six teams built in pieces synthetic chromosome XII (synXII), which was then assembled into a final molecule more than a million base pairs (a megabase) in length. This largest synthetic chromosome to date is still 1/3,000 of what would be needed to build a human genome molecule, so new techniques will be needed.

In addition, experiments demonstrated that drastic changes can be made to the genomes of yeast without killing them, says Boeke. Yeast strains, for instance, survived experiments where sections of DNA code were moved from one chromosome to another, or even swapped between yeast species, with little effect. Genetically pliable (plastic) organisms make good platforms for the dramatic engineering that may be needed for future applications. The search for differences between the wild type and synthetic chromosomes was taken to new heights by the BGI/Edinburgh effort on synII, which used a “Transomic” approach to deeply profile the DNA, RNA protein and even metabolomics and phenomics, and confirm the “yeastiness” of the altered strain and its chromosomes.


The package of seven newly published had authors from ten universities in several countries, including the US (NYU Langone, Johns Hopkins), China (Tsinghua, Tianjin), France (Institut Pasteur, Sorbonne Universités), and Scotland (Edinburgh); along with authors from key industry partners: BGI, the leading Chinese genomics company, and US/China-based Genscript.


Led by the School of Chemical Engineering and Technology at Tianjin University in China, the paper describing the synthesis of SynV is noteworthy in that is was done by undergraduate students as part of “Build-a-Genome China”, a class first taught in the United States at Johns Hopkins, where Boeke worked before coming to NYU Langone. This is part of an emerging global network of “chromosome foundries,” says Boeke, “which is building the next generation of synthetic biologists along with chromosomes.” The Tianjin group also notably completed two chromosomes, and developed powerful methods for “debugging” errors found in synthetic chromosomes.
In addition to Boeke and Mitchell, lead organizers for the current studies included Ying-Jin Yuan of Tianjin and Junbiao Dai of Tsinghua University, Joel Bader from Johns Hopkins, Romain Koszul at the Institut Pasteur, Yizhi Cai at the University of Edinburgh, and Huanming Yang at BGI. The US studies were supported principally by the National Science Foundation. Other key funding sources were the China National High Technology Research and Development Program, the National Science Foundation of China, the Chinese Ministry of Science and Technology, the UK Biotechnology and Biological Sciences Research Council, and ERASynBio.

NYU Langone Medical Center Press Release

Scientists Synthesize First Functional “Designer” Chromosome in Yeast

Study reports major advance in synthetic biology

March 27, 2014 (All day)

An international team of scientists led by Jef Boeke, PhD, director of NYU Langone Medical Center’s Institute for Systems Genetics, has synthesized the first functional chromosome in yeast, an important step in the emerging field of synthetic biology, designing microorganisms to produce novel medicines, raw materials for food, and biofuels.

Over the last five years, scientists have built bacterial chromosomes and viral DNA, but this is the first report of an entire eukaryotic chromosome, the threadlike structure that carries genes in the nucleus of all plant and animal cells, built from scratch. Researchers say their team’s global effort also marks one of the most significant advances in yeast genetics since 1996, when scientists initially mapped out yeast’s entire DNA code, or genetic blueprint.

“Our research moves the needle in synthetic biology from theory to reality,” says Dr. Boeke, a pioneer in synthetic biology who recently joined NYU Langone from Johns Hopkins University.

“This work represents the biggest step yet in an international effort to construct the full genome of synthetic yeast,” says Dr. Boeke. “It is the most extensively altered chromosome ever built. But the milestone that really counts is integrating it into a living yeast cell. We have shown that yeast cells carrying this synthetic chromosome are remarkably normal. They behave almost identically to wild yeast cells, only they now possess new capabilities and can do things that wild yeast cannot.”

In this week’s issue of Science online March 27, the team reports how, using computer-aided design, they built a fully functioning chromosome, which they call synIII, and successfully incorporated it into brewer’s yeast, known scientifically as Saccharomyces cerevisiae.

The seven-year effort to construct synIII tied together some 273, 871 base pairs of DNA, shorter than its native yeast counterpart, which has 316,667 base pairs. Dr. Boeke and his team made more than 500 alterations to its genetic base, removing repeating sections of some 47,841 DNA base pairs, deemed unnecessary to chromosome reproduction and growth. Also removed was what is popularly termed junk DNA, including base pairs known not to encode for any particular proteins, and “jumping gene” segments known to randomly move around and introduce mutations. Other sets of base pairs were added or altered to enable researchers to tag DNA as synthetic or native, and to delete or move genes on synIII.

“When you change the genome you”re gambling. One wrong change can kill the cell,” says Dr. Boeke. “We have made over 50,000 changes to the DNA code in the chromosome and our yeast still live. That is remarkable. It shows that our synthetic chromosome is hardy, and it endows the yeast with new properties.”

The Herculean effort was aided by some 60 undergraduate students enrolled in the “Build a Genome” project, founded by Dr. Boeke at Johns Hopkins. The students pieced together short snippets of the synthetic DNA into stretches of 750 to 1,000 base pairs or more. These pieces were then assembled into larger ones, which were swapped for native yeast DNA, an effort led by Srinivasan Chandrasegaran, PhD, a professor at Johns Hopkins. Chandrasegaran is also the senior investigator of the team’s studies on synIII.

Student participation kicked off what has become an international effort, called Sc2.0 for short, in which several academic researchers have partnered to reconstruct the entire yeast genome, including collaborators at universities in China, Australia, Singapore, the United Kingdom, and elsewhere in the U.S.

Yeast chromosome III was selected for synthesis because it is among the smallest of the 16 yeast chromosomes and controls how yeast cells mate and undergo genetic change. DNA comprises four letter-designated base macromolecules strung together in matching sets, or base pairs, in a pattern of repeating letters. “A” stands for adenine, paired with “T” for thymine; and “C” represents cysteine, paired with “G” for guanine. When stacked, these base pairs form a helical structure of DNA resembling a twisted ladder.

Yeast shares roughly a third of its 6,000 genes—functional units of chromosomal DNA for encoding proteins — with humans. The team was able to manipulate large sections of yeast DNA without compromising chromosomal viability and function using a so-called scrambling technique that allowed the scientists to shuffle genes like a deck of cards, where each gene is a card. “We can pull together any group of cards, shuffle the order and make millions and millions of different decks, all in one small tube of yeast,” Dr. Boeke says. “Now that we can shuffle the genomic deck, it will allow us to ask, can we make a deck of cards with a better hand for making yeast survive under any of a multitude of conditions, such as tolerating higher alcohol levels.”

Using the scrambling technique, researchers say they will be able to more quickly develop synthetic strains of yeast that could be used in the manufacture of rare medicines, such as artemisinin for malaria, or in the production of certain vaccines, including the vaccine for hepatitis B, which is derived from yeast. Synthetic yeast, they say, could also be used to bolster development of more efficient biofuels, such as alcohol, butanol, and biodiesel.

The study will also likely spur laboratory investigations into specific gene function and interactions between genes, adds Dr. Boeke, in an effort to understand how whole networks of genes specify individual biological behaviors.

Their initial success rebuilding a functioning chromosome will likely lead to the construction of other yeast chromosomes (yeast has a total of 16 chromosomes, compared to humans’ 23 pairs), and move genetic research one step closer to constructing the organism’s entire functioning genome, says Dr. Boeke.

Dr. Boeke says the international team’s next steps involve synthesizing larger yeast chromosomes, faster and cheaper. His team, with further support from Build a Genome students, is already working on assembling base pairs in chunks of more than 10,000 base pairs. They also plan studies of synIII where they scramble the chromosome, removing, duplicating, or changing gene order.

Detailing the Landmark Research Process

Before testing the scrambling technique, researchers first assessed synIII’s reproductive fitness,  comparing its growth and viability in its unscrambled from  — from a single cell to a colony of many cells — with that of native yeast III. Yeast proliferation was gauged under 19 different environmental conditions, including changes in temperature, acidity, and hydrogen peroxide, a DNA-damaging chemical. Growth rates remained the same for all but one condition.

Further tests of unscrambled synIII, involving some 30 different colonies after 125 cell divisions, showed that its genetic structure remained intact as it reproduced. According to Dr. Boeke, individual chromosome loss of one in a million cell divisions is normal as cells divide. Chromosome loss rates for synIII were only marginally higher than for native yeast III.

To test the scrambling technique, researchers successfully converted a non-mating cell with synIII to a cell that could mate by eliminating the gene that prevented it from mating.

Funding support for these experiments was provided by National Science Foundation, the National Institutes of Health, and Microsoft. Corresponding federal grant numbers are MCB-0718846 and GM-077291. Additional funding support was provided by fellowships from La Fondation pour la Recherche Médicale, Pasteur-Roux, National Sciences and Engineering Research Council of Canada, U.S. Department of Energy, and grants from the Exploratory Research Grant from the Maryland Stem Cell Research Fund and the Johns Hopkins University Applied Physics Laboratory.

Besides the teams at NYU Langone and Johns Hopkins, other scientific teams involved in the global Sc2.0 research effort are based at Loyola University in Baltimore, Md; BGI in Shenzhen, China; Tianjin University in China; Tsinghua University in China; MacQuarie University in Sydney, Australia; the Australian Wine Institute in Adelaide, Australia; the National University of Singapore; Imperial College, London, England; and the University of Edinburgh in Scotland.

£1 Million from BBSRC and EPSRC for Synthetic Yeast

David Willetts, Minister for Universities and Science, announced nearly £1M funding for synthetic yeast at the Sixth International Meeting on Synthetic Biology (SB6.0) at Imperial College London on Thursday (July 11). David Willetts said: Sc2.0 project “is truly groundbreaking and pushes the boundaries of synthetic biology. Thanks to this investment, UK scientists will be at the centre of an international effort using yeast – which gives us everything from beer to biofuels – to provide new research techniques and unparalleled insights into genetics. This will impact important industrial sectors like life sciences and agriculture.” Funding for the yeast project is part of a £60M package for synthetic biology.

Dr.Tom Ellis, Lecturer in Synthetic Biology at Imperial College London, said: “We are excited to be welcoming our new international consortium partners to London to discuss Sc2.0. Having recently secured funding for the UK to be part of this ground-breaking project, we are looking forward to getting started and being part of the action. It”s a perfect fit for our work in synthetic biology here at Imperial, where we really view yeast as a tiny factory that can be tooled-up to produce new molecules. A synthetic genome will allow us to reprogram yeast and our goal is to use it to produce new antibiotics as resistance arises to existing ones.”

When completed, synthetic yeast will be the first time scientists have built the whole genome of a eukaryotic organism – those organisms, like animals and plants, which store DNA within a nucleus. Scientists can then design different strains of synthetic yeast that contain genes to make commercially valuable products such as chemicals, vaccines or biofuels.

Professor Boeke, the overall head of the project at Johns Hopkins Medical School in Baltimore, said: “Sc2.0, once completed, will provide unparalleled opportunities for asking profound questions about biology in new and interesting ways, such as: How much genome scrambling generates a new species? How many genes can we delete from the genome and still have a healthy yeast? And how can an organism adapt its gene networks to cope with the loss of an important gene? Moreover, genome scrambling may find many uses in biotechnology, for example in the development of yeast that can tolerate higher ethanol levels.”

Alongside BBSRC and EPSRC, major funders for the Sc2.0 consortium members in their respective countries include the US National Science Foundation (NSF), the US Department of Energy, China”s Ministry of Science and Technology (MoST) and the Tsinghua University Initiative Scientific Research Program.
