    Description: Rapid advances in DNA synthesis techniques have made it possible to engineer viruses, biochemical pathways and assemble bacterial genomes. Here, we report the synthesis of a functional 272,871-base pair designer eukaryotic chromosome, synIII, which is based on the 316,617-base pair native Saccharomyces cerevisiae chromosome III. Changes to synIII include TAG/TAA stop-codon replacements, deletion of subtelomeric regions, introns, transfer RNAs, transposons, and silent mating loci as well as insertion of loxPsym sites to enable genome scrambling. SynIII is functional in S. cerevisiae. Scrambling of the chromosome in a heterozygous diploid reveals a large increase in a-mater derivatives resulting from loss of the MATalpha allele on synIII. The complete design and synthesis of synIII establishes S. cerevisiae as the basis for designer eukaryotic genome biology.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4033833/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4033833/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Annaluru, Narayana -- Muller, Heloise -- Mitchell, Leslie A -- Ramalingam, Sivaprakash -- Stracquadanio, Giovanni -- Richardson, Sarah M -- Dymond, Jessica S -- Kuang, Zheng -- Scheifele, Lisa Z -- Cooper, Eric M -- Cai, Yizhi -- Zeller, Karen -- Agmon, Neta -- Han, Jeffrey S -- Hadjithomas, Michalis -- Tullman, Jennifer -- Caravelli, Katrina -- Cirelli, Kimberly -- Guo, Zheyuan -- London, Viktoriya -- Yeluru, Apurva -- Murugan, Sindurathy -- Kandavelou, Karthikeyan -- Agier, Nicolas -- Fischer, Gilles -- Yang, Kun -- Martin, J Andrew -- Bilgel, Murat -- Bohutski, Pavlo -- Boulier, Kristin M -- Capaldo, Brian J -- Chang, Joy -- Charoen, Kristie -- Choi, Woo Jin -- Deng, Peter -- DiCarlo, James E -- Doong, Judy -- Dunn, Jessilyn -- Feinberg, Jason I -- Fernandez, Christopher -- Floria, Charlotte E -- Gladowski, David -- Hadidi, Pasha -- Ishizuka, Isabel -- Jabbari, Javaneh -- Lau, Calvin Y L -- Lee, Pablo A -- Li, Sean -- Lin, Denise -- Linder, Matthias E -- Ling, Jonathan -- Liu, Jaime -- Liu, Jonathan -- London, Mariya -- Ma, Henry -- Mao, Jessica -- McDade, Jessica E -- McMillan, Alexandra -- Moore, Aaron M -- Oh, Won Chan -- Ouyang, Yu -- Patel, Ruchi -- Paul, Marina -- Paulsen, Laura C -- Qiu, Judy -- Rhee, Alex -- Rubashkin, Matthew G -- Soh, Ina Y -- Sotuyo, Nathaniel E -- Srinivas, Venkatesh -- Suarez, Allison -- Wong, Andy -- Wong, Remus -- Xie, Wei Rose -- Xu, Yijie -- Yu, Allen T -- Koszul, Romain -- Bader, Joel S -- Boeke, Jef D -- Chandrasegaran, Srinivasan -- 092076/Wellcome Trust/United Kingdom -- GM077291/GM/NIGMS NIH HHS/ -- R01 GM077291/GM/NIGMS NIH HHS/ -- R01 GM090192/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2014 Apr 4;344(6179):55-8. doi: 10.1126/science.1249252.

    Description: Recent advances in DNA synthesis technology have enabled the construction of novel genetic pathways and genomic elements, furthering our understanding of system-level phenomena. The ability to synthesize large segments of DNA allows the engineering of pathways and genomes according to arbitrary sets of design principles. Here we describe a synthetic yeast genome project, Sc2.0, and the first partially synthetic eukaryotic chromosomes, Saccharomyces cerevisiae chromosome synIXR, and semi-synVIL. We defined three design principles for a synthetic genome as follows: first, it should result in a (near) wild-type phenotype and fitness; second, it should lack destabilizing elements such as tRNA genes or transposons; and third, it should have genetic flexibility to facilitate future studies. The synthetic genome features several systemic modifications complying with the design principles, including an inducible evolution system, SCRaMbLE (synthetic chromosome rearrangement and modification by loxP-mediated evolution). We show the utility of SCRaMbLE as a novel method of combinatorial mutagenesis, capable of generating complex genotypes and a broad variety of phenotypes. When complete, the fully synthetic genome will allow massive restructuring of the yeast genome, and may open the door to a new type of combinatorial genetics based entirely on variations in gene content and copy number.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3774833/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3774833/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dymond, Jessica S -- Richardson, Sarah M -- Coombes, Candice E -- Babatz, Timothy -- Muller, Heloise -- Annaluru, Narayana -- Blake, William J -- Schwerzmann, Joy W -- Dai, Junbiao -- Lindstrom, Derek L -- Boeke, Annabel C -- Gottschling, Daniel E -- Chandrasegaran, Srinivasan -- Bader, Joel S -- Boeke, Jef D -- AG023779/AG/NIA NIH HHS/ -- R01 AG023779/AG/NIA NIH HHS/ -- R37 AG023779/AG/NIA NIH HHS/ -- England -- Nature. 2011 Sep 14;477(7365):471-6. doi: 10.1038/nature10403.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉High Throughput Biology Center, Johns Hopkins University School of Medicine, 733 North Broadway, Baltimore, Maryland 21205, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21918511" target="_blank"〉PubMed〈/a〉
