Induced Evolution of Synthetic Yeast genomes (IESY) will use the first synthetic eukaryote, Saccharomyces cerevisiae 2.0 (Sc2.0), as a platform for metabolic engineering and genome minimization, and more importantly for generating and understanding industrially high-value phenotypes. Synthetic chromosomes in Sc2.0 permit rapid and comprehensive genome evolution through synthetic chromosome rearrangement and modification by loxP-mediated evolution (SCRaMbLE). SCRaMbLE will be exploited here to evolve strains selected for high-value phenotypes for biofuels and biotechnology, using both chemostats and batch transfer methods in the USA and Europe. Technologies for neochromosomes and orthogonal SCRaMbLE of gene classes will be developed. Evolutionary trajectories will be analysed to relate genome structure with genome function: DNA sequencing will reveal the genome sequence, rearrangements, and copy number changes in the evolved strains; chromosome conformation capture will show how massive rearrangements affect 3D structure; and deep sequencing technologies will relate sequence and structure to gene expression and isoform abundance. Computational analysis will identify the evolutionary drivers for high fitness, with the potential for further optimization. IESY builds on resources uniquely available from the international Sc2.0 consortium and will be an international resource for efficient evolution of high-value phenotypes. This project represents a new paradigm in synthetic biology in which a genome is pre-programmed to explore combinatorial diversity space to evolve new and useful function.

诱导的合成酵母基因组（IESY）的演变将使用第一个合成真核生物酿酒酵母2.0（SC2.0）作为代谢工程和基因组最小化的平台，更重要的是生成和理解工业高价值表型。 SC2.0中的合成染色体可以通过LOXP介导的进化（Scramble）进行合成染色体重排和修饰，可以快速而全面的基因组进化。在这里，将使用Chemofule和生物技术的高价值表型，使用Chemodotats和Chemotatats和批处理转移方法在这里开发争夺，以进化为生物燃料和生物技术的高价值表型的发展。将开发针对基因类别的新染色体和正交拼凑的技术。将分析进化轨迹，以将基因组结构与基因组功能相关联：DNA测序将揭示进化菌株中的基因组序列，重排和拷贝数变化；染色体构象捕获将显示大量重排如何影响3D结构；深层测序技术将序列和结构与基因表达和同工型丰度相关联。计算分析将确定高健身的进化驱动因素，并具有进一步优化的潜力。 Iesy建立在国际SC2.0联盟中独特获得的资源基础上，将成为有效发展高价值表型的国际资源。该项目代表了合成生物学的一个新范式，其中预先编程了基因组来探索组合多样性空间以发展新的和有用的功能。
