Project description:Here we report the design, construction and characterization of a 770 Kb synthetic yeast chromosome II (synII). With the UPLC-MS method, we demonstrated synII maintains a nearly wild-type phenotype and fitness despite hundreds of designer editing to it. Our phenomics, transcriptomics, proteomics data futher supports the identity of synII and wild one.

Project description:Herein we report the successful design, construction and characterization of a 770 kb synthetic yeast chromosome II (synII). Our study incorporates characterization at multiple levels, including phenomics, transcriptomics, proteomics, chromosome segregation and replication analysis to provide the most thorough and comprehensive analysis of a synthetic chromosome. Our “Trans-Omics” analyses reveal a modest but potentially significant pervasive up-regulation of translational machinery observed in synII is mainly caused by the deletion of 13 tRNAs. By both complementation assays and SCRaMbLE, we targeted and debuged the origin of a growth defect at 37°C in glycerol medium, which is related to misregulation of the HOG response. Despite the subtle differences, the synII strain shows highly consistent biological processes comparable to the native strain.

Project description:We designed and synthesized synI, which is ~21.4% shorter than native chrI, the smallest chromosome in Saccharomyces cerevisiae. SynI was designed for attachment to another synthetic chromosome due to concerns surrounding potential instability and karyotype imbalance, and is now attached to synIII, yielding the first synthetic yeast fusion chromosome. We constructed additional fusion chromosomes to investigate effects of fusions on nuclear function. We observed unexpected loops and twisted structures in chrIII-I and chrIX-III-I fusion chromosomes dependent on silencing protein Sir3. ChrI faces special challenges in assuring meiotic crossovers required for efficient homolog disjunction. Centromere deletions engineered into fusion chromosomes revealed opposing effects of core centromeres and pericentromeres in modulating deposition of meiotic recombination protein Red1. These effects extended over >100kb, to disproportionally promote meiotic recombination of small chromosomes like chrI. These findings reveal the power of synthetic genomics to uncover new biology and deconvolute complex biological systems.

Project description:Aneuploidy and aging are correlated; however, a causal link between these two phenomena has remained elusive. Here we show that yeast disomic for a single native yeast chromosome generally have a decreased replicative lifespan. In addition, the extent of this lifespan deficit correlates with the size of the extra chromosome. We identified a mutation in BUL1 that rescues both the lifespan deficit and a protein trafficking defect in yeast disomic for chromosome 5. Bul1 is an E4 ubiquitin ligase adaptor involved in a protein quality-control pathway that targets membrane proteins for endocytosis and destruction in the lysosomal vacuole thereby maintaining protein homeostasis. Concurrent suppression of the aging and trafficking phenotypes suggests that disrupted membrane protein homeostasis in aneuploid yeast may contribute to their accelerated aging. The data reported here demonstrate that aneuploidy can impair protein homeostasis, shorten lifespan, and may contribute to age-associated phenotypes.
