The de novo design and synthesis of yeast chromosome XIII facilitates investigations on aging
In the era of synthetic biology, design, construction, and utilization of synthetic chromosomes with unique features provide a strategy to study complex cellular processes such as aging. Herein, we successfully construct the 884 Kb synXIII of Saccharomyces cerevisiae to investigate replicative aging using these synthetic strains. We verify that up-regulation of a rRNA-related transcriptional factor, RRN9, positively influence replicative lifespan. Using SCRaMbLE system that enables inducible whole-genome rearrangement on synXIII, we obtain 20 SCRaMbLEd synXIII strains with extended lifespan. Transcriptome analysis reveal the expression of genes involve in global protein synthesis is up-regulated in longer-lived strains. We establish causal links between genotypic change and the long-lived phenotype via reconstruction of some key structural variations observed in post-SCRaMbLE strains and further demonstrate combinatorial effects of multiple aging regulators on lifespan extension. Our findings underscore the potential of synthetic yeasts in unveiling the function of aging-related genes.
