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 a 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.
