Abstract

Saccharomyces cerevisiae has been extensively studied and applied as a model microbial platform for efficient and sustainable production of biofuels, chemicals and natural products. In recent years, the application of CRISPR system in genome editing and transcriptional regulation has greatly improved the efficiency of microbial genome editing. To achieve transcriptional regulation the CRISPR/dCpf1-mediated CRISPRa/i transcriptional regulation system was constructed in this study. By constructing crRNA arrays and adding different activation proteins, repression efficiencies from 62% to 177% for the CRISPRi system and activation efficiencies from 154% to 320% for the CRISPRa system were achieved in the eGFP gene reporter system.
