This article mainly introduces the application of CRISPR/Cas9 technology in cellulase engineering in T. reesei. The emergence of new genetic tools over the past decade has strengthened the understanding of the transcription mechanism of cellulase genes in fungi and provided a method for editing them at the molecular level. However, the application of CRISPR technology in fungi still faces challenges and limitations.
Trichoderma reesei has been explored intensively in the laboratory and on an industrial scale for its highly potent cellulase secretion machinery since its characterization over 70 years ago. Emergence of new genetic tools over the past decade has strengthened the understanding of mechanism involved in transcription of cellulase genes in fungi and provided a boost to edit them at molecular level. Since several transcriptional factors work synergistically for cellulase expression in fungi; engineering of cellulase secretome for enhanced cellulase titer require combined manipulation of these factors. In the same context, CRISPR/Cas9 has emerged as a powerful, versatile genetic engineering tool for multiplex gene editing in fungi. It is true that considerable efforts with CRISPR technologies have largely developed fungal genetic engineering, but its application in fungi is still challenging and limited. The present review illustrates the precision, strengths and challenges of using CRISPR/Cas9 technology for cellulase engineering in T. reesei, highlighting key strategies that could be employed for strain improvement.
