Given their lignocellulose degradability and biocontrol activities, fungi of the ubiquitously distributed genus Trichoderma have multiple industrial and agricultural applications. Genetic manipulation plays a valuable role in tailoring novel engineered strains with enhanced target traits. Nevertheless, as applied to fungi, the classic tools of genetic manipulation tend to be time‐consuming and tedious. However, the recent development of the CRISPR‐Cas system for gene editing has enabled researchers to achieve genome‐wide gene disruptions, gene replacements, and precise editing, and this technology has emerged as a primary focus for novel developments in engineered strains of Trichoderma. Here, we provide a brief overview of the traditional approaches to genetic manipulation, the different strategies employed in establishing CRSIPR‐Cas systems, the utilization of these systems to develop engineered strains of Trichoderma for desired applications, and the future trends in biotechnology. The recent development of the CRISPR‐Cas system for gene editing has enabled researchers to achieve genome‐wide gene disruptions, gene replacements and precise editing, and this technology has emerged as a primary focus for novel developments in engineered strains of Trichoderma.
