CRISPR-Cas9 technology, with its unparalleled precision and efficiency, has revolutionized the field of genome editing. In Bacillus thuringiensis (Bt), widely used as a biopesticide, genome editing holds great promise for significantly enhancing its efficacy and functional understanding. This study provides an overview of the mechanisms and advancements of CRISPR-Cas9, comparing it with other genome editing technologies. It delves into its applications in Bt, including gene knockout, knock-in strategies, multiplex genome editing, and targeted mutagenesis. Additionally, it explores the functional studies of Bt genes, covering gene function identification, overexpression, gene silencing, and toxin gene analysis. This study discusses methodological advancements and challenges such as delivery methods, off-target effects, and optimization. Case studies showcase successful gene editing examples, insights gained, and best practices. It also examines ethical and regulatory issues as well as public perception. Finally, it discusses future directions, emerging trends, novel applications, and the potential impact on industrial and agricultural biotechnology. Continuous research and development in CRISPR-Cas9 technology are crucial to fully realizing its potential in Bt genome editing.
