CUBIC: A Versatile Cumate-Based Inducible CRISPRi System in Streptomyces.

ABSTRACT: Streptomyces, a genus of Gram-positive bacteria, is known as nature's medicine maker, producing a plethora of natural products that have huge benefits for human health, agriculture, and biotechnology. To take full advantage of this treasure trove of bioactive molecules, better genetic tools are required for the genetic engineering and synthetic biology of Streptomyces. We therefore developed CUBIC, a novel CUmate-Based Inducible CRISPR interference (CRISPRi) system that allows highly efficient and inducible gene knockdown in Streptomyces. Its broad application is shown by the specific and nondisruptive knockdown of genes involved in growth, development and antibiotic production in various Streptomyces species. To facilitate hyper-efficient plasmid construction,
