This chapter outlines a comprehensive methodology for the design, assembly, and functional assessment of CRISPR/dCas9 systems optimized for tomato to investigate pathogen-associated responses.
The CRISPR-condensate system merges the dramatically enhanced transcriptional efficacy with the reduced complexity of components, providing a modular system for fine-tuned gene expression regulation and makes biomolecular condensation a general principle for enhancing CRISPR gene regulation.
Abstract Selective and tunable regulation of clustered regularly interspaced short palindromic repeats (CRISPR)/Cas12a activity enables on-demand control, yet current strategies remain hindered by nonspecific regulation and limited tunability. Inspired by proximity effect, we present a Cas-regulation-targeting chimera...
The application of genome editing, CRISPR/Cas9 has revolutionized plant breeding by enabling precise, efficient, and targeted modification of native genes, significantly accelerating the development of improved agronomic traits of crops. Therefore, CRISPR/Cas9 technology currently the most extensively used genome editi...
The gene regulatory approaches at the translational and post-translational levels were integrated with optogenetic control patterns to attain very sensitive multi-level precision regulation of the dCas9 protein, thereby facilitating flexible regulation of transcription levels of target genes.
CRISPR interference (CRISPRi) enables programmable and reversible gene repression but often suffers from leakiness in the uninduced state, thereby confounding phenotypes of essential or dosage-sensitive genes. Here, we introduce a novel CRISPRi architecture, in which dCas9 restricts its own expression through a feedbac...
Examination of the predicted secondary structure of the tracrRNA–crRNA duplex suggests that the features required for Cas9-catalyzed DNA cleavage at specific sites can be captured within a single chimeric RNA.
