This study compares CRISPR/Cas9 and CRISPR/Cpf1 genome editing systems in plants. It introduces a new database and desktop software to aid in selecting and applying these powerful CRISPR tools.
Area of Science:
- Genetics and Genomics
- Molecular Biology
- Bioinformatics
Background:
- CRISPR-Cas9 and CRISPR-Cpf1 are powerful genome editing tools with broad applications.
- Limited comparative studies exist for whole-genome applications, especially in plants.
- A need exists for user-friendly, plant-specific CRISPR databases and software.
Purpose of the Study:
- To comprehensively compare CRISPR/Cas9 and CRISPR/Cpf1 systems in plants.
- To analyze key factors influencing CRISPR editing efficiency, including PAM sites, GC content, and G-quadruplex structures.
- To develop accessible bioinformatics resources for plant CRISPR genome editing.
Main Methods:
- Comparative analysis of CRISPR/Cas9 and CRISPR/Cpf1 systems.
- Evaluation of proto-spacer adjacent motif (PAM) site abundance and PAM-rich region (PARR) inhibiting ratio.
- Assessment of GC content, optimal proto-spacer length, and G-quadruplex (G-Q) structures.
- Development of a plant-specific CRISPR database and desktop software.
Main Results:
- Identified similarities and differences between CRISPR/Cas9 and CRISPR/Cpf1 systems.
- Developed a comprehensive CRISPR database with 138 plant genomes.
- Created desktop software for whole-genome CRISPR editing site detection and analysis.
- Provided data to facilitate the selection and application of CRISPR systems in plants.
Conclusions:
- The study offers valuable insights into CRISPR/Cas9 and CRISPR/Cpf1 system characteristics in plants.
- A novel, user-friendly database and software are now available for plant genome editing.
- These resources will aid researchers in efficiently selecting and applying CRISPR technologies in plant science.
