Summary: Clustered regularly interspaced short palindromic repeats and CRISPR-associated proteins (CRISPR-Cas) systems are important tools for plant genome engineering. In this study, the hypercompact Cas phi nuclease is shown to generate stably inherited gene edits in Arabidopsis. The Cas phi protein variants, vCas phi and nCas phi, exhibit higher editing efficiency and no off-target editing was observed. The characteristics of Cas phi, such as its small size, T-rich minimal protospacer adjacent motif (PAM), and wide range of working temperatures, make it an excellent supplement to existing plant genome editing systems.

Summary: CRISPR/Cas systems are promising tools for genome editing. A novel reporter system called BETLE is described, which enables fast, sensitive, and cell-specific detection of genome editing. BETLE includes multiple reporter proteins encoded in different open-reading frames, allowing for the analysis of editing and localization of genome-edited cells. It is a versatile tool that can be used for in vitro evaluation and optimization of CRISPR/Cas genome editing and HDR.

Summary: CRISPR-Cas enables highly efficient genome editing, allowing the introduction of desired modifications such as mutations and deletions. C. elegans has emerged as a significant model organism for CRISPR-Cas, with numerous strategies established. However, the abundance of methods makes it challenging to choose the correct approach, highlighting the importance of selecting appropriate screening methods for genome modification planning.

Summary: The CRISPR-Cas system is an adaptive immune response mechanism in prokaryotes that integrates short sequences of the target genome (spacers) into the CRISPR locus. CRISPR-Cas, classified based on Cas proteins, uses programmable RNAs to target DNA sequences and has become a powerful technique in genome editing. This article discusses the evolution, classification, design, and molecular mechanism of CRISPR-Cas systems, as well as their applications in agriculture and anticancer therapy. It also briefly explores the role of CRISPR and its Cas systems in the diagnosis and prevention of COVID-19, and discusses the challenges and potential solutions in existing CRISPR-Cas technologies.

Summary: Gene editing holds great promise for both the scientific community and society, with CRISPR tools being the key to achieving therapeutic applications. However, initial CRISPR-Cas editing systems have limitations in efficiency and undesired products, leading to the development of various improvements such as base editors and programmable nucleases. Prime editors and dual prime editing systems have also been created to enhance editing outcomes.

Summary: The DNA-dependent protein kinase catalytic subunit (DNA-PKcs) encoded by the PRKDC gene is essential for repairing DNA double-strand breaks in humans. It also has additional roles in transcriptional regulation, telomere protection, chromosomal integrity, and cellular processes. Dysregulation of DNA-PKcs is commonly observed in cancers. Recent studies have found that DNA-PKcs is conserved in green plants but not in angiosperms or basal angiosperms. Challenges in detecting DNA-PKcs sequences in plants are attributed to its long polypeptide and gene length. Alignment of sequences between plants and humans suggests possible structural and functional conservation, highlighting the potential significance of DNA-PKcs in plant biology.
