CRISPR/Cas-mediated plant genome editing: outstanding challenges a decade after implementation

Trends in Plant Science, Journal Year: 2023, Volume and Issue: 28(10), P. 1144 - 1165

Published: June 16, 2023

The discovery of the CRISPR/Cas genome-editing system has revolutionized our understanding plant genome. been used for over a decade to modify genomes study specific genes and biosynthetic pathways as well speed up breeding in many species, including both model non-model crops. Although is very efficient genome editing, bottlenecks challenges slow down further improvement applications. In this review we discuss that can occur during tissue culture, transformation, regeneration, mutant detection. We also opportunities provided by new CRISPR platforms applications related gene regulation, abiotic biotic stress response improvement, de novo domestication plants.

Beyond knockouts: fine‐tuning regulation of gene expression in plants with CRISPR‐Cas‐based promoter editing

New Phytologist, Journal Year: 2023, Volume and Issue: 239(3), P. 868 - 874

Published: June 6, 2023

The CRISPR-Cas-based genome editing field in plants is expanding rapidly. Editing plant promoters to obtain cis-regulatory alleles with altered expression levels or patterns of target genes a highly promising topic. However, primarily used CRISPR-Cas9 has significant limitations when noncoding sequences like promoters, which have unique structures and regulatory mechanisms, including A-T richness, repetitive redundancy, difficulty identifying key regions, higher frequency DNA structure, epigenetic modification, protein binding accessibility issues. Researchers urgently require efficient feasible tools strategies address these obstacles, enhance promoter efficiency, increase diversity polymorphism, and, most importantly, enable 'non-silent' events that achieve precise gene regulation. This article provides insights into the challenges references for implementing editing-based research plants.

High performance TadA-8e derived cytosine and dual base editors with undetectable off-target effects in plants

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: June 14, 2024

Abstract Cytosine base editors (CBEs) and adenine (ABEs) enable precise C-to-T A-to-G edits. Recently, ABE8e, derived from TadA-8e, enhances edits in mammalian cells plants. Interestingly, TadA-8e can also be evolved to confer editing. This study compares engineered CBEs rice tomato cells, identifying TadCBEa, TadCBEd, TadCBEd_V106W as efficient with high purity a narrow editing window. A dual editor, TadDE, promotes simultaneous Multiplexed TadCBEa TadDE is demonstrated transgenic rice, no off-target effects detected by whole genome transcriptome sequencing, indicating specificity. Finally, two crop engineering applications using are shown: introducing herbicide resistance alleles OsALS creating synonymous mutations OsSPL14 resist OsMIR156 -mediated degradation. Together, this presents editor valuable additions the plant toolbox.

Expanding plant genome editing scope and profiles with CRISPR‐FrCas9 systems targeting palindromic TA sites

Plant Biotechnology Journal, Journal Year: 2024, Volume and Issue: 22(9), P. 2488 - 2503

Published: May 7, 2024

Summary CRISPR‐Cas9 is widely used for genome editing, but its PAM sequence requirements limit efficiency. In this study, we explore Faecalibaculum rodentium Cas9 (FrCas9) plant especially in rice. FrCas9 recognizes a concise 5′‐NNTA‐3′ PAM, targeting more abundant palindromic TA sites genomes than the 5′‐NGG‐3′ of most popular SpCas9. shows cleavage activities at all tested with editing outcomes sharing same characteristics typical system. induces high‐efficiency targeted mutagenesis stable rice lines, readily generating biallelic mutants expected phenotypes. We augment FrCas9's ability to generate larger deletions through fusion exonuclease, TREX2. TREX2‐FrCas9 generates much without compromise demonstrate as an efficient tool genetic knockout microRNA gene. Furthermore, FrCas9‐derived cytosine base editors (CBEs) and adenine (ABE) are developed produce C‐to‐T A‐to‐G edits plants. Whole‐genome sequencing‐based off‐target analysis suggests that highly specific nuclease. Expression plants, however, causes detectable guide RNA‐independent mutations, mostly single nucleotide variants (SNVs). Together, have established CRISPR‐FrCas9 system mutagenesis, large deletions, The simple motif makes promising plants expanded scope.
