From Lab to Field: CRISPRing Major Cultivated Solanaceae for Crop Improvement

Area of Science:

• Agricultural Science
• Molecular Biology
• Biotechnology

Background:

• The Solanaceae family, including tomato, potato, pepper, and eggplant, is crucial for global agriculture.
• CRISPR/Cas genome editing has revolutionized functional genomics and crop improvement due to its precision and efficiency.

Purpose of the Study:

• To provide a comprehensive overview of CRISPR/Cas-mediated genome editing technologies.
• To explore the applications of these technologies in major cultivated Solanaceae crops.
• To discuss emerging strategies and the regulatory landscape for genome-edited crops.

Main Methods:

• Review of CRISPR/Cas9 systems for gene knockout and knock-in.
• Exploration of precision editing strategies like base editing and prime editing.
• Discussion of alternative CRISPR systems (e.g., Cas12a, Cas13) and delivery methods (e.g., VIGE, grafting).

Main Results:

• CRISPR/Cas systems enable targeted gene modifications in Solanaceae crops.
• Advanced techniques like base and prime editing allow precise nucleotide substitutions.
• Novel delivery strategies facilitate the generation of transgene-free edited plants.

Conclusions:

• Genome editing holds significant potential for sustainable agriculture and improving Solanaceae crops.
• Despite regulatory hurdles, genome-edited crops are reaching the market, demonstrating their viability.
• Continued research and development in genome editing technologies are essential for future crop improvement.
