• To evaluate the performance of novel gene editing tools in plant molecular biology.
• To identify future research directions in precise plant genetic engineering.

Main Methods:

• Review of recent advancements in plant gene targeting technologies.
• Focus on zinc finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), and CRISPR-Cas systems.
• Analysis of the performance and applications of these gene editing tools in plants.

Main Results:

• Gene targeting techniques enable specific integration of foreign genes into plant genomes.
• ZFNs, TALENs, and CRISPR offer precise genome modification capabilities.
• These novel methods address limitations of random gene insertion in conventional breeding.

Conclusions:

• Gene targeting represents a significant advancement in modern crop breeding.
• CRISPR and related nucleases are powerful tools for precise plant genetic engineering.
