Genome Editing Targets for Improving Nutrient Use Efficiency and Nutrient Stress Adaptation

Area of Science:

• Plant Science
• Genetics
• Agricultural Science

Background:

• Nutrient deficiency impacts crop yield and quality.
• Transcription factors and gene networks regulate nutrient homeostasis.
• Improving nutrient use efficiency (NtUE) is vital for sustainable agriculture.

Purpose of the Study:

• Review potential genome editing targets for NtUE.
• Explore strategies for improving nutrient stress tolerance.
• Describe genome editing applications for plant nutrient regulation.

Main Methods:

• CRISPR-Cas9 technology for plant genome editing.
• CRISPR/dead (d) Cas9 for promoter engineering and gene regulation.
• CRISPR activation (CRISPRa) and CRISPR interference (CRISPRi) for gene expression modulation.
• Base editing and prime editing for precise genetic modifications.

Main Results:

• Negative regulators of nutrient signaling are key targets for enhancing nutrient uptake.
• Genome editing strategies can precisely alter gene expression and DNA methylation.
• CRISPR/dCas9 systems facilitate targeted gene overexpression and repression.

Conclusions:

• CRISPR-Cas technology offers powerful tools for developing nutrient-use-efficient plants.
• Targeted genome editing can significantly improve crop tolerance to nutrient stress.
• Advancements in CRISPR-based strategies accelerate genetic improvement for sustainable agriculture.
