Enhancing quality traits in staple crops: current advances and future perspectives

Area of Science:

• Agricultural Science
• Plant Molecular Biology
• Nutritional Science

Background:

• Staple crops like rice, wheat, and maize are fundamental to global food security.
• Enhancing the quality of these crops presents significant scientific and agricultural challenges.

Purpose of the Study:

• To review recent advancements in improving crop quality traits.
• To identify key molecular mechanisms and unresolved questions in crop quality enhancement.
• To explore strategies for developing high-yield, high-quality crop varieties.

Main Methods:

• Literature review of recent research on crop quality enhancement.
• Focus on molecular mechanisms of endosperm filling, starch synthesis, and protein body formation.
• Analysis of carbon and nitrogen metabolism interactions.

Main Results:

• Summarized progress in understanding endosperm filling, starch granule synthesis, and protein body formation.
• Highlighted ten unresolved questions concerning starch-protein distribution, epigenetics, and environmental impacts.
• Identified opportunities through multi-omics and rational design for "super-crop" development.

Conclusions:

• Advancements in molecular biology and multi-omics offer pathways to enhance crop nutritional value and consumer appeal.
• Addressing unresolved questions is critical for developing sustainable agricultural practices.
• Developing superior crop varieties supports both food security and environmental conservation goals.
