Genetic Biofortification of Winter Wheat with Selenium (Se)

Area of Science:

• Agricultural Science
• Human Nutrition
• Plant Breeding

Background:

• Wheat is a primary global food source, feeding 30-40% of the world's population.
• Low micronutrient levels in wheat grains contribute to widespread deficiencies, particularly of iron (Fe), zinc (Zn), and selenium (Se).
• Selenium deficiency poses significant health risks to both humans and animals.

Purpose of the Study:

• To highlight the importance of wheat biofortification for addressing global micronutrient deficiencies.
• To identify genetic improvement as the most efficient and sustainable approach for enhancing wheat's nutritional value.

Main Methods:

• Review of existing literature on wheat nutritional content and biofortification strategies.
• Analysis of the limitations of agronomic biofortification methods.
• Emphasis on genetic enhancement for improved micronutrient accumulation in wheat grains.

Main Results:

• Wheat's global dominance makes it an ideal candidate for biofortification.
• Genetic improvement is presented as a more economical and environmentally sound approach compared to agronomic methods.
• Enhanced micronutrient content in wheat can significantly improve public health outcomes.

Conclusions:

• Genetic biofortification of wheat is essential for combating global micronutrient deficiencies.
• Improving selenium (Se) content in wheat grains is a key target for public health.
• Sustainable strategies are needed to enhance the nutritional quality of staple crops like wheat.
