Biotechnological approaches in glucosinolate production

Area of Science:

• Plant biochemistry
• Metabolic engineering
• Nutraceuticals

Background:

• Glucosinolates (GLSs) are sulfur-rich compounds found in Brassicales plants.
• Historically viewed as anti-nutritional or flavor compounds.
• Emerging evidence highlights their significant human health-promoting properties.

Purpose of the Study:

• To provide a comprehensive overview of biotechnological methods for enhancing glucosinolate production.
• To explore strategies for optimizing GLS content and composition.
• To discuss the application of synthetic biology for GLS generation.

Main Methods:

• Optimization of GLS production in native GLS-producing plants and their cell/hairy root cultures.
• Application of synthetic biology in heterologous hosts, including tobacco, Escherichia coli, and Saccharomyces cerevisiae.
• Review of current research progress in these biotechnological approaches.

Main Results:

• Detailed discussion of various biotechnological strategies for GLS enhancement.
• Comparison of GLS production in native plant systems versus engineered heterologous hosts.
• Assessment of the feasibility and progress of different approaches.

Conclusions:

• Biotechnological approaches offer promising avenues for generating abundant sources of health-promoting glucosinolates.
• Both plant-based systems and microbial hosts are being explored for efficient GLS production.
• Further research in metabolic engineering and synthetic biology is crucial for maximizing GLS benefits.
