Summary
Plant-derived peptides offer eco-friendly biopesticides and biostimulants (BioP&S) to reduce chemical pesticide reliance. Integrating AI, nanotechnology, and synthetic biology can overcome barriers to their development and application in agriculture.
Area of Science:
- Agricultural Science
- Biotechnology
- Plant Science
Background:
- Global agriculture's reliance on chemical pesticides poses environmental and health risks.
- Plant-derived peptides (phytopeptides) are natural regulators with potential as biodegradable biopesticides and biostimulants (BioP&S).
- Commercialization of phytopeptide BioP&S is hindered by limited research, high costs, and undefined applications.
Purpose of the Study:
- To overview emerging discoveries in phytopeptide BioP&S.
- To propose integrated frameworks for phytopeptide development and application.
- To address bottlenecks in phytopeptide commercialization for sustainable agriculture.
Main Methods:
- Literature review and synthesis of current research on plant peptides.
- Exploration of emerging technologies: AI, nanotechnology, and synthetic biology.
- Development of integrated frameworks for identification, design, biomanufacturing, and ecological assessment.
Main Results:
- Phytopeptides present a promising avenue for eco-friendly agricultural inputs.
- Emerging technologies can accelerate discovery, enhance efficacy, and enable industrial production.
- Integration with precision agriculture and compatible crop management is key for maximizing performance.
Conclusions:
- Phytopeptide BioP&S can enhance crop resilience, productivity, and quality sustainably.
- Interdisciplinary innovation and policy support are crucial for unlocking their full potential.
- Strategic integration of phytopeptides with germplasm and crop needs is essential for success.

02:35Key Elements for Plant Nutrition
23.9K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.

Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
