Amino Acid Plant Immune Inducers for Stress Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural plants face significant challenges from abiotic stresses such as drought, high and low temperatures, and soil salinization, as well as biotic stresses like diseases and insect pests, leading to substantial losses in crop production. Current methods of pest control, relying heavily on chemical pesticides, are unsustainable and often lead to resistance issues.
Innovation Solution
The use of 2-amino-3-phenylbutyric acid and 2,6-diamino-3-methylhexanoic acid as natural plant immune resistance inducers, isolated from the plant pathogenic fungus Alternata sp., which stimulate the plant's natural immune system to enhance resistance to both biotic and abiotic stresses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chemical pesticides are used to control diseases and insect pests, then crop protection is achieved, but resistance development and environmental pollution occur
Solution Approach 1:
The patent applies the self-service principle by using plant immune resistance inducers that stimulate the plant's own immune system to produce protective substances. Instead of externally applying chemical pesticides that directly kill pests, the inducer activates the plant's endogenous defense mechanisms, making the plant serve its own protection needs and reducing dependence on external chemical agents.
Solution Approach 2:
The patent uses plant immune resistance inducers as intermediary substances that mediate between the plant and pathogens. These inducers do not directly kill pests but rather facilitate the plant's immune response, acting as a bridge that triggers the production of protective compounds without causing direct harm to the plant or environment.
2Reliability
If multiple chemical fungicides are applied to prevent diseases, then disease control is improved, but biodiversity reduction and food safety issues arise
Solution Approach 1:
The patent enables plants to protect themselves by applying immune resistance inducers that activate their endogenous defense systems. This self-service approach eliminates the need for multiple chemical fungicides, thereby preserving biodiversity and ensuring food safety while maintaining effective disease control through the plant's own protective mechanisms.
3Adaptability or versatility
If plants are exposed to multiple abiotic stresses simultaneously, then survival is tested, but damage severity increases
Solution Approach 1:
The patent applies preliminary action by using plant immune resistance inducers to prime the plant's defense system before stress exposure. The inducer activates immune pathways and protective mechanisms in advance, so when multiple abiotic stresses occur simultaneously, the plant is already prepared with enhanced resistance, reducing the severity of damage rather than reacting after damage occurs.

AI summary
The use of 2-amino-3-phenylbutyric acid or 2,6-diamino-3-methylhexanoic acid as a plant immune resistance inducer. The development of 2-amino-3-phenylbutyric acid and/or 2,6-diamino-3-methylhexanoic acid as an active substance into a plant immune resistance inducer can be used to improve the resistance of plants to biotic and abiotic stresses, effectively prevent the infection and reduce the pathogenic levels of fungi, viruses, and bacteria on plants; Meanwhile, they can significantly improve the resistance of plants to high temperature, low temperature, drought and salt stresses. 2-amino-3-phenylbutyric acid and 2,6-diamino-3-methylhexanoic acid have the features of being safe, environmentally friendly and efficient.
