Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods lack effective regulators for modifying plant root architecture and enhancing drought tolerance, and there is a need for novel tools to control unwanted plant growth.
Innovation Solution
Exogenous application of beta-carotene-derived apocarotenoids to plants, which act as plant growth regulators, modifying root architecture and improving drought tolerance, and can be used to control harmful plant growth by altering root depth and density.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional plant growth regulators are used, then root growth can be modulated, but effectiveness in enhancing drought tolerance and modifying root architecture is insufficient
Solution Approach 1:
The patent applies parameter changes by utilizing beta-carotene-derived apocarotenoids that modify root architecture through specific biochemical pathways. These compounds change the physiological parameters of root growth, depth, and branching patterns, thereby enhancing drought tolerance while providing versatile root architecture modification capabilities that conventional regulators cannot achieve
2Manufacturing precision
If existing root growth modulators are applied, then some root development effects are achieved, but precision and effectiveness in controlling root depth and density are inadequate
Solution Approach 1:
The apocarotenoids enable precise control of root depth and density by acting on specific developmental stages and cellular processes. This precision in parameter control translates to improved crop productivity by optimizing water and nutrient uptake efficiency, thereby resolving the contradiction between control precision and yield improvement
3Reliability
If natural signaling molecules are used to enhance stress tolerance, then drought resistance improves, but the ability to control harmful plant growth is limited
Solution Approach 1:
The patent applies universality by demonstrating that apocarotenoids serve multiple functions: they enhance stress tolerance in crop plants while simultaneously acting as herbicidally active compounds that control harmful plant growth. This multi-functionality resolves the contradiction by allowing the same compound to benefit crops while suppressing weeds
