Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Soybean breeding faces challenges in predicting phenotypic expression due to genetic complexity and environmental factors, making it difficult to replicate varieties using the same parents and methodology, resulting in unique and unpredictable outcomes.
Innovation Solution
Development of the soybean variety DLL1289, which includes a transgene conferring herbicide resistance and other desirable traits, allowing for self-pollination, backcrossing, and hybrid production to create stable and superior soybean plants with specific characteristics, including herbicide resistance, disease resistance, and enhanced nutritional quality, through methods like microprojectile-mediated delivery and Agrobacterium-mediated transformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional soybean breeding methods are used with the same parents and methodology, then the breeding process should be replicable, but due to genetic complexity and environmental factors, the phenotypic expression cannot be predicted and varieties cannot be replicated
Solution Approach 1:
The patent applies parameter changes by introducing transgenes that confer specific traits (herbicide resistance, disease resistance, nutritional quality) to modify the genetic parameters of the soybean variety. This allows precise control over certain characteristics while managing the complexity through molecular-level interventions rather than relying solely on conventional phenotypic selection.
2Adaptability or versatility
If transgenes are introduced through genetic engineering, then specific traits like herbicide resistance can be conferred, but the complexity of the breeding process increases
Solution Approach 1:
The patent uses transgenes as intermediary elements that carry specific functional traits (such as herbicide resistance via the bar gene or disease resistance via R genes) into the soybean genome. These transgenes act as mediators between the desired trait and the plant, allowing precise trait insertion without requiring complex multi-step breeding procedures for each individual trait.
Solution Approach 2:
The patent demonstrates multi-functionality by integrating multiple transgenes into a single variety that confer different traits (herbicide resistance, disease resistance, nutritional quality). This universal approach allows one variety to embody multiple desired characteristics simultaneously, reducing the need for separate breeding programs for each trait.
3Adaptability or versatility
If multiple transgenes are introduced to confer multiple traits, then the variety becomes more versatile, but the manufacturing precision of the genetic modification decreases
Solution Approach 1:
The patent applies segmentation by introducing multiple distinct transgenes, each responsible for a specific trait (e.g., bar gene for herbicide resistance, R genes for disease resistance, nutritional quality genes). This modular approach allows independent control and optimization of each trait while maintaining overall versatility, as each transgene can be independently characterized and managed.
