Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new soybean cultivars is unpredictable and requires intensive research due to vast genetic diversity and self-pollination, making it challenging to produce consistent and desirable traits such as disease resistance, insect resistance, and environmental adaptability efficiently.
Innovation Solution
The introduction of transgenic genes and site-specific recombination systems like FRT and Cre/Lox into soybean cultivars CL1941276, CL1941547, CL1941920, CL1941244, and CL1941256 to confer traits like herbicide resistance, fungal resistance, and altered oil profiles, combined with breeding methods like marker-assisted selection and backcrossing to achieve desired genetic combinations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional breeding methods are used to develop new soybean cultivars, then genetic diversity is maintained, but the process becomes unpredictable and requires intensive research
Solution Approach 1:
Site-specific recombination systems (FRT, Cre/Lox) act as intermediaries to enable precise genetic modifications. These systems allow breeders to introduce specific traits at predetermined locations in the genome, serving as a mediator between traditional breeding and genetic engineering approaches, thereby achieving both genetic diversity and predictability
Solution Approach 2:
The patent establishes predetermined genetic loci with site-specific recombination sites before breeding begins. This preliminary preparation allows for controlled introduction of desired traits later in the breeding process, making the outcome predictable while maintaining genetic diversity through selective combination of traits
2Adaptability or versatility
If multiple desired traits are introduced into soybean cultivars, then resistance and nutritional qualities are enhanced, but the breeding process complexity increases
Solution Approach 1:
The breeding process is segmented into distinct modular steps: establishing base lines with specific recombination sites, introducing individual traits through controlled crosses, and combining multiple traits in subsequent generations. This segmentation allows complex multi-trait development to be managed as a series of simpler, controlled operations
Solution Approach 2:
Site-specific recombination systems serve as intermediaries that simplify the integration of multiple traits. By providing predetermined insertion sites, these systems eliminate the need for complex random insertion processes, making multi-trait breeding more systematic and manageable
3Stability of the object's composition
If self-pollination is utilized in soybean breeding, then genetic stability is maintained, but cross-pollination efficiency is reduced
Solution Approach 1:
The patent establishes inbred lines with predetermined site-specific recombination sites before crossing. This preliminary genetic stabilization ensures that when cross-pollination occurs, the background genetics are stable and uniform, allowing efficient selection of offspring with desired trait combinations while maintaining overall genetic stability
