Innovation Solution
The development of the soybean variety 01069686, which incorporates specific genetic modifications through transgenic genes and genome editing techniques, such as Cas endonucleases, to confer traits like herbicide resistance, disease resistance, and improved nutritional quality, along with a breeding program that includes methods like backcrossing and marker-assisted selection to refine desired characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional breeding methods are used to develop soybean varieties with improved traits, then genetic diversity is maintained, but the breeding process requires extensive research and resources with difficult prediction of outcomes
Solution Approach 1:
The patent applies parameter changes by modifying specific genetic loci through genome editing techniques (such as CRISPR/Cas9) to directly alter DNA sequences. This approach changes the fundamental parameter of genetic modification from conventional random mutation and recombination to precise, targeted editing, thereby improving predictability of trait expression while reducing breeding complexity
Solution Approach 2:
The patent replaces the mechanical breeding process (crossing, selection, and generation advancement) with a molecular-level system (genome editing). Instead of relying on traditional mechanical crossing and phenotypic selection over multiple generations, the invention uses molecular tools to directly edit genes, substituting the mechanical breeding system with a more precise molecular intervention system
2Productivity
If multiple traits are combined in a single variety to improve yield and resistance, then agronomic performance is enhanced, but the genetic combinations become increasingly complex and difficult to manage
Solution Approach 1:
The patent applies segmentation by dividing the complex task of multi-trait improvement into separate, manageable genetic loci. Each desired trait (herbicide resistance, disease resistance, yield components) is edited at its specific genomic location independently. This segmentation allows researchers to address each trait separately through targeted genome editing, then combine them in a systematic manner, reducing the overall complexity compared to traditional multi-trait breeding
Solution Approach 2:
The patent applies universality by using a single genome editing platform (such as CRISPR/Cas9) to achieve multiple different traits. The same molecular toolset and general methodology can be applied to edit different genes for herbicide resistance, disease resistance, yield improvement, and other traits, providing a universal solution for multi-trait enhancement rather than requiring separate breeding programs for each trait
3Reliability
If extensive breeding programs are conducted to achieve stable, high-yielding varieties, then trait improvement is possible, but time and resource consumption increase significantly
Solution Approach 1:
The patent applies preliminary action by performing genome editing on early-generation plants (such as F1 or F2) rather than waiting for later generations. By introducing precise genetic modifications early in the breeding process and using techniques like gene stacking or direct selection of edited plants, the program achieves stable trait expression more quickly, reducing the traditional time required for multiple generations of breeding and selection
