Innovation Solution
The development of the soybean variety 01072220, which incorporates a single locus conversion through genetic transformation, conferring traits like herbicide resistance, disease resistance, and improved nutritional quality, using methods such as backcrossing and genetic marker-assisted selection, and involves the use of transgenic genes and engineered nucleases for genome editing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional breeding techniques are used to combine improved traits, then breeding stability is maintained, but the ability to effectively combine multiple traits such as disease resistance, drought tolerance, and herbicide resistance is limited
Solution Approach 1:
The patent uses molecular markers as intermediaries to bridge the gap between conventional breeding and trait selection. These markers serve as detectable proxies for desired traits, enabling breeders to select for multiple complex traits simultaneously through marker-assisted selection rather than relying solely on phenotypic observation and multiple generations of crossing.
Solution Approach 2:
The patent replaces the mechanical/time-intensive process of conventional phenotypic selection with molecular detection methods. Instead of manually tracking trait inheritance through multiple generations of crossing and phenotypic evaluation, the invention uses DNA-based molecular markers to directly detect and select for desired traits at the genetic level, significantly accelerating the breeding process.
2Productivity
If genetic transformation and genome editing are employed to introduce improved traits, then breeding efficiency and trait combination are enhanced, but the complexity of the breeding process increases
Solution Approach 1:
The patent performs preliminary genetic modification through genome editing to directly introduce desired traits into the soybean variety. Rather than relying on slow conventional crossing and selection processes, the invention uses CRISPR/Cas9 or similar genome editing tools to make precise genetic modifications in advance, creating varieties with desired traits such as herbicide resistance or improved nutritional content in a single step or few generations.
Solution Approach 2:
The patent changes the fundamental parameter of how genetic traits are introduced and selected. Instead of using traditional phenotypic selection parameters that require multiple generations, the invention switches to molecular marker detection parameters that allow direct genetic analysis. This parameter change enables simultaneous selection for multiple traits and dramatically reduces the time and complexity of the breeding process.
3Reliability
If single locus conversion through genetic transformation is used, then specific traits such as herbicide resistance and improved nutritional quality are achieved, but the manufacturing precision and stability of the variety may be affected
Solution Approach 1:
The patent replaces imprecise conventional breeding methods with precise genome editing technologies. Instead of relying on random mutations or complex multi-locus inheritance patterns that are difficult to control, the invention uses CRISPR/Cas9 or TALEN systems to make targeted, precise edits at specific genomic locations. This substitution of methodology achieves both high precision in trait introduction and stability in trait expression across generations.
Solution Approach 2:
The patent uses molecular markers as intermediaries to ensure precise and stable genetic modifications. These markers serve as verification tools to confirm that the desired genetic changes have been successfully introduced and are being properly expressed. The markers provide a reliable link between the genetic modification event and the phenotypic outcome, ensuring both precision and stability.
