Innovation Solution
The development of the soybean variety 01068972, which incorporates a single locus conversion through genetic transformation, conferring traits like herbicide resistance, disease resistance, and improved nutritional quality, using methods such as genome editing with engineered nucleases, and the use of specific transgenic genes like those from events MON89788 and MON87708.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional breeding techniques are used to combine multiple improved traits, then the breeding process becomes increasingly complex and time-consuming, but the ability to effectively combine traits such as disease resistance, drought tolerance, and herbicide resistance remains limited
Solution Approach 1:
The patent applies parameter changes by using genetic transformation to directly modify the genetic composition of soybean plants, introducing specific genes for desired traits such as herbicide resistance (e.g., EPSPS gene for glyphosate resistance) and disease resistance. This transforms the breeding approach from gradual phenotypic selection to precise genotypic modification, enabling effective combination of multiple traits without proportional increase in process complexity
Solution Approach 2:
The patent uses genetic transformation technology as an intermediary mechanism to transfer desired traits from donor plants to soybean varieties. This intermediary process allows direct introduction of specific genes (such as transgenic events MON89788 and MON87708 mentioned in the patent) rather than relying on traditional crossbreeding, thereby achieving efficient trait combination without the complexity of managing multiple generations of crosses and selections
2Productivity
If conventional breeding methods are used to develop stable, high-yielding varieties, then the time required for variety development increases, but the yield and stability improvements are difficult to achieve simultaneously
Solution Approach 1:
The patent applies preliminary action by pre-selecting and characterizing donor plants with specific desirable traits (such as herbicide resistance, disease resistance, and high yield) before transformation. The patent describes selecting donor plants based on their phenotypic characteristics and genetic background, then using these pre-characterized plants as sources for genetic transformation. This preliminary preparation reduces the time required for subsequent breeding steps compared to starting from scratch with conventional methods
Solution Approach 2:
The patent replaces the mechanical system of traditional crossbreeding (involving manual emasculation, pollination, and multi-generational selection) with genetic transformation technology. This substitution allows direct introduction of desired traits through DNA transfer and expression, bypassing the time-consuming processes of traditional hybridization and selection, thereby significantly improving breeding efficiency and reducing development time
3Reliability
If multiple traits are introduced through genetic transformation, then the nutritional quality and agronomic performance improve, but the complexity of characterizing and validating the transformed variety increases
Solution Approach 1:
The patent applies segmentation by addressing trait validation in discrete, manageable steps: (1) confirming transformation through molecular markers and PCR analysis, (2) evaluating individual agronomic traits separately (yield, height, maturity), (3) assessing specific resistance traits through controlled challenges, and (4) analyzing compositional traits through biochemical assays. This segmented approach to characterization makes the validation process systematic and manageable despite the presence of multiple introduced traits
Solution Approach 2:
The patent employs feedback mechanisms in the characterization process by using molecular markers linked to specific transgenic events (such as events MON89788 and MON87708) to confirm the presence and stability of introduced genes. The patent describes using marker-assisted selection and verification at multiple stages to ensure that the transformed variety maintains the desired traits consistently, providing feedback on the success of the transformation and enabling corrective actions if needed
