Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional breeding methods are used to develop sweet corn hybrids, then genetic diversity and trait integration are improved, but breeding time and complexity increase
Solution Approach 1:
The patent applies genome editing technology to directly modify specific genetic parameters and traits in sweet corn plants, bypassing the need for traditional multi-generational crossing and selection. This allows precise changes to be made in a single generation, dramatically reducing breeding time while achieving the desired trait integration that would otherwise require extensive conventional breeding programs.
2Adaptability or versatility
If multiple traits are integrated into sweet corn hybrids through traditional breeding, then plant versatility is improved, but genetic stability may be compromised
Solution Approach 1:
The patent uses genome editing to make localized, precise modifications to specific genes or genomic regions responsible for desired traits, while leaving the rest of the genome unchanged. This approach integrates multiple traits through targeted edits rather than extensive crossing, maintaining genetic stability in the overall genome while achieving the desired multi-trait integration through precise local changes.
3Loss of time
If genome editing is used to modify sweet corn plants, then breeding time is reduced, but regulatory and public acceptance challenges increase
Solution Approach 1:
The patent employs CRISPR-Cas9 genome editing technology, which uses transient guide RNAs and Cas9 proteins that degrade after performing their editing function. This disposable nature of the editing machinery simplifies regulatory considerations compared to transgenic approaches, as no foreign DNA remains in the final product, potentially reducing regulatory complexity despite the advanced technology used.
