Engineering Contradiction Analysis
1Productivity
If conventional breeding and traditional agricultural practices are used, then crop yields can be maintained under optimal conditions, but productivity decreases under stress conditions such as drought or nitrogen limitation
Solution Approach 1:
The patent changes the physiological parameters of plants by introducing transgenes that encode proteins involved in stress response pathways. This modifies how plants respond to environmental stresses, enabling them to maintain productivity under drought and nitrogen limitation conditions where conventional varieties would fail.
Solution Approach 2:
The patent creates composite genetic systems by combining multiple transgenes with different functions (e.g., stress-responsive promoters with drought-tolerance genes, nitrogen-use efficiency genes). This composite approach allows plants to simultaneously acquire multiple stress tolerance traits that work synergistically to maintain productivity under various stress conditions.
2Productivity
If resources are applied to enhance crop yields, then productivity increases, but resource utilization efficiency decreases
Solution Approach 1:
The patent introduces genes that enable plants to self-regulate resource acquisition and utilization. For example, enhanced root architecture genes allow plants to self-seeking nutrients and water more efficiently, while stress-responsive genes enable autonomous adaptation to resource-limited conditions, reducing the need for external resource inputs.
Solution Approach 2:
The patent modifies physiological parameters related to resource use efficiency, such as nitrogen assimilation rates, water use efficiency, and photosynthetic efficiency. These parameter changes allow plants to achieve higher yields with the same resource inputs, effectively converting resource consumption into productive output more efficiently.
