Innovation Solution
Identification and isolation of new Solanum habrochaites nucleic acids encoding zingiberene synthases, which produce zingiberene, a natural insect repellent and insecticide, allowing for the generation of plants resistant to insect damage and the production of zingiberene for use in fragrances and repellent compositions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chemical pesticides and insecticides are used to control crop-destroying insects, then insect control effectiveness is improved, but toxicity and environmental incompatibility increase
Solution Approach 1:
The patent converts the harmful effect of synthetic chemicals into a beneficial natural alternative by utilizing zingiberene, a natural compound produced by plants. The invention transfers the insecticidal function from synthetic chemicals to a natural enzymatic process, thereby eliminating toxicity while maintaining insect control effectiveness through the synthesis and application of zingiberene-based insecticides
Solution Approach 2:
The patent introduces zingiberene as an intermediary substance between the plant and the insect. This natural compound serves as a mediator that provides insecticidal activity without the harmful properties of synthetic chemicals. The zingiberene synthase enzyme acts as a biological intermediary that produces this protective compound, replacing the need for toxic chemical intermediaries in the pest control process
2Reliability
If synthetic insecticides are used to protect crops, then crop protection is improved, but environmental sustainability deteriorates
Solution Approach 1:
The patent enables plants to protect themselves through self-service by utilizing their own metabolic pathways to synthesize zingiberene. The zingiberene synthase enzyme, which is naturally present in plants, converts farnesyl diphosphate into zingiberene, allowing the plant to produce its own insecticidal compound without external chemical intervention. This self-protection mechanism maintains environmental sustainability while ensuring continuous crop protection
Solution Approach 2:
The patent changes the chemical parameter of the insecticide from synthetic to natural origin. By modifying the source and composition of the insecticidal agent from petroleum-based chemicals to plant-derived zingiberene, the invention alters the environmental compatibility parameter while maintaining the protective function against insects
3Object-affected harmful factors
If natural insect repellents like zingiberene are used, then environmental compatibility is improved, but manufacturing efficiency deteriorates
Solution Approach 1:
The patent replaces mechanical/chemical extraction methods with a biological enzymatic system. Instead of mechanically extracting zingiberene from plant tissues or using chemical synthesis, the invention employs the zingiberene synthase enzyme to biologically produce the compound through a controlled biochemical reaction. This substitution of mechanical/chemical processes with enzymatic catalysis improves manufacturing efficiency while maintaining environmental compatibility
4Productivity
If zingiberene synthase enzymes are produced recombinantly, then manufacturing efficiency is improved, but process complexity increases
Solution Approach 1:
The patent segments the complex process of zingiberene production into distinct functional components: the zingiberene synthase enzyme, the substrate (farnesyl diphosphate), and the product (zingiberene). By isolating and optimizing each component separately, the invention simplifies the overall recombinant production process. The enzyme can be expressed in host cells, the substrate can be supplied independently, and the product can be extracted cleanly, thereby reducing process complexity while maintaining high manufacturing efficiency
