Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current maize varieties have relatively low protein content, which fails to meet the nutritional demands of animals and requires additional protein supplementation, such as soybean imports, and there is a need for genetic resources to enhance maize quality and protein content.
Innovation Solution
The application of the Zm00001d030087 gene, which is associated with kernel protein content, is utilized to regulate protein levels in maize through overexpression or silencing, enabling the development of maize varieties with high or low protein content as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional maize varieties are used, then current agricultural practices are simple and cost-effective, but the protein content is low and fails to meet nutritional demands
Solution Approach 1:
The patent applies parameter changes by modifying the expression level of the Zm00001d030087 gene to directly alter the protein content parameter in maize kernels. Through overexpression or silencing of this specific gene, the invention achieves significant changes in protein quantity without fundamentally changing the overall breeding system complexity.
Solution Approach 2:
The invention extracts the specific functional gene Zm00001d030087 from the complex genetic system of maize and isolates its effect on protein content. By focusing on this single gene's manipulation, the patent simplifies the breeding approach while achieving the desired improvement in protein content, rather than attempting to modify multiple genetic factors simultaneously.
2Quantity of substance
If additional high protein products like soybean are added to compensate for low maize protein, then nutritional demands are met, but dependency on soybean imports increases and costs increase
Solution Approach 1:
The patent makes maize serve multiple functions by enhancing its protein content to levels that can partially replace soybean's nutritional role. By improving maize's protein quality and quantity through gene manipulation, the invention allows maize to function not only as a staple carbohydrate source but also as a significant protein source, reducing the need for additional protein supplements.
Solution Approach 2:
The invention converts the previously harmful effect of low protein content (which necessitated soybean imports) into a benefit by using modern biotechnology to enhance protein content. The same genetic manipulation tools that could be seen as increasing complexity are transformed into a solution that eliminates the need for soybean imports and improves nutritional self-sufficiency.
3Quantity of substance
If maize quality is enhanced to meet increasing nutritional demands, then nutritive values improve, but breeding difficulty and technical requirements increase
Solution Approach 1:
The patent simplifies the breeding process for quality enhancement by changing the approach from traditional multi-gene selection to targeted manipulation of a single key parameter - the expression level of Zm00001d030087 gene. This focused parameter change makes breeding easier despite the goal of improving quality, as it requires monitoring and manipulating fewer genetic factors.
Solution Approach 2:
The invention introduces molecular markers as intermediaries that simplify the breeding process. These markers serve as proxies for the Zm00001d030087 gene's expression state, allowing breeders to select for high or low protein content phenotypes without directly measuring protein levels in each generation. This intermediary approach significantly eases the breeding process while achieving quality enhancement.
