Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for regulating gene expression in plants lack the ability to achieve unique and specific expression patterns in various tissues, limiting the precision and breadth of trait introduction through genetic engineering.
Innovation Solution
Development of hybrid regulatory elements combining segments from characterized regulatory elements to create novel polynucleotide sequences that drive unique tissue-specific or constitutive expression patterns in plants, allowing for the modulation of gene expression in specific tissues or broadly across plant tissues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional regulatory elements are used, then gene expression can be achieved, but unique and specific expression patterns in various tissues cannot be obtained
Solution Approach 1:
The patent divides regulatory elements into functional segments (promoter regions, enhancer regions, tissue-specific elements) that can be independently selected and combined. This segmentation allows researchers to mix and match segments to create hybrid regulatory elements with specific expression patterns for different tissues, thereby achieving versatility without excessive complexity.
Solution Approach 2:
The patent combines multiple regulatory element segments from different sources to create hybrid regulatory elements. By merging tissue-specific promoter segments with constitutive enhancer segments, the invention generates regulatory elements that achieve unique expression patterns not possible with conventional single-source regulatory elements.
2Adaptability or versatility
If tissue-preferred promoters are used, then expression in specific tissues is achieved, but broad expression across multiple tissues cannot be obtained
Solution Approach 1:
The patent creates hybrid regulatory elements that combine tissue-specific promoter segments with broad-spectrum enhancer segments. This multi-functional design allows the same regulatory element construction approach to achieve both tissue-specific expression and broad expression patterns depending on which segments are selected, providing universality in solving different expression needs.
3Manufacturing precision
If conventional regulatory elements are used, then gene expression can be achieved, but precise modulation of expression levels and locations cannot be accomplished
Solution Approach 1:
The patent applies local quality by selecting specific regulatory segments that confer particular functions (e.g., strong promoter segments for high expression, tissue-specific segments for location control). By locally optimizing the regulatory element composition with specific segments, the invention achieves precise control over expression levels and locations without requiring complete redesign of the entire regulatory structure.
