DRO1 Gene Editing for Root Architecture and Yield
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for improving crop yields are limited by the capacity of plants to absorb water and nutrients, and there is a need for more effective strategies to modify root architecture for enhanced nutrient and water acquisition.
Innovation Solution
The use of CRISPR-Cas associated editing systems to introduce mutations in the DEEPER ROOTING 1 (DRO1) gene, which encodes a polypeptide involved in root architecture modification, to enhance root growth and nutrient uptake in plants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional breeding methods are used to improve root architecture, then some yield improvement is achieved, but the capacity to absorb water and nutrients remains limited
Solution Approach 1:
The patent applies parameter changes by modifying the DRO1 gene sequence to create variants with altered functionality. Specifically, the invention changes amino acid residues in the DRO1 polypeptide (such as substituting hydrophobic residues with polar or charged residues) to enhance the protein's ability to promote root architecture development, thereby improving water and nutrient absorption capacity beyond what conventional breeding achieves.
Solution Approach 2:
The patent replaces mechanical/conventional breeding methods with genetic engineering approaches. Instead of relying on natural variation and traditional selection, the invention uses precise molecular modification of the DRO1 gene to directly achieve desired root architecture traits, enabling more effective improvement of water and nutrient uptake capacity.
2Quantity of substance
If the DRO1 gene is modified to enhance root architecture, then water and nutrient absorption is improved, but the complexity of the genetic modification process increases
Solution Approach 1:
The patent applies segmentation by dividing the DRO1 gene into functional domains and modifying specific regions independently. The invention focuses on particular amino acid positions (such as residues 1-200, or specific transmembrane domains) to achieve the desired effect, rather than attempting to redesign the entire gene, thereby reducing modification complexity.
Solution Approach 2:
The patent applies local quality by making targeted modifications at specific locations within the DRO1 gene sequence. The invention substitutes amino acids at particular positions (such as hydrophobic to polar substitutions in transmembrane domains) while leaving the rest of the protein structure intact, enabling precise control over root architecture enhancement without unnecessary complexity.
