HPS1 Gene Regulation in Rice for Disease and Pest Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current chemical control methods for rice diseases and pests treat symptoms rather than the root cause, leading to drug resistance, environmental pollution, and ecological crises, while there is a lack of effective genetic solutions for enhancing plant resistance to biological stress.
Innovation Solution
Regulating and controlling plant disease and insect pest resistance by knocking out or overexpressing the HPS1 gene, utilizing its nucleotide and amino acid sequences (SEQ ID NO.1 and SEQ ID NO.2) to enhance resistance to fungal and bacterial diseases, and insect pests in rice.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chemical control methods are used to manage rice diseases and pests, then immediate symptom relief is achieved, but drug resistance develops and environmental pollution increases
Solution Approach 1:
The patent extracts and utilizes the natural resistance mechanisms inherent in rice plants through genetic modification. By knocking out the HPS1 gene or overexpressing resistance genes, the invention taps into the plant's own defense systems rather than relying on external chemical inputs, thereby eliminating drug resistance and pollution issues while maintaining control effectiveness
Solution Approach 2:
The invention enables rice plants to self-regulate their disease and pest resistance through genetic modification. The modified plants possess enhanced endogenous defense capabilities, allowing them to protect themselves against biological stresses without requiring external chemical interventions, thus solving the contradiction between immediate control and long-term harmful effects
2Reliability
If transcription factor genes are utilized to enhance plant resistance, then biological stress resistance is improved, but the functional understanding of these genes remains limited
Solution Approach 1:
The patent performs preliminary functional characterization of the HPS1 transcription factor gene before utilizing it for resistance enhancement. By systematically investigating the gene's function, expression patterns, and mechanism of action, the invention builds a comprehensive knowledge base that enables effective application while avoiding information loss about gene function
Solution Approach 2:
The patent employs feedback mechanisms through systematic functional analysis of the HPS1 gene. By continuously investigating and characterizing the gene's role in stress resistance, the invention refines understanding of transcription factor functions, using each experimental result to inform subsequent research and application strategies

AI summary
The disclosure relates to a method for regulating and controlling disease resistance in a rice plant by reducing disease resistance of the plant by knocking out the HPS1 gene or protein and/or improving disease resistance of the plant by overexpressing the HPS1 gene or protein. Compared with wild-type rice plants, rice overexpressing HPS1 gene has stronger resistance to different fungal or bacterial diseases, such as rice blast, sheath blight and bacterial blight, and has stronger resistance to insect pests caused by brown planthopper. The knockout of the HPS1 gene leads to a disruption in its protein-encoding ability, thereby causing the rice to exhibit weaker resistance to biological stress compared to wild-type rice.
