Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural practices lack effective compounds that can induce drought stress tolerance in plants, addressing the adverse effects of water scarcity on crop growth and yield.
Innovation Solution
The use of specific quinazolinones as phytoeffectors, including compounds such as Compound C123 (BER287) and Compound BER384 (QSP265, GOL102), which act by inhibiting plant PARP enzymes to enhance drought stress tolerance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If plants are exposed to drought stress conditions, then water availability is limited, but plant growth and yield are reduced
Solution Approach 1:
The patent applies parameter changes by modifying the chemical composition parameters of the plant through application of quinazolinone compounds. These compounds alter physiological parameters such as osmotic adjustment capacity, ROS detoxification enzymes, and stress hormone balances, enabling plants to maintain growth and yield despite limited water availability. The compounds change the plant's biochemical state to tolerate drought conditions.
2Reliability
If osmolyte accumulation is increased to maintain water potential, then water uptake is improved, but cellular metabolism may be negatively affected
Solution Approach 1:
The quinazolinone compounds act as intermediary substances that mediate between water stress conditions and cellular metabolism. They facilitate osmotic adjustment and enhance stress tolerance without directly disrupting metabolic pathways. The compounds serve as protective agents that allow the plant to maintain water potential while preserving cellular metabolic functions through mechanisms involving PARP enzyme inhibition and antioxidant systems.
3Object-affected harmful factors
If reactive oxygen species (ROS) are generated during water stress, then photosynthesis is disrupted, but plant stress response is activated
Solution Approach 1:
The patent converts the harmful effect of ROS generation during water stress into a beneficial stress response activation. The quinazolinone compounds inhibit PARP enzymes, which reduces ROS formation and enhances the plant's ability to manage oxidative stress. This transforms the harmful ROS accumulation into a controlled stress response that protects rather than damages the plant, improving photosynthesis efficiency under drought conditions.
