Solution Overview
Problem
Existing compositions fail to address the decrease in photosynthetic capacity caused by reactive oxygen species (ROS) in plants under abiotic stresses such as high or low temperature, salt, and drying conditions.
Innovation Solution
A composition comprising peptide-based and sugar-based biosurfactants, optionally with phospholipids and soybean meal degradation products, applied as a spray to plant leaves, which suppresses ROS generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plants are exposed to abiotic stresses (high temperature, low temperature, salt, drying), then environmental stress resistance is improved, but photosynthetic capacity decreases due to ROS generation
Solution Approach 1:
The patent applies biosurfactants to convert the harmful effect of ROS into a beneficial outcome. The biosurfactants reduce ROS generation in plants under stress, thereby protecting photosynthetic capacity while maintaining stress resistance. This transforms the harmful ROS pathway into a controlled process where the damage is mitigated by the surfactant intervention.
Solution Approach 2:
The biosurfactant acts as an intermediary substance between the plant and the environmental stress. It mediates the interaction by reducing ROS generation without eliminating the stress exposure, allowing the plant to maintain both stress resistance and photosynthetic function through the surfactant's protective role.
2Ease of operation
If conventional surfactants are used, then application ease is improved, but harmful effects on plants increase
Solution Approach 1:
The patent changes the chemical parameters of the surfactant from conventional synthetic types to biosurfactants with different molecular structures and properties. This parameter change results in reduced harmful effects on plants while maintaining the ease of application, as the biosurfactants are biocompatible and naturally derived.
Solution Approach 2:
The invention uses composite or mixed biosurfactant systems comprising different types (peptide-based, sugar-based, phospholipid-based) to achieve both ease of application and reduced harm. The composite nature allows optimization of both operational properties and plant compatibility.
