Trichoderma harzianum ThLml Inoculation for Crop Stress Tolerance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current agricultural practices face challenges in maintaining high crop yields due to abiotic stresses like drought, temperature extremes, and salinity, with no commercially available stress-tolerant crop plants or products capable of generating such crops through breeding or genetic modification.
Innovation Solution
Inoculation of plants with the isolated Trichoderma harzianum strain ThLml, deposited under NRRL 50846, or its asexual progeny/spores, which promotes stress tolerance, enhances growth, and increases germination, thereby improving plant health and yield under stressful conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional agricultural practices are used, then crop production continues, but crop yields decrease due to abiotic stresses like drought, temperature extremes, and salinity
Solution Approach 1:
The patent applies preliminary action by inoculating plant seeds with Trichoderma harzianum ThLml fungus before planting, allowing the fungus to establish a protective symbiotic relationship with the plant before abiotic stresses occur. This pre-colonization enables the plant to have enhanced stress tolerance mechanisms already in place when drought, temperature extremes, or salinity conditions arise, thereby maintaining crop yields under stressful conditions
2Reliability
If breeding or genetic modification approaches are used, then stress-tolerant crops could be developed, but no commercially available products currently exist capable of generating such crops
Solution Approach 1:
The patent uses Trichoderma harzianum ThLml fungus as an intermediary organism that mediates stress tolerance in plants without requiring direct genetic modification of the crop plants themselves. The fungus acts as a biological mediator that colonizes plant roots and provides protective effects against abiotic stresses, offering a commercially viable alternative to breeding or GM approaches while achieving reliable stress tolerance
3Productivity
If water consumption is reduced through inoculation, then plant growth is enhanced, but resource allocation requires optimization
Solution Approach 1:
The patent applies parameter changes by altering the plant's physiological parameters through fungal inoculation. The Trichoderma harzianum ThLml fungus changes the plant's water use efficiency parameter, enabling the plant to maintain enhanced growth and photosynthetic activity while consuming less water. This parameter transformation allows the plant to achieve better productivity with reduced resource input
