Dyella-like Bacterium Composition for Phytoplasma Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for controlling phloem-restricted pathogens like phytoplasma in grapevines are inefficient, and there is a need for new strategies to manage diseases that affect wine quality and grape production.
Innovation Solution
An isolated bacterium with specific nucleic acid sequences, referred to as the Dyella-like bacterium, is used in compositions that include emulsifiers and growth substrates, which exhibit anti-pathogenic activity against phytopathogens, including phytoplasma, by reducing symptoms and penetrating plant tissues through roots, seeds, and leaves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional pesticides are used to control phytoplasma, then disease control is attempted, but the control is inefficient and wine quality consistency deteriorates
Solution Approach 1:
The patent introduces a bacterial endophyte as an intermediary organism that colonizes plant tissues and produces antimicrobial compounds. This endophyte acts as a mediator between the plant and phytoplasma pathogen, providing protection through natural biological mechanisms rather than direct chemical intervention, thereby maintaining wine quality while controlling disease
Solution Approach 2:
The patent replaces the mechanical/chemical system of conventional pesticide application with a biological system using endophytic bacteria. The biological control mechanism involves the endophyte colonizing plant tissues and producing antimicrobial substances naturally, substituting the need for external chemical pesticides and their associated quality impacts
2Reliability
If new biological control strategies are developed, then disease control effectiveness improves, but the complexity of the control system increases
Solution Approach 1:
The patent employs self-service principles where the endophytic bacteria autonomously colonize plant tissues and produce antimicrobial compounds without requiring complex external management. The biological control system serves itself by utilizing the endophyte's natural abilities to establish protection, reducing the need for complex application and monitoring systems
