This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,598.

Summary of the Inventive Concept

This inventive concept leverages the core technology of self-replicating cell selective gene delivery to address pressing challenges in agriculture, enabling targeted gene delivery to specific cell populations in plants and microorganisms for improved crop yields, reduced pesticide use, and environmental remediation.

Background and Problem Solved

The original patent disclosed self-replicating cell selective gene delivery compositions for therapeutic applications. However, the agricultural industry faces significant challenges in crop yield, pest resistance, and environmental sustainability. This inventive concept adapts the core technology to address these problems, providing a novel solution for the agricultural sector.

Detailed Description of the Inventive Concept

The inventive concept comprises self-replicating cell selective gene delivery compositions and methods for introducing these compositions into plant cells or microorganisms. The compositions include RNA molecules of interest encoding proteins involved in plant growth regulation, pest resistance, or pollutant degradation. The system can be used to improve crop yields, reduce pesticide use, and create genetically modified organisms for environmental remediation. The device for monitoring plant health uses sensors to detect the presence of the self-replicating cell selective gene delivery composition in plant cells, providing an output indicative of plant health.

Novelty and Inventive Step

The new claims introduce the application of self-replicating cell selective gene delivery to the agricultural industry, which is a non-obvious and novel extension of the original patent's therapeutic focus. The inventive concept's ability to target specific cell populations in plants and microorganisms, and its potential to improve crop yields, reduce pesticide use, and enable environmental remediation, demonstrate a significant inventive step beyond the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different viral replicases, modifications to the RNA molecule of interest, or the incorporation of additional components to enhance gene delivery efficiency. Variations of the system could be designed for specific crop types, pest resistance, or environmental remediation applications.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in the agricultural industry, with potential applications in crop improvement, pest management, and environmental sustainability. The market for agricultural biotechnology is growing rapidly, and this inventive concept could provide a competitive advantage for companies operating in this space.
