Tracking Plant Microbes with Their Natural DNA Barcodes
This patent describes a method to track how microbes colonize plant roots by using and reconfiguring their naturally occurring DNA sequences as unique tags.
Original patent title: “Plant colonization assays using natural microbial barcodes”
This patent describes a method to track how microbes colonize plant roots by using and reconfiguring their naturally occurring DNA sequences as unique tags. Granted in 2026.
Coverage
What does this patent actually cover?
The patent details methods for tracking microbial colonization on plant root systems. It uses specific DNA sequences, called "nucleic acid barcodes," which naturally exist in microbial cells, along with nearby "amplifying sites." These natural genetic elements are then reconfigured into a single, easy-to-use "nucleic acid cassette." This cassette allows researchers to tag different microbial species, strains, or variants, each with a unique barcode. By tracking these barcoded cells, the patent enables assays to measure the relative ability of different microbes to colonize a plant root system. For example, scientists could tag different beneficial bacteria and see which ones are best at attaching to and growing on corn roots.
The gap
What does this patent NOT cover?
- Does not cover tracking microbial colonization in animals or humans, as the focus is specifically on "plant root systems."
- Does not cover using entirely synthetic or artificially engineered barcodes that do not naturally occur within the microbial cells.
- Does not cover tracking microbes on other parts of a plant, such as leaves, stems, or flowers, as the abstractabstractA short summary at the front of the patent describing the invention. Not legally binding.Read more → specifies "plant root system."
- Does not cover methods that measure the absolute quantity of microbial colonization, but rather focuses on "relative microbial colonization ability."
- Does not cover tagging methods that rely on non-nucleic acid components, such as protein markers or fluorescent dyes.
These exclusions are unique to PatentBrief — derived from the actual claim language, not patent-office boilerplate.
Key facts
What made this novel
The clever part is using DNA sequences that already exist naturally within the microbes, along with their natural amplifying sites. By reconfiguring these into a single cassette, the method avoids introducing entirely foreign genetic material, making the tagging process potentially more natural and less disruptive to the microbes.
