Latest Patents

One of his latest patents is titled "Methods and compositions for the production of stably transformed, fertile monocot plants and cells thereof." This invention focuses on a reproducible system for producing stable, genetically transformed maize cells. It includes methods for selecting transformed cells using the bar gene, which is introduced into embryogenic maize cells through microprojectile bombardment. The cells are then grown in suspension cultures and exposed to the herbicide bialaphos. The patent also covers tissue culture methods, media, and the growth of fertile plants from the transformed cells. Another notable patent is the "Method for plant breeding," which relates to glyphosate-resistant maize plants, including transformation events such as GA21, GG25, GJ11, and FI117. This invention outlines methods for using herbicide resistance in plant breeding and ensuring seed purity.
