Title: Inventor Yin-Fu Chang: Pioneering Plant Transformation Methods

Introduction

Yin-Fu Chang is a renowned inventor based in Carrboro, NC, specializing in innovative methods of plant transformation. With a notable portfolio of nine patents, Chang's contributions to the field of biotechnology have paved the way for advancements in the production of transgenic plants.

Latest Patents

Chang's latest patents focus on two significant methods aimed at enhancing plant transformation. The first patent describes an enhanced method of producing transgenic plants by utilizing a wounded transformable explant, which includes a hypocotyl, at least one cotyledon, and wounded tissue. The innovative process involves transforming cells in the explant and subsequently transferring it to a growing medium containing selection compounds for a selectable marker. This breakthrough contributes to the production of transgenic plants that exhibit desirable traits.

The second patent introduces methods for stable transformation of plants by inducing multiple shoot structures from plant tissues, such as shoot apices or axillary buds, on an artificial medium. These structures can then be transformed using known transformation techniques, allowing for the regeneration of plants from transformed cells. This method is particularly effective for crops that are generally difficult to transform, including sugar beet, sunflower, soybean, cotton, tobacco, tomato, peanuts, melons, watermelon, squash, and pepper.
