New Gene Transformation Method Developed
A research team and a bioengineering firm have jointly developed a new gene transformation method using acupuncture needles that is superior to existing techniques.
The team, led by Prof. Choi Yang-do of Seoul National University's college of agriculture and life science, announced yesterday that it has succeeded in developing an herbicide-resistant transgenic soybean jointly with Scigen Harvest Co.
The new method utilizes up to 30 bundled-up acupuncture needles to transplant a gene of interest into a target plant.
Choi said test results showed that the new technology has a much higher transformation success rate compared to existing technology.
He claimed that the newly developed technology has a success rate of up to 21 percent, much higher than the 0.5 percent of the current method.
``This implies that the cost and time of developing transgenic plants, a crucial factor for agricultural biotech companies, can be significantly reduced,'' Prof. Choi said.
The research team applied the technology to a currently cultivated soybean breed in an attempt to create a herbicide-resistant variant. …
