For a number of reasons, the growth of bacteria is much more difficult to control in microgravity than it is on Earth. As a result, the high rate of infection blocked the vascular system of the plants. Bula states that this problem can be corrected, in part, by reducing the amount of bacteria since less is needed to do the job in microgravity. These results are the first steps leading to genetic engineered commercial products that will contribute to the economic competitiveness of U.S. industry. While cautioning that further experimentation is needed to verify the results and refine the methodology, Bula is excited by the results.
Work is already underway on a second gene transfer experiment.
This experiment will include refinements from the data gathered on STS-95, and instead of a marker gene will transfer a gene to the soybeans that has a medical application. Working through Commercial Space Centers that are funded by both NASA and Industry, companies can do research designed to produce the products and technologies of tomorrow. The research effort belongs to the industries involved, who are responsible for designing, funding, and analyzing the research. NASA, as its part of the partnership, provides access to microgravity for selected research.
