In 2016 A. tumefaciens containing the BBa_ K1800002 in the pORE vector was grown in YEP medium for 16 hours at 25 Celsius. The bacteria culture was pelleted by spinning at for 10 minutes. The supernatant was poured off, and the pellet resuspended in nitrogen-free plant nutrient medium until the final value of 0.2 was achieved. Rock wool plugs, about 0.5 inches thick, were inoculated with 5mL of solution containing the resuspended pellet of A. tumefaciens was added to a hole in the wool. Now into the hole made in the wool a 3 cm stem from the sterile tobacco plants was placed, and the wool placed into petri dishes which were then placed into a clear storage container. The container is then covered with a lid and the container sat under ambient light at 25 Celsuis for 5 days under ambient light in the flow hood. After dehydration treatment, the plugs are saturated with deionized water, and the cover of the container replaced. The plugs were then checked periodically and watered when necessary for the remainder of the induction period. After two to three weeks’ hairy roots grew out of the rock wool. The hairy roots contain the horseradish peroxidase gene. See the figure below.
