First North announcement # 7, 2008 Copenhagen, March 31, 2008 The RedDetect® technology is successfully transferred into tobacco The RedDetect® technology has successfully been transferred into tobacco, which is considered more robust than the original host plant, Thale cress (Arabidopsis thaliana). Hence the company has been able to produce several lines of transgenic tobacco plants, which will be sown at the test site in Novi Sad, Serbia during the summer, according to the plans. The objective is to confirm the color change of RedDetect® in tobacco after growth in soil contaminated with explosives under realistic conditions in terms of climate and soil. ”We are very satisfied that we have been able to transfer this complex technology in relatively short time”, Carsten Meier, CSO at Aresa, says. ”It has taken us nine months to come to this point with the tobacco plant, and it is a very important milestone we have reached”. “The successful transfer of the technology into tobacco is a result of the strategy focusing the research and development resources entirely to the landmine plant”, Steen Thaarup, CEO, says. “Other resources are focused at the operational activities in relation to landmine clearing in the Balkan region”.
