Abstract:A specific marking and detection technique is a fundamental requirement for the safer use of genetically modified (GM) organisms. Here we propose a simple and effective method for directly marking functional transgenes in GM organisms. For that purpose, we introduced nucleotide substitutions (NS), based on the degeneracy of codons as markers (NS markers), into the bphC (2,3-dihydroxybiphenyl dioxygenase) and tomA3 (toluene-ortho-monooxygenase) gene frames using a PCR-based method. No change was observed in the… Show more
