Objective A selection system is proposed for plant transformation that is exclusively based on genetic information already present in the host plant and not requiring anti-biotic resistance genes. Driving force for this approach is the public concern about a potential spread of antibiotic resistance genes in soil and intestinal bacteria possibly accentuated by the agricultural use of transgenic crops. The projects based upon truncated tubules lacking the binding site for carbonate herbicides. The expression of this truncated tubule is driven by the homologous tubule pro-motor within a DNA fragment devoid from exogenous sequences (minimal expression unit). The suitability of this selection system is demonstrated for rice as a model system for Graining crops Fields of science natural sciencesbiological sciencesmicrobiologybacteriologynatural sciencesbiological sciencesgeneticsDNAnatural scienceschemical sciencesinorganic chemistryinorganic compoundsmedical and health sciencesbasic medicinepharmacology and pharmacypharmaceutical drugsantibioticsmedical and health sciencesbasic medicinepharmacology and pharmacydrug resistanceantibiotic resistance Programme(s) FP5-LIFE QUALITY - Specific Programme for research, technological development and demonstration on "Quality of life and management of living resources", 1998-2002 Topic(s) 1.1.1.-3. - Key action The "Cell factory" Call for proposal Data not available Funding Scheme CSC - Cost-sharing contracts Coordinator ALBERT-LUDWIGS-UNIVERSITAET FREIBURG EU contribution No data Address Schaenzlestrasse 1 79104 FREIBURG (IN BREISGAU) Germany See on map Total cost No data Participants (2) Sort alphabetically Sort by EU Contribution Expand all Collapse all FRAUNHOFER IAF Germany EU contribution No data Address Tullastr. 72 79108 MÜNCHEN See on map Links Website Opens in new window Total cost No data NATIONAL RESEARCH COUNCIL OF ITALY Italy EU contribution No data Address Via E.Bassini 15 20133 MILANO See on map Total cost No data
