NUCLEOTIDE SEQUENCE CODING FOR AN ENZYME HAVING A ACETOLACTATE SYNTHASE ACTIVITY, PLANT CELL AND PLANT CONTAINING IT, AND METHOD FOR WEEDING PLANTS

摘要

The invention concerns a nucleotide sequence coding for an enzyme having a acetolactate synthase (ALS) activity, functional in the genus Cichorium, characterised in that said enzyme has reduced affinity for compounds of the sulphonyl urea or imidazolinone type. The invention also concerns an enzyme coded by this sequence, a plant cell or a plant containing them. The invention further concerns a method for detecting a plant with herbicide tolerance, and a method for weeding plants.
