Abstract (en)

[origin: WO0204619A2] The invention relates to the use of a nucleic acid sequence coding for a polypeptide exhibiting dehydroquinate dehydrase/shikimate dehydrogenase activity for producing a test system for discovering the inhibitors of dehydroquinate dehydrase/shikimate dehydrogenase. For the first time, it has been shown, with the aid of the antisense technology, that dehydroquinate dehydrase/shikimate dehydrogenase constitutes a herbicide target. The invention further relates to a method for producing transgenic plants containing a nucleic acid sequence coding for a polypeptide containing dehydroquinate dehydrase/shikimate dehydrogenase (E.C. 4.2.1.10/E.C. 1.1.1.25) activity, characterised by an increased biomass production or/and an increased content of aromatized amino acids compared to a non-transgenic plant.
