    Abstract: The present invention relates to inhibition of GTP cyclohydrolase II as target for the identification of fungicides. Binding assays are claimed and coupled enzymatic assays are disclosed involving the conversion of formate (product of the reaction catalyzed by GTP-cyclohydrolases) by formate dehydrogenase and spectroscopically measuring the NADH formed. Furthermore in vivo assays with organisms containing a GTP-cyclohydrolase II are claimed as well as a DNA sequence for a fungal GTP-cyclohydrolase II. 3-Butyl-10-(3-chlorophenyl)- 10H-pyrimido[4,5-b]quinoline-2,4-dione is identified by the enzymatic method as a fungicide. Finally, methods of controlling fungi (e.g. on plants, in soil) by applying this agent are claimed.

    Abstract: 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.
