The investigations carried out in the Institute of Industrial Organic Chemistry on sulphur fungicides are discussed and some neu investigation possibilities are presented. Elementary sulphur - one of the oldest known fungicide is still being used in plant protection, mostly against powdery mildews in orchard, vegetables, ornamental and cereal crops. Because it is of low toxicity to mammals and aqueous organisms, and does not disturbance the environment it is now respected as one of the "ecological fungicide". In contrasts to the modern, highly selective, systemic fungicides sulphur does not provoke the resistance building in plant pathogenic fungi, what is profitable in its usage as component of fungicidal mixtures.

The most abundant lesion formed in DNA upon modification with methylating agents 7-methylguanine, under alkaline conditions is converted into 2,6-diamino-4-hydroxy-5N-methyl-formamidopyrimidine (Fapy-7MeGua). We have previously shown that treatment of dimethylsulfate methylated DNA with NaOH creates mutagenic base derivatives leading to a 60-fold increase in the frequency of A-->G transitions and a 2-3-fold increase of G-->T and G-->C transversions. We have analyzed which lesions lead to these mutations. We compared mutagenic spectra in the lacZ gene of M13mp18 phage DNA modified with dimethylsulfate and NaOH after selective elimination of damaged bases from molecules used for transfection into SOS-induced E. coli. Partial elimination of Fapy-7MeGua from phage DNA performed by its digestion with formamidopyrimidine-DNA glycosylase resulted in a 2-3-fold decrease of G-->T and G-->C transversions. Selective depurination of methylated bases (9 h, 37°C, pH 7,0) resulting in almost complete loss of 7MeAde as demonstrated by HPLC analysis of (3H)MNU alkylated phage DNA used as a probe, caused a dramatic, 9-fold decrease of A-->G transitions. Alkali-catalysed rearrangement of 7MeAde was followed by HPLC analysis of (3H)MNU alkylated polyA and polydA. After incubation of these oligonucleotides in NaOH, 7MeAde disappeared from both chromatograms, but only in polyA, 2 new peaks migrating with retention time different from that of 1MeAde, 3MeAde or 7MeAde were detected, suggesting formation of two rotameric forms of Fapy-7MeAde as observed for Fapy-7MeGua. Thus the miscoding lesion, giving rise to A-->G transitions derived from 7MeAde was Fapy-7MeAde. Fapy-7MeGua was at least an order of magnitude less mutagenic, but in SOS-induced cells it gave rise to G-->T and G-->C transversions.
