A screening of PGU genes of ascomycetous yeasts deposited in the GenBank (http: //www.ncbi.nlm.nih. Gov/genbank/) and Sanger Institute databases ( has been performed using the nucleotide sequence of the PGU1 gene of S. cerevisiae S288c as a query. Divergent pectinase genes were found out in the Eremothecium, Galactomyces, Geotrichum, Kluyveromyces and Lachancea genera. Within the genera, the following similarity of the PGU nucleotide sequences was observed: 64,5-982% for Kluyveromyces, 72,7-81,3% for Galactomyces/Geotrichum, and 69-87,9% for Eremothecium. Polymeric PGU genes capable of interspecies transferring were documented in Galactomyces citri-aurantii, Galactomyces candidus and Geotrichum klebahnii. The importance of the PGU genes for the diagnosis and selection of yeasts is discussed.
