ABSTRACT



In the present work we focused on the comparison of genome diversity of 23 strains of Geotrichum candidum isolated from different sources. The analysis of restriction fragment length polymorphism after amplification of rDNA cluster with NS3-ITS4 primers (RFLP-PCR rDNA) and randomly amplified polymorphic DNA (RAPD) analysis with four primers [(GTG)5, (GAC)5, (GACA)4 and M13] were applied for scanning the genome. In RFLP-PCR rDNA with Msp I the physiological classification at species level was confirmed, however two types of pattern were obtained with Hae III. The diversity among some strains was observed in RAPD. Microsatellite primer (GACA)4 was the most discriminating one, only one species specific product was observed. For 20 strains, primer (GTG)5 gave very similar pattern (>80%) allowing the determination of three species specific products (920, 720 and 510 bp). Species specific products were also found with (GAC)5 and M13 primers. The microsatellite overall dendrogram allowed the individual recognition of five strains of G. candidum, for which the patterns similarity was <70%. RAPD patterns similarity of 80% or more, obtained for the rest of strains, reflected rather low genome diversity of G. candidum.

Key words: Geotrichum candidum, RFLP-PCR, RAPD-PCR.
