- Abstract
Culture collections of microorganisms, including fungi, are strain deposits recognised as Biological Resource Centers (BRCs) with a great importance in science, industry and education. Their objective is to preserve the purity, viability and genomic integrity of every single strain as a member of such collection. Since improvement of molecular methods nowadays brought many novel approaches in manipulation with strains of microorganisms, they can also be useful for characterization of existing stored strains. ITS1 region in nuclear DNA is preferred barcoding marker for taxon identification, which can be explained by its great inter-species variability. This paper presents results from analysing ITS1 region sequences (17) obtained from fungal DNA of culture collection of autochthonous, lignicolous genera Piptoporus, Pleurotus, Ganoderma and Schizophyllum cultured on malt agar plates for 14 days at 25°C. BLAST (Basic Local Alignment Search Tool) was used for comparison with online databases, while alignment of sequences was made with MEGA 5.10 software. Morphological determination of species or genus was confirmed for 13 cultures, while the others were disproved. The resulting alignment indicated small intra-species variability of ITS1 region and pointed to it as an ideal marker for verification of fungal culture collections' authenticity.
