Abstract
Data obtained from genomic fingerprinting were used to perform hierarchical cluster analysis and demonstrated ability to differentiate strains at intra-specific level. However, the high level of variability prevents their use as an identification tool. ITS amplification displayed intra-specific polymorphism both in number and length of the obtained amplicons, but revealed itself as a good method for strain clustering. The unsuccessful amplification of peptide synthetase (PS) and polyketide synthase (PKS) genes pointed to the inability of Portuguese C. raciborskii strains to produce cylindrospermopsin. HPLC analysis further confirmed this lack of toxicity, since negative results were obtained for cylindrospermopsin and PSP toxins.
