In order to construct specific primers for the detection and identification of the entomopathogenic fungus Metarhizium within infected sugarcane borer (Diatraea saccharalis) larvae we analyzed the ITS1 -5.8S- ITS2 rDNA regions of strains and varieties of M. anisopliae, M. album and M. flavoviride. The PCR amplification of these regions yielded a unique fragment of approximately 540 bp for M. anisopliae variety anisopliae strains E9, B/Vi and C (isolated in Brazil), 600 pb for M. a. anisopliae strain 14 (isolated in Australia), 650 bp for the M. album and 600 bp for M. flavoviride strains. The PCR products were digested with different restriction endonucleases (Afa I, Alu I, Dde I, Hae III, Hpa II and Sau 3A) and the PCR-RFLP profiles showed clear...

Preliminary notes on dual relevance of ITS sequences and pigments in Hygrocybe taxonomy .

The relationships based on ITS sequences of 48 Hygrocybe s.l. specimens were studied and compared with previously described taxonomic groups. Our specimens formed two well separated genetic groups. The first one includes the species characterized by vivid yellow and red colours, while species belonging to other clades were pallid or pale brown, and in most cases with pink or olive tones. This separation is supported by the presence of muscaflavin pigments among some species referred to Hygrocybe (Bresinsky &amp; Kronawitter 1986). The subgenera distinguished by morphological features can be relatively well recognized on phylogenetic trees, however, the majority of sections were not supported. Variability in the ITS region of Hygrocybe species is unusually...
