PCR products with ITS primers were digested with the restriction
enzymes EcoRI and SmaI (MBI; Fermentas) as described in Diguta
et al. (2011). The restriction enzymes were selected after ITS
sequence analysis in the Serial Cloner software, allowing
differentiation among fungal species. The digestions were
performed overnight following the manufacturer's instructions.
RFLP analyses were done in 2% agarose gel and the sizes of each
fragment were estimated by comparison with DNA ladder (100 bp
DNA marker, Gene Ruler) and the computer program of Photocapt
MW software 10.0, Vilber Lourmat.
