Double-stranded DNA amplifications were performed on50 l volume containing 2 mM of MgCl2, 200 mol/l of each dNTP,0.5 mol/l of each primer, 1 U of DNA polymerase (Biotools), and50 ng of DNA. The entire ITS region, comprising ITS1, 5.8 S gene andITS2, was amplified with external ITS1 and ITS4 universal primers(White et al., 1990). Standard PCR conditions were: preheating to94◦C for 5 min, 35 cycles of 1 min at 94◦C, 1 min at 54◦C, and 1 min30 s at 72◦C. For amplification and sequencing of the trnH-psbA andpsbJ-petA regions, the protocol of Shaw et al. (2005) and Shaw et al.(2007) were used. All amplification protocols finished with a finalextension of 72◦C for 10 min.
