Amplification of ITS Region
ITS sequences of nuclear ribosomal DNA were amplified using
primers [Table-2] of via the polymerase chain reaction (PCR) using
the AccuPower HF PCR PreMix (Bioneer, Daejeon, South Korea) in
20 μL volumes containing 2 μL of 10X buffer, 300 μM dNTPs, 1 μL
of a 10 pM solution of each primer, 1 unit of HF DNA polymerase.
One round of amplification consisting of initial denaturation, dena-
turation, annealing, and extension, and a final extension [Table-3].
The PCR products were purified with the SolGent PCR Purification
Kit-Ultra (SolGent, Daejeon, South Korea) prior to sequencing [Fig-
3].

DNA Sequencing
The purified fragments were directly sequenced using dye termina-
tor chemistry following the manufacturer’s protocol. The sequencing
reaction was performed in a 10 µl final volume with the BigDye
Terminator cycle sequencing kit (Perkin-Elmer, Applied Biosys-
tems). Cycle sequencing was conducted using same primers used
in amplification and BigDye vers. 3 reagents and an ABI PRISM
3100 DNA Analyzer (Perkin-Elmer, Applied Biosystems). Cycling
