Schematic representation of part of the rDNA transcriptional unit and relative locations of primers (Tricho-F, Tricho-R and JhTsp) used in this study. The region harboring 5.8S and internal transcribed spacer 2 region (ITS2) rDNA was amplified with Tricho-F and Tricho-R by real-time polymerase chain reaction and with JhTsp and Tricho-R for DNA sequencing.
