Figure 4.

RPB1 and RPB2 primers used in the study. The long bars show the extent of the coding regions of RPB1 and RPB2, while the boxes with letters or numbers in them represent the amino acid motifs that are conserved throughout the eukaryotes. The arrows above show the positions of the primers used in this study, and their amino acid sequences and degenerate oligonucleotide sequences are listed below.
