Figure 3From: Occurrence and characteristics of group 1 introns found at three different positions within the 28S ribosomal RNA gene of the dematiaceous Phialophora verrucosa: phylogenetic and secondary structural implicationsPhylogenetic tree of IC1 intron based on elements P, Q, R, S and a segment of P3. Numerals at each node are bootstrap probabilities from NJ analysis. Insertion positions are given after the sample ID or accession number. * indicates the insertion position relative to the 18S rDNA of the S. cerevisiae sequence.Back to article page
