Fig. 2From: Mobile group I introns at nuclear rDNA position L2066 harbor sense and antisense homing endonuclease genes intervened by spliceosomal intronsMolecular phylogeny of myxomycete and ascomycete L2066 group I introns. The intron topology was obtained by Neighbor-joining (NJ) analysis of 34 taxa and 186 nt aligned positions. The Didymium iridis intron Dir.S956–1 was included as an outgroup. The NJ and Minimal Evolution (ME) bootstrap replicates (≥ 50%) are given for each node (NJ/ME). Maximum support in NJ and ME (≥ 97%) are shown in bold branches. Black dots at branch points indicate NJ and ME robustness (≥ 90%). The scale-bar indicates the fraction of substitutions per site. GenBank accession numbers for taxa are shownBack to article page
