Fig. 1From: The diversity of mtDNA rns introns among strains of Ophiostoma piliferum, Ophiostoma pluriannulatum and related speciesSchematic diagram depicting the mtDNA rns gene and its introns insertion sites for Ophiostoma species. The diagram shows five insertion sites and the intron classes [Group I (GI) and Group II (GII)], intron types and the intron-encoded proteins are indicated (RT reverse transcriptase, LHE LAGLIDADG type endonuclease). The rns structural domains are indicated by Roman numbers (I–IV) (see Hafez et al. 2013). The red boxes represent GI introns and the blue boxes represent GII introns. Names surrounded by boxes drawn with dashed lines indicate the presence of degraded LHEs, whereas those in boxes with solid lines represent introns with intact LHEs. GenBank accession numbers are also indicatedBack to article page
