Abstract Details

2011, Master of Science (MS), Bowling Green State University, Biological Sciences.
Group I introns are self-splicing, ancient and abundant, being distributed sporadically among many phylogenetic lineages. This study is the first to report group I intron elements in the rDNA spacer regions (ITS1 and ITS2) of any organism and is the first report in any metazoan spacer region. Putative group I introns have been identified in ITS1 and ITS2 regions of all eight extant orders of sharks that are included in this study. The secondary structure prediction and analysis of these putative group I introns reveal that the introns have maintained all of the regions found in functional introns and thus are probably group I introns capable of splicing. Phylogenetic analysis indicates that these introns horizontally transferred prior to the evolution of all Orders of the Chondrichthyes, appearing first in ITS1 region. Since their first appearance, they have been evolving in parallel with shark species.
