NTS class I and NTS class II nucleotide sequences from the stingray species included in this study. a) Nucleotide sequence alignment of short NTS repetitions of class I; (b) partial nucleotide sequence alignments of long NTS repetitions of class II obtained from the stingrays genome. Species are referred to as follows: Pfalkneri = Potamotrygon falkneri, Pmotoro = P. motoro, Paireba = Paratrygon aiereba. Dots represent conserved nucleotides and hyphens report indels. The microrepetition TCCC expanded in the P. aiereba genome is indicated in gray shading. Dots represent conserved bases and hyphens report indels.
