Evidence for the Transcription of a Satellite DNA Widely Found in Frogs.

ABSTRACT:

Background

The satellite DNA (satDNA) PcP190 has been identified in multiple frog species from seven phylogenetically distant families within Hyloidea, indicating its broad distribution. This satDNA consists of repeats of approximately 190 bp and exhibits a highly conserved region (CR) of 120 bp, which is similar to the transcribed region of 5S ribosomal DNA (rDNA), and a hypervariable region (HR) that varies in size and nucleotide composition among and within species. Here, to improve our understanding of PcP190 satDNA, we searched for evidence of its transcription in the available transcriptomes of Rhinella marina (Bufonidae) and Engystomops pustulosus (Leptodactylidae), two phylogenetically distantly related species.

Methods

We first characterized the 5S rDN
