Comprehensive analysis of Metacrinus rotundus full length transcriptome.

ABSTRACT: Modern stalked crinoids, an important group of echinoderms, represent the ancestral mode of crinoids, and studying their evolution is key to understanding the evolution of echinoderms. In this study, we selected Metacrinus rotundus, a species of modern stalked crinoids, for investigation. We generated M. rotundus transcripts using Pacific Biosciences single-molecule real-time (SMRT) long-read sequencing technology. A total of 160,849 full-length (FL) transcripts were captured by Iso-Seq, with a mean length of 2,470 bp. Of these FL transcripts, 110,859 were well-annotated based on public database. A portion of transcripts remained unannotated, representing potential novel genes for M. rotundus. Additionally, we identified 71,740 long-noncoding RNA (LncRNAs), 57,548 simple sequence repeats (
