Transcriptome sequencing of cochleae from constant-frequency and frequency-modulated echolocating bats

Echolocating bats are fascinating for their ability to ‘see’ the world in the darkness. Ultrahigh frequency hearing is essential for echolocation. In this study we collected cochlear tissues from constant-frequency (CF) bats (two subspecies of Rhinolophus affinis, Rhinolophidae) and frequency-modulated (FM) bats (Myotis ricketti, Vespertilionidae) and applied PacBio single-molecule real-time isoform sequencing (Iso-seq) technology to generate the full-length (FL) transcriptomes for the three taxa. In total of 10103, 9676 and 10504 non-redundant FL transcripts for R. a. hainanus, R. a. himalayanus and Myotis ricketti were obtained respectively. These data present a comprehensive list of transcripts involved in ultrahigh frequency hearing of echolocating bats including 26342 FL transcripts, 24833 of which are annotated by public databases. No further comparative analyses were performed on the current data in this study. This data can be reused to quantify gene or transcript expression, assess the level of alternative splicing, identify novel transcripts and improve genome annotation of bat species.
