Abstract

Graphic abstract

Perumytilus purpuratus is a marine mussel considered a bioengineer species with a broad distribution in the Pacific and Atlantic coast of South America. Studies have shown two geographically and genetically differentiated subpopulations at molecular level and in sperm morphological traits. To open avenues for molecular research on P. purpuratus, a global de novo transcriptome from gonadal tissue of mature males was sequenced using the Illumina platform. From a total of 126.38 million reads, 37,765 transcripts were successfully annotated. BUSCO analysis determined a level of 89% completeness for the assembled transcriptome. The functional gene ontology (GO) annotation indicated that, in terms of abundance, the transcripts related with molecular function were the most represented, followed by those related with biological process and cellular components. Additionally, a subset of GO annotations generated using the “sperm” term resulted in a total of 1,294 sequences where the biological process category was the more represented, with transcripts strongly associated to sperm-processes required for fertilization, and with processes where the sperm-egg interaction could be implicated.

Our work will contribute to the evolutionary understanding of the molecular mechanisms related to tissue-specific functions. This work reports the first male gonad transcriptome for the mussel P. purpuratus, generating a useful transcriptomic resource for this species and other closely related mytilids.
