RNA-seq data from mature male gonads of marine mussels Mytilus edulis and M. galloprovincialis

Abstract The mussels Mytilusedulis and Mytilusgalloprovincialis are marine organisms with external fertilizationable to hybridize where their distributions overlap allowing the study of reproductive isolationmechanisms in nature. We provide raw dataof a transcriptomic analysis of mature male gonads from these two Mytilusspp. using NGS (Illumina) technology and a preliminary list of transcript that were functionally annotated showing species-specific differential expression. A shortlist including some of these genes and their corresponding proteins have been thoroughly analysed and discussed in Romero et al. (2018, Submitted for publication).
