Abstract (EN): <jats:title>Abstract</jats:title><jats:p><jats:italic>Paracentrotus lividus</jats:italic> is the most abundant, distributed and desirable echinoid species in Europe. Although, economically important, this species has scarce genomic resources available. Here, we produced and comprehensively characterized the male and female gonad transcriptome of <jats:italic>P. lividus</jats:italic>. The <jats:italic>P. lividus</jats:italic> transcriptome assembly has 53,865 transcripts, an N50 transcript length of 1,842 bp and an estimated gene completeness of 97.4% and 95.6% in Eukaryota and Metazoa BUSCO databases, respectively. Differential gene expression analyses yielded a total of 3371 and 3351 up regulated genes in <jats:italic>P. lividus</jats:italic> male and female gonad tissues, respectively. Additionally, we analysed and validated a catalogue of pivotal transcripts involved in sexual development and determination (206 transcripts) as well as in biosynthesis and storage of lipids (119 transcripts) in male and female specimens. This study provides a valuable transcriptomic resource and will contribute for the future conservation of the species as well as the exploitation in aquaculture settings.</jats:p><jats:sec><jats:title>Highlights</jats:title><jats:p>Assembly of a reference transcriptome of <jats:italic>Paracentrotus lividus</jats:italic> gonads.</jats:p><jats:p>Differential gene expression between males and female gonads of <jats:italic>Paracentrotus lividus.</jats:italic></jats:p><jats:p>Identification and validation of pivotal genes involved in biosynthesis and storage of lipids.</jats:p></jats:sec>
