Revealing Mytilus galloprovincialis transcriptomic profile during ontogeny

ABSTRACT: Mediterranean mussels are a worldwide spread bivalve species with extraordinary biological success. One of the reasons of this success could be the reproduction strategy of bivalves, characterized by the presence of trochophore larvae. Larval development in bivalves has been a topic of raising interest in the scientific community but it deserves much more attention. The principal objective of this work was to study the transcriptomic profile of the ontogeny of M. galloprovincialis analyzing the gene expression in different developmental stages, from oocytes to seed. For this purpose, after conducting a 454 sequencing of transcriptome of mussel hemocytes, adult tissues and larvae, a new DNA microarray comprising sequences of was designed and developed. The studied developmental stages: unfertilized oocytes, veliger (3 days post fertilization; dpf) and pediveliger (20dpf) larvae, settled juveniles (25dpf) and seed (30dpf), showed very different transcriptomic profiles and clustered in groups defining their characteristic gene expression along ontogeny.
