Importance of organism and transcriptomesForaminifera are among the most abundant and diverse marine protists, characterized by granuloreticulopodia. Their tests or shells are an important component of marine sediments and widely used as biostratigraphic markers. Ammonia sp. is classified with the order Rotaliida for which no published EST exists up to date. The genus is common in the coastal waters and our strain was collected from the North Sea. To date, the molecular data on this organism, and foraminifers in general, is extremely poor represented in the available databases. Our knowledge on the gene expression repertoire and metabolic pathways used by foraminifers is still very limited. Additionally, transcriptomic data has shown to be a powerful tool for finding orthologous genes for further phylogenetic analysis, in an aim to resolve the phylogenetic relationships among the group and within the Eukaryotes.
