Importance of organism and transcriptomesOxyrrhis marina represent a unique lineage making it of high interest for a transcriptome study. 1) It represents the most ancient (basal) lineage of common dinoflagellates, and its transcriptome sequences will allow investigation of evolution of molecular machines in the phylum of dinoflagellates; 2) this species is heterotrophic, an important micrograzer in the marine food web. Transcriptome studies will allow search for genes involved in grazing; 3) little work has been done to transcriptomes in heterotrophic dinoflagellates because of inevitable contamination by prey RNA. It is no longer a problem due to the discovery of the specific spliced leader in dinoflagellate mRNA sequences (Zhang et al. 2007 PNAS 104: 4618-4623). Finally transcriptimic data from O. marina will be very useful in studying the radiation of dinoflagellates.
