Importance of organism and transcriptomesCrypthecodinium cohnii is a marine heterothrophic dinoflagellate for which several genetic, cytologic and molecular tools were developed, enabling the study of the unique features of the dinoflagellate cell. Culture synchronization and inducible sexual differentiation allows to provide a high range of RNA expression patterns; while functional tools can be developed to test the role of new identified RNA sequences. The evolution history and phylogenetic position of the species into the dinoflagellate group suggests that the endosymbiotic gene content of Crypthecodinium cohnii can provide a new picture of protist evolution especially for photosynthesis acquisition via secondary endosymbiosis and its subsequent loss.
