Emiliania huxleyi is one of the most abundant phytoplankton species in the ocean playing an important role in global carbon fluxes and represents haptophytes an enigmatic group of unicellular organisms that diverged early in eukaryotic evolution. This species is haplo-diplontic. Little is known about the haploid cells but they have been hypothesized to allow persistence of the species between the yearly blooms of diploid cells. We sequenced over 38 000 expressed sequence tags from .
