Importance of organism and transcriptomesLeptocylindrus danicus var. danicus is a centric colonial diatom branching off deep in the phylogeny of diatoms. It is commonly reported in coastal waters around the world, where it can form intense blooms. Its life cycle is unique among diatoms, as this is the only species in the group that forms resting stages following sexual reproduction. The transcriptome can shed light on the molecular basis of sexual reproduction and auxospore formation in diatoms, and be used as background information in metatranscriptomic investigations during blooms of the species.
