Importance of organism and transcriptomes	T. antarctica is endemic to the Southern Ocean and is among the dominant diatom species of the land-remote Antarctic Circumpolar Current (ACC). It constitutes a major component of the siliceous opal belt surrounding Antarctica due to its heavily silicified cell walls. This transcriptome is part of a comparative study of the transcriptomic responses of Southern Ocean diatoms to iron limitation.
