Diversity of transcripts and transcript processing forms in plastids of the dinoflagellate alga Karenia mikimotoi.

ABSTRACT: Plastids produce a vast diversity of transcripts. These include mature transcripts containing coding sequences, and their processing precursors, as well as transcripts that lack direct coding functions, such as antisense transcripts. Although plastid transcriptomes have been characterised for many plant species, less is known about the transcripts produced in other plastid lineages. We characterised the transcripts produced in the fucoxanthin-containing plastids of the dinoflagellate alga Karenia mikimotoi. This plastid lineage, acquired through tertiary endosymbiosis, utilises transcript processing pathways that are very different from those found in plants and green algae, including 3' poly(U) tail addition, and extensive substitutional editing of transcript sequences. We have sequenced
