Protein trafficking pathways to plastids are directed by N-terminal
targeting peptides. In plants this consists of a relatively simple transit
peptide, while in organisms with secondary plastids (which reside within
the endomembrane system) a signal peptide is appended to the transit
peptide. Despite amino acid compositional differences between organisms,
often due to nucleotide biases, the features of plastid targeting sequences
are generally consistent within species. Dinoflagellate algae deviate from
this trend. We have conducted an expressed sequence tag (EST) survey of
the peridinin-plastid containing dinoflagellate Heterocapsa triquetra to
