Transcriptome analysis reveals nuclear-encoded proteins for the maintenance of temporary plastids in the dinoflagellate Dinophysis acuminata.

ABSTRACT:

Background

Dinophysis is exceptional among dinoflagellates, possessing plastids derived from cryptophyte algae. Although Dinophysis can be maintained in pure culture for several months, the genus is mixotrophic and needs to feed either to acquire plastids (a process known as kleptoplastidy) or obtain growth factors necessary for plastid maintenance. Dinophysis does not feed directly on cryptophyte algae, but rather on a ciliate (Myrionecta rubra) that has consumed the cryptophytes and retained their plastids. Despite the apparent absence of cryptophyte nuclear genes required for plastid function, Dinophysis can retain cryptophyte plastids for months without feeding.

Results

To determine if this dinoflagellate has nuclear-encoded genes for plastid function, we sequenced cDNA
