Guillardia is a genus of flagellate cryptomonad algae belonging to the family Geminigeraceae, containing a secondary plastid within a reduced cytoplasmic compartment that contains a vestigial nucleomorph. There is only one characterised member of this genus, Guillardia theta.

Genomes[edit]

Guillardia theta was the first cryptophyte to have its nuclear genome sequenced. The genome contains 87 Mbp, encoding around 24,840 genes.[1] The complete nucleomorph[2] and plastid [3] genomes have been sequenced, containing 551 kbp and 121 kbp respectively.
