Abstract
Cryptomonads are unicellular algae with plastids surrounded by four me mbranes. Between the two pairs of membranes lies a periplastidal compa rtment that harbours a DNA-containing organelle, termed the nucleomorp h. The nucleomorph is the vestigial nucleus of a phototrophic, eukaryo tic endosymbiont. Subcloning of parts of one nucleomorph chromosome re vealed a gene coding for an Hsp70 protein. We demonstrate the expressi on of this nucleomorph protein-coding gene and present a model for pro tein transport from the host to the endosymbiont compartment.
