| Abstract: | Chlorarachniophytes are amoeboid/flagellate eukaryotes that harbor reduced green algal endosymbionts. The carbohydrate stores of chlorarachniophyte algae have been investigated using methylation analysis to determine monosaccharide composition. An appreciable quantity of long chain β-1,3 glucan occurs in these algae. Immunogold electron microscopy using an antibody specific for (β-1,3 glucans localized (β-1,3 glucans within a vacuole in the host cell cytoplasm. The results suggest that photosynthate produced by the endosymbiont is stored by the host. Implications of the data for endosymbiosis are discussed. |
