Descripción: The chemical composition of cell walls (thecae) of three taxa of scaly flagellates (Prasinophyceae) was investigated. The theca of Tetraselmis striata, Tetraselmis tetrathele , and Scherffelia dubia consists mainly of carbohydrate, with proteins calcium, and sulfate as minor components. The principal sugars are 2-keto-sugar acids. Arabinose, gulose, galactose, galacturonic acid, and in S. dubia , xylose and rhamnose were also found. Examination of scale preparations from Mantoniella squamata, Mesostigma viride, Pyramimonas amylifera , and Nephroselmis olivacea revealed that the 2-keto-sugar acids were always associated with the presence of typical prasinophycean scales on the cell surface. In contrast, 2-keto-sugar acids were not detected in Chlamydomonas reinhardtii, Dunaliella bioculata, Dunaliella primolecta, Asteromonas gracilis, Hafniomonas reticulata, Pedinomonas tuberculata, Monomastix sp., and Micromonas pusilla . The authors conclude that 2-keto-sugar acids are chemical markers for prasinophycean scales.
