Lipids of Acetabularia Mediterranea. Composition, Cellular Localization and Biosynthesis
Many questions arise about the biosynthesis, the cellular localization and the function of the betaine lipid diacylglyceryltrimethylhomoserine (DGTS) which is widely distributed among cryptogamic green plants1, 2. In Chlamydomonas, we previously found 15% of the toal DGTS to be localized in the thylakoid membranes3, while other authors found this proportion to be 40% in the same organism4 and even 90% in Dunaliella 5. In the present experiments, we used Acetabularia because cell fractionation is easier with this alga, compared to other organisms.
