| Abstract: | Greening and shoot-differentiation related changes in lipid composition were studied in callus cultures of Datura innoxia. Both processes were associated with an increase in the content of the total lipids and the galactolipid fraction. There was also an increase in the relative level of chloroplast specific monogalactosyl diglyceride. The membrane lipid composition of tissues at different degrees of differentiation revealed an apparently inverse relationship between the degree of differentiation and the absolute as well as the relative level of phosphatidylinositol. The results are discussed with respect to the relevance of changes in membrane lipid composition during differentiation. |
