| Recently, glycosphingolipids have been attracting attention due to their role on biological systems as second messengers or modulators of signal transduction, affecting several events, which range from apoptosis to regulation of the cell cycle. In pathogenic fungi, glycolipids are expressed in two classes: neutral monohexosylceramides (glucosyl-or galactosylceramide) and acidic glycosylinositol phosphorylceramides (the latter class carries longer glycan chains). It is worth to mention that monohexosylceramides exhibit significant structural differences in their lipid moieties compared to their mammalian counterparts, whereas the glycosylinositol phosphorylceramides exhibit remarkable structural differences in their carbohydrate moieties in comparison to... |

| The objective of this study was to examine the effect of two culture systems, liquid medium associated to floating membranes and solid medium, both supplemented with different concentrations of 2,4-D, in the induction of somatic embryogenesis of cassava (Manihot esculenta Crantz). Only 28% of the young leaf lobes (with 9 µM 2,4-D) were induced to form organized embryogenic structures (OES) with membrane rafts, compared to 50% of the explants presenting this type of tissue in solid medium with 36 µM of 2,4-D. Despite the lower response observed in liquid medium with membrane, the amount of OES/explant in all 2,4-D concentrations was higher than solid medium. Based on the results and considering the high cost of the membrane rafts, this system was not... |
