Most vascular plants contain Delta(5)-sterols as the predominant type; however, a few species such as Medicago sativa, have mainly Delta(7)-sterols. The Delta(7)-sterols of alfalfa are isomers of the common Delta(5)-sterols and are generally assumed to be their immediate precursors. Light had a
Several studies have provided new insights into the role of sphingolipid/sterol-rich domains so-called lipid rafts of the plasma membrane (PM) from mammalian cells, and more recently from leaves, cell cultures, and seedlings of higher plants. Here we show that lipid raft domains, defined as Triton
BACKGROUND
Membrane microdomains are defined as highly dynamic, sterol- and sphingolipid-enriched domains that resist to solubilization by non-ionic detergents. In plants, these so-called Detergent Insoluble Membrane (DIM) fractions have been isolated from plasma membrane by using conventional
