Liquid ordered domains of tobacco cell plasma membrane : in vivo visualization, spatial distribution and modulation upon elicitation
SPE IPM; International audience; The ability of lipids in complex mixtures to form liquid-ordered, sterol-rich phases, together with the association of specific proteins with sterol-enriched biochemical fractions extracted from biological membranes, gave raise to the "lipid rafts" hypothesis. This suggests the presence within biological membranes of small-sized, ordered domains, of particular lipid and protein composition, which could serve as signal transduction platforms, particularly during plant-microorganisms interactions. However, the precise organization of living cell plasma membrane is still poorly described and the spatial distribution of segregating liquid-disordered and liquid-o…
Dynamic changes in the subcellular distribution of the tobacco ROS-producing enzyme RBOHD in response to the oomycete elicitor cryptogein.
Highlight text The oomycete elicitor cryptogein triggers the relocation of RBOHD from intracellular compartments to the plasma membrane in tobacco cells. This suggests that intracellular trafficking is a potential determinant of RBOHD activity.
