Lipid Rafts in Higher Plant Cells
TLDR
The data clearly indicate that tobacco microdomains are able to recruit a specific set of the plasma membrane proteins and exclude others, and it is demonstrated the recruitment of the NADPH oxidase after elicitation by cryptogein and the presence of the small G protein NtRac5, a negative regulator of NADPH oxidation, in lipid rafts.

Proteomics of Plant Detergent-resistant Membranes * S
TLDR
Analysis of the lipidic composition of a tobacco plasma membrane fraction resistant to solubilization with Triton X-100 revealed its enrichment in sphingolipids and sterols and depletion in phospho- and glycerolipidas as previously observed for animal microdomains. Expand
Cadmium affects tobacco cells by a series of three waves of reactive oxygen species that contribute to cytotoxicity.
TLDR
It is shown that the accumulation of O(2) (-*) of mitochondrial origin and membrane peroxidation are key players in Cd(2+)-induced cell death and trigger all the cadmium-dependent deleterious effects. Expand
Remorin, a Solanaceae Protein Resident in Membrane Rafts and Plasmodesmata, Impairs Potato virus X Movement[W]
TLDR
It is shown that REM can interact physically with the movement protein TRIPLE GENE BLOCK PROTEIN1 from PVX and the potential for lipid rafts to act as functional components in plasmodesmata and the plasma membrane is discussed. Expand
Sugar transporters in plants and in their interactions with fungi.
TLDR
The essential role of sugar transporters for distribution of carbohydrates inside plant cells, as well as for plant-fungal interaction functioning is reviewed to highlight the need for a better comprehension of the mechanisms underlying sugar exchanges between fungi and their host plants. Expand
The plasma membrane oxidase NtrbohD is responsible for AOS production in elicited tobacco cells.
TLDR
This work represents the first demonstration of the function of a homologue of gp91-phox in AOS production in elicited tobacco cells. Expand
Depletion of phytosterols from the plant plasma membrane provides evidence for disruption of lipid rafts
TLDR
The results support the role of phytosterols in the lateral structuring of the PM of higher plant cells and suggest that they are key compounds for the formation of plant PM microdomains. Expand
Lipids of plant membrane rafts.
TLDR
This review focuses on the history of raft discovery in animals and plants, the main findings about structural and signalling plant lipids involved in raft segregation, imaging of plant membrane domains, and their biochemical purification through detergent-insoluble membranes, as well as the existing debate on the topic. Expand
Quantitative Proteomics Reveals a Dynamic Association of Proteins to Detergent-resistant Membranes upon Elicitor Signaling in Tobacco*
TLDR
Comparing the content of tobacco detergent-resistant membranes extracted from cells treated or not with cryptogein, an elicitor of defense reaction, indicates that plant microdomains could, like their animal counterpart, play a role in the early signaling process underlying the setup ofdefense reaction. Expand
Rac regulation of NtrbohD, the oxidase responsible for the oxidative burst in elicited tobacco cell.
TLDR
Ntrac5 could be considered as a negative regulator of NtrbohD, the oxidase involved in AOS production upon elicitation, which is affected at both transcriptional and translational levels in cells overexpressing Ntrac 5. Expand
