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
Are elicitins cryptograms in plant-Oomycete communications?
TLDR
It is proposed that elicitins could interact with regulating cell wall proteins before they reach the plasma membrane, and the plant reactivity or nonreactivity status could result from the equilibrium reached during this interaction. Expand
Involvement of Lipoxygenase-dependent Production of Fatty Acid Hydroperoxides in the Development of the Hypersensitive Cell Death induced by Cryptogein on Tobacco Leaves*
TLDR
The results minimize the direct participation of active oxygen species from the oxidative burst in membrane lipid peroxidation and suggest the involvement of lipase activity to provide the free PUFA substrates for LOX. Expand
The structure of “defective in induced resistance” protein of Arabidopsis thaliana, DIR1, reveals a new type of lipid transfer protein
TLDR
The signaling function associated with DIR1 may be related to a specific lipid transport that needs to be characterized and to an additional mechanism of recognition by a putative receptor, as the structure displays on the surface the characteristic PxxP structural motif reminiscent of SH3 domain signaling pathways. Expand
Oligandrin. A proteinaceous molecule produced by the mycoparasite Pythium oligandrum induces resistance to Phytophthora parasitica infection in tomato plants.
TLDR
A low-molecular weight protein, termed oligandrin, was purified to homogeneity from the culture filtrate of the mycoparasitic fungus Pythium oligandrum and displayed the ability to induce plant defense reactions that contributed to restrict stem cell invasion by the pathogenic fungus Phytophthora parasitica. 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
Hydrogen peroxide induces programmed cell death features in cultured tobacco BY-2 cells, in a dose-dependent manner.
TLDR
Data suggest that H(2)O(2)-induced cell damage is associated with the induction of various cell death processes that could be involved differently in plant defence reactions. Expand
Mediation of elicitin activity on tobacco is assumed by elicitin-sterol complexes.
TLDR
The binding kinetics of elicitins are related to their biological effects, which constitutes the first evidence that binding sites could be the biological receptors. Expand
From elicitins to lipid-transfer proteins: a new insight in cell signalling involved in plant defence mechanisms.
TLDR
Recent work demonstrating that elicitins and lipid-transfer proteins share the same biological receptors gives a new perspective to understand the role played by lipid binding proteins, mainly the early recognition of intruders in plants. Expand
