Abstract
In the past, most grapevine trunk diseases (GTDs) have been controlled by treatments with sodium arsenite. For obvious reasons, sodium arsenite was banned in vineyards, and consequently, the management of GTDs is difficult due to the lack of methods with similar effectiveness. Sodium arsenite is known to have a fungicide effect and to affect the leaf physiology, but its effect on the woody tissues where the GTD pathogens are present is still poorly understood. This study thus focuses on the effect of sodium arsenite in woody tissues, particularly in the interaction area between asymptomatic wood and necrotic wood resulting from the GTD pathogens' activities. Metabolomics was used to obtain a metabolite fingerprint of sodium arsenite treatment and microscopy to visualize its effects at the histo-cytological level. The main results are that sodium arsenite impacts both metabolome and structural barriers in plant wood. We reported a stimulator effect on plant secondary metabolites in the wood, which add to its fungicide effect. Moreover, the pattern of some phytotoxins is affected, suggesting the possible effect of sodium arsenite in the pathogen metabolism and/or plant detoxification process. This study brings new elements to understanding the mode of action of sodium arsenite, which is useful in developing sustainable and eco-friendly strategies to better manage GTDs.

Abstract
Using plant defense elicitors to protect crops against diseases is an attractive strategy to reduce chemical pesticide use. However, development of elicitors remains limited because of variable effectiveness in the field. In contrast to fungicides that directly target pathogens, elicitors activate plant immunity, which depends on plant physiological status. Other products, the biostimulants, can improve certain functions of plants. In this study, the objective was to determine whether a biostimulant via effects on grapevine physiology could increase effectiveness of a defense elicitor. A new methodology was developed to study biostimulant activity under controlled conditions using in vitro plantlets. Both biostimulant and defense elicitor used in the study were plant extracts. When added to the culture medium, the biostimulant accelerated the beginning of plantlet growth and affected the shoot and root development. It also modified metabolomes and phytohormone contents of leaves, stems, and roots. When applied on shoots, the defense elicitor changed metabolite and phytohormone contents, but effects were different depending on whether plantlets were biostimulated or controls. Defense responses and protection against Plasmopara viticola (downy mildew agent) were induced only for plantlets previously treated with the biostimulant, Therefore, the biostimulant may act by priming the defense elicitor action. In this study, a new method to screen biostimulants active on grapevine vegetative growth was used to demonstrate that a biostimulant can optimize the efficiency of a plant defense elicitor.

Abstract
Botryosphaeria dieback is one of the most significant grapevine trunk diseases that affects the sustainability of the vineyards and provokes economic losses. The causal agents, Botryosphaeriaceae species, live in and colonize the wood of the perennial organs causing wood necrosis. Diseased vines show foliar symptoms, chlorosis, or apoplexy, associated to a characteristic brown stripe under the bark. According to the susceptibility of the cultivars, specific proteins such as PR-proteins and other defense-related proteins are accumulated in the brown stripe compared with the healthy woody tissues. In this study, we enhanced the characterization of the brown stripe and the healthy wood by obtaining a metabolite profiling for the three cultivars Chardonnay, Gewurztraminer, and Mourvèdre to deeper understand the interaction between the Botryosphaeria dieback pathogens and grapevine. The study confirmed a specific pattern according to the cultivar and revealed significant differences between the brown stripe and the healthy wood, especially for phytochemical and lipid compounds. This is the first time that such chemical discrimination was made and that lipids were so remarkably highlighted in the interaction of Botryosphaeriaceae species and grapevine. Their role in the disease development is discussed.

Abstract
Elicitors trigger plant defense responses, including phytoalexin production and cell-wall reinforcement. Primary metabolism plays an important role in these responses as it fuels the associated energetic costs and provides precursors for the synthesis of the numerous secondary metabolites involved in defenses against pathogens. In this context, we aimed to determine whether oligosaccharidic elicitors differing in their capacity to activate defense-associated secondary metabolism in grapevine would differently impact primary metabolism. To answer this question, cell suspensions were treated with two elicitors: an oligogalacturonide, and the β-glucan laminarin. Enzymatic activity assays together with targeted (HPLC) and global (GC-MS) analyses of metabolites were next performed to compare their impact on plant primary or secondary metabolism. The results showed that the oligogalacturonide, which induced the highest level of the phytoalexin resveratrol and the highest activity of stilbene synthase, also induced the highest activity of shikimate hydroxycinnamoyltransferase, a key enzyme involved in the synthesis of lignin. The oligogalacturonide-induced defenses had a significant impact on primary metabolism 24 h following elicitor treatment, with a reduced abundance of pyruvate and 2-oxoglutarate, together with an increase of a set of metabolites including carbohydrates and amino acids. Interestingly, an accumulation of galacturonate and gentiobiose was observed in the oligogalacturonide- and laminarin-treated cells, respectively, suggesting that both elicitors are rapidly hydrolyzed in grapevine cell suspension cultures.

Abstract
Poleroviruses are phytoviruses strictly transmitted by phloem-feeding aphids in a circulative and nonpropagative mode. During ingestion, aphids sample virions in sieve tubes along with sap. Therefore, any sap protein bound to virions will be acquired by the insects and could potentially be involved in the transmission process. By developing in vitro virus-overlay assays on sap proteins collected from cucumber, we observed that approximately 20 proteins were able to bind to purified particles of Cucurbit aphid borne yellows virus (CABYV). Among them, eight proteins were identified by mass spectrometry. The role of two candidates belonging to the PP2-like family (predominant lectins found in cucurbit sap) in aphid transmission was further pursued by using purified orthologous PP2 proteins from Arabidopsis. Addition of these proteins to the virus suspension in the aphid artificial diet greatly increased virus transmission rate. This shift was correlated with an increase in the number of viral genomes in insect cells and with an increase of virion stability in vitro. Surprisingly, increase of the virus transmission rate was also monitored after addition of unrelated proteins in the aphid diet, suggesting that any soluble protein at sufficiently high concentration in the diet and acquired together with virions could stimulate virus transmission.

Abstract
Background Thiomonas strains are ubiquitous in arsenic-contaminated environments. Differences between Thiomonas strains in the way they have adapted and respond to arsenic have never been studied in detail. For this purpose, five Thiomonas strains, that are interesting in terms of arsenic metabolism were selected: T. arsenivorans, Thiomonas spp. WJ68 and 3As are able to oxidise As(III), while Thiomonas sp. Ynys1 and T. perometabolis are not. Moreover, T. arsenivorans and 3As present interesting physiological traits, in particular that these strains are able to use As(III) as an electron donor. Results The metabolism of carbon and arsenic was compared in the five Thiomonas strains belonging to two distinct phylogenetic groups. Greater physiological differences were found between these strains than might have been suggested by 16S rRNA/rpoA gene phylogeny, especially regarding arsenic metabolism. Physiologically, T. perometabolis and Ynys1 were unable to oxidise As(III) and were less arsenic-resistant than the other strains. Genetically, they appeared to lack the aox arsenic-oxidising genes and carried only a single ars arsenic resistance operon. Thiomonas arsenivorans belonged to a distinct phylogenetic group and increased its autotrophic metabolism when arsenic concentration increased. Differential proteomic analysis revealed that in T. arsenivorans, the rbc/cbb genes involved in the assimilation of inorganic carbon were induced in the presence of arsenic, whereas these genes were repressed in Thiomonas sp. 3As. Conclusion Taken together, these results show that these closely related bacteria differ substantially in their response to arsenic, amongst other factors, and suggest different relationships between carbon assimilation and arsenic metabolism.

Abstract
Proteins belonging to the family of DING proteins are ubiquitous in animals and several of them are associated with various diseases. Their presence in a few plant species has previously been reported and the St John's Wort DING protein was recently described as an inhibitor of HIV replication and transcription. However, data about DING protein occurrence in plants and their biochemical properties remain almost nonexistent. We describe methods for the purification of DING proteins from plants that may have general applicability since they are not dependent upon specific affinity ligands, contrary to previously described protocols. Cibacron Blue chromatography, sometimes preceded by an ion-exchange chromatographic step, is suitable for most plant extracts. DING proteins were purified from various species and cell types and their identity was confirmed immunologically and, in some cases, by N-terminal sequence analysis, indicating that they are ubiquitous in the plant kingdom. They are associated with the cell wall and sometimes secreted in the medium for in vitro grown cells. High-molecular-weight DING precursors were often observed. Internal peptides were also sequenced, as a prelude to gene cloning experiments.

Abstract
In eucaryotes, glycolytic enzymes are classically regarded as being localised in the cytosol. Recently, we have shown that part of the cellular pool of the glycolytic enzyme, enolase, is tightly associated with the mitochondrial surface in the yeast Saccharomyces cerevisiae (N. Entelis, I. Brandina, P. Kamenski, I.A. Krasheninnikov, R.P. Martin and I. Tarassov, A glycolytic enzyme, enolase, is recruited as a cofactor of tRNA targeting toward mitochondria in Saccharomyces cerevisiae, Genes Dev. 20 (2006) 1609-1620). Here, using enzymatic assays, we show that all glycolytic enzymes are associated with mitochondria in yeast, to extents similar to those previously reported for Arabidopsis cells. Using separation of mitochondrial complexes by blue-native/SDS-PAGE and coimmunoprecipitation of mitochondrial proteins with anti-enolase antibodies, we found that enolase takes part in a large macromolecular complex associated to mitochondria. The identified components included additional glycolytic enzymes, mitochondrial membrane carriers, and enzymes of the TCA cycle. We suggest a possible role of the enolase complex in the channeling of pyruvate, the terminal product of glycolysis, towards the TCA cycle within mitochondria. Moreover, we show that the mitochondrial enolase-containing complex also contains the cytosolic tRNA(CUU)Lys, which is mitochondrially-imported, and its presumed import carrier, the precursor of the mitochondrial lysyl-tRNA synthetase. This suggests an unsuspected novel function for this complex in tRNA mitochondrial import.

Abstract
In the present study, total proteins from a tissue of an infiltrating ductal carcinoma of the breast (IDCA) were compared by the two-dimensional electrophoresis (2D-PAGE) to proteins from an adjacent non-neoplastic breast tissue. Analysis of multiple gels for each sample identified nine proteins present in the tumor sample that were less present in the matched normal adjacent breast tissue and four proteins present at higher levels in the normal tissue. The altered proteins were identified by matrix assisted laser desorption/ionization-time of flight (MALDI-TOF) mass spectrometry and search in protein databases. Protein disulfide isomerase, BiP protein, calreticulin, cathepsin D, inorganic pyrophosphatase, vimentin, apolipoprotein A1 precursor, tropomyosin 4 and beta5-tubulin were identified as being significantly over-expressed in the IDCA with regard to the normal tissue. The expression of fibrinogen E-fragment (known as anti-angiogenic factor) as well as of fibrin E, Pro2619 and actinG1 was found to be inhibited in the tumor sample. The identified proteins might play an important role during malignant transformation, breast cancer progression, and angiogenesis as well as in cellular signaling. This study demonstrates quantitative and qualitative changes in protein abundance between IDCA and normal tissue. The identification of these differentially expressed proteins could lead to a better understanding of the molecular events linked to breast cancer progression.

Abstract
Excess manganese (Mn) supply causes formation of visible brown depositions in the cell walls of leaves of cowpea (Vigna unguiculata), which consist of oxidized Mn and oxidized phenols. Because oxidation of Mn and phenolic compounds in the leaf apoplast was proposed to be catalyzed by apoplastic peroxidases (PODs), induction of these enzymes by Mn excess was investigated. POD activity increased upon prolonged Mn treatment in the leaf tissue. Simultaneously, a significant increase in the concentration of soluble apoplastic proteins in "apoplastic washing fluid" was observed. The identity of the released proteins was systematically characterized by analysis of the apoplast proteome using two-dimensional gel electrophoresis and liquid chromatography-tandem mass spectrometry. Some of the identified proteins exhibit sequence identity to acidic PODs from other plants. Several other proteins show homologies to pathogenesis-related proteins, e.g. glucanase, chitinase, and thaumatin-like proteins. Because pathogenesis-related-like proteins are known to be induced by various other abiotic and biotic stresses, a specific physiological role of these proteins in response to excess Mn supply remains to be established. The specific role of apoplastic PODs in the response of plants to Mn stress is discussed.
