Differentiation of peanut clump virus serotypes by monoclonal antibodies IRD
Huguenot, C.; Givord, Louise; Sommermeyer, G.; Van Regenmortel, M.H.V..
Des anticorps monoclonaux dirigés contre le virus du "clump" de l'arachide ont permis de caractériser 5 sérotypes du virus. La comparaison de 4 types de tests immunoenzymatiques ELISA a permis de sélectionner celui qui est le mieux adapté au diagnostic de routine et à la différenciation entre sérotypes du virus. La plupart des anticorps monoclonaux conservent leur activité après adsorption sur la phase solide en ELISA, et le même anticorps peut être utilisé comme capteur et comme anticorps biotinylé. Etant donné que les anticorps obtenus sont capables de reconnaître des changements mineurs de conformation de l'antigène viral, il est important de sélectionner avec soin le format du test ELISA utilisé dans les comparaisons entre différents isolats du virus....

Pectinase-hyperproducing mutants of Aspergillus niger C28B25 for solid-state fermentation of coffee pulp IRD
Antier, Philip; Minjares, A.; Roussos, Sevastianos; Raimbault, Maurice; Viniegra-Gonzalez, G..
The aim of this study was to improve mold strains for the production of pectinases by solid-state fermentation (SSF) of coffee pulp. A screening of 248 strains, isolated in Mexico's coffee-growing areas, permitted us to select a wild strain of #Aspergillus niger$ which in 72 h attains a peak production of 27.7 U ml-1(138 U g-1 dry pulp) of pectinase measured by viscosimetry. Though the use of a selective culture medium with low water activity (aw = 0.954) with 2-deoxy-glucose (2DG) it was possible to isolate pectinase-hyperproductive mutant strains for SSF(44.5 U ml-1, 228 U g-1 dry pulp). Derepressed mutant strains that hyperproduced pectinase by submerged fermentation (SmF) were also obtained using a classic selective medium with high water activity...

Studies on by-products from the industrial extraction of alginate. 2. Chemical structure analysis of fucans from the leach-water Inra
Fleury, N.; Lahaye, M..
The chemical composition of fucans isolated from leach-water, an industrial alginate extraction by-product, was investigated. Several fractions were obtained by anion exchange and gel permeation chromatography. They all contained fucose, but differed in the uronic acid, sulfate, xylose and galactose contents. They distributed as a continuum between uronic acid rich and sulfate poor to sulfate rich and uronic acid poor molecules. Two highly sulfated fractions were studied in particularly by chemical means (methylation, carboxy reduction, desulfation, controlled acid hydrolysis) and by13C nuclear magnetic resonance spectroscopy. One fraction consisted of a highly branched fucan (43.8% fucose) composed mostly of 1,2,3,4- and 1,2,4-linked fucose with some...

Characterization of resistance breaking Meloidogyne incognita - like populations using lectins, monoclonal antibodies and spores of Pasteuria penetrans IRD
Fargette, Mireille; Davies, K.G.; Robinson, M.P.; Trudgill, D.L..
Six clones de #Meloidogyne$, provenant de populations récoltées en Côte d'Ivoire et qui possèdent un phénotype estérasique particulier (codé pVI) ainsi que la faculté de briser la résistance conférée par le gène #Mi$, ont été comparés à #M. incognita$ à l'aide de différentes sondes. Le marquage à l'aide de lectines des exsudats amphidiaux de juvéniles de second stade ne permet pas de distinguer ces lignées de #M. incognita$. Des souches de #Pasteuria penetrans$ permettent de les distinguer et mettent aussi en évidence une certaine variabilité au sein de ce groupe. Deux anticorps monoclonaux, spécifiques de #M. incognita$ indiquent que les clones de phénotype pVI partagent certains caractères avec #M. incognita$ mais aussi qu'ils s'en distinguent. (Résumé...

Shoot-root control of nitrate tolerance of N2 fixation in spontaneously tolerant soybean lines: reciprocal grafting experiments Inra
Raffin, A.; Roumet, P..
Une caractérisation de la tolérance au nitrate de la fixation de l’azote chez le soja a été réalisée dans 2 expérimentations de greffes réciproques, avec des dispositifs de types top cross et diallèle. Le contrôle de la tolérance au nitrate par les parties aériennes et racinaires de la plante a été étudié chez une lignée tolérante (Tielingbaime), un cultivar sensible (Kingsoy), et 5 lignées issues de leur croisement. Les 2 expérimentations ont démontré l’existence d’un contrôle par la partie aérienne de la tolérance au nitrate de la nodulation. Le caractère de tolérance permet le maintien de nodosités en plus grand nombre et de masse spécifique supérieure en présence de nitrate. La régulation de la fixation de l’azote en présence de nitrate serait...

Comparative analysis of sulfated galactans from red algae by reductive hydrolysis and mild methanolysis coupled to two different HPLC techniques Inra
Quemener, B.; Lahaye, M..
The sugar determination of the sulfated galactans, agars and carrageenans of various red algae was performed using two different techniques of depolymerisation with subsequent HPLC analysis: 1) reductive hydrolysis/ HPAEC-PAD; 2) mild methanolysis/ RPLC-DR. Both techniques were optimized to release quantitatively the composite sugars (galactose, 6-O-methyl-galactose, the labile 3,6-anhydrogalactose and 2-O-methyl-3,6-anhydrogalactose residues) and precise relative response factors of authentic 3,6-anhydrogalactose were determined. The methanolysate neutralisation step, performed subsequently to methanolysis depolymerisation, was demonstrated as a key step for the quantitative recovery of the anhydrogalactose residues. The yield of the main sugars released...

Characterisation of the microbial 16S rDNA diversity of an aerobic phosphorus-removal ecosystem and monitoring of its transition to nitrate respiration Inra
Dabert, P.; Sialve, B.; Delgenès, J.P.; Moletta, R.; Godon, J.J..
The microbial community of a conventionalanaerobic–aerobic sequencing batch reactor was investigated by cloning and sequencing bacterial 16S rDNA. The 92 16S rDNA sequences analysed ranged across 50 different operational taxonomic units (OTU). The majority of these sequences were not closely related to known species. They belonged to 12 different groups, but essentially to the Cytophagales and the Proteobacteria beta, which represented 38% and 17% of the retrieved sequences respectively. No OTU numerically outnumbered the others. However, similarities were observed with previous reports on molecular characterisation of phosphorus-accumulating ecosystems, suggesting an enrichment in microorganisms belonging to the Rhodocyclus group. Thereafter,...

Mapping the paratope of anti-CD4 recombinant fab 13B8.2 by combining parallel peptide synthesis and site-directed mutagenesis Inra
Bès, C.; Briand-Longuet, L.; Cerutti, M.; Heitz, F.; Troadec, S.; Pugnière, M.; Roquet, F.; Molina, F.; Casset, F.; Bresson, D.; Péraldi-Roux, S.; Devauchelle, G.; Devaux, C.; Granier, C.; Chardès, T..
We analyzed antigen-binding residues from the variable domains of anti-CD4 antibody 13B8.2 using the Spot method of parallel peptide synthesis. Sixteen amino acids, defined as Spot critical residues (SCR), were identified on the basis of a 50% decrease in CD4 binding to alanine analogs of reactive peptides. Recombinant Fab 13B8.2 mutants were constructed with alanine residues in place of each of the 16 SCR, expressed in the baculovirus cell system, and purified. CD measurements indicated that the mutated proteins were conformationally intact, with a β-sheet secondary structure similar to that of wild-type Fab. Compared with the CD4-binding capacity of wild-type Fab 13B8.2, 11 light (Y32-L, W35-L, Y36-L, H91-L, and Y92-L) and heavy chain (H35-H, R38-H,...

Molecular characterization of banana virus X (BVX), a novel member of the Flexiviridae family Inra
Teycheney, P.Y.; Marais, A.; Svanella-Dumas, L.; Dulucq, M.J.; Candresse, T..
A novel virus was identified in banana (Musa spp). Analysis of the last 2917 nucleotides of its positive strand genomic RNA showed five open reading frames corresponding, from 5′ to 3′, to a truncated ORF coding for a replication-associated protein, three ORFs coding for a movement-associated triple gene block (TGB) and a capsid protein (CP) gene. This genome organization is similar to that of some members of the Flexiviridae family such as potexviruses and foveaviruses. This virus was named Banana virus X (BVX). Comparative sequence analysis showed that BVX is only distantly related to other members of the Flexiviridae family, in which it appears to define a new genus. BVX produces defective RNAs derived from its genomic RNA by non-homologous...

Characterization and partial genome sequence of stocky prune virus, a new member of the genus Cheravirus Inra
Candresse, T.; Svanella-Dumas, L.; Le Gall, O..
Characterization of a seemingly new spherical virus isolated from severely affected plum trees in south-western France indicated that its divided genome is composed of two single-stranded, polyadenylated RNAs of approximately 7.4 and 3.7 kb. Its particles are composed of three coat protein subunits of approximately 23, 23.5, and 24.5 kDa. Partial sequencing of the genomic RNAs indicated that this new virus, tentatively named stocky prune virus (StPV), is distantly related to the two sequenced cheraviruses, cherry rasp leaf virus (CRLV) and apple latent spherical virus (ALSV). StPV should be regarded as a new member in the unassigned genus Cheravirus.

Characterization of viticultural terroirs using a simple field model based on soil depth I. Validation of the water supply regime, phenology and vine vigour, in the Anjou vineyard (France) Inra
Bodin, F.; Morlat, R..
The soil and climate in which grapes are grown play a major role in the vine behaviour, grape quality and wine sensory characteristics. In France, these factors are often integrated in the concept of "Terroir", which is a topic of growing interest in wine producing countries. The application of this concept requires a scientific approach of the "Terroir climatic and pedoclimatic components" to achieve a rigorous zoning of vineyards. In this paper, results concerning the testing of a method developed in the Anjou vineyard (France) to characterize viticultural terroirs, are presented and discussed. This method uses a field soil model based on the type of parent rock, the depth and the clay richness of soil, mainly in connection with the weathering level of...
