An important step in Listeria lipoprotein research Inra
Garcia-del Portillo, F.; Cossart, P..
Over the last 10 years, DNA sequences of more than 600 bacterial species have been deposited in databases and are now available to search any gene, motif, or regulatory sequence of interest. Although genome data are instrumental in phylogenetic analysis and in silico design of metabolic and regulatory networks, only a very small fraction of the information has been experimentally validated. A striking example is lipoproteins predicted from genome sequences. Despite the predominance of this class of surface proteins in bacteria (up to 0.5 to 8% of the proteome), very few of these proteins have been identified as lipoproteins by biochemical methods (19). In this issue of the Journal of Bacteriology, Baumgärtner et al. (2) report a systematic...

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,...

Evidence for two distinct subgroups of Alfalfa mosaic virus (AMV) from France and Italy and their relationships with other AMV strains Inra
Parrella, G.; Lanave, C.; Marchoux, G.; Finetti Sialer, M.M.; di Franco, A.; Gallitelli, D..
 The nucleotide sequence of the putative coat protein open reading frame of seven previously uncharacterized AMV strains from Italy and France was determined and aligned with comparable sequences of other AMV strains (425 L, 425 M, YSMV, S, VRU, 15/64 and Da). The data set of AMV sequences was used to determine phylogenetic relationships by both a stochastic (stationary Markov model) and a deterministic method (maximum-parsimony) of analysis.The topology of the trees obtained with the two methods was essentially the same showing that all AMV strains clustered in two monophyletic groups. Close clustering of Italian strains in subgroup I and of French strains in subgroup II seems to suggests the effect of geographic distinctiveness of evolutionary dynamics...

Molecular characterization of a phospholipase C β potentially involved in moth olfactory transduction Inra
Chouquet, B.; Lucas, P.; Bozzolan, F.; Solvar, M.; Maïbèche-Coisné, M.; Durand, N.; Debernard, S..
To clarify the role of phospholipase C (PLC) in insect olfactory transduction, we have undertaken its molecular identification in the moth Spodoptera littoralis. From the analysis of a male antennal expressed sequence tag library, we succeeded in cloning a full-length cDNA encoding a PLC that belongs to the cluster of PLC-b subtypes. In adult males, the PLC-b transcript was located predominantly in brain and antennae where its presence was detected in the olfactory sensilla trichodea. Moreover, PLC-b was expressed in antennae at the beginning of the pupal stage, then reached a maximum at the end of this stage and was maintained at this level during the adult period. Taken together, these results provided molecular evidence for the putative participation of...

Molecular evolution of the crustacean hyperglycemic hormone family in ecdysozoans Inra
Montagné, N.; Desdevises, Y.; Soyez, D.; Toullec, J.-Y..
Background: Crustacean Hyperglycemic Hormone (CHH) family peptides are neurohormones known to regulate several important functions in decapod crustaceans such as ionic and energetic metabolism, molting and reproduction. The structural conservation of these peptides, together with the variety of functions they display, led us to investigate their evolutionary history. CHH family peptides exist in insects (Ion Transport Peptides) and may be present in all ecdysozoans as well. In order to extend the evolutionary study to the entire family, CHH family peptides were thus searched in taxa outside decapods, where they have been, to date, poorly investigated. Results: CHH family peptides were characterized by molecular cloning in a branchiopod crustacean, Daphnia...

Pepper mild mottle virus, a plant virus associated with specific immune responses, fever, abdominal pains, and pruritus in humans Inra
Colson, P.; Richet, H.; Desnues, C.; Balique, F.; Moal, V.; Grob, J.J.; Berbis, P.; Lecoq, H.; Harlé, J.R.; Berland, Y.; Raoult, D..
Background: Recently, metagenomic studies have identified viable Pepper mild mottle virus (PMMoV), a plant virus, in the stool of healthy subjects. However, its source and role as pathogen have not been determined. Methods and Findings: 21 commercialized food products containing peppers, 357 stool samples from 304 adults and 208 stool samples from 137 children were tested for PMMoV using real-time PCR, sequencing, and electron microscopy. Anti-PMMoV IgM antibody testing was concurrently performed. A case-control study tested the association of biological and clinical symptoms with the presence of PMMoV in the stool. Twelve (57%) food products were positive for PMMoV RNA sequencing. Stool samples from twenty-two (7.2%) adults and one child (0.7%) were...

Phylogenetic analysis of rabbit haemorrhagic disease virus in France between 1993 and 2000, and the characterisation of RHDV antigenic variants Inra
Le Gall-Reculé, G.; Zwingelstein, F.; Laurent, S.; de Boisséson, C.; Portejoie, Y.; Rasschaert, D..
 The first molecular epidemiological study of Rabbit haemorrhagic disease virus undertaken in France between 1988 and 1995, identified three genogroups, two of which (G1, G2) disappeared quickly. We used immunocapture-RT-PCR and sequencing to analyse 104 new RHDV isolates collected between 1993 and 2000. One isolate was obtained in 2000 from a French overseas territory, the Reunion Island. The nucleotide sequences of these isolates were aligned with those of some French RHDV isolates representative of the three genogroups previously identified, of some reference strains and German and American RHDV antigenic variants. Despite the low degree of nucleotide sequence variation, three new genogroups (G4 to G6) were identified with significant bootstrap values....
