Some varieties of wheat are resistant to some aphid clones of the English Grain Aphid (Sitobion avenae). This study used 2D-DIGE coupled with protein identification by Maldi-Tof-MS to compare the proteome patterns of English Grain Aphids on resistant (Llareta) and susceptible (Huayún) wheat lines. Aphids were exposed to wheat during 2 weeks (short term: ST) and 4 weeks (long term: LT). Four treatments were compared: Llareta-ST, Llareta-LT, Huayún-ST, Huayún-LT. Experiment was conducted using different Sitobion avenae clones whose symbionts were previously characterized. Results showed that aphids had low performance on resistant plants. Seventy-two protein spots showed significant quantitative differences among the four treatment groups. Proteomic approach will allow a better understanding of interaction mechanisms between aphids and wheat. [less ▲]

Four Fumaria species (F. vaillantii Loisel, F. parviflora Lam., F. rostellata Knaf and F. jankae Hausskn.) were analysed in order to determine the presence of the isoquinoline alkaloids allocryptopine, chelidonine, protopine, bicuculline, sanguinarine, cheleritrine, stylopine, and hydrastine through an HPLC-DAD method. Protopine and sanguinarine were present in all extracts. Bicuculline and stylopine were found in F. vaillantii and F. parviflora, whilst chelidonine was identified only in F. vaillantii and hydrastine in F. jankae, so they represent potential taxonomic markers that differentiate the four plants. The richest species in isoquinoline alkaloids was F. parviflora. Our study showed significant differences between the four Fumaria species, both qualitative and quantitative. [less ▲]

Nicotinic acetylcholine receptors (nAChRs) are one of the most important families in the ligand-gated ion channel superfamily due to their involvement in primordial brain functions and in several neurodegenerative pathologies. The discovery of new ligands which can bind with high affinity and selectivity to nAChR subtypes is of prime interest in order to study these receptors and to potentially discover new drugs for treating various pathologies. Predatory cone snails of the genus Conus hunt their prey using venoms containing a large number of small, highly structured peptides called conotoxins. Conotoxins are classified in different structural families and target a large panel of receptors and ion channels. Interestingly, nAChRs represent the only subgroup for which Conus has developed seven distinct families of conotoxins. Conus venoms have thus received much attention as they could represent a potential source of selective ligands of nAChR subtypes. We describe the mass spectrometric based approaches which led to the discovery of a novel α-conotoxin targeting muscular nAChR from the venom of Conus ermineus. The presence of several posttranslational modifications complicated the N-terminal sequencing. To discriminate between the different possible sequences, analogs with variable N-terminus were synthesized and fragmented by MS/MS. Understanding the fragmentation pathways in the low m/z range appeared crucial to determine the right sequence. The biological activity of this novel α-conotoxin (α-EIIA) that belongs to the unusual α4/4 subfamily was determined by binding experiments. The results revealed not only its selectivity for the muscular nAChR, but also a clear discrimination between the two binding sites described for this receptor. [less ▲]

As a consequence of anthropogenic pressure, landscapes change; deforestation is a well-known example of this type of human-driven landscape change. Landscapes change 42 from entirely natural to anthropogenic or cultural, in which landscape composition is marked by land covers and uses directly related to the civil society, such as degraded vegetations, agriculture, urban zones, or road networks. Landscape dynamics can be quantified by landscape pattern analysis. Many landscape metrics are available to capture the different features of pattern change. As a consequence of the pattern/process paradigm, the ecological consequences of the observed dynamics can be linked to ecosystem processes and characteristics, such as biodiversity. By means of a series of case studies linking field observations of fauna and flora with cartographic and demographic data, the importance of pattern analysis and landscape management is underlined, as well as the diversity in types of anthropogenic landscape change. Conclusions are drawn with regard to the ecological impact of landscape change. Guidelines are formulated for the characterization and analysis of anthropogenic effects in landscapes by means of pattern analysis. [less ▲]

Non-stationary systems, which are commonly encountered in many fields of science, are characterized by time-varying features and require time-frequency methods for their analysis. This study considers the problem of identification and model updating of a non-stationary vibrating system. In particular, a number of identification methods and a model updating procedure are evaluated and compared through application to a time-varying “bridge-like” laboratory structure. The identification approaches include Frequency Response Function based parameter estimation techniques, Subspace Identification and Functional Series modelling. All methods are applied to both output-only and input-out-put data. Model updating is based upon a theoretical model of the structure obtained using a Rayleigh-Ritz methodology, which is updated to account for time-dependence and nonlinearity via the identification results. Interesting comparisons, among both identification and model updating results, are performed. The results of the study demonstrate high modelling accuracy, illustrating the effectiveness of model updating techniques in non-stationary vibration modelling. [less ▲]

A soluble protein that specifically bound 125I-human growth hormone (hGH) was identified in rainbow trout plasma, using HPLC-gel filtration. The binding affinity of the protein for hGH was 1.2 x 10(9)M-1. 125I-rainbow trout GH (tGH) was also able to bind to the protein albeit with a lower affinity (6.6 x 10(7)M-1) than hGH. Crosslinking experiments using 125I-hGH revealed two specific bands of 150 and 130 kDa. The complex 125I-hGH-BP could be precipitated by a monoclonal anti-GH receptor antibody, suggesting a close relationship between the plasma GH-BP and the GH receptor. A fourfold increase in the hGH binding to the GH-BP was shown 48 h after transfer of the fishes from freshwater to seawater. The increase in binding was related to a high binding capacity without significant changes in binding affinity. These results suggest a potential role of this related GH-BP as an index of GH effects during seawater adaptation in salmonids. [less ▲]

Cosmid B577, a member of the collection of ordered clones corresponding to the genome of Mycobacterium leprae, contains a gene, provisionally called pon1, that encodes an 821-amino-acid-residue high-molecular-mass class A penicillin-binding protein, provisionally called PBP1. With similar amino acid sequences and modular designs, M. leprae PBP1 is related to Escherichia coli PBP1a and PBP1b, bienzymatic proteins with transglycosylase and transpeptidase activities. When produced in E. coli, His tag-labelled derivatives of M. leprae PBP1 adopt the correct membrane topology, with the bulk of the polypeptide chain on the surface of the plasma membrane. They defy attempts at solubilization with all the detergents tested except cetyltrimethylammonium bromide. The solubilized PBP1 derivatives can be purified by affinity chromatography on Ni2+-nitrilotriacetic acid agarose. They have low affinities for the usual penicillins and cephalosporins. [less ▲]

This paper reports the identification of biomarkers resulting from the exposure of MCF-7/BOS cells to 17β-estradiol (E2). The biomarkers were identified using 2 independent and complementary techniques, 2-D DIGE / MALDI-TOF peptide mass fingerprint, and 2-D UPLC-ESI MS/MS. These markers form a preliminary molecular signature that can be used when testing the estrogenic activity of xenobiotics, either pure or in mixtures. [less ▲]
