“…arborescens coming from collection sites nearby the sea showed similar β ‐thujone and chamazulene contents. The environmental conditions, especially drought, can strongly influence the composition of plant lipophilic fraction due to their influence on the physiological mechanisms linked to the secondary metabolism . In the present study, we found that sesquiterpenes were lower and monoterpenes higher in the EO coming from the relatively arid (Algeria) than the relatively humid (Italy) environments.…”

Aerial parts of Artemisia arborescens were collected from different sites of the Mediterranean area (southwestern Algeria and southern Italy) and the chemical composition of their essential oil (EO) extracted by hydrodistillation was studied by both gas chromatography (GC) equipped with an enantioselective capillary column and GC/mass spectrometry (GC/MS). The EOs obtained were tested against several Listeria monocytogenes strains. Using GC and GC/MS, 41 compounds were identified, accounting for 96.0 -98.8% of the total EO. All EOs showed a similar terpene profile, which was rich in chamazulene, b-thujone, and camphor. However, the concentration of such compounds varied among the EOs. A. arborescens EO inhibited up to 83.3% of the L. monocytogenes strains, but the inhibitory spectrum varied among the EOs, with those from Algeria showing a higher inhibition degree than the Italian EOs. Such effect likely depended on the ketone (b-thujone + camphor) content of the EO. The differences in the EO composition support the hypothesis that A. arborescens has at least two different chemotypes: a b-thujone and a chamazulene type. The EO inhibitory spectrum indicates the A. arborescens EO as a valuable option in the control of the food-borne pathogens.

“…The first version of MBROLE contained functional (biological) data on compounds from several public databases, including the Kyoto Encyclopedia of Genes and Genomes (KEGG) ( 9 ), the Human Metabolome Database (HMDB) ( 10 ), the Chemical Entities of Biological Interest (ChEBI) database ( 11 ) and the PubChem database (pubchem.ncbi.nlm.nih.gov). MBROLE has been used to analyse metabolomics experiments carried out in organisms such as human ( 12 ), rat ( 13 ), Escherichia coli ( 14 ), Thermobifida fusca ( 15 ), Synechococcus elongates ( 16 ), Phoenix canariensis ( 17 ) or Cordyceps bassiana ( 18 ).…”

MBROLE 2.0—functional enrichment of chemical compounds

Metabolites Biological Role (MBROLE) is a server that performs functional enrichment analysis of a list of chemical compounds derived from a metabolomics experiment, which allows this list to be interpreted in biological terms. Since its release in 2011, MBROLE has been used by different groups worldwide to analyse metabolomics experiments from a variety of organisms. Here we present the latest version of the system, MBROLE2, accessible at http://csbg.cnb.csic.es/mbrole2. MBROLE2 has been supplemented with 10 databases not available in the previous version, which allow analysis over a larger, richer set of vocabularies including metabolite–protein and drug–protein interactions. This new version performs automatic conversion of compound identifiers from different databases, thus simplifying usage. In addition, the user interface has been redesigned to generate an interactive, more intuitive representation of the results.

“…An important goal for the RPW management will be the identification of RPW-regulated genes associated with the symptomatology in order to analyse them with both lab or infield instruments. Previous transcriptomic and metabolomic analysis highlighted the upregulation of pathways linked with biotic stress response as well as the early induction of some members of WRKY transcription factors (Giovino et al 2015(Giovino et al , 2016.…”

The Red Palm Weevil (RPW), Rhynchophorus ferrugineus, is one of the major pests affecting several palm species all around the world. The aim of this work was to identify palm genes that are responsive to RPW infestations as a valuable diagnostic tool to detect the insect attack. We have analysed a total of 15 genes that were divided in two subsets: (1) 7 genes previously linked with RPW attacks, but not involved in biotic stress responses, and (2) 8 genes encoding members of the WRKY family, a class of transcription factors well-known to be linked with both abiotic and biotic stress responses. The analysis was conducted on 4-year-old Canary palms comparing uninfested plants and infested plants at 30 and 45 days after RPW oviposition. Principal component analysis of gene expression data showed that the overall analysis of WRKYs partially distinguished the three groups of plants. No separation of the three groups was observed when PCA was conducted using genes that were not linked with biotic stress responses. Among the 8 analysed WRKYs, 4 genes (WRKY2, WRKY28, WRKY14, WRKY51) were significantly induced by RPW attacks at 45 days after the beginning of the infestation. These four WRKYs could be further investigated to confirm if they may be used to help diagnosis of RPW infestations in palm.
