Project description:The aim of this study was to elucidate which changes in gene expression are related to the induced anti-herbivory response in the brown seaweed Fucus vesiculosus. Microarray hybridizations were used to identify genes differentially expressed in response to grazing by the isopod Idotea baltica. This study shows that modifications in gene expression occur simultaneously to a reduced palatability and that defence induction entails reallocation of resources from primary to secondary metabolism with down-regulation of photosynthesis and degradation of storage compounds.

Comparative TMT-based quantitative proteomic analysis of the Tachaea chinensis isopod during parasitism

Project description:Parasitic isopods perforate and attach to the host integument via the mandibles, then feed on hemolymph and exudate from the wounds. Such isopods attack a variety of commercially important fish and crustacean hosts. Like other hematophagous parasites, isopods employ biomolecules that inhibit host blood conglutination and defense. In the present study, a tandem mass tag-based quantitative proteomic approach was used to identify differentially expressed proteins in Tachaea chinensis parasites of shrimp, by comparing parasitic (fed) and pre-parasitic (unfed) individuals. We identified 888 proteins from 1510 total peptides, with a significant difference in 129 between the fed and unfed groups. Among these, 37 were upregulated and 92 were downregulated in unfed T. chinensis. This indicates that T. chinensis may require more energy before parasitism during its search for a host. In addition, as is the case for other blood-sucking parasites, it might secrete antihemostatic, anti-inflammatory and immunomodulatory molecules to facilitate blood meal acquisition. Our study is the first to use a TMT-based proteomic approach to analyze the proteome of isopod parasites, and our results will facilitate our understanding of the molecular mechanisms of isopod parasitism on crustaceans.
