First identification of polymorphic microsatellite markers in the Burgundy truffle, Tuber aestivum (Tuberaceae)

2014

SPEIPMCT2Pour cette revue, la version de l'éditeur est autorisée mais il y a un embargo d'un an (mentionné dans les Conditions générales : "On Institutional Repositories after 12 months").On peut donc mettre la PJ en "publique" mais il faut indiquer une date d'embargo (un an à partir de la date de publication).

Laissée lors du dépôt en workflow par prudence.; Premise of the study: Tuber aestivum, the most common truffle in Europe, plays an important role in the commercial truffle market. For the first time, microsatellite primers were developed to investigate polymorphism within this species. • Methods and Results: Using direct shotgun pyrosequencing, 15…

Infection by Endosymbiotic “Male-Killing” Bacteria in Coleoptera

2018

Wolbachia, Rickettsia, Spiroplasma and Cardinium are endosymbiotic and intracellular bacteria known to cause numerous disorders in host reproduction, reflected in their common name “male-killers”. In this study, 297 beetle species from various taxonomic groups were screened with the use of molecular markers for the presence of infection by any of these endosymbionts. Wolbachia was found to be the most common “male-killer” among beetle hosts as it infected approx. 27% of species. Rickettsia, Spiroplasma and Cardinium were much less prevalent as they infected: 8%, 3% and 2%, respectively, of the studied beetle species. This is the first report of Cardinium presence in beetle hosts. Incidences…

Consumer preferences for fig fruit (Ficus carica L.) quality attributes and postharvest storage at low temperature by in-store survey and focus group

2017

Fig (Ficus carica L.) is cultivated mainly in southern Italy and in several countries of the Mediterranean area. According to official statistics the quantities of fresh fig placed on domestic market are low, though the home consumption is known to be relatively high in summer. The objective of this study was to discover consumers’ preferences for sensory, quality attributes of fresh fig and primary drivers of liking, in order to enhance fruit marketing value. An in-store consumer test and two focus groups were carried out to assess preferences in regards to fresh figs after 3 and 7 days of storage at low temperature: the selected sensory, intrinsic and extrinsic attributes were ranked by c…

Genetic Structure of the Limecola Balthica Population in the Gulf of Riga, Baltic Sea

2020

Abstract Samples of Limecola balthica with normal and deformed shells were collected from ten sites throughout the Gulf of Riga. Genetic diversity was evaluated by the retrotransposon-based iPBS method. Samples had close mutual genetic distances, which showed that all of them belong to one wider population of the Gulf of Rīga. No direct relationship between the activity of retrotransposons and deformation of shells was found.

Restricted geographic distribution and low genetic distinctiveness of steppic Crioceris quinquepunctata (Coleoptera: Chrysomelidae) populations in Ce…

2019

Crioceris quinquepunctata is a European leafbeetle, rare and strictly associated with steppe-like habitats in Central and Eastern Europe. We sampled suitable localities in Central East Europe to determine the current distribution and to verify whether populations isolated by the Carpathian Mountains (within Pannonian and Pontic area) show genetic differentiation. Sequences from the beetle COI and ITSl were amplified and compared. Furthermore, ftsZ and hcpA genes of the endosymbiont Wolbachia were analysed as additional genetic markers. We found only two populations of C. quinquepunctata (in Moravia and Podolian Upland). Unusually low genetic differences between these populations were reveal…

Effect of Multiple Parasitic Infections on the Tolerance to Pollutant Contamination

2012

8 pages; International audience; The horizontally-transmitted acanthocephalan parasite Polymorphus minutus and the vertically-transmitted microsporidian parasite Dictyocoela roeselum have both been shown to influence on the antitoxic responses of mono-infected Gammarus roeseli exposed to cadmium. The present study investigates the effect of this co-infection on the antitoxic defence responses of naturally infected females exposed to cadmium stress. Our results revealed that, depending on the cadmium dose, bi-infection induced only slight, significant increased cell damage in G. roeseli as compared to non-infection. In addition, the antitoxic defence pattern of cadmium-exposed bi-infected ho…

2010

4 pages; International audience; This article documents the addition of 220 microsatellite marker loci to the Molecular Ecology Resources Database. Loci were developed for the following species: Allanblackia floribunda, Amblyraja radiata, Bactrocera cucurbitae, Brachycaudus helichrysi, Calopogonium mucunoides, Dissodactylus primitivus, Elodea canadensis, Ephydatia fluviatilis, Galapaganus howdenae howdenae, Hoplostethus atlanticus, Ischnura elegans, Larimichthys polyactis, Opheodrys vernalis, Pelteobagrus fulvidraco, Phragmidium violaceum, Pistacia vera, and Thunnus thynnus. These loci were cross-tested on the following species: Allanblackia gabonensis, Allanblackia stanerana, Neoceratitis …

Crocus sativus L. Ecotypes from Mediterranean Countries: Phenological, Morpho-Productive, Qualitative and Genetic Traits

2021

The characterization of C. sativus ecotypes is of great interest for preserving them from a possible genetic erosion due to the decrease of European cultivation surface. In this study, we evaluated four ecotypes from Italy (Sardinia and Abruzzo), Spain (Castilla-La Mancha), and Greece (Kozani) in order to detect the existence of variability and promote the biodiversity of this crop. Thirty-one traits related to saffron flowering, flower morphology, production of spice and daughter corms, vegetative development (leaf and corm traits), and spice quality, were evaluated. In addition, a genetic analysis through three PCR-based approaches, SSRs, RAPD, and SRAP was assessed. Results highlighted a…

Chemical–Physical, sensory analyses and consumers’ quality perception of local vs. imported loquat fruits: a sustainable development perspective

2020

Local products and their distribution through short supply chains play a key role in the sustainable development of many rural areas, as affirmed by the 2030 Food and Agriculture Organization of the United Nations (FAO) Agenda. Moreover, in the last years, more and more consumers have shown a specific interest towards local production, pushed by the need for healthy eating, protecting the environment, and boosting the local economy. However, the cultivation of local fruit varieties or ecotypes has considerably decreased in the last decades because of their low production potential. As a result, many farmers have been forced to replace local orchards with few worldwide grown cultivars, causi…
