Causes of the genetic architecture of south-west European high mountain disjuncts

2008

Background: Postglacial climatic warming in south-western Europe and the retreat of cold-adapted species into higher elevations, starting in the Sierra Nevada and proceeding northwards to the Pyrenees and Alps, should have resulted in a pattern of ‘successive vicariance’. Alternatively, long-distance dispersal might explain the extant distribution pattern of mountain species in this region. Aims: Here, we report an investigation of two alpine plants, Saxifraga oppositifolia and S. stellaris, which co-occur in the Sierra Nevada, the Pyrenees, and the south-western Alps/Massif Central. Our aim was to distinguish between (successive) vicariance and long-distance dispersal as alternative explan…

Development of “universal” gene-specific markers from Malus spp. cDNA sequences, their mapping and use in synteny studies within Rosaceae

2009

The Rosaceae contains many economically valuable crop genera, including Malus (apple), Fragaria (strawberry), and Prunus (stone fruit). There has been increasing interest in the development of linkage maps for these species, with a view to marker-assisted selection to assist breeding programs and, recently, in the development of transferable markers to permit syntenic comparisons of maps of different rosaceous genera. In this investigation, a set of Malus cDNA sequences were downloaded from the European Molecular Biology Laboratory database. The sequences were aligned with homologous full-length Arabidopsis genomic DNA sequences to identify putative intron–exon junctions and conserved flank…

The aroma of strawberry (Fragaria ananassa): Characterisation of some cultivars and influence of freezing

1990

The volatiles of six strawberry (Fragaria ananassa Duch) cultivars, both fresh and deep-frozen, were isolated by direct dichloromethane extraction. Sixty compounds were identified and quantified by GC—MS. Characterisation of cultivars was achieved by applying principal component analysis to the chromatographic data. Great differences were observed. Maxim and Directeur Paul Wallbaum are rather low in volatiles while Gariguette and Tioga are rich in mesifurane (2,5-dimethyl-4-methoxy-2,3-dihydrofuran-3-one), furaneol' (2,5-dimethyl-4-hydroxy-2,3-dihydrofuran-3-one) and nerolidol. Esters are the major compounds in Senga Sengana and Vicomtesse Hericart de Thury. This last cultivar is also chara…

Evaluation of strawberry cultivars in soilless cultivation in Sicily

Study on New Strawberry Varieties Evaluated in Sicily

2009

The variety evolution and growing techniques have modified the strawberry cultivation in the Italian Mediterranean areas. Different trials in Sicily showed that varietal choices are the base to reach high levels of quality and quantity production. In Sicily, 300 ha of strawberries are now cultivated and 'Tudla' is still the principal variety (60%), 'Camarosa' is the most cultivated variety in the other southern strawberry areas, but in Sicily this cultivar does not generate a great interest because of its lateness. New cultivars, such as 'Candonga', 'Ventana' and 'Naiad', have been trialled in the last years but further evaluations are necessary. The trial was carried out at the experimenta…

Monoclonal antibody-based immunoassays for cyprodinil residue analysis in QuEChERS-based fruit extracts

2015

Cyprodinil is among the most common agrochemical residues found in highly perishable fruits, such as strawberries. In the present study, high-affinity monoclonal antibodies to this anilinopyrimidine fungicide were raised for the first time with the aim to produce valuable immunochemical analytical assays. Cyprodinil bioconjugates and the generated novel monoclonal antibodies were employed for sensitive competitive immunoassay development in two different formats. The limits of detection of the optimized assays were 20 and 30 ng L-1 for the indirect and direct assay, respectively. Influence over assay parameters of different physicochemical factors was studied. Strawberry samples were extrac…

Vector Transmission of a Plant-Pathogenic Bacterium in the Arsenophonus Clade Sharing Ecological Traits with Facultative Insect Endosymbionts

2009

Bressan, A., Semetey, O., Arneodo, J., Lherminier, J., and BoudonPadieu, E. 2009. Vector transmission of a plant-pathogenic bacterium in the Arsenophonus clade sharing ecological traits with facultative insect endosymbionts. Phytopathology 99:1289-1296. The planthopper Pentastiridius leporinus (Hemiptera: Cixiidae) is the major vector of a nonculturable plant-pathogenic γ-3 proteobacterium associated with a disease of sugar beet called syndrome “basses richesses” (SBR). The bacterium, here called SBR bacterium, belongs to the Arsenophonous clade, which includes mostly insect-associated facultative symbionts. Assays using field-collected planthopper nymphs and adults were carried out to inve…
