In the annual long-day plant Arabidopsis thaliana, suppressor of overexpression of constans1 (SOC1) integrates endogenous and environmental signals to promote flowering. We analyzed the function and regulation of the SOC1 homolog (Fragaria vesca [Fv] SOC1) in the perennial short-day plant woodland strawberry (Fragaria vesca). We found that Fv SOC1 overexpression represses flower initiation unde...

BACKGROUND Fragaria chiloensis (L.) Mill spp. chiloensis form chiloensis, is a strawberry that produces white fruits with unique aromas. This species, endemic to Chile, is one of the progenitors of Fragaria x ananassa Duch. In order to identify the volatile compounds that might be responsible for aroma, these were extracted, and analyzed by gas chromatography-mass spectrometry (GC-MS), gas chro...

Cultivated strawberry (Fragaria × ananassa Duch.) is one of the most important berry crops worldwide. Its wild relative, woodland strawberry (Fragaria vesca L.) is also scientifically important, since recent development of molecular tools including genetic transformation methods, genetic maps and genome sequence is making it as one of the leading perennial model plants. Environmental regulation...

BACKGROUND This study evaluated the effect of the solvent on the extraction of antioxidant compounds from black mulberry (Morus nigra), blackberry (Rubus ulmifolius) and strawberry (Fragaria x ananassa). Different extracts of each berry were evaluated from the determination of total phenolic content, anthocyanin content and antioxidant capacity, and data were applied to the principal component ...

Extending the period of fruit production is a way to substantially increase crop yield in many fruit or ornamental species. In the cultivated octoploid strawberry (Fragaria × ananassa), the most consumed small fruit worldwide, fruit production season can be extended by selecting the perpetual flowering (PF) cultivars. This trait is of considerable interest to growers and to the food industry. F...

A vast number of clones carrying cDNAs from genes differentially expressed along the strawberry (Fragaria x ananassa c.v. Chandler) fruit ripening process has been isolated by screening of a subtractive cDNA library. The library was constructed and screened using a powerful procedure that combines the differential screening technique with a Southern blot screening by means of the polymerase cha...
