Macrosynteny and colinearity between Fragaria (strawberry) species showing extreme levels of ploidy have been studied through comparative genetic mapping between the octoploid cultivated strawberry (F. xananassa) and its diploid relatives. A comprehensive map of the octoploid strawberry, in which almost all linkage groups are ranged into the seven expected homoeologous groups was obtained, thus...

Strawberry tree fruits (Arbutus unedo L.) are a natural source of valuable biologically active compounds. Therefore, the aim this work was to develop green extraction approach using pressurized liquid (PLE) provide highest yield bioactive Different solvents (distilled water, 50% and 96% ethanol) different PLE parameters were investigated: temperature (40, 80, 120 °C), static time (5 10 min), nu...

Many insect and fungal pathogens posing agronomically important threats specifically target the roots in strawberry. The use of a root-specific promoter to confer expressionof resistancegenes in a targetedmanner has the potential appreciably to benefit the genetic improvement of commercial strawberry varieties. A novel gene, FaRB7, was isolated from strawberry (Fragaria3 ananassa Duch.) and fou...

Strawberry (Fragaria spp) is an emerging model for the development of basic genomics and recombinant DNA studies among rosaceous crops. Functional genomic and molecular studies involve relative quantification of gene expression under experimental conditions of interest. Accuracy and reliability are dependent upon the choice of an optimal reference control transcript. There is no information ava...

abstract silicon (si) is considered one of the beneficial elements for plant, however recent studies show that si plays an important role in plant resistance to environmental stresses , like salinity. an experiment was conducted to study the effect of si and nacl salinity on the growth, yield and fruit quality of strawberry (fragaria × ananassa duch) cv “selva” was grown hydroponically in the c...

Arbutus andrachne L., the strawberry tree, is an evergreen shrub or small tree in Turkish flora and has broad uses. The wood used for decorative purposes, packaging, manufacturing furniture. fruits are edible treating many kinds of diseases. However, global warming might affect abundance this symbolic plant's distribution, especially at higher latitudes. This study was conducted to determine ex...

The effects of elevated CO2 concentrations on the antioxidant capacity and flavonoid content in strawberry fruit (Fragaria x ananassa Duch.) were studied under field conditions. Increased CO(2) (300 and 600 micromol mol(-1) above ambient) concentrations resulted in increases in ascorbic acid (AsA), glutathione (GSH), and ratios of AsA to dehydroascorbic acid (DHAsA) and GSH to oxidized glutathi...

ABSTRACT Marginal chlorosis has affected strawberry production in France for about 15 years. A phloem-restricted uncultured bacterium, "Candidatus Phlomobacter fragariae," is associated with the disease. A large-scale survey for marginal chlorosis in French strawberry production fields and nurseries by polymerase chain reaction amplification of "Ca. P. fragariae" 16S rDNA revealed that symptoms...

Aims: This study was designed to evaluate the antibacterial and antioxidant activities of methanolic, ethanolic, ethyl acetate and n-hexanic extract from the leaves of Strawberry tree (Arbutus unedo L.) growing in Morocco. Study Design: Determination of total phenol and flavonoids content, in vitro antioxidant activity and antibacterial study of extracts. Place and Duration of Study: Department...
