A complex mixture of hundreds of substances determines strawberry (Fragaria x ananassa) aroma, but only approximately 15 volatiles are considered as key flavour compounds. Of these, 4-hydroxy-2,5-dimethyl-3(2H)-furanone (HDMF) is regarded as the most important, but it is methylated further by FaOMT (Fragaria x ananassa O-methyltransferase) to 2,5-dimethyl-4-methoxy-3(2H)-furanone (DMMF) during ...

We genotyped strawberry cultivars by two newly selected and two previously reported SSR markers. All four markers produced interpretable electropherograms from 75 accessions consisting of 72 Fragaria × ananassa cultivars or lines and three octoploid Fragaria species accessions. These SSR markers were highly polymorphic; in particular, one of the newly developed markers, FxaHGA02P13, was capable...

In addition to the role of the cell wall as a physical barrier against pathogens, some of its constituents, such as pectin-derived oligogalacturonides (OGA), are essential components for elicitation of defence responses. To investigate how modifications of pectin alter defence responses, we expressed the fruit-specific Fragaria x ananassa pectin methyl esterase FaPE1 in the wild strawberry Frag...

Potential events of allopolyploidy may be indicated by incongruences between separate phylogenies based on plastid and nuclear gene sequences. We sequenced two plastid regions and two nuclear ribosomal regions for 34 ingroup taxa in Fragariinae (Rosaceae), and six outgroup taxa. We found five well supported incongruences that might indicate allopolyploidy events. The incongruences involved Apha...

Effect of Humic Acid, Arginine and Different Levels Vermicompost on Quantitative Qualitative Characteristics Strawberry (Fragaria × ananassa L. cv. Gaviota)

background & aim: strawberry (fragaria vesca l.) is a plant belonging to the rosaceae family with medicinal properties, including antioxidant activity. the present study aimed at investigating the antioxidant properties of strawberry. experimental method: to examine the antioxidant effect, fruit extracts at two phonological stages of growth (ripe and unripe strawberry) were prepared. in add...

The transmission of transgenes (uid-A and nptII) was studied in crosses between transgenic plants, with Fragaria x ananassa cultivar Teodora as the donor plant and various Fragaria species as recipient plants. GUS expression and kanamycin resistance were evaluated in embryos and in seedlings after aseptical germination, both in intraand inter-specific crosses as demonstrated by different ploidy...
