The PR10 family protein Fra a 1E from strawberry (Fragaria x ananassa) is down-regulated in white strawberry mutants, and transient RNAi (RNA interference)-mediated silencing experiments confirmed that Fra a 1 is involved in fruit pigment synthesis. In the present study, we determined the solution structure of Fra a 1E. The protein fold is identical with that of other members of the PR10 protei...

Strawberry (Fragaria x ananassa Duch.) production in Florida is the second largest in the U.S. after California, with about 3360 hectares and gross sales over $330 million. Florida is the largest supplier of strawberries during the winter months in the U.S. and the majority of the strawberry production occurs in the west central part of the state. Strawberry yields in Florida have increased ove...

The difference in the phenotypes characters gene expressionof is influenced by changes hormone signaling mechanisms to receptors due adaptation various ty...

Genotyping-by-sequencing (GBS) was used to survey genome-wide single-nucleotide polymorphisms (SNPs) in three biparental strawberry (Fragaria × ananassa) populations with the goal of evaluating this technique in a species with a complex octoploid genome. GBS sequence data were aligned to the F. vesca 'Fvb' reference genome in order to call SNPs. Numbers of polymorphic SNPs per population ranged...

BACKGROUND AND AIMS Experimental crosses between the diploid woodland strawberry (Fragaria vesca L.) and the octoploid garden strawberry (F. × ananassa Duch.) can lead to the formation of viable hybrids. However, the extent of such hybrid formation under natural conditions is unknown, but is of fundamental interest and importance in the light of the potential future cultivation of transgenic st...

This study evaluated the phenolic profile and antioxidant capacity of strawberries (Fragaria x ananassa Duch., cv. Primoris) cultivated under reduction nitrogen adverse irrigation conditions (high salinity), such as those prevailing in Almeria (south-eastern Spain). The compound anthocyanin profiles were analysed by HPLC-DAD-ESI/MSn, activity. Nineteen compounds quantified, mainly ellagitannins...

The strawberry (Fragaria x ananassa) FaGAST gene encodes a small protein with 12 cysteine residues conserved in the C-terminal region similar to a group of proteins identified in other species with diverse assigned functions such as cell division, elongation, or elongation arrest. This gene is expressed in the fruit receptacle, with two peaks during ripening at the white and the red-ripe stages...

A cDNA clone encoding a putative dihydroflavonol 4-reductase gene has been isolated from a strawberry (Fragaria x ananassa cv Chandler) DNA subtractive library. Northern analysis showed that the corresponding gene is predominantly expressed in fruit, where it is first detected during elongation (green stages) and then declines and sharply increases when the initial fruit ripening events occur, ...

the objective of the present study is to investigate the impact of spraying boric acid on vegetative and reproductive growth of ‘camarosa’ strawberry (fragaria × ananassa duch.). the strawberry plants were sprayed with boric acid at 0 (control), 50 and 100 mg l-1 at 30 days after planting. in general, results indicated that spraying plants with boric acid had a significant effect on yield, frui...

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...
