Plants have several L-ascorbic acid (AsA) biosynthetic pathways, but the contribution of each one to the synthesis of AsA varyies between different species, organs, and developmental stages. Strawberry (Fragaria×ananassa) fruits are rich in AsA. The pathway that uses D-galacturonate as the initial substrate is functional in ripe fruits, but the contribution of other pathways to AsA biosynthesis...

The relative susceptibility of 44 genotypes of wild Fragaria L. and commercial cultivars of strawberry Fragaria ×ananassa Duch. to Meloidogyne hapla Chitwood and Pratylenchus penetrans (Cobb) Filipjev & Shuurmans Stekhoven was evaluated in the greenhouse. Eleven genotypes were highly resistant to populations of M. hapla from Washington State and Oregon, with Rf values (initial nematode density/...

Prospection of the endosphere native plant Fragaria chiloensis subsp. f. patagonica from foothills Chilean Andes led to isolation two strains genus Coniochaeta. We addressed taxonomic placement these based on DNA sequencing data using ITS and LSU genetic markers, morphological features, biochemical traits. One was identified as Coniochaeta hansenii, for which anamorph teleomorph states were des...

Cultivated strawberry (Fragaria × ananassa) is a genetically complex allo-octoploid crop with 28 pairs of chromosomes (2n = 8x = 56) for which a genome sequence is not yet available. The diploid Fragaria vesca is considered the donor species of one of the octoploid sub-genomes and its available genome sequence can be used as a reference for genomic studies. A wide number of strawberry cultivars...

Aroma and flavor are important factors of fruit quality and consumer preference. The specific pattern of aroma is generated during ripening by the accumulation of volatiles compounds, which are mainly esters. Alcohol acyltransferase (AAT) (EC 2.3.1.84) catalyzes the esterification reaction of aliphatic and aromatic alcohols and acyl-CoA into esters in fruits and flowers. In Fragaria x ananassa,...

the flowering and fructification period of the chilean strawberry (fragaria chiloensis (l.) duch.) is restricted to approximately 2 mo, which seriously limits the commercial development of the species. the objective of the current investigation was to identify inter simple sequence repeat (issr) polymorphisms associated with flowering duration in accessions of f. chiloensis. the flowering durat...
