The International Strawberry Sequencing Consortium reports the draft genome of woodland strawberry (Fragaria vesca). this diploid species should serve as a reference for Fragaria genus, cultivated × ananassa) is an octoploid where F. vesca predicted to be subgenome donor. strawberry, (2n = 2x 14), versatile experimental plant system. This diminutive herbaceous perennial has small (240 Mb), amenable genetic transformation and shares substantial sequence identity with other economically...
Summary Flowering is a key event in plant life, and finely tuned by environmental endogenous signals to adapt different environments. In horticulture, continuous flowering (CF) popular trait introduced wide range of cultivated varieties. It played an essential role the tremendous success modern roses woodland strawberries gardens. CF genotypes flower during all favourable seasons, whereas once‐flowering (OF) only spring. Here we show that rose strawberry controlled orthologous genes TERMINAL...
A high-throughput genotyping platform is needed to enable marker-assisted breeding in the allo-octoploid cultivated strawberry Fragaria × ananassa. Short-read sequences from one diploid and 19 octoploid accessions were aligned vesca 'Hawaii 4' reference genome identify single nucleotide polymorphisms (SNPs) indels for incorporation into a 90 K Affymetrix® Axiom® array. We report development preliminary evaluation of this About 36 million sequence variants identified member, germplasm panel....
Macrosynteny and colinearity between Fragaria (strawberry) species showing extreme levels of ploidy have been studied through comparative genetic mapping the octoploid cultivated strawberry (F. xananassa) its diploid relatives. A comprehensive map strawberry, in which almost all linkage groups are ranged into seven expected homoeologous was obtained, thus providing first reference for Fragaria. High conserved macrosynteny were observed homo(eo)logous their corresponding groups. These results...
Abstract Plant phenolics have drawn increasing attention due to their potential nutritional benefits. Although the basic reactions of biosynthetic pathways in plants been intensively analyzed, regulation accumulation and flux through pathway is not that well established. The aim this study was use a strawberry (Fragaria × ananassa) microarray investigate gene expression patterns associated with phenylpropanoids, flavonoids, anthocyanins fruit. An examination transcriptome, coupled metabolite...
Asexual and sexual reproduction occur jointly in many angiosperms. Stolons (elongated stems) are used for asexual the crop species potato (Solanum tuberosum) strawberry (Fragaria spp), where they produce tubers clonal plants, respectively. In strawberry, stolon production is essential vegetative propagation at expense of fruit yield, but underlying molecular mechanisms unknown. Here, we show that deficiency trait runnerless (r) natural mutant woodland diploid vesca) due to a deletion active...
Cultivated strawberry (Fragaria × ananassa) is a genetically complex allo-octoploid crop with 28 pairs of chromosomes (2n = 8x 56) for which genome sequence not yet available. The diploid Fragaria vesca considered the donor species one octoploid sub-genomes and its available can be used as reference genomic studies. A wide number cultivars are stored in ex situ germplasm collections world-wide but previous studies have addressed genetic diversity present within limited these collections....
Metabolic profiling by 1-dimensional (1-D) 1H-nuclear magnetic resonance (NMR) was tested for absolute quantification of soluble sugars, organic acids, amino acids and some secondary metabolites in fruit, roots leaves. The metabolite responsible each peak the 1H-NMR spectra identified from pure compounds. Peak identity confirmed addition a small amount commercially-available substance. acquisition automated. performed with synthesised electronic reference signal validated comparison...
Fruit quality traits are major breeding targets in the Rosaceae. Several of Rosaceae species current or ancient polyploids. To dissect inheritance fruit polyploid fleshy species, we used a cultivated strawberry segregating population comprising 213 full-sibling F1 progeny from cross between variety 'Capitola' and genotype 'CF1116'. We previously developed most comprehensive linkage map, which displays seven homoeology groups (HG), including each four (Genetics 179:2045–2060, 2008). The map...
Strawberry (Fragaria sp.) stands as an interesting model for studying flowering behaviour and its relationship with asexual plant reproduction in polycarpic perennial plants. produces both inflorescences stolons (also called runners), which are lateral stems growing at the soil surface producing new clone In this study, runnering of two cultivated octoploid strawberry (Fragaria×ananassa Duch., 2n=8×=56) genotypes, a seasonal genotype CF1116 perpetual Capitola, were studied along season. The...
Summary Environmental stresses can result in a wide range of physiological and molecular responses plants. These also impact epigenetic information genomes, especially at the level DNA methylation (5-methylcytosine). is hallmark heritable modification plays key role silencing transposable elements (TEs). Although an essential mechanism, fundamental aspects its contribution to stress adaptation remain obscure. We investigated epigenome dynamics wild strawberry (Fragaria vesca) response...
Abstract Background In plants, epigenetic stress memory has so far been found to be largely transient. Here, we wanted assess the heritability of heat stress-induced and transcriptomic changes following woodland strawberry ( Fragaria vesca ) reproduction. Strawberry is an ideal model study inheritance because it presents two modes reproduction: sexual (self-pollinated plants) asexual (clonally propagated plants named daughter plants). Taking advantage this model, investigated whether DNA...
As genetic factors affect strawberry ( Fragaria ×ananassa Duch.) fruit development and quality, changes in metabolite concentrations were studied during of four cultivars grown the field: three commercial (Capitola, Elsanta Dover) a genotype from Centre Interrégional de Recherche et d'Expérimentation la Fraise, France (`CF1116'). Major minor metabolites changed with development. The two highest starch content at early stages, `Capitola' `Elsanta', also had weight harvest. There was no...
This study reports for the first time identification and characterization of Colletotrichum spp. anthracnose isolates originating from strawberry grown in France. Sixteen French six North American (also strawberry) representing C. acutatum, gloeosporioides, fragariae were compared with respect to morphological cultural criteria. Fourteen identified as characterized by acute conidia low growth rates. The remaining two gloeosporioides (teleomorph, Glomerella cingulata), cylindrical conidia,...
The cultivated strawberry (Fragaria×ananassa) is consumed worldwide for its flavor and nutritional benefits. Genetic analysis of commercially important traits in are the development breeding methods tools this species. Although several quantitative trait loci (QTL) have been previously detected fruit quality flowering using low-density genetic maps, clarity on sub-genomic locations these QTLs was missing. Recent discoveries allo-octoploid genomics led to IStraw90 single-nucleotide...
The Axiom® IStraw90 SNP (single nucleotide polymorphism) array was developed to enable high-throughput genotyping in allo-octoploid cultivated strawberry (Fragaria ×ananassa). However, high cost ($ 80-105 sample-1) limits throughput for certain applications. On average the has yielded 50 60% usable data points, defined as PHR (Poly High Resolution) and NMH (No Minor Homozygote) marker classes. Thus, an is needed with a higher percentage of points at lower cost. We initiated effort identify...
