We report the development of microsatellites or simple sequence repeats (SSRs) in the olive tree (Olea europaea L.). Forty three positive clones obtained by the screening of a GA-enriched genomic library were sequenced and primers were designed for 13 microsatellite loci. Five primer pairs amplified polymorphic products of the expected size range. SSR(More)
Characterisation of plastid genome (or cpDNA) polymorphisms is commonly used for phylogeographic, population genetic and forensic analyses in plants, but detecting cpDNA variation is sometimes challenging, limiting the applications of such an approach. In the present study, we screened cpDNA polymorphism in the olive tree (Olea europaea L.) by sequencing(More)
One of the main limitations of cereal breeding is the lack of genetic variability within cultivated crops. Hordeum chilense is a wild relative of Hordeum vulgare, which has been successfully used in the synthesis of amphiploids by crossing with Triticum spp. Among the agronomic traits of these new amphiploids, the allelic variation in the endosperm storage(More)
A survey of Gramineae markers was carried out with the aim of developing cost-effective methods for the molecular analysis of Miscanthus species. Ten out of twenty Gramineae RFLP probes from ”anchor” sets hybridized well to Miscanthus DNA while all 15 maize probes tested cross-hybridized successfully, showing similar patterns in both species. Cross-taxa(More)
Wheat is the third most important crop for human nutrition in the world. The availability of high-resolution genetic and physical maps and ultimately a complete genome sequence holds great promise for breeding improved varieties to cope with increasing food demand under the conditions of changing global climate. However, the large size of the bread wheat(More)
Hordeum chilense, a native South American diploid wild barley, is a potential source of useful genes for cereal breeding. The use of this wild species to increase genetic variation in cereals will be greatly facilitated by marker-assisted selection. Different economically feasible approaches have been undertaken for this wild species with limited direct(More)
Multi-allelic microsatellite markers have become the markers of choice for the determination of genetic structure in plants. Synteny across cereals has allowed the cross-species and cross-genera transferability of SSR markers, which constitute a valuable and cost-effective tool for the genetic analysis and marker-assisted introgression of wild related(More)
Alternate bearing is a widespread phenomenon among crop plants, defined as the tendency of certain fruit trees to produce a high-yield crop one year ("on-year"), followed by a low-yield or even no crop the following year ("off-year"). Several factors may affect the balance between such developmental phase-transition processes. Among them are the microRNA(More)
RAPD markers generated by mixtures of two different primers were developed for octoploid × Tritordeum (amphiploid Hordeum chilense × Triticum aestivum) and its parents. Addition lines were used to identify 21 specific RAPD markers for the H. chilense chromosomes detectable in a wheat background. Ten RAPD bands were selected and eight of them were converted(More)
The transferability of microsatellite markers developed for olive cultivars (Olea europaea L.) has been tested and confirmed in the Olea complex. Thirty two genotypes, belonging to different taxa of the genus Olea, have been analyzed with four olive SSRs. Positive amplifications at all loci were obtained in 13 taxa (at least one accession per species).(More)
