BACKGROUND Among next generation sequence technologies, platforms such as Illumina and SOLiD produce short reads but with higher coverage and lower cost per sequenced nucleotide than 454 or Sanger. A challenge now is to develop efficient strategies to use short-read length platforms for de novo assembly and marker development. The scope of this study was to(More)
Carrot is the most economically important member of the Apiaceae family and a major source of provitamin A carotenoids in the human diet. However, carrot molecular resources are relatively underdeveloped, hampering a number of genetic studies. Here, we report on the synthesis and characterization of a bacterial artificial chromosome (BAC) library of carrot.(More)
UNLABELLED PREMISE OF THE STUDY Analyses of genetic structure and phylogenetic relationships illuminate the origin and domestication of modern crops. Despite being an important worldwide vegetable, the genetic structure and domestication of carrot (Daucus carota) is poorly understood. We provide the first such study using a large data set of molecular(More)
Polymorphism of simple sequence repeat (SSR) loci was assessed in a collection of 88 carrot (Daucus carota L. subsp. sativus Hoffm.) accessions. The collection comprised cultivars and landraces mainly from Asia, Europe, and North America. Plants were grown in the glasshouse and characterized for root color and shape. Thirty SSR loci were fully characterized(More)
We report a high-quality chromosome-scale assembly and analysis of the carrot (Daucus carota) genome, the first sequenced genome to include a comparative evolutionary analysis among members of the euasterid II clade. We characterized two new polyploidization events, both occurring after the divergence of carrot from members of the Asterales order,(More)
Human manipulation of wild progenitors during crop domes-tication has led to the foundation of modern agriculture (Zohary and Hopf, 2000 ; Glémin and Bataillon, 2009). A common suite of traits including loss of seed shattering, dormancy, and branching are often selected during the domestication process and referred to as the " domestication syndrome "(More)
Sequence analysis of organelle genomes has revealed important aspects of plant cell evolution. The scope of this study was to develop an approach for de novo assembly of the carrot mitochondrial genome using next generation sequence data from total genomic DNA. Sequencing data from a carrot 454 whole genome library were used to develop a de novo assembly of(More)
A linkage map of carrot (Daucus carota L.) was developed in order to study reproductive traits. The F2 mapping population derived from an initial cross between a yellow leaf (yel) chlorophyll mutant and a compressed lamina (cola) mutant with unique flower defects of the sporophytic parts of male and female organs. The genetic map has a total length of 781(More)
Miniature inverted-repeat transposable elements (MITEs) are small and high copy number transposons, related to and mobilized by some class II autonomous elements. New MITE families can be identified by computer-based mining of sequenced genomes. We describe four MITE families related to MtPH transposons mined de novo in the genome of Medicago truncatula,(More)
Carrot is one of the most economically important vegetables worldwide, but genetic and genomic resources supporting carrot breeding remain limited. We developed a Diversity Arrays Technology (DArT) platform for wild and cultivated carrot and used it to investigate genetic diversity and to develop a saturated genetic linkage map of carrot. We analyzed a set(More)
