SEVEN

Structure and Evolution of the Wheat Genome

21chr

The objectives of the team SEVEN are:

  • To study the organisation and evolution of the wheat genome in order to better understand the relationships between genome structure, epigenome, gene expression, and evolutionary dynamics
  • To develop new genomic tools for wheat improvement

Our scientific project is based on the production of unique genomic resources of main interest for the community:

  • Reference sequence of chromosome 3B published in 2014 (Choulet et al. Science 2014)
  • Reference sequence of chromosomes 1B and 4B under production at Genoscope (FranceGenomique project WheatSeq)
  • Resequencing data of chromosome 3B from different wheat varieties and from other Triticeae species
  • Draftsequence assemblies of the 21 chromosomes produced in the framework of the IWGSC (IWGSC Science 2014)
  • SNP markers covering the entire hexaploid genome
  • Bioinformatics tools and database for sequence and data analyses
