Expanding the technology base for Norwegian wheat breeding; Sequencing wheat chromosome 7B.

Ane Gro Siri Skjelfjord

This project represents the first Norwegian participation in an international genomics program for agricultural plants.

Prosjektleder: Sigbjørn Lien

The main research objective of this proposal is to sequence wheat chromosome 7B as part of the Internatinal Wheat Genome Sequencing Consortium (IWGSC) effort to sequence the genome of bread wheat. In order to achieve this goal, we will construct and anchor to the genetic map, a physical map of the chromosome 7B of Chinese Spring (Research Task 1). This will be done by first constructing BAC libraries for each of the two chromosome arms 7Bs and 7BL, then assemble these into contigs representing the order of DNA segments in the chromosome arms. Bioinformatics tools will be used to structure, relate and comprehensively analyze the large scale genomics data. Databases for data archival, management and dissemination, tools for genomic sequence analysis, and an integrative database for the display of genetic and physical maps linked to markers, traits and phenotypes will be developed based on the existing CIGENE infrastructure. Data will be integrated with the EU-wide TriticeaeGenome bioinformatics platform and other lWGSC bioinformatics efforts and will be linked to established international cereal bioinformatics platforms such as Gramene. These assemblies will then be sequenced to produce a genomic sequence of 7B (Research Task 2). These activities are at the international forefront of plant genomics, and will position Norway as a member of the leading group in plant genome research. In addition to sequencing, the project aims at developing a comprehensive set of molecular markers for Graminor’s wheat breeding program (Research task 3). As outlined above these markers will be designed based on the resequencing of Norwegian wheat breeding materials based on the genomic sequence from the entire IWGSC project.
