The projects that are coordinated and endorsed by the consortium fall within two broad categories: physical mapping (construction of physical maps for hexaploid wheat, Chinese spring, and for Ae. tauschii - the D-genome) and sequencing (the development of the resources necessary for sequencing and the testing of technologies to determine the best method for sequencing). A recent paper that discussed the IWGSC strategies and projects was published recently. The Israel Journal of Plant Sciences has kindly agreed to make it available for posting on the IWGSC website.

Funding has been secured for finishing the physical map of the Ae. tauschii genome (in the USA) and for the development of physical maps for 11 chromosomes of Chinese Spring (as indicated in the diagram below). Leaders for the other chromosomes have been identified and efforts are underway to develop and secure funding for physical mapping projects as well as for sequencng.

Satus of Physical Mapping Projects
Completed Projects
3B - Led by C. Feuillet (INRA, France), this has served as the pilot project for developing a physical map of a flow-sorted chromosome. An 9.6X chromosome landing ready physical map of chromosome 3B of Chinese spring was produced. Publication: Paux E, Sourdille P, Salse J et al. (2008) A physical map of the 1-gigabase bread wheat chromosome 3b. Science 322: 101-104.
Funded Projects
1A, 1B, 3D, (3Bv2) - TriticeaeGenome project EU Commission FP7 - Coordinated by C. Feuillet (INRA, France) with 17 EU partners, this European project will complete the physical maps of group 1 and 3 chromosomes in wheat (and barley). Map-based cloning of targeted QTL, molecular breeding and bioinformatics platforms will also be developed within the framework of this project.
2AL – Led by K. Singh (Punjab Agricultural University, India), this project for the construction of the physical map of the long arm of chromosome 2A of Chinese spring has been funded by the Department of Biotechnology, Ministry of Science and Technology, Government of India.
2D - Led by J. Jia (KL-CGB, CAAS, China) and funded by Chinese Academy of Agricultural Sciences, this project will develop a physical map of chromosome 2D of Chinese spring.
3AS/AL - Led by B. Gill (KSU, USA) and funded by the USDA (CSREES-NRI), these projects are developing anchored physical maps of the short and long-arms of chromosome 3A.
4A BAC Library construction – Led by J. Dolezel (Institute for Experimental Biology, Czech Republic), this project has resulted in the construction of a BAC library for 4A and funding is being sought for physiclal mapping.
5A - Led by L. Cattivelli (Experimental Institute for Cereal Research, Italy) and funded by the Agricultural Research Council of Italy to develop the physical map of chromosome 5A.
1,4,6 D of hexaploid and all of Ae. tauschii - "D-Genome project" - Led by J. Dvorak, B. Gill, and O. Anderson (UC-Davis, KSU, and USDA-ARS, respectively), this project, submitted to the US National Science Foundation, will complete the Ae. tauschii physical map and, subsequently, be used as a framework for developing physical maps of chromosomes 1,4, and 6 of the D genome of Chinese spring and all other D genome chromosomes of hexaploid wheat taken by other groups.
Status of IWGSC Sequencing Projects
Sequencing of Chromosomes: Funded Projects
C. Feuillet, (INRA France), Funding commited by the French Ministry of Higher Education and Research for sequencing chromosome 3B. Project goals and scope are under development and will include pilots on next generation sequencing technologies.
Sequencing of Megabase sized contigs on chromosome 3B
3AS Sample Sequencing project
Led by B. Gill (KSU, USA) and funded by the USDA (CSREES-NRI), this project will generate 18.4 Mb of sequence from the chromosome 3AS BAC libraries, sequence 48 targeted BAC clones, and BAC end sequence 10,000 random clones. The second sequencing component of this project is to compare the 3AS BAC sequences with sequences from homoeologous chromosome arm 3BS.
New generation sequencing technologies
A number of small projects are currently underway to evaluate the feasibility of using new sequencing technologies to accelerate marker development and reduce MTP sequencing cost while maintaining quality and without losing access to the non genic but yet relevant sequences.
IWGSC-IBSC Workshop on Sequencing Technologies
As a result of the significant progress that has been made towards physical mapping and the development of new sequencing technologies, the IWGSC was joined by the International Barley Sequencing Consortium in organizing a workshop on sequencing technolgies. The workshop was held 11-12 September 2008 at Genoscope and strategic roadmaps for sequencing the wheat and barley genomes were agreed upon. A white paper is under development.
