Goals of the coordination group are:


1. To collect all information on Triticeae large insert libraries.

2. To provide as much as possible information on the WEB.

3. To give an account of the worldwide activities in the area of map-based cloning and physical mapping.

Goal 2. WEB-based information


http://agronomy.ucdavis.edu/Dubcovsky/BAC-library/ITMIbac/ITMIBAC.htm

(summary page with large number of web links to the individual libraries)


http://www.genome.clemson.edu/

(CUGI home page - distribute numbers of BAC filters and clones)


http://barleygenomics.wsu.edu

(Mapping of ESTs and cDNAs onto BAC clones)






Goal 3. Account of activities


1. USA barley community trying to secure NSF funding for barley genome physical mapping (Kleinhofs, Muehlbauer)

2. On going attempt to secure additional fund (NSF) to develop additional Triticeae BAC libraries (Dvorak et al.) including Morex (2 other enzymes) and T. spontaneum.

3. Mapping of 1200 ESTs and cDNAs on barley BACs (Kleinhofs et al.)

4. BAC contig of chromosome 1 (7H) 30cM region (Kleinhofs)

5. Map-based cloning of scald (7H) (Roeder)

6. Map-based cloning of BaYMV (3H) (Graner)

7. Map-based cloning of dwarfing gene (2H) (Graner)

8. Mapping 500-800 ESTs (Altschmied)

9. Map-based cloning for genes involved in flower and leaf development (Salamini)

10. Mapping of the Glu-1 and Glu-3 loci in wheat (USA)

11. Physical mapping of chromosome 1 group (USA)

Correction: Physical mapping of the D-genome
