Composite linkage
map, based on 4,700 markers from 20 international maps, has been compiled.
Markers on the map are linked electronically to the Catalog of Gene Symbols
for Wheat.
Individual genetic maps are available in cMAP format through an internet
interface. |
- A total of 500,000
ESTs (at least 35,000 contigs, 46,000 singletons) are recorded and
approximately 6,000 are assigned to 159 bins across the 21 wheat chromosomes
based on deletion and ditelsomic stocks.
- 200,000 BAC
clones arranged as contigs across the entire D-genome donor of hexaploid
wheat. Approximately 1,000 ESTs assigned to BAC clones.
- Domesticated
einkorn BAC library studied in detail in rust and vernalization regions
of the genome.
- 200,000 BAC
clones of the hexaploid wheat Å-genome donor T. urartu.
