Figure 2.—

Schematic orthologous map of wheat consensus chromosome 1 ESTs with rice chromosomes 5 and 10. The wheat consensus chromosome 1 intervals are linked using lines with rice genetic maps in the locations where wheat ESTs are sequence matched with rice BAC/PAC clones. Order of the lines (ESTs) in wheat consensus chromosome 1 intervals was based on the order of homoeologous rice sequences (BAC/PAC clones). In the consensus bin map of wheat chromosome 1, the numbers and located intervals of wheat group 1 ESTs (lines) and the distance from the centromere (fraction length) are indicated. In the rice maps, the locations and numbers of BAC/PAC clones (lines linked with wheat map) and interval lengths (in centimorgans) are indicated. The arrows in rice chromosomes 5 and 10 indicate the approximate regions of centromere cited from http://www.gramene.org/. For those wheat ESTs not mapped to specific intervals, the chromosome (W1) or chromosome arms (W1S for the short and W1L for the long arm) are indicated. The specific map locations of three rice BAC/PAC clones on chromosome 5 are not available, and the corresponding wheat ESTs are thus linked with a code R5 in the figure. The details including accession numbers of wheat ESTs and rice BAC/PAC clones and the orthologous map of wheat group 1 ESTs are also presented as supplemental online materials at http://wheat.pw.usda.gov/pubs/2004/Genetics/.
