TI  - Physical characterization of the homoeologous group 5 chromosomes of wheat in 
      terms of rice linkage blocks, and physical mapping of some important genes.
PG  - 191-8
AB  - The wheat homoeologous Group 5 chromosomes were characterized physically in terms 
      of rice linkage blocks using a deletion mapping approach. All three chromosomes, 
      5A, 5B, and 5D, were shown to have a similar structure, apart from the 4A-5A 
      translocation on the distal end of chromosome arm 5AL. The physical mapping of 
      rice markers on the deletion lines revealed that the whole of rice chromosome 9 
      is syntenous to a large block, proximal to the centromere, on the long arm. 
      Likewise, a small segment of the distal end of the long arm showed conserved 
      synteny with the distal one-third end of the long arm of rice chromosome 3. In 
      between those conserved regions, there is a region on the long arm of the Group 5 
      chromosomes which shows broken synteny. The proximal part of the short arms of 
      the Group 5 chromosomes showed conserved synteny with a segment of the short arm 
      of rice chromosome 11 and the distal ends showed conserved synteny with a segment 
      of rice chromosome 12. The physical locations of flowering time genes (Vrn and 
      earliness per se) and the gene for grain hardness (Ha) on the Group 5 chromosomes 
      were determined. These results indicate that comparative mapping using the 
      deletion mapping approach is useful in the study of genome relationships, the 
      physical location of genes, and can determine the appropriate gene cloning 
      strategy.
