AB  - As an important relative of wheat (Triticum aestivum L), Dasypyrum breviaristatum 
      contains novel high molecular weight glutenin subunits (HMW-GSs) encoded by 
      Glu-1Vb genes. We identified new wheat-D. breviaristatum chromosome introgression 
      lines including chromosomes 1V(b) and 1V(b)L.5V(b)L by fluorescence in situ 
      hybridization (FISH) combined with molecular markers. We found that chromosome 
      changes occurred in the wheat-D. breviaristatum introgression lines and 
      particularly induced the deletion of 5BS terminal repeats and formation of a new 
      type of 5B-7B reciprocal translocation. The results imply that the D. 
      breviaristatum chromosome 1V(b) may contain genes which induce chromosomal 
      recombination in wheat background. Ten putative high molecular weight glutenin 
      subunit (HMW-GS) genes from D. breviaristatum and wheat-D. breviaristatum 
      introgression lines were isolated. The lengths of the HMW-GS genes in Dasypyrum 
      were significantly shorter than typical HMW-GS of common wheat. A new y-type 
      HMW-GS gene, named Glu-Vb1y, was characterized in wheat-D. breviaristatum 1V(b) 
      introgression lines. The new wheat-D. breviaristatum germplasm displayed reduced 
      plant height, increased tillers and superior grain protein and gluten contents, 
      improved gluten performance index. The results showed considerable potential for 
      utilization of D. breviaristatum chromosome 1V(b) segments in future wheat 
      improvement.
