AB  - The genomes of five Agropyron Gaertner, 1770 species were characterized using all 
      potential di- or trinucleotide simple sequence repeat (SSR) motifs and four 
      satellite DNA repeats as fluorescence in situ hybridization (FISH) probes. The 
      sites of 5S and 45S rDNA were relatively conserved among the diploid and 
      tetraploid species. A number of sites for the dinucleotide SSRs AC, AG, and 
      pSc119.2 was detected in all investigated species except A. mongolicum Keng, 
      1938. Several different trinucleotide SSRs were identified in different 
      tetraploid species. All Agropyron species were suggested to include the basic P 
      genome, although genome differentiation was still observed. The P genome of A. 
      mongolicum was distinct from that of the diploid A. cristatum (Linnaeus, 1753) 
      Gaertner, 1770. and other tetraploid species, with no hybridizations for AC, AG, 
      or pSc119.2 observed. This finding supports designation of the P genomes of A. 
      cristatum and A. mongolicum as P(c) and P(m), respectively. An exceptional 5S 
      rDNA site revealed in one set of homoeologous chromosomes strongly supports the 
      allopolyploid origin of A. desertorum (Fischer ex Link, 1821) Schultes, 1824. 
      However, the diploid donors to A. desertorum need further investigation. 
      Similarly, the unique FISH pattern of a pair of 5S rDNA-carrying chromosomes was 
      indicative of a potential allopolyploid origin for A. fragile (Roth, 1800) 
      Candargy, 1984. The conserved distribution of 5S and 45S rDNA suggests A. 
      cristatum (4x) and A. michnoi Roshevitz, 1929 are closely related. Two forms of B 
      chromosomes were identified among individuals A. mongolicum and A. desertorum 
      plants.
