AB  - Genomes of ten species of Elymus, either presumed or known as tetraploid StY, 
      were characterized using fluorescence in situ hybridization (FISH) and genomic in 
      situ hybridization (GISH). These tetraploid species could be grouped into three 
      categories. Type I included StY genome reported species-Roegneria pendulina, R. 
      nutans, R. glaberrima, R. ciliaris, and Elymus nevskii, and StY genome presumed 
      species-R. sinica, R. breviglumis, and R. dura, whose genome could be separated 
      into two sets based on different GISH intensities. Type I genome constitution was 
      deemed as putative StY. The St genome were mainly characterized with intense 
      hybridization with pAs1, fewer AAG sites, and linked distribution of 5S rDNA and 
      18S-26S rDNA, while the Y genome with less intense hybridization with pAs1, more 
      varied AAG sites, and isolated distribution of 5S rDNA and 18S-26S rDNA. 
      Nevertheless, further genomic variations were detected among the different StY 
      species. Type II included E. alashanicus, whose genome could be easily separated 
      based on GISH pattern. FISH and GISH patterns suggested that E. alashanicus 
      comprised a modified St genome and an unknown genome. Type III included E. 
      longearistatus, whose genome could not be separated by GISH and was designated as 
      St(l)Y(l). Notably, a close relationship between S(l) and Y(l) genomes was 
      observed.
