| 英文摘要 | The roegneria of triticeae is a large genus including about 130 allopolyploid species. little is known about its high-molecular-weight glutenin subunits (hmw-gss). here, we reported six novel hmw-gs genes from r. nakaii and r. alashanica. sequencing indicated that rny1, rny3, and ray1 possessed intact open reading frames (orfs), whereas rny2, rny4, and ray2 harbored in-frame stop codons. all of the six genes possessed a similar primary structure to known hmw-gs, while showing some unique characteristics. their coding regions were significantly shorter than glu-1 genes in wheat. the amino acid sequences revealed that all of the six genes were intermediate towards the y-type. the phylogenetic analysis showed that the hmw-gss from species with st, sty, or sth genome(s) clustered in an independent clade, varying from the typical x- and y-type clusters. thus, the glu-1 locus in r. nakaii and r. alashanica is a very primitive glutenin locus across evolution. the six genes were phylogenetically split into two groups clustered to different clades, respectively, each of the two clades included the hmw-gss from species with st (diploid and tetraploid species), sty, and sth genomes. hence, it is concluded that the six roegneria hmw-gs genes are from two st genomes undergoing slight differentiation. |
