简介
We present SSR-based genetic maps from a cross between Miscanthus sacchariflorus Robustus and M. sinensis, the progenitors of the promising cellulosic biofuel feedstock Miscanthus × giganteus. cDNA-derived SSR markers were mapped by the two-way pseudo-testcross model due to the high heterozygosity of each parental species. A total of 261 loci were mapped in M. sacchariflorus, spanning 40 linkage groups and 1,998.8 cM, covering an estimated 72.7% of the genome. For M. sinensis, a total of 303 loci were mapped, forming 23 linkage groups and 2,238.3 cM, covering 84.9% of the genome. The use of cDNA-derived SSR loci permitted alignment of the Miscanthus linkage groups to the sorghum chromosomes, revealing a whole genome duplication affecting the Miscanthus lineage after the divergence of subtribes Sorghinae and Saccharinae, as well as traces of the pan-cereal whole genome …
