Population structure of Miscanthus sacchariflorus reveals two major polyploidization events tetraploid-mediated unidirectional introgression from diploid M. sinensis and diversity centred around the Yellow Sea

摘要

Miscanthus, a C4 perennial grass native to East Asia, is a promising biomass crop. Miscanthus sacchariflorus has a broad geographic range, is used to produce paper in China and is one of the parents (along with Miscanthus sinensis) of the important biomass species Miscanthus × giganteus. The largest study of M. sacchariflorus population genetics to date is reported here.
