Natural hybridization between Miscanthus sinensis and M. floridulus revealed by phylogenic analysis using morphological traits and Adh1 sequences

Abstract

Abstract: Phylogenic analyses based on the morphological characters and Adh1 gene sequences were carried out to identify natural hybridization between Miscanthus sinensis and M. floridulus. One putative hybrid (AD431) clustered together with M. floridulus samples and other putative hybrids (AD623, AD512, AD620, AD619 and AD627) grouped with M. sinensis samples. However, two divergent types of Adh1 gene sequences were observed in all samples of putative hybrids, one of which clustered with M. sinensis while the other clustered with M. floridulus on the Adh1 phylogeny, suggesting that they are true hybrids between M. sinensis and M. floridulus. This study provides a basis for further research on genetic relationship between the two Miscanthus species.
