基于形态性状及Adh1基因序列的芒与五节芒自然杂交现象研究
Natural hybridization between Miscanthus sinensis and M.floridulus revealed by phylogenic analysis using morphological traits and Adhl sequences
摘要
Abstract
Phylogenic analyses based on the morphological characters and Adhl 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 Adhl 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 Adhl 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.关键词
