Abstract:
Objective Application of a new molecular marker to the identification of Dendrobium (Orchidaceae) species. Methods Complete sequences of the mitochondrial nad 1 intron 2 for nine species of Dendrobium Sw. were amplified and determined. Results Seventeen variable sites were found in the aligned 872 bp of nad 1 intron 2 sequences. Eight of the nine Dendrobium species except D. loddigesii could be identified by the nad 1 intron 2 sequences. Conclusion The mitochondrial nad 1 intron 2 sequences could be used as a new molecular marker for the identification of Dendrobium species.
