Fig. 7From: Phylogenetic analysis and development of molecular markers for five medicinal Alpinia species based on complete plastome sequencesThe gel electrophoresis results of the amplification of DNA barcodes using designed primers. Lane M was the marker of DL1000. The lanes from left to right corresponded to products amplificated from the first individual of A. galanga, A. hainanensis, A. nigra, A. officinarum, and A. oxyphylla by primer Alpp and Alpr, respectively.
