The Research Developments of DNA Sequence in Identification of DendrobiumSpecies / 世界科学技术-中医药现代化

ABSTRACT

This paper reviewed the research developments of identification and classification ofDendrobium species based on DNA sequences from nuclear genome, mitochondrial genome and chloroplast genome. The existing documents revealed that DNA sequences used in identification ofDendrobium mainly include ITS/ITS2,LEAFY, chloroplastrbcL, matK, trnH-psbA, rpoB, rpoC1, trnL-F, rbl16, trnl intron, and mtDNA, nad1 intron2. These DNA sequences had the reference meanings in the identification ofDendrobium species. This article discussed the feasibility of complete chloroplast genome as the“super-barcode”, which provided the references for identification of medicinal plants inDendrobium.
