Table 5 Analysis of 52 species from Data Set II. Inter-specific K2P distances and per cent species resolution of different loci from chloroplast genome using downloaded as well as self generated sequences for 52 Dendrobium species for which sequences of all the four loci (matK, rbcL, rpoB and rpoC1) were present

From: The loci recommended as universal barcodes for plants on the basis of floristic studies may not work with congeneric species as exemplified by DNA barcoding of Dendrobium species
