Application of DNA barcodes in Hedyotis L. (Spermacoceae, Rubiaceae) [PDF]

Journal of Systematics and Evolution, 2011
Abstract  The potential application of DNA barcodes of plastid (matK, trnH–psbA, petD, and rbcL) and nuclear (internal transcribed spacer (ITS) of rDNA) DNA regions was investigated for 25 Hedyotis taxa. The ITS showed the best species discrimination by resolving 23 of the species as exclusive lineages with no shared alleles between any of the 24 ...
