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 *** ITS showed the best species discrimination by resolving 23 of the species as exclusive lineages with no shared alleles between any of the 24 distinct species(*** and *** are not supported as distinct species based on our molecular and morphological data).Conversely,rbcL performed the worst and only resolved 10 of the species as exclusive lineages,and 10 species with shared *** ITS has the advantage of high PCR amplification success and it provides good intra-and interspecific variation distribution *** most powerful plastid markers were petD and trnH-psbA,but we could amplify and sequence trnH-psbA for only 83% of the accessions *** of ITS and petD performed extremely well,with all 24 of the distinct species resolved as exclusive lineages and no shared alleles between any of the distinct *** therefore recommend ITS,or a combination of ITS and petD,as the standard DNA barcode in Hedyotis,but acknowledge that there are no shared alleles between distinct species for matK and rbcL combined.
