| genetic variation and species identification of thai boesenbergia (zingiberaceae) analyzed by chloroplast dna polymorphism. | genetic variation and molecular phylogeny of 22 taxa representing 14 extant species and 3 unidentified taxa of boesenbergia in thailand and four outgroup species (cornukaempferia aurantiflora, hedychium biflorum, kaempferia parviflora, and scaphochlamys rubescens) were examined by sequencing of 3 chloroplast (cp) dna regions (matk, psba-trnh and peta-psbj). low interspecific genetic divergence (0.25-1.74%) were observed in these investigated taxa. the 50% majority-rule consensus tree constructed ... | 2006 | 16889678 |
