PHYLOGENY AND DISJUNCTION IN ROSCOEA (ZIGIBERACEAE)

摘要

A phylogenetic of Roscoea(Zingiberaceae), a high-altitude genus of an otherwise tropical plant family, was undertaken using sequence data from the internal transcribed spacers(ITS)of the nuclear ribosomal DNA(nrDNA). Two species off Cautley and two species of Curcuma were used as outgroups. This resulted in an Aligned matrix of 436bp(ITS1, 203bp; ITS2, 233bp).
