THE PHYLOGENY OF TRIBE ZINGIBEREAE (ZINGIBERACEAE) BASED ON ITS (nrDNA) AND trnL–F (cpDNA) SEQUENCES

Abstract

A phylogenetic analysis of the tribe Zingibereae (Zingiberaceae) was performed using nuclear ribosomal DNA (ITS1, 5.8S and ITS2) and chloroplast DNA (trnL (UAA) 5p exon to trnF (GAA)). The tribe is monophyletic with two major clades, the Curcuma clade and the Hedychium clade. Paracautleya, sampled for the first time, comes out as predicted while Caulokaempferia comes out in a different position from that found in another recent study. The genera Boesenbergia and Curcuma are apparently not monophyletic.

Curcuma woodii (Zingiberaceae), a new species from Thailand

“…Ecomata (see Figure 3 in this paper, Figure 2 in Chen et al 2015: 344). The phylogeny study also supported that Curcuma and Curcuma-like genera were paraphyletic, which was in conjunction with earlier investigations (Kress et al 2002, Ngamriabsakul et al 2004, Záveská et al 2012. Based on the molecular phylogeny study of Curcuma, Zaveska et al (2012) suggested Curcuma-like genera must be transferred to the genus Curcuma.…”

Pollen morphology of Chinese Curcuma L. and Boesenbergia Kuntz (Zingiberaceae): Taxonomic implications

“…Hitcheniopsis, this classification based on the position of the spikes. At the same time, present results show a surprisingly high morphological congruence between the pollen grains of Curcuma, which, based on molecular systematics, appears to be polyphyletic (Kress et al, 2002;Ngamriabsakul et al, 2004). However, the similarity of the pollen morphology must not provide unequivocal evidence for phylogenetic relationships.…”

Assessment of genetic diversity of Curcuma aromatica from eastern India using ISSR and RAPD markers

“…A phylogenetic analysis of the tribe Zingiberaceae was performed using nuclear ribosomal DNA and chloroplast DNA [20]. The study indicated that tribe Zingibereceae is monophyletic with two major clades, the Curcuma clade, and the Hedychium clade.…”
