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.
“…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.…”
Curcuma woodii, a new species of Curcuma subg. Ecomata (Zingiberaceae) from Thailand is described and illustrated here. It differs from C. rhomba by the leaf blades abaxially pubescent, the bracts whitish green, the labellum white with orange bands at the center, the lateral staminodes white with orange dots at the apex, and the ovary nearly glabrous.

“…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.…”

Molecular characterization of Curcuma aromatica from 4 different populations of Odisha using inter simple sequence repeats and random amplified polymorphic DNA markers to indicate the closeness of species and hybrids quickly and efficiently. A dendrogram was constructed through sequential agglomerative hierarchial and nested (SAHN) clustering and unweighted pair group method with arithmetic mean (UPGMA) analysis using Jaccard's similarity coefficient of combined markers using this particular species. Two major clusters were found i.e., cluster-I (Koraput-1, Koraput-2, Koraput-3, G.Udaigiri-1, G.Udaigiri-2, G.Udaigiri-3 and Phulabani-1, Phulabani-2, Phulabani-3) and cluster-II (Raikia-1, Raikia-2 and Raikia-3). The clustering pattern also revealed moreover the extent of genetic similarity between germplasms collected from four different regions population. The potential of this technique would be further realized to fullest extent for the identification and tagging of important novel gene in different taxa, unexplored yet, thus facilitating the improvement of desired taxa of Zingiberaceae. The findings would be of immense enough significance for complementing the strategies of conservation and characterization of these important taxa of Zingibearceae following modern biotechnological approach.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
