“…The Brahmaputra, known as the Yarlong Tsangpo in its upper reaches, also is a biogeographic barrier in other plant groups, e.g. in Roscoea (Ngamriabsakul et al 2000), Morinaceae (Bell et al 2003), and Pleione (Gravendeel et al 2005), as well as for elephants (Vidya et al 2005).…”

Abstract. Biebersteiniaceae comprise a single genus with four species of perennial herbs occurring from central Asia to Greece. A previous molecular phylogenetic study placed one of the species in an isolated position in Sapindales, while morphological studies had placed Biebersteinia in or near Geraniaceae, albeit doubtfully. We tested the monophyly and placement of the family with data from the chloroplast genes rbcL and atpB obtained for all four species, other major clades of Sapindales and outgroups for a total of up to 114 taxa. Parsimony, Bayesian, and likelihood analyses place Biebersteinia in Sapindales, possibly as sister to the other eight families. Strict and relaxed molecular clocks constrained with fossils of Biebersteinia and up to eight other Sapindales suggest that the Biebersteinia crown group diversified in the Oligocene and Miocene, while the stem lineage dates back to the Late Paleocene. Ages for other sapindalean families are earlier than those obtained in more sparsely sampled analyses, although estimates for Burseraceae agree surprisingly well. Ancestral area analyses suggest that Biebersteinia expanded from the eastern part of its range (i.e. Tibet and Inner Mongolia) to the west, although analyses are hampered by the unclear sister group relationships.

“…Fresh leaf samples were taken and kept in dry silica gel before DNA extraction. The modified protocol for DNA extraction followed our previous study (Ngamriabsakul et al, 2000). The QIAgen Dneasy kit (QIAGEN, 1997) with liquid nitrogen was also used, with few modifications, to give high quality total DNA.…”

“…The PCR reaction mix was prepared before aliquoting to each tube and adding template DNA as the last component. The components and the conditions of the PCR followed Ngamriabsakul et al (2000), but with primer volume decreased to 2µl instead of 5µl. No significant reduction in products was detected.…”

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

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.

Phylogeny and biogeography of Morinaceae (Dipsacales) based on nuclear and chloroplast DNA sequences

The Morinaceae (Dipsacales) contains 13 species placed in Acanthocalyx, Cryptothladia or Morina, and is distributed from the mountains of southeastern Europe through the Himalayas to the Qinghai-Tibetan Plateau, mainly in alpine habitats. Sequence data from two chloroplast regions (the trnK intron and the trnL-F region) and the internal transcribed spacer (ITS) region of nuclear ribosomal DNA were used to infer phylogenetic relationships of Morinaceae and related Dipsacales. Both the nuclear and chloroplast datasets, as well as the combined data, provide strong support for relationships within the Valerina clade, placing Morinaceae as the sister group of a clade containing Valerianaceae and Dipsacaceae plus Triplostegia. The Morinaceae, Acanthocalyx, Cryptothladia, and a clade containing Morina and Cryptothladia, are all supported as monophyletic. However, Morina was found to be paraphyletic in several of our analyses, with Morina longifolia more closely related to Cryptothladia than to other Morina species. There is some evidence that Morina longifolia produces cleistogamous flowers, as do Cryptothladia species. Dispersal-vicariance analyses support the view that Valerina radiated initially within Asia, with subsequent movement into Europe in Morinaceae, Dipsacaceae, and Valerianaceae, and into the New World in Valerianaceae. For Morinaceae, as for a number of plant groups, the Brahmaputra river drainage marks a significant biogeographic divide, although this has been spanned within Acanthocalyx and the MorinaCryptothladia lineage.
