“…The nuclear ribosomal internal transcribed spacer (ITS) has been shown to be a useful source of information for resolving interspecific relationships in the Asteraceae (Baldwin 1992, Sang et al 1994, Sang et al 1995, Kim et al 1996, Kim et al 2005, Clevinger & Panero 2000, Francisco-Ortega et al 2001, Liu et al 2002, Zhang et al 2011. In addition, the plastid trnL-F, atpB-rbcL and rps16 regions have been used to reconstruct the phylogeny of some taxa of the family Asteraceae (Kim et al 2005, Wang et al 2007, Nakamura 2012.…”

A phylogenetic analysis and new delimitation of Crepidiastrum (Asteraceae, tribe Cichorieae)

The systematic position of Paraixeris humifusa (Asteraceae) is hard to define, because the circumscription of Paraixeris, Youngia and Crepidiastrum, three closely related genera in subtribe Crepidinae (Cichorieae), is not clear. This paper reports on the relationships between 30 species in subtribe Crepidinae, based on an analysis of nucleotides from one nuclear (ITS) and three chloroplast DNA regions ( trnL-F, rps16 and atpB-rbcL). The phylogenetic analyses used maximum parsimony with maximum likelihood inference. The monophyly of Crepidiastrum in the most recent generic classification of Shih & Kilian (2011) is explored. The results show that 12 species in Crepidiastrum constitute a monophyletic group, and that Paraixeris humifusa should be treated as Youngia humifusa.

A new genus of Compositae, Shangwua, is described to accomodate all species formerly placed in Saussurea sect. Jacea. This genus is distinct from the other genera of tribe Cardueae in its unique combination of states of characters including involucral bracts, receptacle, paleae, anther, style, achene and pappus. Phylogenetic analyses based on molecular data suggest that this new genus belongs to the Xeranthemum group, a lineage of the Carduinae that diversified early, with only distant relationships to Saussurea and related genera. The genus Shangwua consists of three species occurring in the Qinghai-Tibetan Plateau and Himalayas.

“…Two sections, corresponding to two previously described genera, Dolomiaea and Vladimiria, defined by Ling (1965), have been established within the genus based on the differences in style structure (long and acute versus short and round) (Shi 1987). In recent years, molecular phylogenetic analyses of this and related genera have suggested that Dolomiaea is a sister to the clade comprising Himalaiella, Jurinea and Lipschitziella (Wang et al 2007). In addition, phylogenetic analyses have suggested that two species, Frolovia frolovii and Saussurea costus, should be transferred to Dolomiaea (Wang et al 2007).…”

Chromosomal studies on the alpine genusDolomiaea(Asteraceae: Cardueae) from the Qinghai-Tibet Plateau and adjacent regions

Chromosomal characteristics are important for our understanding of the evolutionary history of species diversification. However, these characteristics are as yet unknown for some plant genera, especially those in alpine regions. In this study, our aim was to investigate the chromosome numbers and karyotypes of Dolomiaea, an alpine genus occurring in the Qinghai-Tibet Plateau and adjacent regions, for the first time. We report the chromosome numbers and karyotypes of 10 species originally assigned to Dolomiaea, one species which has been suggested should be transferred to this genus and one species from the closely related genus Himalaiella. Two chromosome numbers, i.e. 2n = 36 and 2n = 34, were found in these 12 species. One B chromosome was observed in two species. Karyotypes of all the species examined are relatively asymmetrical, and are classified as Stebbins' types 3B and 2B. These findings suggest that polyploidization events played a minor role in species diversification in this alpine genus. Aneuploidy and karyotypic differentiation at the diploid level, instead, contributed greatly to species diversification in this genus. However, many lines of evidence indicate that the ancestor of the genus originated from an ancient polyploidization event. In addition, our results provide cytological evidences of the transference of Frolovia frolovii and Saussurea costus to Dolomiaea, a recent proposal based on molecular phylogenetic context.
