Abstract: Saussurea balangshanensis, based on populations from Balang Mountain in the Hengduan Mountains region, SW China, is described and illustrated as a new species of Asteraceae. It can be distinguished from other species in Saussurea by its concolorous leaves, swollen and hollow upper stems, articulate hairs and stipitate glandular hairs, laciniate margins of uppermost stem leaves, numerous and sessile capitula, and narrow involucre. Based on nucleotide sequence data from the internal transcribed spacer (ITS), phylogenetic analyses also support the recognition of these populations as representing a new species. The new species is known only from a single location in Balang Mountain, at elevations of 4500–4700 m. Its habitat can be easily disturbed or destroyed by a tourist arterial highway and the over grazing. We propose that the species should be listed as Critically Endangered based on the International Union for Conservation of Nature Red List Categories and Criteria B2a.

Diversity patterns of cushion plants on the Qinghai-Tibet Plateau: A basic study for future conservation efforts on alpine ecosystems
TL;DR: In this paper, the authors assessed spatial patterns of total cushion plant diversity (including taxonomic and phylogenetic) over the entire Qinghai-Tibet Plateau (QTP) and compared patterns of diversity of cushion plants with different typologies (i.e., compact vs. loose).

Xu Zhang,Jacob B. Landis,Jacob B. Landis,Yanxia Sun,Huajie Zhang,Tianjiao Feng,Nan Lin,Bashir Bolaji Tiamiyu,Xiu-Ying Huang,Tian Deng,Hengchang Wang,Hang Sun +11 more
TL;DR: In this paper, the authors investigate the role of abiotic and biotic factors in driving radiating diversification of Saussurea (Asteraceae) by deploying a number of time-dependent, paleoenvironment-dependent and trait-dependent models, as well as ecological distribution data.

Amplification and direct sequencing of fungal ribosomal RNA genes for phylogenetics
Thomas J. White
- 01 Jan 1990
Abstract: Comparative studies of the nucleotide sequences of ribosomal RNA (rRNA) genes provide a means for analyzing phylogenetic relation ships over a wide range of taxonomic levels (Woese and Olsen 1986; Zimmer et al 1988; Medlin et al 1988; Jorgensen and Cluster 1989). The nuclear small-subunit rDNA sequences (16S-like) evolve rela tively slowly and are useful for studying distantly related organisms, whereas the mitochondrial rRNA genes evolve more rapidly and can be useful at the ordinal or family level. The internal transcribed spacer region and intergenic spacer of the nuclear rRNA repeat units evolve fastest and may vary among species within a genus or among populations.
