The new genus and species Pulvinatusia xuegulaensis (Brassicaceae) are described and illustrated. The species is a cushion plant collected from Xuegu La, Xizang, China. Its vegetative parts are most similar to those of Arenaria bryophylla (Caryophyllaceae) co-occurring in the same region, while its leaves and fruits closely resemble those of Xerodr...

Euclidieae, a morphologically diverse tribe in the family Brassicaceae (Cruciferae), consists of 29 genera and more than 150 species distributed mainly in Asia. Prior phylogenetic analyses on Euclidieae are inadequate. In this study, sequence data from the plastid genome and nuclear ribosomal DNA of 72 species in 27 genera of Euclidieae were used t...

Crucihimalaya himalaica , a close relative of Arabidopsis and Capsella , grows on the Qinghai–Tibet Plateau (QTP) about 4,000 m above sea level and represents an attractive model system for studying speciation and ecological adaptation in extreme environments. We assembled a draft genome sequence of 234.72 Mb encoding 27,019 genes and investigated...

Sisymbriumlinifolium and Sisymbriopsisschugnana, previously confined to western North America and Tajikistan, respectively, were discovered in Xinjiang during a recent field trip to this autonomous region of China. The identity of these two species was subsequently confirmed by extensive morphological and molecular studies. The biogeographical sign...

Solms-laubachia tianbaoshanensis, a new species from the scree slopes and alpine meadows of Hengduan Mountains of NW Yunnan, China, is described and illustrated. It resembles S. linearifolia and S. pulcherrima in gross morphology but differs in having crisped simple subhirsute trichomes to 2 mm long, persistent sepals, pink petals, and longer fruit...

As currently delimitated, the species-rich mustard tribe Euclidieae DC. (Brassicaceae) comprises 28 genera and 152 species distributed primarily in Asia. To date, no tribe-wide comprehensive phylogenetic analysis has been conducted. In this study, sequence data from the nuclear ribosomal internal transcribed spacer (nrITS) region of 82 species in a...

Medog is well known as the last county with available public transportation in China. Although it has very lush vegetation, our knowledge on plants of Medog is very limited because the poor transportation condition impeded comprehensive botanical survey in this area. Here we gave a brief summary of the study history on flora of Medog, and then intr...

The taxonomic treatment within the unigeneric tribe Yinshanieae (Brassicaceae) is controversial, owing to differences in generic delimitation applied to its species. In this study, sequences from nuclear ITS and chloroplast trnL-F regions were used to test the monophyly of Yinshanieae, while two nuclear markers (ITS, ETS) and four chloroplast marke...

Chromist algae include diverse photosynthetic organisms of great ecological and social importance. Despite vigorous research efforts, a clear understanding of how various chromists acquired photosynthetic organelles has been complicated by conflicting phylogenetic results, along with an undetermined number and pattern of endosymbioses, and the hori...

The origin of plant auxin biosynthesis has long been controversial [1]. In our analyses of the TAA/YUC indole-3-acetic acid (IAA) biosynthetic pathway we suggested that this pathway evolved in land plants [2]. With the availability of Klebsormidium genome and other charophyte sequence data, Wang et al. performed additional phylogenetic analyses [3]...

Draba dongchuanensis is described, illustrated, and compared with several, primarily Himalayan and Tibetan species, including D. amplexicaulis, D. draboides, D. mongolica, D. polyphylla, D. setosa, and D. surculosa. From these, it is readily distinguished from all of the Himalayan species of Draba by a combination of strongly dilated filament bases...

The recent finding of the tryptophan aminotransferase (TAA)/flavin monooxygenase (YUC) pathway as the principal route of auxin production in plants provides an opportunity to revisit the origin of plant auxin biosynthesis. Phylogenetic analyses of the TAA and YUC gene families provide very little evidence for the production of indole-3-acetic acid...

Besides gene duplication and de novo gene generation, horizontal gene transfer (HGT) is another important way of acquiring new genes. HGT may endow the recipients with novel phenotypic traits that are important for species evolution and adaption to new ecological niches. Parasitic systems expectedly allow the occurrence of HGT at relatively high fr...

It is generally agreed that horizontal gene transfer (HGT) is common in phagotrophic protists. However, the overall scale of HGT and the cumulative impact of acquired genes on the evolution of these organisms remain largely unknown. Choanoflagellates are phagotrophs and the closest living relatives of animals. In this study, we performed phylogenom...

The 'Tanaka-Kaiyong Line' (TKL) is a major phytogeographic boundary in Southwest China, separating East Asia's Sino-Himalayan and Sino-Japanese Floras. However, little is known about the importance of this boundary in promoting intraspecific phylogeographic subdivision and divergence. Using chloroplast (cpDNA) and nuclear-intron (nDNA) sequence dat...

Horizontal gene transfer (HGT) has been well documented in prokaryotes and unicellular eukaryotes, but its role in plants and animals remains elusive. In a recent study, we showed that at least 57 families of nuclear genes in the moss Physcomitrella patens were acquired from prokaryotes, fungi or viruses and that HGT played a critical role in plant...

Horizontal gene transfer (HGT) may not only create genome mosaicism, but also introduce evolutionary novelties to recipient organisms. HGT in plastid genomes, though relatively rare, still exists. HGT‐derived genes are particularly common in unicellular photosynthetic eukaryotes and they also occur in multicellular plants. In particular, ancient HG...

In complex multicellular eukaryotes such as animals and plants, horizontal gene transfer is commonly considered rare with very limited evolutionary significance. Here we show that horizontal gene transfer is a dynamic process occurring frequently in the early evolution of land plants. Our genome analyses of the moss Physcomitrella patens identified...

In photosynthetic eukaryotes, many genes were transferred from plastids or algal endosymbionts to nuclear genomes of host cells. These transferred genes are often considered genetic footprints of plastids. However, genes of algal origin have also been detected in some plastid-lacking eukaryotes, and these genes are often cited as evidence of histor...

Background Horizontal gene transfer (HGT) is traditionally considered to be rare in multicellular eukaryotes such as animals. Recently, many genes of miscellaneous algal origins were discovered in choanoflagellates. Considering that choanoflagellates are the existing closest relatives of animals, we speculated that ancient HGT might have occurred i...

Abstract: The topological effect of the Hengduan Mountains (HM) during the Quaternary climatic oscillation must have important effects on spatial distribution and genetic structure of plants distributed there. In this study, we examined the chloroplast trnL-F and trnT-L sequence variation of Primula poissonii, a relatively common alpine perennial e...

Abstract: In this study, we examined the nuclear ribosomal DNA internal transcribed spacer (ITS) sequence variation of Eriophyton wallichii, a perennial endemic to alpine scree of the Qinghai-Tibetan Plateau. Nineteen haplotypes were detected by analyzing 187 individuals from 20 populations of E. wallichii. Most populations hold the unique haploty...

Abstract Salweenia (Leguminosae) has long been defined as a monotypic genus. In this study we carried out comprehensive studies on populations of S. wardii Baker f. across its distribution range. The results showed that this species diverged into two distinct groups: plants from the Yalong Jiang valley have linear leaflets 0.07–0.14 cm wide and rel...

Abstract The Hengduan Mountains region of south-west China is a noted biodiversity hotspot, but the geographic origins and historical assembly of its rich endemic flora, including the sky-island species of Solms-laubachia Muschl. (Brassicaceae), have been little studied. Previous molecular studies on the phylogeny of Solms-laubachia showed it to be...

Sequence data from the nuclear ribosomal ITS region and the chloroplast trnL-F were used to examine the generic delimitations of Solms-laubachia Muschl., Christolea Cambess., Desideria Pamp., Leiospora (C. A. Mey.) F. Dvořák, and Phaeonychium O. E. Schulz. Solms-laubachia, Desideria, and P. jafrii Al-Shehbaz formed a well-supported monophyletic cla...

Solms-laubachia eurycarpa is a medicinal herb endemic to the Hengduan Mountains region of south-central China. We screened a partial genomic library enriched for microsatellites and characterized 10 polymorphic loci for S. eurycarpa. The number of alleles per locus ranged from five to 15, with an average of 9.6. The observed and expected heterozygo...

Sequences of the plastid maturase (matK) and nuclear chalcone synthase (Chs) were analyzed separately and in combination to assess phylogenetic relationships of Solms-laubachia Muschl. (all nine known species and two undescribed ones) to the genera Baimashania Al-Shehbaz, Parrya R. Br., Desideria Pamp., Leiospora (C. A. Mey.) Dvořák, Christolea Cam...

Cytological studies were carried out on eight species of five genera (Anisodus , Atropanthe , Hyoscyamus , Mandragora and Przewalskia) in the tribe Hyoscyameae (Solanaceae). First chromosome counts were reported in six species: Ani-sodus luridus , A. acutangulus , A. tanguticus , A. carniolicoides , Atropanthe sinensis and Mandragora caulescens , a...

Solms-laubachia zhongdianensis J.P. Yue, Al-Shehbaz & H. Sun sp. nova (Brassi-caceae) is described from the Hengduan Mountains of Yunnan, China, and illustrated in...

Acer is one of the most diverse woody genera in the Northern Hemisphere. Recent phylogenetic studies support the placement of Acer and Dipteronia—sole members of the traditional Aceraceae—in the Sapindaceae. However, the monophyly of Acer and its sections remain to be tested. In this study, sequences of two chloroplast non-coding regions, psbM-trnD...

The karyotypes of six species of Solms-laubachia and one each of Parrya and Desideria (Brassicaceae) from the Himalayan-Hengduan Mountains (Tibet, Sichuan and Yunnan provinces) were investigated. Chromosome counts of S. xerophyta, S. lanata, S. platycarpa and D. baiogoinensis are reported for the first time and found to be diploid with 2n = 14. Dip...

The new genus and species Shangri-laia nana (Brassicaceae) are described and illus-trated, and their relationships to distinguishing characters from Braya and Baimashania are dis-cussed. Although a comprehensive account of the Bras-sicaceae for the Flora of China has recently been published (Zhou et al., 2001), many new taxa and new nomenclatural a...

The karyotypes of five species of Solms-laubachia (Brassicaceae) from Hengduan Mountains (Sichuan and Yunnan provinces) are investigated for the first time. The karyotype formulas of S. minor, S. eurycarpa, S. pulcherrima, and S. linearifolia are the same and all have 2n=14=6m+6sm+2st, whereas that of S. retropilosa is 2n=28=12m+12sm+4st. The first...
