Abstract We reconstructed a phylogenetic tree of Chinese vascular plants (Tracheophyta) using sequences the chloroplast genes atpB , matK ndhF and rbcL mitochondrial matR . produced matrix comprising 6098 species including 13 695 DNA sequences, which 1803 were newly generated. Our taxonomic sampling spanned 3114 genera representing 323 families plants, covering more than 93% all known from China. The comprehensive large phylogeny supports most relationships among within recognized by recent molecular studies for lycophytes, ferns (monilophytes), gymnosperms, angiosperms. For angiosperms, in Angiosperm Phylogeny Group IV are supported as monophyletic, except paraphyletic Dipterocarpaceae Santalaceae. infrafamilial several monophyly some well our dense sampling. results showed that two Eberhardtia sister to clade formed other taxa Sapotaceae, Sarcosperma have made publically available creation subtrees via SoTree ( http://www.darwintree.cn/flora/index.shtml ), an automated assembly tool ecologists.

Impacts of Quaternary glaciation, geological history and geography on animal species history in continental East Asia: A phylogeographic review

Molecular Ecology, Год журнала: 2023, Номер 32(16), С. 4497 - 4514

Опубликована: Июнь 18, 2023

Abstract Continental East Asia has a mild Pleistocene climate and complex recent geological history. Phylogeographic studies of animals over the last 30 years have produced several distinctive patterns. Glaciation refugia are numerous not restricted to any particular regions. Most them localized species‐specific, although large refugia, for example mountains SW China, shared by multiple species refugia‐within‐refugia. Furthermore, postglaciation range expansion events vary greatly in time, scale direction. Large‐scale south‐to‐north post‐LGM expansions few mostly occurred northern Additionally, unique geographic features, including three‐step terrain China arid belt, significant impacts on many histories. Overall, glaciations, particularly LGM, history drastically from nondetectable significant. The least southwestern region most dominant north. Geological play more role shaping than climatic changes. patterns among highly consistent with those plants. Future phylogeographic endeavour should be hypothesis‐driven seek processes that underlie common wide use genomic data allow accurate estimates historical population exploration older beyond Pleistocene.

A multilocus assessment reveals two new synonymies for East Asian Cyclommatus stag beetles (Coleoptera, Lucanidae)

ZooKeys, Год журнала: 2021, Номер 1021, С. 65 - 79

Опубликована: Март 2, 2021

Cyclommatus scutellaris Möllenkamp, 1912, elsae Kriesche, 1921 and tamdaoensis Fujita, 2010 are East Asian stag beetle species with long-debated taxonomic relationships due to high intraspecific morphological variability. In this study, we applied multilocus phylogenetic analyses reassess their relationships. Two mitochondrial genes (16S rDNA, COI) two nuclear (28S Wingless) were used reconstruct the phylogeny through Bayesian inference (BI) Maximum Likelihood (ML) methods. Both topologies supported clades: clade C. was sister ( + ) subclade embedded in . The Kimura 2-parameter (K2P) genetic distance analysis yielded a low mean value (≤0.035) among three taxa, which well below minimum between other (≥0.122). We also compared accuracy efficiency of approaches, GMYC ABGD, delimitating lineages. result shows that ABGD is better approach than GMYC. Our molecular data recognizes as different populations single species, ranging from Taiwan Island continent. Therefore, propose new junior synonyms for : , syn. nov.

Phylogeographic patterns of the desert poplar in Northwest China shaped by both geology and climatic oscillations

BMC Evolutionary Biology, Год журнала: 2018, Номер 18(1)

The effects of historical geology and climatic events on the evolution plants around Qinghai-Tibetan Plateau region have been at center debate for years. To identify influence uplift Tianshan Mountains and/or oscillations in arid northwest China, we investigated phylogeography Euphrates poplar (Populus euphratica) using chloroplast DNA (cpDNA) sequences nuclear microsatellites, estimated its distribution Ecological Niche Modeling (ENM). We found that differed from another desert poplar, P. pruinosa, both DNA. low clonal diversity populations reflected regeneration rate by seed/seedlings many locations. Both cpDNA markers demonstrated a clear divergence between northern southern Xinjiang regions. time was to be early Pleistocene based cpDNA, late an Approximate Bayesian Computation analysis microsatellites.

Phylogeny and biogeography of Artemisia subgenus Seriphidium (Asteraceae: Anthemideae)

Taxon, Год журнала: 2017, Номер 66(4), С. 934 - 952

Опубликована: Авг. 1, 2017

Abstract Artemisia subg. Seriphidium is one of the largest groups within , encompassing more than hundred species, some them having considerable ecological and economical importance. However, evolution has received less attention in comparison to other subgenera probably, apart from difficulty sampling throughout its very large distribution area, because low molecular morphological variability observed previous studies. Here, we use thorough taxonomic both reconstruct evolutionary history subgenus, employing nuclear plastid DNA sequences as well various phylogenetic, biogeographic diversification dynamics tools analyse data. Our results show that not monophyletic, but segregated into two main clades: monophyletic group corresponding formerly recognised sect. a second, small clade, phylogenetically distant first. Biogeographic analyses indicate rapid radiation species occurred Central Asia during Miocene‐Pliocene transition. The our analysis suggest this process started around Tian‐Shan, Pamir Hindu Kush mountain ranges, subsequently expanding Eurasian continent. Finally, uncovered numerous incongruences between genetic information several which could be explained by uniformity, hybridisation and/or incomplete lineage sorting processes.

Planted forest is catching up with natural forest in China in terms of carbon density and carbon storage

Fundamental Research, Год журнала: 2022, Номер 2(5), С. 688 - 696

Опубликована: Апрель 22, 2022

Over the last several decades, China has taken multiple measures for afforestation and natural forest protection, including setting goal of carbon neutrality by middle 21th century. In order to support practice relevant policies from scientific perspective, it is essential precisely estimate storage arbor forest, as plays an important role in cycle ecosystems. this study, we first used latest four phases national inventory data investigate variation both planted during covered period (1999-2018). Then machine leaning methods simulate density based on various kinds environmental factors analyzed contribution each influencing factor. Our results demonstrate that total kept increasing over two but increment was mainly brought about continuous expansion land. The gap sequestration between showed a significant trend reduction. Additionally, tree age identified dominant factor spatiotemporal among all independent variables while impact climatic limited. Therefore, future improvement should rely additional projects afforestation, reforestation, green space conservation reduction emissions China. Conclusions study have implications policy makers other stakeholders evaluate previous achievement can also help set plans finally realize goals neutrality.

Improved Tolerance of Artemisia ordosica to Drought Stress via Dark Septate Endophyte (DSE) Symbiosis

Journal of Fungi, Год журнала: 2022, Номер 8(7), С. 730 - 730

Опубликована: Июль 13, 2022

Dark septate endophytes (DSEs) usually colonize plant roots, especially in stress environments. However, their relationship with plants ranges from beneficial to harmful and has remained largely uncharacterized. In the present study, 14 DSE species grouped into 11 genera were isolated roots of a desert plant, Artemisia ordosica, which is widely distributed northwest China. Three dominant species-Paraphoma chrysanthemicola (Pc), Alternaria chartarum (Ac), Acrocalymma vagum (Av)-were selected tested for resistance drought vitro. Furthermore, we characterized responses A. ordosica under conditions relation presence these DSEs following inoculation. The results showed that all three strains grew well vitro stress, biomass Ac Av was significantly higher than unstressed control. effects inoculation on growth varied according different but generally beneficial. Under Pc promoted growth, antioxidant enzyme activity, root development hosts. strain conferred obvious positive activity general, demonstrated better application potential improving ordosica.
