Population genetic assessment of newly discovered, extremely small populations of Xanthocyparis Vietnamensis from southwestern China

Yu-Liang Jiang, Tsam Ju, Linda Neaves, Jia-Liang Li, Wei-Ning Tan, Yu-Song Huang, Yan Liu & Kang-Shan Mao
Xanthocyparis vietnamensis is an endangered species that is currently restricted to karst montane areas in southwestern China and Vietnam. This rare conifer was first recorded in 2002 from northern Vietnam and then in 2013 from Guangxi, China, yet little is known about its genetic diversity and population structure. We developed expressed sequence tag microsatellite markers (EST-SSR) for X. vietnamensis. Illumina HiSeq data were used to reconstruct the transcriptome of this species by de novo assembly....

Data from: Phylogenetic niche conservatism and variations in species diversity-climate relationships

Qinggang Wang, Yaoqi Li, Dongting Zou, Xiangyan Su, Hongyu Cai, Ao Luo, Ke Jiang, Xiaoling Zhang, Xiaoting Xu, Nawal Shrestha & Zhiheng Wang
Although contemporary climate has been identified as one of the major determinants of large-scale species diversity patterns, its effect on species diversity greatly varies among clades. Understanding the drivers of the variation in species diversity-climate relationships (DCRs) across clades, which is critical for developing general mechanisms underlying the effects of climate on species diversity patterns, remains a current challenge. Using newly compiled distribution data of 914 Rosaceae species in China and a dated genus-level phylogeny,...

Flying over phylogeographic breaks by wind: Quaternary evolutionary history of a mountain aspen in southwestern China

Jieshi Tang
The role of phylogeographic break and wind direction in the formation of plant genetic pattern has aroused increasing interest. Two phylogeographic breaks, MSD and TKL, existed in the Sino-Japanese floristic region have affected many plants, but there was no landscape genetic research across these two phylogeographic breaks. Here, we tested the internal and external factors that influence the phylogeographic pattern of Populus rotundifolia. Genetic variation was surveyed across 49 populations (567 individuals) covering the Chinese...

Global distribution and evolutionary transitions of angiosperm sexual systems

Yunyun Wang, Ao Luo, Tong Lyu, Dimitar Dimitrov, Xiaoting Xu, Robert Freckleton, Yaoqi Li, Xiangyan Su, Yichao Li, Yunpeng Liu, Denis Sandanov, Qingjun Li, Zhanqing Hao, Shuguang Liu & Zhiheng Wang
Angiosperm sexual systems are fundamental to the evolution and distribution of plant diversity, yet spatiotemporal patterns in angiosperm sexual systems and their drivers remain poorly known. Using data on sexual systems and distributions of 68453 angiosperm species, we present the first global maps of sexual system frequencies and evaluate sexual system evolution during the Cenozoic. Frequencies of dioecy and monoecy increase with latitude, while hermaphrodites are more frequent in warm and arid regions. Transitions to...

Telerehabilitation program for COVID-19 survivors (TERECO) - Randomized controlled trial

Jan D. Reinhardt
Objectives To investigate superiority of a telerehabilitation program for Covid-19 (TERECO) over no rehabilitation with regard to exercise capacity, lower-limb muscle strength (LMS), pulmonary function, health-related quality of life (HRQOL), and dyspnoea. Design Parallel-group randomised controlled-trial with 1:1 block-randomisation. Setting Three major hospitals from Jiangsu and Hubei provinces, China. Participants 120 formerly hospitalised Covid-19 survivors with remaining dyspnoea complaints were randomised with 61 allocated to control and 59 to TERECO. Intervention Unsupervised home-based 6-week exercise...

Seeing through the hedge: Phylogenomics of Thuja (Cupressaceae) reveals prominent incomplete lineage sorting and ancient introgression for Tertiary relict flora

Jialiang Li, Yujiao Zhang, Markus Ruhsam, Richard Ian Milne, Yi Wang, Dayu Wu, Shiyu Jia, Tongzhou Tao & Kangshan Mao
The eastern Asia (EA) – eastern North America (ENA) disjunction is a typical and well known biogeographic. Although its origin has been the topic of many studies, some new insights will arise when more complex evolutionary histories are revealed using phylogenomic methods. Here, we used targeted exon capture and sequenced >1,000 single copy nuclear, plus 73 chloroplast genes, to resolve interspecific relationships and the biogeographic history of an intercontinental disjunct genus Thuja. Two separate clades...

The draft genome of the blood pheasant (Ithaginis cruentus): phylogeny and high-altitude adaptation

Zhou Chuang
The blood pheasant (Ithaginis cruentus), the only species in the genus Ithaginis lives in an extremely inhospitable high-altitude environment, coping with hypoxia and UV radiation. To further investigate the phylogeny of Phasianidae species based on complete genomes and understand the molecular genetic mechanisms of the high-altitude adaptation of the blood pheasant, we de novo assembled and annotated the complete genome of the blood pheasant. The blood pheasant genome size is 1.04 Gb with scaf N50...

Datasets for phylogenetic analysis on Angelica

Chenyang Liao
There are four datasets used for constructing the phylogenetic trees in "A systematic study of North American Angelica species (Apiaceae) based on nrDNA ITS and cpDNA sequences and fruit morphology" Dataset I included the entire ITS region from 231 representatives of Apiaceae subfamily Apioideae. Datasets II-IV each included the same 176 accessions and comprised all 26 NA species of Angelica (represented by 132 accessions) and other related species. Dataset II included the entire ITS region;...

Influence of early thermal-oxidative ageing on the structure and properties of polyoxymethylene copolymer

Yuan-Jin Pang, Wen-Shuai Xu, Ben-Tengzi Yang, Hai-Ying Ni & Jun Chen
Thermal-oxidative ageing of polyoxymethylene (POM) copolymer in oven at 100 °C for 1, 2, 3, 5, 7, 10, 14 and 21 days and the influence of early thermal-oxidative on POM structure and properties were studied by means of wide-angle X-ray diffraction (WAXD), Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC) and tensile test. Based on the results, we found that the early thermal-oxidative ageing of POM copolymer can be divided into three regions. The...

Comparison among the chloroplast genomes of five species of Chamaerhodos (Rosaceae: Potentilleae): phylogenetic implications

Qin-Qin Li, Yan Yu, Zhi-Ping Zhang & Jun Wen
Chamaerhodos is a small genus with ca 7–8 species with a disjunct distribution in Asia and western North America. Due to limited sampling of species and genes in previous studies, little is known about the phylogenetic relationships among the species. Moreover, chloroplast genomic resources for Chamaerhodos have been limited. Herein, we conducted a comparative analysis of the complete chloroplast (cp) genomes of five Chamaerhodos species. The five cp genomes had a typical quadripartite structure with...
