The genome assembly and annotation of Magnolia biondii Pamp., a phylogenetically, economically, and medicinally important ornamental tree species

Shanshan Dong & Min Liu
Magnolia biondii Pamp. (Magnoliaceae, magnoliids) is a phylogenetically, economically, and medicinally important ornamental tree species widely grown and cultivated in the north-temperate regions of China. Contributing a genome sequence for M. biondii will help resolve phylogenetic uncertainty of magnoliids and further understand individual trait evolution in Magnolia. We assembled a chromosome-level reference genome of M. biondii using ~67, ~175, and ~154 Gb of raw DNA sequences generated by Pacific Biosciences Single-molecule Real-time sequencing, 10X genomics...

Thompson, Dahiana Arcila, Ricardo Betancur-R, Chenhong Li, Leandro Becker, Nicolás Bellora, Xiaomeng Zhao, Xiaofeng Li, Min Wang, Chao Fang, Bing Xie, Zhuocheng Zhou, Hai Huang, Songlin Chen, Byrappa Venkatesh & Qiong Shi
Our understanding of phylogenetic relationships among bony fishes has been transformed by analysis of a small number of genes, but uncertainty remains around critical nodes. Genome-scale inferences so far have sampled a limited number of taxa and genes. Here we leveraged 144 genomes and 159 transcriptomes to investigate fish evolution with an unparalleled scale of data: >0.5 Mb from 1,105 orthologous exon sequences from 303 species, representing 66 out of 72 ray-finned fish orders. We...

Data from: Re-assessing the diversity of negative strand RNA viruses in insects

Simon Käfer, Sofia Paraskevopoulou, Florian Zirkel, Nicolas Wieseke, Alexander Donath, Malte Petersen, Terry C. Jones, Shanlin Liu, Xin Zhou, Martin Middendorf, Sandra Junglen, Bernhard Misof & Christian Drosten
The spectrum of viruses in insects is important for subjects as diverse as public health, veterinary medicine, food production, and biodiversity conservation. The traditional interest in vector-borne diseases of humans and livestock has drawn the attention of virus studies to hematophagous insect species. However, these represent only a tiny fraction of the broad diversity of Hexapoda, the most speciose group of animals. Here, we systematically probed the diversity of negative strand RNA viruses in the...

Farr, Tomomichi Fujita, Yuji Hiwatashi, Yoshikazu Hoshi, Takamasa Imai, Masahiro Kasahara, Pablo Librado, Likai Mao, Hitoshi Mori, Tomoaki Nishiyama, Masafumi Nozawa, Gergő Pálfalvi, Stephen T. Pollard, Julio Rozas, Alejandro Sánchez-Gracia, David Sankoff, Tomoko F. Shibata, Shuji Shigenobu … & Mitsuyasu Hasebe
Carnivorous plants exploit animals as a nutritional source and have inspired long-standing questions about the origin and evolution of carnivory-related traits. To investigate the molecular bases of carnivory, we sequenced the genome of the heterophyllous pitcher plant Cephalotus follicularis, in which we succeeded in regulating the developmental switch between carnivorous and non-carnivorous leaves. Transcriptome comparison of the two leaf types and gene repertoire analysis identified genetic changes associated with prey attraction, capture, digestion and nutrient...

Data from: Genomic footprints of speciation in Atlantic eels (Anguilla anguilla and A. rostrata)

Magnus W. Jacobsen, Jose Martin Pujolar, Louis Bernatchez, Kasper Munch, Jianbo Jian, Yongchao Niu & Michael M. Hansen
The importance of speciation-with-gene-flow scenarios is increasingly appreciated. However, the specific processes and the resulting genomic footprints of selection are subject to much discussion. We studied the genomics of speciation between the two panmictic, sympatrically spawning sister-species; European (Anguilla anguilla) and American eel (A. rostrata). Divergence is assumed to have initiated more than 3 million years ago, and although low gene flow still occurs strong postzygotic barriers are present. Restriction-site Associated DNA (RAD) sequencing identified...

Data from: The genomic consequences of adaptive divergence and reproductive isolation between species of manakins

Thomas L. Parchman, Zachariah Gompert, Michael J. Braun, Robb T. Brumfield, D. B. McDonald, J. Albert C. Uy, G. Zhang, Erich D. Jarvis, B. A. Schlinger & C. A. Buerkle
The processes of adaptation and speciation are expected to shape genomic variation within and between diverging species. Here we analyze genomic heterogeneity of genetic differentiation and introgression in a hybrid zone between two bird species (Manacus candei and M. vitellinus) using 59 100 SNPs, a whole genome assembly, and Bayesian models. Measures of genetic differentiation (inline image) and introgression (genomic cline center [α] and rate [β]) were highly heterogeneous among loci. We identified thousands of...

Gut Microbiota from Multiple Sclerosis patients triggers spontaneous autoimmune encephalomyelitis in mice --shotgun data--

Hartmut Wekerle, Kerstin Berer, Lisa Ann Gerdes, Egle Cekanaviciute, Sherman Jia, Liang Xiao, Zhongkui Xia, Chuan Liu, Luisa Klotz, Uta Stauffer, Sergio Baranzini, Tania Kümpfel, Reinhard Hohlfeld & Gurumoorthy Krishnamoorthy
There is emerging evidence that the commensal microbiota has a role in the pathogenesis of multiple sclerosis (MS), a putative autoimmune disease of the central nervous system. Here, we compared the gut microbial composition of 34 monozygotic twin pairs discordant for MS. While there were no major differences in the overall microbial profiles, we found a significant increase in some taxa such as Akkermansia in untreated MS twins. Furthermore, most notably, when transplanted to a...

Data from: Stable recombination hotspots in birds

Sonal Singhal, Ellen M. Leffler, Keerthi Sannareddy, Isaac Turner, Oliver Venn, Daniel M. Hooper, Alva I. Strand, Qiye Li, Brian Raney, Christopher N. Balakrishnan, Simon C. Griffith, Gil McVean & Molly Przeworski
The DNA-binding protein PRDM9 has a critical role in specifying meiotic recombination hotspots in mice and apes, but it appears to be absent from other vertebrate species, including birds. To study the evolution and determinants of recombination in species lacking the gene that encodes PRDM9, we inferred fine-scale genetic maps from population resequencing data for two bird species: the zebra finch, Taeniopygia guttata, and the long-tailed finch, Poephila acuticauda. We found that both species have...

Data from: The plasticity of NBS resistance genes in sorghum is driven by multiple evolutionary processes

Emma S. Mace, Shuaishuai S. Tai, David J. Innes, Ian D. Godwin, Wushu S. Hu, Bradley C. Campbell, Edward K. Gilding, A. Cruickshank, Peter J. Prentis, Jun Wang & David R. Jordan
Background: Increased disease resistance is a key target of cereal breeding programs, with disease outbreaks continuing to threaten global food production, particularly in Africa. Of the disease resistance gene families, the nucleotide-binding site plus leucine-rich repeat (NBS-LRR) family is the most prevalent and ancient and is also one of the largest gene families known in plants. The sequence diversity in NBS-encoding genes was explored in sorghum, a critical food staple in Africa, with comparisons to...

Data from: Deciphering the origin of mito-nuclear discordance in two sibling caddisfly species

Hannah Weigand, Martina Weiss, Huimin Cai, Yongping Li, Lili Yu, Christine Zhang & Florian Leese
An increasing number of phylogenetic studies have reported discordances among nuclear and mitochondrial markers. These discrepancies are highly relevant to widely used biodiversity assessment approaches, such as DNA barcoding, that rely almost exclusively on mitochondrial markers. Although the theoretical causes of mito-nuclear discordances are well understood, it is often extremely challenging to determine the principal underlying factor in a given study system. In this study, we uncovered significant mito-nuclear discordances in a pair of sibling...

Neal Stewart, Gane K-S. Wong … & Claude De Pamphilis
Premise of the study: Understanding fern (monilophyte) phylogeny and its evolutionary timescale is critical for broad investigations of the evolution of land plants, and for providing the point of comparison necessary for studying the evolution of the fern sister group, seed plants. Molecular phylogenetic investigations have revolutionized our understanding of fern phylogeny, however, to date, these studies have relied almost exclusively on plastid data. Methods: Here we take a curated phylogenomics approach to infer the...

Data from: Genome of an iconic Australian bird: High-quality assembly and linkage map of the superb fairy-wren (Malurus cyaneus)

Joshua V. Peñalba, Yuan Deng, Qi Fang, Leo Joseph, Craig Moritz & Andrew Cockburn
The superb fairy-wren, Malurus cyaneus, is one of the most iconic Australian passerine species. This species belongs to an endemic Australasian clade, Meliphagides, which diversified early in the evolution of the oscine passerines. Today, the oscine passer- ines comprise almost half of all avian species diversity. Despite the rapid increase of available bird genome assemblies, this part of the avian tree has not yet been repre- sented by a high-quality reference. To rectify that, we...

Hardy, Irene Terry, Shanlin Liu, Xin Zhou, Bernhard Misof … & Kazunori Yoshizawa
Hemipteroid insects (Paraneoptera), with over 10% of all known insect diversity, are a major component of terrestrial and aquatic ecosystems. Previous phylogenetic analyses have not consistently resolved the relationships among major hemipteroid lineages. We provide maximum likelihood-based phylogenomic analyses of a taxonomically comprehensive dataset comprising sequences of 2,395 single-copy, protein-coding genes for 193 samples of hemipteroid insects and outgroups. These analyses yield a well-supported phylogeny for hemipteroid insects. Monophyly of each of the three hemipteroid...

Data from: Chromosomal level reference genome of Tachypleus tridentatus provides insights into evolution and adaptation of horseshoe crabs

Horseshoe crabs including Tachypleus tridentatus are a group of marine arthropods living fossil species which have existed on the earth for 500 million years. However, the genetic mechanisms underlying their unique adaptive ability are still unclear. Here, we assembled the first chromosome-level T. tridentatus genome, and proofed that this genome is of very high quality with contig N50 1.69 Mb. By comparison with other arthropods, some gene families of T. tridentatus experienced significant expansion, whichare...

A novel method for using RNA-seq data to identify imprinted genes in social Hymenoptera with multiply mated queens

Jack Howe, Morten Schiøtt, Qiye Li, Zongji Wang, Guojie Zhang & Jacobus Boomsma
Genomic imprinting results in parent-of-origin dependent gene expression biased towards either the maternally- or paternally-derived allele at the imprinted locus. The kinship theory of genomic imprinting argues that this unusual expression pattern is a manifestation of intra-genomic conflict between the maternally- and paternally-derived halves of the genome that arises because they are not equally related to the genomes of social partners. The theory thus predicts that imprinting may evolve wherever there are close interactions among...

Data from: Phylogenomics reveals the evolutionary timing and pattern of butterflies and moths

Akito Y. Kawahara, David Plotkin, Marianne Espeland, Karen Meusemann, Emmanuel F. A. Toussaint, Alexander Donath, France Gimnich, Paul B. Frandsen, Andreas Zwick, Mario Dos Reis, Jesse R. Barber, Ralph S. Peters, Shanlin Liu, Xin Zhou, Christoph Mayer, Lars Podsiadlowski, Caroline Storer, Jayne E. Yack, Bernhard Misof & Jesse W. Breinholt
Butterflies and moths (Lepidoptera) are one of the major super-radiations of insects, comprising nearly 160,000 described extant species. As herbivores, pollinators, and prey, Lepidoptera play a fundamental role in almost every terrestrial ecosystem. Lepidoptera are also indicators of environmental change and serve as model organisms for research on mimicry and genetics. They have been central to the development of co-evolutionary hypotheses, such as butterflies with flowering plants, and moths' evolutionary arms race with echolocating bats....

Genomic regions influencing aggressive behavior in honey bees are defined by colony allele frequencies

Arián Avalos, Miaoquan Fang, Hailin Pan, Aixa Ramirez Lluch, Alexander E. Lipka, Sihai Dave Zhao, Tugrul Giray, Gene E. Robinson, Guojie Zhang & Matthew E. Hudson
For social animals, the genotypes of group members affect the social environment, and thus individual behavior, often indirectly. We used genome-wide association studies (GWAS) to determine the influence of individual vs. group genotypes on aggression in honey bees. Aggression in honey bees arises from the coordinated actions of colony members, primarily nonreproductive “soldier” bees, and thus, experiences evolutionary selection at the colony level. Here, we show that individual behavior is influenced by colony environment, which...

The amount of RNA editing sites in liverwort organellar genes is correlated with GC content and nuclear PPR protein diversity

Shanshan Dong, Chaoxian Zhao, Shouzhou Zhang, Hong Wu, Weixue Mu, Tong Wei, Na Li, Tao Wan, Huan Liu, Jie Cui, Ruiliang Zhu, Bernard Goffinet & Yang Liu
RNA editing occurs in the organellar mRNAs of all land plants but the marchantioid liverworts, making liverworts a perfect group for studying the evolution of RNA editing. Here we profiled the RNA editing of 42 exemplars spanning the ordinal phylogenetic diversity of liverworts, and screened for the nuclear-encoded PPR proteins in the transcriptome assemblies of these taxa. We identified 7,428 RNA editing sites in 128 organellar genes from 31 non-marchantioid liverwort species, and characterized 25,059...

Data from: Dissecting molecular evolution in the highly diverse plant clade Caryophyllales using transcriptome sequencing

Ya Yang, Michael J. Moore, Samuel F. Brockington, Douglas E. Soltis, Gane Ka-Shu Wong, Eric J. Carpenter, Yong Zhang, Li Chen, Zhixiang Yan, Yinlong Xie, Rowan F. Sage, Sarah Covshoff, Julian M. Hibberd, Matthew N. Nelson & Stephen A. Smith
Many phylogenomic studies based on transcriptomes have been limited to “single-copy” genes due to methodological challenges in homology and orthology inferences. Only a relatively small number of studies have explored analyses beyond reconstructing species relationships. We sampled 69 transcriptomes in the hyperdiverse plant clade Caryophyllales and 27 outgroups from annotated genomes across eudicots. Using a combined similarity- and phylogenetic tree-based approach, we recovered 10,960 homolog groups, where each was represented by at least eight ingroup...

Data from: High-throughput monitoring of wild bee diversity and abundance via mitogenomics

Min Tang, Chloe J. Hardman, Yinqiu Ji, Guanliang Meng, Shanlin Liu, Meihua Tang, Shenzhou Yang, Ellen D. Moss, Jiaxin Wang, Chenxue Yang, Catharine Bruce, Tim Nevard, Simon G. Potts, Xin Zhou, Douglas W. Yu & Meihua Tan
1. Bee populations and other pollinators face multiple, synergistically acting threats, which have led to population declines, loss of local species richness and pollination services, and extinctions. However, our understanding of the degree, distribution and causes of declines is patchy, in part due to inadequate monitoring systems, with the challenge of taxonomic identification posing a major logistical barrier. Pollinator conservation would benefit from a high-throughput identification pipeline. 2. We show that the metagenomic mining and...

Gut Microbiota from Multiple Sclerosis patients triggers spontaneous autoimmune encephalomyelitis in mice --16S data--

Hartmut Wekerle, Kerstin Berer, Lisa Ann Gerdes, Egle Cekanaviciute, Sherman Jia, Liang Xiao, Zhongkui Xia, Chuan Liu, Luisa Klotz, Uta Stauffer, Sergio Baranzini, Tania Kümpfel, Reinhard Hohlfeld & Gurumoorthy Krishnamoorthy
The commensal microbiota has emerged as a key factor influencing human health and has been associated with several diseases, including those of the central nervous system (CNS). To investigate the role of the microbiome in multiple sclerosis (MS), a complex autoimmune disorder shaped by a multitude of genetic and environmental factors, we recruited a cohort of 34 monozygotic twin pairs discordant for MS, and compared their gut microbial composition by 16S ribosomal RNA sequencing of...

Data from: A chromosome-level genome assembly of the Asian arowana, Scleropages formosus

Jia Li, Chao Bian, Yinchang Hu, Xidong Mu, Xueyan Shen, Vydianathan Ravi, Inna S. Kuznetsova, Ying Sun, Xinxin You, Ying Qiu, Xinhui Zhang, Hui Yu, Yu Huang, Pao Xu, Ruobo Gu, Junmin Xu, László Orbán, Byrappa Venkatesh & Qiong Shi
Asian arowana (Scleropages formosus), an ancient teleost belonging to the Order Osteoglossomorpha, has been a valuable ornamental fish with some varieties. However, its biological studies and breeding germplasm have been remarkably limited by the lack of a reference genome. To solve these problems, here we report high-quality genome sequences of three common varieties of Asian arowana (the golden, red and green arowana). We firstly generated a chromosome-level genome assembly of the golden arowana, on basis...

Data from: Transcriptomic data from panarthropods shed new light on the evolution of insulator binding proteins in insects

Thomas Pauli, Lucia Vedder, Daniel Dowling, Malte Petersen, Karen Meusemann, Alexander Donath, Ralph S. Peters, Lars Podsiadlowski, Christoph Mayer, Shanlin Liu, Xin Zhou, Peter Heger, Thomas Wiehe, Lars Hering, Georg Mayer, Bernhard Misof & Oliver Niehuis
Background Body plan development in multi-cellular organisms is largely determined by homeotic genes. Expression of homeotic genes, in turn, is partially regulated by insulator binding proteins (IBPs). While only a few enhancer blocking IBPs have been identified in vertebrates, the common fruit fly Drosophila melanogaster harbors at least twelve different enhancer blocking IBPs. We screened recently compiled insect transcriptomes from the 1KITE project and genomic and transcriptomic data from public databases, aiming to trace the...

Data from: The genetic basis for ecological adaptation of the Atlantic herring revealed by genome sequencing

Alvaro Martinez Barrio, Sangeet Lamichhaney, Guangyi Fan, Nima Rafati, Mats Pettersson, He Zhang, Jacques Dainat, Diana Ekman, Marc Höppner, Patric Jern, Marcel Martin, Björn Nystedt, Xin Liu, Wenbin Chen, Xinming Liang, Chengcheng Shi, Yuanyuan Fu, Kailong Ma, Xiao Zhan, Chungang Feng, Ulla Gustafson, Carl-Johan Rubin, Markus Sällman Almén, Martina Blass, Michele Casini … & Leif Andersson
Ecological adaptation is of major relevance to speciation and sustainable population management, but the underlying genetic factors are typically hard to study in natural populations due to genetic differentiation caused by natural selection being confounded with genetic drift in subdivided populations. Here, we use whole genome population sequencing of Atlantic and Baltic herring to reveal the underlying genetic architecture at an unprecedented detailed resolution for both adaptation to a new niche environment and timing of...
