Two leaves that cannot die: the genome sequence of Welwitschia mirabilis reveals its unique biology and evolutionary history

Zhiming Liu, Tao Wan & Qingfeng Wang
Welwitschia mirabilis (hereafter Welwitschia), the sole species in Welwitschiales, belongs to gnetophytes, an ancient, enigmatic gymnosperm lineage. It is a strikingly bizarre plant with distinctive morphology of just two large ever-elongating leaves and is remarkable in being able to survive extreme environmental stresses of the Namibian and Angolan deserts. Here, we provide a chromosome-level assembly of its genome (6.8 Gb/1C) and extensive methylome and transcriptome data to reveal the genetics underpinning its intriguing biology. The...

From Black Box to Shining Spotlight: Using Random Forest Prediction Intervals to Illuminate the Impact of Assumptions in Linear Regression

Andrew J. Sage, Yang Liu & Joe Sato
We introduce a pair of Shiny web applications that allow users to visualize random forest prediction intervals alongside those produced by linear regression models. The apps are designed to help undergraduate students deepen their understanding of the role that assumptions play in statistical modeling by comparing and contrasting intervals produced by regression models with those produced by more flexible algorithmic techniques. We describe the mechanics of each approach, illustrate the features of the apps, provide...

The hornwort genome and early land plant evolution

Jian Zhang, Xin-Xing Fu, Rui-Qi Li, Xiang Zhao, Yang Liu, Ming-He Li, Arthur Zwaenepoel, Hong Ma, Bernard Goffinet, Yan-Long Guan, Jia-Yu Xue, Yi-Ying Liao, Qing-Feng Wang, Qing-Hua Wang, Jie-Yu Wang, Guo-Qiang Zhang, Zhi-Wen Wang, Yu Jia, Mei-Zhi Wang, Shan-Shan Dong, Jian-Fen Yang, Yuan-Nian Jiao, Ya-Long Guo, Hong-Zhi Kong, An-Ming Lu … & Zhi-Duan Chen
Hornworts, liverworts, and mosses are three early diverging clades of land plants, together composing the bryophytes. Here we report the draft genome sequence of the hornwort Anthoceros angustus. Phylogenomic inferences confirm the monophyly of bryophytes, with hornworts sister to liverworts and mosses. The simple morphology of hornworts correlates with low genetic redundancy in plant body plan while the basic transcriptional regulation toolkit for plant development has already been established in this early land plant lineage....

Data from: Resolution of the ordinal phylogeny of mosses using targeted exons from organellar and nuclear genomes

Yang Liu, Matthew G. Johnson, Cymon J. Cox, Rafael Medina, Nicolas Devos, Alain Vanderpoorten, Lars Hedenäs, Neil E. Bell, James R. Shevock, Blanka Aguero, Dietmar Quandt, Norman J. Wickett, A. Jonathan Shaw & Bernard Goffinet
Mosses are a highly diverse lineage of land plants, whose diversification, spanning at least 400 million years, remains phylogenetically ambiguous due to the lack of fossils, massive early extinctions, late radiations, limited morphological variation, and conflicting signal among previously used markers. Here, we present phylogenetic reconstructions based on complete organellar exomes and a comparable set of nuclear genes for this major lineage of land plants. Our analysis of 142 species representing 29 of the 30...

Data from: A genome for gnetophytes and early evolution of seed plants

Gnetophytes are an enigmatic gymnosperm lineage comprising three genera, Gnetum, Welwitschia and Ephedra, which are morphologically distinct from all other seed plants. Their distinctiveness has triggered much debate as to their origin, evolution and phylogenetic placement among seed plants. To increase our understanding of the evolution of gnetophytes, and their relation to other seed plants, we report here a high-quality draft genome sequence for Gnetum montanum, the first for any gnetophyte. By using a novel...

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...

Mingyu Wen, Junxian Xu, Jiazhi Zhu, Yang Liu, Chao Deng, Junyou Shi & Heejun Park
A new type of polyhedral oligomeric silsesquioxanes bisDOPO-NH2-POSS flame retardant consisting of one polyhedral oligomeric silsesquioxane (POSS), two units of 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) and reactive –NH2 groups, was synthesized and characterized by FTIR, 1H NMR, and 31P NMR. It was applied to modified conventional environmentally friendly E0 grade urea formaldehyde (UF) resin to prepare flame-retardant plywood. Two other POSS structure flame retardants were used for comparison. The results showed that the addition of bisDOPO-NH2-POSS flame retardant...
