| 1 | Genome-wide transcriptome analysis reveals molecular pathways involved in leafy head formation of Chinese cabbage(Brassica rapa)显示文摘Chinese cabbage plants go through seedling and rosette stages before forming their leafy head.Chinese cabbage plants resemble pak-choi plants at their seedling stage,but in their rosette stage the leaves of Chinese cabbage differentiate,as they increase in size with shorter petioles.In order to understand the molecular pathways that play a role in leafy head formation,transcript abundance of young emerging leaves was profiled during development of two Chinese cabbage genotypes and a single pak-choi genotype.The two Chinese cabbages differed in many aspects,among others earliness,leaf size and shape,leaf numbers,and leafy head shape.Genome-wide transcriptome analysis clearly separated the seedling stages of all three genotypes together with the later stages from pak-choi,from the later developmental stages of both Chinese cabbages(rosette,folding,and heading).Weighted correlation network analysis and hierarchical clustering using Euclidean distances resulted in gene clusters with transcript abundance patterns distinguishing the two Chinese cabbages from pak-choi.Three clusters included genes with transcript abundance affected by both genotype and developmental stage,whereas two clusters showed only genotype effects.This included a genotype by developmental stage cluster highly enriched with the MapMan category photosynthesis,with high expression during rosette and folding in Chinese cabbages and low expression in the heading inner leaves that are not exposed to light.The other clusters contained many genes in the MapMan categories Cell,showing again differences between pak-choi and both Chinese cabbages.We discuss how this relates to the differences in leaf blade growth between Chinese cabbage and pak-choi,especially at the rosette stage.Overall,comparison of the transcriptome between leaves of two very different Chinese cabbages with pak-choi during plant development allowed the identification of specific gene categories associated with leafy head formation. | XiaoXue Sun Ram Kumar Basnet Zhichun Yan Johan Bucher Chengcheng Cai Jianjun Zhao Guusje Bonnema | 2019 | Horticulture Research2019，6，1： | 4 |

| 4 | Challenges in the Detection and Attribution of Northern Hemisphere Surface Temperature Trends Since 1850显示文摘Since 2007,the Intergovernmental Panel on Climate Change(IPCC)has heavily relied on the comparison between global climate model hindcasts and global surface temperature(ST)estimates for concluding that post-1950s global warming is mostly human-caused.In Connolly et al.,we cautioned that this approach to the detection and attribution of climate change was highly dependent on the choice of Total Solar Irradiance(TSI)and ST data sets.We compiled 16 TSI and five ST data sets and found by altering the choice of TSI or ST,one could(prematurely)conclude anything from the warming being“mostly human-caused”to“mostly natural.”Richardson and Benestad suggested our analysis was“erroneous”and“flawed”because we did not use a multilinear regression.They argued that applying a multilinear regression to one of the five ST series re-affirmed the IPCC's attribution statement.They also objected that many of the published TSI data sets were out-of-date.However,here we show that when applying multilinear regression analysis to an expanded and updated data set of 27 TSI series,the original conclusions of Connolly et al.are confirmed for all five ST data sets.Therefore,it is still unclear whether the observed warming is mostly human-caused,mostly natural or some combination of both. | Ronan Connolly Willie Soon Michael Connolly Sallie Baliunas Johan Berglund C.J.Butler Rodolfo Gustavo Cionco Ana G.Elias Valery M.Fedorov Hermann Harde Gregory W.Henry Douglas V.Hoyt Ole Humlum David R.Legates Nicola Scafetta Jan-Erik Solheim LászlóSzarka Víctor M.Velasco Herrera Hong Yan Weijia Zhang | 2023 | Research in Astronomy and Astrophysics2023，23，10： | 1 |
| 5 | Improving ITS sequence data for identification of plant pathogenic fungi显示文摘Plant pathogenic fungi are a large and diverse assemblage of eukaryotes with substantial impacts on natural ecosystems and human endeavours.These taxa often have complex and poorly understood life cycles,lack observable,discriminatory morphological characters,and may not be amenable to in vitro culturing.As a result,species identification is frequently difficult.Molecular(DNA sequence)data have emerged as crucial information for the taxonomic identification of plant pathogenic fungi,with the nuclear ribosomal internal transcribed spacer(ITS)region being the most popular marker.However,international nucleotide sequence databases are accumulating numerous sequences of compromised or low-resolution taxonomic annotations and substandard technical quality,making their use in the molecular identification of plant pathogenic fungi problematic.Here we report on a concerted effort to identify high-quality reference sequences for various plant pathogenic fungi and to re-annotate incorrectly or insufficiently annotated public ITS sequences from these fungal lineages.A third objective was to enrich the sequences with geographical and ecological metadata.The results-a total of 31,954 changes-are incorporated in and made available through the UNITE database for molecular identification of fungi(http://gffzz7cc2bea597fa4d6chx9b0n0wpnu6b6bcw.ffgz.tsg.suse.edu.cn),including standalone FASTA files of sequence data for local BLAST searches,use in the next-generation sequencing analysis platforms QIIME and mothur,and related applications.The present initiative is just a beginning to cover the wide spectrum of plant pathogenic fungi,and we invite all researchers with pertinent expertise to join the annotation effort. | R.Henrik Nilsson Kevin D.Hyde Julia Pawlowska Martin Ryberg Leho Tedersoo Anders Bjornsgard Aas Siti A.Alias Artur Alves Cajsa Lisa Anderson Alexandre Antonelli A.Elizabeth Arnold Barbara Bahnmann Mohammad Bahram Johan Bengtsson-Palme Anna Berlin Sara Branco Putarak Chomnunti Asha Dissanayake Rein Drenkhan Hanna Friberg Tobias Guldberg Froslev Bettina Halwachs Martin Hartmann Beatrice Henricot Ruvishika Jayawardena Ari Jumpponen Havard Kauserud Sonja Koskela Tomasz Kulik Kare Liimatainen Bjorn D.Lindahl Daniel Lindner Jian-Kui Liu Sajeewa Maharachchikumbura Dimuthu Manamgoda Svante Martinsson Maria Alice Neves Tuula Niskanen Stephan Nylinder Olinto Liparini Pereira Danilo Batista Pinho Teresita M.Porter Valentin Queloz Taavi Riit Marisol Sánchez-García Filipe de Sousa Emil Stefańczyk Mariusz Tadych Susumu Takamatsu Qing Tian Dhanushka Udayanga Martin Unterseher Zheng Wang Saowanee Wikee Jiye Yan Ellen Larsson Karl-Henrik Larsson Urmas Koljalg Kessy Abarenkov | 2014 | Fungal Diversity2014，，4： | 1 |

| 10 | Observation of magnetic droplets in magnetic tunnel junctions显示文摘Magnetic droplets,a class of highly nonlinear magnetodynamic solitons,can be nucleated and stabilized in nanocontact spintorque nano-oscillators.Here we experimentally demonstrate magnetic droplets in magnetic tunnel junctions(MTJs).The droplet nucleation is accompanied by power enhancement compared with its ferromagnetic resonance modes.The nucleation and stabilization of droplets are ascribed to the double-Co Fe B free-layer structure in the all-perpendicular MTJ,which provides a low Zhang-Li torque and a high pinning field.Our results enable better electrical sensitivity in fundamental studies of droplets and show that the droplets can be utilized in MTJ-based applications and materials science. | Kewen Shi Wenlong Cai Sheng Jiang Daoqian Zhu Kaihua Cao Zongxia Guo Jiaqi Wei Ao Du Zhi Li Yan Huang Jialiang Yin Johan Akerman Weisheng Zhao | 2022 | Science China(Physics,Mechanics & Astronomy)2022，65，2： | 0 |
| 11 | Shear banding-inducedslip enables unprecedented strength-ductility combination of laminated metallic composites显示文摘Shear bands in metallic materials have been reported to be catastrophic because they normally lead to non-uniform plastic deformation. Ductility of laminated metallic composites deteriorates with increasing processing strain, particularly for those having hexagonal-close-packed(hcp) constituents due to inadequate slip systems and consequently prominent shear banding. Here, we propose a design strategy that counterintuitively tolerates the bands with localized strains, i.e. the shear banded laminar(SBL) structure, which promotes dislocation activation in hcp metals and renders unprecedented strengthductility combination in hcp-metal-based composites fabricated by accumulative roll bonding(ARB). The SBL structure is characterized with one soft hcp metal constrained by adjacent hard metal in which dislocations have been accumulated near the bimetal interfaces. High-energy X-ray diffraction astonishingly reveals that more than 90% of dislocations are non-basal in Ti layers of the SBL Ti/Nb composite processed by eight ARB cycles. Moreover, dislocations occupy a high fraction of ~30%, promoting further cross slip. The unique stress field tailored by both shear banding and heterophase interface-mediated deformation accommodation triggers important slip. This SBL design is of significance for developing hcp-based laminates and other heterostructured materials with high performances. | Shuang Jiang Ru Lin Peng Kristián Máthis Hai-Le Yan Gergely Farkas Zoltán Hegedues Ulrich Lienert Johan Moverare Xiang Zhao Liang Zuo Nan Jia Yan-Dong Wang | 2022 | Journal of Materials Science & Technology2022，，15： | 0 |
| 12 | Reassessment of historical sections from the Paleogene marine margin of the Congo Basin reveals an almost complete absence of Danian deposits显示文摘The early Paleogene is critical for understanding global biodiversity patterns in modern ecosystems. During this interval, Southern Hemisphere continents were largely characterized by isolation and faunal endemism following the breakup of Gondwana. Africa has been proposed as an important source area for the origin of several marine vertebrate groups but its Paleogene record is poorly sampled, especially from sub-Saharan Africa. To document the early Paleogene marine ecosystems of Central Africa, we revised the stratigraphic context of sedimentary deposits from three fossil-rich vertebrate localities: the Landana section in the Cabinda exclave(Angola), and the Manzadi and Bololo localities in western Democratic Republic of Congo.We provide more refined age constraints for these three localities based on invertebrate and vertebrate faunas, foraminiferal and dinoflagellate cyst assemblages, and carbon isotope records. We find an almost complete absence of Danian-aged rocks in the Landana section, contrary to prevailing interpretations over the last half a century(only the layer 1, at the base of the section, seems to be Danian). Refining the age of these Paleocene layers is crucial for analyzing fish evolution in a global framework, with implications for the early appearance of Scombridae(tunas and mackerels) and Tetraodontiformes(puffer fishes). The combination of vertebrate fossil records from Manzadi and Landana sections suggests important environmental changes around the K/Pg transition characterized by an important modification of the ichthyofauna. A small faunal shift may have occurred during the Selandian. More dramatic is the distinct decrease in overall richness that lasts from the Selandian to the Ypresian. The Lutetian of West Central Africa is characterized by the first appearance of numerous cartilaginous and bony fishes. Our analysis of the ichthyofauna moreover indicates two periods of faunal exchanges: one during the Paleocene, where Central Africa appears to have been a source for the European marine fauna, and another during the Eocene when Europe was the source of the Central Africa fauna. These data indicate that Central Africa has had connections with the Tethyian realm. | Floréal Solé Corentin Noiret Delphine Desmares Sylvain Adnet Louis Taverne Thierry De Putter Florias Mees Johan Yans Thomas Steeman Stephen Louwye Annelise Folie Nancy J.Stevens Gregg F.Gunnell Daniel Baudet Nicole Kitambala Yaya Thierry Smith | 2019 | Geoscience Frontiers2019，10，3： | 0 |
