2The evolution of Paleozoic vascular land plant diversity of South China显示文摘Data of Paleozoic and some Early Triassic vascular land plant fossils from South China are synthetically analyzed,revealing evolutionary characteristics of Paleozoic vascular land plant diversity.Vascular land plant diversity keeps increasing in the Paleozoic as a whole.The Silurian witnessed the earliest evolution and initial diversification of land plants.From the Early Devonian to the Early Carboniferous(Mississippian),the great development,diversification,and differentiation really occurred in vascular land plants,with fluctuations of diversity,rapid replacement of the plant types,and an all-out takeover of terrestrial ecological niches.From the Early Permian,land plant diversity dramatically increased,and reached a climax in the Middle-Late Permian.Comparisons between late Paleozoic marine and terrestrial biodiversity reveal co-evolution of the late Paleozoic animals and plants as well as the individual evolutionary patterns of sea/land ecosystems.Vascular land plant diversity dramatically declined in the Frasnian as a result of the F/F event,and the end-Permian mass extinctions completely turned over the phytogroups.Yi Wang Jun Wang HongHe Xu XueZhi He 2010Science China Earth Sciences2010,53,12:3
3Devonian integrative stratigraphy and timescale of China显示文摘The Global Boundary Stratotype Sections and Points(GSSPs) for the bases of all seven international Devonian stages have been formally defined and ratified by IUGS till 1996, and nowadays, the main tasks for Devonian stratigraphers include further subdivision of these standard stages, strictly constrained absolute ages for the boundaries, and precise neritic-pelagic and marine-terrestrial correlations using multidisciplinary stratigraphy methods. Establishment of high-resolution Devonian integrative stratigraphy framework and timescale of China would play an important role in improving regional and international correlation, facilitating the recognition of important stratigraphic levels in different paleogeographic settings, and understanding the evolution pattern of biota, paleoclimate and paleoenvironment during this critical interval. Based on well-studied bio-and chronostratigraphy of Devonian in South China and adjacent areas, in combination with recent achievements in carbon isotope stratigraphy, event stratigraphy and radioactive isotope ages, this paper briefly summarize the research history and current status of Devonian chronostratigraphy of China, and for the first time introduce Devonian integrative stratigraphy framework of China.Up to date, few studies have been conducted on the astronomical cyclostratigraphy and high-resolution radioactive isotope dating in Devonian of China, which should be our main focuses in the near future.Wenkun QIE Xueping MA Honghe XU Li QIAO Kun LIANG Wen GUO Junjun SONG Bo CHEN Jianfeng LU 2019Science China Earth Sciences2019,62,1:2

5Mutation in the gene encoding 1-aminocyclopropane-1-carboxylate synthase 4 (CitACS4) led to andromonoecy in watermelon显示文摘Although it has been reported previously that ethylene plays a critical role in sex determination in cucurbit species, how the andromonoecy that carries both the male and hermaphroditic flowers is determined in watermelon is still unknown. Here we showed that the watermelon gene 1-aminocyclopropane-1-carboxylate synthase 4(Cit ACS4), expressed specifically in carpel primordia, determines the andromonoecy in watermelon. Among four single nucleotide polymorphism(SNPs) and one InDel identified in the coding region of Cit ACS4, the C364 W mutation located in the conserved box 6 was cosegregated with andromonoecy. Enzymatic analyses showed that the C364 W mutation caused a reduced activity in Cit ACS4. We believe that the reduced Cit ACS4 activity may hamper the programmed cell death in stamen primordia, leading to the formation of hermaphroditic flowers.Gaojie Ji Jie Zhang Haiying Zhang Honghe Sun Guoyi Gong Jianting Shi Shouwei Tian Shaogui Guo Yi Ren Huolin Shen Junping Gao Yong Xu 2016Journal of Integrative Plant Biology2016,58,9:1

7GLTSCR1 coordinates alternative splicing and transcription elongation of ZO1 to regulate colorectal cancer progression显示文摘Alternative splicing(AS)and transcription elongation are vital biological processes,and their dysregulation causes multiple diseases,including tumors.However,the coregulatory mechanism of AS and transcription elongation in tumors remains unclear.This study demonstrates a novel AS pattern of tight junction protein 1(ZO1)regulated by the RNA polymerase II elongation rate in colorectal cancer(CRC).Glioma tumor suppressor candidate region gene 1(GLTSCR1)decreases the transcription elongation rate of ZO1 to provide a time window for binding of the splicing factor HuR to the specific motif in intron 22 of ZO1 and spliceosome recognition of the weak 3 and 5 splice sites in exon 23 to promote exon 23 inclusion.Since exon 23 inclusion in ZO1 suppresses migration and invasion of CRC cells,our findings suggest a novel potential therapeutic target for CRC.Fengyan Han Beibei Yang Mingyue Zhou Qiong Huang Minglang Mai Zhaohui Huang Maode Lai Enping Xu Honghe Zhang 2022Journal of Molecular Cell Biology2022,14,2:1
8An in-situ spectroscopy investigation of alkali metal interaction mechanism with the imide functional group显示文摘Organic anode materials have attracted considerable interest owing to their high tunability by adopting various active functional groups.However,the interaction mechanisms between the alkali metals and the active functional groups in host materials have been rarely studied systematically.Here,a widely used organic semiconductor of perylene-3,4,9,10-tetracarboxylic diimide(PTCDI)was selected as a model system to investigate how alkali metals interact with imide functional groups and induce changes in chemical and electronic structures of PTCDI.The interaction at the alkali/PTCDI interface was probed by in-situ X-ray photoelectron spectroscopy(XPS),ultraviolet photoelectron spectroscopy(UPS),synchrotron-based near edge X-ray absorption fine structure(NEXAFS),and corroborated by density functional theory(DFT)calculations.Our results indicate that the alkali metal replaces the hydrogen atoms in the imide group and interact with the imide nitrogen of PTCDI.Electron transfer induced gap states and downward band-bending like effects are identified on the alkali-deposited PTCDI surface.It was found that Na shows a stronger electron transfer effect than Li.Such a model study of alkali insertion/intercalation in PTCDI gives insights for the exploration of the potential host materials for alkali storage applications.Xu Lian Zhirui Ma Zhonghan Zhang Jinlin Yang Shuo Sun Chengding Gu Yuan Liu Honghe Ding Jun Hu Xu Cao Junfa Zhu Shuzhou Li Wei Chen 2020Nano Research2020,13,12:0

10Unraveling the advantages of Pd/CeO_(2)single-atom catalysts in the NO+CO reaction by model catalysts显示文摘Selective catalytic reduction of NO by CO is challenging in environmental catalysis but attractive owing to the advantage of simultaneous elimination of NO and CO.Here,model catalysts consisting of Pd nanoparticles(NPs)and single-atom Pd supported on a CeO_(2)(111)film grown on Cu(111)(denoted as Pd NPs/CeO_(2)and Pd_(1)/CeO_(2),respectively)were successfully prepared and characterized by synchrotron radiation photoemission spectroscopy(SRPES)and infrared reflection absorption spectroscopy(IRAS).The NO+CO adsorption/reaction on the Pd_(1)/CeO_(2)and Pd NPs/CeO_(2)catalysts were carefully investigated using SRPES,temperature-programmed desorption(TPD),and IRAS.It is found that the reaction products on both model catalysts are in good agreement with those on real catalysts,demonstrating the good reliability of using these model catalysts to study the reaction mechanism of the NO+CO reaction.On the Pd NPs/CeO_(2)surface,N_(2)is formed by the combination of atomic N coming from the dissociation of NO on Pd NPs at higher temperatures.N_(2)O formation occurs probably via chemisorbed NO combined with atomic N on the surface.While on the single-atom Pd_(1)/CeO_(2)surface,no N_(2)O is detected.The 100%N_(2)selectivity may stem from the formation of O-N-N-O^(*)intermediate on the surface.Through this study,direct experimental evidence for the reaction mechanisms of the NO+CO reaction is provided,which supports the previous density functional theory(DFT)calculations.Qian Xu Xingwang Cheng Ningqiang Zhang Yi Tu Lihui Wu Haibin Pan Jun Hu Honghe Ding Junfa Zhu Yadong Li 2023Nano Research2023,16,7:0
11Devonian integrative stratigraphy,biotas,and paleogeographical evolution of the Qinghai-Tibetan Plateau and its surrounding areas显示文摘The Devonian System in the Qinghai-Tibetan Plateau and its surrounding areas is widely distributed,diverse in lithotypes and rich in fossils.It records the crucial processes of continuous subduction and reduction of the Paleo-Asian Ocean in the northern hemisphere and the transformation of the Proto-Tethys Ocean into the Paleo-Tethys Ocean in the southern hemisphere.Thus,it is of great significance for explaining the global paleogeographic evolution,tectonic activities and biodiversity changes during this critical period.The blocks on both sides of the southern Tienshan suture zone and the Longmu Co-ShuanghuChangning-Menglian suture zone belong to different sedimentary systems and paleobiogeographic realms and regions,showing important tectonic paleogeographic partitioning significance.The two suture zones represent the main branches of the PaleoAsian Ocean and the Paleo-Tethys Ocean,respectively,and on this basis the Devonian System can be subdivided into three types:the Tienshan type,the Tethys type and the Gondwana type.Based on recent research progress on the Devonian stratigraphy and paleontology in combining provenance analysis and biotic characteristics in the Qinghai-Tibetan Plateau and surrounding areas,this paper aims to establish the latest integrative stratigraphic framework and conduct paleogeographic reconstruction,providing foundation for exploring the geological evolution and dynamic mechanisms of various terranes and blocks in the northern margin of Gondwana.The results indicate that the North Qiangtang,South Qiangtang,Simao,Baoshan and Tengchong terranes,as well as the Himalaya Tethys Zone and the South China Block have affinities with the Indian Block,while the Lhasa Terrane has affinities with the Australian Block,and may be located between the South China and Australian blocks.In the Emsian(Early Devonian),the South China Block separated from the northern margin of Gondwana,a process that was accompanied by the opening of the Jinshajiang-Ailaoshan Ocean.In the Middle Devonian,the mid-oceanic ridge of the Paleo-Tethys Ocean expanded rapidly,corresponding with a global sea-level rise,the widespread development of carbonate platforms and nadir values of Devonian seawater strontium isotopes.By the Late Devonian,the Paleo-Tethys Ocean had reached a considerable size,leading to abundant occurrences of Upper Devonian radiolarian cherts in the Paleo-Tethys suture zones.Wenkun QIE Kun LIANG Wen GUO Biao GAO Junjun SONG Bo CHEN Pu HUANG Li QIAO Honghe XU Jitao CHEN Yucong SUN Yichun ZHANG 2024Science China Earth Sciences2024,67,4:0
