1Morphological observation and rbcL gene sequences studies of two new species,Grateloupia dalianensis H.W.Wang et D.Zhao,sp.nov.and G.yinggehaiensis H.W.Wang et R.X.Luan,sp.nov.(Halymeniaceae,Rhodophyta) from China显示文摘A few species in the genus Grateloupia (Halymeniaceae,Rhodophyta) have been investigated in detail with respect to morphological observations and molecular analyses.In this study,the authors document the vegetative and reproductive structures of two new species of Grateloupia,G.dalianensis H.W.Wang et D.Zhao,sp.nov.and G.yinggehaiensis H.W.Wang et R.X.Luan,sp.nov.They both have the morphological character that carpogonial ampullae and auxiliary cell ampullae are the simple Grateloupia-type.The two species can be distinguished from other species of the genus by their distinctive morphological features respectively.Based on ribulose-1,5-bisphosphate carboxylase/oxygenase (rbcL) gene sequences,the phylogenetic tree obtained in the study indicated that they are both embedded within the Grateloupia clade.G.dalianensis clusters a subclade with G.asiatica,and G.yinggehaiensis forms a single monophyletic subclade with G.hawaiiana.ZHAO Dan WANG Hongwei SHENG Yingwen LV Jianzhou LUAN Rixiao 2012Acta Oceanologica Sinica2012,31,2:20
2Molecular Cytogenetic Characterization and Stem Rust Resistance of Five Wheat-Thinopyrum ponticum Partial Amphiploids显示文摘Partial amphiploids created by crossing common wheat(Triticum aestivum L.) and Thinopyrum ponticum(Podp.) Barkworth & D.R.Dewey are important intermediates in wheat breeding because of their resistance to major wheat diseases.In this study,we examined the chromosome compositions of five Xiaoyan-series wheat-Th.ponticum partial amphiploids(Xiaoyan 68.Xiaoyan 693,Xiaoyan 784,Xiaoyan 7430,and Xiaoyan 7631) using GISH,multicolor-GISH.and multicolor-FISH.We found several chromosome changes in these lines.For example,wheat chromosomes 1B and 2B were added in Xiaoyan 68 and Xiaoyan 7430,respectively,while wheat chromosome6 B was eliminated from Xiaoyan 693 and Xiaoyan 7631.Chromosome rearrangements were also detected in these amphiploids.including an interspecific translocation involving chromosome 4D and some inlergenomic translocations,such as A-B and A-D translocations,among wheat genomes.Analysis of the Th.ponticum chromosomes in the amphiploids showed that some lines shared the same alien chromosomes.We also evaluated these partial amphiploids for resistance to nine races of stem rust,including TTKSK(commonly known as Ug99).Three lines,Xiaoyan 68,Xiaoyan 784,and Xiaoyan 7430,exhibited excellent resistance to ail nine races,and could therefore be valuable sources of stem rust resistance in wheat breeding.Qi Zheng Zhenling Lv Zhixia Niu Bin Li Hongwei Li Steven S.Xu Fangpu Han Zhensheng Li 2014Journal of Genetics and Genomics2014,41,11:9
3Function of note strings in Japanese Tit alarm calls to the Common Cuckoo:a playback experiment显示文摘Background: Birds produce alarm calls to convey information about threats. Some Passerine alarm calls consist of several note strings, but few studies have examined their function. Previous studies have shown that Japanese Tits(Parus minor) can alter the calling rate and number and combination of notes in response to predators. We previously found the combinations of note types in Japanese Tit alarm calls to be significantly different in response to the Sparrowhawk(Accipiter nisus) and Common Cuckoo(Cuculus canorus).Methods: Through playback experiments, we tested whether the note strings in Japanese Tit alarm calls to the Common Cuckoo have different functions in conveying information. The note strings of selected alarm calls were divided into the categories of C and D, and different calls were then constructed separately based on the two note string categories. Original alarm calls(C–D), C calls and D calls were played back to male Japanese Tits during the incubation period.Results: Male Japanese Tits had a significantly stronger response to C calls than to C–D calls, and they showed a significantly stronger response to both C and C–D calls than to D calls, suggesting that Japanese Tits discriminated between the C and D calls.Conclusions: Our study demonstrated that the C-and D-category note strings of Japanese Tit alarm calls to the Common Cuckoo have different functions, which supports the previous finding that different note strings in an alarm call can provide different information to receivers. However, the exact meanings of these note strings are not yet known, and further investigation is therefore required.Jiangping Yu Weiwei Lv Hongwei Xu Nehafta Bibi Yangyang Yu Yunlei Jiang Wei Liang Haitao Wang 2017Avian Research2017,8,3:8

5Evolution of a mining induced fracture network in the overburden strata of an inclined coal seam显示文摘The geological conditions of the Pingdingshan coal mining group were used to construct a physical model used to study the distribution and evolution of mining induced cracks in the overburden strata.Digital graphics technology and fractal theory are introduced to characterize the distribution and growth of the mining induced fractures in the overburden strata of an inclined coal seam.A relationship between fractal dimension of the fracture network and the pressure in the overburden strata is suggested.Mining induced fractures spread dynamically to the mining face and up into the roof as the length of advance increases.Moreover,the fractal dimension of the fracture network increases with increased mining length,in general,but decreases during a period from overburden strata separation until the main roof collapses.It is a1so shown that overburden strata pressure plays an important role in the evolution of mining induced fractures and that the fractal dimension of the fractures increases with the pressure of the overburden.Wei Xiujun Gao Mingzhong Lv Youchang Shi Xiangchao Gao Hailian Zhou Hongwei 2012International Journal of Mining Science and Technology2012,22,6:7
6Defect engineering of two-dimensional materials for efficient electrocatalysis显示文摘Exploring high-activity and earth-abundant electrocatalysts for electrochemical reactions,including the hydrogen evolution reaction(HER),oxygen reduction reaction(ORR)and oxygen evolution reaction(OER),etc.are crucial for building future large-scale green energy conversion and storage systems.Recently,some low-cost and resourceful two-dimensional(2D)semiconductor materials such as transition metal dichalcogenides(TMDCs)and layered oxides,have attracted increasing attention in electrocatalysis applications in virtue of their comparable catalytic activity and long-term stability to conventional noble metal-based catalysts(e.g.Pt/C,RuO_(2),IrO_(2),etc.).However,the intrinsic activity of some 2D materials still cannot meet the increasing requirement for highly efficient and reliable eletrocatalysts for future energy conversion and storage systems.In this context,designing elctrocatalysts with sufficient amount of active sites accessible for electrolyte,high activity of each active sites,and excellent conductivity is of great significance.To this end,defect engineering is a powerful strategy for tailoring the physical and chemical properties of 2D materials for efficient electrocatalysis.In this article,an overview of recent progress on defect engineering in 2D eletrocatalysts for HER,ORR and OER is presented.The effects of defects on the structure and tuned properties of 2D materials in eletrocatalysts applications are also summarized.Additionally,the challenges and opportunities ahead in this emerging field are also proposed.Hongwei Zhang Ruitao Lv 2018Journal of Materiomics2018,4,2:7
7Bruceine D inhibits HIF-1α-mediated glucose metabolism in hepatocellular carcinoma by blocking ICAT/β-catenin interaction显示文摘Hepatocellular carcinoma(HCC)is one of the leading causes of cancer-related deaths,characterized by highly hypoxic tumor microenvironment.Hypoxia-inducible factor-1α(HIF-1α)is a major regulator involved in cellular response to changes of oxygen levels,supporting the adaptation of tumor cells to hypoxia.Bruceine D(BD)is an isolated natural quassinoid with multiple anti-cancer effects.Here,we identified BD could significantly inhibit the HIF-1α expression and its subsequently mediated HCC cell metabolism.Using biophysical proteomics approaches,we identified inhibitor of β-catenin and T-cell factor(ICAT)as the functional target of BD.By targeting ICAT,BD disrupted the interaction of bcatenin and ICAT,and promoted β-catenin degradation,which in turn induced the decrease of HIF-1α expression.Furthermore,BD could inhibit HCC cells proliferation and tumor growth in vivo,and knockdown of ICAT substantially increased resistance to BD treatment in vitro.Our data highlight the potential of BD as a modulator of β-catenin/HIF-1α axis mediated HCC metabolism.Rui Huang Lijun Zhang Jinmei Jin Yudong Zhou Hongwei Zhang Chao Lv Dong Lu Ye Wu Hong Zhang Sanhong Liu Hongzhuan Chen Xin Luan Weidong Zhang 2021Acta Pharmaceutica Sinica B2021,11,11:4
8A super pan-genomic landscape of rice显示文摘Pan-genomes from large natural populations can capture genetic diversity and reveal genomic complexity.Using de novo longread assembly,we generated a graph-based super pan-genome of rice consisting of a 251-accession panel comprising both cultivated and wild species of Asian and African rice.Our pan-genome reveals extensive structural variations(SVs)and gene presence/absence variations.Additionally,our pan-genome enables the accurate identification of nucleotide-binding leucine-rich repeat genes and characterization of their inter-and intraspecific diversity.Moreover,we uncovered grain weight-associated SVs which specify traits by affecting the expression of their nearby genes.We characterized genetic variants associated with submergence tolerance,seed shattering and plant architecture and found independent selection for a common set of genes that drove adaptation and domestication in Asian and African rice.This super pan-genome facilitates pinpointing of lineage-specific haplotypes for trait-associated genes and provides insights into the evolutionary events that have shaped the genomic architecture of various rice species.Lianguang Shang Xiaoxia Li Huiying He Qiaoling Yuan Yanni Song Zhaoran Wei Hai Lin Min Hu Fengli Zhao Chao Zhang Yuhua Li Hongsheng Gao Tianyi Wang Xiangpei Liu Hong Zhang Ya Zhang Shuaimin Cao Xiaoman Yu Bintao Zhang Yong Zhang Yiqing Tan Mao Qin Cheng Ai Yingxue Yang Bin Zhang Zhiqiang Hu Hongru Wang Yang Lv Yuexing Wang Jie Ma Quan Wang Hongwei Lu Zhe Wu Shanlin Liu Zongyi Sun Hongliang Zhang Longbiao Guo Zichao Li Yongfeng Zhou Jiayang Li Zuofeng Zhu Guosheng Xiong Jue Ruan Qian Qian 2022Cell Research2022,32,10:3
9Non-dormant Axillary Bud 1 regulates axillary bud outgrowth in sorghum显示文摘Tillering contributes to grain yield and plant architecture and therefore is an agronomically important trait in sorghum(Sorghum bicolor).Here,we identified and functionally characterized a mutant of the Nondormant Axillary Bud 1(NAB1)gene from an ethyl methanesulfonate-mutagenized sorghum population.The nab1 mutants have increased tillering and reduced plant height.Map-based cloning revealed that NAB1encodes a carotenoid-cleavage dioxygenase 7(CCD7)orthologous to rice(Oryza sativa)HIGH-TILLERING DWARF1/DWARF17 and Arabidopsis thaliana MORE AXILLARY BRANCHING 3.NAB1 is primarily expressed in axillary nodes and tiller bases and NAB1 localizes to chloroplasts.The nab1 mutation causes outgrowth of basal axillary buds;removing these non-dormant basal axillary buds restored the wild-type phenotype.The tillering of nab1 plants was completely suppressed by exogenous application of the synthetic strigolactone analog GR24.Moreover,the nab1plants had no detectable strigolactones and displayed stronger polar auxin transport than wild-type plants.Finally,RNA-seq showed that the expression of genes involved in multiple processes,including auxin-related genes,was significantly altered in nab1.These results suggest that NAB1 functions in strigolactone biosynthesis and the regulation of shoot branching via an interaction with auxin transport.Jun Chen Limin Zhang Mengjiao Zhu Lijie Han Ya Lv Yishan Liu Pan Li Haichun Jing Hongwei Cai 2018Journal of Integrative Plant Biology2018,60,10:3

11Hierarchical red phosphorus incorporated TiO_(2) hollow sphere heterojunctions toward superior photocatalytic hydrogen production显示文摘Solar-to-hydrogen conversion through photocatalysis is a sustainable and promising strategy for storing solar energy.Recently,elemental red phosphorus(RP)with broad light absorption has been recognized as a potential candidate for photocatalytic hydrogen evolution,while challenges remain due to the rapid recombination of photogenerated carriers.In this work,RP modified TiO_(2)hollow spheres were designed and fabricated through the chemical vapor deposition method.The optimal hydrogen production rate reaching 215.5μmol/(g h)over TiO_(2)@RP heterostructure was obtained under simulated solar light irradiation.Experimental results evidenced that the hollow sphere structure and RP light absorber extended light absorption ability,and the heterostructure induced interfacial charge migration facilitated photoinduced charge separation,which benefited the photocatalytic hydrogen production performance.Guiqing Huang Wanneng Ye Chunxiao Lv Denys S.Butenko Chen Yang Gaolian Zhang Ping Lu Yan Xu Shuchao Zhang Hongwei Wang Yukun Zhu Dongjiang Yang 2022Journal of Materials Science & Technology2022,,13:3
12Redistributing Cu species in Cu-SSZ-13 zeolite as NH3-SCR catalyst via a simple ion-exchange显示文摘The nature and distribution of Cu species in Cu-SSZ-13 play a vital role in selective catalytic reduction of NO by NH3(NH3-SCR),but existing methods for adjusting the Cu distribution are complex and difficult to control.Herein,we report a simple and effective ion-exchange approach to regulate the Cu distribution in the one-pot synthesized Cu-SSZ-13 that possesses sufficient initial Cu species and thus provides a“natural environment”for adjusting Cu distribution precisely.By using this proposed strategy,a series of Cu-SSZ-13x zeolites with different Cu contents and distributions were obtained.It is shown that the dealumination of the as-synthesized Cu-SSZ-13 during the ion-exchange generates abundant vacant sites in the double six-membered-rings of the SSZ-13 zeolite for relocating Cu2+species and thus allows the redistribution of the Cu species.The catalytic results showed that the ion-exchanged Cu-SSZ-13 zeolites exhibit quite different catalytic performance in NH3-SCR reaction but superior to the parent counterpart.The structure–activity relationship analysis indicates that the redistribution of Cu species rather than other factors(e.g.,crystallinity,chemical composition,and porous structure)is responsible for the improved NH3-SCR performance and SO_(2) and H_(2)O resistance.Our work offers an effective method to precisely adjust the Cu distribution in preparing the industrial SCR catalysts.Ben Liu Nangui Lv Chan Wang Hongwei Zhang Yuanyuan Yue Jingdong Xu Xiaotao Bi Xiaojun Bao 2022Chinese Journal of Chemical Engineering2022,35,1:2
13MXR7 facilitates liver cancer metastasis via epithelial-mesenchymal transition显示文摘MXR7 is a cell-surface protein and highly expressed in hepatocellular carcinoma(HCC). The aim of this study is to determine the expression profile of MXR7 in HCC and investigate the influence of MXR7 on invasion and metastasis of HCC cells. For this purpose, immunohistochemical assay was used to identify the differential expression of MXR7 in 94 HCC specimens. Expression of MXR7 in 4 pairs of HCC and portal vein tumor thrombus(PVTT) was also tested. The motility of HCC cells were characterized by transwell migration and matrigel invasion assays. In vivo metastasis potential was determined via tail vein injection assay.Moreover, compared with noninvasive HCC tumors or human HCC cell lines with low metastatic potential, invasive HCC samples and HCC cell lines with high metastatic potential exhibited higher MXR7 expression. Furthermore, forced expression of MXR7 in SMMC-7721 promoted cell proliferation, migration and invasion in vitro and accelerated tumor growth and metastasis in vivo. Conversely, knockdown of MXR7 expression in HuH7 cells inhibited proliferation and motility of cells. Mechanically,overexpression of MXR7 promoted epithelial-mesenchymal transition(EMT) progress, and MXR7 depletion repressed the EMT phenotype. In conclusion, MXR7 is a mediator of EMT and metastasis in HCC and may serve as a novel therapeutic target.guishuai lv yexiong tan hongwei lv tian fang changzheng wang ting li yanting yu congli hu wen wen hongyang wang wen yang 2017Science China(Life Sciences)2017,60,11:2

18Two-Dimensional Tunable and Temperature-Insensitive Lyot Filter for FM-to-AM Compensation显示文摘Utilizing polarization maintaining photonic crystal fiber(PM-PCF)with the low temperature coefficient of birefringence,a two-dimensional tunable and temperature-insensitive Lyot filter aiming to compensate the frequency modulation to amplitude modulation(FM-to-AM)conversion in high power laser facility is demonstrated.The Jones matrix is applied to analyze the relationship between optical characteristics of the filter and physical parameters(including amplitude ratio,phase delay,and susceptibility of the birefringence to temperature)of the polarization optical field.Both the transmission peak wavelength and extinction ratio of the spectral transmission are able to be changed simultaneously,hence,it shows more efficient FM-to-AM compensation ability.Besides,the transmission peak shift is about 18pm/°C with the PM-PCF configuration,which is about two orders of magnitude less than the normal polarization maintaining fiber(PMF)configuration.The demonstrated filter presents a practical application potential in large scale laser driven facility.Mengqiu Fan Xiaocheng Tian Dandan Zhou Jiatian Wei Handing Xia Hongwei Lv Hao Zhao Dangpeng Xu Wanguo Zheng 2021Photonic Sensors2021,11,3:1
