2Wheat breeding history reveals synergistic selection of pleiotropic genomic sites for plant architecture and grain yield显示文摘Diversity surveys of crop germplasm are important for gaining insights into the genomic basis for plant architecture and grain yield improvement,which is still poorly understood in wheat.In this study,we exome sequenced 287 wheat accessions that were collected in the past 100 years.Population genetics analysis identified that 6.7%of the wheat genome falls within the selective sweeps between landraces and cultivars,which harbors the genes known for yield improvement.These regions were asymmetrically distributed on the A and B subgenomes with regulatory genes being favorably selected.Genome-wide association study(GWAS)identified genomic loci associated with traits for yield potential,and two underlying genes,TaARF12 encoding an auxin response factor and TaDEP1 encoding the G-proteinγ-subunit,were located and characterized to pleiotropically regulate both plant height and grain weight.Elite single-nucleotide haplotypes with increased allele frequency in cultivars relative to the landraces were identified and found to have accumulated over the course of breeding.Interestingly,we found that TaARF12 and TaDEP1 function in epistasis with the classical plant height Rht-1 locus,leading to propose a“Green Revolution”-based working model for historical wheat breeding.Collectively,our study identifies selection signatures that fine-tune the gibberellin pathway during modern wheat breeding and provides a wealth of genomic diversity resources for the wheat research community.Aili Li Chenyang Hao Zhenyu Wang Shuaifeng Geng Meiling Jia Fang Wang Xiang Han Xingchen Kong Lingjie Yin Shu Tao Zhongyin Deng Ruyi Liao Guoliang Sun Ke Wang Xingguo Ye Chengzhi Jiao Hongfeng Lu Yun Zhou Dengcai Liu Xiangdong Fu Xueyong Zhang Long Mao 2022Molecular Plant2022,15,3:4
3New FeNiCrMo(P, C, B) high-entropy bulk metallic glasses with unusual thermal stability and corrosion resistance显示文摘New Fe(20–35) Ni(20) Cr(20–30) Mo(5–15)(P(0.6) C(0.2) B(0.2))(20) bulk metallic glasses with excellent thermal stability,strength, and corrosion resistance have been developed through the high-entropy alloy design strategy.The high-entropy bulk metallic glasses(HE-BMGs) possess larger supercooled liquid regions of ~69 K,higher crystallization onset temperatures of ~852 K, larger undercoolings of ~109 K, and more sluggish crystallization process upon heating than the conventional metallic glass benefited from the high mixing entropy effect. The HE-BMGs also exhibit ultrahigh strength of ~3.4 GPa, Vickers hardness of ~1107,and superior corrosion resistance in acids and Na Cl solutions by formation of highly stable Cr-and Moenriched passive films. The new metal-metalloid HE-BMG system and exceptional properties give the alloys good promise for both scientific and engineering applications.Yanhui Li Siwen Wang Xuewei Wang Meiling Yin Wei Zhang 2020Journal of Materials Science & Technology2020,36,8:2
4Experimental Wave Attenuation Study over Flexible Plants on a Submerged Slope显示文摘Using plants is a kind of environmentally-friendly coastal protection to attenuate wave energy. In this paper, a set of experiments were conducted to investigate the wave attenuation performance using flexible grasses on a submerged slope, and the wave attenuation coefficient for these experiments was calculated for different still water depths, slope and grass configurations. It was found that the slope plays a significant role in wave attenuation. The wave attenuation coefficient increases with increasing relative row number and relative density. For a small relative row number, the two configurations from the slope top to its toe and from the slope toe to its top performed equally to a large extent. For a medium relative row number, the configuration from the slope toe to its top performed more poorly than that from the slope top to its toe; however, it performed better than that from the slope top to its toe for a high relative row number. With a single row of grasses close to the slope top from the slope toe, the wave attenuation coefficient shows double peaks. With increasing grass rows or still water depth, the grass location corresponding to the maximum wave attenuation coefficient is close to the slope top. The dimensional analysis and the least square method were used to derive an empirical equation of the wave attenuation coefficient considering the effect of relative density, the slope, the relative row number and the relative location of the middle row, and the equation was validated to experimental data.YIN Zegao YANG Xiaoyu XU Yuanzhao DING Meiling LU Haixiang 2017Journal of Ocean University of China2017,16,6:1
5Sheet Bulk Forming of Thin-Walled Components with External Gearing through Upsetting Using Controllable Deformation Zone Method显示文摘Sheet-bulk metal forming(SBMF)is a promising process for manufacturing complex sheet components with functional elements.In this study,the entire forming process for a typical thin-walled component with external gearing is investigated,including sheet forming and bulk forming processes.Deep drawn cups are prepared during sheet forming;subsequently,upsetting is performed on the sidewall to form external gearing.The upsetting method performed is known as upsetting with a controllable deformation zone(U-CDZ).Compared with the conventional upsetting method,a floating counter punch with a counter force is used in the U-CDZ method such that the forming mechanism is changed into the accumulation of the deformation zone instead of deformation throughout the entire sidewall.The effects of the counter force and material flow are investigated to understand the mechanism.The forming quality,i.e.,the formfilling and effective strain distribution,improved,whereas a high forming load is avoided.In addition,a punch with a lock bead is used to prevent folding at the inner corner during the experiment.Xincun Zhuang Meile Liang Shengfa Zhu Yin Zhu Zhen Zhao 2021Chinese Journal of Mechanical Engineering2021,34,5:1
6Cytotoxic effects of docetaxel as a candidate drug of drug-eluting stent on human umbilical vein endothelial cells and the signaling pathway of cell migration inhibition,adhesion delay and shape change显示文摘Docetaxel(DTX),a paclitaxel analogue,can efficiently inhibit proliferation of vascular smooth muscle cells and has broadly been used as an antiangiogenesis drug.However,as a candidate drug of drug-eluting stent,the effects of DTX on human umbilical vein endothelial cells(HUVECs)are still not well understood.Herein,we investigated the effects of DTX on proliferation,apoptosis,adhesion,migration and morphology of HUVECs in vitro.We found that DTX had the cytostatic and cytotoxic effects at low and high concentrations,respectively.DTX could inhibit the proliferation and migration of HUVECs,induce HUVECs apoptosis,delay HUVECs adhesion and decrease spreading area and aspect ratio of individual cells.The signaling pathway that DTX led to the migration inhibition,adhesion delay and shape change of HUVECs is the VE-cadherin mediated integrin b1/FAK/ROCK signaling pathway.The study will provide a theoretical basis for the clinical application of DTX.Tingzhang Hu Chun Yang Meiling Fu Jiali Yang Rolin Du Xiaolin Ran Tieying Yin Guixue Wang 2017Regenerative Biomaterials2017,4,3:1
7An engineered xCas12i with high activity,high specificity,and broad PAM range显示文摘Dear Editor,The clustered regularly interspaced short palindromic repeats-Cas(CRISPR-Cas)systems,including type II Cas9 and type V Cas12 systems,which serve in the adaptive immunity of prokaryotes against viruses,have been developed into genome-editing tools(Anzalone et al.,2020;Doudna,2020).Compared with type II systems,the type V systems including V-A to V-K showed more functional diversity(Yan et al.,2019).Amongst them,Cas12i has a relatively smaller size(1,033-1,093 aa),compared to SpCas9 and Cas12a,and has a 5'-TTN protospacer adjacent motif(PAM)preference(Yan et al.,2019).Hainan Zhang Xiangfeng Kong Mingxing Xue Jing Hu Zikang Wang Yinghui Wei Haoqiang Wang Jingxing Zhou Weihong Zhang Mengqiu Xu Xiaowen Shen Fengcai Yin Zhiyuan Ai Guangyan Huang Junhui Xia Xueqiong Song Hengbin Li Yuan Yuan Jinhui Li Na Zhong Meiling Zhang Yingsi Zhou Hui Yang 2023Protein & Cell2023,14,7:0
8Human 8-cell embryos enable efficient induction of disease-preventive mutations without off-target effect by cytosine base editor显示文摘Approximately 140 million people worldwide are homozygous carriers of APOE4(ε4),a strong genetic risk factor for late onset familial and sporadic Alzheimer’s disease(AD),91%of whom will develop AD at earlier age than heterozygous carriers and noncarriers.Susceptibility to AD could be reduced by targeted editing of APOE4,but a technical basis for controlling the off-target effects of base editors is necessary to develop low-risk personalized gene therapies.Here,we first screened eight cytosine base editor variants at four injection stages(from 1-to 8-cell stage),and found that FNLS-YE1 variant in 8-cell embryos achieved the comparable base conversion rate(up to 100%)with the lowest bystander effects.In particular,80%of AD-susceptibleε4 allele copies were converted to the AD-neutralε3 allele in humanε4-carrying embryos.Stringent control measures combined with targeted deep sequencing,whole genome sequencing,and RNA sequencing showed no DNA or RNA off-target events in FNLS-YE1-treated human embryos or their derived stem cells.Furthermore,base editing with FNLS-YE1 showed no effects on embryo development to the blastocyst stage.Finally,we also demonstrated FNLS-YE1 could introduce known protective variants in human embryos to potentially reduce human susceptivity to systemic lupus erythematosus and familial hypercholesterolemia.Our study therefore suggests that base editing with FNLS-YE1 can efficiently and safely introduce known preventive variants in 8-cell human embryos,a potential approach for reducing human susceptibility to AD or other genetic diseases.Yinghui Wei Meiling Zhang Jing Hu Yingsi Zhou Mingxing Xue Jianhang Yin Yuanhua Liu Hu Feng Ling Zhou Zhifang Li Dongshuang Wang Zhiguo Zhang Yin Zhou Hongbin Liu Ning Yao Erwei Zuo Jiazhi Hu Yanzhi Du Wen Li Chunlong Xu Hui Yang 2023Protein & Cell2023,14,6:0
9Atmospheric heterogeneous reaction of chlorobenzene on mineralα-Fe_(2)O_(3)particulates:a chamber experiment study显示文摘Despite the large emission of chlorinated volatile organic compounds(CVOCs)into the atmosphere,the ultimate fate of these compounds remains largely unknown.Herein,we explore the photochemical conversion of an important class of CVOCs,namely chlorobenzene(CB),on mineralα-Fe_(2)O_(3)particulates under atmospheric relevant conditions.A series of chamber reactions composed of the CB with/without SO_(2)or NO_(2)are performed,followed by in situ diffuse reflectance infrared Fourier transform spectroscopy measurements and density functional theory calculations.We show that CB can be considerably degraded byα-Fe_(2)O_(3)under light irradiation,whereas the reaction is markedly suppressed by adding SO_(2)or NO_(2)owing to their competitive adsorption and surface acidification.In particular,we discover that CB can be ultimately converted into polychlorinated dibenzo-p-dioxins and dibenzofurans(PCDD/Fs)under dark state or light irradiation,suggesting a possible origin of atmospheric PCDD/Fs from this overlooked photochemical source.Meiling Chen Mengjie Yin Yuetan Su Ruizhe Li Kezhou Liu Zhongbiao Wu Xiaole Weng 2023Frontiers of Environmental Science & Engineering2023,17,11:0
10Elevated Atmospheric CO_(2)Reduced Antibiotics Accumulation in Rice Grains and Soil ARGs Abundance in Multiple Antibiotics-contaminated Paddy Fields显示文摘Antibiotic resistance genes(ARGs)as new pollutants have become a global environmental pollution problem in recent years.Elevated atmospheric CO_(2) is one of the major factors affecting global climate change.But,the impacts of elevated CO_(2) on soil ARGs in multiple antibiotics-contaminated paddy soils are largely unknown.In this study,six antibiotics including sulfadiazine(SDZ),sulfamethoxazole(SMZ),tetracycline(TC),oxytetracycline(OTC),enrofloxacin(ENR),and ciprofloxacin(CIP)were selected to investigate their combined effects on rice biomass,antibiotics accumulation,soil bacterial community and ARGs under elevated CO_(2) levels.Results showed that elevated CO_(2) significantly reduced the accumulation of SMZ,OTC,ENR,and CIP in rice grains by 18.98%,20.07%,41.73%,and 44.25%,respectively.Elevated CO_(2) could affect soil microbialβ-diversity,and tend to reduce the microbial functions of human diseases,organismal systems,and genetic information processing.In addition,elevated CO_(2) significantly decreased the abundance of sulfonamide ARGs,tetracycline ARGs,and quinolone ARGs by 19.59%,18.58%,and 28.96%,respectively,while increased that of multidrug ARGs by 11.54%.Overall,this study emphasized that elevated CO_(2) may mitigate the threat of antibiotics contamination to rice food security but aggravate the environmental risk of multidrug ARGs in soil,contributing to a better understanding of the consequences of elevated CO_(2) levels on food security and soil ecological health in multiple antibiotics-contaminated paddy fields.WANG Yabo XU Meiling WANG Xiaojie AI Fuxun DU Wenchao YIN Ying JI Rong GUO Hongyan 2023Chemical Research in Chinese Universities2023,39,3:0
11Biomarker-targeted fluorescent probes for breast cancer imaging显示文摘Breast cancer has become a common tumor worldwide which seriously endangers people's health. Early diagnosis and treatment are particularly urgent in order to reduce the onset risk, mortality, and prolong the five-year survival rate. Therefore, we need a kind of diagnosis and treatment technology with high speci ficity, sensitivity and selectivity. In recent years, because of its unique properties in biological applications, fluorescence imaging has become an attractive research subject. Fluorescence imaging offers innovative ideas of targetable recognition of breast cancer cells, breast cancer imaging in vivo animal models, anticancer drugs delivery for guiding the mammary surgery via a noninvasive way with high sensitively and speci fically. In this review, we summarized the recent advances offluorescent probes for breast cancer imaging, which were classi fied according to different biomarkers the probes recognized.Moreover, we discussed the strengths, built-in problems as well as the challenges about the fluorescent probe as a unique potential method for the better application in breast cancer diagnosis and treatment.Dongfang Yue Meiling Wang Fei Deng Wenting Yin Haidong Zhao Xiaoming Zhao Zhaochao Xu 2018Chinese Chemical Letters2018,29,5:0
12Excimer Formation of Perylene Bisimide Dyes within Stacking-Restrained Folda-Dimers:Insight into Anomalous Temperature Responsive Dual Fluorescence显示文摘We have fabricated a new perylene bisimide(PBI)folda-dimer(BPBI-CB-1)by tethering two PBI moieties to the ortho-carbon positions of a carborane unit.The synthesized compound adopted distinct configurations in different solvents with dual emissions as its characteristic.The two PBI moieties in the molecule appeared either in a weakly interacted,monomer-like state or brought into close π-π contact with each other,forming an interacted stacking state.The equilibrium between these two states was governed by the nature of solvents and testing temperature.Spectroscopic and theoretical studies concluded that dual emission bands originated from intramolecular monomer-like and stacking states,respectively.Remarkably,in a solvent like 1,2-dichloroethane(DCE),both emission intensities increased with rising temperatures.The positive temperature response of the monomer emission was ascribed to an increased amount of monomer-like population,owing to its endothermic energy state,while the excimer emission was rationalized by increased population of the bright exciton state,resulting in an increased emission yield that compensated the diminished population of the stacking state.To our knowledge,this is the first report on positive temperature-responsive dual emissions associated with the synergism of intramolecular intersubunit aggregation/dissociation and excimer transformation.Congdi Shang Gang Wang Yu-Chen Wei Qingwei Jiang Ke Liu Meiling Zhang Yi-Yun Chen Xingmao Chang Fengyi Liu Shiwei Yin Pi-Tai Chou Yu Fang 2022CCS Chemistry2022,4,6:0
