| 1 | Potassium Uptake and Transport in Apple Roots Under Drought Stress显示文摘As one of the most important mineral nutrient elements, potassium(K^+) plays an important role in many plant physiological processes and determines both the yield and quality of crops. There are two typical gene families that regulate K^+transport in higher plants, including K^+channels and K^+transporters. However, little is known about how these channels and transporters divide their work in response to drought stress. In this study, the hydroponic experiment was conducted on Malus hupehensis. The K^+content was found to decrease in response to drought stress in M. hupehensis, the aboveground decreased by 34.15% and the underground decreased by 3.97%. Meanwhile, the root morphology change was detected by scanning the root system. Under conditions of drought, the genes encoding K^+transporters were upregulated including MdCHX1.3, MdCHX4.11, MdCHX4.8, MdCHX4.9, Md HKT1, and MdHAK3.2. The net influx of K^+was inhibited by 19.47% with the action of K^+channel inhibitors(CsCl), however a significant decrease(80.99%; P < 0.05) was found in roots exposed to a PM H+-ATPase(orthovanadate) inhibitor by utilizing a non-invasive micro-test technique. The trend of H+efflux was similar to that of K^+. The data suggested that the positive influx of K^+through the transporter accounted for the main K^+uptake under drought stress. These results suggest that we can improve the uptake of K^+by purposely up-regulating specific K^+transporters under drought stress. This process may improve growth, yield, quality, and stress tolerance in apple trees. | Jianguo Qi Simin Sun Lin Yang Mingjun Li Fengwang Ma Yangjun Zou | 2019 | Horticultural Plant Journal2019，5，1： | 6 |
| 2 | Face Masks in the New COVID-19 Normal: Materials, Testing,and Perspectives显示文摘The increasing prevalence of infectious diseases in recent decades has posed a serious threat to public health.Routes of transmission differ,but the respiratory droplet or airborne route has the greatest potential to disrupt social intercourse,while being amenable to prevention by the humble facemask.Different types of masks give different levels of protection to the user.The ongoing COVID-19 pandemic has even resulted in a global shortage of face masks and the raw materials that go into them,driving individuals to self-produce masks from household items.At the same time,research has been accelerated towards improving the quality and performance of face masks,e.g.,by introducing properties such as antimicrobial activity and superhydrophobicity.This review will cover mask-wearing from the public health perspective,the technical details of commercial and home-made masks,and recent advances in mask engineering,disinfection,and materials and discuss the sustainability of mask-wearing and mask production into the future. | Ming Hui Chua Weiren Cheng Shermin Simin Goh Junhua Kong Bing Li Jason Y.CLim Lu Mao Suxi Wang Kun Xue Le Yang Enyi Ye Kangyi Zhang Wun Chet Davy Cheong Beng Hoon Tan Zibiao Li Ban Hock Tan Xian Jun Loh | 2020 | Research2020，，1： | 5 |
| 3 | Occupational exposure to heavy metals, alcohol intake, and risk of type 2 diabetes and prediabetes among Chinese male workers显示文摘Objective: Both exposure to heavy metals and alcohol intake have been related to the risk of type 2 diabetes (T2D). In this study, we aimed to assess the potential interactions between metal exposure and alcohol intake on the risk of T2D and prediabetes in a cohort of Chinese male workers. Methods: We conducted a cross-sectional analysis of 26,008 Chinese male workers in an occupational cohort study from 2011 to 2013. We assessed metal exposure and alcohol consumption at baseline in these workers who were aged ≥20 years. Based on occupations which were categorized according to measured urine metal levels, multiple logistic regression analyses were used to evaluate the independent and joint effects of metal and alcohol exposure on the risk of T2D and prediabetes. Results: Risks of T2D (Ptrend= 0.0 0 1 ) and prediabetes (Ptrend = 0.001) were significantly elevated with increasing number of standard drinks per week, years of drinking, and lifetime alcohol consumption. An adjusted odds ratio (OR) of 6.1 (95% confidence interval [CI]: 4.8-7.8) was observed for the smelting/refining workers (highest metal exposure levels) who had the highest lifetime alcohol consumption (>873 kg)(Pinteraction = 0.018), whereas no statistically significant joint effect was found for prediabetes (Pinteraction =0.515). Conclusions: Both exposures to metal and heavy alcohol intake were associated with the risk of diabetes in this large cohort of male workers. There was a strong interaction between these two exposures in affecting diabetes risk that needs to be confirmed in future studies. | Ai-Min Yang Xiao-Bin Hu Simin Liu Ning Cheng De-Sheng Zhang Juan-Sheng Li Hai-Yan Li Xiao-Wei Ren Na Li Xi-Pin Sheng Jiao Ding Shan Zheng Min-Zheng Wang Tong-Zhang Zheng Ya-Na Bai | 2019 | Chronic Diseases and Translational Medicine2019，5，2： | 4 |
| 4 | Tectonics-palaeogeomorphology in rift basins: controlling effect on the sequence architecture显示文摘The relationship between deposition and tectonics of sedimentary basins has been a significant subject in recent years.Using typical rift basins such as the Nanpu Sag as an example,combined with the analysis of the tectonics-palaeogeomorphology of basins,we undertook a detailed study of the differences of the third-order sequences in different basins,the combination of depositional systems within the sequence framework and the distribution of depocenters and subsidence centers.Our results revealed a significant relationship between the tectonics-palaeogeomorphology of rift basins and the filling styles of sedimentary sequences.The basin structure plays a primary role in controlling the development of the third-order sequences and the boundary of these sequences is easily formed in basins with gentle slopes,shallow water and a small area.The characteristics of the tectonics-palaeogeomorphology of rift basins are dominated by half-grabens of extensional faults,which affect the temporal and spatial combination of sedimentary systems within the sequences as well as the distribution of depocenters and subsidence centers.Based on the development rules of the faults dominating the half-grabens of extensional faults,rift basins are classified into two types: the single fault segmented-linkage type and the multi-fault combination type.The main controlling factors of the temporal and spatial combination of sedimentary systems and the distribution of depocenters and subsidence centers in different basins are different.The characteristics of early segmentation and later linkage of the faults play a critical role in controlling the sedimentary system combination within the sequence framework and the temporal and spatial differences of depocenters and subsidence centers of the single fault segmented-linkage rift basins,while the differences in fault activities are the dominating factors of the multi-fault combination rift basins. | Ji Hancheng Jia Haibo Sun Simin Chen Liang Tang Yang Chen Wei Geng Yikai Zhou Hang | 2013 | Petroleum Science2013，10，4： | 3 |
| 5 | Development and characterization of novel microsatellite markers for the Common Pheasant(Phasianus colchicus)using RAD-seq显示文摘Background: The Common Pheasant(Phasianus colchicus) Linnaeus, 1758 is the most widespread pheasant in the world and widely introduced as a game bird. Increasing needs for conservation genetics and management of both wild and captive populations require permanent genetic resources, such as polymorphic microsatellites in order to genotype individuals and populations.Methods: In this study, 7598 novel polymorphic microsatellites for the Common Pheasant were isolated using a RAD-seq approach at an Illumina high-throughput sequencing platform. A panel of ten novel microsatellites and three existing ones from the chicken genome were multiplexed and genotyped on a set of 90 individuals of Common Pheasants(representing nine subspecies and ten individuals each) and 10 individuals of the Green Pheasant(P. versicolor).Results: These 13 microsatellites exhibited moderate to high levels of polymorphism, with the number of alleles per locus ranging from 2 to 8 and expected heterozygosities from 0.049 to 0.905. The first analysis of the genetic structure of subspecies/populations using a Bayesian clustering approach, implemented in STRUCTURE, showed two genetic clusters, corresponding to both the Green and the Common Pheasant, with further evidence of subpopulation structuring within the Common Pheasants.Conclusion: These markers are useful genetic tools for sustainable uses and evolutionary studies in these two Phasianus pheasants and probably other closely related game birds. | Biao Wang Xuan Xie Simin Liu Xuejing Wang Hong Pang Yang Liu | 2017 | Chinese Birds2017，，1： | 3 |
| 6 | Genome-wide identification and characterization of the lateral organ boundaries domain gene family in Brassica rapa var.rapa显示文摘The Lateral Organ Boundaries Domain(LBD)genes encode highly conserved plant-specific LOB domain proteins which regulate growth and development in various species.However,members of the LBD gene family have yet to be identified in Brassica rapa var.rapa.In the present study,fifty-nine LBD genes were identified and distributed on 10 chromosomes.The BrrLBD proteins are predicted to encode hydrophobic polypeptides between 118 and 394 amino acids in length and with molecular weights ranging from 13.31 to 44.24 kDa;the theoretical pi for these proteins varies from 4.83 to 9.68.There were 17 paralogous gene pairs in the BrrLBD family,suggesting that the amplification of the BrrLBD gene family involved largescale gene duplication events.Members of the BrrLBD family were divided into 7 subclades(class I a to e,class II a and b).Analysis of gene structure and conserved domains revealed that most BrrLBD genes of the same subclade had similar gene structures and protein motifs.The expression profiles of 59 BrrLBD genes were determined through Quantitative Real-time fluorescent PCR(qRT-PCR).Most BrrLBD genes in the same subclade had similar gene expression profiles.However,the expression patterns of 7 genes differed from their duplicates,indicating that although the gene function of most BrrLBD genes has been conserved,some BrrLBD genes may have undergone evolutionary change. | Qin Yu Simin Hu Jiancan Du Yongping Yang Xudong Sun | 2020 | Plant Diversity2020，42，1： | 3 |
| 7 | Cucurbit[10]uril-based chemistry显示文摘Cucurbit[n]urils(CB[n]s,n = 5-8,10,13-15) have been proven to be an interesting macrocyclic family with their distinctive molecular recognition properties and fascinating applications in fields such as catalysis,supramolecular materials, drug delivery and biological systems. With the biggest cavity in the CB[n]s family, CB[10] shows its unique molecular recognition properties that are rather distinctive from other CB[n]s. In this review, we summarize the progresses in CB[10]-based chemistry since CB[10] was first reported as CB[10] CB[5] complex in 2001. Purification, molecular recognition and supramolecular assembly of CB[10] will be described and an outlook will be given for further exploration of CB[10]-based chemistry. | Xiran Yang Fengbo Liu Zhiyong Zhao Feng Liang Haijun Zhang Simin Liu | 2018 | Chinese Chemical Letters2018，29，11： | 2 |

| 11 | Multi-3D hierarchical biomass-based carbon particles absorber for solar desalination and thermoelectric power generator显示文摘To meet challenges of the global energy crisis and the freshwater resources shortage,the interfacial solarto-steam conversion(ISSC)system was developed quickly in recent years.The photothermal materials play an important role in the ISSC system.We are devoted to developing a unique photothermal material integrating multiple 3 D design philosophy both at macroscopic and microscopic levels by employing the cost-effective and widespread resources like straw,rose and coffee grounds,for carbonization as solar absorbers.The biomass-based carbonized particles(CPs)possess three major advantages:(1)wide sizedistribution is accessible to form 3 D porous rough surface of absorber layer to enhance ability of light absorption;(2)the pristine hierarchical microstructure could absorb nearly all the incident light;(3)the intrinsic vascular bundles with pores on their lumen walls provide a rapid and omnidirectional transport for water and steam escape.A high-efficient solar steam device was fabricated based on the absorber material with its internal 3 D micro textures and external 3 D architectures.Under the illumination of 1 sun,the photothermal conversion efficiency of straw,rose and coffee CPs can reach 93.4%,92.8% and 76%,respectively.Simultaneously,a high-efficient solar thermoelectric generator(STEG)is made by coating CPs on a commercial thermoelectric generator and the maximum power of STEG can reach 538.0μW.Such scalable biomass-based photothermal materials and high-grade thermoelectric conversion capability could be applied to the water purification and the electricity production. | Hao Jiang Xuemin Geng Simin Li Hongyu Tu Jiliang Wang Lixia Bao Peng Yang Yanfen Wan | 2020 | Journal of Materials Science & Technology2020，59，24： | 1 |

| 13 | Chromatin-associated SUMOylation controls the transcriptional switch between plant development and heat stress responses显示文摘The post-translational protein modification known as SUMOylation has conserved roles in the heat stress responses of various species.The functional connection between the global regulation of gene expression and chromatin-associatedSUMOylation in plant cells isunknown.Here,weuncovereda genome-wide relationship between chromatin-associated SUMOylation and transcriptional switches in Arabidopsis thaliana grown at room temperature,exposed to heat stress,and exposed to heat stress followed by recovery.The small ubiquitin-like modifier(SUMO)-associated chromatin sites,characterized by whole-genome ChIP-seq,were generally associated with active chromatin markers.In response to heat stress,chromatin-associated SUMO signals increased at promoter-transcriptional start site regions and decreased in gene bodies.RNAseq analysis supported the role of chromatin-associatedSUMOylation in transcriptional activation during rapid responses to high temperature.Changes inSUMOsignals on chromatinwere associated with the upregulation of heat-responsivegenesandthedownregulation ofgrowth-relatedgenes.Disruption of theSUMOligasegene SIZ1 abolished SUMOsignals on chromatin and attenuated rapid transcriptional responses to heat stress.The SUMO signal peaks were enriched in DNA elements recognized by distinct groups of transcription factors under different temperature conditions.These observations provide evidence that chromatin-associated SUMOylation regulates the transcriptional switch between development and heat stress response in plant cells. | Danlu Han Chen Chen Simin Xia Jun Liu Jie Shu Vi Nguyen Jianbin Lai Yuhai Cui Chengwei Yang | 2021 | Plant Communications2021，2，1： | 1 |

| 17 | Factors Associated with SARS-CoV-2 Repeat Positivity—Beijing,China,June–September 2020显示文摘Introduction:Repeat positive severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)following COVID-19 initial viral clearance(repositivity)poses a public health management challenge.The objective was to determine factors associated with neutralizing antibody(Nab)level and re-positivity among patients infected with a single strain SARS-CoV-2.Methods:During a single strain SARS-CoV-2 cluster in Beijing,China,longitudinal individual clinical,virological,and immunological data were collected from 368 infections from June 13 to September 22,2020.Factors associated with Nab level and re-positivity were analyzed using generalized estimating equations.Results:A total of 353(96%)SARS-CoV-2 infections had demographic,clinical,and laboratory data available.Among the 353 infections,55(15.5%)were re-positive,and blood draws were taken from 346 individuals(98.0%)during hospitalization and/or during the follow-up period.Symptoms were milder for the second-time admission for the re-positives,although 36.4%of re-positives presented with radiographic appearance of pneumonia manifestation.Compared to non-re-positive patients,NAb titers were lower among re-positives;NAb was positively associated with clinical severity.Samples from the lower respiratory tract manifested higher viral load than that from the upper respiratory tract.Multivariable analysis showed re-positivity was positively associated with being female[odd ratio(OR)=1.7,95%confidence interval(CI)1.1–2.8]and being aged<18 years(OR=5.2,95%CI 1.5–18.1);having initially asymptomatic infection(OR=13.7,95%CI 1.6–116.3);and negatively associated with a higher NAb level(OR=0.9,95%CI 0.5–1.7).Conclusions:NAb may be important for sustained viral clearance.Lower respiratory tract infection was associated with higher viral load among all infections when compared to upper respiratory tract infection.Continuous lower respiratory and intermittent upper respiratory viral shedding among COVID-19 infections may occur. | Siqi Li Xiaoli Wang Li Li Yang Pan Siyuan Yang Dawei Tan Ying Shen Peng Yang Naor Bar-Zeev Yaling Hu Jacky MJennings Simin Li Linghang Wang Quanyi Wang | 2022 | China CDC weekly2022，4，5： | 1 |
