| 1 | Identification of a senescence-related protease in coriander leaves显示文摘Senescence-related protease may play an important role in leaf senescence. By improved SDS-Gela-tin-PAGE assay, a 63 ku senescence-related protease (63 SRP) in coriander leaves was identified. Activity of 63 SRP was increased in parallel to the advance of coriander leaf senescence, and inhibited by treating the leaf with gibberellic acid, and enhanced by ethylene treatment. The 63 SRP was suggested to be a serine protease based on the fact that its activity was inhibited by the protease inhibitor PMSF. The optimal temperature for the activity of the 70 ku protease was 50°C. The maximal activity was observed at pH 6-9, some activity could be observed on the gel slices incubated at pH 5 or 11. The 63 SRP was partly purified by the way of ammonium sulfate precipitation and then gel slicing after gel elec-trophoresis. | Weibo Jiang Xiangjuan Zhou Yumei Zhao Pengcheng Liu | 2002 | Chinese Science Bulletin2002，47，13： | 10 |
| 2 | Biodiversity-based development and evolution:the emerging research systems in model and non-model organisms显示文摘Evolutionary developmental biology,or Evo-Devo for short,has become an established field that,broadly speaking,seeks to understand how changes in development drive major transitions and innovation in organismal evolution.It does so via integrating the principles and methods of many subdisciplines of biology.Although we have gained unprecedented knowledge from the studies on model organisms in the past decades,many fundamental and crucially essential processes remain a mystery.Considering the tremendous biodiversity of our planet,the current model organisms seem insufficient for us to understand the evolutionary and physiological processes of life and its adaptation to exterior environments.The currently increasing genomic data and the recently available gene-editing tools make it possible to extend our studies to non-model organisms.In this review,we review the recent work on the regulatory signaling of developmental and regeneration processes,environmental adaptation,and evolutionary mechanisms using both the existing model animals such as zebrafish and Drosophila,and the emerging nonstandard model organisms including amphioxus,ascidian,ciliates,single-celled phytoplankton,and marine nematode.In addition,the challenging questions and new directions in these systems are outlined as well. | Long Zhao Feng Gao Shan Gao Yujun Liang Hongan Long Zhiyi Lv Ying Su Naihao Ye Liusuo Zhang Chengtian Zhao Xiaoyu Wang Weibo Song Shicui Zhang Bo Dong | 2021 | Science China(Life Sciences)2021，64，8： | 9 |
| 3 | Elevated plasma levels of selective cytokines in COVID-19 patients reflect viral load and lung injury显示文摘A recent outbreak of pneumonia in Wuhan,China was found to be caused by a 2019 novel coronavirus(2019-nCoV or SARS-CoV-2 or HCoV-19).We previously reported the clinical features of 12 patients with2019-n Co V infections in Shenzhen,China.To further understand the pathogenesis of COVID-19 and find better ways to monitor and treat the disease caused by 2019-n Co V,we measured the levels of 48 cytokines in the blood plasma of those 12 COVID-19 patients.Thirty-eight out of the 48 measured cytokines in the plasma of 2019-n Co V-infected patients were significantly elevated compared to healthy individuals.Seventeen cytokines were linked to 2019-nCoV loads.Fifteen cytokines,namely M-CSF,IL-10,IFN-α2,IL-17,IL-4,IP-10,IL-7,IL-1 ra,G-CSF,IL-12,IFN-γ,IL-1α,IL-2,HGF and PDGF-BB,were strongly associated with the lung-injury Murray score and could be used to predict the disease severity of2019-n Co V infections by calculating the area under the curve of the receiver-operating characteristics.Our results suggest that 2019-nCoV infections trigger extensive changes in a wide array of cytokines,some of which could be potential biomarkers of disease severity of 2019-n Co V infections.These findings will likely improve our understanding of the immunopathologic mechanisms of this emerging disease.Our results also suggest that modulators of cytokine responses may play a therapeutic role in combating the disease once the functions of these elevated cytokines have been characterized. | Yingxia Liu Cong Zhang Fengming Huang Yang Yang Fuxiang Wang Jing Yuan Zheng Zhang Yuhao Qin Xiaoyun Li Dandan Zhao Shunwang Li Shuguang Tan Zhaoqin Wang Jinxiu Li Chenguang Shen Jianming Li Ling Peng Weibo Wu Mengli Cao Li Xing Zhixiang Xu Li Chen Congzhao Zhou William J Liu Lei Liu Chengyu Jiang | 2020 | National Science Review2020，7，6： | 6 |
| 4 | Genome-and transcriptome-wide association studies provide insights into the genetic basis of natural variation of seed oil content in Brassica napus显示文摘Seed oil content(SOC)is a highly important and complex trait in oil crops.Here,we decipher the genetic basis of natural variation in SOC of Brassica napus by genome-and transcriptome-wide association studies using 505 inbred lines.We mapped reliable quantitative trait loci(QTLs)that control SOC in eight environments,evaluated the effect of each QTL on SOC,and analyzed selection in QTL regions during breeding.Six-hundred and ninety-two genes and four gene modules significantly associated with SOC were identified by analyzing population transcriptomes from seeds.A gene prioritization framework,POCKET(prioritizing the candidate genes by incorporating information on knowledge-based gene sets,effects of variants,genome-wide association studies,and transcriptome-wide association studies),was implemented to determine the causal genes in the QTL regions based on multi-omic datasets.A pair of homologous genes,BnPMT6s,in two QTLs were identified and experimentally demonstrated to negatively regulate SOC.This study provides rich genetic resources for improving SOC and valuable insights toward understanding the complex machinery that directs oil accumulation in the seeds of B.napus and other oil crops. | Shan Tang Hu Zhao Shaoping Lu Liangqian Yu Guofang Zhang Yuting Zhang Qing-Yong Yang Yongming Zhou Xuemin Wang Wei Ma Weibo Xie Liang Guo | 2021 | Molecular Plant2021，14，3： | 6 |
| 5 | Towards Flexible All-Carbon Electronics:Flexible Organic Field-Effect Transistors and Inverter Circuits Using Solution-Processed All-Graphene Source/Drain/Gate Electrodes显示文摘Flexible organic field-effect transistors(OFETs)using solution-processable functionalized graphene for all the electrodes(source,drain,and gate)have been fabricated for the first time.These OFETs show performance comparable to corresponding devices using Au electrodes as the source/drain electrodes on SiO2/Si substrates with Si as the gate electrode.Also,these devices demonstrate excellent flexibility without performance degradation over severe bending cycles.Furthermore,inverter circuits have been designed and fabricated using these all-graphene-electrode OFETs.Our results demonstrate that the long-sought dream for all-carbon and flexible electronics is now much closer to reality. | Yongsheng Chen Yanfei Xu Kai Zhao Xiangjian Wan Jiachun Deng Weibo Yan | 2010 | Nano Research2010，3，10： | 5 |
| 6 | Our recent progress in epigenetic research using the model ciliate, Tetrahymena thermophila显示文摘Epigenetic research focuses on heritable changes beyond the DNA sequence, which has led to a revolution in biologicalstudies and benefits in many other fields. The well-known model ciliate, Tetrahymena thermophila offers a unique system forepigenetic studies due to its nuclear dimorphism and special mode of sexual reproduction (conjugation), as well as abundantgenomic resources and genetic tools. In this paper, we summarize recent progress made by our research team and collaboratorsin understanding epigenetic mechanisms using Tetrahymena. This includes: (1) providing the first genome-wide basepair-resolution map of DNA N6-methyladenine (6mA) and revealed it as an integral part of the chromatin landscape;(2)dissecting the relative contribution of cis・ and trans- elements to nucleosome distribution by exploring the unique nucleardimorphism of Tetrahymena, (3) demonstrating the epigenetic controls of RNAi-dependent Polycomb repression pathwayson transposable elements, and (4) identifying a new histone monomethyltransferase, TXR1 (Tetrahymena Trithorax 1), thatfacilitates replication elongation through 让s substrate histone H3 lysine 27 monomethylation (H3K27mel). | Ting Cheng Yuanyuan Wang Jie Huang Xiao Chen Xiaolu Zhao Shan Gao Weibo Song | 2019 | Marine Life Science & Technology2019，1，1： | 4 |

| 8 | An inferred functional impact map of genetic variants in rice显示文摘Interpreting the functional impacts of genetic variants(GVs)is an important challenge for functional genomic studies in crops and next-generation breeding.Previous studies in rice(Oryza sativa)have focused mainly on the identification of GVs,whereas systematic functional annotation of GVs has not yet been performed.Here,we present a functional impact map of GVs in rice.We curated haplotype information for 17397026 GVs from sequencing data of 4726 rice accessions.We quantitatively evaluated the effects of missense mutations in coding regions in each haplotype based on the conservation of amino acid residues and obtained the effects of 918848 non-redundant missense GVs.Furthermore,we generated high-quality chromatin accessibility(CA)data from six representative rice tissues and used these data to train deep convolutional neural network models to predict the impacts of 5067405 GVs for CA in regulatory regions.We characterized the functional properties and tissue specificity of the GV effects and found that large-effect GVs in coding and regulatory regions may be subject to selection in different directions.Finally,we demonstrated how the functional impact map could be used to prioritize causal variants in mapping populations.This impact map will be a useful resource for accelerating gene cloning and functional studies in rice,and can be freely queried in RiceVarMap V2.0(http://gffzz90f9113514c343b0h6wc9wx966oxb6xx5.ffgz.tsg.suse.edu.cn). | Hu Zhao Jiacheng Li Ling Yang Gang Qin Chunjiao Xia Xingbing Xu Yangmeng Su Yinmeng Liu Luchang Ming Ling-Ung Chen Lizhong Xiong Weibo Xie | 2021 | Molecular Plant2021，14，9： | 3 |
| 9 | Exome sequencing reveals genetic architecture in patients with isolated or syndromic short stature显示文摘Short stature is among the most common endocrinological disease phenotypes of childhood and may occur as an isolated finding or in conjunction with other clinical manifestations.Although the diagnostic utility of clinical genetic testing in short stature has been implicated,the genetic architecture and the utility of genomic studies such as exome sequencing(ES)in a sizable cohort of patients with short stature have not been investigated systematically.In this study,we recruited 561 individuals with short stature from two centers in China during a 4-year period.We performed ES for all patients and available parents.All patients were retrospectively divided into two groups:an isolated short stature group(group I,n=257)and an apparently syndromic short stature group(group II,n=304).Causal variants were identified in 135 of 561(24.1%)patients.In group I,29 of 257(11.3%)of the patients were solved by variants in 24 genes.In group II,106 of 304(34.9%)patients were solved by variants in 57 genes.Genes involved in fundamental cellularprocess played an important role in the genetic architecture of syndromic short stature.Distinct genetic architectures and pathophysiological processes underlie isolated and syndromic short stature. | Xin Fan Sen Zhao Chenxi Yu Di Wu Zihui Yan Lijun Fan Yanning Song Yi Wang Chuan Li Yue Ming Baoheng Gui Yuchen Niu Xiaoxin Li Xinzhuang Yang Shiyu Luo Qiang Zhang Xiuli Zhao Hui Pan Mei Li Weibo Xia Guixing Qiu Pengfei Liu Shuyang Zhang Jianguo Zhang Zhihong Wu James R.Lupski Jennifer E.Posey Shaoke Chen Chunxiu Gong Nan Wu | 2021 | Journal of Genetics and Genomics2021，48，5： | 2 |
| 10 | A Multigrid Block LU-SGS Algorithm for Euler Equations on Unstructured Grids显示文摘We propose an efficient and robust algorithm to solve the steady Euler equa- tions on unstructured grids.The new algorithm is a Newton-iteration method in which each iteration step is a linear multigrid method using block lower-upper symmetric Gauss-Seidel(LU-SGS)iteration as its smoother To regularize the Jacobian matrix of Newton-iteration,we adopted a local residual dependent regularization as the replace- ment of the standard time-stepping relaxation technique based on the local CFL number The proposed method can be extended to high order approximations and three spatial dimensions in a nature way.The solver was tested on a sequence of benchmark prob- lems on both quasi-uniform and local adaptive meshes.The numerical results illustrated the efficiency and robustness of our algorithm. | Ruo Li Xin Wang Weibo Zhao | 2008 | Numerical Mathematics(Theory,Methods and Applications)2008，1，1： | 2 |
| 11 | Variation of diffuse attenuation coefficient of downwelling irradiance in the Arctic Ocean显示文摘The diffuse attenuation coefficient(Kd) for downwelling irradiance is calculated from solar irradiance data measured in the Arctic Ocean during 3rd and 4th Chinese National Arctic Research Expedition(CHINARE), including 18 stations and nine stations selected for irradiance profiles in sea water respectively. In this study, the variation of attenuation coefficient in the Arctic Ocean was studied, and the following results were obtained. First, the relationship between attenuation coefficient and chlorophyll concentration in the Arctic Ocean has the form of a power function. The best fit is at 443 nm, and its determination coefficient is more than 0.7. With increasing wavelength, the determination coefficient decreases abruptly. At 550 nm, it even reaches a value lower than 0.2. However, the exponent fitted is only half of that adapted in low-latitude ocean because of the lower chlorophyll-specific absorption in the Arctic Ocean. The upshot was that, in the case of the same chlorophyll concentration, the attenuation caused by phytoplankton chlorophyll in the Arctic Ocean is lower than in low-latitude ocean. Second, the spectral model, which exhibits the relationship of attenuation coefficients between 490 nm and other wavelength, was built and provided a new method to estimate the attenuation coefficient at other wavelength, if the attenuation coefficient at 490 nm was known. Third, the impact factors on attenuation coefficient, including sea ice and sea water mass, were discussed. The influence of sea ice on attenuation coefficient is indirect and is determined through the control of entering solar radiation. The linear relationship between averaging sea ice concentration(ASIC, from 158 Julian day to observation day) and the depth of maximum chlorophyll is fitted by a simple linear equation. In addition, the sea water mass, such as the ACW(Alaskan Coastal Water), directly affects the amount of chlorophyll through taking more nutrient, and results in the higher attenuation coefficient in the layer of 30–60 m. Consequently, the spectral model of diffuse attenuation coefficient, the relationship between attenuation coefficient and chlorophyll and the linear relationship between the ASIC and the depth of maximum chlorophyll, together provide probability for simulating the process of diffuse attenuation coefficient during summer in the Arctic Ocean. | WANG Weibo ZHAO Jinping | 2014 | Acta Oceanologica Sinica2014，33，6： | 2 |

| 17 | Blunt chest impact leading to acute myocardial infarction in a young man: a rare finding of both coronary artery dissection and pseudoaneurysm显示文摘To the editor:A 22-year-old man was admitted without significant heart complaint,but with a diagnosis of myocardial infarction at a local hospital.Two months earlier,he suffered blunt chest impact and maxillofacial trauma due to an accident falling from a 3-meterhigh balcony.He has previously been healthy without any family history of disease.Physical examination on admission revealed mandibular tenderness and a traumatic blindness in the left eye.Electrocardiogram demonstrated significant ST segment elevation in V1.5,abnormally Q waves and inverted T waves in V2-5 (Figure 1A).Coronary angiography (CAG) demonstrated a pseudoaneurysm originating from the distal segment of the left main coronary artery (LMCA) and dissection in ostial/proximal left anterior descending artery (LAD) with severe stenosis (about 90%) with TIMI 3 flow (Figure 1B).For interventional treatment,CAG was repeated one week later.Surprisingly,the results showed that LAD stenosis significantly reduced to 65%,while the size of pseudoaneurysm was the same,indicating no need for intervention (Figure 1C).Under medical treatment with aspirin,clopidogrel and beta-blocker,his clinical condition was stable,only with slight shortness of breath.Eight months after the trauma,myocardial magnetic resonance were performed,indicating decreased left ventricular function with ejection fraction of 28.6% (end-diastolic volume 192.5 ml,end-systolic volume 137.5 ml,stroke volume 55.0 ml),and transmural myocardial scarring in the anterior wall and apex. | Zhao Weibo Li Yonghua Hu Houyuan | 2014 | Chinese Medical Journal2014，，17： | 1 |
| 18 | Laboratory Diagnosis and Monitoring the Viral Shedding of SARS-CoV-2 Infection显示文摘The worldwide epidemic of coronavirus disease 2019(COVID-19)is ongoing.Rapid and accurate detection of the causative virus SARSCoV-2 is vital for the treatment and control of COVID-19.In this study,the comparative sensitivity of different respiratory specimen types were retrospectively analyzed using 3,552 clinical samples from 410 COVID-19 patients confirmed by Guangdong CDC(Center for Disease Control and Prevention).Except for bronchoalveolar lavage fluid(BALF),the sputum possessed the highest positive rate(73.4%–87.5%),followed by nasal swabs(53.1%–85.3%)for both severe and mild cases during the first 14 days after illness onset(d.a.o.).Viral RNA could be detected in all BALF samples collected from the severe group within 14 d.a.o.and lasted up to 46 d.a.o.Moreover,although viral RNA was negative in the upper respiratory samples,it was also positive in BALF samples in most cases from the severe group during treatment.Notably,no viral RNA was detected in BALF samples from the mild group.Despite typical ground-glass opacity observed via computed tomographic scans,no viral RNA was detected in the first three or all upper respiratory tract specimens from some COVID-19 patients.In conclusion,sputum is most sensitive for routine laboratory diagnosis of COVID-19,followed by nasal swabs.Detection of viral RNA in BALF improves diagnostic accuracy in severe COVID-19 patients. | Yang Yang Minghui Yang Jing Yuan Fuxiang Wang Zhaoqin Wang Jinxiu Li Mingxia Zhang Jinli Wei Ling Peng Gary Wong Haixia Zheng Weibo Wu Chenguang Shen Mingfeng Liao Kai Feng Jianming Li Qianting Yang Juanjuan Zhao Lei Liu Yingxia Liu | 2020 | The Innovation2020，1，3： | 1 |
