| 2 | ECharts: A declarative framework for rapid construction of web-based visualization显示文摘While there have been a dozen of authoring systems and programming toolkits for visual design and development,users who do not have programming skills,such as data analysts or interface designers,still may feel cumbersome to efficiently implement a web-based visualization.In this paper,we present ECharts,an open-sourced,web-based,cross-platform framework that supports the rapid construction of interactive visualization.The motivation is driven by three goals:easy-touse,rich built-in interactions,and high performance.The kernel of ECharts is a suite of declarative visual design language that customizes built-in chart types.The underlying streaming architecture,together with a high-performance graphics renderer based on HTML5 canvas,enables the high expandability and performance of ECharts.We report the design,implementation,and applications of ECharts with a diverse variety of examples.We compare the utility and performance of ECharts with C3.js,HighCharts,and Chart.js.Results of the experiments demonstrate the efficiency and scalability of our framework.Since the first release in June 2013,ECharts has iterated 63 versions,and attracted over 22,000 star counts and over 1700 related projects in the GitHub.ECharts is regarded as a leading visualization development tool in the world,and ranks the third in the GitHub visualization tab. | Deqing Li Honghui Mei Yi Shen Shuang Su Wenli Zhang Junting Wang Ming Zu Wei Chen | 2018 | Visual Informatics2018，2，2： | 69 |
| 3 | clusterProfiler 4.0:A universal enrichment tool for interpreting omics data显示文摘Functional enrichment analysis is pivotal for interpreting highthroughput omics data in life science.It is crucial for this type of tool to use the latest annotation databases for as many organisms as possible.To meet these requirements,we present here an updated version of our popular Bioconductor package,clusterProfiler 4.0.This package has been enhanced considerably compared with its original version published 9 years ago.The new version provides a universal interface for functional enrichment analysis in thousands of organisms based on internally supported ontologies and pathways as well as annotation data provided by users or derived from online databases.It also extends the dplyr and ggplot2 packages to offer tidy interfaces for data operation and visualization.Other new features include gene set enrichment analysis and comparison of enrichment results from multiple gene lists.We anticipate that clusterProfiler 4.0 will be applied to a wide range of scenarios across diverse organisms. | Tianzhi Wu Erqiang Hu Shuangbin Xu Meijun Chen Pingfan Guo Zehan Dai Tingze Feng Lang Zhou Wenli Tang Li Zhan Xiaocong Fu Shanshan Liu Xiaochen Bo Guangchuang Yu | 2021 | The Innovation2021，2，3： | 40 |
| 4 | Exotic origin of the Chinese continental shelf: new insights into the tectonic evolution of the western Pacific and eastern China since the Mesozoic显示文摘The effect of paleo-Pacific subduction on the geological evolution of the western Pacific and continental China is likely complex. Nevertheless, our analysis of the distribution of Mesozoic granitoids in the eastern continental China in space and time has led us to an interesting conclusion: The basement of the continental shelf beneath East and South China Seas may actually be of exotic origin geologically unrelated to the continental lithosphere of eastern China. By accepting the notion that the Jurassic–Cretaceous granitoids in the region are genetically associated with western Pacific subduction and the concept that subduction may cease to continue only if the trench is being jammed, then the termination of the granitoidmagmatism throughout the vast region at *88 ± 2 Ma manifests the likelihood of ‘‘sudden'', or shortly beforehand(*100 Ma), trench jam of the Mesozoic western Pacific subduction. Trench jam happens if the incoming‘‘plate'' or portion of the plate contains a sizeable mass that is too buoyant to subduct. The best candidate for such a buoyant and unsubductable mass is either an oceanic plateau or a micro-continent. We hypothesize that the basement of the Chinese continental shelf represents such an exotic, buoyant and unsubductable mass, rather than seaward extension of the continental lithosphere of eastern China. The locus of the jammed trench(i.e., the suture) is predictably located on the shelf in the vicinity of, and parallel to, the arc-curved coastal line of the southeast continental China. It is not straightforward to locate the locus in the northern section of the East China Sea shelf because of the more recent(\20 Ma) tectonic re-organization associated with the opening of the Sea of Japan. We predict that the trench jam at *100 Ma led to the re-orientation of the Pacific plate motion in the course of NNW direction as inferred from the age-progressive Emperor Seamount Chain of Hawaiian hotspot origin(its oldest unsubdued Meiji and Detroit seamounts are *82 Ma),making the boundary between the Pacific plate and the newly accreted plate of eastern Asia a transform fault at the location east of the continental shelf of exotic origin. This explains the apparent *40 Myr magmatic gap from *88to *50 Ma prior to present-day western Pacific subduction initiation. We propose that basement penetration drilling on well-chosen sites is needed to test the hypothesis in order to reveal the true nature of the Chinese continental shelf basement. This testing becomes critical and cannot longer be neglected in order to genuinely understand the tectonic evolution of the western Pacific and its effect on the geology of eastern China since the Mesozoic, includingthe cratonic lithosphere thinning, related magmatism/mineralization, and the mechanism of the subsequent South China Sea opening, while also offering novel perspectives on aspects of the plate tectonics theory. We also suggest the importance of future plate tectonic reconstruction of the western Pacific to consider the nature and histories of the Chinese continental shelf of exotic origin as well as the probable transform plate boundary from *100 to*50 Ma. Effort is needed to reveal the true nature and origin of the *88 ± 2 Ma granitic gneisses in Taiwan and the 110–88 Ma granitoids on the Hainan Island. | Yaoling Niu Yi Liu Qiqi Xue Fengli Shao Shuo Chen Meng Duan Pengyuan Guo Hongmei Gong Yan Hu Zhenxing Hu Juanjuan Kong Jiyong Li Jinju Liu Pu Sun Wenli Sun Lei Ye Yuanyuan Xiao Yu Zhang | 2015 | Science Bulletin2015，60，18： | 32 |
| 5 | An assessment of global ocean wave energy resources over the last 45 a显示文摘Against the background of the current world facing an energy crisis,and human beings puzzled by the problems of environment and resources,developing clean energy sources becomes the inevitable choice to deal with a climate change and an energy shortage.A global ocean wave energy resource was reanalyzed by using ERA-40 wave reanalysis data 1957–2002 from European Centre for Medium-Range Weather Forecasts(ECMWF).An effective significant wave height is defined in the development of wave energy resources(short as effective SWH),and the total potential of wave energy is exploratively calculated.Synthetically considering a wave energy density,a wave energy level probability,the frequency of the effective SWH,the stability and long-term trend of wave energy density,a swell index and a wave energy storage,global ocean wave energy resources were reanalyzed and regionalized,providing reference to the development of wave energy resources such as wave power plant location,seawater desalination,heating,pumping. | ZHENG Chongwei SHAO Longtan SHI Wenli SU Qin LIN Gang LI Xunqiang CHEN Xiaobin | 2014 | Acta Oceanologica Sinica2014，33，1： | 22 |

| 7 | Genetic and biological characteristics of the globally circulating H5N8 avian influenza viruses and the protective efficacy offered by the poultry vaccine currently used in China显示文摘The H5N8 avian influenza viruses have been widely circulating in wild birds and are responsible for the loss of over 33 million domestic poultry in Europe, Russia, Middle East, and Asia since January 2020. To monitor the invasion and spread of the H5N8 virus in China, we performed active surveillance by analyzing 317 wild bird samples and swab samples collected from 41,172 poultry all over the country. We isolated 22 H5N8 viruses from wild birds and 14 H5N8 viruses from waterfowls. Genetic analysis indicated that the 36 viruses formed two different genotypes: one genotype viruses were widely detected from different wild birds and domestic waterfowls;the other genotype was isolated from a whopper swan. We further revealed the origin and spatiotemporal spread of these two distinct H5N8 virus genotypes in 2020 and 2021. Animal studies indicated that the H5N8 isolates are highly pathogenic to chickens, mildly pathogenic in ducks, but have distinct pathotypes in mice. Moreover, we found that vaccinated poultry in China could be completely protected against H5N8 virus challenge. Given that the H5N8 viruses are likely to continue to spread in wild birds, vaccination of poultry is highly recommended in high-risk countries to prevent H5N8 avian influenza. | Pengfei Cui Xianying Zeng Xuyong Li Yanbing Li Jianzhong Shi Conghui Zhao Zhiyuan Qu Yanwen Wang Jing Guo Wenli Gu Qi Ma Yuancheng Zhang Weipeng Lin Minghui Li Jingman Tian Dongxue Wang Xin Xing Yanjing Liu Shuxin Pan Yaping Zhang Hongmei Bao Liling Liu Guobin Tian Chengjun Li Guohua Deng Hualan Chen | 2022 | Science China(Life Sciences)2022，65，4： | 12 |
| 8 | Overexpression of a dominant-negative mutant of SIRT1 in mouse heart causes cardiomyocyte apoptosis and early-onset heart failure显示文摘SIRT1,a mammalian ortholog of yeast silent information regulator 2(Sir2),is an NAD+-dependent protein deacetylase that plays a critical role in the regulation of vascular function.The current study aims to investigate the functional significance of deacetylase activity of SIRT1 in heart.Here we show that the early postnatal hearts expressed the highest level of SIRT1deacetylase activity compared to adult and aged hearts.We generated transgenic mice with cardiac-specific expression of a dominant-negative form of the human SIRT1(SIRT1H363Y),which represses endogenous SIRT1 activity.The transgenic mice displayed dilated atrial and ventricular chambers,and died early in the postnatal period.Pathological,echocardiographic and molecular phenotype confirmed the presence of dilated cardiomyopathy.Terminal deoxynucleotidyl transferase-mediated dUTP nick-end-labeling analysis revealed a greater abundance of apoptotic nuclei in the hearts of transgenic mice.Furthermore,we show that cardiomyocyte apoptosis caused by suppression of SIRT1 activity is,at least in part,due to increased p53acetylation and upregulated Bax expression.These results indicate that dominant negative form of SIRT1(SIRT1H363Y)overexpression in mouse hearts causes cardiomyocyte apoptosis and early-onset heart failure,suggesting a critical role of SIRT1 in preserving normal cardiac development during the early postnatal period. | MU WenLi ZHANG QingJun TANG XiaoQiang FU WenYan ZHENG Wei LU YunBiao LI HongLiang WEI YuSheng LI Li SHE ZhiGang CHEN HouZao LIU DePei | 2014 | Science China(Life Sciences)2014，57，9： | 12 |
| 9 | Research and application on the technology system of multi-scale assessment of the impact on the atmospheric environment by urban planning显示文摘Improvement of the atmospheric environment in urban planning is an important issue to implement the sustainable development of cities. In this paper, in order to meet the demand of planning office to compare and assess quantitatively of the designs in multi-scale, based on geographical information system (GIS) data with high resolution, a multi-scale numerical modeling system for the atmospheric environment impact of urban planning is set up, and the multi-scale assessment index system is established, which compose the technology system of multi-scale assessment of the impact on the atmospheric environment by urban planning. In urban planning (urban development of Beijing) and optimizing layouts of Olympic Green, it has been applied to quantitatively evaluating the impact on atmospheric environment by urban planning before construction, which offers scientific foundation to optimize the whole and local urban layout. | WANG Guangtao, WANG Xiaoyun, MIAO Shiguang, JIANG Weimei, GUO Wenli, JI Chongping & CHEN Xianyan School of Architecture, Tsinghua University, Beijing 100084, China Ministry of Construction of China, Beijing 100044, China Beijing Meteorological Bureau, Beijing 100089, China Institute of Urban Meteorology, China Meteorological Administration, Beijing 100089, China Department of Atmospheric Sciences, Nanjing University, Nanjing 210093, China | 2005 | Science China Earth Sciences2005，48，z2： | 11 |

| 11 | Fe3O4/Au composite nano-particles and their optical properties显示文摘Fe3O4/Au composite particles with core/shell structure were prepared by reduction of Au3+ with hydroxylamine in the presence of an excess of Fe3O4 as seeds.The resultant col-loids,with an average diameter of less than 100 nm,were obtained;the remaining non-reacted Fe3O4 seeds can be removed by treatment with diluted HCl solution.The Fe3O4/Au colloids ex-hibit a characteristic peak of UV-visible spectra,which largely depend on the size of the particle and the suspension medium.The localized surface plasmon resonance peaks red shift and broaden with increased nanoparticle diameter or increased solvent ionic strength.The optical property is very important in the establishment of means for the detection of biomolecules. | CUI Yali HUI Wenli SU Jing WANG Yani CHEN Chao | 2005 | Science China Chemistry2005，48，4： | 8 |
| 12 | Mesoproterozoic to Paleozoic Nd isotope stratigraphy of the South China continental nucleus and its geological significance显示文摘The Yangtze continental nucleus in South China is situated in the Huangling-Shennongjia area in western Hubei Province.It comprises the early Precambrian crystalline basement and generally successive Proterozoic to Phanerozoic sedimentary covers.This paper reports a comprehensive Nd isotope study of fine-grained sedimentary rocks from the regional Mesoproterozoic to early Paleozoic strata.The Nd model ages display a V-shaped variation from ~2.5-2.8 Ga during the late Mesoproterozoic through ~1.5-1.7 Ga during the Neoproterozoic Nanhua Period to ~1.8-2.1 Ga during the Paleozoic Ordovician,with corresponding Nd (t) ranges of 11 to 14,1.1 to 5.3,and 7.9 to 9.9,respectively.This evolutionary trend broadly resembles those documented in the sedimentary strata along the southeastern margin of the Yangtze Craton and within the Jiangnan orogenic belt,indicating that the whole South China block underwent a mantle-input related tectono-magmatic event at ~0.8 Ga or earlier.However,the Huangling-Shennongjia area is discriminated from the other two regions by highly variable model ages (~1.5-2.7 Ga) and Nd (t) values (1.38-12.0) of the early Mesoproterozoic strata.Combined with the Archean model ages of the late Mesoproterozoic strata,it is suggested that the Mesoproterozoic sedimentary provenance of the Yangtze continental nucleus was distinct from that of the southeastern Yangtze Craton,likely indicative of an intervening aulacogen (or rift zone) or oceanic basin.In addition,the high comparability in Neoproterozoic to Paleozoic Nd isotope stratigraphy between the Yangtze Craton and the Jiangnan orogenic belt infers that the whole South China block had shared the same sedimentary basin and provenance since the Yangtze-Cathaysia welding at ~0.9 Ga.Thus,it is proposed that the Yangtze Craton had comprised a collage of micro-continents during the pre-Neoproterozoic until the Rodinia assemblage when the primitive South China block was formed. | BAI Xiao LING WenLi DUAN RuiChun QIU XiaoFei LIU ChengXin KUANG Hua GAO YongJuan ZHOU Lian CHEN ZiWan LU Shah-Song | 2011 | Science China Earth Sciences2011，54，11： | 8 |

| 15 | Characterization of 500 Chinese patients with cervical esophageal cancer by clinicopathological and treatment outcomes显示文摘Objective: There are no comprehensive studies on survival outcomes and optimal treatment protocols for cervical esophageal cancer(CEC), due to its rare clinical prevalence. Our objective was to determine the relationship between pathological characteristics, treatment protocols, and survival outcomes in Chinese CEC patients.Methods: A total of 500 Chinese CEC patients were selected from our 500,000 esophageal and gastric cardia carcinoma database(1973–2018). There were two main groups: patients treated with surgery, and patients receiving non-surgical treatments(radiotherapy, radiochemotherapy, and chemotherapy). The Chi-square test and Kaplan–Meier method were used to compare the continuous variables and survival.Results: Among the 500 CEC patients, 278(55.6%) were male, and the median age was 60.9 ± 9.4 years. A total of 496 patients(99.2%) were diagnosed with squamous cell carcinoma. In 171(34.2%) patients who received surgery, 22(12.9%) had undergone laryngectomy. In 322(64.4%) patients who received non-surgical treatments, 245(76.1%) received radiotherapy. Stratified survival analysis showed that only T stage was related with survival outcomes for CEC patients in the surgical group, and the outcomes between laryngectomy and non-laryngectomy patients were similar. It was noteworthy that the 5-year survival rate was similar in CEC patients among the different groups treated with surgery, radiotherapy, chemotherapy, or radiochemotherapy(P = 0.244). Conclusions: The CEC patients had similar survival outcomes after curative esophagectomy and radiotherapy, including those with or without total laryngectomy. These findings suggest that radiotherapy could be the initial choice for treatment of Chinese CEC patients. | Peinan Chen Xueke Zhao Fuyou Zhou Xin Song Shoujia Hu Yan Jin Xianzeng Wang Xuena Han ZongminFan Ran Wang Bei Li Wenli Han Panpan Wang Jilin Li Lixin Wan Liguo Zhang Qide Bao Fubao Chang Yanru Qin Zhiwei Chang Jianwei Ku Haijun Yang Ling Yuan Jingli Ren Xuemin Li Lidong Wang | 2020 | Cancer Biology & Medicine2020，17，1： | 6 |
| 16 | Adapting rice anther culture to gene transformation and RNA interference显示文摘Anther culture offers a rapid method of generating homozygous lines for breeding pro- gram and genetic analysis.To produce homozygous transgenic lines of rice(Oryza sativa L.)in one step,we developed an efficient protocol of anther-callus-based transformation mediated by Agro- bacterium after optimizing several factors influencing efficient transformation,including callus induc- tion and Agrobacterium density for co-cultivation.Using this protocol,we obtained 145 independent green transformants from five cultivars of japonica rice by transformation with a binary vector pCXK1301 bearing the rice gene,Xa21 for resistance to bacterial blight,of which 140 were further confirmed by PCR and Southern hybridization analysis,including haploids(32.1%),diploids(62.1%) and mixoploids(7.5%).Fifteen diploids were found to be doubled haploids,which accounted for 10.7%of the total positive lines.Finally,by including 28 from colchicine induced or spontaneous dip- loidization of haploids later after transformation,a total of 43 doubled haploids(30.7%)of Xa21 transgenic lines were obtained.We also generated two RNAi transgenic haploids of the rice Os- MADS2 gene,a putative redundant gene of OsMADS4 based on their sequence similarity,to inves- tigate its possible roles in rice flower development by this method.Flowers from the two OsMADS2 RNAi transgenic haploids displayed obvious homeotic alternations,in which lodicules were trans- formed into palea/lemma-like tissues,whereas identities of other floral organs were maintained.The phenotypic alternations were proved to result from specific transcriptional suppression of OsMADS2 gene by the introduced RNAi transgene.The results confirmed that OsMADS2 is involved in lodicule development of rice flower and functionally redundant with OsMADS4 gene.Our results demonstrated that rice anther culture could be adapted to gene transformation and RNAi analysis in rice. | CHEN Caiyan 1,2* ,XIAO Han 1,2* ,ZHANG Wenli 1,2 ,WANG Aiju 1,2 ,XIA Zhihui 1 ,LI Xiaobing 1 , ZHAI Wenxue 1 ,CHENG Zhukuan 1 &ZHU Lihuang 1 1.State Key Laboratory of Plant Genomics and National Center for Plant Gene Research,Institute of Genetics and Develop- mental Biology,Chinese Academy of Sciences,Beijing 100101,China 2.Graduate School of the Chinese Academy of Sciences,Beijing 100039,China | 2006 | Science China(Life Sciences)2006，49，5： | 5 |
| 17 | Preparation and characterization of Fe_(3)O_(4)/Au composite particles显示文摘Using Fe3O4 nano-particles as seeds, a new type of Fe3O4/Au composite particles with core/shell structure and diameter of about 170 nm was prepared by reduction of Au3+ with hydroxylamine in an aqueous solution. Particle size analyzer and transmission electron micro-scope were used to analyze the size distribution and microstructure of the particles in different conditions. The result showed that the magnetically responsive property and suspension stability of Fe3O4 seeds as well as reduction conditions of Au3+ to Au0 are the main factors which are crucial for obtaining a colloid of the Fe3O4/Au composite particles with uniform particle dispersion, excellent stability, homogeneity in particle sizes, and effective response to an external magnet in aqueous suspension solutions. UV-Vis analysis revealed that there is a characteristic peak of Fe3O4/Au fluid. For particles with d(0.5)=168 nm, the lmax is 625 nm. | CUI Yali HUI Wenli WANG Huirong WANG Lijun CHEN Chao | 2004 | Science China Chemistry2004，47，2： | 5 |
| 18 | The investigation for the relationship among serum leptin, erythrocyte membrane Ca^(2+)-ATPase activity and hypertensive disorder complicating pregnancy显示文摘Objective: To study the significance of Leptin and the activity of erythrocyte membrane Ca2+-ATPase(EMCA) in the development of hypertensive disorder complicating pregnancy. Methods: Radioimmunoassay was used to test the level of serum Leptin,and the activity of EMCA was determined chemically in 38 pregnant women with hypertensive disorder complicating pregnancy and 36 normotensive pregnant women. Results: The level of serum Leptin in hypertensive disorder complicating pregnancy(gestational hypertension: 13.76 ± 3.46 ng/ml; preeclampsia:15.76 ± 5.47 ng/ml; eclampsia: 18.32 ± 6.38 ng/ml)was significantly higher than that in normotensive pregnant women(11.33 ± 2.93 ng/ml),respectively. The average EMCA activity of patients with hypertensive disorder complicating pregnancy(gestational hypertension:1.65 ± 0.24 μmol·pi/mg·h ; preeclampsia:1.37 ± 0.19 μ mol·pi/mg·h; eclampsia:1.12 ± 0.14 μ mol·pi/mg·h) was significantly lower than that of normotensive pregnant women(1.83 ± 0.38 μ mol·pi/mg·h),respectively. There was a negative correlation between the level of serum Leptin and the activity of RMCA in hypertensive disorder complicating pregnancy(r = -0.63). Conclusion: Inhibition of EMCA activity of erythrocyte in hypertensive disorder complicating pregnancy may increase cytoplasmic free calcium, which contributes to the development of hypertensive disorder complicating pregnancy. The negative correlation between the level of serum Leptin and the activity of EMCA, also suggested that serum Leptin and the activity of EMCA may play a role in the development of hypertensive disorder complicating pregnancy. | Chunfang Li Wenli Gou Xuelian Chen Shuping Zhang | 2007 | Journal of Nanjing Medical University2007，21，3： | 4 |
| 19 | Coprinus comatus-derived nitrogen-containing biocarbon electrocatalyst with the addition of self-generating graphene-like support for superior oxygen reduction reaction显示文摘The development of nitrogen-rich biomassderived carbon catalysts provides an attractive perspective to substitute for Pt-based electrocatalysts for oxygen reduction reaction(ORR). We here report a facile strategy for synthesis of a nitrogen-doped biocarbon/graphene-like composite electrocatalyst by pyrolyzing a solid-state mixture of coprinus comatus biomass and melamine under nitrogen protection. The graphtic carbon nitride formed by polycondensation of melamine at 600 °C acts as a selfsacrificing template to generate the nitrogen-doped graphene-like sheet, which can function as an inserting agent and self-generating support. The composite catalyst exhibits the most promising catalytic activity towards the fourelectron ORR with a half-wave potential of around 0.83 V(vs. RHE), and more excellent stability and tolerance to methanol/ethanol compared to the commercial Pt/C catalyst. It is interestingly found that both a higher content of nitrogen and a larger ratio of graphitic-nitrogen species,which may derive from self-addition of graphene-like support into the catalyst, can effectively improve the electrocatalytic activity. The planar N group may be the nitrogen functionality that is most responsible for maintaining the ORR activity in alkaline medium. This study can largely encourage the exploration of high-performance carbon-based catalysts from economical and sustainable fungus biomass. | Chaozhong Guo Wenli Liao Zhongbin Li Lingtao Sun Haibo Ruan Qingshan Wu Qinghong Luo Jie Huang Changguo Chen | 2016 | Science Bulletin2016，61，12： | 4 |
| 20 | Transcriptome analysis provides insights into the regulation of metabolic processes during postharvest cold storage of loquat(Eriobotrya japonica)fruit显示文摘Loquat(Eriobotrya japonica)fruit accumulates lignin during postharvest storage under chilling conditions(0℃),while low-temperature conditioning(LTC;5℃for 6 days followed by transfer to 0℃)or heat treatment(HT;40℃for 4 h followed by transfer to 0℃)can alleviate lignification.Here we compared transcriptome profiles of loquat fruit samples under LTC or HT to those stored at 0℃at five time points from day 1 to day 8 after treatment.High-throughput transcriptome sequences were de novo assembled into 53,319 unique transcripts with an N50 length of 1306 bp.A total of 2235 differentially expressed genes were identified in LTC,and 1020 were identified in HT compared to 0℃.Key genes in the lignin biosynthetic pathway,including EjPAL2,EjCAD1,EjCAD3,4CL,COMT,and HCT,were responsive to LTC or HT treatment,but they showed different expression patterns during the treatments,indicating that different structural genes could regulate lignification at different treatment stages.Coexpression network analysis showed that these candidate biosynthetic genes were associated with a number of transcription factors,including those belonging to the AP2,MYB,and NAC families.Gene ontology(GO)enrichment analysis of differentially expressed genes indicated that biological processes such as stress responses,cell wall and lignin metabolism,hormone metabolism,and metal ion transport were significantly affected under LTC or HT treatment when compared to 0℃.Our analyses provide insights into transcriptome responses to postharvest treatments in loquat fruit. | Wenli Liu Jing Zhang Chen Jiao Xueren Yin Zhangjun Fei Qingbiao Wu Kunsong Chen | 2019 | Horticulture Research2019，6，1： | 3 |
