| 1 | Plant abiotic stress response and nutrient use efficiency显示文摘Abiotic stresses and soil nutrient limitations are major environmental conditions that reduce plant growth,productivity and quality.Plants have evolved mechanisms to perceive these environmental challenges,transmit the stress signals within cells as well as between cells and tissues,and make appropriate adjustments in their growth and development in order to survive and reproduce.In recent years,significant progress has been made on many fronts of the stress signaling research,particularly in understanding the downstream signaling events that culminate at the activation of stress-and nutrient limitation-responsive genes,cellular ion homeostasis,and growth adjustment.However,the revelation of the early events of stress signaling,particularly the identification of primary stress sensors,still lags behind.In this review,we summarize recent work on the genetic and molecular mechanisms of plant abiotic stress and nutrient limitation sensing and signaling and discuss new directions for future studies. | Zhizhong Gong Liming Xiong Huazhong Shi Shuhua Yang Luis R.Herrera-Estrella Guohua Xu Dai-Yin Chao Jingrui Li Peng-Yun Wang Feng Qin Jigang Li Yanglin Ding Yiting Shi Yu Wang Yongqing Yang Yan Guo Jian-Kang Zhu | 2020 | Science China(Life Sciences)2020，63，5： | 94 |
| 2 | Molecular Regulation of Plant Responses to Environmental Temperatures显示文摘Temperature is a key factor governing the growth and development,distribution,and seasonal behavior of plants.The entireplant life cycle is affected by environmental temperatures.Plants grow rapidly and exhibit specific changes in morphology under mild average temperature conditions,a response termed thermomorphogenesis.When exposed to chilling or moist chilling low temperatures,flowering or seed germination is accelerated in some plant species;these processes are known as vernalization and cold stratification,respectively.Interestingly,once many temperate plants are exposed to chilling temperatures for some time,they can acquire the ability to resist freezing stress,a process termed cold acclimation.In the face of global climate change,heat stress has emerged as a frequent challenge,which adversely affects plant growth and development.In this review,we summarize and discuss recent progress in dissecting them olecular mechanism sregulating plant thermomorphogenesis,vernalization,and responses to extreme temperatures.We also discuss the remaining issues that are crucial for understanding the interactions between plants and temperature. | Yanglin Ding Yiting Shi Shuhua Yang | 2020 | Molecular Plant2020，13，4： | 40 |

| 4 | Assessing Vulnerability to Drought Based on Exposure,Sensitivity and Adaptive Capacity:A Case Study in Middle Inner Mongolia of China显示文摘In this paper,we proposed a framework for evaluating the performance of ecosystem strategies prepared for enhancing vulnerability reduction in the face of hazards due to climate change.The framework highlights the positive effects of human activities in the coupled human and natural system(CHANS) by introducing adaptive capacity as an evaluation criterion.A built-in regional vulnerability to a certain hazard was generated based upon interaction of three dimensions of vulnerability:exposure,sensitivity and adaptive capacity.We illustrated the application of this framework in the temperate farming-grazing transitional zone in the middle Inner Mongolia of the northern China,where drought hazard is the key threat to the CHANS.Specific indices were produced to translate such climate variance and social-economic differences into specific indicators.The results showed that the most exposed regions are the inner land areas,while counties located in the eastern part are potentially the most adaptive ones.Ordos City and Bayannur City are most frequently influenced by multiple climate variances,showing highest sensitivity.Analysis also indicated that differences in the ability to adapt to changes are the main causes of spatial differences.After depiction of the spatial differentiations and analysis of the reasons,climate zones were divided to depict the differences in facing to the drought threats.The climate zones were shown to be similar to vulnerability zones based on the quantitative structure of indexes drafted by a triangular map.Further analysis of the composition of the vulnerability index showed that the evaluation criteria were effective in validating the spatial differentiation but potentially ineffective because of their limited time scope.This research will be a demonstration of how to combine the three dimensions by quantitative methods and will thus provide a guide for government to vulnerability reduction management. | LIU Xiaoqian WANG Yanglin PENG Jian Ademola K BRAIMOH YIN He | 2013 | Chinese Geographical Science2013，23，1： | 17 |
| 5 | Protein kinases in plant responses to drought, salt,and cold stress显示文摘Protein kinases are major players in various signal transduction pathways. Understanding the molecular mechanisms behind plant responses to biotic and abiotic stresses has become critical for developing and breeding climate-resilient crops. In this review,we summarize recent progress on understanding plant drought, salt, and cold stress responses, with a focus on signal perception and transduction by different protein kinases, especially sucrose nonfermenting1(SNF1)-related protein kinases(Sn RKs),mitogen-activated protein kinase(MAPK) cascades,calcium-dependent protein kinases(CDPKs/CPKs),and receptor-like kinases(RLKs). We also discuss future challenges in these research fields. | Xuexue Chen Yanglin Ding Yongqing Yang Chunpeng Song Baoshan Wang Shuhua Yang Yan Guo Zhizhong Gong | 2021 | Journal of Integrative Plant Biology2021，63，1： | 13 |
| 6 | Rice functional genomics:decades'efforts and roads ahead显示文摘Rice(Oryza sativa L.)is one of the most important crops in the world.Since the completion of rice reference genome sequences,tremendous progress has been achieved in understanding the molecular mechanisms on various rice traits and dissecting the underlying regulatory networks.In this review,we summarize the research progress of rice biology over past decades,including omics,genome-wide association study,phytohormone action,nutrient use,biotic and abiotic responses,photoperiodic flowering,and reproductive development(fertility and sterility).For the roads ahead,cutting-edge technologies such as new genomics methods,high-throughput phenotyping platforms,precise genome-editing tools,environmental microbiome optimization,and synthetic methods will further extend our understanding of unsolved molecular biology questions in rice,and facilitate integrations of the knowledge for agricultural applications. | Rongzhi Chen Yiwen Deng Yanglin Ding Jingxin Guo Jie Qiu Bing Wang Changsheng Wang Yongyao Xie Zhihua Zhang Jiaxin Chen Letian Chen Chengcai Chu Guangcun He Zuhua He Xuehui Huang Yongzhong Xing Shuhua Yang Daoxin Xie Yaoguang Liu Jiayang Li | 2022 | Science China(Life Sciences)2022，65，1： | 12 |
| 7 | Restorative effect and mechanism of mecobalamin on sciatic nerve crush injury in mice显示文摘Mecobalamin,a form of vitamin B12 containing a central metal element(cobalt),is one of the most important mediators of nervous system function.In the clinic,it is often used to accelerate recovery of peripheral nerves,but its molecular mechanism remains unclear.In the present study,we performed sciatic nerve crush injury in mice,followed by daily intraperitoneal administration of mecobalamin(65 μg/kg or 130 μg/kg) or saline(negative control).Walking track analysis,histomorphological examination,and quantitative real-time PCR showed that mecobalamin significantly improved functional recovery of the sciatic nerve,thickened the myelin sheath in myelinated nerve fibers,and increased the cross-sectional area of target muscle cells.Furthermore,mecobalamin upregulated m RNA expression of growth associated protein 43 in nerve tissue ipsilateral to the injury,and of neurotrophic factors(nerve growth factor,brain-derived nerve growth factor and ciliary neurotrophic factor) in the L4–6 dorsal root ganglia.Our findings indicate that the molecular mechanism underlying the therapeutic effect of mecobalamin after sciatic nerve injury involves the upregulation of multiple neurotrophic factor genes. | Lin Gan Minquan Qian Keqin Shi Gang Chen Yanglin Gu Wei Du Guoxing Zhu | 2014 | Neural Regeneration Research2014，9，22： | 11 |
| 8 | Using Impervious Surfaces to Detect Urban Expansion in Beijing of China in 2000s显示文摘The change of impervious surface area(ISA) can effectively reveal the gradual process of urbanization and act as a key index for monitoring urban expansion. Experiencing rapid growth of the built environment in the 2000 s, urban expansion of Beijing has not been fully characterized through ISA. In this study, Landsat TM images of Beijing in 2001 and 2009 were obtained, and the eight-year urban expansion process in Beijing was analyzed using the ISA extracted by means of the vegetation-imperious surface-soil(V-I-S) model. From the spatial variation in ISA, the ring structure of urban expansion in Beijing was significant during the study period, with decreasing urban density from the city center to the periphery. In the ring road analysis, the most dramatic changes of ISA were found between the fifth ring and the sixth ring. This area has experienced the most new residential development, and is currently the main source of urban expansion. The typical profile lines revealed the directional characteristics of urban expansion. The east-west profile was the most urbanized axes in Beijing, while ISA change in the east-north profile was more significant than in the other five profiles. Moreover, the transition matrix of ISA levels revealed an increase in urban density in the low density built areas; the Moran′s I index showed a clear expansion of the central urban area, which spread contiguously; and the standard deviational ellipse indicated the northeast was the dominant direction of urban expansion. These findings can provide important spatial control guidelines in the next round of national economic and social development planning, overall urban and rural planning, and land use planning. | PENG Jian LIU Yanxu SHEN Hong XIE Pan HU Xiaoxu WANG Yanglin | 2016 | Chinese Geographical Science2016，26，2： | 11 |
| 9 | Building a Cloud-Based Energy Storage System through Digital Transformation of Distributed Backup Battery in Mobile Base Stations显示文摘Battery energy storage systems(ESS) have been widely used in mobile base stations(BS) as the main backup power source. Due to the large number of base stations, massive distributed ESSs have largely stayed in idle and very difficult to achieve high asset utilization. In recent years, the fast-paced development of digital energy storage(DES) technology has revolutionized the traditional operation and maintenance of ESSs by transforming them into digital assets, further enabling battery energy storage services, raising up a new way to achieve a much higher utilization of such kind of largely idle ESS resources. In this paper, the disruptive DES technology will be introduced and its application under the context of mobile BSs will be studied, and then a cloud-based energy storage(CES) platform is proposed based on a large scale distributed DESs to provide a new cyber-enabled energy storage service to the local utility company. A real-world case study shows the effectiveness and efficiency of the CES platform. | Song Ci Yanglin Zhou Yuan Xu Xingjian Diao Junwei Wang | 2020 | China Communications2020，17，4： | 10 |
| 10 | Research Progress on Evaluation Frameworks of Regional Ecological Sustainability显示文摘As natural ecosystems provide the material basis and fundamental support for regional sustainable devel-opment,the sustainability of natural ecosystems is an important prerequisite and a viable approach for the achievement of regional sustainable development.It is also the final criteria to assess whether sustainable development paradigm is successful.Along with the increasing impacts of human activities on natural ecosystems,the evaluation of regional ecological sustainability has become one of the key issues for research on macro ecology and sustainable development.Based on different unit of indicators,this study firstly groups the evaluation frameworks of regional ecological sus-tainability into three major types:comprehensive index evaluation with dimensionless unit,monetary valuation,and biophysical quantity measurement.We then discuss and compare these types in terms of basic principles,scope of ap-plications,advantages and shortcomings.Finally,drawn on the discussion about characteristics of ecological sustain-ability,we outline the current trend and future directions of regional ecological sustainability evaluation,for instance,transition from sustainable development evaluation to sustainability science,integration of goal-oriented and problem-solving approaches,combination of spatial pattern analysis and ecological sustainability evaluation,and en-hancement of ecological sustainability evaluation at landscape scale. | PENG Jian WANG Yanglin WU Jiansheng SHEN Hong PAN Yajing | 2011 | Chinese Geographical Science2011，21，4： | 9 |
| 11 | Investigation of Myocardial Stunning after Cardiopulmonary Resuscitation in Pigs显示文摘Objective To investigate cardiac function and myocardial perfusion during 48 h after cardiopulmonary resuscitation (CPR), further to test myocardial stunning and seek indicators for long‐term survival after CPR. Methods After 4 min of untreated ventricular fibrillation, fifteen anesthetized pigs were studied at baseline and 2 h, 4 h, 24 h, and 48 h after restoration of spontaneous circulation (ROSC). Hemodynamic data, echocardiography and gated‐single photon emission computed tomography myocardial perfusion images were carried out. Results Mean arterial pressure (MAP), coronary perfusion pressure (CPP) and cardiac troponin I (CTNI) showed significant differences between eventual survival animals and non‐survival animals at 4 h after ROSC (109.2±10.7 mmHg vs. 94.8±12.3 mmHg, P=0.048; 100.8±6.9 mmHg vs. 84.4±12.6 mmHg, P=0.011; 1.60±0.13 ug/L vs. 1.75±0.10 ug/L, P=0.046). Mitral valve early‐to‐late diastolic peak velocity ratio, mitral valve deceleration time recovered 24 h; ejection faction and the summed rest score recovered 48 h after ROSC. Conclusion Cardiac systolic and early active relaxation dysfunctions were reversible within survival animals; cardiac stunning might be potentially adaptive and protective after CPR. The recovery of MAP, CPP, and CTNI could be the indicators for long‐term survival after CPR. | YANGLin LI ChunSheng GAO ChunJin WANG Shuo JI XianFei SU ZhiYu | 2011 | Biomedical and Environmental Sciences2011，24，2： | 8 |

| 14 | Spatial Process of Green Infrastructure Changes Associated with Rapid Urbanization in Shenzhen,China显示文摘Through a case study of Shenzhen City,China,this study focused on a quantitative method for analyzing the spatial processes involved in green infrastructure changes associated with rapid urbanization.Based on RS,GIS and SPSS statistics software,the approach includes selection of the square analysis units and representative landscape metrics,quantification of the change types of landscape metrics in all analysis units through two indices and hierarchical cluster analysis of the above analysis units with different landscape metric change types(i.e.spatial attributes).The analyses verify that there is a significant sequence of continuous changes in green infrastructure in Shenzhen.They are the perforation,the segmentation,the fragmentation,the evanescence and the filling-in processes,which have a good spatio-temporal correspondence with urbanization and reflect the synthetic influence of urban planning,government policies and landforms.Compared with other studies on quantifying the spatial pattern,this study provides an alternative probe into linking the spatial pattern to spatial processes and the corresponding ecological processes in the future.These spatio-temporal processes offer many opportunities for identifying,protecting and restoring key elements in an urban green infrastructure network for areas in the early stages of urbanization or for non-urbanized areas. | CHANG Qing LI Shuangcheng WANG Yanglin WU Jiansheng XIE Miaomiao | 2013 | Chinese Geographical Science2013，23，1： | 6 |

| 16 | The direct targets of CBFs:In cold stress response and beyond显示文摘Cold acclimation in Arabidopsis thaliana triggers a significant transcriptional reprogramming altering the expression patterns of thousands of cold-responsive(COR) genes. Essential to this process is the C-repeat binding factor(CBF)-dependent pathway, involving the activity of AP2/ERF(APETALA2/ethylene-responsive factor)-type CBF transcription factors required for plant cold acclimation. In this study, we performed chromatin immunoprecipitation assays followed by deep sequencing(ChIP-seq) to determine the genomewide binding sites of the CBF transcription factors. Cold-induced CBF proteins specifically bind to the conserved C-repeat(CRT)/dehydrationresponsive elements(CRT/DRE;G/ACCGAC) of their target genes. A Gene Ontology enrichment analysis showed that 1,012 genes are targeted by all three CBFs. Combined with a transcriptional analysis of the cbf1,2,3 triple mutant, we define 146 CBF regulons as direct CBF targets. In addition, the CBF-target genes are significantly enriched in functions associated with hormone, light,and circadian rhythm signaling, suggesting that the CBFs act as key integrators of endogenous and external environmental cues. Our findings not only define the genome-wide binding patterns of the CBFs during the early cold response, but also provide insights into the role of the CBFs in regulating multiple biological processes of plants. | Yue Song Xiaoyan Zhang Minze Li Hao Yang Diyi Fu Jian Lv Yanglin Ding Zhizhong Gong Yiting Shi Shuhua Yang | 2021 | Journal of Integrative Plant Biology2021，63，11： | 3 |
| 17 | Adult neural stem cells——Functional potential and therapeutic applications显示文摘The adult brain has been thought traditionally as a structure with a very limited regenerative capacity. It is now evident that neurogenesis in adult mammalian brain is a prevailing phenomenon. Neural stem cells with the ability to self-renew, differentiate into neurons, astrocytes and oligodendrocytes reside in some regions of the adult brain. Adult neurogenesis can be stimulated by many physiological factors including pregnancy. More strikingly, newborn neurons in hippocampus integrally function with local neurons, thus neural stem cells might play important roles in memory and learning function. It seems that neural stem cells could transdifferentiate into other tissues, such as blood cells and muscles. Although there are some impediments in this field, some attempts have been made to employ adult neural stem cells in the cell replacement therapy for traumatic and ischemic brain injuries. | YANGLin ZHUJianhong | 2004 | Progress in Natural Science:Materials International2004，14，2： | 3 |
| 18 | A cell wall-localized NLR confers resistance to Soybean mosaic virus by recognizing viral-encoded cylindrical inclusion protein.显示文摘Soybean mosaic virus (SMV) causes severe yield losses and seed quality reduction in soybean (Glycine max) production worldwide. Rsc4 from cultivar Dabaima is a dominant genetic locus for SMV resistance, and its mapping interval contains three Nucleotide-binding domain Leucine-rich Repeat containing (NLR) candidates (Rsc4-1, Rsc4-2, and Rsc4-3). The NLR-type resistant proteins were considered as important intracellular pathogen sensors in the previous studies. In this research, based on transient expression assay in Nicotiana benthamiana leaves, we found that the longest transcript of Rsc4-3 is sufficient to induce resistance response to SMV;and CRISPR/Cas9-mediated Rsc4-3 knockout in resistant cultivar Dabaima compromised the resistance. These indicate that Rsc4-3 confers resistance to SMV. Interestingly, Rsc4-3 encodes a cell wall localized NLR-type resistant protein (Rsc4-3). The internal polypeptide region responsible for apoplastic targeting of Rsc4-3 and the putative palmitoylation sites on the N-terminus are essential for the resistance response. Furthermore, we showed that viral-encoded cylindrical inclusion (CI) protein partially localizes to the cell wall and can interact with Rsc4-3. Virus-driven or transient expression of CI protein of avirulent SMV strains is enough to induce resistance response in the presence of Rsc4-3, suggesting that CI is the avirulent gene for Rsc4-3 mediated resistance. Our work exhibited a case of NLR recognizing virus in the apoplast and provided a simple and effective method for identifying resistant genes against SMV infection. | Jinlong Yin Liqun Wang Tongtong Jin Yang Nie Hui Liu Yanglin Qiu Yunhua Yang Bowen Li Jiaojiao Zhang Dagang Wang Kai Li Kai Xu Haijian Zhi | 2021 | Molecular Plant2021，14，11： | 2 |
| 19 | Pattern Dynamics of Thermal-environment Effect During Urbanization:A Case Study in Shenzhen City,China显示文摘The thermal-environment effect exists in the field of rapid urbanization.It has adverse effects on the urban atmosphere,regional climate,energy consumption,and public health.Shenzhen,a representative of rapidly urbanizing cities in China,was selected as a case for pattern dynamics analysis of the thermal environment.The surface temperature was acquired from the thermal infrared data of Landsat TM and ETM+ images in 1986,1995,and 2005 by Jiménez-Mu?oz and Sobrino's generalized single-channel method,which was used in assessing the distribution and spatial patterns of the thermal environment.The relative thermal environment curve(RTC) was combined with Moran's I analysis to assess the pattern dynamics of the thermal environment in different urbanization periods.Moran's I index and the RTC represent a process of aggregation-fragmentation-aggregation,which shows the aggregation pattern of a decrease during the rapid urbanization period and then an increase during the steady urbanization period.High-temperature areas gradually expanded to a uniform and scattered distribution in the rapid urbanization period;while the high thermal-environment effect was gradually transformed into a steady spatial pattern in the stable urbanization period.To characterize the increasing development in this multiple-center city,we chose profiles along an urban-development axis.The results suggest that heat islands have expanded from internal urban to external urban areas.Four profiles were obtained showing differences in shape due to spatial differences in the process of development. | XIE Miaomiao WANG Yanglin FU Meichen ZHANG Dingxuan | 2013 | Chinese Geographical Science2013，23，1： | 2 |
| 20 | Analysis of risk factors associated with endoscopic retrograde cholangiopancreatography for patients with liver cirrhosis: a multicenter, retrospective, clinical study显示文摘Background:Endoscopic retrograde cholangiopancreatography(ERCP)is the endoscopic modality of choice for the treatment of biliary and pancreatic diseases.However,patients with cirrhosis,particularly those with decompensated cirrhosis,are believed to be at increased risk for complications associated with ERCP.There is a paucity of literature describing the outcomes of ERCP for patients with cirrhosis.This study aimed to investigate the outcomes of ERCP for cirrhosis patients,especially adverse events,and evaluated its safety and efficacy.Methods:We performed a multicenter,retrospective study of all patients at Beijing Friendship Hospital affiliated to Capital Medical University,Xijing Hospital affiliated to Air Force Military Medical University,Beijing Youan Hospital affiliated to Capital Medical University,and the Fifth Medical Center of the People’s Liberation Army General Hospital from June 2003 to August 2019.The adverse events of inpatient ERCP for patients with(n=182)and without liver cirrhosis(controls;n=385)were compared.Results:A total of 567 patients underwent ERCP between January 2003 and December 2019 were enrolled in this study.Compared to patients without cirrhosis,patients with cirrhosis were at higher risk for postoperative complications(odds ratio[OR],4.172;95%confidence interval[CI],1.232–7.031;P<0.001)such as postoperative pancreatitis(OR,2.026;95%CI,1.002–4.378;P=0.001)and cholangitis(OR,3.903;95%CI,1.001–10.038;P=0.036).The main indications for ERCP for patients with cirrhosis in this study included choledocholithiasis(101 cases;55.5%),benign bile duct strictures(46 cases;25.3%),and malignant bile duct strictures(28 cases;15.4%).Among them,23 patients(12.6%)underwent balloon dilation and 79 patients(43.4%)underwent sphincterotomy.Of the patients with cirrhosis,delayed bleeding occurred in ten patients(5.5%),postoperative pancreatitis occurred in 80 patients(44.0%),and postoperative cholangitis occurred in 25 patients(13.7%).An additional multivariate analysis showed that the total bilirubin(TBIL)level(OR,4.58;95%CI,2.37–6.70)and Child-Pugh score of C(OR,3.11;95%CI,1.04–5.37)were risk factors for postoperative complications in patients with cirrhosis.Conclusions:Compared with the general population of patients undergoing ERCP,patients with cirrhosis were more prone to postoperative pancreatitis and cholangitis.TBIL levels and Child-Pugh scores were risk factors for postoperative complications in patients with cirrhosis. | Jielin Li Jiexuan Hu Peng Li Yongdong Wu Yongjun Wang Ming Ji Haiyang Hua Wenbin Ran Yanglin Pan Shutian Zhang | 2022 | Chinese Medical Journal2022，135，19： | 2 |
