| 1 | Progress in Semi-arid Climate Change Studies in China显示文摘This article reviews recent progress in semi-arid climate change research in China.Results indicate that the areas of semiarid regions have increased rapidly during recent years in China,with an increase of 33%during 1994-2008 compared to 1948-62.Studies have found that the expansion rate of semi-arid areas over China is nearly 10 times higher than that of arid and sub-humid areas,and is mainly transformed from sub-humid/humid regions.Meanwhile,the greatest warming during the past 100 years has been observed over semi-arid regions in China,and mainly induced by radiatively forced processes.The intensity of the regional temperature response over semi-arid regions has been amplified by land-atmosphere interactions and human activities.The decadal climate variation in semi-arid regions is modulated by oceanic oscillations,which induce land-sea and north-south thermal contrasts and affect the intensities of westerlies,planetary waves and blocking frequencies.In addition,the drier climates in semi-arid regions across China are also associated with the weakened East Asian summer monsoon in recent years.Moreover,dust aerosols in semi-arid regions may have altered precipitation by affecting the local energy and hydrological cycles.Finally,semi-arid regions in China are projected to continuously expand in the 21st century,which will increase the risk of desertification in the near future. | Jianping HUANG Jieru MA Xiaodan GUAN Yue LI Yongli HE | 2019 | Advances in Atmospheric Sciences2019，36，9： | 15 |
| 2 | Bph30confers resistance to brown planthopperby fortifying sclerenchyma in rice leaf sheaths显示文摘Phloem-feeding insects cause massive losses in agriculture and horticulture.Host plant resistance to phloem-feeding insects is often mediated by changes in phloem composition,which deter insect settling and feeding and decrease viability.Here,we report that rice plant resistance to the phloem-feeding brown planthopper(BPH)is associated with fortification of the sclerenchyma tissue,which is located just beneath the epidermis and a cell layer or two away from the vascular bundle in the rice leaf sheath.We found that BPHs prefer to feed on the smooth and soft region on the surface of rice leaf sheaths called the long-cell block.We identified Bph30 as a rice BPH resistance gene that prevents BPH stylets from reaching the phloem due to the fortified sclerenchyma.Bph30 is strongly expressed in sclerenchyma cells and enhances cellulose and hemicellulose synthesis,making the cell walls stiffer and sclerenchyma thicker.The structurally fortified sclerenchyma is a formidable barrier preventing BPH stylets from penetrating the leaf sheath tissues and arriving at the phloem to feed.Bph30 belongs to a novel gene family,encoding a protein with two leucine-rich domains.Another member of the family,Bph40,also conferred resistance to BPH.Collectively,the fortified sclerenchyma-mediated resistance mechanism revealed in this study expands our understanding of plant-insect interactions and opens a new path for controlling planthoppers in rice. | Shaojie Shi Huiying Wang Lingyun Nie Di Tan Cong Zhou Qian Zhang YiLi Bo Du Jianping Guo Jin Huang DiWu Xiaohong Zheng Wei Guan Junhan Shan Lili Zhu Rongzhi Chen Longjian Xue Linda L.Walling Guangcun He | 2021 | Molecular Plant2021，14，10： | 7 |
| 3 | Investigating different bio-responses of the upper ocean to Typhoon Haitang using Argo and satellite data显示文摘The responses of the upper ocean to Typhoon Haitang in July 2005 are investigated using Argo float and multiplatform satellite data.The results show decreasing sea surface temperature(SST),a deepening of the mixed layer depth(MLD),and enhanced Chlorophyll-a(Chl-a)concentration.Two extreme cool regions are identified.While the magnitude of SST cooling in the two regions is similar,the biological response(Chla enhancement)differs.To facilitate comparisons,the region to the northeast of Taiwan is defined as region A and the region east of Taiwan as region B.Ekman pumping and the intrusion of the Kuroshio play an important role in the enhancement of Chl-a in region A.Cold eddies provide the material source for the formation of the cold center in region B,where mixing is dominant.Because of the relatively high translation speed(5 m/s)in region B,Ekman pumping has little influence on the cooling and Chl-a enhancement processes.Moreover,the MLD is shallower than the nutricline,which means that mixing does not result in a marked increase in nutrients in the euphotic layer(where the nutrient concentration is uniformly depleted).Sea temperatures,in contrast,gradually decrease with depth below the bottom of the mixed layer.In contrast to region A,region B showed no significant enhancement of Chl-a but strong SST cooling. | Haixia Shan Yuping Guan Jianping Huang | 2014 | Chinese Science Bulletin2014，59，8： | 6 |
| 4 | Changes in Aridity in Response to the Global Warming Hiatus显示文摘The global warming slowdown or warming hiatus, began around the year 2000 and has persisted for nearly 15 years. Most studies have focused on the interpretation of the hiatus in temperature. In this study, changes in a global aridity index(AI) were analyzed by using a newly developed dynamical adjustment method that can successfully identify and separate dynamically induced and radiatively forced aridity changes in the raw data. The AI and Palmer Drought Severity Index produced a wetting zone over the mid-to-high latitudes of the Northern Hemisphere in recent decades. The dynamical adjustment analysis suggested that this wetting zone occurred in response to the global warming hiatus. The dynamically induced AI(DAI) played a major role in the AI changes during the hiatus period,and its relationships with the North Atlantic Oscillation(NAO), Pacific Decadal Oscillation(PDO), and Atlantic Multi-decadal Oscillation(AMO) also indicated that different phases of the NAO, PDO, and AMO contributed to different performances of the DAI over the Northern Hemisphere. Although the aridity wetting over the mid-to-high latitudes may relieve long-term drying in certain regions, the hiatus is temporary, and so is the relief. Accelerated global warming will return when the NAO, PDO, and AMO revert to their opposite phases in the future, and the wetting zone is likely to disappear. | Xiaodan GUAN Jianping HUANG Ruixia GUO | 2017 | Journal of Meteorological Research2017，31，1： | 5 |
| 5 | Impact of oceans on climate change in drylands显示文摘Drylands account for approximately 41% of the global total land area. Significant warming and rare precipitation in drylands result in a fragile ecology and deterioration of the living environment, making it more sensitive to global climate change. As an important regulator of the Earth's climate system, the oceans play a vital role in the process of climate change in drylands. In modern climate change in particular, the impact of marine activities on climate change in drylands cannot be neglected. This paper reviews the characteristics of climate change in drylands over the past 100 years, and summarizes the researches conducted on the impact of marine activities on these changes. The review focuses on the impact of the Pacific Decadal Oscillation(PDO), Atlantic Multidecadal Oscillation(AMO), El Ni?o and La Ni?a on climate change in drylands, and introduces the mechanisms by which different oceanic oscillation factors synergistically affect climate change in drylands.Studies have shown that global drylands have experienced a significant intensification in warming in the past 100 years, which shows obvious characteristics of interdecadal dry/wet variations. The characteristics of these changes are closely related to the oscillatory factors of the oceanic interdecadal scale. Different phase combinations of oceanic oscillation factors significantly change the land-sea thermal contrast, which in turn affects the westerly jet, planetary wave and blocking frequency, resulting in changes in the temperature and dry/wet characteristics of drylands. With the intensification of climate change in drylands, the impact of marine activities on these regions will reveal new characteristics in the future, which will increase the uncertainty of future climate change in drylands and intensify the impact of these drylands on global climate. | Xiaodan GUAN Jieru MA Jianping HUANG Ruixin HUANG Lei ZHANG Zhuguo MA | 2019 | Science China Earth Sciences2019，62，6： | 5 |
| 6 | SSR genetic linkage map construction of pea(Pisum sativum L.) based on Chinese native varieties显示文摘Simple sequence repeat(SSR)markers have previously been applied to linkage mapping of the pea(Pisum sativum L.)genome.However,the transferability of existing loci to the molecularly distinct Chinese winter pea gene pool was limited.A novel set of pea SSR markers was accordingly developed.Together with existing SSR sequences,the genome of the G0003973(winter hardy)×G0005527(cold sensitive)cross was mapped using 190 F2individuals.In total,157 SSR markers were placed in 11 linkage groups with an average interval of 9.7 cM and total coverage of 1518 cM.The novel markers and genetic linkage map will be useful for marker-assisted pea breeding. | Xuelian Sun Tao Yang Junjie Hao Xiaoyan Zhang Rebecca Ford Junye Jiang Fang Wang Jianping Guan Xuxiao Zong | 2014 | The Crop Journal2014，2，Z1： | 4 |
| 7 | Searching for the Nano-Hertz Stochastic Gravitational Wave Background with the Chinese Pulsar Timing Array Data ReleaseⅠ显示文摘Observing and timing a group of millisecond pulsars with high rotational stability enables the direct detection of gravitational waves(GWs).The GW signals can be identified from the spatial correlations encoded in the times-of-arrival of widely spaced pulsar-pairs.The Chinese Pulsar Timing Array(CPTA)is a collaboration aiming at the direct GW detection with observations carried out using Chinese radio telescopes.This short article serves as a“table of contents”for a forthcoming series of papers related to the CPTA Data Release 1(CPTA DR1)which uses observations from the Five-hundred-meter Aperture Spherical radio Telescope.Here,after summarizing the time span and accuracy of CPTA DR1,we report the key results of our statistical inference finding a correlated signal with amplitude logA_(c)=-14.4_(-2.8)^(+1.0)for spectral index in the range ofα∈[-1.8,1.5]assuming a GW background(GWB)induced quadrupolar correlation.The search for the Hellings–Downs(HD)correlation curve is also presented,where some evidence for the HD correlation has been found that a 4.6σstatistical significance is achieved using the discrete frequency method around the frequency of 14 n Hz.We expect that the future International Pulsar Timing Array data analysis and the next CPTA data release will be more sensitive to the n Hz GWB,which could verify the current results. | Heng Xu Siyuan Chen Yanjun Guo Jinchen Jiang Bojun Wang Jiangwei Xu Zihan Xue RNicolas Caballero Jianping Yuan Yonghua Xu Jingbo Wang Longfei Hao Jingtao Luo Kejia Lee Jinlin Han Peng Jiang Zhiqiang Shen Min Wang Na Wang Renxin Xu Xiangping Wu Richard Manchester Lei Qian Xin Guan Menglin Huang Chun Sun Yan Zhu | 2023 | Research in Astronomy and Astrophysics2023，23，7： | 3 |
| 8 | Desulphurization during VIM Refining Ni-base Superalloy using CaO Crucible显示文摘The variation of S content during VIM refining Ni-base superalloy using CaO crucible was stud[ed. It was foundthat the desulphurization process could not be carried out by only using CaO crucible. The role of Al additionto desulphurization was also studied. Combining with the results of XRD and composition analysis of the CaOcrucible, the mechanism of desulphurization was proposed. Thermodynamical calculation about the reaction betweenthe interface of CaO crucible and liquid metal has been discussed. This work indicated that under proper refiningtechnology the S content in the liquid Ni-base alloy could be reduced from 3×10-5 to 2×10-6~4×10-6. | Jianping NIU, Kenu YANG, Tao JIN, Xiaofeng SUN, Hengrong GUAN and Zhuangqi HUInstitute of Metal Research, Chinese Academy of Sciences, Shenyang 110016, China | 2003 | Journal of Materials Science & Technology2003，19，1： | 3 |
| 9 | The Langmuir Probe onboard CSES: data inversion analysis method and first results显示文摘The Langmuir Probe(LAP), onboard the China Seismo-Electromagnetic Satellite(CSES), has been designed for in situ measurements of bulk parameters of the ionosphere plasma, the first Chinese application of in-situ measurement technology in the field of space exploration. The two main parameters measured by LAP are electron density and temperature. In this paper, a brief description of the LAP and its work mode are provided. Based on characteristics of the LAP, and assuming an ideal plasma environment, we introduce in detail a method used to invert the I-V curve; the data products that can be accessed by users are shown. Based on the LAP data available, this paper reports that events such as earthquakes and magnetic storms are preceded and followed by obvious abnormal changes. We suggest that LAP could provide a valuable data set for studies of space weather, seismic events, and the ionospheric environment. | Rui Yan YiBing Guan XuHui Shen JianPing Huang XueMin Zhang Chao Liu DaPeng Liu | 2018 | Earth and Planetary Physics2018，2，6： | 2 |
| 10 | Balancing selection and wild gene pool contribute to resistance in global rice germplasm against planthopper显示文摘Interactions and co-evolution between plants and herbivorous insects are critically important in agriculture.Brown planthopper(BPH)is the most severe insect of rice,and the biotypes adapt to feed on different rice genotypes.Here,we present genomics analyses on 1,520 global rice germplasms for resistance to three BPH biotypes.Genome-wide association studies identified 3,502 single nucleotide polymorphisms(SNPs)and 59 loci associated with BPH resistance in rice.We cloned a previously unidentified gene Bph37 that confers resistance to BPH.The associated loci showed high nucleotide diversity.Genome-wide scans for trans-species polymorphisms revealed ancient balancing selection at the loci.The secondarily evolved insect biotypes II and III exhibited significantly higher virulence and overcame more rice varieties than the primary biotype I.In response,more SNPs and loci evolved in rice for resistance to biotypes II and III.Notably,three exceptional large regions with high SNP density and resistance-associated loci on chromosomes 4 and 6 appear distinct between the resistant and susceptible rice varieties.Surprisingly,these regions in resistant rice might have been retained from wild species Oryza nivara.Our findings expand the understanding of long-term interactions between rice and BPH and provide resistance genes and germplasm resources for breeding durable BPH-resistant rice varieties. | Cong Zhou Qian Zhang Yu Chen Jin Huang Qin Guo Yi Li Wensheng Wang Yongfu Qiu Wei Guan Jing Zhang Jianping Guo Shaojie Shi Di Wu Xiaohong Zheng Lingyun Nie Jiaoyan Tan Chaomei Huang Yinhua Ma Fang Yang Xiqin Fu Bo Du Lili Zhu Rongzhi Chen Zhikang Li Longping Yuan Guangcun He | 2021 | Journal of Integrative Plant Biology2021，63，10： | 2 |

| 12 | Mitochondrial protein IF1 is a potential regulator of glucagon-like peptide(GLP-1) secretion function of the mouse intestine显示文摘IF1(ATPIF1) is a nuclear DNA-encoded mitochondrial protein whose activity is inhibition of the F1Fo-ATP synthase to control ATP production.IF1 activity remains unknown in the regulation of GLP-1 activity.In this study,IF1 was examined in the diet-induced obese mice using the gene knockout(If1-KO) mice.The mice gained more body weight on a high fat diet without a change in food intake.Insulin tolerance was impaired,but the oral glucose tolerance was improved through an increase in GLP-1 secretion.The KO mice exhibited an improved intestine structure,mitochondrial superstructure,enhanced mitophagy,reduced apoptosis and decreased adenine nucleotide translocase 2(ANT2) protein in the intestinal epithelial cells together with preserved gut microbiota.The data suggest that GLP-1 secretion was enhanced in the obese If1-KO mice to preserve glucose tolerance through a signaling pathway of ANT2/mitochondria/L-cells/GLP-1/insulin.IF1 is a potential mitochondrial target for induction of GLP-1 secretion in L-cells. | Ying Wang Jiaojiao Zhang Xinyu Cao Yaya Guan Shuang Shen Genshen Zhong Xiwen Xiong Yanhong Xu Xiaoying Zhang Hui Wang Jianping Ye | 2021 | Acta Pharmaceutica Sinica B2021，11，6： | 1 |

| 17 | Lipidomic analyses reveal enhanced lipolysis in planthoppers feeding on resistant host plants显示文摘The brown planthopper(BPH)(Nilaparvata lugens St?l)is a highly destructive pest that seriously damages rice(Oryza sativa L.)and causes severe yield losses.To better understand the physiological and metabolic mechanisms through which BPHs respond to resistant rice,we combined mass-spectrometry-based lipidomics with transcriptomic analysis and gene knockdown techniques to compare the lipidomes of BPHs feeding on either of the two resistant(NIL-Bph6 and NIL-Bph9)plants or a wild-type,BPH susceptible(9311)plant.Insects that were fed on resistant rice transformed triglyceride(TG)to phosphatidylcholine(PC)and digalactosyldiacylglycerol(DGDG),with these lipid classes showing significant alterations in fatty acid composition.Moreover,the insects that were fed on resistant rice were characterized by prominent expression changes in genes involved in lipid metabolism processes.Knockdown of the NlBmm gene,which encodes a lipase that regulates the mobilization of lipid reserves,significantly increased TG content and feeding performance of BPHs on resistant plants relative to dsGFP-injected BPHs.Our study provides the first detailed description of lipid changes in BPHs fed on resistant and susceptible rice genotypes.Results from BPHs fed on resistant rice plants reveal that these insects can accelerate TG mobilization to provide energy for cell proliferation,body maintenance,growth and oviposition. | Xiaohong Zheng Yeyun Xin Yaxin Peng Junhan Shan Ning Zhang Di Wu Jianping Guo Jin Huang Wei Guan Shaojie Shi Cong Zhou Rongzhi Chen Bo Du Lili Zhu Fang Yang Xiqin Fu Longping Yuan Guangcun He | 2021 | Science China(Life Sciences)2021，64，9： | 1 |
| 18 | Polarimetric parity-time symmetry in a photonic system显示文摘Parity-time(PT)symmetry has attracted intensive research interest in recent years.PT symmetry is conventionally implemented between two spatially distributed subspaces with identical localized eigenfrequencies and complementary gain and loss coefficients.The implementation is complicated.In this paper,we propose and demonstrate that PT symmetry can be implemented between two subspaces in a single spatial unit based on optical polarimetric diversity.By controlling the polarization states of light in the single spatial unit,the localized eigenfrequencies,gain,loss,and coupling coefficients of two polarimetric loops can be tuned,leading to PT symmetry breaking.As a demonstration,a fiber ring laser based on this concept supporting stable and single-mode lasing without using an ultranarrow bandpass filter is implemented. | Lingzhi Li Yuan Cao Yanyan Zhi Jiejun Zhang Yuting Zou Xinhuan Feng Bai-Ou Guan Jianping Yao | 2020 | Light(Science & Applications)2020，9，1： | 1 |
| 19 | Cryptosporidiosis threat under climate change in China:prediction and validation of habitat suitability and outbreak risk for human-derived Cryptosporidium based on ecological niche models显示文摘Background Cryptosporidiosis is a zoonotic intestinal infectious disease caused by Cryptosporidium spp.,and its transmission is highly influenced by climate factors.In the present study,the potential spatial distribution of Cryptosporidium in China was predicted based on ecological niche models for cryptosporidiosis epidemic risk warning and prevention and control.Methods The applicability of existing Cryptosporidium presence points in ENM analysis was investigated based on data from monitoring sites in 2011–2019.Cryptosporidium occurrence data for China and neighboring countries were extracted and used to construct the ENMs,namely Maxent,Bioclim,Domain,and Garp.Models were evaluated based on Receiver Operating Characteristic curve,Kappa,and True Skill Statistic coefficients.The best model was constructed using Cryptosporidium data and climate variables during 1986‒2010,and used to analyze the effects of climate factors on Cryptosporidium distribution.The climate variables for the period 2011‒2100 were projected to the simulation results to predict the ecological adaptability and potential distribution of Cryptosporidium in future in China.Results The Maxent model(AUC=0.95,maximum Kappa=0.91,maximum TSS=1.00)fit better than the other three models and was thus considered the best ENM for predicting Cryptosporidium habitat suitability.The major suitable habitats for human-derived Cryptosporidium in China were located in some high-population density areas,especially in the middle and lower reaches of the Yangtze River,the lower reaches of the Yellow River,and the Huai and the Pearl River Basins(cloglog value of habitat suitability>0.9).Under future climate change,non-suitable habitats for Cryptosporidium will shrink,while highly suitable habitats will expand significantly(χ^(2)=76.641,P<0.01;χ^(2)=86.836,P<0.01),and the main changes will likely be concentrated in the northeastern,southwestern,and northwestern regions.Conclusions The Maxent model is applicable in prediction of Cryptosporidium habitat suitability and can achieve excellent simulation results.These results suggest a current high risk of transmission and significant pressure for cryptosporidiosis prevention and control in China.Against a future climate change background,Cryptosporidium may gain more suitable habitats within China.Constructing a national surveillance network could facilitate further elucidation of the epidemiological trends and transmission patterns of cryptosporidiosis,and mitigate the associated epidemic and outbreak risks. | Xu Wang Yanyan Jiang Weiping Wu Xiaozhou He Zhenghuan Wang Yayi Guan Ning Xu Qilu Chen Yujuan Shen Jianping Cao | 2023 | Infectious Diseases of Poverty2023，12，2： | 0 |
| 20 | Insights into Pyrolysis of Nano-Polystyrene Particles: Thermochemical Behaviors and Kinetics Analysis显示文摘The thermal degradation kinetics of nano-polystyrene particles with diameters of 60,90,160,and 225 nm were investigated in nitrogen atmosphere using thermogravimetric analysis(TGA).Various kinetic models were employed to determine the thermal degradation mechanism and kinetics.Nano-polystyrene particles have relatively lower thermal stability when compared to micro-polystyrene.Both differential thermo–gravimetric(DTG)data and apparent activation energies indicate that the thermal degradation of nano-polystyrene particles at 60 nm is a two-step reaction process where the second step plays a dominant role,while nano-polystyrene particles with diameter greater than 60 nm exhibit single-step degradation.Similar to most micro/macro polystyrene particles,DTG peaks of nano-polystyrene particles shift towards higher temperatures with increasing heating rates.Thermal degradation of nano-polystyrene particles under nitrogen atmosphere follows the first-order reaction model.However,the apparent activation energies increase(162-181 kJ·mol–1)with the increase of particle sizes(60-225 nm).This study could provide some insights into pyrolysis of nano-polystyrene particles and a safer process of manufacturing,storage and handling of nano-polystyrene particles. | DING Li ZHAO Jianping PAN Yong GUAN Jin JIANG Juncheng WANG Qingsheng | 2019 | Journal of Thermal Science2019，28，4： | 0 |
