3Predicting the onset temperature(Tg) of GexSe1-x glass transition: a feature selection based two-stage support vector regression method显示文摘Despite the usage of both experimental and topological methods, realizing a rapid and accurate measurement of the onset temperature(Tg ) of GexSe1-xglass transition remains an open challenge. In this paper, a predictive model for the Tg in GexSe1-xglass system is presented by a machine learning method named feature selection based two-stage support vector regression(FSTS-SVR). Firstly, Pearson correlation coefficient(PCC) is used to select features highly correlated with Tg from the candidate features of GexSe1-x glass system. Secondly, in order to simulate the two-stage characteristic of Tg which is caused by structural variation with a turning point at x = 0.33 via the structural analysis, SVR is utilized to build predictive models for two stages separately and then the two achieved models are synthesized using a minimum error based model for Tg prediction. Compared with the topological and other methods based on SVR, the FSTS-SVR gives the highest predictive accuracy with the root mean square error(RMSE) and mean absolute percentage error(MAPE) of 10.64 K and 2.38%, respectively. This method is also expected to be more efficient for the prediction of Tg of other glass systems with the multi-stage characteristic.Yue Liu Junming Wu Guang Yang Tianlu Zhao Siqi Shi 2019Science Bulletin2019,64,16:12
4Wheat genomic study for genetic improvement of traits in China显示文摘Bread wheat(Triticum aestivum L.)is a major crop that feeds 40%of the world’s population.Over the past several decades,advances in genomics have led to tremendous achievements in understanding the origin and domestication of wheat,and the genetic basis of agronomically important traits,which promote the breeding of elite varieties.In this review,we focus on progress that has been made in genomic research and genetic improvement of traits such as grain yield,end-use traits,flowering regulation,nutrient use efficiency,and biotic and abiotic stress responses,and various breeding strategies that contributed mainly by Chinese scientists.Functional genomic research in wheat is entering a new era with the availability of multiple reference wheat genome assemblies and the development of cutting-edge technologies such as precise genome editing tools,highthroughput phenotyping platforms,sequencing-based cloning strategies,high-efficiency genetic transformation systems,and speed-breeding facilities.These insights will further extend our understanding of the molecular mechanisms and regulatory networks underlying agronomic traits and facilitate the breeding process,ultimately contributing to more sustainable agriculture in China and throughout the world.Jun Xiao Bao Liu Yingyin Yao Zifeng Guo Haiyan Jia Lingrang Kong Aimin Zhang Wujun Ma Zhongfu Ni Shengbao Xu Fei Lu Yuannian Jiao Wuyun Yang Xuelei Lin Silong Sun Zefu Lu Lifeng Gao Guangyao Zhao Shuanghe Cao Qian Chen Kunpu Zhang Mengcheng Wang Meng Wang Zhaorong Hu Weilong Guo Guoqiang Li Xin Ma Junming Li Fangpu Han Xiangdong Fu Zhengqiang Ma Daowen Wang Xueyong Zhang Hong-Qing Ling Guangmin Xia Yiping Tong Zhiyong Liu Zhonghu He Jizeng Jia Kang Chong 2022Science China(Life Sciences)2022,65,9:9
5White Matter Abnormalities in Major Depression Biotypes Identified by Diffusion Tensor Imaging显示文摘Identifying data-driven biotypes of major depressive disorder(MDD) has promise for the clarification of diagnostic heterogeneity. However, few studies have focused on white-matter abnormalities for MDD subtyping. This study included 116 patients with MDD and118 demographically-matched healthy controls assessed by diffusion tensor imaging and neurocognitive evaluation.Hierarchical clustering was applied to the major fiber tracts, in conjunction with tract-based spatial statistics, to reveal white-matter alterations associated with MDD.Clinical and neurocognitive differences were compared between identified subgroups and healthy controls. With fractional anisotropy extracted from 20 fiber tracts, cluster analysis revealed 3 subgroups based on the patterns of abnormalities. Patients in each subgroup versus healthy controls showed a stepwise pattern of white-matter alterations as follows: subgroup 1(25.9% of patient sample),widespread white-matter disruption;subgroup 2(43.1% of patient sample), intermediate and more localized abnormalities in aspects of the corpus callosum and left cingulate;and subgroup 3(31.0% of patient sample),possible mild alterations, but no statistically significant tract disruption after controlling for family-wise error. The neurocognitive impairment in each subgroup accompanied the white-matter alterations: subgroup 1, deficits in sustained attention and delayed memory;subgroup 2, dysfunction in delayed memory;and subgroup 3, no significant deficits. Three subtypes of white-matter abnormality exist in individuals with major depression, those having widespread abnormalities suffering more neurocognitive impairments, which may provide evidence for parsing the heterogeneity of the disorder and help optimize typespecific treatment approaches.Sugai Liang Qiang Wang Xiangzhen Kong Wei Deng Xiao Yang Xiaojing Li Zhong Zhang Jian Zhang Chengcheng Zhang Xin-min Li Xiaohong Ma Junming Shao Andrew J.

6Cambrian integrative stratigraphy and timescale of China显示文摘The Cambrian Period is the first period of the Phanerozoic Eon and witnessed the explosive appearance of the metazoans, representing the beginning of the modern earth-life system characterized by animals in contrary to the Precambrian earth-life system dominated by microbial life. However, understanding Cambrian earth-life system evolution is hampered by regional and global stratigraphic correlations due to an incomplete chronostratigraphy and consequent absence of a highresolution timescale. Here we briefly review the historical narrative of the present international chronostratigraphic framework of the Cambrian System and summarize recent advances and problems of the undefined Cambrian stage GSSPs, in particular we challenge the global correlation of the GSSP for the Cambrian base, in addition to Cambrian chemostratigraphy and geochronology. Based on the recent advances of the international Cambrian chronostratigraphy, revisions to the Cambrian chronostratigraphy of China, which are largely based on the stratigraphic record of South China, are suggested, and the Xiaotanian Stage is newly proposed for the Cambrian Stage 2 of China. We further summarize the integrative stratigraphy of South China, North China and Tarim platforms respectively with an emphasis on the facies variations of the Precambrian-Cambrian boundary successions and problems for identification of the Cambrian base in the different facies and areas of China. Moreover, we discuss stratigraphic complications that are introduced by poorly fossiliferous dolomite successions in the upper Cambrian System which are widespread in South China, North China and Tarim platforms.Maoyan ZHU Aihua YANG Jinliang YUAN Guoxiang LI Junming ZHANG Fangchen ZHAO Soo-Yeun AHN Lanyun MIAO 2019Science China Earth Sciences2019,62,1:8
7Early Cambrian eodiscoid trilobites of the Yangtze Platform and their stratigraphic implications显示文摘Analysis of the taxonomy and stratigraphic distribution of the Early Cambrian eodiscoid trilobites of the Yangtze Platform indicates that species of Tsunyidiscus and Hupeidiscus can be used for biostratigraphic correlation. T. aclis occurs only in the lower Qiongzhusian, T. armatus occurs in the lower and middle Qiongzhusian, while T. niutitangensis and T. tingi occur mainly in the middle and upper Qiongzhusian, with only T. tingi extending upward into the lower Canglangpuian. H. orientalis first appears in the upper Qiongzhusian, reaching peak abundance in the lower Canglangpuian and becoming extinct above the Drepanuroides Zone. Biostratigraphic and lithostratigraphic correlations indicate that the limestone in the lower part of the Mingxinsi Formation, the Upper Member of Jiumenchong Formation, and the upper part of the Middle Member of the Huangbailing Formation, can be correlated with each other as Hupediscus, an index fossil of the lower Canglangpuian, is abundant in all these units. The lower part of the Niutitang and Jiumenchong formations in eastern Guizhou, which mainly represent Qiongzhusian strata, can be correlated with the Lower Member of the Huangbailing Formation. The basal part of the Niutitang Formation, which may be equivalent to the Upper Meishucunian Shiyantou Formation in eastern Yunnan, is very condensed. Well-preserved sponge faunas and non-mineralized fossils in the lower part of the Niutitang and Hetang formations are not older than Qiongzhusian in age.YANG Aihua, ZHU Maoyan*, ZHANG Junming and LI Guoxiang(Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences, Nanjing 210008, China) 2003Progress in Natural Science:Materials International2003,13,11:7
8Design of hierarchical, three-dimensional free-standing single-atom electrode for H2O2 production in acidic media显示文摘Electrochemical reduction of molecular O2 to hydrogen peroxide(H2O2)offers a promising solution for water purification and environmental remediation.Here,we design a hierarchical free-standing single-Co-atom(with Co-N4 coordination)electrode for oxygen reduction reaction(ORR)via a two-electron pathway to make H2O2 in acidic media.The current density of the single-Co-atom electrode reached 51 mA/cm2 at 0.1 V vs reversible hydrogen electrode,lasting for more than 10 hours of continuous operation with H2O2 selectivity greater than 80%.Toward practical application,the single-Co-atom electrode was directly used to assemble an electrochemical cell to produce H2O2 at a rate of 676 mol/kgcat/h with a cell voltage of about 1.6 V.Jincheng Zhang Hongbin Yang Jiajian Gao Shibo Xi Weizheng Cai Junming Zhang Ping Cui Bin Liu 2020Carbon Energy2020,2,2:6
9Targeted Fully Homomorphic Encryption Based on a Double Decryption Algorithm for Polynomials显示文摘Several public-key encryption schemes used to solve the problem of ciphertext data processing on the fly are discussed.A new targeted fully homomorphic encryption scheme based on the discrete logarithm problem is presented.Public-key encryption cryptosystems are classified to examine homomorphic encryption.Without employing techniques proposed by Gentry such as somewhat homomorphic and bootstrapping techniques,or relinearization technique proposed by Brakerski et al.,a new method called'Double Decryption Algorithm'is employed in our cryptography to satisfy a fully or targeted fully homomorphic property.Inspired by ElGamal and BGN cryptography,we obtain the desired fully homomorphic property by selecting a new group and adding an extra component to the ciphertext.Proof of semantic security is also demonstrated.Yatao Yang Shuang Zhang Junming Yang Jia Li Zichen Li 2014Tsinghua Science and Technology2014,19,5:6
10Combined deficiency of SLAMF8 and SLAMF9 prevents endotoxin-induced liver inflammation by downregulating TLR4 expression on macrophages显示文摘Classical signaling lymphocyte activating molecule(SLAM)family receptors are abundant within many types of immune cells,whereas the nonclassical SLAM family receptors SLAMF8 and SLAMF9,which uniquely lack cytoplasmic signaling motifs,are highly expressed by myeloid cells.Due to the potential redundancy,whether these two receptors regulate macrophage function remains largely unknown.Here,we show that SLAMF8 and SLAMF9 co-regulate macrophage-mediated liver inflammation.To overcome the redundancy,we generated mice that simultaneously lacked SLAMF8 and SLAMF9 using CRISPR-Cas9 technology.Although macrophage differentiation was not altered by the combined deficiency of SLAMF8 and SLAMF9,the loss of these two receptors significantly protected against lipopolysaccharide(LPS)-induced liver injury.SLAMF8 and SLAMF9 double-deficient mice had a prolonged survival rate and less infiltration of inflammatory cells.The depletion of macrophages using clodronate liposomes abolished the effects of SLAMF8 and SLAMF9 deficiencies on LPS-induced liver injury,which demonstrates that these receptors are required for macrophage activation following LPS challenge.Moreover,the deficiency of SLAMF8 and SLAMF9 suppressed the secretion of inflammatory cytokines by downregulating the expression of Toll-like receptor-4(TLR4),a receptor that specifically binds LPS,which led to decreased mitogen-activated protein kinases(MAPK)signaling activation.Notably,combined injections of truncated extracellular SLAMF8 and SLAMF9 proteins significantly alleviated LPS-induced liver injury.Thus,our findings provide insights into the role of SLAMF8 and SLAMF9 in endotoxin-induced liver injury and suggest that SLAMF8 and SLAMF9 are potential therapeutic targets for acute hepatic injury.Xiaokang Zeng Guangao Liu Wanwen Peng Junming He Chenxu Cai Wei Xiong Shasha Chen Meixiang Yang Zhongjun Dong 2020Cellular & Molecular Immunology2020,17,2:5
11A new strain of Crimean-Congo hemorrhagic fever virus isolated from Xinjiang, China显示文摘Crimean-Congo hemorrhagic fever virus(CCHFV) is a highly pathogenic tick-borne virus with a fatality rate of up to 50% in humans. CCHFV is widely distributed in countries around the world.Outbreaks of CCHFV infection in humans have occurred in prior years in Xinjiang Province, China.Epidemiological surveys have detected CCHFV RNA in ticks and animals; however, few isolates were identified. In this study, we identified and isolated a new CCHFV strain from Hyalomma asiaticum asiaticum ticks collected from north of Tarim Basin in Xinjiang, China. A preliminary investigation of infection and antigens expression of CCHFV was performed in newborn mice. The target tissues for CCHFV replication in newborn mice were identified. The analysis of the phylogenetic relationships with other Chinese strains suggested that diverse genotypes of CCHFV have circulated in Xinjiang for years. These findings provide important insights into our understanding of CCHFV infection and evolution as well as disease prevention and control for local residents.Rong Guo Shu Shen Yanfang Zhang Junming Shi Zhengyuan Su Dan Liu Jinliang Liu Juan Yang Qiguo Wang Zhihong Hu Yujiang Zhang Fei Deng 2017Virologica Sinica2017,32,1:5
12Light-absorbing impurities on Keqikaer Glacier in western Tien Shan: concentrations and potential impact on albedo reduction显示文摘Light-absorbing impurities on glaciers are important factors that influence glacial surface albedo and accelerate glacier melt. In this study, the quantity of light-absorbing impurities on Keqikaer Glacier in western Tien Shan, Central Asia, was measured. We found that the average concentrations of black carbon was 2,180 ng/g, with a range from 250 ng/g to more than 10,000 ng/g. The average concentrations of organic carbon and mineral dust were 1,738 ng/g and 194 μg/g, respectively. Based on simulations performed with the Snow Ice Aerosol Radiative model simulations, black carbon and dust are responsible for approximately 64% and 9%, respectively, of the albedo reduction, and are associated with instantaneous radiative forcing of 323.18 W/m2(ranging from 142.16 to 619.25 W/m2) and 24.05 W/m2(ranging from 0.15 to69.77 W/m2), respectively. For different scenarios, the albedo and radiative forcing effect of black carbon is considerably greater than that of dust. The estimated radiative forcing at Keqikaer Glacier is higher than most similar values estimated by previous studies on the Tibetan Plateau, perhaps as a result of black carbon enrichment by melt scavenging. Light-absorbing impurities deposited on Keqikaer Glacier appear to mainly originate from central Asia, Siberia, western China(including the Taklimakan Desert) and parts of South Asia in summer, and from the Middle East and Central Asia in winter.A footprint analysis indicates that a large fraction(>60%) of the black carbon contributions on Keqikaer Glacier comes from anthropogenic sources. These results provide a scientific basis for regional mitigation efforts to reduce black carbon.YuLan Zhang ShiChang Kang Min Xu Michael Sprenger TanGuang Gao ZhiYuan Cong ChaoLiu Li JunMing Guo ZhiQiang Xu Yang Li Gang Li XiaoFei Li YaJun Liu HaiDong Han 2017Research in Cold and Arid Regions2017,9,2:4
13The Tibetan Plateau Surface–Atmosphere Coupling System and Its Weather and Climate Effects: The Third Tibetan Plateau Atmospheric Science Experiment显示文摘The Tibetan Plateau(TP) is a key area affecting forecasts of weather and climate in China and occurrences of extreme weather and climate events over the world. The China Meteorological Administration, the National Natural Science Foundation of China, and the Chinese Academy of Sciences jointly initiated the Third Tibetan Plateau Atmospheric Science Experiment(TIPEX-Ⅲ) in 2013, with an 8–10-yr implementation plan. Since its preliminary field measurements conducted in 2013, routine automatic sounding systems have been deployed at Shiquanhe, Gaize, and Shenzha stations in western TP, where no routine sounding observations were available previously. The observational networks for soil temperature and soil moisture in the central and western TP have also been established. Meanwhile, the plateau-scale and regional-scale boundary layer observations, cloud–precipitation microphysical observations with multiple radars and aircraft campaigns, and tropospheric–stratospheric air composition observations at multiple sites, were performed. The results so far show that the turbulent heat exchange coefficient and sensible heat flux are remarkably lower than the earlier estimations at grassland, meadow, and bare soil surfaces of the central and western TP. Climatologically, cumulus clouds over the main body of the TP might develop locally instead of originating from the cumulus clouds that propagate northward from South Asia. The TIPEX-Ⅲ observations up to now also reveal diurnal variations, macro-and microphysical characteristics, and water-phase transition mechanisms, of cumulus clouds at Naqu station. Moreover, TIPEX-Ⅲ related studies have proposed a maintenance mechanism responsible for the Asian 'atmospheric water tower' and demonstrated the effects of the TP heating anomalies on African, Asian, and North American climates. Additionally, numerical modeling studies show that the Γ distribution of raindrop size is more suitable for depicting the TP raindrop characteristics compared to the M–P distribution, the overestimation of sensible heat flux can be reduced via modifying the heat transfer parameterization over the TP, and considering climatic signals in some key areas of the TP can improve the skill for rainfall forecast in the central and eastern parts of China. Furthermore, the TIPEX-Ⅲ has been promoting the technology in processing surface observations, soundings, and radar observations, improving the quality of satellite retrieved soil moisture and atmospheric water vapor content products as well as high-resolution gauge–radar–satellite merged rainfall products, and facilitating the meteorological monitoring, forecasting, and data sharing operations.Ping ZHAO Yueqing LI Xueliang GUO Xiangde XU Yimin LIU Shihao TANG Wenming XIAO Chunxiang SHI Yaoming MA Xing YU Huizhi LIU La JIA Yun CHEN Yanju LIU Jian LI Dabiao LUO Yunchang CAO Xiangdong ZHENG Junming CHEN An XIAO Fang YUAN Donghui CHEN Yang PANG Zhiqun HU Shengjun ZHANG Lixin DONG Juyang HU Shuai HAN Xiuji ZHOU 2019Journal of Meteorological Research2019,33,3:4

15Enhanced damping capacity of ferromagnetic Fe-Ga alloys by introducing structural defects显示文摘The irreversible motion of magnetic domain walls in ferromagnets can dissipate a large portion of the elastic energy,and the associated damping capacity is proportional to the magnetostriction constant.In contrast,here we found that the damping capacity of the large magnetostriction Fe-Ga alloys can be enhanced by 2-3 times through introducing structural defects including interfacial dislocations and stacking faults,despite that these defects deteriorate the magnetostriction.These structural defects were introduced by aging the BCC(body-centered-cubic)solution-treated precursor,for which the formation of mechanically harder FCT(face-centered-tetragonal)and/or FCC(face-centered-cubic)phases can result in high-density partial dislocations at the semi-coherent phase interfaces and quasi-periodically stacked nano-layer substructure inside the FCC variants.The structural defects act as extra damping sources besides the magnetic domain walls because the structural accommodation of the semi-coherent phase interfaces between BCC and FCT/FCC nanoprecipitates with different elastic moduli and the nano-layer substructure towards long-range ordered periodical stacking can dissipate a large portion of mechanical energy.These findings suggest that introducing structural defects provides fresh freedom to design high damping ferromagnetic materials.Ruihua Qiao Junming Gou Tianzi Yang Yiqun Zhang Feng Liu Shanshan Hu Tianyu Ma 2021Journal of Materials Science & Technology2021,,25:3
16A putative bHLH transcription factor is a candidate gene for male sterile 32,a locus affecting pollen and tapetum development in tomato显示文摘The tomato(Solanum lycopersicum)male sterile 32(ms32)mutant has been used in hybrid seed breeding programs largely because it produces no pollen and has exserted stigmas.In this study,histological examination of anthers revealed dysfunctional pollen and tapetum development in the ms32 mutant.The ms32 locus was fine mapped to a 28.5 kb interval that encoded four putative genes.Solyc01g081100,a homolog of Arabidopsis bHLH10/89/90 and rice EAT1,was proposed to be the candidate gene of MS32 because it contained a single nucleotide polymorphism(SNP)that led to the formation of a premature stop codon.A codominant derived cleaved amplified polymorphic sequence(dCAPS)marker,MS32D,was developed based on the SNP.Real-time quantitative reverse-transcription PCR showed that most of the genes,which were proposed to be involved in pollen and tapetum development in tomato,were downregulated in the ms32 mutant.These findings may aid in marker-assisted selection of ms32 in hybrid breeding programs and facilitate studies on the regulatory mechanisms of pollen and tapetum development in tomato.Xiaoyan Liu Mengxia Yang Xiaolin Liu Kai Wei Xue Cao Xiaotian Wang Xiaoxuan Wang Yanmei Guo Yongchen Du Junming Li Lei Liu Jinshuai Shu Yong Qin Zejun Huang 2019Horticulture Research2019,6,1:3
17Joint channel assignment and cross-layer routing protocol for multi-radio multi-channel Ad Hoc networks显示文摘To study multi-radio multi-channel (MR-MC) Ad Hoc networks based on 802.11, an efficient cross-layer routing protocol with the function of joint channel assignment, called joint channel assignment and cross-layer routing (JCACR), is presented. Firstly, this paper introduces a new concept called channel utilization percentage (CUP), which is for measuring the contention level of different channels in a node’s neighborhood, and deduces its optimal value for determining whether a channel is overloaded or not. Then, a metric parameter named channel selection metric (CSM) is designed, which actually reffects not only the channel status but also corresponding node’s capacity to seize it. JCACR evaluates channel assignment by CSM, performs a local optimization by assigning each node a channel with the smaller CSM value, and changes the working channel dynamically when the channel is overloaded. Therefore, the network load balancing can be achieved. In addition, simulation shows that, when compared with the protocol of weighted cumulative expected transfer time (WCETT), the new protocol can improve the network throughput and reduce the end-to-end average delay with fewer overheads.Yang Lu Junming Guan Zhen Wei Qilin Wu 2010Journal of Systems Engineering and Electronics2010,21,6:2
18A BRD4 PROTAC nanodrug for glioma therapy via the intervention of tumor cells proliferation,apoptosis and M2 macrophages polarization显示文摘Glioma is a primary aggressive brain tumor with high recurrence rate.The poor efficiency of chemotherapeutic drugs crossing the blood-brain barrier(BBB) is well-known as one of the main challenges for anti-glioma therapy.Moreover,massive infiltrated tumor-associated macrophages(TAMs) in glioma further thwart the drug efficacy.Herein,a therapeutic nanosystem(SPP-ARV-825) is constructed by incorporating the BRD4-degrading proteolytic targeting chimera(PROTAC) ARV-825 into the complex micelle(SPP) composed of substance P(SP) peptide-modified poly(ethylene glycol)-poly(D,L-lactic acid)(SP-PEG-PDLL A) and methoxy poly(ethylene glycol)-poly(D,L-lac tic acid)(mPEG-PDLL A,PP),which could penetrate BBB and target brain tumor.Subsequently,released drug engenders antitumor effect via attenuating cells proliferation,inducing cells apoptosis and suppressing M2 macrophages polarization through the inhibition of IRF4 promoter transcription and phosphorylation of STAT6,STAT3 and AKT.Taken together,our work demonstrates the versatile role and therapeutic efficacy of SPP-ARV-825 micelle against glioma,which may provide a novel strategy for glioma therapy in future.Tingting Yang Yuzhu Hu Junming Miao Jing Chen Jiagang Liu Yongzhong Cheng Xiang Gao 2022Acta Pharmaceutica Sinica B2022,12,6:2
19Biological roles and potential clinical values of circular RNAs in gastrointestinal malignancies显示文摘Circular RNAs(circ RNAs),a class of endogenous RNA molecules,are produced by alternative splicing of precursor RNA and are covalently linked at the 5′and 3′ends.Recent studies have revealed that dysregulated circ RNAs are closely related to the occurrence and progression of gastrointestinal malignancies.Accumulating evidence indicates that circ RNAs,including circ PVT1,circ LARP4,circ-SFMBT2,cir-ITCH,circ RNA_100782,circ_100395,circ-DONSON,hsa_circ_0001368,circ NRIP1,circ FAT1(e2),circ CCDC66,circ SMARCA5,circ-ZNF652,and circ_0030235 play important roles in the proliferation,differentiation,invasion,and metastasis of cancer cells through a variety of mechanisms,such as acting as micro RNA sponges,interacting with RNA-binding proteins,regulating gene transcription and alternative splicing,and being translated into proteins.With the characteristics of high abundance,high stability,extensive functions,and certain tissue-,time-and diseasespecific expressions,circ RNAs are expected to provide novel perspectives for the diagnoses and treatments of gastrointestinal malignancies.Xueping Tao Yongfu Shao Jianing Yan Liyang Yang Qihua Ye Qingling Wang Rongdan Lu Junming Guo 2021Cancer Biology & Medicine2021,18,2:2
20Development and validation of atmospheric gene flow model for assessing environmental risks from transgenic corn crops显示文摘Pollen-mediated gene flow from genetically modified plants to non-target plants is a concern of crop growers,seed companies,the general public,and the scientific communities.Although there have been descriptive and mechanistic models to describe pollen dispersion,there has rarely been a comprehensive mechanistic model to dynamically simulate pollen release,dispersion,and deposition and to finally relate them to the gene flow(outcrossing).This research developed and validated such a comprehensive mechanistic model for corn crop gene flow risk management.Dynamic pollen dispersion and deposition were predicted by a 3-D random walk model according to inputs of weather data and plant and domain characteristics.Actual gene flow(outcrossing ratio)was obtained according to predicted grand total deposition flux at silk height during the whole pollination season.The model was validated by experimental data and was appropriate to predict gene flow with acceptable accuracy under different atmospheric and environmental conditions;on average,the ratios of measured and simulated values ranged from 0.82 to 1.21,while R2 ranged from 0.56 to 0.68.The model can be easily adapted for other genetically modified crops.Junming Wang Xiusheng Yang 2010International Journal of Agricultural and Biological Engineering2010,3,2:2
