1Ideotype root architecture for efficient nitrogen acquisition by maize in intensive cropping systems显示文摘The use of nitrogen(N) fertilizers has contributed to the production of a food supply sufficient for both animals and humans despite some negative environmental impact.Sustaining food production by increasing N use efficiency in intensive cropping systems has become a major concern for scientists,environmental groups,and agricultural policymakers worldwide.In high-yielding maize systems the major method of N loss is nitrate leaching.In this review paper,the characteristic of nitrate movement in the soil,N uptake by maize as well as the regulation of root growth by soil N availability are discussed.We suggest that an ideotype root architecture for efficient N acquisition in maize should include(i) deeper roots with high activity that are able to uptake nitrate before it moves downward into deep soil;(ii) vigorous lateral root growth under high N input conditions so as to increase spatial N availability in the soil;and(iii) strong response of lateral root growth to localized nitrogen supply so as to utilize unevenly distributed nitrate especially under limited N conditions.MI GuoHua,CHEN FanJun,WU QiuPing,LAI NingWei,YUAN LiXing & ZHANG FuSuo* Key Laboratory of Plant Nutrition,MOA Key Laboratory of Plant-Soil Interaction,MOE College of Resources and Environmental Science,China Agricultural University,Beijing 100193,China 2010Science China(Life Sciences)2010,53,12:35
2Evaluation of the yield and nitrogen use efficiency of the dominant maize hybrids grown in North and Northeast China显示文摘Breeding high-yielding and nutrient-efficient cultivars is one strategy to simultaneously resolve the problems of food security,resource shortage,and environmental pollution.However,the potential increased yield and reduction in fertilizer input achievable by using high-yielding and nutrient-efficient cultivars is unclear.In the present study,we evaluated the yield and nitrogen use efficiency(NUE) of 40 commercial maize hybrids at five locations in North and Northeast China in 2008 and 2009.The effect of interaction between genotype and nitrogen(N) input on maize yield was significant when the yield reduction under low-N treatment was 25%-60%.Based on the average yields achieved with high or low N application,the tested cultivars were classified into four types based on their NUE:efficient-efficient(EE) were efficient under both low and high N inputs,high-N efficient(HNE) under only high N input,low-N efficient(LNE) under only low N input,and nonefficient-nonefficient under neither low nor high N inputs.Under high N application,EE and HNE cultivars could potentially increase maize yield by 8%-10% and reduce N input by 16%-21%.Under low N application,LNE cultivars could potentially increase maize yield by 12%.We concluded that breeding for N-efficient cultivars is a feasible strategy to increase maize yield and/or reduce N input.CHEN FanJun FANG ZenGuo GAO Qiang YE YouLiang JIA LiangLiang YUAN LiXing MI GuoHua ZHANG FuSuo 2013Science China(Life Sciences)2013,56,6:27
3Mechanism of electroacupuncture on inflammatory pain: neural-immune-endocrine interactions显示文摘Nociceptive signals are transmitted by peripheral afferents to the central nervous system under pain condition, a process that involves various neurotransmitters and pathways. Electroacupuncture (EA) has been widely used as a pain management technique in clinical practice. Emerging studies have shown that EA can inhibit the induction and transmission of pain signals and, consequently, mediate anti-nociceptive and anti-inflammatory effects by rebalancing the neural-immune-endocrine interactions. This review summarizes the neural-immune- endocrine circuit including peripheral afferent and central efferent, contributing to EA-induced neuroimmune and neuroendocrine modulation in inflammatory pain models. The peripheral afferent circuit includes crosstalk among immune cells, inflammatory cytokines, peripheral nociceptors. In central efferent primarily involves the neuroinflammatory interactions between spinal nociceptive neurons and glial cells. Furthermore, the hypothalamic- pituitary-adrenal axis, sympathetic and vagal nervous may serve as an essential pathway involved in the mechanism of acupuncture-mediated analgesia within the interactions of the central, immune and endocrine systems. Overall, this review focuses on the interactions of neural-immune-endocrine in inflammatory pain, which may be underlying the mechanism of EA-induced anti-inflammatory and antinociceptive effect.Li Yuan Yang Mingxiao Wu Fan Cheng Ke Chen Haiyong Shen Xueyong Lao Lixing 2019Journal of Traditional Chinese Medicine2019,39,5:20
4Root growth in response to nitrogen supply in Chinese maize hybrids released between 1973 and 2009显示文摘Root growth has a fundamental role in nitrogen (N) use efficiency.Nevertheless,little is known about how modern breeding progress has affected root growth and its responses to N supply.The root and shoot growth of a core set of 11 representative Chinese maize (Zea mays L.) hybrids released between 1973 and 2009 were investigated under high N (4 mmol L?1,HN) and low N (0.04 mmol L?1,LN) levels in a solution culture system.Compared with LN,HN treatment decreased root dry weight (RDW),the root:shoot ratio (R/S),and the relative growth rate for root dry weight (RGRroot),but increased the total root length (TRL) and the total lateral root length (LRL).The total axial root length (ARL) per plant was reduced under HN,mostly in hybrids released before the 1990s.The number of seminal roots (SRN) was largely unaffected by different N levels.More recently released hybrids showed higher relative growth rates in the shoot under both HN and LN.However,the roots only showed increased RGR under HN treatment.Correspondingly,there was a positive linear relationship with the year of hybrid release for TRL,LRL and ARL under HN treatment.Together,these results suggest that while shoot growth of maize has improved,its root growth has only improved under high N conditions over the last 36 years of selective breeding in China.Improving root growth under LN conditions may be necessary to increase the N use efficiency of maize.WU QiuPing CHEN FanJun CHEN YanLing YUAN LiXing ZHANG FuSuo MI GuoHua 2011Science China(Life Sciences)2011,54,7:15
5The role of maize root size in phosphorus uptake and productivity of maize/faba bean and maize/wheat intercropping systems显示文摘Interspecific root/rhizosphere interactions affect phosphorus (P) uptake and the productivity of maize/faba bean and maize/wheat intercropping systems. The aim of these experiments was to determine whether manipulation of maize root growth could improve the productivity of the two intercropping systems. Two near isogenic maize hybrids (the larger-rooted T149 and smaller-rooted T222) were intercropped with faba bean and wheat, under conditions of high- and low-P availability. The larger-rooted T149 showed greater competitive ability than the smaller-rooted T222 in both maize/faba bean and maize/wheat intercropping systems. The higher competitive ability of T149 improved the productivity of the maize/faba bean intercropping system in P-sufficient conditions. In maize/wheat intercropping systems, root growth, shoot biomass, and P uptake of maize were inhibited by wheat, regardless of the P-supply. Compared with T222, the larger-rooted T149 suffered less in the intercropping systems. The total biomass of the maize/wheat intercropping system was higher for wheat/T149 than for wheat/T222 under low-P conditions. These data suggested that genetic improvement of maize root size could enhance maize growth and its ability to compete for P resources in maize/faba bean and maize/wheat intercropping systems. In addition, depending on the P availability, larger maize roots could increase the productivity of intercropping systems.ZHANG YiKai CHEN FanJun LI Long CHEN YanHua LIU BingRan ZHOU YuLing YUAN LiXing ZHANG FuSuo MI GuoHua 2012Science China(Life Sciences)2012,55,11:13

7Use of genotype-environment interactions to elucidate the pattern of maize root plasticity to nitrogen deficiency显示文摘Maize(Zea mays L.) root morphology exhibits a high degree of phenotypic plasticity to nitrogen(N) de ficiency,but the underlying genetic architecture remains to be investigated Using an advanced BC_4F_3 population,we investigated the root growth plasticity under two contrasted N levels and identi fied the quantitative trait loci(QTLs) with QTL-environment(Q×E)interaction effects. Principal components analysis(PCA) on changes of root traits to N de ficiency(D LN-HN) showed that root length and biomass contributed for 45.8% in the same magnitude and direction on the first PC,while root traits scattered highly on PC_2 and PC_3. Hierarchical cluster analysis on traits for D LN-HN further assigned the BC_4F_3 lines into six groups,in which the special phenotypic responses to N de ficiency was presented These results revealed the complicated root plasticity of maize in response to N de ficiency that can be caused by genotype environment(G×E) interactions. Furthermore,QTL mapping using a multi-environment analysis identi fied 35 QTLs for root traits. Nine of these QTLs exhibited signi ficant Q×E interaction effects. Taken together,our findings contribute to understanding the phenotypic and genotypic pattern of root plasticity to N de ficiency,which will be useful for developing maize tolerance cultivars to N de ficiency.Pengcheng Li Zhongjuan Zhuang Hongguang Cai Shuai Cheng Ayaz Ali Soomro Zhigang Liu Riliang Gu Guohua Mi Lixing Yuan Fanjun Chen 2016Journal of Integrative Plant Biology2016,58,3:8
8Do anogenital gland secretionsof giant panda code for their sexual ability?显示文摘To test the hypothesis of whether ano- genital gland secretions (AGS) of giant panda code for their sexual ability, we collected AGS samples of 11 male (5 adult and 6 subadult) and 14 female (7 adult and 7 subadult) captive giant pandas (Ailuro- poda melanoleuca) from China Research and Con- servation Center for the Giant Panda at Wolong, Si- chuan, China from 1994 to 2002. The samples were analyzed by GC and GC-MS. The GC results showed that male and female pandas shared 20 constituents with equal capacity factors in the AGS. Further GC-MS analyses showed that there were a total of 95 compounds in the AGS. Nine constituents for the males and three for the females differed significantly in relative abundances between sexually active and inactive individuals, but no clear division between sexually active and inactive pandas by hierarchical cluster analyses on the relative abundances of a subset of 56 compounds. However, we were able to separate different age groups of male pandas by the constituents of AGS. 14 compounds were found sig- nificantly and negatively, and 8 compounds positively, correlated with pandas’ age by year. Our results suggest that the information contained in the AGS of panda might not code for pandas’ sexual ability but might for their age. These results will be valuable for captive breeding and conservation in the wild.LIU Dingzhen YUAN Hong TIAN Hong WEI Rongping ZHANG Guiquan SUN Lixing WANG Liwen SUN Ruyong 2006Chinese Science Bulletin2006,51,16:7
9Male panda (Ailuropoda melanoleuca) urine contains kinship information显示文摘Chemical communication plays an important role in kin selection and mate choice in mammals. The covariance of odor-genes of rodents has been documented and kinship odor has been proposed and termed, yet little is known of the relationship between genetic relatedness and chemical composition of kinship odors. Giant pandas (Ailuropoda melanoleuca) rely substantially on chemical communication to mediate their social interactions. To examine the relationship between genetic relatedness and compounds in the urine/anogenital gland secretions, we compared the similarities between genetic relatedness and the chemical profiles of anogenital gland secretions and urine via lineage construction and GC-MS (gas chromatography and mass spectrometry). We found that information about kinship odors was present only in the urine of male adults in the mating season but absent in the non-mating season. Adult females and all sub-adults did not have such kinship odors in either mating or non-mating season. Therefore, kinship odor in the panda was contingent on age, sex, and season. This is the first report about the condition-dependent expression of kinship odor, which may have a sig- nificant implication in the practice of panda conservation in relation to chemical communication and sexual selection.LIU DingZhen WEI RongPing ZHANG GuiQuan YUAN Hong WANG ZhiPeng SUN Lixing ZHANG Jianxu ZHANG HeMin 2008Chinese Science Bulletin2008,53,18:6

11Innovations of phosphorus sustainability:implications for the whole chain显示文摘Phosphorus(P)is a non-renewable resource,therefore ensuring global food and environmental security depends upon sustainable P management.To achieve this goal,sustainable P management in the upstream and downstream sectors of agriculture from mineral extraction to food consumption must be addressed systematically.The innovation and feasibility of P sustainability are highlighted from the perspective of the whole P-based chain,including the mining and processing of P rock,production of P fertilizers,soil and rhizosphere processes involving P,absorption and utilization of P by plants,P in livestock production,as well as flow and management of P at the catchment scale.The paper also emphasizes the importance of recycling P and the current challenges of P recovery.Finally,sustainable solutions of holistic P management are proposed from the perspective of technology improvement with policy support.Jianbo SHEN Liyang WANG Xiaoqiang JIAO Fanlei MENG Lin ZHANG Gu FENG Junling ZHANG Lixing YUAN Lin MA Yong HOU Tao ZHANG Weifeng ZHANG Guohua LI Kai ZHANG Fusuo ZHANG 2019Frontiers of Agricultural Science and Engineering2019,6,4:4
12Importers Drive Leaf-to-Leaf Jasmonic Acid Transmission in Wound-Induced Systemic Immunity显示文摘The transmission of mobile wound signals along the phloem pathway is essential to the activation of wound-induced systemic response/resistance,which requires an upsurge of jasmonic acid(JA)in the distal undamaged leaves.Among these mobile signals,the electrical signal mediated by the glutamate-dependent activation of several clade three GLUTAMATE RECEPTOR-LIKE(GLR3)proteins is involved in the stimulation of JA production in distal leaves.However,whether JA acts as a mobile wound signal and,if so,how it is transmitted and interacts with the electrical signal remain unclear.Here,we show that JA was translocated from the local to distal leaves in Arabidopsis,and this process was predominantly regulated by two phloem-expressed and plasma membrane-localized jasmonate transporters,AtJAT3 and AtJAT4.In addition to the cooperation between AtJAT3/4 and GLR3.3 in the regulation of long-distance JA translocation,our findings indicate that importer-mediated cell-cell JA transport is important for driving the loading and translocation of JA in the phloem pathway in a self-propagating manner.Mengya Li Feifei Wang Shuangzhang Li Guanghui Yu Lijian Wang Qingqing Li Xiangyu Zhu Zhen Li Lixing Yuan Pei Liu 2020Molecular Plant2020,13,10:3
13Enhancing phosphorus uptake efficiency through QTL-based selection for root system architecture in maize显示文摘Root system architecture(RSA) plays an important role in phosphorus(P) acquisition,but enhancing P use efficiency(PUE) in maize via genetic manipulation of RSA has not yet been reported.Here,using a maize recombinant inbred line(RIL) population,we investigated the genetic relationships between PUE and RSA,and developed P-efficient lines by selection of quantitative trait loci(QTLs) that coincide for both traits.In low-P(LP) fields,P uptake efficiency(Pup E) was more closely correlated with PUE(r =0.48-0.54),and RSA in hydroponics was significantly related to Pup E(r=0.25-0.30) but not to P utilization efficiency(Put E).QTL analysis detected a chromosome region where two QTLs for PUE,three for Pup E and three for RSA were assigned into two QTL clusters,Cl-bin3.04 a and Cl-bin3.04 b.These QTLs had favorable effects from alleles derived from the large-rooted and high-Pup E parent.Marker-assisted selection(MAS) identified nine advanced backcross-derived lines carrying Cl-bin3.04 a or Cl-bin3.04 b that displayed mean increases of 22%e26% in PUE in LP fields.Furthermore,a line L224 pyramiding Clbin3.04 a and Cl-bin3.04 b showed enhanced Pup E,relying mainly on changes in root morphology,rather than root physiology,under both hydroponic and field conditions.These results highlight the physiological and genetic contributions of RSA to maize Pup E,and provide a successful study case of developing P-efficient crops through QTL-based selection.Riliang Gu Fanjun Chen Lizhi Long Hongguang Cai Zhigang Liu Jiabo Yang Lifeng Wang Huiyong Li Junhui Li Wenxin Liu Guohua Mi Fusuo Zhang Lixing Yuan 2016Journal of Genetics and Genomics2016,43,11:3
14Experimental Gaussian Boson sampling显示文摘Gaussian Boson sampling(GBS) provides a highly efficient approach to make use of squeezed states from parametric down-conversion to solve a classically hard-to-solve sampling problem. The GBS protocol not only significantly enhances the photon generation probability, compared to standard Boson sampling with single photon Fock states, but also links to potential applications such as dense subgraph problems and molecular vibronic spectra. Here, we report the first experimental demonstration of GBS using squeezed-state sources with simultaneously high photon indistinguishability and collection efficiency.We implement and validate 3-, 4- and 5-photon GBS with high sampling rates of 832, 163 and 23 kHz,respectively, which is more than 4.4, 12.0, and 29.5 times faster than the previous experiments.Further, we observe a quantum speed-up on a NP-hard optimization problem when comparing with simulated thermal sampler and uniform sampler.Han-Sen Zhong Li-Chao Peng Yuan Li Yi Hu Wei Li Jian Qin Dian Wu Weijun Zhang Hao Li Lu Zhang Zhen Wang Lixing You Xiao Jiang Li Li Nai-Le Liu Jonathan P.Dowling Chao-Yang Lu Jian-Wei Pan 2019Science Bulletin2019,64,8:3
15A NEW APPROACH TO HOLISTIC NITROGEN MANAGEMENT IN CHINA显示文摘Since the 1980s,the widespread use of N fertilizer has not only resulted in a strong increase in agricultural productivity but also caused a number of environmental problems,induced by excess reactive N emissions.A range of approaches to improve N management for increased agricultural production together with reduced environmental impacts has been proposed.The 4R principles(right product,right amount,right time and right place)for N fertilizer application have been essential for improving crop productivity and N use efficiency while reducing N losses.For example,site-specific N management(as part of 4R practice)reduced N fertilizer use by 32%and increased yield by 5%in China.However,it has not been enough to overcome the challenge of producing more food with reduced impact on the environment and health.This paper proposes a new framework of food-chainnitrogen-management(FCNM).This involves good N management including the recycling of organic manures,optimized crop and animal production and improved human diets,with the aim of maximizing resource use efficiency and minimizing environmental emissions.FCNM could meet future challenges for food demand,resource sustainability and environmental safety,key issues for green agricultural transformation in China and other countries.Xuejun LIU Zhenling CUI Tianxiang HAO Lixing YUAN Ying ZHANG Baojing GU Wen XU Hao YING Weifeng ZHANG Tingyu LI Xiaoyuan YAN Keith GOULDING David KANTER Robert HOWARTH Carly STEVENS Jagdish LADHA Qianqian LI Lei LIU Wim DE VRIES Fusuo ZHANG 2022Frontiers of Agricultural Science and Engineering2022,9,3:2

17FUZZY MULTI-LEVEL WAREHOUSE LAYOUT PROBLEM:NEW MODEL AND ALGORITHM显示文摘This paper deals with a multi-level warehouse layout problem under fuzzy environment, in which different types of items need to be placed in a multi-level warehouse and the monthly demand of each item type and horizontal distance traveled by clamp track are treated as fuzzy variables. In order to minimize the total transportation cost, chance-constrained programming model is designed for the problem based on the credibility measure and then tabu search algorithm based on the fuzzy simulation is designed to solve the model. Some mathematical properties of the model are also discussed when the fuzzy variables are interval fuzzy numbers or trapezoidal fuzzy numbers. Finally, a numerical example is presented to show the efficiency of the algorithm.Lixing YANG Yuan FENG 2006Journal of Systems Science and Systems Engineering2006,15,4:1
18Evolving technologies for growing,imaging and analyzing 3D root system architecture of crop plants显示文摘A plant's ability to maintain or improve its yield under limiting conditions,such as nutrient de ficiency or drought,can be strongly in fluenced by root system architecture(RSA),the three-dimensional distribution of the different root types in the soil. The ability to image,track and quantify these root system attributes in a dynamic fashion is a useful tool in assessing desirable genetic and physiological root traits. Recent advances in imaging technology and phenotyping software have resulted in substantive progress in describing and quantifying RSA. We have designed a hydroponic growth system which retains the three-dimensional RSA of the plant root system,while allowing for aeration,solution replenishment and the imposition of nutrient treatments,as well as high-quality imaging of the root system. The simplicity and flexibility of the system allows for modi fications tailored to the RSA of different crop species and improved throughput. This paper details the recent improvements and innovations in our root growth and imaging system which allows for greater image sensitivity(detection of fine roots and other root details),higher ef ficiency,and a broad array of growing conditions for plants that more closely mimic those found under field conditions.Miguel A.Pieros Brandon G.Larson Jon E.Shaff David J.Schneider Alexandre Xavier Falcao Lixing Yuan Randy T.Clark Eric J.Craft Tyler W.Davis Pierre-Luc Pradier Nathanael M.Shaw Ithipong Assaranurak Susan R.Mc Couch Craig Sturrock Malcolm Bennett Leon V.Kochian 2016Journal of Integrative Plant Biology2016,58,3:1
