| 1 | Whole-Genome Resequencing of a Worldwide Collection of Rapeseed Accessions Reveals the Genetic Basis of Ecotype Divergence显示文摘Rapeseed (Brassica napus),an important oilseed crop,has adapted to diverse climate zones and latitudes by forming three main ecotype groups,namely winter,semiwinter,and spring types. However,genetic variations underlying the divergence of these ecotypes are largely unknown. Here,we report the global pattern of genetic polymorphisms in rapeseed determined by resequencing a worldwide collection of 991 germplasm accessions.A total of 5.56 and 5.53 million singlenucleotide polymorphisms (SNPs)as Well as 1.86 and 1.92 million InDels were identified by mapping reads to the reference genomes of 'Darmor-bzh'and 'Tapidor,'respectively.We generated a map of allelic drift paths that shows splits and mixtures of the main populations,and revealed an asymmetric evolution of the two subgenomes of B.napus by calculating the genetic diversity and linkage disequilibrium parameters.Selective-sweep analysis revealed genetic changes in genes orthologous to those regulating various aspects of plant development and response to stresses.A genome-wide association study identified SNPs in the promoter regions of FLOWERING LOCUS T and FLOWERING LOCUS C orthologs that corresponded to the different rapeseed ecotype groups. Our study provides important insights into the genomic footprints of rapeseed evolution and flowering-time divergence among three ecotype groups,and will facilitate screening of molecular markers for accelerating rapeseed breeding. | Dezhi Wu Zhe Liang Tao Yan Ying Xu Lijie Xuan Juan Tang Gang Zhou Ulrike Lohwasser Shuijin Hua Haoyi Wang Xiaoyang Chen Qian Wang Le Zhu Antony Maodzeka Nazim Hussain Zhilan Li Xuming Li Imran Haider Shamsi Ghulam Jilani Linde Wu Hongkun Zheng Guoping Zhang Boulos Chalhoub Lisha Shen Hao Yu Lixi Jiang | 2019 | Molecular Plant2019,12,1: | 10 |
| 2 | Detection of Tocopherol in Oilseed Rape (Brassica napus L.) Using Gas Chromatography with Flame Ionization Detector显示文摘The variation among Chinese genotypes of Brassica napus L.for seed tocopherols content and their analysis using gas chromatography has not been comprehensively reported till to date.In the present study,the tocopherol contents of four Chinese genotypes of Brassica napus L.,namely,Gaoyou 605,Zhejiang 619,Zheshuang 758,and Zheshuang 72,were evaluated using three modified sample preparation protocols(P1,P2,and P3) for tocopherol extraction.These methods were distinguished as follows.Protocol one(P1) included the evaporation of solvent after extraction without silylation.Protocol two(P2) followed the direct supernatant collection after overnight extraction without drying and silylation.Protocol three(P3) included trimethylsilylation with N,O-bis(trimethylsilyl) trifluoroacetamide.Genotypic comparison of tocopherol and its isoforms revealed that Gaoyou 605 was dominant over the other genotypes with(140.5±10.5),(316.2± 9.2),and(559.1±24.3) μg g-1 of seed meal α-,γ-,and total(T-) tocopherol,respectively,and a 0.44±0.04 α-to γ-tocopherol ratio.The comparison of the sample preparation protocols,on the other hand,suggests that P3 is the most suitable method for the tocopherol extraction from Brassica oilseeds and for the analysis of tocopherols using gas chromatography flame ionization detector(GC-FID).Trimethylsilylation is the key step differentiating P3 from P1 and P2.Variations detected in tocopherol contents among the Chinese rapeseed(B.napus) genotypes signify the need to quantify a wide range of rapeseed germplasm for seed tocopherol dynamics in short and crop improvement in long. | Nazim Hussain Zahra Jabeen LI Yuan-long CHEN Ming-xun LI Zhi-lan GUO Wan-li Imran Haider Shamsi CHEN Xiao-yang JIANG Li-xi | 2013 | Journal of Integrative Agriculture2013,12,5: | 6 |
| 3 | Interactions of cadmium and aluminum toxicity in their effect on growth and physiological parameters in soybean显示文摘The effect of Al and Cd on the growth, photosynthesis, and accumulation of Al, Cd and plant nutrients in two soybean genotypes were determined using hydroponic culture. There were six treatments: pH 6.5; pH 4.0; pH 6.5+1.0 μmol/L Cd; pH 4.0+1.0 μmol/L Cd; pH 4.0+150 μmol/L Al; pH 4.0+1.0 μmol/L Cd+150 μmol/L Al. The low pH (4.0) and Al treatments caused marked reduction in root length, shoot height, dry weight, chlorophyll content (SPAD value) and photosynthetic rate. Al-sensitive cv. Zhechun 2 accumulated comparatively more Al and Cd in plants than Al-tolerant cv. Liao 1. Compared with pH 6.5, pH 4.0 resulted in significant increase in Cd and Al concentration in plants. Combined application of Cd and Al enhanced their accu-mulation in roots, but caused a reduction in shoots. The concentrations of all 10 nutrients (P, K, Ca, Mg, Fe, Mn, Cu, Zn and B), except Mo were also increased when plants were exposed to pH lower than pH 6.5. Al addition caused a reduction in the con-centration of most nutrients in plant roots and shoots; but K, Mn and Zn in roots were increased. Treatments with Cd alone or together with Al reduced the concentrations of all the plant nutrients in plants. Al-sensitive genotype Zhechun 2 has lower nutrient concentration than Al-tolerant genotype Liao 1. The current findings imply that Al and Cd are synergistic in their effect on plant growth, physiological traits and nutrient uptake. | SHAMSI Imran Haider JILANI Ghulam | 2007 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2007,8,3: | 5 |
| 4 | Synergistic interaction of NaCl and Cd on growth and photosynthetic parameters in soybean genotypes differing in salinity tolerance显示文摘The effects of salinity(50 mmol/L NaCl) and Cd(1 μmol/L CdCl2) as sole and combined on growth and photosyn-thetic parameters were studied using two soybean genotypes,Huachun 18 and NGB.The concentrations of Cd2+,Zn2+,Ca2+,Mg2+,K+ and Na+ were also determined in seeds and pods.Huachun 18 suffered a more serious decrease than NGB in net photosynthetic rate(Pn) in the treatments of salinity stress alone and combined stress(NaCl+Cd),showing that it is relatively sensitive to salinity.The decrease in Pn caused by salt stress in Huachun 18 was mainly due to the reduced total chlorophyll content and photosynthetic efficiency(the ratio of variable fluorescence to maximal fluorescence,Fv/Fm),whereas the decease in NGB was mainly related to reduced stomatal conductance(Gs).The combined stress of both Na and Cd did not induce further decrease in photosynthesis and fluorescence in the two genotypes relative to salt or Cd stress alone.Greater change in the pod concentrations of Zn2+,Ca2+,Mg2+,K+ and Na+ was detected under salt stress for Huachun 18 than for NGB.The results suggested that the interactive effect of NaCl-Cd on growth and nutrient uptake differs between the two soybean genotypes. | SHAMSI Imran Haider | 2007 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2007,8,4: | 3 |

| 6 | Alleviation of arsenic toxicity by phosphate is associated with its regulation of detoxification,defense,and transport gene expression in barley显示文摘Arsenic(As) contamination in soils has posed a severe threat to safe crop production. The previous studies showed the antagonism between phosphorus(P) and As in plant growth and As uptake, while the mechanisms of alleviating As toxicity by P is not completely clear. Due to the limiting P condition, it is imperative to understand how low P addition can be used to suppress arsenate As(V) uptake and the subsequent mechanisms involved. Thus in this study we investigated the effect of P addition on As uptake, anti-oxidative enzyme activity, and anti-oxidant content, and the relative expression of transport, defense, and detoxification genes using two barley genotypes differing in As toxicity tolerance. P addition significantly reduced As concentration in plant tissues, and caused the great changes in activities of catalase and superoxide dismutase, glutathione content, and the relative expression of examined genes when the plants of the two barley genotypes were exposed to 100 μmol L^(–1) As, with ZDB160(As-tolerant) being much more affected than ZDB475(As-sensitive). The current results show that P addition can alleviate As toxicity by regulating the expression of As transport, defense, and detoxification genes to a greater extent in As tolerance of barley, suggesting the possibility of controlling As uptake and toxicity by applying low amount of P fertilizers in the As-contaminated soils. | Gerald Zvobgo Jonas Lwalaba Wa Lwalaba Tichaona Sagonda James Mutemachani Mapodzeke Noor Muhammad Imran Haider Shamsi ZHANG Guo-ping | 2019 | Journal of Integrative Agriculture2019,18,2: | 2 |
| 7 | Physiological and biochemical appraisal for mulching and partial rhizosphere drying of cotton显示文摘Water is the main factor for the healthy life of plant.One of the main negative effects of climate change is the increasing scarcity of water that is lethal for plant.Globally,for water deficit regions(arid and semi-arid),drought is the main factor responsible for low production of agriculture,especially for cotton.Great efforts have been and are being made to find alternatives to water saving practices.This study aimed to examine the effects of partial rhizosphere drying(PRD,half of the root system irrigated at one event,and the other half irrigated in the next event,and so on)with and/or without various mulching treatments on physiological and biochemical traits of cotton.To explore this objective,we laid out experiments in completely randomized design with factorial arrangement in the Islamia University of Bahawalpur,Pakistan in 2016.Two factors included were four mulching treatments(M0,no mulching;M1,black plastic mulching;M2,wheat straw mulching;and M3,cotton sticks mulching)and two irrigation levels(I0,control(full irrigation);and I1,PRD).Fisher's analysis of variance among means of treatments was compared using least significant difference test at 5% probability level.Results revealed that the maximum plant height,leaf area,leaf gas exchange(photosynthetic rate and stomata conductance),chlorophyll,proline and total sugar contents,and enzyme activities were higher under M2 than under other three mulching treatments.As for irrigation levels,higher values of plant height,photosynthesis and water related parameters(leaf water potential,leaf osmotic potential,leaf turgor potential,etc.)were recorded.Contents of total sugar and proline and activities of antioxidant enzymes were significantly higher in PRD-treated plants than in control plants.It was concluded that combined application of PRD and mulching was more effective than the rest of the treatments used in the experiment.Similar study can be conducted in the field by applying irrigation water in alternate rows in semi-arid regions. | Rashid IQBAL Muhammad A S RAZA Muhammad F SALEEM Imran H KHAN Salman AHMAD Muhammad S ZAHEER Muhammad U ASLAM Imran HAIDER | 2019 | Journal of Arid Land2019,11,5: | 2 |

| 9 | 锌和硅对2种水稻基因型的镉毒害及矿质元素转移的影响(英文)显示文摘为探究在镉(Cd)胁迫处理下锌(Zn)和硅(Si)对水稻中矿质元素从根到地上部转移的长期影响,以水稻耐镉基因型秀水110和镉敏感基因型HIPJ 1为供试材料,设置8个处理组合:3个Si处理水平(0,5,15μmol/L Na_2Si O_3·9H_2O)、3个Zn处理水平(0,1,10μmol/L Zn SO_4·7H_2O)和2个Cd处理水平(0,15μmol/L Cd Cl_2),测定其植株生物量、光合强度、抗氧化酶活性、脂质过氧化强度和矿质元素浓度。结果显示,Si(15μmol/L)或Zn(10μmol/L)可有效缓解Cd(15μmol/L)毒害对水稻植株生长的抑制效应,且以Zn的缓解效果更好。在Cd(15μmol/L)胁迫下添加Si(15μmol/L)或Zn(10μmol/L)可有效降低2个水稻基因型叶片中的丙二醛含量,并增强两者叶片中的过氧化氢酶活性,且以在秀水110中的效果更好。单一Zn或Si处理和Zn-Si复合处理均可减少HIPJ 1中的Cd^(2+)从根至地上部的转运。此外,Cd能显著降低水稻植株体内Ca、Mn、Mg等矿质元素的转运。单一Zn处理能够显著促进植物生长,且效果好于单一Si处理与Zn-Si联合处理。但是Zn-Si复合处理对提高Cd胁迫下矿质元素的吸收效果并不显著。 | MAPODZEKE James Mutemachani SAGONDA Tichaona SEHAR Shafaque 张欣 黄雨晴 ZVOBGO Gerald MAODZEKA Antony LWALABA WA LWALABA Jonas SHAMSI Imran Haider | 2018 | 浙江大学学报(农业与生命科学版)2018,44,3: | 2 |

| 11 | Effect of Annealing on the Optical Properties of GaN Films Grown by Pulsed Laser Deposition显示文摘In the present study,gallium nitride thin films were grown by using pulsed laser deposition.After the growth samples were annealed at 400 and 600℃in the nitrogen atmosphere.Surface morphology of the as-grown and annealed samples was observed by atomic force microscopy.Post-growth annealing results in an improved surface roughness of the films.Chemical analysis of the samples was performed by X-ray photoelectron spectroscopy.Stoichiometric gallium nitride thin films were obtained for the samples annealed at 600℃.Optical measurements of the samples were performed to measure the band gap and optical constants of the films.Effect of annealing on the band gap and optical constants of the films was studied. | M.Baseer Haider M.F.Al-Kuhaili S.M.A.Durrani Imran Bakhtiari | 2013 | Journal of Materials Science & Technology2013,29,8: | 1 |
| 12 | Galerkin Finite Element Study on the Effects of Variable Thermal Conductivity and Variable Mass Diffusion Conductance on Heat and Mass Transfer显示文摘This article investigates the effects of variable thermal conductivity and variable mass diffusion coefficient on the transport of heat and mass in the flow of Casson fluid. Numerical simulations for two-dimensional flow induced by stretching surface are performed by using Galerkin finite element method(GFEM) with linear shape functions. After assembly process, nonlinear algebraic equations are linearized through Picard method and resulting linear system is solved iteratively using Gauss Seidal method with simulation tolerance 10^(-8). Maximum value of independent variableη is searched through numerical experiments. Grid independent study was carried out and error analysis is performed.Simulated results are validated by comparing with already published results. Parametric study is carried out to explore the physics of the flow. The concentration increases when mass diffusion coefficient is increased. The concentration and thermal boundary layer thicknesses increase when ?_1 and ? are increased. The effect of generative chemical reaction on concentration is opposite to the effect of destructive chemical reaction on the concentration. | Imran Haider Qureshi M.Nawaz Shafia Rana T.Zubair | 2018 | Communications in Theoretical Physics2018,69,7: | 1 |

| 17 | Reimagining safe lithium applications in the living environment and its impacts on human,animal,and plant system显示文摘Lithium's(Li)ubiquitous distribution in the environment is a rising concern due to its rapid proliferation in the modern electronic industry.Li enigmatic entry into the terrestrial food chain raises many questions and uncertainties that may pose a grave threat to living biota.We examined the leverage existing published articles regarding advances in global Li resources,interplay with plants,and possible involvement with living organisms,especially humans and animals.Globally,Li concentration(<10 e300 mg kg1)is detected in agricultural soil,and their pollutant levels vary with space and time.High mobility of Li results in higher accumulation in plants,but the clear mechanisms and specific functions remain unknown.Our assessment reveals the causal relationship between Li level and biota health.For example,lower Li intake(<0.6 mM in serum)leads to mental disorders,while higher intake(>1.5 mM in serum)induces thyroid,stomach,kidney,and reproductive system dysfunctions in humans and animals.However,there is a serious knowledge gap regarding Li regulatory standards in environmental compartments,and mechanistic approaches to unveil its consequences are needed.Furthermore,aggressive efforts are required to define optimum levels of Li for the normal functioning of animals,plants,and humans.This review is designed to revitalize the current status of Li research and identify the key knowledge gaps to fight back against the mountainous challenges of Li during the recent digital revolution.Additionally,we propose pathways to overcome Li problems and develop a strategy for effective,safe,and acceptable applications. | Noman Shakoor Muhammad Adeel Muhammad Arslan Ahmad Muhammad Zain Usman Waheed Rana Arsalan Javaid Fasih Ullah Haider Imran Azeem Pingfan Zhou Yuanbo Li Ghulam Jilani Ming Xu Jorg Rinklebe Yukui Rui | 2023 | Environmental Science and Ecotechnology2023,,3: | 0 |

| 19 | 基于正负热膨胀效应调节上转换和近红外下转移发光实现多参数温度传感显示文摘稀土掺杂发光材料在高温下会发生热猝灭,极大地限制了其在高温区域的应用.随着温度的增加,稀土掺杂负热膨胀材料中稀土离子之间的距离减小,从而实现热增强.然而,目前的研究主要集中于负热膨胀材料在可见光区域的上转换和下转移发光,而很少关注近红外发光的热增强.本文中制备的Yb_(2)W_(3)O_(12):Er负热膨胀材料实现了上转换和近红外下转移发光热增强.当温度从293 K增加到573 K时,Er^(3+)的绿色上转换发光增加了27倍,近红外下转移发光增加了87倍.本文还制备了负热膨胀Yb_(2)W_(3)O_(12):Er荧光粉和正热膨胀CaWO_(4):Yb/Er的混合荧光粉,解决了非接触荧光强度比温度传感器热耦合能级的限制.基于荧光强度比(I860/I525,I860/I675,I1550/I525,和I1550/I675)的最大相对灵敏度分别为2.04%K^(−1),2.15%K^(−1),2.01%K^(−1)和2.09%K^(−1),表明其在温度传感器中的潜在应用. | 陈志浩 寸阳珂 闫世磊 字映竹 朱博坤 阮柯亮 丁伯杰 杨正猛 Asif Ali Haider Imran Khan Cherkasova Tatiana 邱建备 黄安君 刘月 杨正文 | 2023 | Science China Materials2023,66,12: | 0 |
