1Factors affecting genomic selection revealed by empirical evidence in maize显示文摘Genomic selection(GS) as a promising molecular breeding strategy has been widely implemented and evaluated for plant breeding, because it has remarkable superiority in enhancing genetic gain, reducing breeding time and expenditure, and accelerating the breeding process. In this study the factors affecting prediction accuracy(rMG) in GS were evaluated systematically, using six agronomic traits(plant height, ear height, ear length, ear diameter,grain yield per plant and hundred-kernel weight) evaluated in one natural and two biparental populations. The factors examined included marker density, population size, heritability,statistical model, population relationships and the ratio of population size between the training and testing sets, the last being revealed by resampling individuals in different proportions from a population. Prediction accuracy continuously increased as marker density and population size increased and was positively correlated with heritability; rMGshowed a slight gain when the training set increased to three times as large as the testing set. Low predictive performance between unrelated populations could be attributed to different allele frequencies, and predictive ability and prediction accuracy could be improved by including more related lines in the training population. Among the seven statistical models examined, including ridge regression best linear unbiased prediction(RR-BLUP), genomic BLUP(GBLUP), Bayes A, Bayes B, Bayes C, Bayesian least absolute shrinkage and selection operator(Bayesian LASSO), and reproducing kernel Hilbert space(RKHS), the RKHS and additive-dominance model(Add + Dom model) showed credible ability for capturing non-additive effects, particularly for complex traits with low heritability. Empirical evidence generated in this study for GS-relevant factors will help plant breeders to develop GS-assisted breeding strategies for more efficient development of varieties.Xiaogang Liu Hongwu Wang Hui Wang Zifeng Guo Xiaojie Xu Jiacheng Liu Shanhong Wang Wen-Xue Li Cheng Zou Boddupalli M.Prasanna Michael S.Olsen Changling Huang Yunbi Xu 2018The Crop Journal2018,6,4:8
2The Construction of Active Source Repeated Monitoring in the Qilian Mountain, Gansu Province显示文摘The exciting source of the active source repeated monitoring is located in the Xiliushui Reservoir in Zhangye,Gansu Province. The system began operating normally on July 9,2015,and we had completed a period of 40 days of continuous excitation experiment before November 10,2015. Our results reveal that the airgun source has good consistency and repeatability,and the detective system of active source can record signal clearly. The construction of active source repeated exploration projects has achieved some results,which can provide valuable experience for the research of active source repeated exploration. The observation data we obtained makes it possible to follow the temporal and spatial variations of the deep structure of the Qilian Mountain areas.Zhang Yuansheng Guo Xiao Qin Manzhong Liu Xuzhou Wei Congxin Shen Xuzhang Yan Wenhua Zou Rui Yin Liang Wang Yahong Sun Dianfeng Feng Hongwu Zhang Lifeng Guo Yingxia 2016Earthquake Research in China2016,30,3:4

9Regulating off-centering distortion maximizes photoluminescence in halide perovskites显示文摘Metal halide perovskites possess unique atomic and electronic configurations that endow them with high defect tolerance and enable high-performance photovoltaics and optoelectronics.Perovskite light-emitting diodes have achieved an external quantum efficiency of over 20%.Despite tremendous progress,fundamental questions remain,such as how structural distortion affects the optical properties.Addressing their relationships is considerably challenging due to the scarcity of effective diagnostic tools during structural and property tuning as well as the limited tunability achievable by conventional methods.Here,using pressure and chemical methods to regulate the metal off-centering distortion,we demonstrate the giant tunability of photoluminescence(PL)in both the intensity(>20 times)and wavelength(>180 nm/GPa)in the highly distorted halide perovskites[CH_(3)NH_(3)GeI_(3),HC(NH_(2))2GeI_(3),and Cs Ge I_(3)].Using advanced in situ high-pressure probes and first-principles calculations,we quantitatively reveal a universal relationship whereby regulating the level of off-centering distortion towards 0.2 leads to the best PL performance in the halide perovskites.By applying this principle,intense PL can still be induced by substituting CH_(3)NH_(3)^(+)with Cs^(+)to control the distortion in(CH_(3)NH_(3))_(1-x)Cs_(x)GeI_(3),where the chemical substitution plays a similar role as external pressure.The compression of a fully substituted sample of CsGe I_(3)further tunes the distortion to the optimal value at 0.7 GPa,which maximizes the emission with a10-fold enhancement.This work not only demonstrates a quantitative relationship between structural distortion and PL property of the halide perovskites but also illustrates the use of knowledge gained from high-pressure research to achieve the desired properties by ambient methods.Xujie Lv Constantinos Stoumpos Qingyang Hu Xuedan Ma Dongzhou Zhang Songhao Guo Justin Hoffman Kejun Bu Xiaofeng Guo Yingqi Wang Cheng Ji Haijie Chen Hongwu Xu Quanxi Jia Wenge Yang Mercouri G.Kanatzidis Ho-Kwang Mao 2021National Science Review2021,8,9:1
10Thymol ameliorates ammonium toxicity via repressing polyamine oxidase-derived hydrogen peroxide and modulating ammonium transporters in rice root显示文摘Background:Ammonium is an indispensable nutrient for crop growth,but anoxic conditions or inappropriate fertilizer usage result in the increase in ammonium content in soil.Excessive ammonium causes phytotoxicity.Thymol is a kind of natural phenolic compound with anti-microbial properties.However,little is known about the role of thymol in modulating plant physiology.Here we find the novel role of thymol in protecting rice from ammonium toxicity.Results:Thymol remarkably rescued rice seedlings growth from ammonium stress,which may resulted from the attenuation of reactive oxygen species(ROS)accumulation,oxidative injury,and cell death in both shoots and roots.Polyamine oxidase(PAO)metabolizes polyamines to produce ROS in plants in response to stress conditions.Thymol blocked ammonium-induced upregulation of a set of rice PAOs,which contributed to the decrease in ROS content.In rice seedlings upon ammonium stress,thymol downregulate the expression of ammonium transporters(AMT1;1 and AMT1;2);thymol upregulated the expression of calcineurin B-like interacting protein kinase 23(CIPK23)and calcineurin B-like binding protein 1(CBL1),two negative regulators of AMTs.This may help rice avoid ammonium overload in excessive ammonium environment.Correlation analysis indicated that PAOs,AMTs,and CBL1 were the targets of thymol in the detoxification of excessive ammonium.Conclusion:Thymol facilitates rice tolerance against ammonium toxicity by decreasing PAO-derived ROS and modulating ammonium transporters.Such findings may be applicable in the modulation of nutrient acquisition during crop production.Kai Guo Guangchi An Ning Wang Bingdong Pang Zhiqi Shi Hongwu Bai Li Zhang Jian Chen Weimin Xu 2021Food Production, Processing and Nutrition2021,3,1:0
11Lockdown-induced Urban Aerosol Change over Changchun, China During COVID-19 Outbreak with Polarization LiDAR显示文摘Depending on various government policies,COVID-19(Corona Virus Disease-19) lockdowns have had diverse impacts on global aerosol concentrations.In 2022,Changchun a provincial capital city in Northeast China,suffered a severe COVID-19 outbreak and implemented a very strict lockdown that lasted for nearly two months.Using ground-based polarization Light Detection and Ranging(LiDAR),we detected real-time aerosol profile parameters(EC,extinction coefficient;DR,depolarization ratio;AOD,aerosol optical depth),as well as air-quality and meteorological indexes from 1 March to 30 April in 2021 and 2022 to quantify the effects of lockdown on aerosol concentrations.The period in 2022 was divided into three stages:pre-lockdown(1-10 March),strict lockdown(11 March to 10 April),and partial lockdown(11-30 April).The results showed that,during the strict lockdown period,compared with the pre-lockdown period,there were substantial reductions in aerosol parameters(EC and AOD),and this was consistent with the concentrations of the atmospheric pollutants PM_(2.5)(particulate matter with an aerodynamic diameter ≤2.5 μm) and PM_(2.5)(particulate matter with an aerodynamic diameter ≤10 μm),and the Oconcentration increased by 8.3%.During the strict lockdown,the values of EC within0-1 km and AOD decreased by 16.0% and 11.2%,respectively,as compared to the corresponding period in 2021.Lockdown reduced the conventional and organized emissions of air pollutants,and it clearly delayed the time of seasonal emissions from agricultural burning;however,it did not decrease the number of farmland fire points.Considering meteorological factors and eliminating the influence of wind-blown dust events,the results showed that reductions from conventional organized emission sources during the strict lockdown contributed to a 30% air-quality improvement and a 22% reduction in near-surface extinction(0-2 km).Aerosols produced by urban epidemic prevention and disinfection can also be identified using the EC.Regarding seasonal sources of agricultural straw burning,the concentrated burning induced by the epidemic led to the occurrence of heavy pollution from increased amounts of atmospheric aerosols,with a contribution rate of 62%.These results indicate that there is great potential to further improve air quality in the local area,and suggest that the comprehensive use of straw accompanied by reasonable planned burning is the best way to achieve this.CHEN Weiwei DUANMU Lingjian QIN Yang YANG Hongwu FU Jing LU Chengwei FENG Wei GUO Li 2022Chinese Geographical Science2022,32,5:0
12The heterochronic gene Oryza sativa LIKE HETEROCHROMATIN PROTEIN 1 modulates miR156b/c/i/e levels显示文摘The juvenile-to-adult transition in plants involves changes in vegetative growth and plant architecture;the timing of this transition has important implications for agriculture.The microRNA miR156 regulates this transition and shoot maturation in plants.In Arabidopsis thaliana,deposition of histone H3 trimethylation on lysine 27(H3K27me3,a repressive mark)at the MIR156A/C loci is regulated by Polycomb Repressive Complex 1(PRC1)or PRC2,depending on the developmental stage.The levels of miR156 progressively decline during shoot maturation.The amount of H3K27me3 at MIR156A/C loci affects miR156 levels;however,whether this epigenetic regulation is conserved remains unclear.Here,we found that in rice(Oryza sativa),the putative PRC1 subunit LIKE HETEROCHROMATIN PROTEIN 1(OsLHP1),with the miR156–SQUAMOSA PROMOTER BINDING PROTEIN-LIKE(SPL)module,affects developmental phase transitions.Loss of OsLHP1 function results in ectopic expression of MIR156B/C/I/E,phenocopy of miR156 overexpression,and reduced H3k27me3 levels at MIR156B/C/I/E.This indicates that OsLHP1 has functionally diverged from Arabidopsis LHP1.Genetic and transcriptome analyses of wild-type,miR156b/c-overexpression,and Oslhp1-2 mutant plants suggest that OsLHP1 acts upstream of miR156 and SPL during the juvenile-to-adult transition.Therefore,modifying the OsLHP1–miR156–SPL pathway may enable alteration of the vegetative period and plant architecture.Yongtao Cui Jingfei Cheng Shuang Ruan Peipei Qi Wei Liu Hongwu Bian Luhuan Ye Yuping Zhang Jiang Hu Guojun Dong Longbiao Guo Yijing Zhang Qian Qian d Xingming Hu 2020Journal of Integrative Plant Biology2020,62,12:0
13Transcriptional landscapes of de novo root regeneration from detached Arabidopsis leaves revealed by time-lapse and single-cell RNA sequencing analyses显示文摘Detached Arabidopsis thaliana leaves can regenerate adventitious roots,providing a platformfor studying de novo root regeneration(DNRR).However,the comprehensive transcriptional framework of DNRR remains elusive.Here,we provide a high-resolution landscape of transcriptome reprogramming from wound response to root organogenesis in DNRR and show key factors involved in DNRR.Time-lapse RNA sequencing(RNA-seq)of the entire leaf within 12 h of leaf detachment revealed rapid activation of jasmonate,ethylene,and reactive oxygen species(ROS)pathways in response towounding.Genetic analyses confirmed that ethylene andROSmay serve as wound signals to promoteDNRR.Next,time-lapse RNA-seq within 5 d of leaf detachment revealed the activation of genes involved in organogenesis,wound-induced regeneration,and resource allocation in the wounded region of detached leaves during adventitious rooting.Genetic studies showed that BLADE-ON-PETIOLE1/2,which control aboveground organs,PLETHORA3/5/7,which control root organogenesis,and ETHYLENE RESPONSE FACTOR115,which controlswound-induced regeneration,are involved in DNRR.Furthermore,single-cell RNA-seq data revealed gene expression patterns in thewounded region of detached leaves during adventitious rooting.Overall,our study not only provides transcriptome tools but also reveals key factors involved in DNRR from detached Arabidopsis leaves.Wu Liu Yuyun Zhang Xing Fang Sorrel Tran Ning Zhai Zhengfei Yang Fu Guo Lyuqin Chen Jie Yu Madalene SIson Teng Zhang Lijun Sun Hongwu Bian Yijing Zhang Li Yang Lin Xu 2022Plant Communications2022,3,4:0
14Defoliation in Flue-cured Tobacco and Its Reasons显示文摘The flue-cured tobacco G80 is not only one of the characteristic varieties in Changsha,but also indispensable raw materials for the series of Baisha cigarette. Defoliation during the late stage of growth seriously reduces the yield and quality of tobacco,and limits the popularization and application of G80. In this paper,in order to investigate the reasons for the defoliation of G80,the transverse section structure,cellulose content and differential proteins of leaf major veins were analyzed. The results revealed that the autolysis and collapse of parenchyma cells is the main cause of defoliation,and fungal infection is a factor inducing the autolysis of parenchyma cells. Application of bud suppression agent is one of the main ways to prevent fungal infection. The low cellulose content,low synthetic ability of xylan and pectin,the low removal ability of abnormal protein and low immune responsiveness are the inner reason for defoliation of flue-cured tobacco G80.Chungui TANG Fan LI Hongwu YANG Pengfeng CHEN Li LI Jiamei LI Xinjian CHEN Hongxiang GUO Weiqun LIU 2017Agricultural Biotechnology2017,6,3:0
15Investigation of effects of clay content on F-Ф relationship by Lattice gas automation using digital rock model显示文摘The Lattice Gas Automation(LGA) method,which is improved by introducing a reflection coefficient for the border between phases to show its effect on current path,is used in this paper to simulate the current flow in digital rock for investigating the effects of clay content and clay distribution types on the relationship between formation factor(F) and rock porosity(Ф).The digital rock model is constructed by simulating a natural deposit of matrix particles with different shapes and radius.Based on the simulation results,it was found that both dispersed clay and laminated clay can lead to a non-Archie relationship of F-Ф.The non-Archie effect of laminated clay on the F-relationship was more significant than that of dispersed clay.Moreover,a realistic model is developed in this work for quantitatively describing the effect of clay content(Denoted as Vsh) on parameters a and m.These study results have further demonstrated the validity of LGA in study of electrical transport properties at a pore scale.Yue Wenzheng Tao GUo Chai Xiyuan Jiang Hongxiu Mu Hongwu 2011Petroleum Science2011,8,2:0
