| 1 | Identification of a Stable Quantitative Trait Locus for Percentage Grains with White Chalkiness in Rice (Oryza sativa)显示文摘High chalkiness is a major problem in many rice-producing areas of the world, especially in hybrid rice (Oryza sativa L.) in China. We previously showed a major quantitative trait locus for the percentage of grains with white chalkiness (QTLqPGWC-8) in the interval G1149-R727 on chromosome 8 using a chromosome segment substitution line (CSSL). Here, we selected the line-CSSL50 harboring the QTLqPGWC-8 allele from the CSSLs derived from a cross between Asominori (as a recurrent parent) and IR24 (as a donor parent), which had higher percentage chalkiness, markedly different from that of Asominori. There were also significant differences in starch granules, appearance of amylose content (AAC) and milling qualities between Asominori and CSSL50, but not in grain size or thousand grain weight (TGW). The BC4F2 and BC4F3 populations from a cross between CSSL50 and Asominori were used for fine mapping of qPGWC-8. We narrowed down the location of this QTL to a 142 kb region between Indel markers 8G-7 and 8G-9. QTLqPGWC-8 accounted for 50.9% of the difference in PGWC between the parents. The markers tightly linked to qPGWC-8 should facilitate cloning of the gene underlying this QTL and will be of value for marker-assisted selection in breeding rice varieties with better grain quality. | Tao Guo Xiaolu Liu Xiangyuan Wan Jianfeng Weng Shijia Liu Xi Liu Mingjiang Chen Jingjing Li Ning Su Fuqing Wu Zhijun Cheng Xiuping Guo Cailin Lei Jiulin Wang Ling jiang Jianmin Wan | 2011 | Journal of Integrative Plant Biology2011，53，8： | 25 |
| 2 | Maize Genic Male-Sterility Genes and Their Applications in Hybrid Breeding: Progress and Perspectives显示文摘As one of the most important crops, maize not only has been a source of the food, feed, and industrial feedstock for biofuel and bioproducts, but also became a model plant system for addressing fundamental questions in genetics. Male sterility is a very useful trait for hybrid vigor utilization and hybrid seed production. The identification and characterization of genic male-sterility (GMS) genes in maize and other plants have deepened our understanding of the molecular mechanisms controlling anther and pollen development, and enabled the development and efficient use of many biotechnology-based male-sterility (BMS) systems for crop hybrid breeding. In this review, we summarize main advances on the identification and characterization of GMS genes in maize, and con struct a putative regulatory network controlling maize anther and pollen development by comparative genomic analysis of GMS genes in maize, Arabidopsis, and rice. Furthermore, we discuss and appraise the features of more than a dozen BMS systems for propagating male-sterile lines and producing hybrid seeds in maize and other plants. Finally, we provide our perspectives on the studies of GMS genes and the development of novel BMS systems in maize and other plants. The continuous exploration of GMS genes and BMS systems will enhance our understanding of molecular regulatory networks controlling male fertility and greatly facilitate hybrid vigor utilization in breeding and field production of maize and other crops. | Xiangyuan Wan Suowei Wu Ziwen Li Zhenying Dong Xueli An Biao Ma Youhui Tian Jinping Li | 2019 | Molecular Plant2019，12，3： | 24 |

| 4 | ZmMs30 Encoding a Novel GDSL Lipase Is Essential for Male Fertility and Valuable for Hybrid Breeding in Maize显示文摘Genic male sterility (GMS) is very useful for hybrid vigor utilization and hybrid seed production. Although a large number of GMS genes have been identified in plants, little is known about the roles of GDSL lipase members in anther and pollen development. Here, we report a maize GMS gene, ZmMs30, which encodes a novel type of GDSL lipase with diverged catalytic residues. Enzyme kinetics and activity assays show that ZmMs30 has lipase activity and prefers to substrates with a short carbon chain. ZmMs30 is specifically expressed in maize anthers during stages 7-9. Loss of ZmMs30 function resulted in defective anther cuticle, irregular foot layer of pollen exine, and complete male sterility. Cytological and lipidomics analyses demonstrate that ZmMs30 is crucial for the aliphatic metabolic pathway required for pollen exine formation and anther cuticle development. Furthermore, we found that male sterility caused by loss of ZmMs30 function was stable in various inbred lines with different genetic background, and that it didn't show any negative effect on maize heterosis and production, suggesting that ZmMs30 is valuable for crossbreeding and hybrid seed production. We then developed a new multi-control sterility system using ZmMs30 and its mutant line, and demonstrated it is feasible for generating desirable GMS lines and valu. able for hybrid maize seed production. Taken together, our study sheds new light on the mechanisms of anther and pollen development, and provides a valuable male-sterility system for hybrid breeding maize. | Xueli An Zhenying Dong Youhui Tian Ke Xie Suowei Wu Taotao Zhu Danfeng Zhang Van Zhou Canfang Niu Biao Ma Quancan Hou Jianxi Bao Simiao Zhang Ziwen Li Yanbo Wang Tingwei Yan Xiaojing Sun Yuwen Zhang Jinping Li Xiangyuan Wan | 2019 | Molecular Plant2019，12，3： | 15 |
| 5 | Lipid Metabolism: Critical Roles in Male Fertility and Other Aspects of Reproductive Development in Plants显示文摘Fatty acids and their derivatives are essential building blocks for anther cuticle and pollen wall formation.Disruption of lipid metabolism during anther and pollen development often leads to genic male sterility(GMS).To date,many lipid metabolism-related GMS genes that are involved in the formation of anther cuticle,pollen wall,and subcellular organelle membranes in anther wall layers have been identified and characterized.In this review,we summarize recent progress on characterizing lipid metabolism-related genes and their roles in male fertility and other aspects of reproductive development in plants.On the basis of cloned GMS genes controlling biosynthesis and transport of anther cutin,wax,sporopollenin,and tryphine\r\Arabidopsis,rice,and maize as well as other plant species,updated lipid metabolic networks underlying anther cuticle development and pollen wall formation were proposed.Through bioinformatics analysis of anther RNA-sequencing datasets from three maize inbred lines(Oh43,W23,and B73),a total of 125 novel lipid metabolism-related genes putatively involved in male fertility in maize were deduced.More,we discuss the pathways regulating lipid metabolism-related GMS genes at the transcriptional and post-transcriptional levels.Finally,we highlight recent findings on lipid metabolism-related genes and their roles in other aspects of plant reproductive development.A comprehensive understanding of lipid metabolism,genes involved,and their roles in plant reproductive development will facilitate the application of lipid metabolism-related genes in gene editing,haploid and callus induction,molecular breeding and hybrid seed production in crops. | Xiangyuan Wan Suowei Wu Ziwen Li Xueli An Youhui Tian | 2020 | Molecular Plant2020，13，7： | 15 |
| 6 | Normal Structure and Function of Endothecium Chloroplasts Maintained by ZmMs33-Mediated Lipid Biosynthesis in Tapetal Cells Are Critical for Anther Development in Maize显示文摘Genic male sterility(GMS)is critical for heterosis utilization and hybrid seed production.Although GMS mutants and genes have been studied extensively in plants,it has remained unclear whether chloroplast-associated photosynthetic and metabolic activities are involved in the regulation of anther development.In this study,we characterized the function of ZmMs33/ZmGPAT6,which encodes a member of the glycerol-3-phosphate acyltransferase(GPAT)family that catalyzes the first step of the glycerolipid synthetic pathway.We found that normal structure and function of endothecium(En)chloroplasts maintained by ZmMs33-mediated lipid biosynthesis in tapetal cells are crucial for maize anther development.ZmMs33 is expressed mainly in the tapetum at early anther developmental stages and critical for cell proliferation and expansion at late stages.Chloroplasts in En cells of wild-type anthers function as starch storage sites before stage 10 but as photosynthetic factories since stage 10 to enable starch metabolism and carbohydrate supply.Loss of ZmMs33 function inhibits the biosynthesis of glycolipids and phospholipids,which are major components of En chloroplast membranes,and disrupts the development and function of En chloroplasts,resulting in the formation of abnormal En chloroplasts containing numerous starch granules.Further analyses reveal that starch synthesis during the day and starch degradation at night are greatly suppressed in the mutant anthers,leading to carbon starvation and low energy status,as evidenced by low trehalose-6-phosphate content and a reduced ATP/AMP ratio.The energy sensor and inducer of autophagy,SnRK1,was activated to induce early and excessive autophagy,premature PCD,and metabolic reprogramming in tapetal cells,finally arresting the elongation and development of mutant anthers.Taken together,our results not only show that ZmMs33 is required for normal structure and function of En chloroplasts but also reveal that starch metabolism and photosynthetic activities of En chloroplasts at different developmental stages are essential for normal anther development.These findings provide novel insights for understanding how lipid biosynthesis in the tapetum,the structure and function of En chloroplasts,and energy and substance metabolism are coordinated to maintain maize anther development. | Taotao Zhu Ziwen Li Xueli An Yan Long Xiaofeng Xue Ke Xie Biao Ma Danfeng Zhang Yijian Guan Canfang Niu Zhenying Dong Quancan Hou Lina Zhao Suowei Wu Jinping Li Weiwei Jin Xiangyuan Wan | 2020 | Molecular Plant2020，13，11： | 9 |
| 7 | Epigenetics in the pathogenesis of diabetic nephropathy显示文摘Diabetic nephropathy(DN),which is a common microvascular complication with a high incidence in diabetic patients,greatly increases the mortality of patients.With further study on DN,it is found that epigenetics plays a crucial role in the pathophysiological process of DN.Epigenetics has an important impact on the development of DN through a variety of mechanisms,and promotes the generation and maintenance of metabolic memory,thus ultimately leading to a poor prognosis.In this review we discuss the methylation of DNA,modification of histone,and regulation of non-coding RNA involved in the progress of cell dysfunction,inflammation and fibrosis in the kidney,which ultimately lead to the deterioration of DN. | Xue Li Lihong Lu Wenting Hou Ting Huang Xiangyuan Chen Jie Qi Yanjun Zhao Minmin Zhu | 2022 | Acta Biochimica et Biophysica Sinica2022，54，2： | 6 |
| 8 | Comparative study on corrosion resistance and lubrication function of lithium complex grease and polyurea grease显示文摘In this study,lithium complex grease(LCG)and polyurea grease(PUG)were synthesized using mineral oil(500 SN)and polyalphaolefin(PAO40)as base oil,adsorbed onto lithium complex soap and polyurea as thickeners,respectively.The effects of grease formulation(thickener and base oil with different amounts(80,85,and 90 wt%)on the corrosion resistance and lubrication function were investigated in detail.The results have verified that the as-prepared greases have good anti-corrosion ability,ascribed to good salt-spray resistance and sealing function.Furthermore,the increase in the amount of base oil reduces the friction of the contact interface to some extent,whereas the wear resistance of these greases is not consistent with the friction reduction,because the thickener has a significant influence on the tribological property of greases,especially load-carrying capacity.PUG displays better physicochemical performance and lubrication function than LCG under the same conditions,mainly depending on the component/structure of polyurea thickener.The polyurea grease with 90 wt%PAO displays the best wear resistance owing to the synergistic lubrication of grease-film and tribochemical film,composed of Fe_(2)O_(3),FeO(OH),and nitrogen oxide. | Guanlin REN Pengfei ZHANG Xiangyuan YE Wen LI Xiaoqiang FAN Minhao ZHU | 2021 | Friction2021，9，1： | 5 |
| 9 | Breeding with dominant genic male-sterility genes to boost crop grain yield in the post-heterosis utilization era显示文摘APPLICABLE CROP DGMS TECHNOLOGY IN THE POST-HETEROSIS UTILIZATION ERA,The global population is predicted to grow by 25%and reach 10 billion by the mid-21st century(Hickey et al.,2019).To meet the food demands of the growing population with limited agricultural land and fresh water resources,greater and more consistent crop production under fluctuating climate conditions,including various environmental stresses,must be achieved by reducing resource inputs and minimizing environmental impacts(Bailey-Serres et al.t 2019).Thanks to the extensive use of semi-dwarf Green Revolution varieties and single-cross hybrids of major crops(e.g.,rice and maize),grain yield has increased steeply over the past 60 years(Figure 1A and 1B).For example。 | Xiangyuan Wan Suowei Wu Xiang Li | 2021 | Molecular Plant2021，14，4： | 4 |
| 10 | Feasibility analysis of the angular momentum reversal trajectory via hodograph method for high performance solar sails显示文摘In this paper a new phase space of hodograph method is adopted to investigate and better understand the two-dimensional angular momentum reversal(H-reversal) trajectories for high performance solar sails within a fixed cone angle.As the hodograph method and the H-reversal trajectory are not very common,both of them are briefly introduced.The relationship between them are constructed and addressed with a sample trajectory.How the phase space varies according to the sail quality and the fixed sail cone angle is also studied.Through variation of the phase space,the minimum sail lightness number can be obtained by solving a set of algebraic equations instead of a parameter optimization problem.For a given sail lightness number,there are three types of the two-dimensional possible heliocentric motion,including the spiral inward trajectories towards the Sun,the H-reversal trajectories and the directly outward escape trajectories.The boundaries that separate these different groups are easily determined by using the phase space.Finally,the method and procedures to achieve the feasible region of the H-reversal trajectory with required perihelion distance are presented in detail. | ZENG XiangYuan BAOYIN HeXi LI JunFeng GONG ShengPing | 2011 | Science China(Technological Sciences)2011，54，11： | 3 |
| 11 | Generalized flyby trajectories around elongated minor celestial bodies as a rotating mass dipole显示文摘The aim of this paper is to understand the common characteristics of the generalized flyby trajectory around natural elongated bodies. Such flyby trajectories provide a short-term mechanism to clear away vicinal objects or temporally capture ejecta into circling orbits. The gravitational potential of elongated bodies is described by a unified approximate model, i.e., the rotating mass dipole which is two point masses connected with a constant massless rod The energy power is used to illustrate the flyby effect in terms of the instantaneous orbital energy. The essential of the single flyby trajectory is studied analytically, and the relationship between the flyby trajectory and its Jacobi integral is also illustrated. Sample trajectories are given to show the variational trend of the energy increment with respect to differen orbital periapsides. The distribution of natural ejecting orbits is presented by varying the parameters of the approximate model. | Xiangyuan Zeng Baodong Fang Junfeng Li Yang Yu | 2016 | Acta Mechanica Sinica2016，32，3： | 3 |
| 12 | The essential roles of sugar metabolism for pollen development and male fertility in plants显示文摘Sugar metabolism plays an essential role in plant male reproduction. Defects in sugar metabolism during anther and pollen development often result in genic male sterility(GMS). In this review, we summarize the recent progresses of the sugar metabolism-related GMS genes and their roles during plant anther and pollen development, including callose wall and primexine formation, intine development, pollen maturation and starch accumulation, anther dehiscence, and pollen germination and tube growth. We predict 112 putative sugar metabolic GMS genes in maize based on bioinformatics and RNA-seq analyses, and most of them have peak expression patterns during middle or late anther developmental stages.Finally, we outline the potential applications of sugar metabolic GMS genes in crop hybrid breeding and seed production. This review will deepen our understanding on sugar metabolic pathways in controlling pollen development and male fertility in plants. | Shuangshuang Liu Ziwen Li Suowei Wu Xiangyuan Wan | 2021 | The Crop Journal2021，9，6： | 2 |
| 13 | Genome-wide analyses on transcription factors and their potential microRNA regulators involved in maize male fertility显示文摘Anther development is a programmed biological process crucial to plant male reproduction. Genomewide analyses on the functions of transcriptional factor(TF) genes and their microRNA(miRNA) regulators contributing to anther development have not been comprehensively performed in maize. Here, using published RNA-Seq and small RNA-Seq(sRNA-Seq) data from maize anthers at ten developmental stages in three genic male-sterility(GMS) mutants(ocl4, mac1, and ms23) and wild type W23, as well as newly sequenced maize anther transcriptomes of ms7-6007 and lob30 GMS mutants and their WT lines, we analyzed and found 1079 stage-differentially expressed(stage-DE) TF genes that can be grouped into six(premeiotic, meiotic, postmeiotic, premeiotic-meiotic, premeiotic-postmeiotic, and meiotic-postmeiotic clusters) expression clusters. Functional enrichment combined with cytological and physiological analyses revealed specific functions of genes in each expression cluster. In addition, 118 stage-DE miRNAs and99 miRNA-TF gene pairs were identified in maize anthers. Further analyses revealed the regulatory roles of zma-miR319 and zma-miR159 as well as ZmMs7 and ZmLOB30 on ZmGAMYB expression. Moreover,ZmGAMYB and its paralog ZmGAMYB-2 were demonstrated as novel maize GMS genes by CRISPR/Cas9 knockout analysis. These results extend our understanding on the functions of miRNA-TF gene regulatory pairs and GMS TF genes contributing to male fertility in plants. | Ziwen Li Taotao Zhu Shuangshuang Liu Yilin Jiang Haoyun Liu Yuwen Zhang Ke Xie Jinping Li Xueli An Xiangyuan Wan | 2021 | The Crop Journal2021，9，6： | 2 |

| 15 | Explicit solvent model for spectral shift of acrolein and simulation with molecular dynamics显示文摘By introducing the concept of spring energy of permanent dipole and taking the conforma-tions of solvent molecules into account,the formulas of electrostatic solvation energy in equilibrium and nonequilibrium are derived from the explicit solvent scheme,with the spatial distribution of the discrete permanent charges and induced dipoles of the sol-vent molecules involved. The energy change of sol-ute due to the variation of wave function from the case of vacuum to that in solution is estimated by treating the solvent effect as external field in the it-eration cycles of the self-consistent field. The ex-pression for spectral shift is deduced and applied to the processes of light absorption and emission in solution. According to the new formulations,the av-eraged solvent electrostatic potential/molecular dy-namics program is modified and adopted to investi-gate the equilibrium solvation energy of water mole-cule and spectral shift of acrolein. | ZHU Quan LIU Jifeng FU Kexiang HAN Keli LI Xiangyuan | 2006 | Chinese Science Bulletin2006，51，24： | 1 |
| 16 | One approach to calculating the solvent reorganization energy of intramolecular electron transfer显示文摘On the basis of the electromagnetic field theory and the spherical cavity approximation, the expressions ofGibbs free energies under equilibrium and non-equilibrium solvation conditions are obtained by solving the electrostatic potential equations with boundary conditions. The surface charges produced by the orientational polarization of equi-librium solvation are taken fixed in the case of non-equilibrium situation, for the slow-response of the orientational polarization to electron transfer of the solvent molecules. Anew expression of solvent reorganization energy has beenobtained and this method is applied to the electron transfer systems, NO+/NO, NO2+/NO2, and NO2+/NO. The solvent reorganization energies have been evaluated. | FU Kexiang1,2, LI Xiangyuan1, ZHU Quan1 & LU Shenzhuang1 1. College of Chemical Engineering, Sichuan University, Chengdu 610065, China 2.

| 17 | Thermodynamics for nonequilibrium solvation and numerical evaluation of solvent reorganization energy显示文摘This work presents a thermodynamic method for treating nonequilibrium solvation. By imposing an extra electric field onto the nonequilibrium solvation system, a virtual constrained equilibrium state is prepared. In this way, the free energy difference between the real nonequilibrium state and the con-strained equilibrium one is simply the potential energy of the nonequilibrium polarization in the extra electronic field, according to thermodynamics. Further, new expressions of nonequilibrium solvation energy and solvent reorganization energy have been formulated. Analysis shows that the present formulations will give a value of reorganization energy about one half of the traditional Marcus theory in polar solvents, thus the explanation on why the traditional theory tends to overestimate this quantity has been found out. For the purpose of numerical determination of solvent reorganization energy, we have modified Gamess program on the basis of dielectric polarizable continuum model. Applying the procedure to the well-investigated intramolecular electron transfer in biphenyl-androstane-naphthyl and biphenyl-androstane-phenanthryl systems, the numerical results of solvent reorganization energy have been found to be in good agreement with the experimental fittings. | LI XiangYuan WANG JingBo MA JianYi FU KeXiang HE FuCheng | 2008 | Science China Chemistry2008，51，12： | 1 |
