1GS6, A Member of the GRAS Gene Family,Negatively Regulates Grain Size in Rice显示文摘Grain size is an important yield related trait in rice.Intensive arti cial selection for grain size during domestication is evidenced by the larger grains of most of today’s cultivars compared with their wild relatives.However,the molecular genetic control of rice grain size is still not well characterized.Here,we report the identi cation and cloning of Grain Size 6(GS6),which plays an important role in reducing grain size in rice.A premature stop at the t348 position in the coding sequence(CDS)of GS6 increased grain width and weight signi cantly.Alignment of the CDS regions of GS6 in 90 rice materials revealed three GS6alleles.Most japonica varieties(95%)harbor the Type I haplotype,and 62.9%of indica varieties harbor the Type II haplotype.Association analysis revealed that the Type I haplotype tends to increase the width and weight of grains more than either of the Type II or Type III haplotypes.Further investigation of genetic diversity and the evolutionary mechanisms of GS6showed that the GS6gene was strongly selected in japonica cultivars.In addition,a'ggc'repeat region identi ed in the region that encodes the GRAS domain of GS6 played an important historic role in the domestication of grain size in rice.Knowledge of the function of GS6might aid efforts to elucidate the molecular mechanisms that control grain development and evolution in rice plants,and could facilitate the genetic improvement of rice yield.Lianjun Sun Xiaojiao Li Yongcai Fu Zuofeng Zhu Lubin Tan Fengxia Liu Xianyou Sun Xuewen Sun Chuanqing Sun 2013Journal of Integrative Plant Biology2013,55,10:44

3LHD1,an Allele of DTH8/Ghd8,Controls Late Heading Date in Common Wild Rice (Oryza rufipogon)显示文摘Flowering at suitable time is very important for plants to adapt to complicated environments and produce their seeds successfully for reproduction.In rice (Oryza rufipogon Griff.) photoperiod regulation is one of the important factors for controlling heading date.Common wild rice,the ancestor of cultivated rice,exhibits a late heading date and a more sensitive photoperiodic response than cultivated rice.Here,through map-based cloning,we identified a major quantitative trait loci (QTL) LHD1 (Late Heading Date 1),an allele of DTH8/Ghd8,which controls the late heading date of wild rice and encodes a putative HAP3/NF-YB/CBF-A subunit of the CCAAT-box-binding transcription factor.Sequence analysis revealed that several variants in the coding region of LHD1 were correlated with a late heading date,and a further complementary study successfully rescued the phenotype.These results suggest that a functional site for LHD1 could be among those variants present in the coding region.We also found that LHD1 could down-regulate the expression of several floral transition activators such as Ehd1,Hd3a and RFT1 under long-day conditions,but not under short-day conditions.This indicates that LHD1 may delay flowering by repressing the expression of Ehd1,Hd3a and RFT1 under long-day conditions.Xiaodong Dai Younian Ding Lubin Tan Yongcai Fu Fengxia Liu Zuofeng Zhu Xianyou Sun Xuewen Sun Ping Gu Hongwei Cai Chuanqing Sun 2012Journal of Integrative Plant Biology2012,54,10:23
4NARROW AND ROLLED LEAF 2 regulates leaf shape,male fertility, and seed size in rice显示文摘Grain yield in rice(Oryza sativa L.) is closely related to leaf and flower development. Coordinative regulation of leaf, pollen, and seed development in rice as a critical biological and agricultural question should be addressed. Here we identified two allelic rice mutants with narrow and semirolled leaves, named narrow and rolled leaf 2-1(nrl2-1) and nrl2-2. Map-based molecular cloning revealed that NRL2 encodes a novel protein with unknown biochemical function. The mutation of NRL2 caused pleiotropic effects, including a reduction in the number of longitudinal veins, defective abaxial sclerenchymatous cell differentiation, abnormal tapetum degeneration and microspore development, and the formation of more slender seeds compared with the wild type(WT). The NRL2 protein interacted with Rolling-leaf(RL14),causing the leaves of the nrl2 mutants to have a highercellulose content and lower lignin content than the WT, which may have been related to sclerenchymatous cell differentiation and tapetum degeneration. Thus, this gene is an essential developmental regulator controlling fundamental cellular and developmental processes, serving as a potential breeding target for high-yielding rice cultivars.Shuangshuang Zhao Lei Zhao Fengxia Liu Yongzhen Wu Zuofeng Zhu Chuanqing Sun Lubin Tan 2016Journal of Integrative Plant Biology2016,58,12:19

6Natural Variations at TIG1 Encoding a TCP Tran scription Factor Contribute to Plant Architecture Domestication in Rice显示文摘The modification of plant architecture is a crucial target in rice domestication and modern genetic improvement.Although several genes regulating rice plant architecture have been characterized,the molecular mechanisms underlying rice plant architecture domestication remain largely unclear.Here we show that the inclined tiller growth in wild rice is controlled by a single dominant gene,TILLER INCLINED GROWTH 1 (T/Gf),which is located on chromosome 8 and encodes a TCP transcriptional activator.TIG1 is primarily expressed in the adaxial side of the tiller base,promotes cell elongation,and enlarges the tiller angle in wild rice.Variations in the TIG1 promoter of indica cultivars {tig1 allele) resulted in decreased expression of TIG1 in the adaxial side of tiller base and reduced cell length and tiller angle,leading to the transition from inclined tiller growth in wild rice to erect tiller growth during rice domestication.TIG1 positively regulates the expression of EXP A3,EXPB5,and SAUR39 to promote cell elongation and increase the tiller angle.Selective sweep analysis revealed that the tig1 allele was selected in indica cultivars by human beings.The cloning and characterization of TIG1 supports a new scenario of plant architecture evolution in rice.Weifeng Zhang Lubin Tan Hongying Sun Xinhui Zhao Fengxia Liu Hongwei Cai Yongcai Fu Xianyou Sun Ping Gu Zuofeng Zhu Chuanqing Sun 2019Molecular Plant2019,12,8:13

8Influencing factors of water resources in the source region of the Yellow River显示文摘Taking the source region of the Yellow River as a study area and based on the data from Madoi Meteorological Station and Huangheyan Hydrological Station covering the period 1955–2005, this paper analyses the changing trends of surface water resources, climate and frozen ground and reveals their causes. Results show that there exist frequent fluctuations from high to low water flow in the 51-year period. In general, the discharge has shown a de- clining trend in the 51 years especially since the 1990s. The annual distribution shows one peak which, year on year is getting smaller. (1) Precipitation has a significant and sustained influence on discharge. (2) A sharp rise of temperature resulted in the increase of evaporation and the decrease of discharge, which has a greater effect than on ice-snow melting. (3) Frozen ground tends to be degraded markedly. There is a significant positive correlation be- tween the permafrost thickness and the discharge. (4) Evaporation rates are significantly increasing, leading to the decrease of discharge. 70% of the discharge reduction resulted from climate change, and the remaining 30% may have been caused by human activities.CHANG Guogang LI Lin ZHU Xide WANG Zhenyu XIAO Jianshe LI Fengxia 2007Journal of Geographical Sciences2007,17,2:7
9Histological, hormonal and transcriptomic reveal the changes upon gibberellin-induced parthenocarpy in pear fruit显示文摘Phytohormones play crucial roles in fruit set regulation and development.Here,gibberellins(GA4+7),but not GA3,induced pear parthenocarpy.To systematically investigate the changes upon GA4+7 induced pear parthenocarpy,dynamic changes in histology,hormone and transcript levels were observed and identified in unpollinated,pollinated and GA4+7-treated ovaries.Mesocarp cells continued developing in both GA4+7-treated and pollinated ovaries.In unpollinated ovaries,mesocarp cells stopped developing 14 days after anthesis.During fruit set process,GA4+7,but not GA1+3,increased after pollination.Abscisic acid(ABA)accumulation was significantly repressed by GA4+7 or pollination,but under unpollinated conditions,ABA was produced in large quantities.Moreover,indole-3-acetic acid biosynthesis was not induced by GA4+7 or pollination treatments.Details of this GA–auxin–ABA cross-linked gene network were determined by a comparative transcriptome analysis.The indole-3-acetic acid transport-related genes,mainly auxin efflux carrier component genes,were induced in both GA4+7-treated and pollinated ovaries.ABA biosynthetic genes of the 9-cis-epoxycarotenoid dioxygenase family were repressed by GA4+7 and pollination.Moreover,directly related genes in the downstream parthenocarpy network involved in cell division and expansion(upregulated),and MADS-box family genes(downregulated),were also identified.Thus,a model of GA-induced hormonal balance and its effects on parthenocarpy were established.Lulu Liu Zhigang Wang Jianlong Liu Fengxia Liu Rui Zhai Chunqin Zhu Huibin Wang Fengwang Ma Lingfei Xu 2018Horticulture Research2018,5,1:7
10Biodegradation of organochlorine pesticide endosulfan by bacterial strain Alcaligenes faecalis JBW4显示文摘The recently discovered endosulfan-degrading bacterial strain Alcaligenes faecalis JBW4 was isolated from activated sludge. This strain is able to use endosulfan as a carbon and energy source. The optimal conditions for the growth of strain JBW4 and for biodegradation by this strain were identified, and the metabolic products of endosulfan degradation were studied in detail. The maximum level of endosulfan biodegradation by strain JBW4 was obtained using broth at an initial pH of 7.0, an incubation temperature of 40°C and an endosulfan concentration of 100 mg/L. The concentration of endosulfan was determined by gas chromatography. Strain JBW4 was able to degrade 87.5% of α-endosulfan and 83.9% of β-endosulfan within 5 days. These degradation rates are much higher than the previously reported bacterial strains. Endosulfan diol and endosulfan lactone were the major metabolites detected by gas chromatography-mass spectrometry; endosulfan sulfate, which is a persistent and toxic metabolite, was not detected. These results suggested that A. faecalis JBW4 degrades endosulfan via a non-oxidative pathway. The biodegradation of endosulfan by A. faecalis is reported for the first time. Additionally, the present study indicates that strain JBW4 may have potential for the biodegradation of endosulfan residues.Lingfen Kong Shaoyuan Zhu Lusheng Zhu Hui Xie Kunchang Su Tongxiang Yan Jun Wang Jinhua Wang Fenghua Wang Fengxia Sun 2013Journal of Environmental Sciences2013,25,11:4
11Epidemiological characteristics and temporal-spatial analysis of overseas imported dengue fever cases in outbreak provinces of China, 2005–2019显示文摘Background Overseas imported dengue fever is an important factor in local outbreaks of this disease in the mainland of China.To better prevent and control such local outbreaks,the epidemiological characteristics and temporal-spatial distribution of overseas imported dengue fever cases in provincial-level administrative divisions(PLADs)where dengue fever is outbreak in the mainland of China were explored.Methods Using the Chinese National Notifiable Infectious Disease Reporting Information System(CNNDS),we identified overseas imported dengue fever cases in dengue fever outbreak areas in the mainland of China from 2005 to 2019 to draw the epidemic curve and population characteristic distribution of overseas imported cases in each PLAD.Based on spatial autocorrelation analysis of ArcGIS 10.5 and temporal-spatial scanning analysis of SaTScan 9.5,we analyzed the temporal-spatial distribution of overseas imported dengue fever in dengue fever outbreak areas in the mainland of China.Results A total of 11,407 imported cases,mainly from Southeast Asia,were recorded from 2005 to 2019 in these 13 PLADs.Of which 62.1%were imported into Yunnan and Guangdong Provinces.Among the imported cases,there were more males than females,mainly from the 21–50 age group.The hot spots were concentrated in parts of Yunnan,Guangdong and Fujian Provinces.We found the cluster of infected areas were expanding northward.Conclusions Based on the analysis of overseas imported dengue cases in 13 PLADs of the mainland of China from 2005 to 2019,we obtained the epidemiological characteristics and spatial distribution of imported dengue cases.Border controls need to pay attention to key population sectors,such as 21–50 years old men and education of key populations on dengue prevention.There is a need to improve the awareness of the prevention and control of imported cases in border areas.At the same time,northern regions cannot relax their vigilance.Xinchang Lun Yiguan Wang Chunchun Zhao Haixia Wu Caiying Zhu Delong Ma Mingfang Xu Jun Wang Qiyong Liu Lei Xu Fengxia Meng 2022Infectious Diseases of Poverty2022,11,1:3
122022 Chinese expert consensus and guidelines on clinical management of toxicity in anti-CD19 chimeric antigen receptor T-cell therapy for B-cell non-Hodgkin lymphoma显示文摘Adoptive cellular immunotherapy with chimeric antigen receptor(CAR)T cells has emerged as a novel modality for treating relapsed and/or refractory B-cell non-Hodgkin lymphoma(B-NHL).With increasing approval of CAR T-cell products and advances in CAR T cell therapy,CAR T cells are expected to be used in a growing number of cases.However,CAR T-cell-associated toxicities can be severe or even fatal,thus compromising the survival benefit from this therapy.Standardizing and studying the clinical management of these toxicities are imperative.In contrast to other hematological malignancies,such as acute lymphoblastic leukemia and multiple myeloma,anti-CD19 CAR T-cell-associated toxicities in B-NHL have several distinctive features,most notably local cytokine-release syndrome(CRS).However,previously published guidelines have provided few specific recommendations for the grading and management of toxicities associated with CAR T-cell treatment for B-NHL.Consequently,we developed this consensus for the prevention,recognition,and management of these toxicities,on the basis of published literature regarding the management of anti-CD19 CAR T-cell-associated toxicities and the clinical experience of multiple Chinese institutions.This consensus refines a grading system and classification of CRS in B-NHL and corresponding measures for CRS management,and delineates comprehensive principles and exploratory recommendations for managing anti-CD19 CAR T-cell-associated toxicities in addition to CRS.Ping Li Yang Liu Yun Liang Jian Bo Sujun Gao Yongxian Hu Yu Hu He Huang Xiaojun Huang Hongmei Jing Xiaoyan Ke Jianyong Li Yuhua Li Qifa Liu Peihua Lu Heng Mei Ting Niu Yongping Song Yuqin Song Liping Su Sanfang Tu Jianxiang Wang Depei Wu Zhao Wang Kailin Xu Zhitao Ying Qingming Yang Yajing Zhang Fengxia Shi Bin Zhang Huilai Zhang Xi Zhang Mingfeng Zhao Weili Zhao Xiangyu Zhao Liang Huang Jun Zhu Wenbin Qian Weidong Han Aibin Liang 2023Cancer Biology & Medicine2023,20,2:3

14Hexagonal boron nitride:A metal-free catalyst for deep oxidative desulfurization of fuel oils显示文摘Oxidative desulfurization(ODS)has been proved to be an efficient strategy for the production of clean fuel oil.Numerous metal-based materials have been employed as excellent ODS catalysts,but being hindered by their high-cost and potential secondary pollution.In this work,we employed graphene analogous hexagonal boron nitride(h-BN)as a metal-free catalyst for ODS with hydrogen peroxide(H2O2)as the oxidant.The h-BN catalyst was characterized and proved to be a few-layered structure with relatively high specific surface areas.The h-BN catalyst showed a 99.4%of sulfur removal in fuel oil under the optimized reaction conditions.Besides,the h-BN can be recycled for 8 times without significant decrease in the catalytic performance.Detailed mechanism analysis found that it is the boron radicals in h-BN activated H2O2 to generate·OH species,which can readily oxidize sulfides to corresponding sulfones for separation.This work would provide another choice in choosing metal-free catalysts for ODS.Peiwen Wu Linjie Lu Jing He Linlin Chen Yanhong Chao Minqiang He Fengxia Zhu Xiaozhong Chu Huaming Li Wenshuai Zhu 2020Green Energy & Environment2020,5,2:3
15Polyamine oxidase 3 is involved in salt tolerance at the germination stage in rice显示文摘Soil salinity inhibits seed germination and reduces seedling survival rate,resulting in significant yield reductions in crops.Here,we report the identification of a polyamine oxidase,OsPAO3,conferring salt tolerance at the germination stage in rice(Oryza sativa L.),through map-based cloning approach.OsPAO3 is up-regulated under salt stress at the germination stage and highly expressed in various organs.Overexpression of OsPAO3 increases activity of polyamine oxidases,enhancing the polyamine content in seed coleoptiles.Increased polyamine may lead to the enhance of the activity of ROS-scavenging enzymes to eliminate over-accumulated H;O;and to reduce Na;content in seed coleoptiles to maintain ion homeostasis and weaken Na;damage.These changes resulted in stronger salt tolerance at the germination stage in rice.Our findings not only provide a unique gene for breeding new salt-tolerant rice cultivars but also help to elucidate the mechanism of salt tolerance in rice.Guangyu Liu Wanxia Jiang Lei Tian Yongcai Fu Lubin Tan Zuofeng Zhu Chuanqing Sun Fengxia Liu 2022Journal of Genetics and Genomics2022,49,5:2
16Feasibility of Intermediate Fluid Vaporizer with Spiral Wound Tubes显示文摘A novel intermediate fluid vaporization (IFV) technology for LNG re-gasification process with spiral-wound heat exchanging tubes is proposed. The new IFV project combines the advantage of running the shell and tube heat exchangers at high pressure with the advantage of compact space of heat exchangers. Thermal analysis on the two processes of forced convection and vaporization type heat transfer in the spiral wound tubes and vapor condensation /re-boiling type of heat transfer via intermediate fluid in shell side shows the feasibility of this promising technology.Liu Fengxia Dai Yuqiang Wei Wei Zou Jiupeng Zhu Che Dong Chao Hu Dapeng 2013China Petroleum Processing & Petrochemical Technology2013,15,1:2
17Macroscopic MXene ribbon with oriented sheet stacking for high‐performance flexible supercapacitors显示文摘Flexible and wearable fiber electrodes with high conductivity and acceptable electrochemical behavior are crucial for extending the application of nextgeneration portable electronics,the development of which,however,is very challenging.Two‐dimensional sheets are known to be excellent units for assembling fiber entities,particularly when sheets are oriented in a stacking manner,which helps integrate their intrinsic in‐plane advantages,especially those related with mechanical and electronic performances.In this study,we developed a flexible macroscopic and continuous fiber in an unusual ribbon shape composed solely of Ti3C2 sheets,a typical member of the MXene family.The ribbon morphology was realized through highly ordered stacking of Ti3C2,which imparts fibers with favorable mechanical characteristics.Based on the intrinsic metallic conductivity of Ti3C2 sheets and the oriented stacking structure,the developed macroscopic ribbon exhibited excellent conductivity for both electrons(up to 2458 S/cm)and ions.A fiber‐shaped asymmetric supercapacitor using the developed macroscopic ribbon as a cathode coupled with reduced graphene oxide fibers as an anode delivered a competitive maximum volumetric energy density of 58.4mWh/cm3(20.0Wh/kg)while maintaining a power level of 1679.0mW/cm3(581.0 W/kg)and excellent cycling stability(92.4%retention after 10000 cycles at 10 A/g).This study highlights the excellent potential of MXene as a platform for macroscopic assembly and definitely broadens the applications of MXene materials in wearable electronics.Chao Zhu Fengxia Geng 2021Carbon Energy2021,3,1:2
18Effect of Friction on Dynamic Response of A Power Split Transmission System显示文摘The tooth surface friction stiffness and friction torque coefficient equations of cylindrical gear are derived.On the basis of factors such as time varying friction coefficient and mesh stiffness,support stiffness,torsional stiffness and comprehensive error,the dynamic equations of the gear trains with bending torsional coupling are established.Using the Fourier series method,the total response of the system is obtained,and the influence of friction on it is analyzed.The results show that when the spur gear enters the meshing,the frictional amplitude of the tooth surface is larger than that of the gear when it is withdrawn from engagement,and the meshing force fluctuates greatly.The frictional force and dynamic meshing force of the herringbone gear tooth surface are relatively stable,and the fluctuation amplitude is much smaller than that of the spur gear.The amplitude of the bearing vibration is not affected by the friction,but the friction has a certain influence on the bearing force of the output shaft.The first order natural frequency of the split stage and the power confluence stage has a large influence on the vibration of the bearing force.In general,the natural frequency of the power confluence stage has a large proportion of influence.JIN Guanghu YANG Haoyun LU Fengxia ZHU Rupeng 2019Transactions of Nanjing University of Aeronautics and Astronautics2019,36,3:1
19Enhanced thermoelectric performance and atomic-resolution interfacial structures in BiSbTe thermo-electro-magnetic nanocomposites incorporating magnetocaloric LaFeSi nanoparticles显示文摘Incorporating magnetic nanoparticles in thermoelectric(TE)materials introduce magnetic interfaces with additional electron and phonon scattering mechanism for high TE performance.However,the influence of heterogeneous interfaces between magnetic nanoparticles and TE matrix on electronic and thermal transport remains elusive in the thermo-electric-magnetic nanocomposites.Here,using p-type TE material Bi_(0.3)Sb_(1.7)Te_(3)(BST)as matrix and magnetocaloric(MC)material La(Fe_(0.92)Co_(0.08))_(11.9)Si_(1.1)(LFS)nanoparticles as a second phase,TE/MC nanocomposites xLFS/BST(x=0.1%,0.2%,0.3% and 0.4%)were synthesized using spark plasma sintering method.The atomic-resolution interfacial structures demonstrate that Te vacancies originating from LFS-BST interfacial reaction decreases the hole concentration of the LFS/BST nanocomposites and enhances the Seebeck coefficient.The LFS/BST nanocomposites exhibit lower thermal conductivity due to enhanced phonon scattering by interfaces and defects.All the nanocomposites have higher ZT than BST matrix,with 0.2% LFS/BST nanocomposite achieving highest ZT=1.11 at 380 K.At working current 1.4 A,the device fabricated using 0.2% LFS/BST nanocomposite achieves maximal cooling temperature 4.9 K,which is 58% higher than the matrix.Moreover,the MC properties are retained in all the nanocomposites,which make them a promising candidate to achieve high TE performance and dual TE/MC properties for future applications.Lin Xing Wenjun Cui Xiahan Sang Fengxia Hu Ping Wei Wanting Zhu Xiaolei Nie Qingjie Zhang Wenyu Zhao 2021Journal of Materiomics2021,7,5:1
