| 1 | Differential responses of short-term soil respiration dynamics to the experimental addition of nitrogen and water in the temperate semi-arid steppe of Inner Mongolia, China显示文摘We examined the effects of simulated rainfall and increasing N supply of different levels on CO2 pulse emission from typical Inner Mongolian steppe soil using the static opaque chamber technique, respectively in a dry June and a rainy August. The treatments included NH4NO3 additions at rates of 0, 5, 10, and 20 g N/(m2·year) with or without water. Immediately after the experimental simulated rainfall events, the CO2 effluxes in the watering plots without N addition(WCK) increased greatly and reached the maximum value at 2 hr. However, the efflux level reverted to the background level within 48 hr. The cumulative CO2 effluxes in the soil ranged from 5.60 to 6.49 g C/m2over 48 hr after a single water application, thus showing an increase of approximately 148.64% and 48.36% in the effluxes during both observation periods. By contrast, the addition of different N levels without water addition did not result in a significant change in soil respiration in the short term. Two-way ANOVA showed that the effects of the interaction between water and N addition were insignificant in short-term soil CO2 effluxes in the soil. The cumulative soil CO2fluxes of different treatments over 48 hr accounted for approximately 5.34% to 6.91% and 2.36% to 2.93% of annual C emission in both experimental periods. These results stress the need for improving the sampling frequency after rainfall in future studies to ensure more accurate evaluation of the grassland C emission contribution. | Yuchun Qi Xinchao Liu Yunshe Dong Qin Peng Yating He Liangjie Sun Junqiang Jia Congcong Cao | 2014 | Journal of Environmental Sciences2014，26，4： | 17 |
| 2 | Litter decomposition and C and N dynamics as affected by N additions in a semi-arid temperate steppe, Inner Mongolia of China显示文摘Litter decomposition is the fundamental process in nutrient cycling and soil carbon(C) sequestration in terrestrial ecosystems. The global-wide increase in nitrogen(N) inputs is expected to alter litter decomposition and,ultimately, affect ecosystem C storage and nutrient status. Temperate grassland ecosystems in China are usually N-deficient and particularly sensitive to the changes in exogenous N additions. In this paper, we conducted a 1,200-day in situ experiment in a typical semi-arid temperate steppe in Inner Mongolia to investigate the litter decomposition as well as the dynamics of litter C and N concentrations under three N addition levels(low N with 50 kg N/(hm2?a)(LN), medium N with 100 kg N/(hm2?a)(MN), and high N with 200 kg N/(hm2?a)(HN)) and three N addition forms(ammonium-N-based with 100 kg N/(hm2?a) as ammonium sulfate(AS), nitrate-N-based with 100 kg N/(hm2?a) as sodium nitrate(SN), and mixed-N-based with 100 kg N/(hm2?a) as calcium ammonium nitrate(CAN)) compared to control with no N addition(CK). The results indicated that the litter mass remaining in all N treatments exhibited a similar decomposition pattern: fast decomposition within the initial 120 days, followed by a relatively slow decomposition in the remaining observation period(120–1,200 days). The decomposition pattern in each treatment was fitted well in two split-phase models, namely, a single exponential decay model in phase I(<398 days) and a linear decay function in phase II(≥398 days). The three N addition levels exerted insignificant effects on litter decomposition in the early stages(<398 days, phase I; P>0.05). However, MN and HN treatments inhibited litter mass loss after 398 and 746 days, respectively(P<0.05). AS and SN treatments exerted similar effects on litter mass remaining during the entire decomposition period(P>0.05). The effects of these two N addition forms differed greatly from those of CAN after 746 and 1,053 days, respectively(P<0.05). During the decomposition period, N concentrations in the decomposing litter increased whereas C concentrations decreased, which also led to an exponential decrease in litter C:N ratios in all treatments. No significant effects were induced by N addition levels and forms on litter C and N concentrations(P>0.05). Our results indicated that exogenous N additions could exhibit neutral or inhibitory effects on litter decomposition, and the inhibitory effects of N additions on litter decomposition in the final decay stages are not caused by the changes in the chemical qualities of the litter, such as endogenous N and C concentrations. These results will provide an important data basis for the simulation and prediction of C cycle processes in future N-deposition scenarios. | Qin PENG YuChun QI YunShe DONG YaTing HE ShengSheng XIAO XinChao LIU LiangJie SUN JunQiang JIA ShuFang GUO CongCong CAO | 2014 | Journal of Arid Land2014，6，4： | 16 |
| 3 | Co-Co304@carbon core-shells derived from metal-organic framework nanocrystals as efficient hydrogenevolution catalysts显示文摘Controllable pyrolysis of metal-organic frameworks (MOFs) in confined spacesis a promising strategy for the design and development of advanced functionalmaterials. In this study, Co-C0304@carbon composites were synthesized viapyrolysis of a Co-MOFs@glucose polymer (Co-MOFs@GP) followed by partialoxidation of Co nanoparticles (NPs). The pyrolysis of Co-MOFs@GP generated acore-shell structure composed of carbon shells and Co NPs. The controlled partialoxidation of Co NPs formed Co-Co304 heterojunctions confined in carbon shells.Compared with Co-MOFs@GP and Co@carbon-n (Co@C-n), Co-C0304@carbon-n(Co-Co304@C-n) exhibited higher catalytic activity during NaBH4 hydrolysis.Co-C0304@C-II provided a maximum specific H2 generation rate of5,360 mL.min-l.gco-1 at room temperature due to synergistic interactionsbetween Co and C0304 NPs. The Co NPs also endowed Co-C0304@C-n with theferromagnetism needed to complete the magnetic momentum transfer process. | Yanyan Liu Guosheng Han Xiaoyu Zhang Congcong Xing Chenxia Du Huaqiang Cao Baojun Li | 2017 | Nano Research2017，10，9： | 5 |
| 4 | Maneuvering target tracking algorithm based on cubature Kalman filter with observation iterated update显示文摘Reasonable selection and optimization of a filter used in model estimation for a multiple model structure is the key to improve tracking accuracy of maneuvering target.Combining with the cubature Kalman filter with iterated observation update and the interacting multiple model method,a novel interacting multiple model algorithm based on the cubature Kalman filter with observation iterated update is proposed.Firstly,aiming to the structural features of cubature Kalman filter,the cubature Kalman filter with observation iterated update is constructed by the mechanism of iterated observation update.Secondly,the improved cubature Kalman filter is used as the model filter of interacting multiple model,and the stability and reliability of model identification and state estimation are effectively promoted by the optimization of model filtering step.In the simulations,compared with classic improved interacting multiple model algorithms,the theoretical analysis and experimental results show the feasibility and validity of the proposed algorithm. | 胡振涛 Fu Chunling Cao Zhiwei Li Congcong | 2015 | High Technology Letters2015，21，1： | 4 |
| 5 | Response of soil N_2O emissions to precipitation pulses under different nitrogen availabilities in a semiarid temperate steppe of Inner Mongolia, China显示文摘Short-term nitrous oxide(N2O) pulse emissions caused by precipitation account for a considerable portion of the annual N2O emissions and are greatly influenced by soil nitrogen(N) dynamics. However, in Chinese semiarid temperate steppes, the response of N2O emissions to the coupling changes of precipitation and soil N availability is not yet fully understood. In this study, we conducted two 7-day field experiments in a semiarid temperate typical steppe of Inner Mongolia, China, to investigate the N2O emission pulses resulting from artificial precipitation events(approximately equivalent to 10.0 mm rainfall) under four N addition levels(0, 5, 10 and 20 g N/(m2·a)) using the static opaque chamber technique. The results show that the simulated rainfall during the dry period in 2010 caused greater short-term emission bursts than that during the relatively rainy observation period in 2011(P<0.05). No significant increase was observed for either the N2O peak effluxes or the weekly cumulative emissions(P>0.05) with single water addition. The peak values of N2O efflux increased with the increasing N input. Only the treatments with water and medium(WN10) or high N addition(WN20) significantly increased the cumulative N2O emissions(P<0.01) in both experimental periods. Under drought condition, the variations in soil N2O effluxes were positively correlated with the soil NH4-N concentrations in the three N input treatments(WN5, WN10, and WN20). Besides, the soil moisture and temperature also greatly influenced the N2O pulse emissions, particularly the N2O pulse under the relatively rainy soil condition or in the treatments without N addition(ZN and ZWN). The responses of the plant metabolism to the varying precipitation distribution and the length of drought period prior to rainfall could greatly affect the soil N dynamics and N2O emission pulses in semiarid grasslands. | XinChao LIU YuChun QI YunShe DONG Qin PENG YaTing HE LiangJie SUN JunQiang JIA CongCong CAO | 2014 | Journal of Arid Land2014，6，4： | 3 |

| 7 | A possible family of Ni-based high temperature superconductors显示文摘We suggest that a family of Ni-based compounds, which contain [Ni_2M_2O]~2à(M = chalcogen) layers with an antiperovskite structure constructed by mixed-anion Ni complexes, Ni M_4O_2, can be potential high temperature superconductors(high-Tc) upon doping or applying pressure. The layer structures have been formed in many other transitional metal compounds such as La_2B_2Se_2O_3(B = Mn, Fe, Co). For the Ni-based compounds, we predict that the parental compounds host collinear antiferromagnetic states similar to those in iron-based high temperature superconductors. The electronic physics near Fermi energy is controlled by two egd-orbitals with completely independent in-plane kinematics. We predict that the superconductivity in this family is characterized by strong competition between extended s-wave and d-wave pairing symmetries. | Congcong Le Jinfeng zeng Yuhao Gu Guang-Han Cao Jiangping Hu | 2018 | Science Bulletin2018，63，15： | 2 |
| 8 | Analysis of QTLs for erucic acid and oil content in seeds on A8 chromosome and the linkage drag between the alleles for the two traits in Brassica napus显示文摘The history of canola breeding began with the discovery of germplasm with low erucic acid content in seeds of spring forage cultivar in the 1950's.FAE1 mutations led to a dramatic decrease of the seed erucic acid content in Arabidopsis thaliana.The products of the two FAE1 loci,BnA8.FAE1 and BnC3.FAE1,showed additive effects to the level of erucic acid content in oilseed rape.Previous research believed that the pleiotropy of FAE1 was responsible for the decrease in seed oil content along with the reduction of seed erucic acid content in the modern cultivars.TN DH population was developed from a canola cultivar Tapidor and a Chinese traditional cultivar Ningyou7.The population had been tested in 10 and 11 environments to map QTLs for the erucic acid content and oil content in seeds.As the map resolution increased,a novel QTL for seed erucic acid content was revealed,after Meta-analysis,7 cM away from the most significant seed erucic acid content QTL where BnA8.FAE1 is located.Seven independent QTLs for seed oil content(qOC) were detected around the two seed erucic acid content QTLs(qEA) across 39.20 cM on linkage group A8.Two of the qOCs co-localized with the two qEAs,respectively,and were detected in a single environment.The other five qOCs were detected in 10 of 11 environments independent of qEAs.Alleles from Tapidor in all the QTLs at the 0-39.20 cM region contributed negative effects to either erucic acid content or oil content in seeds.Parallel,geno-typing showed that on 5 of the 7 QTLs regions,Tapidor alleles had the same genotypes with that in 'Liho',the original low seed erucic acid content source.Through rounds of crossbreeding with oil-cropped cultivars and intensive selection for multi generations,Tapidor still had the inferior alleles for low seed oil content from 'Liho',the forage rape.This showed a strong linkage drag of low seed oil content,which was controlled by the five qEA-independent qOCs,with low seed erucic acid content.Ninety cultivars of B.napus from 8 countries were used to analyze the genetic drag with 9 molecular markers located in the QTL confidence intervals(24.04 cM) on linkage group A8.It was noticed that more than 46% of the cultivars with low seed erucic acid content trait remained the genotype of low seed oil content at least in one locus.Backcross and marker-assisted selection could break the genetic drag between the low oil content and erucic acid in seeds in the process for breeding modern high seed oil content canola cultivars. | Zhengying Cao Fang Tian Nian Wang Congcong Jiang Bing Lin Wei Xia Jiaqin Shi Yah Long Chunyu Zhang Jinling Meng | 2010 | Journal of Genetics and Genomics2010，37，4： | 2 |
| 9 | A complete assembly of the rice Nipponbare reference genome显示文摘Dear Editor,In 2005,the current commonly used rice reference genome(Oryza sativa ssp.japonica cv.Nipponbare)was initially released by the International Rice Genome Sequencing Project(International Rice Genome Sequencing Project,2005).Thereafter,the reference genome was further updated in 2013 with improved genome assembly(IRGSP-1.0)and gene annotations(MSU7,RAP-DB)(Kawahara et al.,2013;Sakai et al.,2013).In the past 10 years,this reference has been serving as one of the most important genetic resources for subsequent rice functional genomics efforts.As several rice genomes had been assembled into gapless chromosomes with only 2–5 telomeres absent(Li et al.,2021;Song et al.,2021;Zhang et al.,2022),the IRGSP1.0 and its annotations still performed as the most widely used reference.However,limitations of sequencing technology and intricate genomic organization led to an under-representation of complex regions in this reference,leaving a total of 72 major gaps(including 19 telomeres),167 minor gaps,and 779 unknown bases(Kawahara et al.,2013),with an estimated length of3%of the genome unsolved. | Lianguang Shang Wenchuang He Tianyi Wang Yingxue Yang Qiang Xu Xianjia Zhao Longbo Yang Hong Zhang Xiaoxia Li Yang Lv Wu Chen Shuo Cao Xianmeng Wang Bin Zhang Xiangpei Liu Xiaoman Yu Huiying He Hua Wei Yue Leng Chuanlin Shi Mingliang Guo Zhipeng Zhang Bintao Zhang Qiaoling Yuan Hongge Qian Xinglan Cao Yan Cui Qianqian Zhang Xiaofan Dai Congcong Liu Longbiao Guo Yongfeng Zhou Xiaoming Zheng Jue Ruan Zhukuan Cheng Weihua Pan Qian Qian | 2023 | Molecular Plant2023，16，8： | 1 |
| 10 | Processing micrometer-sized particles in crumpled graphene network for freestanding membrane enabled by freeze casting显示文摘Graphene oxide(GO)is widely used in the construction and application of various 2 D membrane-based materials due to its unique colloidal structure.Herein,we demonstrate that micrometer-sized particles can make up freestanding membranes enabled by the extraordinary amphiphilic and polymer-like properties of graphene oxide through freeze casting.The 2 D macromolecule,GO could well wrap the particles for better uniformity and stability in either dispersion or membrane.Importantly,freeze casting plays an important role in avoiding the severe aggregation of micrometer-sized particles in the solventremoving process.After reduction,the membrane exhibits good electrical conductivity while maintaining its integral structure,which can be directly used as a freestanding binder-free electrode.This work provides a universal approach to fabricate freestanding membranes with various micrometersized materials for energy storage. | Jing Cao Xiaoli Zhao Jiahe Wang Huanglin Dou Congcong Liu Xiaojun Yan Yuantao Yan Min Guo Wanyu Zhao Xiaowei Yang | 2020 | Chinese Chemical Letters2020，31，1： | 1 |
| 11 | Porcine Picornavirus 3C Protease Degrades PRDX6 to Impair PRDX6-mediated Antiviral Function显示文摘Peroxiredoxin-6(PRDX6)is an antioxidant enzyme with both the activities of peroxidase and phospholipase A2(PLA2),which is involved in regulation of many cellular reactions.However,the function of PRDX6 during virus infection remains unknown.In this study,we found that the abundance of PRDX6 protein was dramatically decreased in foot-and-mouth disease virus(FMDV)infected cells.Overexpression of PRDX6 inhibited FMDV replication.In contrast,knockdown of PRDX6 expression promoted FMDV replication,suggesting an antiviral role of PRDX6.To explore whether the activity of peroxidase and PLA2 was associated with PRDX6-mediated antiviral function,a specific inhibitor of PLA2(MJ33)and a specific inhibitor of peroxidase activity(mercaptosuccinate)were used to treat the cells before FMDV infection.The results showed that incubation of MJ33 but not mercaptosuccinate promoted FMDV replication.Meanwhile,overexpression of PRDX6 slightly enhanced type I interferon signaling.We further determined that the viral 3Cprowas responsible for degradation of PRDX6,and 3Cpro-induced reduction of PRDX6 was independent of the proteasome,lysosome,and caspase pathways.The protease activity of 3Cprowas required for induction of PRDX6 reduction.Besides,PRDX6 suppressed the replication of another porcine picornavirus Senecavirus A(SVA),and the 3Cproof SVA induced the reduction of PRDX6 through its proteolytic activity as well.Together,our results suggested that PRDX6 plays an important antiviral role during porcine picornavirus infection,and the viral 3Cproinduces the degradation of PRDX6 to overcome PRDX6-mediated antiviral function. | Congcong Wang Huanhuan Feng Xiangle Zhang Kangli Li Fan Yang Weijun Cao Huisheng Liu Lili Gao Zhaoning Xue Xiangtao Liu Zixiang Zhu Haixue Zheng | 2021 | Virologica Sinica2021，36，5： | 1 |
| 12 | Yak rumen microbiome elevates fiber degradation ability and alters rumen fermentation pattern to increase feed efficiency显示文摘Rumen microbes play an important role in ruminant energy supply and animal performance.Previous studies showed that yak(Bos grunniens)rumen microbiome and fermentation differ from other ruminants.However,little is understood about the features of the rumen microbiome that make yak adapted to their unique environmental and dietary conditions.This study was to investigate the rumen microbiome and metabolome to understand how yak adapt to the coarse forage and harsh environment in the Qinghai-Tibetan plateau.Nine female Qaidam yellow cattle(Bos taurus),9 dzomo(hybrids of cattle and yak)and 9 female plateau yak(B.grunniens),about 5 to 6 years old,were used in this study.Rumen fermentation parameters,fibrolytic enzyme activities,and rumen metataxonomic were determined.Then 18(6 samples per group)were selected for rumen metagenomic and metabolome analysis.Metataxonomic analysis revealed that the rumen microbiota was significantly different among plateau yak,Qaidam yellow cattle,and dzomo(P<0.05).Metagenomic analysis displayed a larger gene pool encoding a richer repertoire of carbohydrate-active enzymes in the rumen microbiome of plateau yak and dzomo than Qaidam yellow cattle(P<0.05).Some of the genes encoding glycoside hydrolases that mediate the digestion of cellulose and hemicellulose were significantly enriched in the rumen of plateau yak than Qaidam yellow cattle,but glycoside hydrolase 57 that primarily includes amylases was abundant in Qaidam yellow cattle(P<0.05).The rumen fermentation profile differed also,Qaidam yellow cattle having a higher molar proportion of acetate but a lower molar proportion of propionate than dzomo and plateau yak(P<0.05).Based on metabolomic analysis,rumen microbial metabolic pathways and metabolites were different.Differential metabolites are mainly amino acids,carboxylic acids,sugars,and bile acids.Changes in rumen microbial composition could explain the above results.The present study showed that the rumen microbiome of plateau yak helps its host to adapt to the Qinghai-Tibetan plateau.In particular,the plateau yak rumen microbiome has more enzymes genes involved in cellulase and hemicellulase than that of cattle,resulting higher fibrolytic enzyme activities inyak,further providing stronger fiber degradation function. | Congcong Zhao Lamei Wang Shanlin Ke Xinhua Chen Akos Kenez Wei Xu Dangdang Wang Fan Zhang Yong Li Zhanhong Cui Yu Qiao Jing Wang Wenjuan Sun Jianhua Zhao Junhu Yao Zhongtang Yu Yangchun Cao | 2022 | Animal Nutrition2022，，4： | 1 |
| 13 | Effects of water and nitrogen addition on vegetation carbon pools in a semi-arid temperate steppe显示文摘Global change will lead to increases in regional precipitation and nitrogen(N) deposition in the semi-arid grasslands of northern China. We investigated the responses of vegetation carbon(C) pools to simulated precipitation and N deposition increases through field experiments in a typical steppe in Inner Mongolia. The treatments included NH_4NO_3 addition at concentrations of 0(CK), 5(LN, low nitrogen), 10(middle nitrogen, MN), and 20(HN,high nitrogen)(g m^(-2)a^(-1)) with and without water. After three consecutive years of treatment, from 2010 to 2012,water addition did not significantly change the size of the total vegetation C pools, but it significantly decreased the ratio of root:shoot(R:S)(P = 0.05) relative to controls. By contrast, N addition significantly increased the total vegetation C pools. The C pools in the LN, MN and HN treatments increased by 22, 39 and 44 %, respectively. MN produced the largest effect among the N concentrations,although differences between N-added treatments were not significant(P [ 0.05). N addition significantly reduced the ratio of root:shoot(R:S)(P = 0.03). However, there were no significant interactive effects of water and N addition on the vegetation C pools. | Junqiang Jia Yunshe Dong Yuchun Qi Qin Peng Xinchao Liu Liangjie Sun Shufang Guo Yunlong He Congcong Cao Zhongqing Yan | 2016 | Journal of Forestry Research2016，27，3： | 1 |

| 15 | Superior aggregation, morphology and photovoltaic performance enabled by fine tuning of fused electron-deficient units in polymer donors显示文摘Copolymerization of an electron-rich donor(D)unit with an electron-deficient acceptor(A)unit to construct efficient D-π-A-πtype donors is an effective strategy for organic solar cell applications.The electron-deficient unit fusion,endows extendedπ-conjugation plane and insures excellent photoelectronic property,has great advantages to build A moiety and gradually receives considerable attention.In this work,we adopt benzo[2,1-b:3,4-b’]dithiophene and benzopyrazine(BP),benzothiadiazole(BT)and benzoselenadiazole(BS)to cleverly construct a series of fused A units with different electrondeficient ability,and further synthesize three polymer donors PBDP-BP,PBDP-BT,and PBDP-BS,respectively.The relationships between structure and performance were systematically investigated.PBDPBT shows a moderate aggregation behavior in both solution and film,and the highest hole mobility among the three polymers.After blending with Y6,the PBDP-BT:Y6-based film has the strongest absorption,favorable compatibility,superior crystallinity,and uniform phase separation morphology compared with PBDP-BP or PBDP-BS based blend films.Thus,the device based on PBDP-BT:Y6 has the highest and balanced charge mobility,suppressive recombination,reduced energy loss and achieves an outstanding PCE of 15.14%,which is superior to PBDP-BP:Y6(8.55%)and PBDP-BS:Y6(6.85%).These results provide learnable guidelines for future fused electron-deficient unit-based donor design for photovoltaic application. | Mingrui Pu Xue Lai Hui Chen Congcong Cao Zixiang Wei Yulin Zhu Leilei Tian Feng He | 2023 | Journal of Energy Chemistry2023，，2： | 0 |
| 16 | Nitrogen-doped graphene as an excellent candidate for selective gas sensing显示文摘The toxic gases,such as CO and NO,are highly dangerous to human health and even cause the death of person and animals in a tiny amount.Therefore,it is very necessary to develop the toxic gas sensors that can instantly monitor these gases.In this work,we have used the first-principles calculations to investigate adsorption of gases on defective graphene nanosheets to seek a suitable material for CO sensing.Result indicates that the vancancy graphene can not selectivly sense CO from air,because O2 in air would disturb the sensing signals of graphene for CO,while the nitrogen-doped graphene is an excellent candidate for selectivly sensing CO from air,because only CO can be chemisorbed on the pyridinic-like N-doped graphene accompanying with a large charge transfer,which can serve as a useful electronic signal for CO sensing.Even in the environment with NO,the N-doped graphene can also detect CO selectively.Therefore,the N-doped graphene is an excellent material for selectively sensing CO,which provides useful information for the design and fabrication of the CO sensors. | MA CongCong SHAO XiaoHong CAO DaPeng | 2014 | Science China Chemistry2014，57，6： | 0 |
| 17 | Mechanical stretching boosts expansion and regeneration of intestinal organoids through fueling stem cell self-renewal显示文摘Intestinal organoids,derived from intestinal stem cell self-organization,recapitulate the tissue structures and behav-iors of the intestinal epithelium,which hold great potential for the study of developmental biology,disease modeling,and regenerative medicine.The intestinal epithelium is exposed to dynamic mechanical forces which exert profound effects on gut development.However,the conventional intestinal organoid culture system neglects the key role of mechanical microenvironments but relies solely on biological factors.Here,we show that adding cyclic stretch to intestinal organoid cultures remarkably up-regulates the signature gene expression and proliferation of intestinal stem cells.Furthermore,mechanical stretching stimulates the expansion of SOX9+progenitors by activating the Wnt/β-Catenin signaling.These data demonstrate that the incorporation of mechanical stretch boosts the stemness of intestinal stem cells,thus benefiting organoid growth.Our findings have provided a way to optimize an organoid generation system through understanding cross-talk between biological and mechanical factors,paving the way for the application of mechanical forces in organoid-based models. | Fanlu Meng Congcong Shen Li Yang Chao Ni Jianyong Huang Kaijun Lin Zanxia Cao Shicai Xu Wanling Cui Xiaoxin Wang Bailing Zhou Chunyang Xiong Jihua Wang Bing Zhao | 2022 | Cell Regeneration2022，11，1： | 0 |
| 18 | A centromere map based on super pan-genome highlights the structure and function of rice centromeres显示文摘Rice(Oryza sativa)is a significant crop worldwide with a genome shaped by various evolutionary factors.Rice centromeres are crucial for chromosome segregation,and contain some unreported genes.Due to the diverse and complex centromere region,a comprehensive understanding of rice centromere structure and function at the population level is needed.We constructed a high-quality centromere map based on the rice super pangenome consisting of a 251-accession panel comprising both cultivated and wild species of Asian and African rice.We showed that rice centromeres have diverse satellite repeat CentO,which vary across chromosomes and subpopulations,reflecting their distinct evolutionary patterns.We also revealed that long terminal repeats(LTRs),especially young Gypsy-type LTRs,are abundant in the peripheral CentO-enriched regions and drive rice centromere expansion and evolution.Furthermore,high-quality genome assembly and complete telomere-to-telomere(T2T)reference genome enable us to obtain more centromeric genome information despite mapping and cloning of centromere genes being challenging.We investigated the association between structural variations and gene expression in the rice centromere.A centromere gene,OsMAB,which positively regulates rice tiller number,was further confirmed by expression quantitative trait loci,haplotype analysis and clustered regularly interspaced palindromic repeats(CRISPR)/CRISPR-associated protein9 methods.By revealing the new insights into the evolutionary patterns and biological roles of rice centromeres,our finding will facilitate future research on centromere biology and crop improvement. | Yang Lv Congcong Liu Xiaoxia Li Yueying Wang Huiying He Wenchuang He Wu Chen Longbo Yang Xiaofan Dai Xinglan Cao Xiaoman Yu Jiajia Liu Bin Zhang Hua Wei Hong Zhang Hongge Qian Chuanlin Shi Yue Leng Xiangpei Liu Mingliang Guo Xianmeng Wang Zhipeng Zhang Tianyi Wang Bintao Zhang Qiang Xu Yan Cui Qianqian Zhang Qiaoling Yuan Noushin Jahan Jie Ma Xiaoming Zheng Yongfeng Zhou Qian Qian Longbiao Guo Lianguang Shang | 2024 | Journal of Integrative Plant Biology2024，66，2： | 0 |

| 20 | Engineering two-dimensional pores in freestanding TiO_2/graphene gel film for high performance lithium ion battery显示文摘As the key component of electrochemical energy storage devices, an electrode with superior ions transport pores is the important premise for high electrochemical performance. In this paper, we developed a unique solution process to prepare freestanding TiO_2/graphene hydrogel electrode with tunable density and porous structures. By incorporating room temperature ionic liquids(RTILs), even upon drying, the non-volatile RTILs that remained in the gel film would preserve the efficient ion transport channels and prevent the electrode from closely stacking, to develop dense yet porous structures. As a result, the dense TiO_2/graphene gel film as an electrode for lithium ion battery displayed a good gravimetric electrochemical performance and more importantly a high volumetric performance. | Xiaojun Yan Yuanyuan Wang Congcong Liu Min Guo Jingying Tao Jing Cao Dongju Fu Liyi Dai Xiaowei Yang | 2018 | Journal of Energy Chemistry2018，27，1： | 0 |
