| 2 | A Chromosome-Level Genome Assembly of Garlic (Allium sativum) Provides Insights into Genome Evolution and Allicin Biosynthesis显示文摘Garlic,an economically important vegetable,spice,and medicinal crop,produces highly enlarged bulbs and unique organosulfur compounds.Here,we report a chromosome-level genome assembly for garlic,with a total size of approximately 16.24 Gb,as well as the annotation of 57561 predicted protein-coding genes,making garlic the first Allium species with a sequenced genome.Analysis of this garlic genome assembly reveals a recent burst of transposable elements,explaining the substantial expansion of the garlic genome.We examined the evolution of certain genes associated with the biosynthesis of allicin and inulin neoseries-type fructans,and provided new insights into the biosynthesis of these two compounds.Furthermore,a large-scale transcriptome was produced to characterize the expression patterns of garlic genes in different tissues and at various growth stages of enlarged bulbs.The reference genome and large-scale transcriptome data generated in this study provide valuable new resources for research on garlic biology and breeding. | Xiudong Sun Siyuan Zhu Ningyang Li Yi Cheng Jing Zhao Xuguang Qiao Li Lu Shiqi Liu Yanzhou Wang Chan Liu Benping Li Wu Guo Shuang Gao Zemao Yang Fu Li Zheng Zeng Qing Tang Yupeng Pan Mengjiao Guan Jian Zhao Xiaomi ng Lu Huanwe n Meng Zhenlin Han Chun she ng Gao Wenkai Jiang Xing Zhao Shilin Tian Jianguang Su Zhihui Cheng Touming Liu | 2020 | Molecular Plant2020,13,9: | 14 |
| 3 | Gapless indica rice genome reveals synergistic contributions of active transposable elements and segmental duplications to rice genome evolution显示文摘The ultimate goal of genome assembly is a high-accuracy gapless genome.Here,we report a new assembly pipeline that is used to produce a gapless genome for the indica rice cultivar Minghui 63.The resulting 397.71-Mb final assembly is composed of 12 contigs with a contig N50 size of 31.93 Mb.Each chromosome is represented by a single contig and the genomic sequences of all chromosomes are gapless.Quality evaluation of this gapless genome assembly showed that gene regions in our assembly have the highest completeness compared with the other 15 reported high-quality rice genomes.Further comparison with the japonica rice genome revealed that the gapless indica genome assembly contains more transposable elements(TEs)and segmental duplications(SDs),the latter of which produce many duplicated genes that can affect agronomic traits through dose effect or sub-/neo-functionalization.The insertion of TEs can also affect the expression of duplicated genes,which may drive the evolution of these genes.Furthermore,we found the expansion of nucleotide-binding site with leucine-rich repeat disease-resistance genes and cis-zeatin-O-glucosyltransferase growth-related genes in SDs in the gapless indica genome assembly,suggesting that SDs contribute to the adaptive evolution of rice disease resistance and developmental processes.Collectively,our findings suggest that active TEs and SDs synergistically contribute to rice genome evolution. | Kui Li Wenkai Jiang Yuanyuan Hui Mengjuan Kong Li-Ying Feng Li-Zhi Gao Pengfu Li Shan Lu | 2021 | Molecular Plant2021,14,10: | 6 |
| 4 | The chromosome-level reference genome of Coptis chinensis provides insights into genomic evolution and berberine biosynthesis显示文摘Coptis chinensis Franch, a perennial herb, is mainly distributed in southeastern China. The rhizome of C. chinensis hasbeen used as a traditional medicine for more than 2000 years in China and many other Asian countries. Thepharmacological activities of C. chinensis have been validated by research. Here, we present a de novo high-qualitygenome of C. chinensis with a chromosome-level genome of ~958.20 Mb, a contig N50 of 1.58 Mb, and a scaffold N50of 4.53 Mb. We found that the relatively large genome size of C. chinensis was caused by the amplification of longterminal repeat (LTR) retrotransposons. In addition, a whole-genome duplication event in ancestral Ranunculales wasdiscovered. Comparative genomic analysis revealed that the tyrosine decarboxylase (TYDC) and (S)-norcoclaurinesynthase (NCS) genes were expanded and that the aspartate aminotransferase gene (ASP5) was positively selected inthe berberine metabolic pathway. Expression level and HPLC analyses showed that the berberine content was highestin the roots of C. chinensis in the third and fourth years. The chromosome-level reference genome of C. chinensisprovides important genomic data for molecular-assisted breeding and active ingredient biosynthesis. | Da-xia Chen Yuan Pan Yu Wang Yan-Ze Cui Ying-Jun Zhang Rang-yu Mo Xiao-li Wu Jun Tan Jian Zhang Lian-an Guo Xiao Zhao Wenkai Jiang Tian-lin Sun Xiao-Di Hu Long-yun Li | 2021 | Horticulture Research2021,8,1: | 2 |

| 7 | Echinacea purpurea-derived homogeneous polysaccharide exerts anti-tumor efficacy via facilitating M1 macrophage polarization显示文摘Echinacea purpurea modulates tumor progression,but the underlying mechanism is poorly defined.We isolated and purified a novel homogeneous polysaccharide from E.purpurea(EPPA),which was shown to be an arabinogalactan with a mean molecular mass(Mr)of 3.8×10^(4)Da and withα-(1→5)-L-Arabinan as the backbone and a-L-Araf-(1→,→6)-b-D-Galp-(1→,and →4)-α-D-GalpA-(1/as the side chains.Interestingly,oral administration of EPPA suppresses tumor progression in vivo and shapes the immune cell profile(e.g.,facilitating M1 macrophages)in tumor micro-environment by single-cell RNA sequencing(scRNA-seq)analysis. | Wenkai Ren Junfeng Ban Yaoyao Xia Fang Zhou Caihong Yuan Huanhuan Jia Hailan Huang Mingmin Jiang Minjian Liang Zhaodong Li Youyong Yuan Yulong Yin Hong Wu | 2023 | The Innovation2023,4,2: | 1 |
| 8 | A novel long-term intravenous combined with local treatment with human amnion-derived mesenchymal stem cells for a multidisciplinary rescued uremic calciphylaxis patient and the underlying mechanism显示文摘Calciphylaxis is a rare disease characterized histologically by microvessel calcification and microthrombosis,with high mortality and no proven therapy.Here,we reported a severe uremic calciphylaxis patient with progressive skin ischemia,large areas of painful malodorous ulcers,and mummified legs.Because of the worsening symptoms and signs refractory to conventional therapies,treatment with human amnion-derived mesenchymal stem cells(hAMSCs)was approved.Preclinical release inspections of hAMSCs,efficacy,and safety assessment,including cytokine secretory ability,immunocompetence,tumorigenicity,and genetics analysis in vitro,were introduced.We further performed acute and long-term hAMSC toxicity evaluations in C57BL/6 mice and rats,abnormal immune response tests in C57BL/6 mice,and tumorigenicity tests in neonatal Balbc-nu nude mice.After the preclinical research,the patient was treated with hAMSCs by intravenous and local intramuscular injection and external supernatant application to the ulcers.When followed up to 15 months,the blood-based markers of bone and mineral metabolism improved,with skin soft tissue regeneration and a more favorable profile of peripheral blood mononuclear cells.Skin biopsy after 1-month treatment showed vascular regeneration with mature noncalcified vessels within the dermis,and 20 months later,the re-epithelialization restored the integrity of the damaged site.No infusion or local treatment-related adverse events occurred.Thus,this novel long-term intravenous combined with local treatment with hAMSCs warrants further investigation as a potential regenerative treatment for uremic calciphylaxis due to effects of inhibiting vascular calcification,stimulating angiogenesis and myogenesis,anti-inflammatory and immune modulation,multidifferentiation,re-epithelialization,and restoration of integrity. | Lianju Qin Jing Zhang Yujie Xiao Kang Liu Yugui Cui Fangyan Xu Wenkai Ren Yanggang Yuan Chunyan Jiang Song Ning Xiaoxue Ye Ming Zeng Hanyang Qian Anning Bian Fan Li Guang Yang Shaowen Tang Zhihong Zhang Juncheng Dai Jing Guo Qiang Wang Bin Sun Yifei Ge Chun Ouyang Xueqiang Xu Jing Wang Yaoyu Huang Hongqing Cui Jing Zhou Meilian Wang Zhonglan Su Yan Lu Di Wu Jingping Shi Wei Liu Li Dong Yinbing Pan Baiqiao Zhao Ying Cui Xueyan Gao Zhanhui Gao Xiang Ma Aiqin Chen Jie Wang Meng Cao Qian Cui Li Chen Feng Chen Youjia Yu Qiang Ji Zhiwei Zhang Mufeng Gu Xiaojun Zhuang Xiaolin Lv Hui Wang Yanyan Pan Ling Wang Xianrong Xu Jing Zhao Xiuqin Wang Cuiping Liu Ningxia Liang Changying Xing Jiayin Liu Ningning Wang | 2022 | Journal of Molecular Cell Biology2022,14,2: | 1 |
| 9 | Large-scale controllable fabrication of aluminum nanobowls for surface plasmon-enhanced fluorescence显示文摘Al nanoparticles(NPs)exhibit excellent localized surface plasmon resonance(LSPR)properties and have been considered a promising alternative to plasmonic Au or Ag NPs.However,it remains difficult to fabricate Al NPs with uniform size and controllable morphology over a large area on substrates,which seriously hinders the in-depth exploration of their properties and applications.Herein,we have developed a self-assembly nanoparticle template method to realize the controllable preparation of bowl-shaped Al NPs(Al nanobowls(Al NBs))with tunable sizes from 36 to 131 nm on the substrate surface,accompanied by tunable LSPR spectral responses from 272 to 480 nm.Among them,131 nm Al NBs exhibit superior fluorescence enhancement ability(1932.2-fold)and a low detection limit(78.6 pM)towards 5-carboxyfluorescein,exceeding comparable Ag NBs and Au nanospheres(NSs).This can be attributed to the strong electromagnetic enhancement induced by the LSPR effect and the effective inhibition of fluorescence quenching caused by the self-passivated oxide layer.Therefore,the successful fabrication of Al NBs on substrates is of vital significance for their promising applications,including surface-enhanced spectroscopy,sensitive fluorescence detection,light-harvesting devices,biosensing,and ultraviolet(UV)plasmonics. | Yawen Wang Heng Gao Yuanlan Liu Dong Li Bo Zhao Wenkai Liang Yinghui Sun Lin Jiang | 2023 | Nano Research2023,16,7: | 0 |
| 10 | Neither Fluorocarbons nor Silicones:Hydrocarbon-Based Water-Borne Healable Supramolecular Elastomer with Unprecedent Dual Resistance to Water and Organic Solvents显示文摘Except for fluorocarbons and silicones,few artificial materials display both water and organic solvent resistance.Herein,we report an artificial hydrocarbonbased supramolecular elastomer that displays unprecedented dual resistance to both water and organic solvents.This elastomer is formed in water with two water soluble components,folic acid(FA)and branched poly(ethylene imine)(b-PEI).The hydrogen bonding between the two components occurs immediately,which further promotes the hydrogen bonding between the FA,yielding folate quartets and theirπ-πstacking.These multiple noncovalent interactions work synergistically,leading to a hydrophobic,transparent,stretchable,healable,notchinsensitive,and recyclable elastomer that resists both water and organic solvents.The elastomer remains intact after storage in high humidity and organic solvents for months.Films generated by stretching the elastomer are very hydrophobic,and the contact angle of water on the elastomer is up to 112.3°.The damaged elastomers also exhibit water-assisted healable behavior.This work discloses a new paradigm of material synthesis that can inspire the fabrication of robust nonfluorocarbon and silicone-based materials with green strategies. | Shuitao Gao Shasha Jiang Jinwan Qi Tongyue Wu Wenkai Wang Zhijie Liu Bin Zhang Jianbin Huang Yun Yan | 2022 | CCS Chemistry2022,4,12: | 0 |
| 11 | Facile fabrication of a single-particle platform with high throughput via substrate surface potential regulated large-spacing nanoparticle assembly显示文摘Nanodevices based on the single nanoparticle represent innovative and promising technology,which could satisfy the increasing requirements of high accuracy,low energy consumption,and small volume.However,the acquisition of single particles involves complex operation,and the corresponding nanodevices display low-throughput.Herein,we present a facile strategy to construct a single-particle platform with high throughput via substrate surface potential modulated a large-area and large-spacing nanoparticle assembly.Such platform not only avoids optic interference but also ensures the independent electrically conductive channel of single particle on substrate.Therefore,the dark-field microscopic imaging and single-particle scattering signals collecting of individual nanoparticles with plasmonic effect are satisfactory achieved based on the platform,and the first success in the fabrication of nano-organic-light-emitting-diodes with single nanoparticle resolution in nanoscale.All the results indicate that the strategy may find promising applications in the in situ single-particle research such as single-particle detection,singleparticle catalysis,and optoelectronics. | Dong Li Yinghui Sun Yawen Wang Yuanlan Liu Bo Zhao Wenkai Liang Heng Gao Lin Jiang | 2022 | Nano Research2022,15,7: | 0 |
| 12 | Tailoring Texture to Highly Strengthen AZ31 Alloy Plate in the Thickness Direction via Pre-tension and Rolling-Annealing显示文摘Conventional wrought Mg alloys,such as AZ31 and ZK60 rolled plates,usually exhibit significantly low tensile yield strength in the thickness direction.This can be attributed to the high activity of{10-12}tension twinning due to the strong basal texture(<0001>//ND,normal direction).In this work,the tensile yield strength in the ND of the as-rolled(AR)AZ31 plate increased from 50 to 150 MPa(increased by 200%)via simple processing,i.e.,pre-tension and rolling-annealing(PTRA)treatment.The strong basal texture(<0001>//ND)of the AR plate was changed into a weakened fiber texture(<0001>⊥ND).The evolution of microstructures during PTRA treatment and the activated deformation modes during uniaxial tension were studied quantitatively and statistically by the means of intergranular misorientation(IM)and in-grain misorientation axes(IGMA)analysis.The results indicate that various twin variants,as well as{10-12}-{10-12}secondary twins,were activated during pre-tension and rolling,and most residual matrix was consumed by twins after annealing.The dominated deformation modes in tension changed from{10-12}tension twinning(the AR sample)to prismatic slip(the PTRA sample)in the early tensile deformation.The underlying formation mechanism of the fiber texture and corresponding strengthening mechanism were discussed. | Tianjiao Li Jiang Zheng Lihong Xia Haoge Shou Yongfa Zhang Rong Shi Liuyong He Wenkai Li | 2023 | Acta Metallurgica Sinica(English Letters)2023,36,2: | 0 |
| 13 | On-chip photonic spatial-temporal descrambler显示文摘As an indispensable part to compensate for the signal crosstalk in fiber communication systems,conventional digital multi-input multi-output(MIMO)signal processor is facing the challenges of high com-putational complexity,high power consumption and relatively low processing speed.The optical MIMOenables the best use of light and has been proposed to remedy this limitation.However,the currently existing optical MIMO methods are all restricted to the spatial di-mension,while the temporal dimension is neglected.Here,an on-chip spatial-temporal descrambler with four channels were devised and its MIMO functions were experimentally verified simultaneously in both spatial and temporal dimensions.The spatial crosstalk of single-channel descrambler and four-channel descrambler is respectively less than-21 dB and-18 dB,and the time delay is simultaneously com-pensated successfully.Moreover,a more universal model extended to mode-dependent loss and gain(MDL)compensation was further de-veloped,which is capable of being cascaded for the real optical trans-mission system.The first attempt at photonic spatial-temporal de-scrambler enriched the varieties of optical MIMO,and the proposed scheme provided a new opportunity for all-optical MIMO signal pro-cessing. | Wenkai Zhang Xueyi Jiang Wentao Gu Junwei Cheng Hailong Zhou Jianji Dong Dongmei Huang Xinliang Zhang | 2023 | Chip2023,2,2: | 0 |
| 14 | Betulinic acid-mediating miRNA-365 inhibited the progression of pancreatic cancer显示文摘Background:The dilemma of pancreatic cancer treatment has become a global challenge.For this reason,effective,feasible,and new medical methods are currently much-needed.Betulinic acid(BA)has been valued as a potential therapy for pancreatic cancer.However,the mechanism by which BA exerts an inhibitory effect on the development of pancreatic cancer remains elusive.Methods:A rat model and two cell models of pancreatic cancer were established,and the effect of BA on pancreatic cancer was verified in vivo and in vitro by using MTT,Transwell,flow cytometry,RT-PCR,Elisa and immunohistochemistry.At the same time,miR-365 inhibitors were introduced to test whether BA played a role in mediating miR-365.Results:BA can significantly inhibit the proliferation and invasion of pancreatic cancer cells and promote apoptosis.In vivo experiments,BA can significantly lower the number of cancer cells and tumor volume in the rat model of pancreatic cancer.In vitro,it was found that BA inhibited the protein level and phosphorylation level of AKT/STAT3 by mediating the expression of miR365/BTG2/IL-6.Like BA,miR-365 inhibitors also significantly inhibited cell viability and invasion ability,and inhibited the protein level and phosphorylation level of AKT/STAT3 by changing the expression of BTG2/IL-6,and their combination had a synergistic effect.Conclusion:BA inhibits AKT/STAT3 expression and phosphorylation by modulating miR-365/BTG2/IL-6 expression,and BA inhibits the progression of pancreatic cancer through the aforementioned mechanism. | XIN LI WENKAI JIANG WANCHENG LI SHI DONG YAN DU HUI ZHANG WENCE ZHOU | 2023 | Oncology Research2023,31,4: | 0 |
| 15 | Solid-phase molecular self-assembly facilitated supramolecular films with alternative hydrophobic/hydrophilic domains for skin moisture detection显示文摘Human skin moisture is closely related to health and personal care issues.Many creams were developed to claim capable of skin moisturizing.However,people can hardly check their skin moisture status and the moisturizing effect of various creams conveniently,since currently all the skin moisturizing detection rely on large equipment requiring power supply.Herein,we report a power-supply independent supramolecular film that is able to directly report the moisturizing status of the skin.With the strategy of solid-phase molecular self-assembly(SPMSA),the aqueous precipitates formed by commercially available polyelectrolyte and oppositely charged surfactant would transform into a supramolecular film under a mild mechanical pressure,where the hydrophobic surfactant domains bridged by polyelectrolyte merge into hydrophobic mesophases to reduce interfacial energy.The hydrophobic mesophase will greatly retard water diffusion inside the film,so that a humidity gradient is generated as the film is exposed to a humid environment.The film will bend upward automatically in touch with moisture skin,and the bending degree is proportional to the skin moisture status.Therefore,the film can be used as portable smart power-free skin moisture sensor. | Jinwan Qi Tongyue Wu Wenkai Wang Hongjun Jin Shuitao Gao Shasha Jiang Jianbin Huang Yun Yan | 2022 | Aggregate2022,3,2: | 0 |

| 17 | Rational Design of Plasmonic Metal Nanostructures for Solar Energy Conversion显示文摘Plasmonic metal nanostructures,possessing unique surface plasmon resonance properties,show excellent capabilities for light trapping and coupling.On this basis,various plasmonic metal nanostructures offer extraordinary opportunities to promote the conversion efficiency of solar energy to electric energy,hydrogen energy or thermal energy,and so on.In this review article,we highlight a number of recent research achievements on the rational design of plasmonic metal nanostructures so as to maximize the utilization of the entire solar spectrum.Compared with single metal nanoparticles,multiplex(such as multicompositions,sizes,or shapes)nanoparticle structures emphasize advantages in broadening the absorption range and improving light-utilization efficiency.This review concludes with discussions regarding challenges in this research field and proposals of prospects for future directions. | Yawen Wang Junchang Zhang Wenkai Liang He Yang Tianfu Guan Bo Zhao Yinghui Sun Lifeng Chi Lin Jiang | 2022 | CCS Chemistry2022,4,4: | 0 |
| 18 | ReDB:A meiotic homologous recombination rate database显示文摘Meiotic recombination occurs preferentially at certain regions in the genome referred to as hot spots which are important for generating genetic diversity and proper segregation of chromosomes during meiosis.Although observations concerning individual hotspots have given clues as to the mechanism of recombination initiation,the nature and causes of recombination rate variation in the genome are still little known.A rational solution is to estimate and rank recombination rates along the genome.Therefore,it is a high demand for a database that deposits and integrates those data to provide a systematical repository of genome-wide recombination rates.Homologous recombination hotspots database is a web-based database of meiotic recombination rates,which comprises enormous data and information of human,mouse,rat,D.melanogaster,C.elegans and yeast.Users can query the database in several alternative ways.The database stores various details for every sequence,such as chromosome number,hyperlinks to the respective reference,and the sequence in FASTA format. | SANG Fei JIANG Peng WANG WenKai LU ZuHong | 2010 | Chinese Science Bulletin2010,55,27: | 0 |
| 19 | Developing Zn–1.5Mg Alloy with Simultaneous Improved Strength,Ductility and Suitable Biodegradability by Rolling at Room Temperature显示文摘This study systematically investigated the influence of the microstructure evolution,mechanical properties and corrosion behaviors on Zn–1.5Mg(wt%)alloy processed by room-temperature rolling.The as-cast Zn–1.5Mg alloy consists ofη-Zn matrix andη-Zn+Mg_(2)Zn_(11)eutectic structure.As rolling reduction increases,the average grain size of the alloy reduces from 42.9 to 1.7μm,and the eutectic structure undergoes fragmentation and refinement,changing from a network distribution surrounding the matrix to a lamellar alternating distribution with the matrix.The ultimate tensile strength of the as-rolled alloy(80%reduction)is increased to 366±3.7 MPa,along with a good elongation of 18.4%±2.0%.Immersion tests in Hanks’solution indicate that the initial corrosion rate of the 80%-rolled alloy is 0.030 mm/year and finally stabilizes at 0.034 mm/year when the immersion duration is extended to 21 days.According to X-ray diffractometer and X-ray photoelectron spectroscopy analyses,Ca_(3)(PO_(4))_(2),CaCO_(3),Ca(OH)_(2),Zn_(3)(PO_(4))_(2),Zn(OH)_(2),ZnO and a small amount of MgO and MgCO_(3)are the main corrosion products on the surface.Due to the microstructure refinement,the developed alloy exhibits uniform corrosion,and the corrosion morphology is dominated by pitting pits. | Ziyue Xu Huan Liu Guangyang Hu Xiaoru Zhuo Kai Yan Jia Ju Wenkai Wang Hang Teng Jinghua Jiang Jing Bai | 2023 | Acta Metallurgica Sinica(English Letters)2023,36,11: | 0 |
| 20 | Optical engineering of infrared PbS CQD photovoltaic cells for wireless optical power transfer systems显示文摘Infrared photovoltaic cells(IRPCs)have attracted considerable attention for potential applications in wireless optical power transfer(WOPT)systems.As an efcient fber-integrated WOPT system typically uses a 1550 nm laser beam,it is essential to tune the peak conversion efciency of IRPCs to this wavelength.However,IRPCs based on lead sulfde(PbS)colloidal quantum dots(CQDs)with an excitonic peak of 1550 nm exhibit low short circuit current(Jsc)due to insufcient absorption under monochromatic light illumination.Here,we propose comprehensive optical engineering to optimize the device structure of IRPCs based on PbS CQDs,for 1550 nm WOPT systems.The absorption by the device is enhanced by improving the transmittance of tin-doped indium oxide(ITO)in the infrared region and by utilizing the optical resonance efect in the device.Therefore,the optimized device exhibited a high short circuit current density of 37.65 mA/cm^(2)under 1 sun(AM 1.5G)solar illumination and 11.91 mA/cm^(2)under 1550 nm illumination 17.3 mW/cm^(2).Furthermore,the champion device achieved a record high power conversion efciency(PCE)of 7.17%under 1 sun illumination and 10.29%under 1550 nm illumination.The PbS CQDs IRPCs under 1550 nm illumination can even light up a liquid crystal display(LCD),demonstrating application prospects in the future. | Mengqiong Zhu Yuanbo Zhang Shuaicheng Lu Zijun Wang Junbing Zhou Wenkai Ma Ruinan Zhu Guanyuan Chen Jianbing Zhang Liang Gao Jiancan Yu Pingqi Gao Jiang Tang | 2023 | Frontiers of Optoelectronics2023,16,2: | 0 |
