| 1 | SQUAMOSA Promoter-Binding Protein-Like Transcription Factors:Star Players for Plant Growth and Development显示文摘SQUAMOSA Promoter-Binding Protein-Like (SPL) genes encode plantspecific transcription factors that play important roles in plant phase transition,flower and fruit development,plant architecture,gibberellins signaling,sporogenesis,and response to copper and fungal toxins.In Arabidopsis,many SPL genes are post-transcriptionally regulated by the microRNA (miRNA) miR156,among which AtSPL9 in turn positively regulates the expression of the second miRNA miR172.This miR156AtSPL9-miR172 regulatory pathway plays critical roles during juvenile to adult leaf development and the miR156-SPLs feedback interaction persists all through the plant development,which may be conserved in other plants.In the present paper,we provide a concise review on the most recent progress in the regulatory mechanisms associated with plant SPL transcription factors,especially in relation to miRNAs.The potential application of these discoveries in agriculture is briefly discussed. | Xiaobo Chen Zenglin Zhang Danmei Liu Kai Zhang Aili Li Long Mao | 2010 | Journal of Integrative Plant Biology2010,52,11: | 31 |
| 2 | Hydrogen sulfide promotes flowering in heading Chinese cabbage by S-sulfhydration of BraFLCs显示文摘Heading Chinese cabbage(Brassica rapa L.syn.B.campestris L.ssp.chinensis Makino var.pekinensis(Rupr.)J.Cao et Sh.Cao)is a cruciferous Brassica vegetable that has a triplicate genome,owing to an ancient genome duplication event.It is unclear whether the duplicated homologs have conserved or diversi fied functions.Hydrogen sulfide(H_(2)S)is a plant gasotransmitter that plays important physiological roles in growth,development,and responses to environmental stresses.The modification of cysteines through S-sulfhydration is an important mechanism of H_(2)S,which regulates protein functions.H?S promotes flowering in Arabidopsis and heading Chinese cabbage.Here we investigated the molecular mechanisms of H_(2)S used to promote flowering in the latter.Four,five,and four BraFLC,BraSOC I,and BraFT homologs were identi fi ed in heading Chinese cabbage.Different BraFLC proteins were bound to different CArG boxes in the promoter regions of the BraSOC I and BraFT homologs,producing different binding patterns.Thus,there may be functionally diverse BraFLC homologs in heading Chinese cabbage.Exogenous H_(2)S at 100μmol L^(-1) significantly promoted flowering by compensating for insuf fi cient vernalization.BraFLC 1 and BraFLC_(3) underwent S-sulfhydration by H_(2)S,after which their abilities to bind most BraSOC I or BraFT promoter probes weakened or even disappeared.These changes in binding ability were consistent with the expression pattern of the BraFT and BraSOC I homologs in seedlings treated with H_(2)S.These results indicated that H_(2)S signaling regulates flowering time.In summary,H_(2)S signaling promoted plant flowering by weakening or eliminating the binding abilities of BraFLCs to downstream promoters through S-sulfhydration. | Xiaoli Ma Liping Zhang Zhuoya Pei Linlin Zhang Zhiqiang Liu Danmei Liu Xuefeng Hao Zhuping Jin Yanxi Pei | 2021 | Horticulture Research2021,8,1: | 6 |
| 3 | Analysis of the growth of GaN epitaxy on silicon显示文摘Due to the great potential of Ga N based devices, the analysis of the growth of crack-free Ga N with high quality has always been a research hotspot. In this paper, two methods for improving the property of the Ga N epitaxial layer on Si(111) substrate are researched. Sample A, as a reference, only has an Al N buffer between the Si substrate and the epitaxy. In the following two samples, a Ga N transition layer(sample B) and an Al Ga N buffer(sample C) are grown on the Al N buffer separately. Both methods improve the quality of Ga N. Meanwhile, using the second method, the residual tensile thermal stress decreases. To further study the impact of the two introduced layers, we investigate the stress condition of Ga N epitaxial layer by Raman spectrum. According to the Raman spectrum, the calculated residual stress in the Ga N epitaxial layer is approximately 0.72 GPa for sample B and0.42 GPa for sample C. The photoluminescence property of Ga N epitaxy is also investigated by room temperature PL spectrum. | Danmei Zhao Degang Zhao | 2018 | Journal of Semiconductors2018,39,3: | 5 |
| 4 | Hydrogen sulfide inhibits ethylene-induced petiole abscission in tomato(Solanum lycopersicum L.)显示文摘Abscission is a dynamic physiological process that is ubiquitous in plants and can also be an essential agronomic trait in crops,thus attracting attention from plant growers and breeders.In general,the process of plant organ abscission can be divided into four steps,among which the step to obtain the competence to respond to abscission signals(step 2)is the most complex;however,the molecular mechanism underlying this process remains unclear.In this study,we found that hydrogen sulfide(H_(2)S)inhibited the abscission of the tomato petiole in a dose-dependent manner,and the abscission of the petiole was accelerated when an H_(2)S scavenger was applied.Further enzymatic activity and gene expression analyses showed that H_(2)S suppressed the activity of enzymes capable of modifying the cell wall by inhibiting the usual upregulation of the transcription of the corresponding genes during the abscission process but not by affecting the activities of these enzymes by direct posttranslational modification.H_(2)S treatment upregulated the expression levels of SlIAA3 and SlIAA4 but downregulated the transcription of ILR-L3 and ILR-L4 in the earlier stages of the abscission process,indicating that H_(2)S probably functioned in the second step of the abscission process by preventing the abscission zone cells from obtaining the competence to respond to abscission signals by modulating the content of the bioactive-free auxin in these cells.Moreover,similar H_(2)S inhibitory effects were also demonstrated in the process of floral organ abscission and anther dehiscence in other plant species,suggesting a ubiquitous role for H_(2)S in cell separation processes. | Danmei Liu Jianing Li Zhuowen Li Yanxi Pei | 2020 | Horticulture Research2020,7,1: | 4 |
| 5 | Mechanical activation of spike fosters SARS-CoV-2 viral infection显示文摘The outbreak of SARS-CoV-2(SARS2)has caused a global COVID-19 pandemic.The spike protein of SARS2(SARS2-S)recognizes host receptors,including ACE2,to initiate viral entry in a complex biomechanical environment.Here,we reveal that tensile force,generated by bending of the host cell membrane,strengthens spike recognition of ACE2 and accelerates the detachment of spike’s S1 subunit from the S2 subunit to rapidly prime the viral fusion machinery.Mechanistically,such mechano-activation is fulfilled by force-induced opening and rotation of spike’s receptor-binding domain to prolong the bond lifetime of spike/ACE2 binding,up to 4 times longer than that of SARS-S binding with ACE2 under 10 pN force application,and subsequently by force-accelerated S1/S2 detachment which is up to~103 times faster than that in the no-force condition.Interestingly,the SARS2-S D614G mutant,a more infectious variant,shows 3-time stronger force-dependent ACE2 binding and 35-time faster force-induced S1/S2 detachment.We also reveal that an anti-S1/S2 non-RBD-blocking antibody that was derived from convalescent COVID-19 patients with potent neutralizing capability can reduce S1/S2 detachment by 3×106 times under force.Our study sheds light on the mechano-chemistry of spike activation and on developing a non-RBD-blocking but S1/S2-locking therapeutic strategy to prevent SARS2 invasion. | Wei Hu Yong Zhang Panyu Fei Tongtong Zhang Danmei Yao Yufei Gao Jia Liu Hui Chen Qiao Lu Tenny Mudianto Xinrui Zhang Chuxuan Xiao Yang Ye Qiming Sun Jing Zhang Qi Xie Pei-Hui Wang Jun Wang Zhenhai Li Jizhong Lou Wei Chen | 2021 | Cell Research2021,31,10: | 2 |
| 6 | Interspecific plant interaction via root exudates structures the disease suppressiveness of rhizosphere microbiomes显示文摘Terrestrial plants can affect the growth and health of adjacent plants via interspecific interaction.Here,we studied the mechanism by which plant root exudates affect the recruitment of the rhizosphere microbiome in adjacent plants—with implications for plant protection—using a tomato(Solanum lycopersicum)–potatoonion(Allium cepa var.agrogatum)intercropping system.First,we showed that the intercropping system results in a disease-suppressive rhizosphere microbiome that protects tomato plants against Verticillium wilt disease caused by the soilborne pathogen Verticillium dahliae.Second,16S rRNA gene sequencing revealed that intercropping with potatoonion altered the composition of the tomato rhizosphere microbiome by promoting the colonization of specific Bacillus sp.This taxon was isolated and shown to inhibit V.dahliae growth and induce systemic resistance in tomato plants.Third,a belowground segregation experiment found that root exudates mediated the interspecific interaction between potatoonion and tomato.Moreover,experiments using split-root tomato plants found that root exudates from potatoonion,especially taxifolin—a flavonoid compound—stimulate tomato plants to recruit plant-beneficial bacteria,such as Bacillus sp.Lastly,ultra-high-pressure liquid chromatography–mass spectrometry analysis found that taxifolin alters tomato root exudate chemistry;thus,this compound acts indirectly in modulating root colonization by Bacillus sp.Our results revealed that this intercropping system can improve tomato plant fitness by changing rhizosphere microbiome recruitment via the use of signaling chemicals released by root exudates of potatoonion.This study revealed a novel mechanism by which interspecific plant interaction modulates the establishment of a disease-suppressive microbiome,thus opening up new avenues of research for precision plant microbiome manipulations. | Xingang Zhou Jingyu Zhang Muhammad Khashi u Rahman Danmei Gao Zhong Wei Fengzhi Wu Francisco Dini-Andreote | 2023 | Molecular Plant2023,16,5: | 2 |

| 13 | The preparation and performance of high activity Ni-Cr binary catalysts for direct borohydride fuel cells显示文摘Ni-Cr binary anode catalysts used in direct borohydride fuel cells (DBFCs) were prepared using a constant potential electrodepo- sition method. Compared with pure metal Ni catalysts, the electro-oxidation currents of borohydride ions (BH-4) more than doubled when using Ni-Cr binary catalysts under the same conditions. The enhanced activity of the Ni-Cr binary catalysts could be attributed to the change in distribution of BH-4ions on the surface of the Ni electrode. This is due to Cr electrodeposits, which allows a greater number of hydrogen atoms to catalyze from each tetrahedron BH-4 ion. The performance of Ni-Cr binary catalysts could also be improved by optimizing the electrodeposition conditions. The results show that Ni-Cr binary catalysts are optimally prepared using an electrodeposition method of 1s with a Cr3+ concentration of 0.2 mol L-1 and a potential of -0.100 V. | YU DanMei SHEN Yan YE Zhen WEN JiaZhi WANG Jie CHEN ChangGuo | 2013 | Chinese Science Bulletin2013,58,20: | 1 |

| 16 | Adaptive backstepping-based NTSM control for unmatched uncertain nonlinear systems显示文摘An adaptive backstepping-based non-singular terminal sliding mode(NTSM) control method is proposed for a class of uncertain nonlinear systems in the parameteric-strict feedback form. The adaptive control law is combined with the first n- 1steps of the backstepping method to estimate the unknown parameters of the system. In the nth step, an NTSM control strategy is utilized to drive the last state of the system to converge in a finite time. Furthermore, the derivate estimator is used to obtain the derivates of the states of the error system; the higher-order non-singular terminal sliding mode control(HONTSMC) law is designed to eliminate the chattering and make the system robust to both matched and unmatched uncertainties. Compared to the adaptive backstepping-based linear sliding mode control method(LSMC), the proposed method improves the convergence rate and the steady-state tracking accuracy of the system, and makes the control signal smoother. Finally, the compared simulation results are presented to validate the method. | Xuemei Zheng Peng Li Haoyu Li Danmei Ding | 2015 | Journal of Systems Engineering and Electronics2015,26,3: | 1 |

| 18 | Disclination and molecular director studies on bowlic columnar nematic phase using mosaic-like morphologydecoration method显示文摘Two bowlic cyclotriveratrylene CTV-1 and CTV-2, with different peripheral groups of -OCH3 and -OCH2CH3 for CTV-1 and -OCH3 and -OCH2COOCH3 for CTV-2, respectively, were synthesized by typical trimerization via a multistep sequence from vanillin. Both bowlic CTV molecules were thermotropic liquid crystals, and presented typical grainy textures of the nematic phase and homogeneous texture of the single domain nematic phase. It is of interest to observe the regular and beautiful mosaic-like morphologies after cooling from liquid crystalline phases, which appeared and vanished repeatedly in several circles of cooling and heating. The size of each mosaic was several dozens of micron. In nature, the mosaic-like morphologies are the optical pattern of cracks formed by the shrinking, due to the crystallization of frozen texture of nematic phases. By means of scanning electron microscopy, the mosaic-like morphologies were observed to consist of lamellae, and each mosaic is a rectangular multi-layer lamella, which is composed of packed single-layered lamellae. The fibrils in the diameter of about 1 μm were observed, which are the structural units of lamellae and would be the bundles of the bowlic molecular columns. The mosaic-like morphologies decorate the bowlic molecular columnar nematic phase, therefore, a novel mosaic-like morphologies decoration method was applied to reveal the director distribution of several kinds of point disclinations, such as s = +1(δ =0°and δ =90°) and s = ±1/2, and Nèel domain walls. It was shown that the bowlic molecular columnar nematic phase behaved as normal nematic phases; however, the basic structural units ordered were the bowlic molecular column or the bundles of bowlic molecular column (i.e. fibrils), but not the bowlic molecules themselves. The bowlic molecular columns acted as the rod-like molecules in a normal nematic phase. Therefore, a new term BCN (bowlic columnar nematic phase) is used to describe the anomalous nematic phase in this paper. | DONG YanMing CHEN DanMei ZENG ErMan HU XiaoLan ZENG ZhiQun | 2009 | Science China Chemistry2009,52,7: | 1 |
| 19 | Symmetry selective directionality in near-field acoustics显示文摘Understanding unidirectional and topological wave phenomena requires the unveiling of intrinsic geometry and symmetry for wave dynamics.This is essential yet challenging for the flexible control of near-field evanescent waves,highly desirable in broad practical scenarios ranging from information communication to energy radiation.However,exploitations of near-field waves are limited by a lack of fundamental understanding about inherent near-field symmetry and directional coupling at sub-wavelengths,especially for longitudinal waves.Here,based on the acoustic wave platform,we show the efficient selective couplings enabled by near-field symmetry properties.Based on the inherent symmetry properties of three geometrically orthogonal vectors in near-field acoustics,we successfully realize acoustic Janus,Huygens,spin sources and quadrupole hybrid sources,respectively.Moreover,we experimentally demonstrate fertile symmetry selective directionality of those evanescent modes,supported by two opposite meta-surfaces.The symmetry properties of the near-field acoustic spin angular momenta are revealed by directly measuring local vectorial fields.Our findings advance the understanding of symmetries in near-field physics,supply feasible approaches for directional couplings,and pave the way for promising acoustic devices in the future. | Yang Long Hao Ge Danmei Zhang Xiangyuan Xu Jie Ren Ming-Hui Lu Ming Bao Hong Chen Yan-Feng Chen | 2020 | National Science Review2020,7,6: | 1 |
| 20 | In vitro genotoxicity evaluation and metabolic study of residual glutaraldehyde in animal-derived biomaterials显示文摘Glutaraldehyde(GA)is an important additive that is mainly used in animal-derived biomaterials to improve their mechanical and antimicrobial capacities.However,GA chemical toxicity and the metabolic mechanism remain relatively unknown.Therefore,residual GA has always been a major health risk consideration for animal-derived medical devices.In this study,extracts of three biopatches were tested via the GA determination test and mouse lymphoma assay(MLA).The results showed that dissolved GA was a potential mutagen,which could induce significant cytotoxic and mutagenic effects in mouse lymphoma cells.These toxic reactions were relieved by the S9 metabolic activation(MA)system.Furthermore,we confirmed that GA concentration decreased and glutaric acid was generated during the catalytic process.We revealed GA could be oxidized via cytochrome P450 which was the main metabolic factor of S9.We found that even though GA was possibly responsible for positive reactions of animal-derived biomaterials’biocompatibility evaluation,it may not represent the real situation occurring in human bodies,owing to the presence of various detoxification mechanisms including the S9 system.Overall,in order to achieve a general balance between risk management and practical application,rational decisions based on comprehensive analyses must be considered. | Jianfeng Shi Huan Lian Yuanli Huang Danmei Zhao Han Wang Chunren Wang Jingli Li Linnan Ke | 2020 | Regenerative Biomaterials2020,7,6: | 1 |
