2The genome of Medicago polymorpha provides insights into its edibility and nutritional value as a vegetable and forage legume显示文摘Medicago polymorpha is a nutritious and palatable forage and vegetable plant that also fixes nitrogen.Here,we reveal the chromosome-scale genome sequence of M.polymorpha using an integrated approach including Illumina,PacBio and Hi-C technologies.We combined PacBio full-length RNA-seq,metabolomic analysis,structural anatomy analysis and related physiological indexes to elucidate the important agronomic traits of M.polymorpha for forage and vegetable usage.The assembled M.polymorpha genome consisted of 457.53Mb with a long scaffold N50 of 57.72Mb,and 92.92%(441.83Mb)of the assembly was assigned to seven pseudochromosomes.Comparative genomic analysis revealed that expansion and contraction of the photosynthesis and lignin biosynthetic gene families,respectively,led to enhancement of nutritious compounds and reduced lignin biosynthesis in M.polymorpha.In addition,we found that several positively selected nitrogen metabolism-related genes were responsible for crude protein biosynthesis.Notably,the metabolomic results revealed that a large number of flavonoids,vitamins,alkaloids,and terpenoids were enriched in M.polymorpha.These results imply that the decreased lignin content but relatively high nutrient content of M.polymorpha enhance its edibility and nutritional value as a forage and vegetable.Our genomic data provide a genetic basis that will accelerate functional genomic and breeding research on M.polymorpha as well as other Medicago and legume plants.Jiawen Cui Zhaogeng Lu Tianyi Wang Gang Chen Salma Mostafa Hailong Ren Sian Liu Chunxiang Fu Li Wang Yingfang Zhu Jinkai Lu Xiang Chen Zhenwu Wei Biao Jin 2021Horticulture Research2021,8,1:6
3Crystal structure of the ubiquitin-like domain of human TBK1显示文摘TANK-binding kinase 1(TBK1)is an important enzyme in the regulation of cellular antiviral effects.TBK1 regulates the activity of the interferon regulatory factors IRF3 and IRF7,thereby playing a key role in type I interferon(IFN)signaling pathways.The structure of TBK1 consists of an N-terminal kinase domain,a middle ubiquitin-like domain(ULD),and a C-terminal elongated helical domain.It has been reported that the ULD of TBK1 regulates kinase activity,playing an important role in signaling and mediating interactions with other molecules in the IFN pathway.In this study,we present the crystal structure of the ULD of human TBK1 and identify several con-served residues by multiple sequence alignment.We found that a hydrophobic patch in TBK1,containing residues Leu316,Ile353,and Val382,corresponding to the“Ile44 hydrophobic patch”observed in ubiquitin,was conserved in TBK1,IκB kinase epsilon(IKKε/IKKi),IκB kinase alpha(IKKα),and IκB kinase beta(IKKβ).In com-parison with the structure of the IKKβULD domain of Xenopus laevis,we speculate that the Ile44 hydrophobic patch of TBK1 is present in an intramolecular binding surface between ULD and the C-terminal elongated heli-ces.The varying surface charge distributions in the ULD domains of IKK and IKK-related kinases may be relevant to their specificity for specific partners.Jian Li Jun Li Andrea Miyahira Jian Sun Yingfang Liu Genhong Cheng Huanhuan Liang 2012Protein & Cell2012,3,5:5

5A novel selective autophagy receptor,CCDC50,delivers K63 polyubiquitination-activated RIG-I/MDA5 for degradation during viral infection显示文摘Autophagy is a con served process that delivers cytosolic substa nces to the lysosome for degradatio n,but its direct role in the regulation of antiviral inn ate immu nity remains poorly un derstood.Here,through high-throughput screeni ng,we discovered that CCDC50 functions as a previously unknown autophagy receptor that negatively regulates the type I interferon(IFN)signaling pathway initiated by RIG-I-like receptors(RLRs),the sensors for RNA viruses.The expression of CCDC50 is enhanced by viral infection,and CCDC50 specifically recognizes K63-polyubiquitinated RLRs,thus delivering the activated RIG-I/MDA5 for autophagic degradation.The associatio n of CCDC50 with phagophore membrane protei n LC3 is con firmed by crystal structure analysis.In contrast to other known autophagic cargo receptors that associate with either the LIR-docking site(LDS)or the UIMdocking site(UDS)of LC3,CCDC50 can bind to both LDS and UDS,representing a new type of cargo receptor.In mouse models with RNA virus infection,CCDC50 deficiency reduces the autophagic degradation of RIG-I/MDA5 and promotes type I IFN responses,resulting in enhaneed viral resistance and improved survival rates.These results reveal a new link between autophagy and antiviral innate immune resp on ses and provide additional in sights into the regulatory mecha nisms of RLR-mediated antiviral signaling.Panpan Hou Kongxiang Yang Penghui Jia Lan Liu Yuxin Lin Zibo Li Jun Li Shuliang Chen Shuting Guo Ji'An Pan Junyu Wu Hong Peng Weijie Zeng Chunmei Li Yingfang Liu Deyin Guo 2021Cell Research2021,31,1:5
6Cryo-self-assembled silk fibroin sponge as a biodegradable platform for enzyme-responsive delivery of exosomes显示文摘Although advances in protein assembly preparation have provided a new platform for drug delivery during tissue engineering,achieving long-term controlled exosome delivery remains a significant challenge.Diffusion-dominated exosome release using protein hydrogels results in burst release of exosomes.Here,a fibroin-based cryo-sponge was developed to provide controlled exosome release.Fibroin chains can self-assemble into silk I structures under ice-cold conditions when annealed above the glass transition temperature.Exosome release is enzyme-responsive,with rates primarily determined by enzymatic degradation of the scaffolds.In vivo experiments have demonstrated that exosomes remain in undigested sponge material for two months,superior to their retention in fibrin glue,a commonly used biomaterial in clinical practice.Fibroin cryo-sponges were implanted subcutaneously in nude mice.The exosome-containing sponge group exhibited better neovascularization and tissue ingrowth effects,demonstrating the efficacy of this exosome-encapsulating strategy by realizing sustained release and maintaining exosome bioactivity.These silk fibroin cryo-sponges containing exosomes provide a new platform for future studies of exosome therapy.Muyang Sun Qi Li Huilei Yu Jin Cheng Nier Wu Weili Shi Fengyuan Zhao Zhenxing Shao Qingyang Meng Haifeng Chen Xiaoqing Hu Yingfang Ao 2022Bioactive Materials2022,7,2:4

8The LRXs-RALFs-FER module controls plant growth and salt stress responses by modulating multiple plant hormones显示文摘Salt stress is a major environmental factor limiting plant growth and productivity.We recently discovered an important new salt tolerance pathway,where the cell wall leucine-rich repeat extensins LRX3/4/5,the RAPID ALKALINIZATION FACTOR(RALF)peptides RALF22/23 and receptor-like kinase FERONIA(FER)function as a module to simultaneously regulate plant growth and salt stress tolerance.However,the intracellular signaling pathways that are regulated by the extracellular LRX3/4/5-RALF22/23-FER module to coordinate growth,cell wall integrity and salt stress responses are still unknown.Here,we report that the LRX3/4/5-RALF22/23-FER module negatively regulates the levels of jasmonic acid(JA),salicylic acid(SA)and abscisic acid(ABA).Blocking JA pathway rescues the dwarf phenotype of the lrx345 and fer-4mutants,while disruption of ABA biosynthesis suppresses the salt-hypersensitivity of these mutants.Many salt stress-responsive genes display abnormal expression patterns in the lrx345 and fer-4 mutants,as well as in the wild type plants treated with epigallocatechin gallate(EGCG),an inhibitor of pectin methylesterases,suggesting cell wall integrity as a critical factor that determines the expression pattern of stress-responsive genes.Production of reactive oxygen species(ROS)is constitutively increased in the lrx345 and fer-4mutants,and inhibition of ROS accumulation suppresses the salt-hypersensitivity of these mutants.Together,our work provides strong evidence that the LRX3/4/5-RALF22/23-FER module controls plant growth and salt stress responses by regulating hormonal homeostasis and ROS accumulation.Chunzhao Zhao Wei Jiang Omar Zayed Xin Liu Kai Tang Wenfeng Nie Yali Li Shaojun Xie Yuan Li Tiandan Long Linlin Liu Yingfang Zhu Yang Zhao Jian-Kang Zhu 2021National Science Review2021,8,1:3
9The epigallocatechin gallate derivative Y_6 reverses drug resistance mediated by the ABCB1 transporter both in vitro and in vivo显示文摘Previously, we reported that Y_6, a new epigallocatechin gallate derivative, is efficacious in reversing doxorubicin(DOX)–mediated resistance in hepatocellular carcinoma BEL-7404/DOX cells. In this study, we evaluated the efficacy of Y_6 in reversing drug resistance both in vitro and in vivo by determining its effect on the adenosine triphosphate-binding cassette protein B1 transporter(ABCB1 or P-glycoprotein, P-gp). Our results showed that Y_6 significantly sensitized cells overexpressing the ABCB1 transporter to anticancer drugs that are ABCB1 substrates. Y_6 significantly stimulated the adenosine triphosphatase activity of ABCB1. Furthermore, Y_6 exhibited a higher docking score as compared with epigallocatechin gallate inside the transmembrane domain of ABCB1. In addition, in the nude mousetumor xenograft model, Y_6(110 mg/kg, intragastric administration), in combination with doxorubicin(2 mg/kg, intraperitoneal injection), significantly inhibited the growth of BEL-7404/DOX cell xenograft tumors, compared to equivalent epigallocatechin gallate. In conclusion, Y_6 significantly reversed ABCB1-mediated multidrug resistance and its mechanisms of action may result from its competitive inhibition of the ABCB1 drug efflux function.Yan Wen Ruiqiang Zhao Pranav Gupta Yingfang Fan Yunkai Zhang Zhenguang Huang Xiaohui Li Yuangang Su Lijuan Liao Yu-An Xie Donghua Yang Zhe-Sheng Chen Gang Liang 2019Acta Pharmaceutica Sinica B2019,9,2:3
10Extraterrestrial artificial photosynthetic materials for in-situ resource utilization显示文摘Aerospace milestones in human history,including returning to the moon and manned Martian missions,have been implemented in recent years.Space exploration has become one of the global common goals,and to ensure the survival and development of human beings in the extraterrestrial extreme environment has been becoming the basic ability and technology of manned space exploration.For the purpose of fulfilling the goal of extraterrestrial survival,researchers in Nanjing University and the China Academy of Space Technology proposed extraterrestrial artificial photosynthesis(EAP)technology.By simulating the natural photosynthesis of green plants on the Earth,EAP converts CO_(2)/H_(2)O into fuel and O_(2)in an in-situ,accelerated and controllable manner by using waste CO_(2)in the confined space of spacecraft,or abundant CO_(2)resources in extraterrestrial celestial environments,e.g.Mars.Thus,the material loading of manned spacecraft can be greatly reduced to support affordable and sustainable deep space exploration.In this paper,EAP technology is compared with existing methods of converting CO_(2)/H_(2)O into fuel and O_(2)in the aerospace field,especially the Sabatier method and Bosch reduction method.The research progress of possible EAP materials for in-situ utilization of extraterrestrial resources are also discussed in depth.Finally,this review lists the challenges that the EAP process may encounter,which need to be focused on for future implementation and application.We expect to deepen the understanding of artificial photosynthetic materials and technologies,and aim to strongly support the development of manned spaceflight.Liuqing Yang Ce Zhang Xiwen Yu Yingfang Yao Zhaosheng Li Congping Wu Wei Yao Zhigang Zou 2021National Science Review2021,8,8:3
11Surpassing electrocatalytic limit of earth-abundant Fe^(4+)embedded in N-doped graphene for(photo)electrocatalytic water oxidation显示文摘Developing highly active,cost-effective,and environmental friendly oxygen evolution reaction(OER)electrocatalysts facilitates various(photo)electrochemical processes.In this work,Fe3N nanoparticles encapsulated into N-doped graphene nanoshells(Fe_(3)N@NG)as OER electrocatalysts in alkaline media were reported.Both the experimental and theoretical comparison between Fe_(3) N@NG and Fe_(3)N/NG,specifically including in situ Mossbauer analyses,demonstrated that the NG nanoshells improved interfacial electron transfer process from Fe_(3)N to NG to form high-valence Fe^(4+)ions(Fe^(4+)@NG),thus modifying electronic properties of the outer NG shells and subsequently electron transfer from oxygen intermediate to NG nanoshells for OER catalytic process.Meanwhile,the NG nanoshells also protected Fe-based cores from forming OER inactive and insulated Fe_(2)O_(3),leading to high OER stability.As a result,the as-formed Fe^(4+)@NG shows one of the highest electrocatalytic efficiency among reported Fe-based OER electrocatalysts,which can as well highly improve the photoelectrochemical water oxidation when used as the cocatalysts for the Fe_(2)O_(3) nanoarray photoanode.Wenjia Xue Feng Cheng Menglu Li Wenjian Hu Congping Wu Bing Wang Kuowei Liao ZhenTao Yu Yingfang Yao Wenjun Luo Zhigang Zou 2021Journal of Energy Chemistry2021,30,3:2
12A Retrospective Study of Treatment Efficacy of 65 Children with Ametroic Amblyopia显示文摘Purpose: To investigate relationship between treatment efficacy and the severity of ametropic amblyopia, the type of anisometropia and patient age. Methods:A total of 65 children with ametropic amblyopia undergoing clinical treatment in the ophthalmology department of Shaoguan Hygienic Hospital of Women and Children between June 2005 and November 2011 were enrolled in this study. The treatment efficacy for those subjects with different severities of ametropic amblyopia, types of anisometropia and ages was recorded. Results: The near-recovery/recovery rate, improvement rate and ineffectiveness rate were 70.8%, 16.9% and 12.3%, respectively. The recovery rates in mild-, moderate- and severe amblyopia groups were 97.1%, 61.1% and 8.3% respectively (P<0.05)..The recovery rate for patients with hyperopic-, astigmatic- and myopic anisometropia were 75.8%, 78.3% and 33.3% respectively. The recovery rates did not differ between hyperopic- and astigmatic- anisometropia children(P>0.05), whereas a statistically significant difference was noted between myopic children compared with their hyperopic and myopic-anisometropia counterparts (all P<0.05). The recovery rate for patients aged 3 to 6 years was 86.8% and 48.1% for those aged between 7 and 10 years (P<0.05). Conclusion: The treatment efficacy in ametropic amblyopia is associated with the severity of amblyopia, type of anisometropia and patient's age. Older patients with more severe amblyopia had poorer treatment efficacy. The efficacy in patients with hyperopic and astigmatic anisometropia was better than that for myopic anisometropia subjects.Yuxiang Zhang Lihua Huang Changyang Cao Yingfang Li 2012Eye Science2012,27,2:2

18Mediator tail module subunits MED16 and MED25 differentially regulate abscisic acid signaling in Arabidopsis显示文摘MED25 has been implicated as a negative regulator of the abscisic acid(ABA)signaling pathway.However,it is unclear whether other Mediator subunits could associate with MED25 to participate in the ABA response.Here,we used affinity purification followed by mass spectrometry to uncover Mediator subunits that associate with MED25 in transgenic plants.We found that at least26 Mediator subunits,belonging to the head,middle,tail,and CDK8 kinase modules,were copurified with MED25 in vivo.Interestingly,the tail module subunit MED16 was identified to associate with MED25 under both mock and ABA treatments.We further showed that the disruption of MED16 led to reduced ABA sensitivity compared to the wild type.Transcriptomic analysis revealedthattheexpressionofseveral ABA-responsive genes was significantly lower in med16 than those in wild type.Furthermore,we discovered that MED16 may possibly compete with MED25 to interact with the key transcription factor ABA INSENSITIVE 5(ABI5)to positively regulate ABA signaling.Consistently,med16 and med25 mutants displayed opposite phenotypes in ABA response,cuticle permeability,and differential ABI5-mediated EM1 and EM6 expression.Together,our data indicate that MED16 and MED25 differentially regulate ABA signaling byantagonisticallyaffectingABI5-mediated transcription in Arabidopsis.Pengcheng Guo Leelyn Chong Fangming Wu Chuan-Chih Hsu Chuanyou Li Jian-Kang Zhu Yingfang Zhu 2021Journal of Integrative Plant Biology2021,63,4:1
