1Plant abiotic stress response and nutrient use efficiency显示文摘Abiotic stresses and soil nutrient limitations are major environmental conditions that reduce plant growth,productivity and quality.Plants have evolved mechanisms to perceive these environmental challenges,transmit the stress signals within cells as well as between cells and tissues,and make appropriate adjustments in their growth and development in order to survive and reproduce.In recent years,significant progress has been made on many fronts of the stress signaling research,particularly in understanding the downstream signaling events that culminate at the activation of stress-and nutrient limitation-responsive genes,cellular ion homeostasis,and growth adjustment.However,the revelation of the early events of stress signaling,particularly the identification of primary stress sensors,still lags behind.In this review,we summarize recent work on the genetic and molecular mechanisms of plant abiotic stress and nutrient limitation sensing and signaling and discuss new directions for future studies.Zhizhong Gong Liming Xiong Huazhong Shi Shuhua Yang Luis R.Herrera-Estrella Guohua Xu Dai-Yin Chao Jingrui Li Peng-Yun Wang Feng Qin Jigang Li Yanglin Ding Yiting Shi Yu Wang Yongqing Yang Yan Guo Jian-Kang Zhu 2020Science China(Life Sciences)2020,63,5:94

3Insights into the regulation of C-repeat binding factors in plant cold signaling显示文摘Cold temperatures, a major abiotic stress,threaten the growth and development of plants, worldwide. To cope with this adverse environmental cue, plants from temperate climates have evolved an array of sophisticated mechanisms to acclimate to cold periods,increasing their ability to tolerate freezing stress. Over the last decade, significant progress has been made in determining the molecular mechanisms underpinning cold acclimation, including following the identification of several pivotal components, including candidates for cold sensors, protein kinases, and transcription factors. With these developments, we have a better understanding of the CBF-dependent cold-signaling pathway. In this review,we summarize recent progress made in elucidating the cold-signaling pathways, especially the C-repeat binding factor-dependent pathway, and describe the regulatory function of the crucial components of plant cold signaling.We also discuss the unsolved questions that should be the focus of future work.Jingyan Liu Yiting Shi Shuhua Yang 2018Journal of Integrative Plant Biology2018,60,9:36
4Molecular Regulation of Plant Responses to Environmental Temperatures显示文摘Temperature is a key factor governing the growth and development,distribution,and seasonal behavior of plants.The entireplant life cycle is affected by environmental temperatures.Plants grow rapidly and exhibit specific changes in morphology under mild average temperature conditions,a response termed thermomorphogenesis.When exposed to chilling or moist chilling low temperatures,flowering or seed germination is accelerated in some plant species;these processes are known as vernalization and cold stratification,respectively.Interestingly,once many temperate plants are exposed to chilling temperatures for some time,they can acquire the ability to resist freezing stress,a process termed cold acclimation.In the face of global climate change,heat stress has emerged as a frequent challenge,which adversely affects plant growth and development.In this review,we summarize and discuss recent progress in dissecting them olecular mechanism sregulating plant thermomorphogenesis,vernalization,and responses to extreme temperatures.We also discuss the remaining issues that are crucial for understanding the interactions between plants and temperature.Yanglin Ding Yiting Shi Shuhua Yang 2020Molecular Plant2020,13,4:40
5The Antagonistic Action of Abscisic Acid and Cytokinin Signaling Mediates Drought Stress Response in Arabidopsis显示文摘Xiaozhen Huang Lingyan Hou Jingjing Meng Huiwen You Zhen Li Zhizhong Gong Shuhua Yang Yiting Shi 2018Molecular Plant2018,11,7:15
6Cold-Induced CBF–PIF3 Interaction Enhances Freezing Tolerance by Stabilizing the phyB Thermosensor in Arabidopsis显示文摘Growth inhibition and cold-acclimation strategies help plants withstand cold stress,which adversely affects growth and survival.PHYTOCHROME B(phyB)regulates plant growth through perceiving both light and ambient temperature signals.However,the mechanism by which phyB mediates the plant response to cold stress remains elusive.Here,we show that the key transcription factors mediating cold acclimation,C-REPEAT BINDING FACTORs(CBFs),interact with PHYTOCHROME-INTERACTING FACTOR 3(PIF3)under cold stress,thus attenuating the mutually assured destruction of PIF3–phyB.Cold-stabilized phyB acts downstream of CBFs to positively regulate freezing tolerance by modulating the expression of stress-responsive and growth-related genes.Consistent with this,phyB mutants exhibited a freezing-sensitive phenotype,whereas phyB-overexpression transgenic plants displayed enhanced freezing tolerance.Further analysis showed that the PIF1,PIF4,and PIF5 proteins,all of which negatively regulate plant freezing tolerance,were destabilized by cold stress in a phytochrome-dependent manner.Collectively,our study reveals that CBFs–PIF3–phyB serves as an important regulatory module for modulating plant response to cold stress.Bochen Jiang Yiting Shi Yue Peng Yuxin Jia Yan Yan Xiaojing Dong Hui Li Jie Dong Jigang Li Zhizhong Gong Michael F.Thomashow Shuhua Yang 2020Molecular Plant2020,13,6:13

8Biosynthesis of Triacylglycerol Molecules with a Tailored PUFA Profile in Industrial Microalgae显示文摘The composition of polyun saturated fatty acids (PUFAs) in triacylglycerols (TAGs) is key to health ben efits and for oil applications, yet the underlying genetic mechanism remains poorly understood. In this study, by in si Iico, ex vivo, and in vivo profili ng of type-2 diacylglycerol acyltransferases (DGAT2s) in Nannochloropsis oceanica we revealed two novel PUFA-preferring enzymes that discriminate individual PUFA species in TAG assembly, with NoDGAT2J for linoleic acid (LA) and NoDGAT2K for eicosapentaenoic acid (EPA). The LA and EPA composition of TAG molecules is mediated in vivo via the functional partitioning between NoDGAT2J and 2K, both of which are localized in the chloroplast envelope. By modulating transcript abundance of the DGAT2s, an N. oceanica strain bank was created, where proportions of LA and EPA in TAG vary by 18.7-fold (between 0.21% and 3.92% dry weight) and 34.7-fold (between 0.09% and 3.12% dry weight), respective!y. These findings lay the foundation for producing designer TAG molecules with tailored health benefits or for biofuel applications in industrial microalgae and higher-plant crops.Yi Xin Chen Shen Yiting She Hong Chen Cong Wang Li Wei Kangsup Yoon Danxiang Han Qiang Hu Jian Xu 2019Molecular Plant2019,12,4:10
9Clinical Application of Chromosome Microarray Analysis in Han Chinese Children with Neurodevelopmental Disorders显示文摘Chromosome microarray analysis(CMA) is a cost-effective molecular cytogenetic technique that has been used as a first-line diagnostic test in neurodevelopmental disorders in the USA since 2011. The impact of CMA results on clinical practice in China is not yet well studied, so we aimed to better evaluate this phenomenon.We analyzed the CMA results from 434 patients in our clinic, and characterized their molecular diagnoses, clinical features, and follow-up clinical actions based on these results. The overall diagnostic yield for our patients was 13.6%(59 out of 434). This gave a detection rate of 14.7%for developmental delay/intellectual disability(DD/ID,38/259) and 12% for autism spectrum disorders(ASDs,21/175). Thirty-three recurrent(n≥2) variants were found, distributed at six chromosomal loci involving known chromosome syndromes(such as DiGeorge, Williams Beuren, and Angelman/Prader-Willi syndromes).The spectrum of positive copy number variants in our study was comparable to that reported in Caucasian populations, but with specific characteristics. Parental origin tests indicated an effect involving a significant maternal transmission bias to sons. The majority of patients with positive results(94.9%) had benefits, allowing earlier diagnosis(36/59), prioritized full clinical management(28/59), medication changes(7/59), a changed prognosis(30/59), and prenatal genetic counseling(15/59). Our results provide information on de novo mutations in Chinese children with DD/ID and/or ASDs. Our data showed that microarray testing provides immediate clinical utility for patients. It is expected that the personalized medical care of children with developmental disabilities will lead to improved outcomes in long-term developmental potential.We advocate using the diagnostic yield of clinically actionable results to evaluate CMA as it provides information of both clinical validity and clinical utility.Mingyu Xu Yiting Ji Ting Zhang Xiaodong Jiang Yun Fan Juan Geng Fei Li 2018Neuroscience Bulletin2018,34,6:8

11Adenomyosis-derived extracellular vesicles endow endometrial epithelial cells with an invasive phenotype through epithelial-mesenchymal transition显示文摘Extracellular vesicles from highly metastatic tumor cells have been shown to mediate epithelial-mesenchymal transition(EMT)-related events in recipient cells.In endometrial epithelial cells,EMT processes are known to be involved in the development of adenomyosis.We aimed to investigate whether adenomyosis-derived extracellular vesicles(AMEVs)are able to induce an EMT process in endometrial epithelial cells.In this study,AMEVs were isolated from patients with adenomyosis and characterized by transmission electron microscopy,Western blot,and nanoparticle tracking.Primary endometrial epithelial cells(EECs)were derived from normal endometrium tissues from patients with leiomyoma and co-cultured with AMEVs in vitro.AMEV uptake was examined by fluorescence confocal microscopy.The invasion of EECs was confirmed by Transwell assay.Immunohistochemistry,Western blot,and qRT-PCR were performed on EECs to illustrate the expression levels of cytokeratin 19,E-cadherin,vimentin,and zinc finger E-boxbinding homeobox 1(ZEB1).The results indicated that the cellular fluorescence intensity gradually increased after 48 h of co-culture,but decreased after 72 h.After co-culturing with AMEVs for 72 h,EECs expressed significantly lower levels of cytokeratin 19 and E-cadherin,and significantly higher levels of vimentin and ZEB1.Together these results demonstrated that AMEVs induce an EMT process and enhance the invasion of EECs.These changes may contribute to the pathogenesis and progression of adenomyosis.Dayong Chen Hai Qiao Yiting Wang Ling Zhou Na Yin Liaoqiong Fang Zhibiao Wang 2020Genes & Diseases2020,7,4:8

13One SNP in COLD1 Determines Cold Tolerance during Rice Domestication显示文摘With the effect of global climate change on grain yield and distribution of crops,to understand how plant responds to extreme temperature stress is becoming crucial.Plants have evolved fine-tuned mechanisms in response to a wide variety of environmental stresses.During rice(Oryza sativa L.)domestication,two main genotypes are bred andYiting Shi Zhizhong Gong 2015Journal of Genetics and Genomics2015,42,4:7
14Salmonella flagella confer anti-tumor immunological effect via activating Flagellin/TLR5 signalling within tumor microenvironment显示文摘Salmonella:mediated cancer therapy has achieved remarkable anti-tumor effects in experimental animal models,but the detailed mechanism remains unsolved.In this report,the active involvement of the host immune response in this process was confirmed by comparing the tumor-suppressive effects of Salmonella in immunocompetent and immunodeficient mice bearing melanoma allografts.Since flagella are key inducers of the host immune response during bacterial infection,flagella were genetically disrupted to analyse their involvement in Salmonella-mediated cancer therapy.The results showed that flagellum-deficient strains failed to induce significant anti-tumor effects,even when more bacteria were administered to offset the difference in invasion efficiency.Flagella mainly activate immune cells via Flagellin/Toll-like receptor 5(TLR5)signalling pathway.Indeed,we showed that exogenous activation of TLR5 signalling by recombinant Flagellin and exogenous expression of TLR5 both enhanced the therapeutic efficacy of flagellum-deficient Salmonella against melanoma.Our study highlighted the therapeutic value of the interaction between Salmonella and the host immune response through Flagellin/TLR5 signalling pathway during Salmonella-mediated cancer therapy,thereby suggesting the potential application of TLR5 agonists in the cancer immune therapy.Jianxiang Chen Yiting Qiao Guo Chen Cunjie Chang Heng Dong Bo Tang Xiawei Cheng Xiufeng Liu Zichun Hua 2021Acta Pharmaceutica Sinica B2021,11,10:6
15Gap-surface plasmon metasurfaces for linear-polarization conversion, focusing,and beam splitting显示文摘Gap-surface plasmon(GSP)metasurfaces have attracted progressively increasing attention due to their planar configurations,ease of fabrication,and unprecedented capabilities in manipulating the reflected fields that enable integrating diverse bulk-optic-based optical components into a single ultrathin flat element.In this work,we design and experimentally demonstrate multifunctional metalenses that perform simultaneous linear-polarization conversion,focusing,and beam splitting,thereby reproducing the combined functionalities of conventional halfwave plates,parabolic reflectors,and beam splitters.The fabricated single-focal metalens incorporates properly configured distinct half-wave-plate-like GSP meta-atoms and exhibits good performance under linearly polarized incidence in terms of orthogonal linear-polarization conversion(>75%)and focusing(overall efficiency>22%)in the wavelength spectrum ranging from 800 to 950 nm.To further extend the combined functionalities,we demonstrate a dual-focal metalens that splits and focuses a linearly polarized incident beam into two focal spots while maintaining the capability of orthogonal linear-polarization conversion.Furthermore,the power distribution between two split beams can readily be controlled by judiciously positioning the incident beam.The demonstrated multifunctional GSP-based metalenses mimic the combined functionalities of a sequence of discrete bulk optical components,thereby eliminating the need for their mutual alignment and opening new perspectives in the development of ultracompact and integrated photonic devices.FEI DING YITING CHEN SERGEY IBOZHEVOLNYI 2020Photonics Research2020,8,5:5
16Survey on deep learning for pulmonary medical imaging显示文摘As a promising method in artificial intelligence,deep learning has been proven successful in several domains ranging from acoustics and images to natural language processing.With medical imaging becoming an important part of disease screening and diagnosis,deep learning-based approaches have emerged as powerful techniques in medical image areas.In this process,feature representations are learned directly and automatically from data,leading to remarkable breakthroughs in the medical field.Deep learning has been widely applied in medical imaging for improved image analysis.This paper reviews the major deep learning techniques in this time of rapid evolution and summarizes some of its key contributions and state-of-the-art outcomes.The topics include classification,detection,and segmentation tasks on medical image analysis with respect to pulmonary medical images,datasets,and benchmarks.A comprehensive overview of these methods implemented on various lung diseases consisting of pulmonary nodule diseases,pulmonary embolism,pneumonia,and interstitial lung disease is also provided.Lastly,the application of deep learning techniques to the medical image and an analysis of their future challenges and potential directions are discussed.Jiechao Ma Yang Song Xi Tian Yiting Hua Rongguo Zhang Jianlin Wu 2020Frontiers of Medicine2020,14,4:5
173D printing of high-performance micro-supercapacitors with patterned exfoliated graphene/carbon nanotube/silver nanowire electrodes显示文摘Micro-supercapacitors(MSCs)show great potential as on-chip energy storage devices for portable electronics.The major flaw of thin-film MSCs is their low energy density.To improve the energy density,thicker electrodes are required.However,the fabrication of MSCs with thick electrodes remains a challenge.In this work,a novel 3D printing method is employed to fabricate high-performance MSCs with interdigitated exfoliated graphene(EG)/carbon nanotube(CNT)/silver nanowire(Ag NW)electrodes.The nanowelding of Ag NW junction plays a critical role in the realization of 3D printing.To enhance the electrochemical performances of EG,phosphorus atoms are incorporated into the carbon framework with 1.7 at%.The areal capacitance of the 3D printed MSC is 21.6 mF cm^(-2)at a scan rate of 0.01 V s^(-1).The areal energy density of the MSC ranges from 0.5 to 2μWh cm^(-2)with a maximum power density of 2.5 mW cm^(-2).LIU Lang LU JunYong LONG XinLin ZHOU Ren LIU YingQuan WU YiTing YAN KangWei 2021Science China(Technological Sciences)2021,64,5:4
18Shear-responsive boundary-lubricated hydrogels attenuate osteoarthritis显示文摘Lipid-based boundary layers formed on liposome-containing hydrogels can facilitate lubrication.However,these boundary layers can be damaged by shear,resulting in decreased lubrication.Here,a shear-responsive boundary-lubricated drug-loaded hydrogel is created by incorporating celecoxib(CLX)-loaded liposomes within dynamic covalent bond-based hyaluronic acid(HA)hydrogels(CLX@Lipo@HA-gel).The dynamic cross-linked network enables the hydrogel to get restructured in response to shear,and the HA matrix allows the accumulation of internal liposome microreservoirs on the sliding surfaces,which results in the formation of boundary layers to provide stable lubrication.Moreover,hydration shells formed surrounding the hydrogel can retard the degradation process,thus helping in sustaining lubrication.Furthermore,in vitro and in vivo experiments found that CLX@Lipo@HA-gels can maintain anabolic-catabolic balance,alleviate cartilage wear,and attenuate osteoarthritis progression by delivering CLX and shear-responsive boundary lubrication.Overall,CLX@Lipo@HA-gels can serve as shear-responsive boundary lubricants and drug-delivery vehicles to alleviate friction-related diseases like osteoarthritis.Yiting Lei Xingkuan Wang Junyi Liao Jieliang Shen Yuling Li Zhengwei Cai Ning Hu Xiaoji Luo Wenguo Cui Wei Huang 2022Bioactive Materials2022,7,10:4
19Terrain relief periods of loess landforms based on terrain profiles of the Loess Plateau in northern Shaanxi Province,China显示文摘The Loess Plateau is densely covered by numerous types of gullies which represent different soil erosion intensities.Therefore,research on topographic variation features of the loess gullies is of great significance to environmental protection and ecological management.Using a5 m digital elevation model and data from a national geographic database,this paper studies different topographical areas of the Loess Plateau,including Shenmu,Suide,Yanchuan,Ganquan,Yijun,and Chunhua,to derive representative gully terrain profile data of the sampled areas.First,the profile data are standardized in MATLAB and then decomposed using the ensemble empirical mode decomposition method.Then,a significance test is performed on the results;the test confidence is 95% to 99%.The most reliable decomposition component is then used to calculate the relief period and size of the gullies.The results showed that relief periods of the Chunhua,Shenmu,Yijun,Yuanchuan,Ganquan,and Suide gullies are 1110.14 m,1096.85 m,1002.49 m,523.48 m,498.12 m,and 270.83 m,respectively.In terms of gully size,the loess landforms are sorted as loess fragmented tableland,aeolian and dune,loess tableland,loess ridge,loess hill and loess ridge,and loess hill,in descending order.Taken together,the gully terrain features of the sample areas and the results of the study are approximately consistent with the actual terrain profiles.Thus,we conclude that ensemble empirical mode decomposition is a reliable method for the study of the relief and topography of loess gullies.Jianjun CAO Guoan TANG Xuan FANG Jilong LI Yongjuan LIU Yiting ZHANG Ying ZHU Fayuan LI 2019Frontiers of Earth Science2019,13,2:4
20Integration of light and temperature signaling pathways in plants显示文摘As two of the most important environmental factors,light and temperature regulate almost all aspects of plant growth and development.Under natural conditions,light is accompanied by warm temperatures and darkness by cooler temperatures,suggesting that light and temperature are tightly associated signals for plants.Indeed,accumulating evidence shows that plants have evolved a wide range of mechanisms to simultaneously perceive and respond to dynamic changes in light and temperature.Notably,the photoreceptor phytochrome B(phy B)was recently shown to function as a thermosensor,thus reinforcing the notion that light and temperature signaling pathways are tightly associated in plants.In this review,we summarize and discuss the current understanding of the molecular mechanisms integrating light and temperature signaling pathways in plants,with the emphasis on recent progress in temperature sensing,light control of plant freezing tolerance,and thermomorphogenesis.We also discuss the questions that are crucial for a further understanding of the interactions between light and temperature signaling pathways in plants.Lijuan Qi Yiting Shi William Terzaghi Shuhua Yang Jigang Li 2022Journal of Integrative Plant Biology2022,64,2:4
