| 2 | Increased activity of MdFRK2, a high-affinity fructokinase, leads to upregulation of sorbitol metabolism and downregulation of sucrose metabolism in apple leaves显示文摘To investigate the functions of fructokinase(FRK)in apple(Malus domestica)carbohydrate metabolism,we cloned the coding sequences of MdFRK1 and MdFRK2 from the‘Royal Gala’apple.The results showed that MdFRK2 expression was extremely high in shoot tips and young fruit.Analyses of heterologously expressed proteins revealed that MdFRK2 had a higher affinity for fructose than did MdFRK1,with Km values of 0.1 and 0.62 mM for MdFRK2 and MdFRK1,respectively.The two proteins,however,exhibited similar Vmax values when their activities were significantly inhibited by high concentrations of fructose.MdFRK2 ectopic expression was associated with a general decrease in fructose concentration in transgenic lines.In leaves,increased FRK activity similarly resulted in reduced concentrations of glucose and sucrose but no alterations in sorbitol concentration.When compared with those in the untransformed control,genes involved in sorbitol synthesis(A6PR)and the degradation pathway(SDH1/2)were significantly upregulated in transgenic lines,whereas those involved in sucrose synthesis(SPS1)and other degradation processes(SUSY4,NINV1/2,and HxK2)were downregulated.The activity of enzymes participating in carbohydrate metabolism was proportional to the level of gene expression.However,the growth performance and photosynthetic efficiency did not differ between the transgenic and wild-type plants.These results provide new genetic evidence to support the view that FRK plays roles in regulating sugar and sorbitol metabolism in Rosaceae plants. | Jingjing Yang Lingcheng Zhu Weifang Cui Chen Zhang Dongxia Li Baiquan Ma Lailiang Cheng Yong-Ling Ruan Fengwang Ma Mingjun Li | 2018 | Horticulture Research2018,5,1: | 9 |
| 3 | A Prototype Regional GSI-based EnKF-Variational Hybrid Data Assimilation System for the Rapid Refresh Forecasting System:Dual-Resolution Implementation and Testing Results显示文摘A dual-resolution(DR) version of a regional ensemble Kalman filter(EnKF)-3D ensemble variational(3DEnVar) coupled hybrid data assimilation system is implemented as a prototype for the operational Rapid Refresh forecasting system. The DR 3DEnVar system combines a high-resolution(HR) deterministic background forecast with lower-resolution(LR) EnKF ensemble perturbations used for flow-dependent background error covariance to produce a HR analysis. The computational cost is substantially reduced by running the ensemble forecasts and EnKF analyses at LR. The DR 3DEnVar system is tested with 3-h cycles over a 9-day period using a 40/13-km grid spacing combination. The HR forecasts from the DR hybrid analyses are compared with forecasts launched from HR Gridpoint Statistical Interpolation(GSI) 3D variational(3DVar)analyses, and single LR hybrid analyses interpolated to the HR grid. With the DR 3DEnVar system, a 90% weight for the ensemble covariance yields the lowest forecast errors and the DR hybrid system clearly outperforms the HR GSI 3DVar.Humidity and wind forecasts are also better than those launched from interpolated LR hybrid analyses, but the temperature forecasts are slightly worse. The humidity forecasts are improved most. For precipitation forecasts, the DR 3DEnVar always outperforms HR GSI 3DVar. It also outperforms the LR 3DEnVar, except for the initial forecast period and lower thresholds. | Yujie PAN Ming XUE Kefeng ZHU Mingjun WANG | 2018 | Advances in Atmospheric Sciences2018,35,5: | 7 |
| 4 | In-situ observation for formation and dissociation of carbon dioxide hydrate in porous media by magnetic resonance imaging显示文摘The study of formation and dissociation of CO 2 hydrate in porous media was characterized by magnetic resonance imaging (MRI) system in in situ conditions. This work simulated porous media by using glass beads of uniform size. The growth and dissociation habit of CO2 hydrate was observed under different temperature and pressure conditions. The induction time and the hydrate saturation during the growth and dissociation process in different sizes of porous media were obtained by using the MRI signal intensity. The results indicate that hydrate growth rate and the induction time are affected by the size of porous media, pressure, and degree of supercooling. There are three hydrate growth stages, i.e., initial growth stage, rapid growth stage and steady stage. In this study,the CO2 hydrate forms preferentially at the surface of vessel and then gradually grows inward. The hydrate tends to cement the glass beads together and occupies the pore gradually. As the hydrate decomposes gradually, the dissociation rate increases to the maximum and then decreases to zero. | CHENG ChuanXiao ZHAO JiaFei SONG YongChen ZHU ZiHao LIU WeiGuo ZHANG Yi YANG MingJun YU XiChong | 2013 | Science China Earth Sciences2013,56,4: | 5 |
| 5 | The integration of transcriptomic and transgenic analyses reveals the involvement of the SA response pathway in the defense of chrysanthemum against the necrotrophic fungus Alternaria sp.显示文摘Chrysanthemum morifolium cv.‘Huaihuang’has ornamental,edible,medicinal,and tea product uses.However,its field growth,yield,and quality are negatively affected by black spot disease caused by Alternaria sp.(Strain:HQJH10092301;GenBank accession number:KF688111).In this study,we transcriptionally and transgenically characterized a new cultivar,‘Huaiju 2#’(Henan Traditional Chinese Medicine Plant Cultivar identification number:2016002),which was bred from‘Huaihuang’and shows resistance to Alternaria sp.Numerous‘Huaiju 2#’plants were inoculated with Alternaria sp.for three or five days.Metabolic analysis showed increases in both salicylic acid(SA)and jasmonic acid(JA)in infected plants compared to the control.Protein activity analysis also revealed a significant increase in defense enzyme activities in infected plants.RNA-Seq of plants infected for 3 or 5 days produced a total of 58.6 GB of clean reads.Among these reads,16,550 and 13,559 differentially expressed genes(DEGs)were identified in Cm_3 dpi(sample from 3 days post-inoculation labeled as Cm_3 dpi)and Cm_5 dpi(sample from 5 days post-inoculation labeled as Cm_5 dpi),respectively,compared with their controls(Cm_0 d:a mixture samples from 0 d(before inoculation)and those treated with sterile distilled water at 3 dpi and 5 dpi).Gene annotation and cluster analysis of the DEGs revealed a variety of defense responses to Alternaria sp.infection,which were characterized by increases in resistance(R)proteins and the reactive oxygen species(ROS),Ca2+,mitogen-activated protein kinase(MAPK),and JA signaling pathways.In particular,SA signaling was highly responsive to Alternaria sp.infection.The qPCR analysis of 12 DEG candidates supported their differential expression characterized by using the RNA-Seq data.One candidate was CmNPR1(nonexpressor of pathogenesis-related gene 1),an important positive regulator of SA in systemic acquired resistance(SAR).Overexpression of CmNPR1 in‘Huaiju 2#’increased the resistance of transgenic plants to black spot.These findings indicate that the SA response pathway is likely involved in the defense of‘Huaiju 2#’against Alternaria sp.pathogens. | Xiting Zhao Lingyu Song Liwei Jiang Yuting Zhu Qinghui Gao Dandan Wang Jing Xie Meng Lv Ping Liu Mingjun Li | 2020 | Horticulture Research2020,7,1: | 3 |
| 6 | All-optical controlled-NOT logic gate achieving directional asymmetric transmission based on metasurface doublet显示文摘Optical logic gates play important roles in all-optical logic circuits,which lie at the heart of the next-generation optical computing technology.However,the intrinsic contradiction between compactness and robustness hinders the development in this field.Here,we propose a simple design principle that can possess multiple-input-output states according to the incident circular polarization and direction based on the metasurface doublet,which enables controlled-NOT logic gates in infrared region.Therefore,the directional asymmetric electromagnetic transmission can be achieved.As a proof of concept,a spin-dependent Janus metasurface is designed and experimentally verified that four distinct images corresponding to four input states can be captured in the far-field.In addition,since the design method is derived from geometric optics,it can be easily applied to other spectra.We believe that the proposed metasurface doublet may empower many potential applications in chiral imaging,chiroptical spectroscopy and optical computing. | Yijia Huang Tianxiao Xiao Shuai Chen Zhengwei Xie Jie Zheng Jianqi Zhu Yarong Su Weidong Chen Ke Liu Mingjun Tang Peter Müller-Buschbaum Ling Li | 2023 | Opto-Electronic Advances2023,6,7: | 2 |
| 7 | Characteristics and Possible Formation Mechanisms of Severe Storms in the Outer Rainbands of Typhoon Mujigae(1522)显示文摘To better understand how severe storms form and evolve in the outer rainbands of typhoons, in this study, we investigate the evolutionary characteristics and possible formation mechanisms for severe storms in the rainbands of Typhoon Mujigae, which occurred during 2–5 October 2015, based on the NCEP–NCAR reanalysis data, conventional observations, and Doppler radar data. For the rainbands far from the inner core(eye and eyewall) of Mujigae(distance of approximately 70–800 km), wind speed first increased with the radius expanding from the inner core, and then decreased as the radius continued to expand. The Rankine Vortex Model was used to explore such variations in wind speed. The areas of strong stormy rainbands were mainly located in the northeast quadrant of Mujigae, and overlapped with the areas of high winds within approximately 300–550 km away from the inner core, where the strong winds were conducive to the development of strong storms. A severe convective cell in the rainbands developed into waterspout at approximately 500 km to the northeast of the inner core, when Mujigae was strengthening before it made landfall. Two severe convective cells in the rainbands developed into two tornadoes at approximately350 km to the northeast of the inner core after Mujigae made landfall. The radar echo bands enhanced to 60 d BZ when mesocyclones occurred in the rainbands and induced tornadoes. The radar echoes gradually weakened after the mesocyclones weakened. The tops of parent clouds of the mesocyclones elevated at first, and then suddenly dropped about 20 min before the tornadoes appeared. Thereby, the cloud top variation has the potential to be used as an early warning of tornado occurrence. | Bingyun WANG Ming WEI Wei HUA Yongli ZHANG Xiaohang WEN Jiafeng ZHENG Nan LI Han LI Yu WU Jie ZHU Mingjun ZHANG | 2017 | Journal of Meteorological Research2017,31,3: | 2 |

| 10 | Identification and analysis of AP2/ERF gene family in tomato underabiotic stress显示文摘AP2/ERE-type transcription factors,as a type of plant-specific transcription factors,play a key role in plant biotic and abiotic stress.Meanwhile,they have been studied in many plants,but rarely in tomatoes.In this study,we performed a genome-wide analysis of the SlAP2/ERF gene family of tomato,and finally identified 29 SlAP2/ERF genes and divided them into different subfamilies.At the same time,its basic physical and chemical properties were analyzed.We also constructed phylogenetic trees with 30 Arabidopsis AP2/ERF proteins and 28 potatoes AP2/ERF proteins to ensure conservative homology between them.In addition,we mapped 29 SlAP2/ERF transcription factors on 10 different chromosomes,and identified 43 responsive plant hormones,responsive light signals,tissue-specific expression and stress response elements from 2000bp upstream of the promoter region,and we analyzed conserved motifs and gene structures of SlAP2/ERF.The tertiary structure of SlAP2/ERF protein was constructed by homology modeling,and the protein-protein interaction network was constructed based on Arabidopsis Thaliana.Finally,the expression pattern of tomato in different tissues was studied by using gene expression database,and the expression level of tomato under abiotic stress was detected by q-RT-PCR.These results provide comprehensive information for further study of the function of the SlAP2/ERF gene family. | XIAOLIN ZHU XIAOHONG WEI BAOQIANG WANG XIAN WANG MINGJUN ZHANG | 2020 | BIOCELL2020,44,4: | 1 |

| 16 | Aldosterone may induce visfatin expression via the GR-ERK1/2 signal pathway in 3T3-L1 adipocytes显示文摘The main function of aldosterone is to regulate blood pressure and electrolytic balance;however,recent studies have also focused on the effect of aldosterone on glucose metabolism especially in adipose tissue.Aldosterone was found to inhibit insulin-induced glucose uptake in 3T3-L1 adipocytes [1] and aldosterone deficiency was found to prevent high-fat-feeding-induced hyperglycemia and adipocyte dysfunction in mice [2].Visfatin,an adipokine discovered by the team of Fukuhara,is mainly released by adipose tissue [3].Treatment of 3T3-L1 adipocytes and L6 myocytes with visfatin increased basal glucose uptake,and glucose release was suppressed in H4IIEC3 hepatocytes after visfatin treatment [3].It has also been suggested that visfatin may act as a proinflammatory cytokine [4] and produce chronic inflammation in adipocytes [5].Eyileten et al.[6] reported that treatment with angiotensin-converting enzyme inhibitor,which can reduce plasma aldosterone concentration,decreased circulating visfatin level in diabetic nephropathy patients.These findings suggest a possible interaction between the renin–angiotensin–aldosterone system(RAAS)and visfatin.Considering the important roles of aldosterone and visfatin and the association between RAAS and visfatin,we hypothesize that there may be a direct regulatory interaction between aldosterone and visfatin.To test this hypothesis,3T3-L1 adipocytes were used as the cell model and the expression of visfatin was measured by qRT-PCR and western blot analysis. | Junhua Ma Xuemei Zhao Jichen Zhang Fei Sun Jiancan Lu Hongling Zhu Mingjun Gu Jingnan Wang Xiangqi Li | 2019 | Acta Biochimica et Biophysica Sinica2019,51,3: | 1 |

| 20 | Trends and Uncertainties in Surface Air Temperature over the Tibetan Plateau,1951–2013显示文摘Trends and uncertainties of surface air temperature over the Tibetan Plateau(TP)are evaluated by using observations at 100 meteorological stations during the period 1951–2013.The sampling error variances of gridded monthly data are estimated for every month and every grid box of data.The gridded data and their sampling error variances are used to calculate TP averages,their trends,and associated uncertainties.It is shown that large sampling error variances dominate northern and western TP,while small variances appear over southern and eastern TP.Every month from January to December has a positive linear trend during the study period.February has the largest trend of 0.34±0.18°C(10 yr)^(–1),and April the smallest at 0.15±0.11°C(10 yr)^(–1).The uncertainties decrease steadily with time,implying that they are not large enough to alter the TP warming trend. | Wei HUA Guangzhou FAN Yiwei ZHANG Lihua ZHU Xiaohang WEN Yongli ZHANG Xin LAI Binyun WANG Mingjun ZHANG Yao HU Qiuyue WU | 2017 | Journal of Meteorological Research2017,31,2: | 1 |
