| 2 | Coking kinetics and influence of reaction-regeneration on acidity, activity and deactivation of Zn/HZSM-5 catalyst during methanol aromatization显示文摘The coking kinetics and reaction-regeneration on Zn/HZSM-5(Zn/HZ) catalyst in the conversion of methanol to aromatics were investigated.The highest initial benzene, toluene and xylene(BTX) yield of ca. 67.7% was obtained on fresh Zn/HZ catalyst, which showed the worst catalytic stability. The cycle of reaction-regeneration significantly modified the texture and acidity of Zn/HZ catalyst, which in turn affected its catalytic performance and coking behavior in methanol conversion to BTX. The residual carbon located on the surface of Zn/HZ catalyst led to the decrease of acid sites and the change on the acid sites distribution, which played an important roles on its activity and deactivation. It was found that the high B/L ratio and the low total acid sites concentration of the Zn/HZ catalyst favored to the high BTX yield and good catalytic stability in methanol conversion. | Guiquan Zhang Xin Zhang Ting Bai Tengfei Chen Wentao Fan | 2015 | Journal of Energy Chemistry2015,24,1: | 11 |
| 3 | Geologic investigation and mapping of the Sinus Iridum quadrangle from Clementine, SELENE, and Chang’e-1 data显示文摘The objectives of lunar satellite remote sensing are to study lunar surface characteristics, inner structure, and its evolution history. The contents of TiO 2 and FeO are assessed from Clementine UV/VIS data for Sinus Iridum. The geologic stratigraphic units and crates are interpreted visually based on SELENE Terrain Camera (TC) images and the spatial resolution of which is up to 10 m. And the geologic ages of different stratigraphic units are calculated by the crater size-frequency distributions measurements. The gravity anomaly is generated from SELENE gravity model (SGM90d) to show its difference from Mare Imbrium. Furthermore, the thickness of lunar regolith is also derived from microwave radiometer data of Chang’e-1 satellite. Integrating these results, it shows that the Sinus Iridum is different from the Mare Imbrium in inner structure and surface sedimentation. And its history of subsidence, deposition, volcanism, and impact is described. It makes sense to the future soft-landing and sampling at potential Sinus Iridum by remote sensing geologic analysis. | CHEN ShengBo , MENG ZhiGuo, CUI TengFei, LIAN Yi, WANG JingRan & ZHANG XuQing College of Geoexploration Science and Technology, Jilin University, Changchun 130026, China | 2010 | Science China(Physics,Mechanics & Astronomy)2010,53,12: | 10 |

| 6 | Durability of neutralizing antibodies and T-cell response post SARS-CoV-2 infection显示文摘The ongoing pandemic of coronavirus disease 19(COVID-19)is caused by a newly discoveredβcoronavirus named severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).How long the adaptive immunity triggered by SARS-CoV-2 can last is of critical clinical relevance in assessing the probability of second infection and efficacy of vaccination.Here we examined,using ELISA,the IgG antibodies in serum specimens collected from 17 COVID-19 patients at 6–7 months after diagnosis and the results were compared to those from cases investigated 2 weeks to 2 months post-infection.All samples were positive for IgGs against the S-and N-proteins of SARS-CoV-2.Notably,14 samples available at 6–7 months post-infection all showed significant neutralizing activities in a pseudovirus assay,with no difference in blocking the cell-entry of the 614D and 614G variants of SARS-CoV-2.Furthermore,in 10 blood samples from cases at 6–7 months post-infection used for memory T-cell tests,we found that interferonγ-producing CD4+and CD8+cells were increased upon SARS-CoV-2 antigen stimulation.Together,these results indicate that durable anti-SARS-CoV-2 immunity is common in convalescent population,and vaccines developed from 614D variant may offer protection from the currently predominant 614D variant of SARS-CoV-2. | Yun Tan Feng Liu Xiaoguang Xu Yun Ling Weijin Huang Zhaoqin Zhu Mingquan Guo Yixiao Lin Ziyu Fu Dongguo Liang Tengfei Zhang Jian Fan Miao Xu Hongzhou Lu Saijuan Chen | 2020 | Frontiers of Medicine2020,14,6: | 6 |
| 7 | Functionalized graphene oxide based on p-phenylenediamine as spacers and nitrogen dopants for high performance supercapacitors显示文摘p-Phenylenediamine(PPD)functionalized graphene oxide(GO)materials(PPDG)were prepared through a one-step solvothermal process and their application as supercapacitors(SCs)were studied.The PPD is not only as the spacers to prevent aggregating and restacking of the graphene sheets in the preparing process but also as nitrogen sources to obtain the nitrogen-doped graphene.The structures of PPDG were characterized by Fourier transformed infrared spectroscopy(FT-IR),X-ray diffraction spectroscopy(XRD),Raman spectroscopy and X-ray photoelectron spectroscopy(XPS)and the results show that the nitrogen-doped graphene was achieved with nitrogen content as high as 10.85 at.%.The field emission scanning electron microscopy(FE-SEM)and high resolution transmission electron microscopy(HR-TEM)have confirmed that the morphologies of PPDG were loose layered with less aggregation,indicating that PPD molecules,as spacers,effectively prevent the graphene sheets from restacking during the solvothermal reaction.The special loose textures make PPDG materials exhibit excellent electrochemical performance for symmetric SCs with superior specific capacitance(313 F/g at 0.1 A/g),rate capability and cycling stability.The present synthesis method is convenient and may have potential applications as ultrahigh performance SCs. | Yanhong Lu Yi Huang Fan Zhang Long Zhang Xi Yang Tengfei Zhang Kai Leng Mingjie Zhang Yongsheng Chen | 2014 | Chinese Science Bulletin2014,59,16: | 5 |
| 8 | Protective effect of oxysophoridine on cerebral ischemia/reperfusion injury in mice显示文摘Oxysophoridine, a new alkaloid extracted from Sophora alopecuroides L., has been shown to have a protective effect against ischemic brain damage. In this study, a focal cerebral ischemia/reperfusion injury model was established using middle cerebral artery occlusion in mice. Both 62.5, 125, and 250 mg/kg oxysophoridine, via intraperitoneal injection, and 6 mg/kg nimodipine, via intragastric administration, were administered daily for 7 days before modeling. After 24 hours of reperfusion, mice were tested for neurological deficit, cerebral infarct size was assessed and brain tissue was collected. Results showed that oxysophoridine at 125, 250 mg/kg and 6 mg/kg nimodipine could reduce neurological deficit scores, cerebral infarct size and brain water content in mice. These results provided evidence that oxysophoridine plays a protective role in cerebral ischemia/reperfusion injury. In addition, oxysophoridine at 62.5, 125, and 250 mg/kg and 6 mg/kg nimodipine increased adenosine-triphosphate content, and decreased malondialdehyde and nitric oxide content. These compounds enhanced the activities of glutathione-peroxidase, superoxide dismutase, catalase, and lactate dehydrogenase, and decreased the activity of nitric oxide synthase. Protein and mRNA expression levels of N-methyl-D-aspartate receptor subunit NR1 were markedly inhibited in the presence of 250 mg/kg oxysophoridine and 6 mg/kg nimodipine. Our experimental findings indicated that oxysophoridine has a neuroprotective effect against cerebral ischemia/reperfusion injury in mice, and that the effect may be due to its ability to inhibit oxidative stress and expression of the N-methyl-D-aspartate receptor subunit NR1. | Hongbo Wang Yuxiang Li Ning Jiang Xiaoping Chen Yi Zhang Kuai Zhang Tengfei Wang Yinju Hao Lin Ma Chengjun Zhao Yanrong Wang Tao Sun Jianqiang Yu | 2013 | Neural Regeneration Research2013,8,15: | 5 |
| 9 | Detecting maize leaf water status by using digital RGB images显示文摘To explore the correlation between crop leaf digital RGB(Red,Green and Blue)image features and the corresponding moisture content of the leaf,a Canon digital camera was used to collect image information from detached leaves of heading-stage maize.A drying method was adopted to measure the moisture content of the leaf samples,and image processing technologies,including gray level co-occurrence matrices and grayscale histograms,was used to extract the maize leaf texture feature parameters and color feature parameters.The correlations of these feature parameters with moisture content were analyzed.It is found that the texture parameters of maize leaf RGB images,including contrast,correlation,entropy and energy,were not significantly correlated with moisture content.Thus,it was difficult to use these features to predict moisture content.Of the six groups of eigenvalues for the leaf color feature parameters,including mean,variance,energy,entropy,kurtosis and skewness,mean and kurtosis were found to be correlated with moisture content.Thus,these features could be used to predict the leaf moisture content.The correlation coefficient(R2)of the mean-moisture content relationship model was 0.7017,and the error of the moisture content prediction was within±2%.The R2 of the kurtosis-moisture content relationship model was 0.7175,and the error of the moisture content prediction was within±1.5%.The study results proved that RGB images of crop leaves could be used to measure moisture content. | Han Wenting Sun Yu Xu Tengfei Chen Xiangwei Su Ki Ooi | 2014 | International Journal of Agricultural and Biological Engineering2014,7,1: | 5 |
| 10 | NEDD9 promotes cancer stemness by recruiting myeloid-derived suppressor cells via CXCL8 in esophageal squamous cell carcinoma显示文摘Objective:Esophageal squamous cell carcinoma(ESCC)has high morbidity and mortality rates worldwide.Cancer stem cells(CSCs)may cause tumor initiation,metastasis,and recurrence and are also responsible for chemotherapy and radiotherapy failures.Myeloid-derived suppressor cells(MDSCs),in contrast,are known to be involved in mediating immunosuppression.Here,we aimed to investigate the mechanisms of interaction of CSCs and MDSCs in the tumor microenvironment.Methods:ESCC tissues and cell lines were evaluated.Neural precursor cell expressed,developmentally downregulated 9(NEDD9)was knocked down and overexpressed by lentiviral transfection.Quantitative PCR,Western blot,immunohistochemistry,cell invasion,flow cytometry,cell sorting,multiplex chemokine profiling,and tumor growth analyses were performed.Results:Microarray analysis revealed 10 upregulated genes in esophageal CSCs.Only NEDD9 was upregulated in CSCs using the sphere-forming method.NEDD9 expression was correlated with tumor invasion(P=0.0218),differentiation(P=0.0153),and poor prognosis(P=0.0373).Additionally,NEDD9 was required to maintain the stem-like phenotype.Screening of chemokine expression in ESCC cells with NEDD9 overexpression and knockdown showed that NEDD9 regulated C-X-C motif chemokine ligand 8(CXCL8)expression via the ERK pathway.CXCL8 mediated the recruitment of MDSCs induced by NEDD9 in vitro and in vivo.MDSCs promoted the stemness of ESCC cells through NEDD9 via the Notch pathway.Conclusions:As a marker of ESCC,NEDD9 maintained the stemness of ESCC cells and regulated CXCL8 through the ERK pathway to recruit MDSCs into the tumor,suggesting NEDD9 as a therapeutic target and novel prognostic marker for ESCC. | Dongli Yue Shasha Liu Tengfei Zhang Yong Wang Guohui Qin Xinfeng Chen Huanyu Zhang Dong Wang Lan Huang Feng Wang Liping Wang Song Zhao Yi Zhang | 2021 | Cancer Biology & Medicine2021,18,3: | 4 |

| 12 | Research on water ice content in Cabeus crater using the data from the microwave radiometer onboard Chang’e-1 satellite显示文摘The existence, formation and content of water ice in the lunar permanently shaded region is one of the important questions for the current Moon study. On October 9, 2009, the LCROSS mission spacecraft impacted the Moon, and the initial result verified the existence of water on the Moon. But the study on formation and content of water ice is still under debate. The existence of water ice can change the dielectric constants of the lunar regolith, and a microwave radiometer is most sensitive to the dielectric parameters. Based on this, in this paper, the radiation transfer model is improved according to the simulation results in high frequency. Then the mixture dielectric constant models, including Odelevsky model, Wagner and landau-Lifshitz model, Clau-sius model, Gruggeman-Hanai model, etc., are analyzed and compared. The analyzing results indicate that the biggest difference occurs between Lichtenecker model and the improved Dobson model. The values estimated by refractive model are the second biggest in all the models. And the results from Odelevsky model, strong fluctuation model, Wagner and Landau –Lifshitz model, Clausius model and Bruggeman-Hanai model are very near to each other. Thereafter, the relation between volume water ice content and microwave brightness temperature is constructed with Odelevsky mixing dielectric model and the improved radiative transfer simulation, and the volume water ice content in Cabeus crater is retrieved with the data from microwave radiometer onboard Chang’e-1 satellite. The results present that the improved radiative transfer model is proper for the brightness temperature simulation of the one infinite regolith layer in high frequency. The brightness temperature in Cabeus crater is 69.93 K (37 GHz), and the corresponding volume water ice content is about 2.8%. | MENG ZhiGuo 1 , CHEN ShengBo 1* , Edward Matthew OSEI Jnr 2 , WANG ZiJun 1 & CUI TengFei 1 1 College of Geoexploration Science and Technology, Jilin University, Changchun 130026, China 2 Department of Geomatic Engineering, Kwame Nkrumah University of Science and Technology, Kumasi, Ghana | 2010 | Science China(Physics,Mechanics & Astronomy)2010,53,12: | 4 |

| 14 | Depression compromises antiviral innate immunity via the AVP-AHI1-Tyk2 axis显示文摘Depression is a serious public-health issue.Recent reports have suggested higher susceptibility to viral infections in depressive patients.However,how depression affects antiviral innate immune signaling remains unknown.Here,we revealed a reduction in expression of Abelson helper integration site 1(AHI1)in the peripheral blood mononuclear cells(PBMCs)and macrophages from the patients with major depressive disorder(MDD),which leads to attenuated antiviral immune response.We found that depression-related arginine vasopressin(AVP)induces reduction of AHI1 in macrophages.Further studies demonstrated that AHI1 is a critical stabilizer of basal type-I-interferon(IFN-I)signaling.Mechanistically,AHI1 recruits OTUD1 to deubiquitinate and stabilize Tyk2,while AHI1 reduction downregulates Tyk2 and IFN-I signaling activity in macrophages from both MDD patients and depression model mice.Interestingly,we identified a clinical analgesic meptazinol that effectively stimulates AHI1 expression,thus enhancing IFN-I antiviral defense in depression model mice.Our study promotes the understanding of the signaling mechanisms of depression-mediated antiviral immune dysfunction,and reveals meptazinol as an enhancer of antiviral innate immunity in depressive patients. | Hong-Guang Zhang Bin Wang Yong Yang Xuan Liu Junjie Wang Ning Xin Shifeng Li Ying Miao Qiuyu Wu Tingting Guo Yukang Yuan Yibo Zuo Xiangjie Chen Tengfei Ren Chunsheng Dong Jun Wang Hang Ruan Miao Sun Xingshun Xu Hui Zheng | 2022 | Cell Research2022,32,10: | 3 |
| 15 | Late Mesozoic rifting and its deep dynamic mechanisms in the central Sulu orogenic belt: Records from Lingshan Island显示文摘The Lingshan Island scientific drill confirms that two episodes(Laiyang period and Qingshan period) of rifting developed in the central Sulu orogenic belt(SOB) in Late Mesozoic. With a set of methods including fieldwork, drilling, core logging, zircon U-Pb dating and whole rock geochemistry applied, the age, the depositional sequence and the deep dynamic mechanisms of rift evolution were unraveled. The stratigraphic sequence of the Laiyang-Qingshan Groups on Lingshan Island was composed of two different rifting sequences:(1) Laiyang Group(147–125 Ma), which consists of deep-water gravity flow deposits with interlayers of intermediate volcanic rocks;and(2) Lower Qingshan Group(125–119 Ma), which unconformably overlies the former sequence and contains subaerial volcanic deposits and terrestrial deposits. The tectonic environment changed during the evolution of these two episodes of rifting: the rift was in a NNW-SSE extensional environment in the Laiyang period and showed the typical passive rifting character that “lithospheric extension and rifting preceded volcanism”. The passive rifting period was ended by a short WNW-ESE compression at about 125 Ma. After that, the tectonic environment transferred to a strong NW-SE extensional environment and the rifting evolved into a volcanic arc basin in the Qingshan period. The igneous rocks are shoshonitic to high-K calc-alkaline trachyandesites to trachytes with a few intercalated lamprophyres and a rhyolite.The geochemical characteristics of the igneous rocks indicate that they are mantle-derived melts with a metasomatized mantle source and/or crustal contamination. In addition, an increased thinning of the lithosphere happened during the rifting episodes.The low-angle subduction of the Paleo-Pacific plate in the Jurassic weakened the thickened SOB lithospheric mantle. The rollback of the subducting plate started in late Jurassic to early Cretaceous, and the SOB lithospheric mantle was delaminated synchronously because of the gravity collapse. Thus, this caused passive rifting in the Laiyang period. Thereafter, the rollback and trench retreat of the high-angle subducting Paleo-Pacific plate would have achieved its climax, resulting in the strong regional extension. Passive rifting was ended by the crustal uplift caused by asthenospheric upwelling beneath the rift. The lower crust was heated by the upwelling asthenosphere and partially melted to form felsic melts, which were emplaced upwards and erupted explosively. The rift evolved into a volcanic arc basin in the Qingshan period and showed some characteristics of active rifting. Above all, a passive rifting in the Laiyang period and a volcanic arc basin in the Qingshan period developed successively in the Lingshan Island area(the central SOB). This records the transfer of the study area from the Paleo-Tethys tectonic domain to the circum-Pacific tectonic domain. The delamination of SOB lithospheric mantle and the upwelling of asthenospheric material were the deep dynamic mechanisms driving the development and evolution of two rift episodes. Additionally, the rift development was controlled remotely by the subduction of the Paleo-Pacific plate. | Tengfei ZHOU Yaoqi ZHOU Nina SФAGER Paul Martin HOLM Zhenkai ZHANG Jun WANG Zhao LIANG Hongyu MU Yanjun CHENG Feifei LIU Miao WANG Yue ZHANG Hui ZHANG Yangjian GU Shihui DONG Hanjie ZHAO Manjie LI Yang CHEN Yanzi LIU | 2022 | Science China Earth Sciences2022,65,9: | 3 |
| 16 | Surface photovoltage phase spectroscopy study of the photo-induced charge carrier properties of TiO_(2) nanotube arrays显示文摘By using the surface photovoltage (SPV) technique based on a lock-in amplifier, surface states located 3.1 eV below the conduction band of TiO_(2) have been detected in TiO_(2) nanotube arrays prepared by anodization of titanium foil in fluoride-based ethylene glycol solution. The photo-induced charge transportation behavior of TiO_(2) nanotube arrays was also studied by quali- tatively analyzing their SPV phase spectra measured under different external bias. When a negative bias was applied, carriers excited from surface states have the same transportation properties as those excited from the valence band; in contrast, when a positive bias was applied, these two kinds of photo-excited carriers exhibit different transportation behavior.. | CHEN LiPing XIE TengFeng WANG DeJun FAN ZhiYong JIANG TengFei | 2012 | Science China Chemistry2012,55,2: | 3 |
| 17 | Enhancing oxygen evolution reaction by cationic surfactants显示文摘Oxygen evolution reaction is critical for water splitting or metal-air batteries,but previous research mainly focuses on electrode material or structure optimization.Herein,we demonstrate that surfactant modification of a NiFe layered double hydroxide (LDH) array electrode,one of the best catalysts for oxygen evolution reaction (OER),could achieve superaerophobic surface with balanced surface charges,affording fast mass transfer,quick gas release,and boosted OER performance.The assembled surfactants on the electrode surface are responsible for lowering the bubble adhesive force (~ 1.03 μN) and corresponding fast release of small bubbles generated during OER.In addition,the bipolar nature of the hexadecyl trimethyl ammonium bromide (CTAB) molecule lead to bilayer assembly of the surfactants with the polar ends facing the electrode surface and the electrolyte,resulting in neutralized charges on the electrode surface.As a result,OH-transfer was facilitated and OER performance was enhanced.With the modified superaerophobic surface and balanced surface charge,NiFe LDHs-CTAB nanostructured electrode showed ultrahigh current density increase (9.39 mA(mV·cm^2)),2.3 times higher than that for conventional NiFe LDH nanoarray electrode),dramatically fast gas release,and excellent durability.The introduction of surfactants to construct under-water superaerophobic electrode with in-time repelling ability to the as-formed gas bubbles may open up a new pathway for designing efficient electrodes for gas evolution systems with potentially practical application in the near future. | Qixian Xie Daojin Zhou Pengsong Li Zhao Cai Tianhui Xie Tengfei Gao Ruida Chen Yun Kuang Xiaoming Sun | 2019 | Nano Research2019,12,9: | 3 |
| 18 | Fabrication and performance evaluation of novel transparent ceramics RE:Tb_(3)Ga_(5)O_(12)(RE=Pr,Tm,Dy)toward magneto-optical application显示文摘Transparent ceramics are at the heart of modern magneto-optical materials providing promising opportunities for Faraday isolators.1.0 at%RE:Tb3Ga5O12(rare earth(RE)=Pr,Tm,Dy)transparent ceramics were successfully prepared by air sintering and sequential HIP technique using the coprecipitated powders as the raw material.All the powders have shown to be a pure cubic terbium gallium garnet(TGG)phase and exhibit good dispersion.Additionally,a change could not be observed in particle shape with the different doped ions.After the two-step sintering,all the obtained ceramics have good optical quality,and the in-line transmittances at 1070 nm are higher than 80%.Moreover,no secondary phase can be detected from the microstructures.However,the pores which remain entrapped in the ceramics can be noted.The Verdet constant of ceramic samples is optimized by RE doping,and the Verdet constant at 632.8 nm is about−143 rad·T^(−1)·m^(−1),which is about 5%higher than that of TGG ceramics.Finally,the thermo-optical properties of 1.0 at%RE:TGG transparent ceramics are compared.The annealed TGG ceramic showed the best thermo-optical properties,and the thermally induced depolarization of 1.0 at%Ce:TGG and 1.0 at%Tm:TGG was inferior to that of annealed TGG ceramic. | Xiaoying Li Ilya LSnetkov Aleksey Yakovlev Qiang Liu Xin Liu Ziyu Liu Penghui Chen Danyang Zhu Lexiang Wu Zhaoxiang Yang Tengfei Xie Haohong Chen Oleg Palashov Jiang Li | 2021 | Journal of Advanced Ceramics2021,10,2: | 3 |
| 19 | Development of a fine-resolution atmosphere-wave-ocean coupled forecasting model for the South China Sea and its adjacent seas显示文摘A 72-h fine-resolution atmosphere-wave-ocean coupled forecasting system was developed for the South China Sea and its adjacent seas. The forecasting model domain covers from from 15°S to 45°N in latitude and 99°E to135°E in longitude including the Bohai Sea, the Yellow Sea, the East China Sea, the South China Sea and the Indonesian seas. To get precise initial conditions for the coupled forecasting model, the forecasting system conducts a 24-h hindcast simulation with data assimilation before forecasting. The Ensemble Adjustment Kalman Filter(EAKF) data assimilation method was adopted for the wave model MASNUM with assimilating Jason-2 significant wave height(SWH) data. The EAKF data assimilation method was also introduced to the ROMS model with assimilating sea surface temperature(SST), mean absolute dynamic topography(MADT) and Argo profiles data. To improve simulation of the structure of temperature and salinity, the vertical mixing scheme of the ocean model was improved by considering the surface wave induced vertical mixing and internal wave induced vertical mixing. The wave and current models were integrated from January 2014 to October 2015 driven by the ECMWF reanalysis 6 hourly mean dataset with data assimilation. Then the coupled atmosphere-wave-ocean forecasting system was carried out 14 months operational running since November 2015. The forecasting outputs include atmospheric forecast products, wave forecast products and ocean forecast products. A series of observation data are used to evaluate the coupled forecasting results, including the wind, SHW, ocean temperature and velocity.The forecasting results are in good agreement with observation data. The prediction practice for more than one year indicates that the coupled forecasting system performs stably and predict relatively accurate, which can support the shipping safety, the fisheries and the oil exploitation. | Junchuan Sun Zexun Wei Tengfei Xu Meng Sun Kun Liu Yongzeng Yang Li Chen Hong Zhao Xunqiang Yin Weizhong Feng Zhiyuan Zhang Yonggang Wang | 2019 | Acta Oceanologica Sinica2019,38,4: | 3 |
| 20 | Natural variations of ZmSRO1d modulate the trade-off between drought resistance and yield by affecting ZmRBOHC-mediated stomatal ROS production in maize显示文摘While crop yields have historically increased,drought resistance has become a major concern in the context of global climate change.The trade-off between crop yield and drought resistance is a common phenomenon;however,the underlying molecular modulators remain undetermined.Through genome-wide association study,we revealed that three non-synonymous variants in a drought-resistant allele of ZmSRO1d-R resulted in plasma membrane localization and enhanced mono-ADP-ribosyltransferase activity of ZmSRO1d toward ZmRBOHC,which increased reactive oxygen species(ROS)levels in guard cells and promoted stomatal closure.ZmSRO1d-R enhanced plant drought resilience and protected grain yields under drought conditions,but it led to yield drag under favorable conditions.In contrast,loss-of-function mutants of ZmRBOHC showed remarkably increased yields under well-watered conditions,whereas they showed compromised drought resistance.Interestingly,by analyzing 189 teosinte accessions,we found that the ZmSRO1d-R allele was present in teosinte but was selected against during maize domestication and modern breeding.Collectively,our work suggests that the allele frequency reduction of ZmSRO1d-R in breeding programs may have compromised maize drought resistance while increased yields.Therefore,introduction of the ZmSRO1d-R allele into modern maize cultivars would contribute to food security under drought stress caused by global climate change. | Huajian Gao Junjun Cui Shengxue Liu Shuhui Wang Yongyan Lian Yunting Bai Tengfei Zhu Haohao Wu Yijie Wang Shiping Yang Xuefeng Li Junhong Zhuang Limei Chen Zhizhong Gong Feng Qin | 2022 | Molecular Plant2022,15,10: | 2 |
