| 2 | Enhanced secondary pollution offset reduction of primary emissions during COVID-19 lockdown in China显示文摘To control the spread of the 2019 novel coronavirus(COVID-19),China imposed nationwide restrictions on the movement of its population(lockdown)after the Chinese New Year of 2020,leading to large reductions in economic activities and associated emissions.Despite such large decreases in primary pollution,there were nonetheless several periods of heavy haze pollution in eastern China,raising questions about the well-established relationship between human activities and air quality.Here,using comprehensive measurements and modeling,we show that the haze during the COVID lockdown was driven by enhancements of secondary pollution.In particular,large decreases in NOx emissions from transportation increased ozone and nighttime NO_(3)radical formation,and these increases in atmospheric oxidizing capacity in turn facilitated the formation of secondary particulate matter.Our results,afforded by the tragic natural experiment of the COVID-19 pandemic,indicate that haze mitigation depends upon a coordinated and balanced strategy for controlling multiple pollutants. | Xin Huang Aijun Ding Jian Gao Bo Zheng Derong Zhou Ximeng Qi Rong Tang Jiaping Wang Chuanhua Ren Wei Nie Xuguang Chi Zheng Xu Liangduo Chen Yuanyuan Li Fei Che Nini Pang Haikun Wang Dan Tong Wei Qin Wei Cheng Weijing Liu Qingyan Fu Baoxian Liu Fahe Chai Steven JDavis Qiang Zhang Kebin He | 2021 | National Science Review2021，8，2： | 47 |

| 4 | Rainfall and inflow effects on soil erosion for hillslopes dominated by sheet erosion or rill erosion in the Chinese Mollisol region显示文摘Erosion agents and patterns profoundly affect hillslope soil loss characteristics. However, few attempts have been made to analyze the effects of rainfall and inflow on soil erosion for hillslopes dominated by sheet erosion or rill erosion in the Chinese Mollisol region. The objective of this study was to discuss the erosive agent(rainfall or inflow), hillslope erosion pattern(sheet erosion or rill erosion) and slope gradient effects on runoff and soil losses. Two soil pans(2.0 m long, 0.5 m wide and 0.5 m deep) with 5° and 10° slopes were subjected to rainfall(0 and 70 mm h–1) and inflow(0 and 70 mm h–1) experiments. Three experimental combinations of rainfall intensity(RI) and inflow rate(IR) were tested using the same water supply of 70 mm by controllingthe run time. A flat soil surface and a soil bed with a straight initial rill were prepared manually, and represented hillslopes dominated by sheet erosion and rill erosion, respectively. The results showed that soil losses had greater differences among treatments than total runoff. Soil losses decreased in the order of RI70+IR70 > RI70+IR0 > RI0+IR70. Additionally, soil losses for hillslopes dominated by rill erosion were 1.7-2.2 times greater at 5° and 2.5-6.9 times greater at 10° than those for hillslopes dominated by sheet erosion. The loss of <0.25 mm soil particles and aggregates varying from 47.72%-99.60% of the total soil loss played a dominant role in the sediment. Compared with sheet erosion hillslopes, rill erosion hillslopes selectively transported more microaggregates under a relatively stable rill development stage, but rills transported increasinglymore macroaggregates under an active rill development stage. In conclusion, eliminating raindrop impact on relatively gentle hillslopes and preventing rill development on relatively steep hillslopes would be useful measures to decrease soil erosion and soil degradation in the Mollisol region of northeastern China. | SHEN Hai-ou WEN Lei-lei HE Yun-feng HU Wei LI Hong-li CHE Xiao-cui LI Xin | 2018 | Journal of Mountain Science2018，15，10： | 12 |
| 5 | Mapping the permafrost stability on the Tibetan Plateau for 2005–2015显示文摘Data scarcity is a major obstacle for high-resolution mapping of permafrost on the Tibetan Plateau(TP).This study produces a new permafrost stability distribution map for the 2010 s(2005–2015)derived from the predicted mean annual ground temperature(MAGT)at a depth of zero annual amplitude(10–25 m)by integrating remotely sensed freezing degree-days and thawing degree-days,snow cover days,leaf area index,soil bulk density,high-accuracy soil moisture data,and in situ MAGT measurements from 237 boreholes on the TP by using an ensemble learning method that employs a support vector regression model based on distance-blocked resampled training data with 200 repetitions.Validation of the new permafrost map indicates that it is probably the most accurate of all currently available maps.This map shows that the total area of permafrost on the TP,excluding glaciers and lakes,is approximately 115.02(105.47–129.59)×10^4 km^2.The areas corresponding to the very stable,stable,semi-stable,transitional,and unstable types are 0.86×10^4,9.62×10^4,38.45×10^4,42.29×10^4,and 23.80×10^4 km^2,respectively.This new map is of fundamental importance for engineering planning and design,ecosystem management,and evaluation of the permafrost change in the future on the TP as a baseline. | Youhua RAN Xin LI Guodong CHENG Zhuotong NAN Jinxing CHE Yu SHENG Qingbai WU Huijun JIN Dongliang LUO Zhiguang TANG Xiaobo WU | 2021 | Science China Earth Sciences2021，64，1： | 11 |
| 6 | Effect of Mo on High-Temperature Fatigue Behavior of 15CrNbTi Ferritic Stainless Steel显示文摘In order to understand the effect of Mo element on the high-temperature fatigue behavior of 15 CrNbTi ferritic stainless steel, the stress-controlled fatigue tests have been performed for both 15 CrNbTi and 15Cr0.5MoNbTi ferritic stainless steels at 800 °C in laboratory air. The fatigue test results indicate that the fatigue resistance of 15Cr0.5MoNbTi steel is manifestly higher than that of 15 CrNbTi steel at the maximum stress below 57 MPa; the 15Cr0.5MoNbTi steel possesses a fatigue limit of 35 MPa, which is higher than that of 15 CrNbTi steel. The TEM observations reveal that the Mo element can suppress the formation of coarsened Fe3Nb3 C precipitates and result in the fatigue resistance enhancement.The dislocation networks formed during the cyclic load favor to improve the fatigue resistance of 15Cr0.5MoNbTi steel at800 °C. | Tianlong Liu Lijia Chen Hongyun Bi Xin Che | 2014 | Acta Metallurgica Sinica(English Letters)2014，27，3： | 10 |
| 7 | MdATG18a overexpression improves basal thermotolerance in transgenic apple by decreasing damage to chloroplasts显示文摘High temperature is an abiotic stress factor that threatens plant growth and development.Autophagy in response to heat stress involves the selective removal of heat-induced protein complexes.Previously,we showed that a crucial autophagy protein from apple,MdATG18a,has a positive effect on drought tolerance.In the present study,we treated transgenic apple(Malus domestica)plants overexpressing MdATG18a with high temperature and found that autophagy protected them from heat stress.Overexpression of MdATG18a in apple enhanced antioxidase activity and contributed to the production of increased beneficial antioxidants under heat stress.Transgenic apple plants exhibited higher photosynthetic capacity,as shown by the rate of CO_(2) assimilation,the maximum photochemical efficiency of photosystem II(PSII),the effective quantum yield,and the electron transport rates in photosystems I and II(PSI and PSII,respectively).We also detected elevated autophagic activity and reduced damage to chloroplasts in transgenic plants compared to WT plants.In addition,the transcriptional activities of several HSP genes were increased in transgenic apple plants.In summary,we propose that autophagy plays a critical role in basal thermotolerance in apple,primarily through a combination of enhanced antioxidant activity and reduced chloroplast damage. | Liuqing Huo Xun Sun Zijian Guo Xin Jia Runmin Che Yiming Sun Yanfei Zhu Ping Wang Xiaoqing Gong Fengwang Ma | 2020 | Horticulture Research2020，7，1： | 9 |
| 8 | Overexpression of MdATG18a in apple improves resistance to Diplocarpon mali infection by enhancing antioxidant activity and salicylic acid levels显示文摘Marssonina apple blotch,caused by Diplocarpon mali,is one of the most serious diseases of apple.Autophagy plays a key role in pathogen resistance.We previously showed that MdATG18a has a positive influence on drought tolerance.Herein,we describe how overexpression(OE)of MdATG18a enhances resistance to D.mali infection,probably because less H2O2 but more salicylic acid(SA)is accumulated in the leaves of OE apple plants.Expression of chitinase,β-1,3-glucanase,and SA-related marker genes was induced more strongly by D.mali in OE lines.Transcript levels of other important MdATG genes were also drastically increased by D.mali in OE plants,which indicated increased autophagy activities.Taken together,these results demonstrate that OE of MdATG18a enhances resistance to infection by D.mali and plays positive roles in H2O2-scavenging and SA accumulations.Our findings provide important information for designing strategies which could induce autophagy to minimize the impact of this disease on apple production. | Xun Sun Liuqing Huo Xin Jia Runmin Che Xiaoqing Gong Ping Wang Fengwang Ma | 2018 | Horticulture Research2018，5，1： | 8 |
| 9 | Protective effect of Yiguanjian decoction against DNA damage on concanavalin A-induced liver injury mice model显示文摘OBJECTIVE:To investigate the inhibitory effect of Yiguanjian decoction(YD) on DNA damage in Concanavalin A(Con A)-induced liver injury mice model and to explain the possible mechanism.METHODS:Totally 120 male BALB/c mice were randomly divided into 6 groups,20 mice each:normal group,model group,Bifendate group,YD low dose group,YD middle dose group and YD high dose group.Except normal group,liver injury model induced by Con A was established.While modeling,each mouse in YD group was given YD(0.4 m L/20 g per day) by intragastric administration(0.13 g YD for YD low dose group;0.26 g for YD middle dose group;0.52 g for YD high dose group).Bifendate group was given Bifendate(0.2 gnd model·kg-1 grou·d-1) by gavage.Normal group ap were fed with same volume of physiological saline daily.After 8 weeks,the serum alanine transaminase(ALT)and aspartate transaminase(AST) were tested.The hematoxylin-eosin staining was used to evaluate the grade of liver inflammation and liver fibrosis stage.Hepatocellular DNA damage was detected by single cell gel electrophoresis technology.The protein expression of tumor necrosis factor-α(TNF-α),Bax and Mut T Homolog 1(MTH1) was detected by western blotting and enzyme linked immunosorbent assay.Bax m RNA and MTH1 m RNA were detected by Real-time Polymerase Chain Reaction(PCR).RESULTS:YD can improve the degree of liver inflammation and fibrosis in the liver of chronic hepatitis mice,the dose effect relationship is remarkable(P < 0.05).YD can reduce liver cell DNA damage.The difference between YD middle dose group and model group was statistically significant(P < 0.05).YD middle dose group had decreased the protein expression of TNF-α in the mice liver of immunological liver injury(P < 0.05).YD can increase the protein expression of Bax(P < 0.05).Compared with normal group,the protein expression of MTH1 was decreased(P < 0.05),but there was no statistical significance between YD group and model group(P >0.05).YD can increase the m RNA expression of Bax and MTH1(both P < 0.05).CONCLUSION:YD can effectively inhibit the DNA damage in immunological liver injury mice,the mechanism may be that it can decrease the TNF-αand increase the Bax and MTH1 expression. | Tian Mengxi Liu Wenlan You Hongjie Zhao Qingzhou Ouyang Luodan Gao Biane Zhang Xin Che Niancong | 2016 | Journal of Traditional Chinese Medicine2016，36，4： | 7 |
| 10 | Monitoring the frozen duration of Qinghai Lake using satellite passive microwave remote sensing low frequency data显示文摘The Qinghai Lake is the largest inland lake in China.The significant difference of dielectric properties between water and ice suggests that a simple method of monitoring the Qinghai lake freeze-up and break-up dates using satellite passive microwave remote sensing data could be used.The freeze-up and break-up dates from the Qinghai Lake hydrological station and the MODIS L1B reflectance data were used to validate the passive microwave remote sensing results.The validation shows that passive microwave remote sensing data can accurately monitor the lake ice.Some uncertainty comes mainly from the revisit frequency of satellite overpass.The data from 1978 to 2006 show that lake ice duration is reduced by about 14―15 days.The freeze-up dates are about 4 days later and break-up dates about 10 days earlier.The regression analyses show that,at the 0.05 significance level,the correlations are 0.83,0.66 and 0.89 between monthly mean air temperature(MMAT) and lake ice duration days,freeze-up dates,break-up dates,respectively.Therefore,inter-annual variations of the Qinghai Lake ice duration days can significantly reflect the regional climate variation. | CHE Tao LI Xin JIN Rui | 2009 | Chinese Science Bulletin2009，54，13： | 5 |
| 11 | The evolution of microstructure and texture of AZ80 Mg alloy cup-shaped pieces processed by rotating backward extrusion显示文摘This study proposed an effective plastic deformation technique,rotating backward extrusion(RBE),for producing high performance AZ80 magnesium alloy cup-shaped pieces.The RBE process was carried on the Gleeble-3500 test machine at 653 K,and the conventional backward extrusion(CBE)was also conducted for comparison.A detailed microstructure analysis was performed using the optical microscopy(OM)and electron back-scatter diffraction(EBSD).The results shown that the equivalent strain and deformation uniformity of the cup pieces could be substantially increased by the RBE process compared with the CBE process.Furthermore,the RBE process could significantly improve the grain refining capacity and the proportion of dynamic recrystallization(DRX),of which the maximum reduction of grain size was 88.60%,and the maximum increase of DRX proportion was 55.30%in the cup bottom.The main deformation mechanism of the RBE process was the discontinuous DRX(DDRX),while the continuous DRX(CDRX)was also occurred in the cup transition.Compared with the CBE sample,the texture of the cup bottom was weakened for the RBE sample.The microhardness value of the RBE sample was higher than that of the CBE sample,which can be attributed to the grain refinement strengthening. | Xin Che Qiang Wang Beibei Dong Mu Meng Zhi Gao Kai Liu Jin Ma Fulai Yang Zhiming Zhang | 2021 | Journal of Magnesium and Alloys2021，9，5： | 4 |
| 12 | Two-dimensional coupled mathematical modeling of fluvial processes with intense sediment transport and rapid bed evolution显示文摘Alluvial rivers may experience intense sediment transport and rapid bed evolution under a high flow regime,for which traditional decoupled mathematical river mod-els based on simplified conservation equations are not applicable. A two-dimen-sional coupled mathematical model is presented,which is generally applicable to the fluvial processes with either intense or weak sediment transport. The governing equations of the model comprise the complete shallow water hydrodynamic equa-tions closed with Manning roughness for boundary resistance and empirical rela-tionships for sediment exchange with the erodible bed. The second-order Total-Variation-Diminishing version of the Weighted-Average-Flux method,along with the HLLC approximate Riemann Solver,is adapted to solve the governing equations,which can properly resolve shock waves and contact discontinuities. The model is applied to the pilot study of the flooding due to a sudden outburst of a real glacial-lake. | YUE ZhiYuan CAO ZhiXian LI Xin CHE Tao | 2008 | Science China(Physics,Mechanics & Astronomy)2008，51，9： | 4 |

| 14 | Effectiveness of a hydroxynaphthoquinone fraction from Arnebia euchroma in rats with experimental colitis显示文摘AIM:To evaluate the potential effectiveness of hydroxynaphthoquinone mixture(HM)in rats with 2,4,6-trinitrobenzene sulfonic acid(TNBS)-induced colitis.METHODS:Colitis was induced by intracolonic administration of TNBS(80 mg/kg,dissolved in 50%ethanol).Rats were treated daily for 7 d with HM(2.5,5,10 mg/kg)and mesalazine 100 mg/kg 24 h after TNBS instillation.Disease progression was monitored daily by observation of clinical signs and body weight change.At the end of the experiment,macroscopic and histopathologic lesions of rats were scored,and myeloperoxidase(MPO)activity was determined.We also determined inflammatory cytokine tumor necrosis factor(TNF)-αlevel by ELISA,Western blotting and immunochemistry to explore the potential mechanisms of HM.RESULTS:After intracolonic instillation of TNBS,animals developed colitis associated with soft stool,diarrhea and marked colonic destruction.Administration of HM significantly attenuated clinical and histopathologic severity of TNBS-induced colitis in a dose-dependent manner.It abrogated body weight loss,diarrhea and inflammation,decreased macroscopic damage score,and improved histological signs,with a significant reduction of inflammatory infiltration,ulcer size and the severity of goblet cell depletion(all P<0.05 vs TNBS alone group).HM could reduce MPO activity.In addition,it also decreased serum TNF-αlevel and down-regulated TNF-αexpression in colonic tissue.This reduction was statistically significant when the dose of HM was 10 mg/kg(P<0.05 vs TNBS alone group),and the effect was comparable to that of mesalazine and showed no apparent adverse effect.The underlying mechanism may be associated with TNF-αinhibition.CONCLUSION:These findings suggest that HM possesses favourable therapeutic action in TNBS-induced colitis,which provides direct pharmacological evidence for its clinical application. | Hua-Ying Fan Zi-Liang Zhang Ke Liu Ming-Yan Yang Wei-Hong Lv Xin Che Hui Xu Wei-Wei Song | 2013 | World Journal of Gastroenterology2013，19，48： | 3 |
| 15 | Glucose oxidase as a blocking agent-based signal amplification strategy for the fabrication of label-free amperometric immunosensors显示文摘An effective electrochemical signal amplification strategy based on enzyme membrane modification and redox probe immobilization was proposed to construct an amperometric immunosensor.L-cysteine@ferrocene functionalized chitosan,which possessed not only efficient redox-activity but also excellent film-forming ability,was coated on the bare glass carbon electrode. Moreover,the thiol groups(SH)in the ferrocenyl compound were used for gold nanoparticles immobilization via the strong bonding interaction,which could further be utilized for the immobilization of antibody biomolecules with well-retained bioactivities.Finally,glucose oxidase(GOD)as the enzyme membrane was employed to block the possible remaining active sites and avoid the nonspecific adsorption.With the excellent electrocatalytic properties of GOD towards glucose,the amplification of antigen-antibody interaction and the enhanced sensitivity could be achieved.Under the optimal conditions,the linear range of the proposed immunosensor for the determination of carcinoembryonic antigen(CEA)was from 0.05 to 100 ng/mL with a detection limit of 0.02 ng/mL(S/N=3).Moreover,the immunosensor exhibited good selectivity,stability and reproducibility, which provided a promising potential for clinical immunoassay. | SONG ZhongJu YUAN Ruo CHAI YaQin CHE Xin LV Ping | 2011 | Science China Chemistry2011，54，3： | 3 |

| 17 | Optical and Radiative Properties of Aerosols during a Severe Haze Episode over the North China Plain in December 2016显示文摘The optical and radiative properties of aerosols during a severe haze episode from 15 to 22 December 2016 over Beijing, Shijiazhuang, and Jiaozuo in the North China Plain were analyzed based on the ground-based and satellite data, meteorological observations, and atmospheric environmental monitoring data. The aerosol optical depth at 500 nm was < 0.30 and increased to > 1.4 as the haze pollution developed. The ?ngstr?m exponent was > 0.80 for most of the study period. The daily single-scattering albedo was > 0.85 over all of the North China Plain on the most polluted days and was > 0.97 on some particular days. The volumes of fine and coarse mode particles during the haze event were approximately 0.05–0.21 and 0.01–0.43 μm3, respectively—that is, larger than those in the time without haze. The daily absorption aerosol optical depth was about 0.01–0.11 in Beijing, 0.01–0.13 in Shijiazhuang, and0.01–0.04 in Jiaozuo, and the average absorption ?ngstr?m exponent varied between 0.6 and 2.0. The aerosol radiative forcing at the bottom of the atmosphere varied from –23 to –227, –34 to –199, and –29 to –191 W m–2 for the whole haze period, while the aerosol radiative forcing at the top of the atmosphere varied from –4 to –98, –10 to –51,and –21 to –143 W m–2 in Beijing, Shijiazhuang, and Jiaozuo, respectively. Satellite observations showed that smoke,polluted dust, and polluted continental components of aerosols may aggravate air pollution during haze episodes. The analysis of the potential source contribution function and concentration-weighted trajectory showed that the contribution from local emissions and pollutants transport from upstream areas were 190–450 and 100–410 μg m^(–3), respectively. | Yu ZHENG Huizheng CHE Leiku YANG Jing CHEN Yaqiang WANG Xiangao XIA Hujia ZHAO Hong WANG Deying WANG Ke GUI Linchang AN Tianze SUN Jie YU Xiang KUANG Xin LI Enwei SUN Dapeng ZHAO Dongsen YANG Zengyuan GUO Tianliang ZHAO Xiaoye ZHANG | 2017 | Journal of Meteorological Research2017，31，6： | 2 |
| 18 | Recent Progress in Atmospheric Chemistry Research in China: Establishing a Theoretical Framework for the “Air Pollution Complex”显示文摘Atmospheric chemistry research has been growing rapidly in China in the last 25 years since the concept of the“air pollution complex”was first proposed by Professor Xiaoyan TANG in 1997.For papers published in 2021 on air pollution(only papers included in the Web of Science Core Collection database were considered),more than 24000 papers were authored or co-authored by scientists working in China.In this paper,we review a limited number of representative and significant studies on atmospheric chemistry in China in the last few years,including studies on(1)sources and emission inventories,(2)atmospheric chemical processes,(3)interactions of air pollution with meteorology,weather and climate,(4)interactions between the biosphere and atmosphere,and(5)data assimilation.The intention was not to provide a complete review of all progress made in the last few years,but rather to serve as a starting point for learning more about atmospheric chemistry research in China.The advances reviewed in this paper have enabled a theoretical framework for the air pollution complex to be established,provided robust scientific support to highly successful air pollution control policies in China,and created great opportunities in education,training,and career development for many graduate students and young scientists.This paper further highlights that developing and low-income countries that are heavily affected by air pollution can benefit from these research advances,whilst at the same time acknowledging that many challenges and opportunities still remain in atmospheric chemistry research in China,to hopefully be addressed over the next few decades. | Tong ZHU Mingjin TANG Meng GAO Xinhui BI Junji CAO Huizheng CHE Jianmin CHEN Aijun DING Pingqing FU Jian GAO Yang GAO Maofa GE Xinlei GE Zhiwei HAN Hong HE Ru-Jin HUANG Xin HUANG Hong LIAO Cheng LIU Huan LIU Jianguo LIU Shaw Chen LIU Keding LU Qingxin MA Wei NIE Min SHAO Yu SONG Yele SUN Xiao TANG Tao WANG Tijian WANG Weigang WANG Xuemei WANG Zifa WANG Yan YIN Qiang ZHANG Weijun ZHANG Yanlin ZHANG Yunhong ZHANG Yu ZHAO Mei ZHENG Bin ZHU Jiang ZHU | 2023 | Advances in Atmospheric Sciences2023，40，8： | 2 |
| 19 | Low-cycle fatigue behavior of permanent mold cast and die-cast Al-Si-Cu-Mg alloys显示文摘Fatigue failure is one of the main failure forms of Al-Si-Cu-Mg aluminum alloys.To feature their mechanical aspect of fatigue behavior,the low-cycle fatigue behavior of permanent mold cast and die-cast Al-Si-Cu-Mg alloys at room temperature was investigated.The experimental results show that both permanent mold cast and die-cast Al-Si-Cu-Mg alloys mainly exhibit cyclic strain hardening.At the same total strain amplitude,the die-cast Al-Si-Cu-Mg alloy shows higher cyclic deformation resistance and longer fatigue life than does the permanent mold cast Al-Si-Cu-Mg alloy.The relationship between both elastic and plastic strain amplitudes with reversals to failure shows a monotonic linear behavior,and can be described by the Basquin and Coffin-Manson equations,respectively. | Chen Lijia Wang Di Che Xin Li Feng | 2012 | China Foundry2012，9，1： | 2 |
| 20 | Expression of Sex-Related Genes in Chicken Embryos During Male-to-Female Sex Reversal Exposure to Diethylstilbestrol显示文摘Sex emerges out of a delicate dance between a variety of promale, anti-male, and possibly profemale genes. To investigate the role that sex-related genes play in sex determination and gonadal differentiation of fowl, we constructed a male-to- female sex-reversal model of chick induced by diethylstilbestrol (DES) at onset of incubation (E0). The results of semi- quantitative PCR showed that the expression of Sf1, the orphan nuclear receptor steroidogenic factor-1 gene, was put forward from E7d to E5d and up-regulated during E5-7d; the Dmrt1, the double sex and the Mab-3 related to transcription factor 1 gene, was down-regulated during E3-7d. Meanwhile, anti-Müllerian hormone gene (Amh) expressed at a similar level in the genetic females and sex-reversal females before E7d, while no expression products of the three female-specific genes Wpkci, Fet1 and Foxl2 were detected in male-to-female embryos. These findings suggest that the expression of some certain sex-related genes, induced by the exogenous estrogen during period of sex determination and gonadal differentiation, results in the male-to-female sex reversal. Moreover, high activity of Sf1 gene during E5-7d might be related to the profemale process, while low activity of Dmrt1 gene during E3-5d might be anti-male. The expression activity of Amh gene might only contribute to the promale process after E7d, however, it is possibly not an anti-female gene in chick embryos. | FANG Li-xiu XIN Rui CHE Yi XU Shi-qing | 2013 | Journal of Integrative Agriculture2013，12，1： | 2 |
