| 1 | A journey to understand wheat Fusarium head blight resistance in the Chinese wheat landrace Wangshuibai显示文摘Fusarium head blight(FHB) or scab caused by Fusarium graminearum is a major threat to wheat production in China as well as in the world. To combat this disease, multiple efforts have been carried out internationally. In this article, we review our long-time effort in identifying the resistance genes and dissecting the resistance mechanisms by both forward and reverse genetics approaches in the last two decades. We present recent progress in resistance QTL identification, candidate functional gene discovery, marker-assisted improvement of FHB resistant varieties, and findings in investigating association of signal molecules, such as Ca^(++),SA, JA, and ET, with FHB response, with the assistance from rapidly growing genomics platforms. The information will be helpful for designing novel and efficient approaches to curb FHB. | Haiyan Jia Jiyang Zhou Shulin Xue Guoqiang Li Haisheng Yan Congfu Ran Yiduo Zhang Jinxing Shi Li Jia Xin Wang Jing Luo Zhengqiang Ma | 2018 | The Crop Journal2018，6，1： | 24 |
| 2 | Discrimination of abiogenic and biogenic alkane gases显示文摘We have combined the analytical data of the carbon isotope distribution pattern, R/Ra and CH4/3He values of abiogenic and biogenic (referring to the thermogenic and bacterial or microbial) alkane gases in China with those of alkane gases from USA, Russia, Germany, Australia and other countries. Four discrimination criteria are derived from this comparative study: 1) Carbon isotopic composition is generally greater than -30‰ for abiogenic methane and less than -30‰ for biogenic methane; 2) Abiogenic alkane gases have a carbon isotopic reversal trend (δ 13C1> δ 13C2> δ 13C3> δ 13C4) with δ 13C1>-30‰ in general; 3) Gases with R/Ra >0.5 and δ 13C11 δ 13C2>0 are of abiogenic origin; 4) Gases (meth- ane) with CH4/3He≤106 are of abiogenic origin, whereas gases with CH4/3He≥1011 are of biogenic origin. | DAI JinXing ZOU CaiNeng ZHANG ShuiChang LI Jian NI YunYan HU GuoYi LUO Xia TAO ShiZhen ZHU GuangYou MI JingKui LI ZhiSheng HU AnPing YANG Chun ZHOU QingHua SHUAI YanHua ZHANG Ying MA ChengHua | 2008 | Science China Earth Sciences2008，51，12： | 17 |
| 3 | 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 |

| 13 | Overexpression of maize GOLDEN2 in rice and maize calli improves regeneration by activating chloroplast development显示文摘Golden2(G2), a member of the GARP transcription factor superfamily, regulates several biological processes and phytohormone signaling pathways in plants. In this study, we used a rice codon-optimized maize G2 gene(rZmG2) to improve the regeneration efficiency of rice and maize calli for genetic transformation. We isolated a promoter driving strong and callus-specific expression from rice to drive rZmG2 transcription from a transgene after transformation of two indica and two japonica rice cultivars. The resulting rZmG2 transgenic calli turned green in advance at the differentiation stage, thus significantly raising the regeneration rates of the transgenic indica and japonica rice plants relative to control transformations. Similar effect of this gene on improving maize transformation was also observed. Transcriptome sequencing and RT-qPCR analyses showed that many rice genes related to chloroplast development and phytohormones are upregulated in rZmG2-transgenic calli. These results demonstrate that rZmG2 can promote embryogenic callus differentiation and improve regeneration efficiency by activating chloroplast development and phytohormone pathways. We also established a heat-inducible Cre/loxP-based gene-excision system to remove rZmG2 and the antibiotic selectable gene after obtaining the transgenic plants. This study provides a useful tool for functional genomics work and biotechnology in plants. | Wanni Luo Jiantao Tan Tie Li Ziting Feng Zhi Ding Xianrong Xie Yuanling Chen Letian Chen Yao-Guang Liu Qinlong Zhu Jinxing Guo | 2023 | Science China(Life Sciences)2023，66，2： | 0 |
| 14 | Elevated carbon dioxide stimulates nitrous oxide emission in agricultural soils: A global meta-analysis显示文摘Elevated carbon dioxide (CO_(2))(e CO_(2)) has been shown to affect the nitrous oxide (N_(2)O) emission from terrestrial ecosystems by altering the interaction of plants,soils,and microorganisms.However,the impact of e CO_(2) on the N_(2)O emission from agricultural soils remains poorly understood.This meta-analysis summarizes the effect of e CO_(2) on N_(2)O emission in agricultural ecosystems and soil physiochemical and biological characteristics using 50 publications selected.The e CO_(2) effect values,which equal to the percentage changes of N_(2)O emission under e CO_(2),were calculated based on the natural logarithm of the response ratio to e CO_(2).We found that e CO_(2) significantly increased N_(2)O emission (by 44%),which varied depending on experimental conditions,agricultural practices,and soil properties.In addition,e CO_(2) significantly increased soil water-filled pore space (by 6%),dissolved organic carbon content (by11%),and nitrate nitrogen content (by 13%),but significantly reduced soil p H (by 1%).Moreover,e CO_(2) significantly increased soil microbial biomass carbon(by 28%) and soil microbial biomass nitrogen (by 7%) contents.Additionally,e CO_(2) significantly increased the abundances of ammonia-oxidizing bacteria(AOB) amo A (by 21%),nir K (by 15%),and nir S (by 15%),but did not affect the abundances of ammonia-oxidizing archaea (AOA) amo A and nos Z.Our findings indicate that e CO_(2) substantially stimulates N_(2)O emission in agroecosystems and highlight that optimization of nitrogen management and agronomic options might suppress this stimulation and aid in reducing greenhouse effect. | Yilin DU Xinyu GUO Jinxing LI Yuankun LIU Jipeng LUO Yongchao LIANG Tingqiang LI | 2022 | Pedosphere2022，32，1： | 0 |
| 15 | Disease X Testing:The results of an international external quality assessment exercise显示文摘The United Nations Secretary-General Mechanism(UNSGM)for investigation of the alleged use of chemical and biological weapons is the only established international mechanism of this type under the UN.The UNGSM may launch an international investigation,relying on a roster of expert consultants,qualified experts,and analytical laboratories nominated by the member states.Under the framework of the UNSGM,we organized an external quality assurance exercise for nominated laboratories,named the Disease X Test,to improve the ability to discover and identify new pathogens that may cause possible epidemics and to determine their animal origin.The“what-if”scenario was to identify the etiological agent responsible for an outbreak that has tested negative for many known pathogens,including viruses and bacteria.Three microbes were added to the samples,Dabie bandavirus,Mammarenavirus,and Gemella spp.,of which the last two have not been taxonomically named or published.The animal samples were from Rattus norvegicus,Marmota himalayana,New Zealand white rabbit,and the tick Haemaphysalis longicornis.Of the 11 international laboratories that participated in this activity,six accurately identified pathogen X as a new Mammarenavirus,and five correctly identified the animal origin as R.norvegicus.These results showed that many laboratories under the UNSGM have the capacity and ability to identify a new virus during a possible international investigation of a suspected biological event.The technical details are discussed in this report. | Tian Qin Han Zheng Xuelian Luo Wen Zhang Jing Yang Yamin Sun Na Han Yuanhai You Liang Lu Xin Lu Di Xiao Shenshen Jiang Xuexin Hou Jinxing Lu Biao Kan Jianzhong Zhang Jianguo | 2022 | Journal of Biosafety and Biosecurity2022，4，2： | 0 |
| 16 | Electrochemical drilling of small holes by regulating in real-time the electrolyte flowrate in multiple channels显示文摘Electrochemical drilling(ECD)provides an alternative technique for drilling multiple small holes in difficult-to-machine materials in numerous industrial applications such as for aeroengines.The value and fluctuation of electrolyte flowrate can seriously affect the machining stability and hole quality in ECD.In particular,when drilling multiple holes,the distribution and fluctuations of the electrolyte flowrate in each channel could influence the uniformity of the electrolyte flowrate among multiple tube electrodes,thereby affecting the machining stability and the maximum feed rate.Thus,an eight-channel flow control system was developed to measure and regulate in real time the electrolyte flowrate supplied into each individual tube electrode.This paper proposes ECD of small holes with real-time flowrate control to improve the uniformity of electrolyte flowrate in each tube electrode and reduce the fluctuations in the electrolyte flowrate.In single-hole drilling,when the electrolyte flowrate was regulated in real time,the hole quality and machining stability were considerably better than without regulation.This is because the electrolyte flowrate remains basically constant,which stabilizes the flow field.Moreover,by considering the hole profile,it was found that an electrolyte flowrate of 200.0 m L/min can be acceptable for ECD of small holes.When the eight-channel flow control system was used in multiple-hole drilling,the uniformity of the electrolyte flowrate in each tube electrode was obviously improved,which led to a more stable process.Additionally,the maximum feed rate can attain 2.40 mm/min in multiple-hole drilling.Based on these findings,a matrix(5×32)of multiple small holes was successfully fabricated with a satisfactory diameter consistency,as the machining stability and machining efficiency had been enhanced. | Jinxing LUO Xiaolong FANG Tao YANG Di ZHU | 2022 | Chinese Journal of Aeronautics2022，35，5： | 0 |
