| 2 | The Coix Genome Provides Insights into Panicoideae Evolution and Papery Hull Domestication显示文摘Coix is a grass crop domesticated as early as the Neolithic era.It is still widely cultivated for both highly nutritional food and medicinal use.However,the genetic study and breeding of this crop are hindered by the lack of a sequenced genome.Here,we report de novo sequencing and assembly of the 1619-Mb genome of Coix,and annotation of 75.39%repeats and 39629 protein-coding genes.Comparative genomics analysis showed that Coix is more closely related to sorghum than maize,but intriguingly only Coix and maize had a recent genome duplication event,which was not detected in sorghum.We further constructed a genetic map and mapped several important traits,especially the strength of hull.Selection of papery hull(thin:easy dehulling)from the stony hull(thick:difficult dehulling)in wild progenitors was a key step in Coix domestication.The papery hull makes seed easier to process and germinate.Anatomic and global transcriptome analysis revealed that the papery hull is a result of inhibition of cell division and wall biogenesis.We also successfully demonstrated that seed hull pressure resistance is controlled by two major quantitative trait loci(QTLs),which are associated with hull thickness and color,respectively.The two QTLs were further fine mapped within intervals of 250 kb and 146 kb,respectively.These resources provide a platform for evolutionary studies and will facilitate molecular breeding of this important crop. | Chao Guo Yanan Wang Aiguo Yang Jun He Chaowen Xiao Shanhua Lv Fengming Han Yibing Yuan Yuan Yuan Xiaolong Dong Juan Guo YawenYang-Hailan Liu Ningzhi Zuo Yaxi Hu Kangxu Zhao Zhengbo Jiang Xing Wang Tingting Jiang Yaou Sherf Moju Cao Yuan Wang Zhaobo Long Tingzhao Rong Luqi Huang Shufeng Zhou | 2020 | Molecular Plant2020，13，2： | 11 |
| 3 | Geological characteristics of shale rock system and shale oil exploration breakthrough in a lacustrine basin:A case study from the Paleogene 1st sub-member of Kong 2 Member in Cangdong sag,Bohai Bay Basin,China显示文摘A deep understanding of the basic geologic characteristics of the fine-grained shale layers in the Paleogene 1 st sub-member of Kong 2 Member(Ek_2~1) in Cangdong sag, Bohai Bay Basin, is achieved through observation of 140 m continuous cores and systematic analysis of over 1 000 core samples from two wells. Basic geological conditions for shale oil accumulation are proposed based on the unconventional geological theory of oil and gas. The shale rock system mainly developed interbedded formation of felsic shale, calcareous and dolomitic shale and carbonates; high quality hydrocarbon source rock formed in the stable and closed environment is the material base for shale oil enrichment; intergranular pores in analcite, intercrystalline pores in dolomite and interlayer micro-fractures make tight carbonate, calcareous and dolomitic shale and felsic shale effective reservoirs, with brittle mineral content of more than 70%; high abundance laminated shale rock in the lower section of Ek_2~1 is rich in shale oil, with a total thickness of 70 m, burial depth between 2 800 to 4 200 m, an average oil saturation of 50%, a sweet spot area of 260 km^2 and predicted resources of over 5×10~8 t. Therefore, this area is a key replacement domain for oil exploration in the Kongdian Formation of the Cangdong sag. At present, the KN9 vertical well has a daily oil production of 29.6 t after fracturing with a 2 mm choke. A breakthrough of continental shale oil exploration in a lacustrine basin is expected to be achieved by volume fracturing in horizontal wells. | ZHAO Xianzheng ZHOU Lihong PU Xiugang JIN Fengming HAN Wenzhong XIAO Dunqing CHEN Shiyue SHI Zhannan ZHANG Wei YANG Fei | 2018 | Petroleum Exploration and Development2018，45，3： | 8 |
| 4 | Theories,technologies and practices of lacustrine shale oil exploration and development:A case study of Paleogene Kongdian Formation in Cangdong sag,Bohai Bay Basin,China显示文摘As the main factors affecting stable and high production and the production regularity of lacustrine shale oil are unclear,the theoretical understandings,key exploration and development technologies,development effect and production regularity of lacustrine shale oil have been analyzed and summarized based on 700 m cores taken systematically from Paleogene Kong 2 Member of 4 wells in Cangdong sag,over 100000 analysis data and formation testing data.Three theoretical understandings on shale oil enrichment and high production have been reached:(1)High-quality shale with“three highs and one low”is the material base for shale oil enrichment.(2)Medium-slightly high thermal evolution degree is the favorable condition for shale oil enrichment.(3)Laminar felsic shale is the optimal shale layer for oil enrichment in semi-deep lake facies.Key exploration and development technologies such as shale oil enrichment layer and area evaluation and prediction,horizontal well pattern layout,shale oil reservoir fracturing,optimization of shale oil production regime have been established to support high and stable shale oil production.Under the guidance of these theoretical understandings and technologies,shale oil in Cangdong sag has achieved high and stable production,and 4 of them had the highest production of over 100 tons a day during formation testing.In particular,Well GY5-1-1 L had a daily oil production of 208 m^(3).By April,2022,the 28 wells combined have a stable oil production of 300–350 tons a day,and have produced 17.8×10^(4) t of oil cumulatively.It is found that the shale oil production of horizontal well declines exponentially in natural flow stage,and declines in step pattern and then tends stable in the artificial lift stage.Proportion of light hydrocarbons in produced shale oil is in positive correlation with daily oil production and decreases regularly during production test. | ZHAO Xianzheng ZHOU Lihong PU Xiugang JIN Fengming HAN Wenzhong SHI Zhannan CHEN Changwei JIANG Wenya GUAN Quansheng XU Jing LIU Xuewei ZHANG Wei MA Jianying | 2022 | Petroleum Exploration and Development2022，49，3： | 4 |
| 5 | Geological characteristics and key exploration technologies of continental shale oil sweet spots: A case study of Member 2 of Kongdian Formation in the Cangdong sag in the Huanghua depression, Bohai Bay Basin显示文摘Under the general trend of stepping-up oil and gas exploration and development in China,the unconventional oil and gas resources such as shale oil and gas have become an important alternative.Abundant continental shale oil resources are developed in Member 2 of Kongdian Formation(Ek2)of the Cangdong sag in the Huanghua depression of the Bohai Bay Basin which has complex structure,strong heterogeneity,and large buried depth,thus,the geological characteristic of shale oil accumulation and key exploration technologies are investigated on base of the system coring of 635.8 m,centimeter-level fine description and analysis of over ten thousand samples,therefore,the“four accurate”technologies have been developed,including the accurate selection of sweet spot areas,accurate drilling of sweet spot layers,accurate fracturing of sweet spot layers and accurate measure of fracture-rich sections.The results show that the continental shale strata in Member 2 of Kongdian Formation can be divided into three types:felsic shale,limy dolomitic shale and mixed shale.The Member 2 of Kongdian Formation is characterized by diverse mineral components,abundant laminae,good source rocks and medium thermal evolution degree,tight reservoir with rich micropore and microfractures,high oil saturation and brittle mineral content,indicating good prospect of shale oil exploration.Through sedimentological study,TOC and Ro evaluation,brittle mineral calculation,and seismic fusion inversion,a total of 126 km^(2) of Class I sweet spots in Member 2 of Kongdian Formation was delineated comprehensively,which guides horizontal well deployment(Well GD1701H and Well GD1702H).The drilling rate of sweet spot of these two horizontal wells is up to 96%by tracing thin layer through fine calibration,locating compartment through fine inversion,ensuring window entry through precise positioning,and tracking sweet spot through adjustment.The “one-excellent and five-highs”criterion is used to select perforation points to realize differential designs of fracturing intervals and clusters.Micro-seismic and potentiometry monitoring show that the artificial fractures formed by volumetric fracturing are 300e400 m long and 120 m high,and control a volume of about 0.07 km^(3).The maximum daily oil production of two horizontal wells is 48 t and 66 t respectively to realize the economic exploitation of shale oil reserves controlled by fractures.The shale oil exploration in Member 2 of Kongdian Formation shows that the continental shale oil has great potential of exploration and development,and the above technologies are critical and effective for shale oil efficient recovery. | Xianzheng Zhao Xiugang Pu Fengming Jin Wenzhong Han Zhannan Shi Aibing Cai Aiguo Wang Quansheng Guan Wenya Jiang Wei Zhang | 2019 | Petroleum Research2019，4，2： | 2 |
| 6 | Sweet spot evaluation and exploration practice of lacustrine shale oil of the second member of Kongdian Formation in Cangdong sag, Bohai Bay Basin显示文摘Based on core,thin section,X-ray diffraction,rock pyrolysis,CT scanning,nuclear magnetic resonance and oil testing data,the macro and micro components,sedimentary structure characteristics,of Paleogene Kong 2 Member in Cangdong sag of Huanghua depression and evaluation standard and method of shale oil reservoir were studied to sort out the best shale sections for shale oil horizontal wells.According to the dominant rock type,rhythmic structure and logging curve characteristics,four types of shale lithofacies were identified,namely,thin-layered dolomitic shale,lamellar mixed shale,lamellar felsic shale,and bedded dolomitic shale,and the Kong 21 sub-member was divided into four quasi-sequences,PS1 to PS4.The PS1 shale has a porosity higher than 6%,clay content of less than 20%,and S1 of less than 4 mg/g;the PS2 shale has well-developed laminar structure,larger pore and throat size,better connectivity of pores and throats,high contents of TOC and movable hydrocarbon,S1 of over 4 mg/g,clay content of less than 20%,and porosity of more than 4%;PS3 shale has S1 value higher than 6 mg/g and clay content of 20%-30%,and porosity of less than 4%;and PS4 shale has lower TOC content and low oil content.Shale oil reservoir classification criterion based on five parameters,free hydrocarbon content S1,shale rhythmic structure,clay content,TOC and porosity,was established.The evaluation method of shale oil sweet spot by using the weighted five parameters,and the evaluation index EI were proposed.Through comprehensive analysis,it is concluded that PS2 is best in quality and thus the dual geological and engineering sweet spot of shale oil,PS3 and PS1 come next,the former is more geologic sweet spot,the latter more engineering sweet spot,and PS4 is the poorest.Several vertical and horizontal wells drilled in the PS2 and PS3 sweet spots obtained high oil production.Among them,Well 1701 H has produced stably for 623 days,with cumulative production of over 10000 tons,showing bright exploration prospects of Kong 2 Member shale oil. | HAN Wenzhong ZHAO Xianzheng JIN Fengming PU Xiugang CHEN Shiyue MU Liangang ZHANG Wei SHI Zhannan WANG Hu | 2021 | Petroleum Exploration and Development2021，48，4： | 1 |

| 9 | Multiple characteristic structure fragments scans coupled to high-resolution mass spectrometry strategy for discovering unknown structural analogs of mycotoxins in food显示文摘The cereals and their products,which have been easily infected by fungi and contaminated with mycotoxins,are serious threat to both human and animals alike.And yet,detection of these unknown fungal infection and mycotoxins contaminates remains a great challenge.In this work,a holistic approach based on multiple characteristic structure fragments scans and high-resolution mass spectrometry(HRMS)was proposed for discovering unknown structural analogues of mycotoxins.The structural similarity of the same class of compounds provides a direction for the discovery and identification of unknown structural analogues of mycotoxins.The following steps were carried out:the fragmentation pathways of four types of mycotoxins were elucidated through comprehensive fragment analysis.By the combination of fragmentation pathways,the multiple characteristic structure fragments were screened out,with the common fragments were obtained by Veen diagram.Finally multiple characteristic structure fragments scans were carried out to find the unknown structural analogues of mycotoxins.The approach,first proposed by us,was proved to be effective in discovering and identifying 5 structural analogues of mycotoxins in real samples.It was proved to be a simple,fast and accurate method for early detection of fungal infection and mycotoxin contaminants,even for trace amounts of chemicals in complex matrix,and is of great significance to prevent hazardous substances infection from the food supply chains worldwide. | Dongwei Cui Xiuli Xu Xiujuan Wang Feng Zhang Fengming Chen Tong Liu Han Wang Yuan Zhang Yaxuan Song Xuesong Feng | 2022 | Journal of Future Foods2022，2，2： | 0 |
| 10 | Light from space illuminating the polar silk road显示文摘The rapid decline of Arctic sea ice has been reminding us the significant impacts caused by global warming.However,the other side of the coin is that this opens a window to utilize the Arctic sea routes in the summer seasons,bringing remarkable economic benefits for ocean transportation between Asia and Europe.However,commercial vessels with low ice classes must tackle substantial environmental challenges in the Arctic sea routes,particularly those caused by variable sea ice,even in the melting seasons.Therefore,the science-based support for shipping safety in the Arctic sea routes is being given more prominence.Emerging satellite remote sensing technology plays a critical role in environmental monitoring in the Arctic.This paper reviews state-of-the-art satellite observations on monitoring sea ice and potential applications on supporting shipping activities in the Arctic Ocean.Moreover,we introduced a recently developed system based on satellite observations to support the safe transportation of Chinese cargo vessels in the Arctic northern sea route,demonstrating the efforts by both the science and business communities to promote the development of the polar silk road. | Xiao-Ming Li Yujia Qiu Yacheng Wang Bingqing Huang Haiming Lu Min Chu Han Fu Fengming Hui | 2022 | International Journal of Digital Earth2022，15，1： | 0 |
| 11 | Cycles of fine-grained sedimentation and their influences on organic matter distribution in the second member of Paleogene Kongdian Formation in Cangdong Sag,Bohai Bay Basin,East China显示文摘According to the theory of sequence stratigraphy based on continental transgressive-regressive(T-R)cycles,a 500 m continuous core taken from the second member of Kongdian Formation(Kong 2 Member)of Paleogene in Well G108-8 in the Cangdong Sag,Bohai Bay Basin,was tested and analyzed to clarify the high-frequency cycles of deep-water fine-grained sedimentary rocks in lacustrine basins.A logging vectorgraph in red pattern was plotted,and then a sequence stratigraphic framework with five-order high-frequency cycles was formed for the fine-grained sedimentary rocks in the Kong 2 Member.The high-frequency cycles of fine-grained sedimentary rocks were characterized by using different methods and at different scales.It is found that the fifth-order T cycles record a high content of terrigenous clastic minerals,a low paleosalinity,a relatively humid paleoclimate and a high density of laminae,while the fifth-order R cycles display a high content of carbonate minerals,a high paleosalinity,a dry paleoclimate and a low density of laminae.The changes in high-frequency cycles controlled the abundance and type of organic matter.The T cycles exhibit relatively high TOC and abundant endogenous organic matters in water in addition to terrigenous organic matters,implying a high primary productivity of lake for the generation and enrichment of shale oil. | ZHAO Xianzheng PU Xiugang YAN Jihua JIN Fengming SHI Zhannan CHAI Gongquan HAN Wenzhong LIU Yan JIANG Wenya CHEN Changwei ZHANG Wei FANG Zheng XIE Delu | 2023 | Petroleum Exploration and Development2023，50，3： | 0 |
| 12 | Development and exploration practice of the concept of hydrocarbon accumulation in rifted-basin troughs: A case study of Paleogene Kongdian Formation in Cangdong sag, Bohai Bay Basin显示文摘Based on the merged 3 D seismic data, well logging, formation testing, analysis and testing data, the structural evolution, sedimentary reservoirs, thermal evolution of source rocks were investigated of Paleogene Kongdian Formation in the trough area of Cangdong sag, Bohai Bay Basin. A conventional-unconventional hydrocarbon accumulation pattern in the trough area of rifted basin was revealed. The reservoir forming elements in the trough area of Cangdong sag have a zonation feature in terms of reservoirs and source rocks. There are two types of reservoir forming models, primary trough and reformed trough. The formation and evolution of trough controlled the orderly distribution of conventional oil to unconventional oil in the trough. Particularly, structural reservoirs occur in the upper part of the trough, stratigraphic-lithologic reservoirs are likely to form in the delta front deposits at the outer ring of trough, the middle ring transitional belt is the favorable site for tight oil reservoirs, while the fine grain deposits zone in the inner ring is shale oil and gas exploration area. The study has pointed out the new domains and directions for searching reserves in the secondary exploration of mature oilfields. | ZHAO Xianzheng ZHOU Lihong PU Xiugang JIN Fengming JIANG Wenya XIAO Dunqing HAN Wenzhong | 2018 | Petroleum Exploration and Development2018，45，6： | 0 |
| 13 | Avian influenza viruses suppress innate immunity by inducingtrans-transcriptional readthrough via SSU72显示文摘Innate immunity plays critical antiviral roles. The highly virulent avian influenza viruses (AIVs) H5N1, H7N9, and H5N6 can betterescape host innate immune responses than the less virulent seasonal H1N1 virus. Here, we report a mechanism by whichtranscriptional readthrough (TRT)-mediated suppression of innate immunity occurs post AIV infection. By using cell lines, mouselungs, and patient PBMCs, we showed that genes on the complementary strand (“trans” genes) influenced by TRT were involved inthe disruption of host antiviral responses during AIV infection. The trans-TRT enhanced viral lethality, and TRT abolishmentincreased cell viability and STAT1/2 expression. The viral NS1 protein directly bound to SSU72, and degradation of SSU72 inducedTRT. SSU72 overexpression reduced TRT and alleviated mouse lung injury. Our results suggest that AIVs infection induce TRT byreducing SSU72 expression, thereby impairing host immune responses, a molecular mechanism acting through the NS1-SSU72-trans-TRT-STAT1/2 axis. Thus, restoration of SSU72 expression might be a potential strategy for preventing AIV pandemics. | Yan Zhao Fengming Huang Zhen Zou Yuhai Bi Yang Yang Cong Zhang Qiang Liu Daozhen Shang Yiwu Yan Xiangwu Ju Song Mei Peng Xie Xiao Li Mingyao Tian Shuguang Tan Huijun Lu Zongsheng Han Kangtai Liu Yuqing Zhang Junbo Liang Zhu Liang Qingchao Zhang Jiahui Chang William JLiu Cong Feng Tanshi Li Michael Q.Zhang Xiaoyue Wang George FGao Yingxia Liu Ningyi Jin Chengyu Jiang | 2022 | Cellular & Molecular Immunology2022，19，6： | 0 |
