| 1 | Cloning and expression profiles of 15 genes encoding WRKY transcription factor in wheat (Triticum aestivem L.)显示文摘WRKY proteins are involved in various physiological processes,including biotic and abiotic stress responses,hormone responses and development.However,no systematic identification,expression and function analysis of WRKY genes in wheat were reported.In this study,we isolated 15 wheat cDNAs with complete open reading frame(ORF)encoding putative WRKY proteins using in silico cloning.Phylogenetic analysis indicated that the 15 wheat WRKY genes belonged to three major WRKY groups.Expression analysis revealed that most genes expressed drastically in leaf,except TaWRKY10 which expressed in crown intensively.Four genes were strongly up-reg-ulated with the senescence of leaves.Eight genes were responsive to low temperature,high temperature,NaCl or PEG treatment.More-over,dierential expression patterns were also observed between wheat hybrid and its parents,and some genes were more responsive to PEG treatment in the hybrid.These results demonstrated that wheat WRKY genes are involved in leaf senescing and abiotic stresses.And the changed expression of these WRKY genes in hybrid might contribute to the heterosis by improving the stress tolerance in hybrids. | Hualing Wu Zhongfu Ni Yingyin Yao Ganggang Guo Qixin Sun | 2008 | Progress in Natural Science:Materials International2008，18，6： | 34 |
| 2 | Sequence sedimentary evolution and reservoir distribution in the third and fourth members of Sinian Dengying Formation,Gaomo area,Sichuan Basin,SW China显示文摘Based on comprehensive analysis of cores,thin sections,logging and seismic data,the sequence stratigraphy and sedimentary evolution of the third and fourth members of Sinian Dengying Formation(Deng 3 and Deng 4 members for short)in the Gaomo area of Sichuan Basin were investigated,and the favorable zones for reservoir development in the Deng 3 Member and Deng 4 Member were predicted.(1)Two Type I and one Type II sequence boundaries are identified in the Deng 3 and Deng 4 members.Based on the identified sequence boundaries,the Deng 3 and Deng 4 members can be divided into two third order sequences SQ3 and SQ4,which are well-developed,isochronal and traceable in this area;the SQ3 thins from west to the east,and the SQ4 thins from northwest to southeast.(2)The sedimentary environment from the depositional period of SQ3 to SQ4 has experienced the evolution from mixed platform to rimmed platform,and the platform rimmed system on the west side is characterized by the development of platform margin microbial mound and grain shoal assemblages.The intraplatform area is a restricted platform facies composed of a variety of dolomites,and there are local micro-geomorphic highlands of different scales and scattered intraplatform mounds and shoals.(3)The Deng 4 Member reservoirs,with obvious facies-controlled characteristic,are mainly distributed in the upper part of high-frequency upward shallow cycle and the high-stand systems tract of the third-order sequence vertically,and are more developed in the platform margin belt than in the intraplatform belt,and more developed in the Gaoshiti platform margin belt than in the west Suining platform margin belt on the plane.(4)Three types of favorable reservoir zones of Deng 4 Member have been finely delineated with 3D seismic data;among them,the mound and shoal facies zones developed in the ancient highlands of the intraplatform are the first choice for the next exploration and development of the Deng 4 Member. | TAN Lei LIU Hong CHEN Kang NI Hualing ZHOU Gang ZHANG Xuan YAN Wei ZHONG Yuan LYU Wenzheng TAN Xiucheng ZHANG Kun | 2022 | Petroleum Exploration and Development2022，49，5： | 1 |
| 3 | Sequence-lithofacies paleogeographic characteristics and petroleum geological significance of Lower Permian Qixia Stage in Sichuan Basin and its adjacent areas,SW China显示文摘Through the analysis of logging,field outcrops,cores and geochemical data,and based on the study of the relationships between sea level changes,sequence filling,paleo-geomorphy and lithofacies,the sequence lithofacies paleo-geography and evolution process of the Lower Permian Liangshan-Qixia Formation(Qixia Stage for short)in Sichuan Basin and its surrounding areas are restored.The Qixia Stage can be divided into three third-order sequences,in which SQ0,SQ1 and SQ2 are developed in the depression area,and SQ1 and SQ2 are only developed in other areas.The paleo-geomorphy reflected by the thickness of each sequence indicates that before the deposition of the Qixia Stage in the Early Permian,the areas surrounding the Sichuan Basin are characterized by“four uplifts and four depressions”,namely,four paleo-uplifts/paleo-lands of Kangdian,Hannan,Shennongjia and Xuefeng Mountain,and four depressions of Chengdu-Mianyang,Kangdian front,Jiangkou and Yichang;while the interior of the basin is characterized by“secondary uplifts,secondary depressions and alternating convex-concave”.SQ2 is the main shoal forming period of the Qixia Formation,and the high-energy mound shoal facies mainly developed in the highs of sedimentary paleo-geomorphy and the relative slope break zones.The distribution of dolomitic reservoirs(dolomite,limy dolomite and dolomitic limestone)has a good correlation with the sedimentary geomorphic highs and slope break zones.The favorable mound-shoal and dolomitic reservoirs are distributed around depressions at platform-margin and along highs and around sags in the basin.It is pointed out that the platform-margin area in western Sichuan Basin is still the key area for exploration at present;while areas around Chengdu-Mianyang depression and Guangwang secondary depression inside the platform and areas around sags in central Sichuan-southern Sichuan are favorable exploration areas for dolomitic reservoirs of the Qixia Formation in the next step. | LI Minglong TAN Xiucheng YANG Yu NI Hualing LUO Bing WEN Long ZHANG Benjian XIAO Di XU Qiang | 2022 | Petroleum Exploration and Development2022，49，6： | 0 |
