| 1 | ^(40)Ar-^(39)Ar dating and geological implication of auriferous altered rocks from the middle-deep section of Q875 gold-quartz vein in Xiaoqinling area, Henan,China显示文摘The 40Ar-39Ar age method is employed in this work to analyze the auriferous altered rocks from the middle-deep section of the Q875 gold-quartz vein in the Xiao-qinling area, and the results show that the main gold deposition of the Q875 occurred in ca. 128-126 Ma. As a typical gold-bearing quartz vein in this gold-rich area, the age data obtained from the Q875 also constrain on the metallogenic time of the lode gold deposits developed in the same geological settings. This geochronological study supplies new evidence for further understanding the timing of gold mineralization, the genesis of gold deposits and the geodynamic settings in Xiaoqinling area. | WANG Yitian, MAO Jingwen, LU Xinxiang & YE AnwangInstitute of Mineral Resources, Chinese Academy of Geological Sciences, Beijing 100037, China Institute of Geological Sciences, Henan Province, Zhengzhou 450053, China Lingbao Bureau of Geology and Mineral | 2002 | Chinese Science Bulletin2002，47，20： | 36 |
| 2 | Inuence of oxytetracycline on the structure and activity of microbial community in wheat rhizosphere soil显示文摘The microbial community composition in wheat rhizosphere was analyzed by detecting colony forming units (CFUs) in agar plates. The total CFUs in rhizosphere were 1.04 × 109/g soil with 9.0 × 108/g bacteria, 1.37 × 108/g actinomyces and 3.6 × 106/g fungi. The 10 dominant bacteria were isolated from wheat rhizosphere and were grouped into genus Bacillus according to their full length 16S rRNA gene sequences. Although belonging to the same genus, the isolated strains exhibited dierent sensitivities to oxytetracycline. When a series of the rhizosphere soil was exposed under various concentrations of oxytetracycline, the microbial community structure was highly aected with significant decline of CFUs of bacteria and actinomyces (22.2% and 31.7% at 10 mg/kg antibiotic, respectively). This inhibition was clearly enhanced with the increase exposure dosage of antibiotic and could not be eliminated during 30 d incubation. There was no obvious inuence of this treatment on fungi population. Among the four soil enzymes (alkaline phosphatase, acidic phosphatase, dehydrogenase and urease), only alkaline phosphatase was sensitive to oxytetracycline exposure with 41.3% decline of the enzyme activity at 10 mg/kg antibiotic and further decrease of 64.3%-80.8% when the dosage over 30 mg/kg. | YANG Qingxiang, ZHANG Jing, ZHU Kongfang, ZHANG Hao College of Life Sciences, Henan Normal University, Xinxiang 453007, China. | 2009 | Journal of Environmental Sciences2009，21，7： | 36 |

| 7 | Dynamics of Wetland Landscape Pattern in Kaifeng City from 1987 to 2002显示文摘It is very significant for urban development and urban wetland protection and utilization to probe into the process and reasons of urban wetland landscape dynamics. Taking the information of remote sensing and detailed land survey data as the basic information sources, with the help of RS and GIS, according to the principles and methods of landscape ecology, this paper analyzed wetland landscape pattern dynamics and its reasons in Kaifeng City, Henan Prov-ince of China, from 1987 to 2002. The results show that the total wetland area in Kaifeng City firstly reduced by 20.1% from 1987 to 1990 and then increased from 1990 to 2002, with an average annual growth rate of 3.3%. At the same time, landscape fragment degree and landscape dominance degree increased, respectively from 0.64 to 0.72 and from 0.3754 to 0.5563, but mean patch area, maximum patch area, patch fractal dimension reduced. As far as single landscape element concerned, from 1987 to 2002, patch area, patch number, patch density, patch shape and patch location changed in varying degrees in all wetland types in Kaifeng City, among which rice field changed most and others relatively less. In the recent 20 years, rice fields, lake wetlands, puddles and ponds had a higher stability, but river and bottomland wetlands were mostly transformed to land use types. The change of wetland landscape pattern was the result of the combined action of the Huanghe (Yellow) River, urban expansion, wide cultivation of rice, and rapid development of fishery. Among them human activities were the main driving factors for wetland landscape changes. | CAO Xinxiang | 2008 | Chinese Geographical Science2008，18，2： | 10 |

| 10 | Identification of an avirulence gene,avrxa5,from the rice pathogen Xanthomonas oryzae pv.oryzae显示文摘Xanthomonas oryzae pv.oryzae,the causal agent of bacterial blight in rice,interacts with rice plants in a gene-for-gene manner.The specificity of the interaction is dictated by avirulence(avr) genes in the pathogen and resistance(R) genes in the host.To date,no avr genes that correspond to recessive R genes have been isolated.We isolated an avrBs3/pthA family gene,avrxa5,from our previously isolated clone p58,which was originally from strain JXOIII.The avrxa5 gene converted the PXO99A strain from compatible to incompatible in rice cultivars containing the recessive xa5 gene,but not in those containing the dominant Xa5 gene.Sequencing indicated that avrxa5,which is highly similar to members of the avrBs3/pthA family,encodes a protein of 1238 amino acid residues with a conserved carboxy-terminal region containing three nuclear localization signals and a transcription activation domain.It has 19.5 34-amino-acid direct repeats,but the 13th amino acid is missing in the fifth and ninth repetitive units.Domain swapping of the repetitive regions between avrxa5 and avrXa7 changed the avirulence specificity of the genes in xa5 and Xa7 rice lines,respectively.This indicates that avrxa5 is distinct from previously characterized avrBs3/pthA members.The specificity of avrxa5 toward recessive xa5 in rice could help us better understand the molecular mechanisms of plant-pathogen specific interactions. | ZOU HuaSong1,ZHAO WenXiang2,ZHANG XiFu3,HAN YangChun2,ZOU LiFang2 & CHEN GongYou1,2* 1School of Agriculture and Biology,Shanghai Jiaotong University,Shanghai 200240,China 2College of Plant Protection,Nanjing Agricultural University/Laboratory for Monitoring and Management for Plant Pests and Diseases,Chinese Ministry of Agriculture,Nanjing 210095,China 3Department of Agronomy,Henan Vocation-Technical Teachers College,Xinxiang 453003,China | 2010 | Science China(Life Sciences)2010，53，12： | 9 |
| 11 | Nucleocytoplasmic Trafficking of the Arabidopsis WD40 Repeat Protein XIW1 Regulates ABI5 Stability and Abscisic Acid Responses显示文摘WD40 repeat-containing proteins(WD40 proteins)serve as versatile scaffolds for protein-protein interac-tions,modulating a variety of cellular processes such as plant stress and hormone responses.Here we report the identification of a WD40 protein,XIW1(for XPO1-interacting WD40 protein 1),which positively regulates the abscisic acid(ABA)response in Arabidopsis.XIW1 is located in the cytoplasm and nucleus.We found that it interacts with the nuclear transport receptor XPO1 and is exported by XPO1 from the nucleus.Mutation of XIW1 reduces the induction of ABA-responsive genes and the accumulation of ABA Insensitive 5(ABI5),causing mutant plants with ABA-insensitive phenotypes during seed germination and seedling growth,and decreased drought stress resistance.ABA treatment upregulates the expression of XIW1,and both ABA and abiotic stresses promote XIW1 accumulation in the nucleus,where it interacts with ABI5.Loss of XIW1 function results in rapid proteasomal degradation of ABI5.Taken together,these findings suggest that XIW1 is a nucleocytoplasmic shuttling protein and plays a positive role in ABA responses by interacting with and maintaining the stability of ABI5 in the nucleus. | Xuezhong XU Wang Wan Guobin Jiang Yue Xi Haijian Huang Jiajia Cai Yanan Chang Cheng-Guo Duan Satendra KMangrauthia Xinxiang Peng Jian-Kang Zhu Guohui Zhu | 2019 | Molecular Plant2019，12，12： | 8 |
| 12 | Heat shock induction of a 65 kDa ATP-binding proteinase in rat C6 glioma cells显示文摘The 45, 55, 65 and 100 kDa ATP-binding proteinases (ATP-BPases) of the heat-shocked (44 ℃ for 30 min, recovery for 12h) rat C6 glioma cells were purified by DEAE-ionexchange and ATP-affinity chromatography. Their molecular masses, isoelectric points (pI), pH-optima and other properties were analyzed by native proteinase gels.It was shown that the 65 kDa ATP-BPase is specifically induced by heat shock and not detectable in control cells.Its N-terminal 1-9 amino acid sequence was determined by Edman degradation, but no homologies to other proteins in the protein data bases were found. 30 and 31 kDa proteinases can be cleaved from the 45, 55 and 65 kDa proteinases to which they are linked. A possible relationship of the heat-induced 65 kDa ATP-BPase with the ATP-dependent proteinases (ATP-DPases) in prokaryotes and eukaryotes is discussed. | XU CUN SHUAN WEI MING ZHANG DIETER TECHEL MARCO MEYER YAN ZHANG LI LUDGER RENSING (Department of Biology, Henan Normal University,Xinxiang 453002)(Institute of Cell Biology, Bremen University, D-28359 Bremen, Germany) | 1999 | Cell Research1999，9，2： | 8 |

| 15 | Current status of laparoscopic and robotassisted nerve-sparing radical cystectomy in male patients显示文摘During radical cystectomy(RC),the neurovascular bundles are easily removed or damaged,leading to varying rates of incontinence and erectile dysfunction.The nervesparing technique was developed to preserve urinary and erectile function.The adoption of laparoscopic and robot-assisted technology has improved visualization and dexterity of pelvic surgeries,thus facilitate the nerve-sparing technique.Although nerve-sparing RC is technically similar with nerve-sparing radical prostatectomy,there are still some anatomical differences.There are mainly three different types of nerve-sparing techniques.Pelvic lymph node dissection(PLND)is another important factor to influence erectile function and urinary continence.Nerve-sparing laparoscopic radical cystectomy(LRC)and robot-assisted radical cystectomy(RARC)may be an optimal treatment choice in well-selected younger patients with lowvolume,organ-confined disease.We should attempt to do,whenever possible,a nerve-sparing cystectomy at least on oneside.However,due to the need of a well-refined surgical technique,nerve-sparing LRC and RARC is now being performed only by experienced urological surgeons. | Jian Huang Xinxiang Fan Wen Dong | 2016 | Asian Journal of Urology2016，3，3： | 7 |
