6MONOCULM 3,an Ortholog of WUSCHEL in Rice,Is Required for Tiller Bud Formation显示文摘WUSCHEL(WUS)plays an essential role for the maintenance of meristem activity in dicots,but its function is still elusive in monocots.We isolated a new monoculm mutant,monoculm 3(moc3),in which a point mutation causes the premature termination of rice O.sativa WUS(Os WUS).Morphological observation revealed that the formation of tiller buds was disrupted in moc3.MOC3 was localized in the nuclear and could interact with TOPLESS-RELATED PROTEINS(TPRs).The expression of MOC3 was induced by cytokinins and defection of MOC3 affected the expression of several two-component cytokinin response regulators,Os RRs and ORRs.Our results suggest that MOC3 is required for the formation of axillary buds and has a complex relationship with cytokinins.Zefu Lu Gaoneng Shao Jinsong Xiong Yongqing Jiao Jing Wang Guifu Liu Xiangbing Meng Yan Liang Guosheng Xiong Yonghong Wang Jiayang Li 2015Journal of Genetics and Genomics2015,42,2:17

9Tiller Bud Formation Regulators MOC1 and MOC3 Cooperatively Promote Tiller Bud Outgrowth by Activating F0N1 Expression in Rice显示文摘Tillering in rice is one of the most important agronomic traits.Rice tiller development can be divided into two main processes: the formation of the axillary bud and its subsequent outgrowth.Several genes critical for bud formation in rice have been identified by genetic studies;however,their molecular functions and relationships are still largely unknown.Here,we report that MONOCULM 1 (MOC1) and MONOCULM 3/ TILLERS ABSENT 1/STERILE AND REDUCED TILLERING 1 (MOC3/TAB1/SRT1),two vital regulators for tiller formation in rice,physically interact to regulate tiller bud outgrowth through upregulating the expression of FLORAL ORGAN NUMBER 1 (FON1),the homolog of CLAVATA1 in rice.We found that M0C3 is able to directly bind the promoter ofFONI and subsequently activate FON1 expression.MOC1 functions as a coactivator of MOC3,whereas it could not directly bind the FON1 promoter,and further activated FON1 expression in the presence of MOC3.Accordingly,FON1 is highly expressed at axillary meristems and shows remarkably decreased expression levels in mod and moc3 mutants.Loss-of-function mutants of FON1 exhibit normal bud formation but defective bud outgrowth and reduced tiller number.Collectively,these results shed light on a joint transcriptional regulatory mechanim by MOC1 and MOC3,and establish a new framework for the control of tiller bud formation and outgrowth.Gaoneng Shao Zefu Lu Jinsong Xiong Bing Wang Yanhui Jing Xiangbing Meng Guifu Liu Haiyan Ma Yan Liang Fan Chen Yonghong Wang Jiayang Li Hong Yu 2019Molecular Plant2019,12,8:15

13Influence of catgut implantation at acupoints on leptin and insulin resistance in simple obesity rats显示文摘OBJECTIVES:To investigate the influence of catgut implantation at acupoints on leptin resistance(LR) and insulin resistance(IR) in the simple obesity rat.METHODS:Rats were made obese with high-fat diets,after which surgical catgut was implanted at Zusanli(ST 36) and Neiting(ST 44) acupoints once a week for 4 weeks(implantation group).Rats from the implantation group were compared with normal rats and unoperated obese rats(control group).Gene expression of the leptin receptor(OB-R) was evaluated using RT-PCR and northern blot.Serum and hypothalamus leptin and insulin(INS) levels were determined by radioimmunoassay.Body weight,Lee's index,body fat,serum and hypothalamus leptin and INS levels,and hypothalamic OB-R gene expression were determined before and after treatment.RESULTS:Body weights,Lee's index,body fat,and serum leptin and INS levels were significantly higher in obese than in normal rats.Hypothalamic leptin and INS levels and OB-R gene expression were significantly lower in obese rats.Catgut implantation at acupoint promoted weight loss and decreased serum leptin and INS levels.Hypothalamic leptin and INS levels and OB-R gene expression increased significantly.CONCLUSIONS:Catgut implantation at acupoint adjusts central and peripheral leptin and promotes hypothalamic OB-R gene expression.This may be an important method for regulation of LR,IR and abnormal endocrinology and metabolism.Runhu Yan Xiaoming Liu Jie Bai Jiang Yu Jinsong Gu 2012Journal of Traditional Chinese Medicine2012,32,3:12
14Relationships between vegetation and stomata,and between vegetation and pollen surface soil in Yunnan,Southwest China显示文摘Surface pollen and stomata of 61 samples collected in a study area ranging from tropical seasonal rainforest to oak forest(Quercus spinosa) in the Yulong Snow Mountain region in Yunnan,China,are used to distinguish vegetation communities.The results show that tropical seasonal rainforest(and mountain rainforest),south subtropical evergreen broad-leaved forest,and Quercus shrub are distinguished effectively from other vegetation types by analysis of surface pollen.The south subtropical evergreen broad-leaved forest,Pinus kesiya forest and evergreen broadleaf forest are distinguished effectively from other types of vegetation by pollen analysis.However,P.yunnanensis forest is not distinguished from other vegetation types,and P.armandii,P.densata forest and temperate deciduous conifer mixed forest are not distinguished.The over-representation of Pinus pollen is the main reason that these vegetation communities are not distinguished from each other.Conifer stomata analysis is an effective tool for identifying and distinguishing different types of coniferous forest,and this method performs well even with a small number of sampling points.SHEN HuaDong LI ChunHai WAN HeWen TONG GuoBang LIU JinSong DAN Johnson 2013Chinese Science Bulletin2013,58,15:12
15Optimal design of a new spatial 3-DOF parallel robot with respect to a frame-free index显示文摘Optimal design is one of the most important issues in robots. Since the very beginning, the concepts of the Jacobian matrix, manipulability and condition number, which are used successfully in the field of serial robots, have been applied to parallel robots. Unlike serial robots, parallel robots are good for motion/force transmission. Their performance evaluation and design should be correspondingly dif- ferent. This paper is an attempt to optimally design a novel spatial three-degree-of-freedom (3-DOF) parallel robot by using the concept of motion/force transmission. Accordingly, three indices are defined. The suggested indices are independent of any coordinate frame and could be applied to the analysis and design of a parallel robot whose singularities can be identified wholly by using the relative angle between the output and adjacent links, and by using the relative angle between the input and adjacent links.JinSong Wang XinJun Liu Chao Wu 2009Science China(Technological Sciences)2009,52,4:12

17Radial profile of sap flow velocity in mature Xinjiang poplar(Populus alba L. var. pyramidalis) in Northwest China显示文摘Estimation of the transpiration rate for a tree is generally based on sap flow measurements within the hydro-active stem xylem. In this study, radial variation of sap flow velocity(Js) was investigated at five depths of the xylem(1, 2, 3, 5 and 8 cm under the cambium) in three mature Xinjiang poplar(Populus alba L. var. pyramidalis) trees grown at the Gansu Minqin National Studies Station for Desert Steppe Ecosystem from May to October 2011. Thermal dissipation probes of various lengths manufactured according to the Granier's design were installed into each tree for simultaneous observation of the radial patterns of Js through the xylem. The radial patterns were found to fit the four-parameter GaussAmp equation. The peak Js was about 27.02±0.95 kg/(dm2?d) at approximately 3 to 5 cm deep from the cambium of the three trees,and the lowest Js appeared at 1 cm deep in most of the time. Approximately 50% of the total sap flow in Xinjiang poplar occurred within one-third of the xylem from its outer radius, whereas 90% of the total sap flow occurred within two-fifth of the xylem. In addition, the innermost point of the xylem(at 8-cm depth), which appeared as the penultimate sap flow in most cases during the study period, was hydro-active with Js,8 of 7.55±3.83 kg/(dm2?d). The radial pattern of Js was found to be steeper in midday than in other time of the day, and steeper diurnal fluctuations were recorded in June, July and August(the mid-growing season). Maximum differences between the lowest Js(Js,1 or Js,8) and the highest Js(Js,3 or Js,5) from May through October were 12.41, 17.35, 16.30, 18.52, 12.60 and 16.04 g/(cm2?h), respectively. The time-dependent changes of Js along the radial profile(except at 1-cm depth) were strongly related to the reference evapotranspiration(ET0). Due to significant radial variability of Js, the mean daily sap flow at the whole-tree level could be over-estimated by up to 29.69% when only a single probe at depth of 2 cm was used. However, the accuracy of the estimation of sap flow in Xinjiang poplar could be significantly improved using a correction coefficient of 0.885.HongZhong DANG TianShan ZHA JinSong ZHANG Wei LI ShiZeng LIU 2014Journal of Arid Land2014,6,5:11
18EZH2-, CHD4-, and IDH-linked epigenetic perturbation and its association with survival in glioma patients显示文摘Glioma 是有有限治疗选择的复杂疾病。最近的进展在多达 80% 更低的等级 gliomas (LGG ) 并且在 76% 第二等的 glioblastomas (GBM ) 识别了 isocitrate 脱氢酶(IDH ) 变化。IDH 变化也在尖锐 myeloid 白血病(AML ) 的 10%-20% 被看见。在 AML,包含 epigenetic 规定的 IDH 和另外的基因的变化是早事件,这被决定,出现在 pre 白血病的干细胞(最低有效字符前) 上演,而在宣传 oncogenic 信号的基因的变化是在白血病的迟了的事件。IDH 变化也是在 glioma 的早事件,发生在 TP53 变化前, 1p/19q 删除,等等。尽管有在 glioma 研究的这些进展,进另外的分子的改变的研究更加落后。在这研究,我们分析了当前可得到的数据库。我们除了已知的基因 IDH1/2 在 glioma 识别了 EZH2, KMT2C,和 CHD4 同样重要的基因。我们也证明 PIK3CA, CDKN2A, CDK4, FIP1L1,或 FUBP1 的 genomic 改变与 IDH 变化协作否定地在 LGG 影响病人幸存。在有 TP53 变化或 IDH1/2 变化的 LGG 病人,没有如此的改变, EZH2, KMC2C,和 CHD4 的另外的 genomic 改变个别地或在联合比病人与显著地减少的没有疾病的幸存被联系。在基因水平或蛋白质水平的 EZH2, KMT2C,和 CHD4 的改变能使不安 epigenetic 节目,在 glioma 导致恶意的转变。由在可得到的数据集上在 AML 和 glioma 和表现生物信息学分析上考察当前的文学,我们从 premalignant 干细胞在 tumorigenesis 上开发了一个假想模型到 glioma。Le Zhang Ying Liu Mengning Wang Zhenhai Wu Na Li Jinsong Zhang Chuanwei Yang 2017Journal of Molecular Cell Biology2017,9,6:11
19Geophysical methods for the study of sedimentary cycles显示文摘We present the wavelet depth-frequency analysis and variable-scale frequency cycle analysis methods to study sedimentary cycles.The spectrum analysis,variable-scale frequency cycle analysis, and wavelet depth-frequency analysis methods are mainly discussed to distinguish sedimentary cycles of different levels.The spectrum analysis method established the relationship between the spectrum characteristics and the thickness and number of sedimentary cycles.Both the variable-scale frequency cycle analysis and the wavelet depth-frequency analysis are based on the wavelet transform.The variable-scale frequency cycle analysis is used to obtain the relationship between the periodic changes of frequency in different scales and sedimentary cycles,and the wavelet depth-frequency analysis is used to obtain the relationship between migration changes of frequency energy clusters and sedimentary cycles. We designed a software system to process actual logging data from the Changqing Oilfield to analyze the sedimentary cycles,which verified the effectiveness of the three methods,and good results were obtained.Xu Jingling Liu Luofu Wang Guiwen Shen Jinsong Zhang Chunhua 2009Petroleum Science2009,6,3:10
20Rapid genomic changes in polyploid wheat and related species:implications for genome evolution and genetic improvement显示文摘A polyploid organism by possessing more than two sets of chromosomes from one species (autopolyploidy) or two or more species (allopolyploidy) is known to have evolutionary advantages. However, by what means a polyploid accommodates increased genetic dosage or divergent genomes (allopolyploidy) in one cell nucleus and cytoplasm constitutes an enormous challenge. Recent years have witnessed efforts and progress in exploring the possible mechanisms by which these seemingly intangible hurdles of polyploidy may be ameliorated or eventually overcome. In particular, the documentation of rapid and extensive non-Mendelian genetic and epigenetic changes that often accompany nascent polyploidy is revealing: the resulting non-additive and novel gene expression at global, regional and local levels, and timely restoration of meiotic chromosomal behavior towards bivalent pairing and disomic inheritance may ensure rapid establishment and stabilization as well as its long-term evolutionary success. Further elucidation on these novel mechanisms underpinning polyploidy will promote our understanding on fundamental issues in evolutionary biology and in our manipulation capacities in future genetic improvement of important crops that are currently polyploids in genomic constitution. This review is intended to provide an updated discussion on these interesting and important issues within the scope of a specific yet one of the most important plant groups-polyploid wheat and its related species.Bao Liu Chunming Xu Na Zhao Bao Qi Josphert N.
