1MYB106 is a negative regulator and a substrate for CRL3^(BPM) E3 ligase in regulating flowering time in Arabidopsis thaliana显示文摘Flowering time is crucial for successful reproduction in plants, the onset and progression of which are strictly controlled. However, flowering time is a complex and environmentally responsive history trait and the underlying mechanisms still need to be fully characterized. Post-translational regulation of the activities of transcription factors(TFs) is a dynamic and essential mechanism for plant growth and development. CRL3 BPME3 ligase is a CULLIN3-based E3 ligase involved in orchestrating protein stability via the ubiquitin proteasome pathway. Our study shows that the mutation of MYB106 induced early flowering phenotype while over-expression of MYB106 delayed Arabidopsis flowering. Transcriptome analysis of myb106 mutants reveals 257 differentially expressed genes between wild type and myb106-1 mutants, including Flowering Locus T(FT) which is related to flowering time. Moreover, in vitro electrophoretic mobility shift assays(EMSA), in vivo chromatin immunoprecipitation quantitative polymerase chain reaction(ChIP-q PCR) assays and dual luciferase assays demonstrate that MYB106 directly binds to the promoter of FT to suppress its expression. Furthermore, we confirm that MYB106 interacts with BPM proteins which are further identified by CRL3 BPME3 ligases as the substrate. Taken together, we have identified MYB106 as a negative regulator in the control of flowering time and a new substrate for CRL3 BPM E3 ligases in Arabidopsis.Liu Hong Fangfang Niu Youshun Lin Shuang Wang Liyuan Chen Liwen Jiang 2021Journal of Integrative Plant Biology2021,63,6:3

4A Preliminary Study on the Datong Fault Belt显示文摘The Datong fault belt is a NE trending fault in the northern Qinghai-Xizang (Tibet) Plateau and controls the boundary of the Xining Basin and Datong Basin. It consists of the Maziying-Miaogou (F_1) fault and the Laoye Mountain-Nanmenxia fault (F_2). There is obvious displacement in vertical direction along the belt. The field investigation results show that this belt has long-term activity. There are several meters long crushed zones and veins along the fault side in the basement rock. On the fault section,the Cambria system thrusts over the red-brick-colored Quaternary Period gravel,and there is a fault gouge of several centimeters thick developed on the fault plane. The fault gouge date (ESR) on the fault plane is 610±61ka. The covering deluvial loess is not dislocated,and the OSL result is 14.6±1.5ka. So it can be concluded that the fault belt was active in the middle Pleistocene,but inactive in the late Pleistocene according to the age data and geomorphologic features. Interior formations of the Datong basin features fold with the major axis orienting northwest. According to the relation of fault and fold deformation,Datong fault is a transversal tear,which is due to uneven compression of the folds in different parts and NNE trending regional compressive stress. It is common among the NE trending faults in the northeast of Qinghai-Xizang (Tibet) Plateau. These NE trending faults aren't large,and most are located in the active plate. They are all nearly vertical to the axis of the folds and compressive basins.Li Zhimin Tian Qinjian Yao Shenghai Li Wenqiao Chen Youshun Zou Haining Gao Zhanwu 2008Earthquake Research in China2008,22,3:2

7Risk-opportunity analyses and production peak forecasting on world conventional oil and gas perspectives显示文摘To investigate the situation of conventional oil and gas,this paper examines the global oil and gas discoveries,proved reserves,production,consumption and price. All the inuencing factors can be subjected to risk and opportunity analyses,so in the paper,we build upon a risk-opportunity analysis framework,which is a new train of thought. To forecast the peak time of oil and gas production,we used the methods of multi-Hubbert model forecasting and data forecasting. Our results showed that the world oil production will reach a peak between 2010 and 2015 and the gas production will reach a peak around 2030 Oil peak is coming and gas peak is on the way. The main purpose of forecasting oil and gas production peak is give people enough time for preparing mitigation and adaptation plans. This means taking decisive action well before the problem is obvious.Zhang Jian Sun Zandong Zhang Yiwei Sun Youshun Nail Toksoz 2010Petroleum Science2010,7,1:1

12Crustal structure of the central Tibetan plateau and geological interpretation显示文摘Based on teleseismic data obtained from 225 stations from two networks in the central Tibetan plateau, we have generated detailed crustal structure images using P-wave receiver function techniques with more accurate piercing-depth-correction and time-depth-correction than what have previously been available. Our images indicate an undulatory Moho beneath the Tibetan plateau with a steep jump beneath the northern Himalaya, and obviously different structures in proximity to the Bangong-Nujiang suture. In several sections of the Tibetan plateau, the lower crust is characterized by pervasive high-velocity regions, which are consistent with the preservation of eclogite bodies beneath the plateau, whose presence affects the dynamics of the Tibetan plateau.Can Ge Youshun Sun M Nafi Toksz Yingcai Zheng Yong Zheng Xiong Xiong Diming Yu 2012Earthquake Science2012,25,5:0
13Depth determination of the Moho interface beneath the Tibetan plateau and other areas of China显示文摘We apply the adaptive moving window method of Sun et al. to the most recent catalog data and the data recorded by portable stations to construct the velocity structure of the crust and upper mantle, and to determine the depth of the Moho interface beneath the Tibetan plateau and other areas of China. We first select 2 600 locations in the study region with 1 intervals, then at each location invert for a five-layer 1-D P-wave velocity model from the surface down to the uppermost mantle by performing a Monte Carlo random search. The Moho depth at each location is then determined, and the Moho interface beneath the study region is obtained through proper interpolation with certain smoothing. Compared to depths obtained by previous studies, our results show more accurate Moho depths in the Tibetan plateau, Tianshan region and other areas of the study region.Youshun Sun Diming Yu M Nafi Toksz F Dale Morgan Xiyu Wang Jinrong Su Jun Liu 2012Earthquake Science2012,25,5:0
141-D P- and S-wave velocity models for the collision zone between the northern Tianshan mountain and the Junggar basin based on local earthquake data显示文摘We have developed crustal minimum 1-D P- and S-wave velocity models of the collision zone between the northern Tianshan mountain and the Junggar basin (86 E-89 E, 43 N-44.5 N). These two models were created through inversion of 1 370 P- and 1 396 S-wave travel times from 173 well-constrained local earthquakes recorded by the rmqi sparse local seismic network and temporary seismic arrays. In contrast to previous models, our results indicate relatively low velocity at both shallow (<10 km) and deep (30-45 km) depths. The shallow zone is interpreted to be the result of thick surficial sedimentary deposits, whereas the deeper anomaly is interpreted to result from ductile shearing and lower crustal flow. Additionally, we detected several transition layers under the lower crust, which may imply structural complexity of the uppermost mantle in this region. The improved models reduce the RMS residual of earthquake locations by 41.7% from 1.2 to 0.5 seconds. The more accurately located hypocenters appear to correlate with prominent local over-thrusts, which underlie an anticlinal fold belt and several blind faults. Positive station corrections are observed near the Junggar basin, which likely reflects low wave velocity; negative corrections near the Tianshan mountain and Bogda mountain suggest high wave velocity.Anhui Sun Youshun Sun Haijiang Zhang Diming Yu 2012Earthquake Science2012,25,5:0
15Crustal and uppermost mantle structure of Caucasus and surrounding regions显示文摘A 3-D P-wave velocity model is developed for the crust and uppermost mantle of Caucasus and the surrounding area by applying the tomographic method of Zhao et al. using 300 000 high-quality P-wave first arrivals from 43 000 events between 1964 and 2005. This tomographic method can accommodate velocity discontinuities such as the Moho in addition to smooth velocity variations. The spatial resolution is 1 ×1 in the horizontal direction and 10 km in depth. The velocity images of the upper crust correspond well with the surface geology. Beneath the southern Caucasus high velocity anomalies are found in the middle crust and low velocity anomalies are found in the uppermost mantle. Relatively low Pn velocities are located under the Lesser Caucasus, eastern Turkey, and northern Iran. Higher Pn velocities occur under the eastern portion of the Black Sea and the southern Caspian Sea, and also extend into the eastern edge of Azerbaijan. Tomographic model significantly reduces the travel-time residuals.Youshun Sun M Nafi Toksz Randolph J Martin Mary Krasovec Diming Yu Qingyun Liu Jun Liu 2012Earthquake Science2012,25,5:0
16Plant Rho GTPase signaling promotes autophagy显示文摘The roles of Rho family guanosine triphosphatases(GTPases)of plants(ROPs)in modulating plant growth and development have been well characterized.However,little is known about the roles of ROP signaling pathways in regulating plant autophagy and autophagosome formation.In this study,we identify a unique ROP signaling mechanism,which mediates developmental to autophagic transition under stress conditions in the model plant Arabidopsis.Loss-of-function mutants of ROP8 showed stress-induced hypersensitive phenotypes and compromised autophagic flux.Similar to other ROPs in the ROP/RAC family,ROP8 exhibits both plasma membrane and cytosolic punctate localization patterns.Upon autophagic induction,active ROP8 puncta colocalize with autophagosomal markers and are degraded inside the vacuole.In human cells,RalB,an RAS subfamily GTPase,engages its effector Exo84 for autophagosome assembly.However,a RalB counterpart is missing in the plant lineage.Intriguingly,we discovered that plant ROP8 promotes autophagy via its downstream effector Sec5.Live-cell super-resolution imaging showed that ROP8 and Sec5 reside on phagophores for autophagosome formation.Taken together,our findings highlight a previously unappreciated role of an ROP8-Sec5 signaling axis in autophagy promotion,providing new insights into how plants utilize versatile ROP signaling networks to coordinate developmental and autophagic responses depending on environmental changes.Youshun Lin Yonglun Zeng Ying Zhu Jinbo Shen Hao Ye Liwen Jiang 2021Molecular Plant2021,14,6:0
17The molecular basis of heat stress responses in plants显示文摘Global warming impacts crop production and threatens food security.Elevated temperatures are sensed by different cell components.Temperature increases are classified as either mild warm temperatures or excessively hot temperatures,which are perceived by distinct signaling pathways in plants.Warm temperatures induce thermomorphogenesis,while high-temperature stress triggers heat acclimation and has destructive effects on plant growth and development.In this review,we systematically summarize the heat-responsive genetic networks in Arabidopsis and crop plants based on recent studies.In addition,we highlight the strategies used to improve grain yield under heat stress from a source-sink perspective.We also discuss the remaining issues regarding the characteristics of thermosensors and the urgency required to explore the basis of acclimation under multifactorial stress combination.Yi Kan Xiao-Rui Mu Jin Gao Hong-Xuan Lin Youshun Lin 2023Molecular Plant2023,16,10:0
