| 1 | Recent Advances in the Regulation of Brassinosteroid Signaling and Biosynthesis Pathways显示文摘Brassinosteroids(BRs) play important roles in plant growth,develop-ment and responses to environmental cues.BRs signal through plasma membrane receptor BRI1 and co-receptor BAK1,and several positive(BSK1,BSU1,PP2A) and negative(BKI1,BIN2 and 14-3-3) regulators to control the activities of BES1 and BZR1 family transcription factors,which regulate the expression of hundreds to thousands of genes for various BR responses.Recent studies identified novel signaling components in the BR pathways and started to establish the detailed mechanisms on the regulation of BR signaling.In addition,the molecular mechanism and transcriptional network through which BES1 and BZR1 control gene expression and various BR responses are beginning to be revealed.BES1 recruits histone demethylases ELF6 and REF6 as well as a transcription elongation factor IWS1 to regulate target gene expression.Identification of BES1 and BZR1 target genes established a transcriptional network for BR response and crosstalk with other signaling pathways.Recent studies also revealed regulatory mechanisms of BRs in many developmental processes and regulation of BR biosynthesis.Here we provide an overview and discuss some of the most recent progress in the regulation of BR signaling and biosynthesis pathways. | Huaxun Ye Lei Li Yanhai Yin | 2011 | Journal of Integrative Plant Biology2011，53，6： | 21 |
| 2 | Histone Lysine Methyltransferase SDG8 Is Involved in Brassinosteroid-Regulated Gene Expression in Arabidopsis thaliana显示文摘植物类固醇荷尔蒙, brassinosteroids (BR ) ,在植物生长,开发,和对 environmentalstresses 的回答起重要作用。BR 通过对血浆膜和另外的发信号的部件局部性的受体发信号调整抄写因素的 BES1/BZR1family,它调制几千基因的表示。BES1/BZR1 和他们的 interactingproteins 怎么工作调整基因的大数字,完全没被理解。这里,我们报导那 histone lysinemethyltransferase SDG8,在 histone 含有 3 离氨酸 36 di- 和 trimethylation (H3K36me2 和 me3 ) ,涉及 BR-regulatedgene 表示。BES1 与 SDG8 交往,直接或间接地通过 IWS1,抄写延伸因素 involvedin 调整 BR 的基因表示。猛烈变异的 sdg8 与损害 BR 回答显示减少的生长显型。全球基因表示研究表明了那, whileBR 在野类型的植物调整大约 5000 基因,荷尔蒙在 sdg8 比 700 基因调整少数变异。另外,多于调整 BR 的基因的一半,差别在 sdg8 异种被影响。一个染色质 Immunoprecipitation (薄片) 实验证明 H3K36me3 在 sdg8 异种在调整 BR 的基因被减少。把结果基于这些,我们建议 SDG8 在调停起一个必要作用调整 BR 的基因表示。Ourresults 因此揭示 histone 修正由支配基因 expression.Key 词的神经质的规定的主要机制: | Xiaolei Wang Jiani Chen Zhouli Xie Sanzhen Liu Trevor Nolan Huaxun Ye Mingcai Zhang Hongqing Guo Patrick S.

| 3 | Light Intensity Affects Chlorophyll Synthesis During Greening Process by Metabolite Signal from Mitochondrial Alternative Oxidase in Arabidopsis显示文摘Although mitochondrial alternative oxidase(AOX)has been proposed to play essential roles in high light stress tolerance,the effects of AOX on chlorophyll synthesis are unclear.Previous studies indicated that during greening,chlorophyll accumulation was largely delayed in plants whose mitochondrial cyanide-resistant respiration was inhibited by knocking out nuclear encoded AOX gene.Here we show that this delay of chlorophyll accumulation was more significant under high light condition.Inhibition of cyanide-resistant respiration was also accompanied by the increase of plastid NADPH/NADP^+ratio,especially under high light treatment which subsequently blocked the import of multiple plastidial proteins,such as some components of the photosynthetic electron transport chain,the Calvin-Benson cycle enzymes and malate/oxaloacetate shuttle components.Over expression of AOXla rescued the aoxla mutant phenotype,including the chlorophyll accumulation during greening and plastidial protein import.It thus suggests that light intensity affects chlorophyll synthesis during greening process by a metabolic signal,the AOX-derived plastidial NADPH/NADP^+ratio change.And our results thus revealed a molecular mechanism of chloroplast-mitochondria interactions. | ZHANG Dawei YUAN Shu 徐飞 ZHU Feng YUAN Ming YE Huaxun GUO Hongqing LV Xin YIN Yanhai 林宏辉 | 2015 | 武汉生物工程学院学报2015，，3： | 2 |
| 4 | Physical simulation experiment and numerical inversion of the full life cycle of shale gas well显示文摘The ultra-low porosity and permeability,as well as complex occurrence and transport state of shale reservoir make it possess special L-type production characteristic curve and complicated shale gas flow mechanism.To solve the difficulty of collecting complete production data due to short production time and operation discontinuity,a full-diameter core physical simulation experiment on the full lifecycle production process of shale gas well depletion is conducted with the purpose of obtaining many important production data including complete pressure and daily gas output in the simulated production process of shale gas well.The experimental results show the production characteristic from simulation is consistent with those from gas well.Based on the simulation data,the critical desorption pressure(12 MPa)of core,free gas production(3820.8 mL),adsorbed gas production(2151.2 mL),the proportion of the daily gas production between free and absorbed gas under different time and formation pressure,as well as the production time and final recovery rate corresponding to abandoned pressure,can be determined accurately.Numerical inversion is carried out to calculate the production performance curve of shale gas well and predict the development effect of gas well based on well testing and similarity analysis of the dimensionless time between core experiment and gas well production.Finally,the permeability and the fracturing effect(fracture network density)as the keys to the effective development of shale gas reservoirs are proposed.The permeability is the fundamental factor and the fracturing technology is the major means. | Shusheng Gao Huaxun Liu Liyou Ye Zhiming Hu Weiguo An | 2019 | Petroleum Research2019，4，2： | 0 |
