| 1 | From concept to reality-A review to the primary test stand and its preliminary application in high energy density physics显示文摘Pulsed power technology,whereas the electrical energy stored in a relative long period is released in much shorter timescale,is an efficient method to create high energy density physics(HEDP)conditions in laboratory.Around the beginning of this century,China Academy of Engineering Physics(CAEP)began to build some experimental facilities for HEDP investigations,among which the Primary Test Stand(PTS),a multi-module pulsed power facility with a nominal current of 10 MA and a current rising time~90 ns,is an important achievement on the roadmap of the electro-magnetically driven inertial confinement fusion(ICF)researches.PTS is the first pulsed power facility beyond 10 TW in China.Therefore,all the technologies have to be demonstrated,and all the engineering issues have to be overcome.In this article,the research outline,key technologies and the preliminary HEDP experiments are reviewed.Prospects on HEDP research on PTS and pulsed power development for the next step are also discussed. | Jianjun Deng Weiping Xie Shuping Feng Meng Wang Hongtao Li Shengyi Song Minghe Xia Ji Ce An He Qing Tian Yuanchao Gu Yongchao Guan Bin Wei Xianbin Huang Xiaodong Ren Jiakun Dan Jing Li Shaotong Zhou Hongchun Cai Siqun Zhang Kunlun Wang Qiang Xu Yujuan Wang Zhaohui Zhang Guilin Wang Shuai Guo Yi He Yiwei Zhou Zhanji Zhang Libing Yang Wenkang Zou | 2016 | Matter and Radiation at Extremes2016，1，1： | 19 |
| 2 | Phytophthora Effectors Modulate Genome-wide Alternative Splicing of Host mRNAs to Reprogram Plant Immunity显示文摘Alternative splicing(AS)of pre-mRNAs increases transcriptome and proteome diversity,regulates gene expression through multiple mechanisms,and plays important roles in plant development and stress responses.However,the prevalence of genome-wide plant AS changes during infection and the mechanisms by which pathogens modulate AS remain poorly understood.Here,we examined the global AS changes in tomato leaves infected with Phytophthora infestans,the infamous Irish famine pathogen.We show that more than 2000 genes exhibiting significant changes in AS are not differentially expressed,indicating that AS is a distinct layer of transcriptome reprogramming during plant-pathogen interactions.Furthermore,our results show that P.infestans subverts host immunity by repressing the AS of positive regulators of plant immunity and promoting the AS of susceptibility factors.To study the underlying mechanism,we established a luminescence-based AS reporter system in Nicotiana benthamiana to screen pathogen effectors modulating plant AS.We identified nine splicing regulatory effectors(SREs)from 87 P.infestans effectors.Further studies revealed that SRE3 physically binds U1-70K to manipulate the plant AS machinery and subsequently modulates AS-mediated plant immunity.Our study not only unveils genome-wide plant AS reprogramming during infection but also establishes a novel AS screening tool to identify SREs from a wide range of plant pathogens,providing opportunities to understand the splicing regulatory mechanisms through which pathogens subvert plant immunity. | Jie Huang Xinyu Lu Hongwei Wu Yuchen Xie Qian Peng Lianfeng Gu Juyou Wu Yuanchao Wang Anireddy SNReddy Suomeng Dong | 2020 | Molecular Plant2020，13，10： | 4 |
| 3 | A Phytophthora sojae gene of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) induced in host infection and its anti-oxidative function in yeast显示文摘Glyceraldehyde-3-phosphate dehydro- genase (GAPDH) is a multifunctional protein well defined in eukaryotes, especially in mammalian and Saccharomyces cerevisiae. Using the method of suppression subtractive hybridization (SSH), we identified a Phytophthora sojae cDNA coding GAPDH, which was up-regulated during the early stage of soybean infection. The termed PsGapdh gene pos- sessed three copies in the P. sojae genome. Its amino acid sequence harbored overall conserved domain of GADPH, homologous closest to GapC1 of Achlya bisexualis (oomycete) and adjoined to GapC2s of Odontella sinensis and Phaeodactylum tricornutum (diatom), on the C-Ⅱ branch of subfamily GapC in phylogeny tree of GAPDH. The transcrip- tional level of PsGapdh was up-regulated throughout early infection. Heterogenous expression of PsGapdh in the yeast tdh1-deleted mutant could rescue growth arrest under continuous exposure to H2O2. These results indicated active roles of PsGapdh in patho- gen-host interaction and anti-oxidation. | ZENG Juan WANG Yuanchao SHEN Gu ZHENG Xiaobo | 2006 | Chinese Science Bulletin2006，51，11： | 2 |
| 4 | Hormones and carbohydrates synergistically regulate the formation of swollen roots in a Chinese cabbage translocation line显示文摘The genus Brassica contains a rich diversity of species and morphological types,including leaf,root,and oil crops,all of which show substantial phenotypic variation.Both Chinese cabbage and cabbage are typical leaf-type crops with normal roots.We created translocation lines based on interspecific crosses between Chinese cabbage and cabbage and identified qdh225,which exhibited a swollen-root phenotype.The swollen root of qdh225 contained a large number of granular substances,and the formation of its irregular morphological tissue was caused by a thickening of the phloem.Transcriptomic and metabolomic data suggested that differential expression of genes encoding nine types of enzymes involved in starch and sucrose metabolism caused changes in starch synthesis and degradation in the swollen root.These genes jointly regulated sucrose and starch levels,leading to significant enrichment of starch and soluble proteins in the swollen root and a reduction in the content of soluble sugars such as d-glucose and trehalose 6-phosphate.A significant increase in auxin(IAA)and abscisic acid(ABA)contents and a decrease in gibberellin(GA)content in the swollen root likely promoted the differential expression of genes associated with hormone signal transduction,thereby regulating the development of the swollen root.Taken together,our data suggest that accumulation of IAA and ABA and reduction in GA promote swollen root formation by regulating hormone-mediated signaling,leading to a thickening of phloem,root enlargement,and substantial accumulation of starch and soluble proteins.The latter provide materials,energy,and nutrient sources for the development of swollen roots. | Xiaojing Ren Wei Ma Shuxin Xuan Dandan Li Yanhua Wang Yuanchao Xu Daling Feng Jianjun Zhao Xueping Chen Shuangxia Luo Shuxing Shen Aixia Gu | 2023 | Horticulture Research2023，10，8： | 0 |
