| 1 | Quantitative Trait Loci Mapping of Dark-Induced Senescence in Winter Wheat(Triticum aestivum)显示文摘In order to explore the genetics of dark-induced senescence in winter wheat(Triticum aestivum L.),a quantitative trait loci(QTL)analysis was carried out in a doubled haploid population developed from a cross between the varieties Hanxuan 10(HX)and Lumai 14(LM).The senescence parameters chlorophyll content(Chl a+b,Chl a,and Chl b),original fluorescence(Fo),maximum fluorescence level(Fm),maximum photochemical efficiency(Fv/Fm),and ratio of variable fluorescence to original fluorescence(Fv/Fo)were evaluated in the second leaf of whole three-leaf seedlings subjected to 7 d of darkness.A total of 43 QTLs were identified that were associated with dark-induced senescence using composite interval mapping.These QTLs were mapped to 20 loci distributed on 11 chromosomes:1B,1D,2A,2B,3B,3D,5D,6A,6B,7A,and 7B.The phenotypic variation explained by each QTL ranged from 7.5% to 19.4%.Eleven loci coincided with two or more of the analyzed parameters.In addition,14 loci co-located or were linked with previously reported QTLs regulating flag leaf senescence,tolerance to high light stress,and grain protein content(Gpc),separately. | Hongwei Li Fanyun Lin Gui Wang Ruilian Jing Qi Zheng Bin Li Zhensheng Li | 2012 | Journal of Integrative Plant Biology2012，54，1： | 6 |
| 2 | Baicalin and jasminoidin effects on gene expression and compatibility in the hippocampus following focal cerebral ischemia显示文摘The compound traditional Chinese medicine Qingkailing,which is an ingredient used to treat cerebral ischemia,has been limited to studies concerning single genes or single pathways.Interactions and pharmacological mechanisms of the compound ingredients(baicalin and jasminoidin) remain poorly understood.In the present study,baicalin and jasminoidin,as well as the combination,were used to separately treat mouse models of cerebral ischemia.cDNA microarray analyses of 374 cerebral ischemia-related genes were utilized to determine changes in gene-expression profiles.Arraytrack 3.40 and Ingenuity Pathway Analysis(IPA) databases were utilized to analyze changes in gene molecular functions and network path functions.Baicalin or jasminoidin alone effectively reduced infarct area,and the combination resulted in significantly better outcomes.IPA showed inhibited cell apoptosis in the baicalin group and Ca2+ channel regulation in the jasminoidin group.The combination of baicalin and jasminoidin activated HTR3A and F5 expression,regulated Ca2+ channels,activated kappa light polypeptide gene enhancer inhibitor IKBKG in B cells to control IkB kinase/nuclear factor-kB cascade,suppressed activation of inflammatory cytokine interleukin-6 receptors and activated transduction of guanine-nucleotide-binding protein(G protein) signal.Results suggested that the combination of baicalin and jasminoidin resulted in similar molecular mechanisms to baicalin and jasminoidin alone.However,novel pharmacological actions of compatibility were detected,demonstrating significant protection against cerebral ischemia. | Guo, Lin Meng, Fanyun Zhang, Guodong Zhao, Jing Zhang, Zhanjun Zhou, Caixiu Wang, Zhong | 2011 | Neural Regeneration Research2011，6，3： | 2 |
