摘 要: 目的:研究乙烯信号通路在高盐胁迫诱导衰老中的作用。方法:应用基因芯片技术手段、Cluster聚类分析及Treeview软件分析高盐诱导的衰老基因与乙烯信号通路的关系。结果:二者之间的关系可以分为5个类群:(I)盐上调的EIN3/EIL1依赖型;(II)盐上调EIN3下调;(III)盐上调的EIN3/EIL1非依赖型;(IV)盐下调EIN3上调;(V)盐下调的EIN3/EIL1非依赖型。结论:高盐诱导的衰老基因表达与乙烯信号通路的关系可以分析EIN3/EIL1依赖与非依赖型。
关 键 词: 植物生理学;高盐胁迫;衰老;聚类分析;基因芯片;乙烯信号通路

Abstract: Objective: To study the role of ethylene signal pathway in high salinity induced senescence associated gene (SAG) expression. Methods: Using microarray chip technique, Cluster analysis and treeview software to analyze the relationship between high salinity induced senescence associated gene and ethylene signal pathway. Results: Relationship between high salinity induced SAG and EIN3 categorized in detail into five types: (I) Salt up-regulated genes dependent on EIN3/EIL1; (II) Up-regulated by salt and down-regulated by EIN3; (III) Salt up-regulated genes independent of EIN3/EIL1; (IV) Down-regulated by salt and up-regulated by EIN3; (V) Salt down-regulated genes independent of EIN3/EIL1. Conclusion: Take together, relationship between those categorized into EIN3/EIL1 dependent and independent.
Key words: plant physiology; high salinity stress; senescence: cluster analysis; microarray analysis; ethylene signal pathway
