植物叶片H_2O_2胁迫应答蛋白质组学分析

H_2O_2-responsive proteomics in plant leaves

植物叶片是感知外界H_2O_2胁迫信号的重要器官.整合分析了水稻(Oryza sativa)、小麦(Triticum aestivum)、二穗短柄草(Brachypodium distachyon)和柑橘(Citrus aurantium)在应对不同程度H_2O_2胁迫时蛋白质表达模式的变化特征.阐明了H_2O_2胁迫应答网络体系中的信号与代谢通路(如:光合作用、糖类与能量代谢、转录调控、蛋白质合成与命运、胁迫防御、信号转导和基础代谢等)的变化及植物叶片应答H_2O_2胁迫的分子调控机制.

Plant leaves are important organ for sensing H_2O_2 signals. This paper analyzes the diverse prote in patterns in plants such as Oryza sativa,Triticum aestivum,Brachypodium distachyon and Citrus aurantium under various H_2O_2 stress conditions. The change of signaling and metabolic pathways( such as photosynthesis,carbohydrate and energy metabolism,transcriptional regulation,protein synthesis and fate,stress and defense,signal transduction,basal metabolism,etc.) when the leaves put in H_2O_2-responsive networks were clarified. And the molecular regulatory mechanism of response to H_2O_2 stress in plant leaves was expounded as well.
