摘要: 水稻类病变突变体chl1具有抗病性增强的类病变表型,对水稻白叶枯病和稻瘟病都具有很强的抗性。利用蛋白质组学技术分析chl1与其野生型之间的差异表达蛋白,探讨chl1类病变表型的形成和抗病反应的分子机制。利用荧光双向差异凝胶电泳(twodimensional fluorescence difference gel electrophoresis, 2DDIGE)技术和质谱分析,chl1中共鉴定到70个差异表达的蛋白点,包括46个上调蛋白点和24个下调蛋白点。这些蛋白点参与不同的生物过程,包括防御相关、光合作用、氧化还原、氨基酸/蛋白质代谢、分子伴侣、碳水化合物代谢。对这些差异表达蛋白进行生物信息分析,推测它们所在的复杂调控网络可能参与chl1叶片细胞程序性死亡(programmed cell death, PCD)及其抗病性的调控。

Abstract: A lesionmimic mutant in rice (Oryza sativa L.), chloroplasticH2O2induced lesion 1 (chl1), has enhanced resistance to rice blast and bacterial blight. To understand the molecular mechanisms underlying this phenotype and its resistance responses, a proteomicsbased approach was used to identify  differentiallyexpressed proteins between chl1 and its wild type. Using twodimensional fluorescence difference gel electrophoresis technology and mass spectrometry, 70 protein spots were successfully identified, of which 46 were upregulated and 24 were downregulated in the mutant. These differentiallyexpressed proteins are involved in diverse biological processes including disease resistance, photosynthesis, oxidationreduction reaction, amino acid/protein metabolism, chaperoning and carbohydrate metabolism. The complex regulatory network in which these proteins are involved may play an important role in regulating the programmed cell death and the resistance reaction in chl1.

Key words: rice, lesionmimic mutant, programmed cell death, disease resistance, 2DDIGE
