- 摘要:
- 对大豆光周期敏感型品种东农42分别进行16 h光照和8 h光照处理,提取处理和对照相同叶位叶片的全蛋白质进行双向电泳,通过PDQuest和液相离子阱质谱(LC-ESI-MS)技术对差异表达蛋白进行分析,获得二级质谱图谱,用Mascot软件搜索NCBInr数据库,鉴定出16个差异表达蛋白,其中12个表达量上调,4个表达量下调。对谷胱甘肽 S转移酶、二硫键异构酶、TCTP、半胱氨酸合成酶、Rieske铁硫蛋白前体、金属蛋白酶等主要差异蛋白进行功能分析,表明这些蛋白与植物的光合作用、信号转导、细胞凋亡的调控、防卫解毒和能量代谢等多种植物的生理生化功能相关。
- Abstract:
- Dongnong 42,a photoperiod sensitive cultivar,was treated with 8 h and 16 h light illuminations,respectively.The leaf tissues were then sampled and two-dimensional gel electrophoresis(2-DE)was performed to separate the protein spots.The gels were stained with Coomassie Blue G-250.The difference between the protein maps of leaves from two different photoperiod treatments was analyzed with the PDQuest image software(Bio-rad).The liquid and ion trap mass spectrometry(LC-ESI-MS)was used to obtain the MS/MS of the differentially expressed proteins and the MASCOT software was used to search the protein database.A total of 16 differentially expressed proteins were identified,of them nine proteins showed up-regulation expression and four showed down-regulation expression.The major differentially expressed proteins,glutathione-S-transferase,disulfide isomerase,metalloproteinases,TCTP,Rieske iron-sulphur protein precursor cysteine synthetic enzymes,were reviewed and discussed.These proteins might be related to plant photosynthesis,signal transduction and apoptosis control,detoxification and plant defense and other physiological and biochemical function.
