| 摘 要： | 在不同氮素水平下,研究小黑麦叶片蛋白质差异表达,进行MALDI-TOF-MS和生物信息学分析。找到7个差异表达蛋白,即与蛋白质合成和信号传导相关的蛋白、与清除自由基有关的酶、与叶绿体的发育和代谢有关蛋白、与植物碳代谢有关的酶、与氮素同化有关的酶。氮素对植物生长发育、物质代谢和信号传导影响全面,从蛋白点的鉴定分析来看,功能蛋白是其影响的重点。

| Abstract: | Proteins differential expression under different nitrogen levels were analyzed in triticale. Seven differentially expressed proteins were found by MALDI-TOF-MS and bioinformatics analysis, including proteins related with protein synthesis and signal transduction, enzyme related with elimination of the free radical, pro- teins related with chloroplast growth and metabolism, enzyme related with carbon metabolism, and enzyme related with nitrogen assimilation. Nitrogen had overall effects on growth, substance metabolism and signal conduction of plant. Identification and analysis on protein spots showed that the emphasis of its influence was functional proteins. |
