| 摘 要： | 以培养84 h种子的胚芽(包括胚芽鞘)为试验材料, 对优良玉米杂交种先玉335与其亲本自交系的蛋白质组学差异进行了分析。结果表明, 在杂交种先玉335中共检测到560个蛋白点, 在亲本PH6WC和PH4CV分别检测到507个和508个蛋白点, 而且先玉335胚芽及胚芽鞘中81%的蛋白点表现非加性累积模式, 其中 288个蛋白点表现为超高亲的上调表达, 仅15个蛋白点表现超低亲的下调表达, 因此推测非加性蛋白的累积可能是杂交种先玉335胚芽萌发过程中胚芽及胚芽鞘杂种优势产生的主要原因。用于质谱分析的13个差异极显著蛋白主要涉及代谢途径、蛋白折叠、胁迫响应、细胞骨架和细胞解毒5种类型。

| Abstract: | The plumule(including coleoptile) of seed cultured for 84 h was used as materials to analyze the proteomic difference between the elite hybrid Pioneer 335 and its parental lines by mean of 2-D electrophoresis method.The results showed that 560 protein spots were identified in Pioneer 335,507 and 508 protein spots parental lines in its PH6WC and PH4CV,respectively.And in Pioneer 335,81% protein spots exhibited nonadditive expression model.Out of them,288 showed up-regulation with over high parent expression ... |
