摘要: 利用酚抽提法分别提取对照、3% NaHCO3处理5 d和10 d的西伯利亚蓼地茎、茎和叶部蛋白,用十二烷基硫酸钠-聚丙烯酰胺凝胶电泳(SDS-PAGE)和分析软件(Labw ork 3.0)对提取蛋白进行分离和定量分析。结果表明,地茎蛋白图谱在34.1和25.0×103D位置处出现了两条明显受正向调控的蛋白条带,茎部蛋白图谱在58.1×103D、47.8×103D和9.6×103D位置处出现三条正向调控的条带,叶组织蛋白图谱在25.0×103D处出现一受正调控的条带。除地茎和叶组织在25.0×103D处同时出现受正向调控的蛋白条带外,盐处理后其它组织间表达受正向调控的蛋白条带间存在差异,说明西伯利亚蓼不同部位对外界盐胁迫应答存在多样性。

Abstract: Proteins in under-ground stem,stem and leaf tissues of Polygonum sibiricum which were watered with 3% NaHCO 3 for 5 days,10 days and with tap water for control were extracted by phenol extraction method and separated and analyzed by SDS-PAGE and the related software labword version 3.0.The results show that two bands were up-regulated in the map of the under-ground tissue with the molecular weights of 34.1×103D and 25.0×103D,three bands were up-regulated in the map of the stem tissue with the molecular weights of 58.1×103D、47.8×103Dand 9.6×103D and one band was up-regulated in the map of the leaf tissue with the molecular weight of 25.0×103D.Apart from the same band at 25×103D position on the maps of the under-ground stem tissue and the leaf tissue,the bands at other positions on the maps of three parts of the plant which were up-regulated were different.The diversities of the patterns of protein expression in different parts of the plant are illuminated by the results that were gained.
